Show Your Hand, Not Your ID The Chronicle of Higher Education, 5.12.2 http://chronicle.com/free/v52/i15/15a02801.htm [Colloquy transcript appended.] [Yes, I can see the advantages of using these scanners, and I think the concerns over theft and privacy issues are reasonably countered. But the real problem is that, in making such identifications mandatory, the informal and generally harmless violations of rules are no longer possible. Suppose a researcher wants to sneak a friend into his lab after hours. This, and many, many other technical violations will no longer be allowed. We must be ever vigilant about this kind of "unreasonableness of reason," to almost coin a meme. There is a single hit on Google! I lack a better term.] Colleges use biometric scanners to screen for access to dining halls, labs, dorms, gyms, and computer networks By VINCENT KIERNAN At many colleges, students flash a photo ID at a food-service worker to get into a dining hall. Things work differently at the University of Georgia, where Gavin Beck, a senior, places his hand on a sensor that determines if the person waiting to eat really is Gavin Beck. The process, which measures the size and shape of the hand, takes only a few seconds. "No system is foolproof, but this is far more efficient for us than a photo-based system," says J. Michael Floyd, director of food services at Georgia. The university is among the first to use the biometric technology widely, having relied on it in one form or another in its dining halls since 1974. Hand scanners, electronic fingerprint readers, even retina scanners are not just for super-spies in Hollywood movies anymore. The technology is increasingly being used by colleges to allow students, professors, and staff members to gain access to dining halls, laboratories, gyms, and other facilities on their campuses. Improvements in the technology are spurring greater interest among some college administrators. Faculty and staff members who seek weekend access to the Biodesign Institute at Arizona State University, for example, must be approved by a device that checks 240 points in the iris of the eye. Locks on dormitory doors at Johnson & Wales University at Denver are controlled by a hand-geometry reader similar to Georgia's. Food-service workers at Georgia punch in and out of their shifts with a time clock that scans their fingerprints so that a worker cannot clock in for an absent friend. Proponents say biometric technology offers increased security and efficiency, making lines move faster while keeping unauthorized visitors out. And at a time when colleges are trying to safeguard campus data, the technology offers colleges a new tool to control access to computers and networks. But cost and various technical obstacles are likely to slow the technology's adoption by colleges. And some observers worry that the systems could leave an electronic paper trail -- open to abuse or theft -- of the activities of students and faculty and staff members. "It's an extremely disturbing trend," says Lee Tien, a senior staff lawyer at the Electronic Frontier Foundation, a group that promotes online civil liberties. "Biometrics is a technology that is dangerous for privacy." How It Works Administrators who support the use of biometric technology say scanning body parts is far more secure than asking users for passwords, which can be forgotten or stolen. The scanning devices look for some unique characteristic of the user, such as the arrangement of ridges on the finger, the pattern of blood vessels in the eye, or the size and shape of the hand. The characteristic -- called a biometric measurement -- must be unique for each individual, must not change, and must be easily measured. Typically a person's hand, fingerprint, or eyeball is measured once when he or she is enrolled in the system, and that measurement is stored in a computer database or on a smart ID card. At the entrance to a controlled area, such as a dining hall, the individual's characteristic is measured again and compared with the original recording. If the two measurements match, the person is admitted. Georgia's early system recorded two-dimensional measurements of users' hands. But in 1995, as part of a campuswide move toward biometric identification, the system was upgraded to one that takes three-dimensional measurements. Now the 32,500 students use their hands as passports to all-you-can-eat meal plans, the recreation center, and dormitories. They either swipe an ID card through a card reader or enter an ID number on a keypad before presenting their hand for scanning. Mr. Floyd, the food-service director, says the system rarely misidentifies anyone. Mr. Beck, the Georgia senior, recalls only one glitch, when the system wouldn't recognize him at the start of fall semester, probably because of a subtle change in his hand's shape over the summer. At a nearby office, he showed his ID, had his hand rescanned, and was cleared to eat his meal. "It set me back a couple of minutes," he says, "but it was no big deal." The University of New Hampshire installed a hand-reading system in its dining halls when campus officials wanted to halt the sharing of all-you-can-eat meal plans by several people, says David J. May, executive director of hospitality services. "It really has worked wonderfully for us," he says. Although he cannot estimate the amount of fraud that the system has stopped, he is convinced that "students would beat the system if we were using ID cards." The cost of putting biometric security in place is not exorbitant, says Mr. May. Each hand reader costs about $2,500, and the turnstile to which it is connected costs $8,500 to $9,000. The 12,000-student university has seven biometric stations at its dining halls, he says. Recently, New Hampshire expanded the system to control employees' access to one of its dining halls. That way the university will not have to issue keys to employees -- or replace locks if keys are stolen. "If an employee leaves, we just take them out of the database," so the hand-reading system will no longer recognize that person, says Mr. May. Smaller-Scale Projects Biometric systems are also being used on a smaller scale on some campuses. At Rutgers University at New Brunswick, fingerprint-scanning devices are being installed on computers attached to laboratory equipment in the materials-science department. The department, with some 80 potential users of the technology, has a password system to track usage of the equipment, so that the appropriate research grant is charged. But some students complained that they were being charged for others' use, says W. Roger Cannon, a professor of materials science and engineering. That prompted him to investigate a biometric alternative. "If we had a fingerprint system, there would be no argument," he says. The new system has functioned well in tests, Mr. Cannon says. "It seems to go pretty smoothly if you get the fingerprint centered right." Those with concerns about personal privacy can elect to continue using passwords, he adds. The University of California at Santa Barbara recently installed an iris-scanning system for controlling access by about 500 people to a 10,000-square-foot "clean room" in a semiconductor-research center. In the past, having those people swipe their ID cards at the door would result in more work for staff members, who would have to replace lost or broken cards, says Jack Whaley, manager of the Nanofabrication Facility. Moreover, the card readers were sometimes balky, he says, and nothing prevented people from lending their cards to others. In the new system, an individual's eyes are photographed, and the images are digitized, encrypted, and stored on a computer server with information about what doors the individual is authorized to use and at what times. Researchers who want to get in simply step up to an iris reader, which transmits an image of the iris to the server. If the images match, the computer opens the door. Some challenges remain, like reminding people who have "droopy eyelids" to open their eyes wide, says Mr. Whaley. But the system, which cost between $20,000 and $30,000, has made a negligible number of errors. "It's pretty good," he says. More-exotic technology is on the horizon. Fujitsu Ltd. announced in June that the Chiba Institute of Technology, in Japan, has adopted a company device that uses infrared light to read the unique pattern of veins in a student's hand. The patterns are recorded on each individual's ID card. At kiosks on the campus, students can get access to their academic transcripts and other personal records by inserting the cards and holding their hand over a palm reader. Next year the institute, which has about 11,000 students, plans to issue similar cards to faculty and staff members. It is considering expanding the system for such purposes as tracking library checkouts and class attendance. Joel Hagberg, vice president for marketing and business development at Fujitsu Computer Products of America, says the company is discussing use of the technology with American colleges, which he does not identify. The system could start surfacing on American campuses early next year, he says. The vein scanner costs more than a fingerprint reader, which can run as much as $100, but less than an iris reader, he says, although he declines to provide specific figures. The technology will probably materialize first at a large research institution, most likely as part of a centralized service such as controlling college officials' access to student records, Mr. Hagberg predicts, noting that such an application would require only a few palm readers. "This is something that you will see coming to a university near you in the near future," he says. Privacy Concerns For all the efficiency and gee-whiz value of biometric technology, civil libertarians say it raises serious concerns about privacy. The theft or abuse of biometric measurements could be even more threatening than misuse of Social Security numbers, warns Mr. Tien, of the Electronic Frontier Foundation. Campus officials using fingerprint readers stress that their systems do not record individuals' fingerprints in images like those used by law-enforcement agencies. Rather, the systems produce a mathematical representation of fingerprints that would be useless to anyone outside the colleges. Hand-geometry systems seem to cause the least apprehension because such measurements are not commonly used off campus and so would have little or no application if the biometric data were to leak out. "The only person it does any good is me," says Mr. Beck, the Georgia student. Keene State College, in New Hampshire, moved to a hand-reader system this semester. Paul A. Striffolino, director of campus life, says the system does not intrude on the privacy of the college's 5,000 students. "An eye-scanning system would seem over the top to me," he says. But some observers say even hand-geometry data could be misused. If hand readers become commonplace, authorities could use records from the systems to reconstruct a student's movements and activities on the campus or across a broader area, says Mr. Tien. "It facilitates an atmosphere or a climate of checkpoints," he says. "All it is, is maybe a faster way to get through a door. We have to wonder whether these are the right trade-offs to be making." Indeed, records of a student's biometric measurements, as well as records of where and when that student used a biometric device, probably would be protected from public disclosure under the Family Educational Rights and Privacy Act, says Steven McDonald, general counsel at the Rhode Island School of Design, who tracks the effect of the federal law on the use of technology on campuses. In most cases, he says, Ferpa would not allow a college to disclose, without a student's permission, where and when that student had entered a dining hall, for example. But the records could still be used by the college's own staff and might be vulnerable to subpoena by law-enforcement officials, he says. Nancy Tribbensee, deputy general counsel at Arizona State, says a college should acknowledge privacy concerns before settling on biometric technology. She suggests that college officials consider whether the benefits, like tighter security, would be outweighed by ways in which the data could be abused. Recordings from the iris scanner at the university's Biodesign Institute are not covered by Ferpa, Ms. Tribbensee notes, because the system is used by faculty and staff members. But the university treats the data as personnel records and therefore as confidential, and it would fight any effort to obtain copies through the state's public-records law, she says. High Price Tag Privacy is not the only concern about biometric security systems. Some users also worry about safety -- for example, whether touching a hand reader could expose someone to colds and the flu from previous users. Mr. May, of New Hampshire, says the device is "no different than a doorknob." Still, liquid hand sanitizer is available at each hand reader, in a dispenser attached to the wall, and a staff member wipes the readers with a sanitizing solution every 15 minutes. Another hurdle facing biometric systems is cost. Last year Creighton University considered using fingerprint readers to control access to the 1,500 to 2,000 computers in its laboratories and offices. At $90 to $100 a pop, Creighton would have had to spend as much as $200,000 on the devices -- and that wouldn't have included the cost of upgrading the machines as technology advanced. "That would have been a huge expense," says Michael M. Allington, assistant director of student-technology support in the information-technology department. Creighton took a pass. Still, industry officials argue that biometric systems make financial sense for colleges, at least in some situations. The staff and systems needed to maintain a list of passwords for security systems might cost a college $50 per student annually, says Tom Doggett, director of marketing for Saflink Corporation, which makes a variety of biometric systems. By contrast, he says, a large college might spend $30 to $40 per student to deploy a biometric system. "You could make the case that the system would pay for itself in a year," Mr. Doggett says. But James L. Wayman, director of the National Biometric Test Center at San Jose State University, which explores technical issues related to the technology, is less optimistic. It is unclear, he says, whether dining halls are losing enough money from fraud to warrant the expense of a biometric system. "Will it pay?" he asks. "That's where it all falls apart." "Tell me again," he says, "why you need them on college campuses." Biometric systems can also have technical problems, which have prodded a few colleges to back away from the technology. Recently the New York State Center for Engineering Design and Industrial Innovation, at the State University of New York at Buffalo, encountered problems with a fingerprint-scanning system used to control access to its facilities. The readers worked well in 2000, when they were installed inside the building, says Kenneth W. English, deputy director. But the design center is planning an expansion that would require placing the access controls on the building's exterior, and the fingerprint readers worked poorly there because of snow and ice. So the center is reverting to having users swipe ID cards through a card reader. Mr. English hopes that improvements in biometric technology will allow the center to move back to fingerprint readers in the next two or three years. 'Weak Fingerprints' When Creighton considered fingerprint readers, it tested several models. But the machines had a hard time recognizing faculty members in the dental school, recalls Mr. Allington. They seemed to have less-visible fingerprints, probably because of the frequency with which they washed their hands, he says. A similar problem surfaced in Georgia's food-service department, where 600 employees use a fingerprint system to sign in and out of work. About 10 of them, whose work often keeps their hands submerged in water, have "weak fingerprints" and so cannot use the biometric system, says Christopher H. Wilkins, an information-technology manager in the university's food-service division. They still clock in and out by swiping an ID card or entering an ID number. _________________________________________________________________ Colloquy Transcript http://chronicle.com/colloquy/2005/12/bio/ Throwing Away the Keys Thursday, December 1, at 2 p.m., U.S. Eastern time The topic Forget keys and photo ID's. Students trying to get into dormitories at Johnson & Wales University in Denver must have their hands measured by an electronic scanner. Food-service workers at the University of Georgia punch in and out of their shifts with a time clock that scans their fingerprints. And faculty and staff members seeking weekend access to the Biodesign Institute at Arizona State University must be approved by a device that checks 240 points in the iris of the eye. More and more colleges are using such biometric technology, which its fans say is more secure and efficient than traditional tools. The technology also offers a new way to control access to campus computers and networks. But biometric systems can have technical problems, and they are expensive to install. And some observers worry that the systems could leave an electronic trail -- open to abuse or theft -- of employees' and students' activities. Are the advantages of biometric technology worth its high cost? Do they outweigh its potential misuses? Are biometric records protected from public disclosure under the Family Educational Rights and Privacy Act, or do colleges need to take extra steps to protect such data? The guest J. Michael Floyd is director of food services at the University of Georgia, which has used biometric technology in one form or another in its dining halls since 1974. _________________________________________________________________ A transcript of the chat follows. _________________________________________________________________ Vincent Kiernan (Moderator): Good afternoon, and welcome to Colloquy. I'm Vincent Kiernan, a senior writer at The Chronicle, and I will be moderating today's discussion about the use of biometrics in higher education. Our guest is J. Michael Floyd, director of food services at the University of Georgia. His institution is a pioneer in the use of biometrics -- Georgia has used hand readers in its dining halls since the 1970s. Just a quick reminder to everyone out there in cyberspace: Send in your questions and comments! Now, welcome, Mike. Could you start by giving us a thumbnail sketch of what your institution does in this area? _________________________________________________________________ J. Michael Floyd: The University of Georgia Food Services has utilized biometric technology since 1972 for access control for its voluntary meal plan program that allows unlimited access for its customers from 7 am to midnight daily. The department is presently on its third generation of hand image readers and has recently implemented a biometric timekeeping system for its 700 employees. The department has chosen biometric technology for its access control to prevent sharing of meal plans by customers, reduce labor cost for access control, and to increase speed of entry for its customers. The average customer gains access into our dining commons within a 3-5 second time period with the use of biometric technology. Presently 33,000 students here at the University utilize this technology for access for dining commmons, residence halls and campus recreation facilities. _________________________________________________________________ Vincent Kiernan (Moderator): Now onto our questions... _________________________________________________________________ Question from Terri Moreman, U.S. Olympic Training Center: Terri Moreman U.S. Olympic Training Center Colorado Springs, Colorado Advantages to Biometrics Easy to maintain and archive guest access (various reports available with the ability to customize) Quicker smother entry - especially when most students dont want to carry I.D. card. Cheaper and easier then re-keying access doors Less chance of misuse Card access is even higher however; here again the student would need to carry the card at all times. Without the card they have no access. Disadvantage Dont go with new technology out the start gate. Seek out a proven product in the marketplace. Initial equipment set-up is high however in the long run it pays for itself Hand geometry readers cost an average of $3,000 per location Certified technicians trained in this specialty are required to maintain, trouble shoot and make repairs. Generally speaking an electrician or layman may understand the electrical components; however he would lack the necessary knowledge to function in this capacity. The challenge is that technology changes and if you maintain a system too long its hard to find parts it. Routine upgrades in software and hardware need to be considered to maintain your system. Electronic access is great until you have a power outage. Systems normally reset themselves however; surges and losses in power can cause damage to your system. If your facility is in a high risk lightning area it would advantageous to secure a back up generator. J. Michael Floyd: Terri Moreman makes some excellent comments on her use of biometric handreaders at the US Olympic Training Center. One of the big advantages that we find in our application of biometrics here at the University of Georgia is the financial savings that we realize with this system. Let me explain this statement. In our application customers activate the system themselves by either swiping their id card or punching in their id number then placing their hand in the reader. Once the reader recognizes the hand image as a customer it then sends a signal to the turnstyle that allows the customer to enter the dining commons. By using this self activation system we do not need a cashier at every entry device, only a cashier to monitor all the entry devices for each dining commons. This reduces our labor cost by eight fulltime cashiers. This cost savings greatly outweighs the additional cost of the biometric readers. A disadvantage of the system is that it does require trained technicians to maintain the system, which a photo base only system normally does not require. The main service issue that we have is the routine replacement that we have to do on the keypad due to the large amount of usage our systems receive by our customers choosing to enter their student id number in lieu of swiping their id card. The numbers are actually worn off the keypad. _________________________________________________________________ Question from G. Buhl, Rutgers U.: WIth the loss and theft of personal data by Universities reported recently in the media, what are the risks to students and faculty of entrusting biometric data to Universities? J. Michael Floyd: With any systems the appropriate safeguards must be in place to protect data. However, the biometric data that we use is hand & finger images and not prints. This data is of no value to an outsider to identify a customer by a hand or finger image. The key to our system is that we do not store finger or hand prints. In addition we do not identify our customers or employees by their social security number in our systems, but we utilize University identification numbers instead. _________________________________________________________________ Question from Vincent Kiernan: Mike, a big issue with any new IT system is cost. Can you give us an idea of how much this system costs Georgia -- and how much it saves you in operational costs? J. Michael Floyd: The cost of any system is reflective of the size of the application, number of hand readers and the number of locations. In our case the initial cost was approximately $100,000. But this cost was immediately offset by reduction of staffing. With the use of biometric readers where the customer activates the system you do not need a cashier for every entry device. In our case we are able to staff our cashier station with one cashier who monitors two hand readers. This alone reduced labor by 8 fulltime positions. In today's dollars this is a savings of approximately $186,000 in salary and benefits cost every year. But the true savings is the speed of access for our customers. Thereby allowing greater thru put of customers in dining centers, which allows us to maximize our operations and reduces the need to build operations for peak customer periods. In our case we provide meal plan service for our customers in four dining centers. On some other campuses this same number of customers may need five to six dining centers. _________________________________________________________________ Question from Vincent Kiernan: Mike, biometrics make some people nervous from a privacy perspective. Have you encountered any concern on your campus? How do you reassure people that their privacy is being protected? J. Michael Floyd: We have not experienced the privacy concern from our customers because we take an aggressive approach of educating our customers that our system is a hand image and not a hand print. One of the ways we educate our customers on the system is including this information in our Food Service presentation during the summer Freshman Orientation program. In addition we have previous articles from the Wall Street Journal and New York Times framed and in our lobbies to educate our customers on our biometric application. Our biometric system was also featured in "Beyond 2000" on the Discovery Channel several years ago and when the film crew was on campus we attempted to get as many of our students involved with the filming. In addition, during my 20 year tenure here at the University I have never had a customer express concern on this issue. What I do encounter from our customers is a sense of pride that they are using state of the art technology and I find they are normally our best PR agents as they love to explain our system to visitors. _________________________________________________________________ Question from Vincent Kiernan: Do you have any plans to further expand your use of biometrics in the dining hall system? J. Michael Floyd: Yes. We have recently expanded the use of biometrics for timekeeping for employees. Utilizing a different biometric system, our employees clock in & out daily using a finger image. The next expansion is to utilize these devices for backdoor employee access into our operations. This will increase the overall security of our operations, especially since we have operations open till midnight and our plans include a 24-hour dining center in the near future. In my opinion, the real future of biometrics in the workplace is in timekeeping. This application for employers with large work forces will greatly increase the accuracy of paying for actual hours worked and prevent "buddy punching." _________________________________________________________________ Question from Edward Marshall, University of Pennsylvania: Are you aware of any health related issues resulting from the use of biometric technologies? In particular, retinal scans. J. Michael Floyd: No, there is no greater risk with the hand image readers than the doorknob on the front of the building. However, we do have a procedure in place to sanitize the hand reader surface on a routine schedule thru out the day. In addition we have hand sanitizer stations located inside our dining operations for customers who would like to use this product. We do not utilize retinal scans here. However, the most common form of eye scanning is iris scanning and with these devices the eye is typically 10 to 14 inches away from the scanner. _________________________________________________________________ Vincent Kiernan (Moderator): We're about half way through our scheduled time for this conversation. If you have any questions for Mr. Floyd, now would be a great time to send them in. _________________________________________________________________ Question from Dick Sigelko, Michigan State University: If the system is not storing fingerprints or hand geography, how does it identify the individual as having the privilege? J. Michael Floyd: The system is storing hand and finger image templates. The templates are a mathematical representation of the hand or finger ridges. These stored templates are then compared to the image presented by the customer/employee when they place their hand or finger in the reader. All verifications are done on a one to one comparison, not a one to many comparison. For example the customer will input their ID number by scanning their card or typing their card number on a keypad and then they place their hand in the reader. The customer / employee must be active in the system prior to utilizing the system. _________________________________________________________________ Question from Matt Miller, Gettysburg College: How long on average does it take to add a new hand image to the system? J. Michael Floyd: For both systems the initial image is captured at an orientation. Each image takes approximately 30 seconds to capture and verify the first time. However, with our meal plan system this one time enrollment is the only time we must physically see the student to begin participation in the meal plan for their entire academic stay at UGA. The enrollment for students is done when they have their ID card produced. _________________________________________________________________ Question from Vincent Kiernan: What advice do you have for colleges that might consider hand scanning in the future? Are there any particular land mines to avoid? J. Michael Floyd: The key is to promote this as state of art technology and to excite the customers that they are involved in a unique application of technology. One installation issue to avoid is to make sure that all hand image readers are installed at the same height. Readers installed at different height can result in a higher error ratio. _________________________________________________________________ Question from Dick Sigelko, Michigan State University: Have students expressed a concern about contamination, germs or the "ick" factor? J. Michael Floyd: Over the years we have heard this question from a few customers, which allows us to explain our system and how we sanitize the reader surface. But normally when we share the comparison about the front doorknob on the building the student then realizes the enormous number of common surfaces they touch with their hands each day. _________________________________________________________________ Question from Dick Sigelko, Michigan State University: How many mis-reads per 100 do you get? J. Michael Floyd: We are at less than 1% of false-negatives. This allows our Cashier to then look up the customer in our data base and then permit the customer to dine. _________________________________________________________________ Question from Francine Reynolds, University of Richmond: Mike, what systems are your biometric readers interfacing with (i.e. CBORD's CSGold, etc.) J. Michael Floyd: Our system is a proprietary system that our campus IT department developed and maintains for the campus. _________________________________________________________________ Question from Terri Moreman, U.S. Olympic Training Center: Mike, is your system tied to dorm room or buliding access? J. Michael Floyd: Yes, our system is tied to residence hall building access. But not individual rooms. _________________________________________________________________ Question from Rich Bredahl, University of Texas at Austin: How about issues of cleaniness? With potentially several hundred people using a reader per hour, how do you: 1) Keep the reader clean 2) Ensure the reader does not become a means of passing germs/bacteria/viruses J. Michael Floyd: No, there is no greater risk with the hand image readers than the doorknob on the front of the building. However, we do have a procedure in place to sanitize the hand reader surface on a routine schedule throughout the day. In addition we have hand sanitizer stations located inside our dining operations for customers who would like to use this product. _________________________________________________________________ Question from Vincent Kiernan: That will be our last question. Mike, any final thoughts? J. Michael Floyd: In conclusion, the key benefit of a biometric system is that it can be a user activated system that creates a great deal of ownership by the customer. With this ownership, there is a buy in from the customer to assist the organization in making the system work. Additionally, biometric systems have the potential of reducing personnel cost and improving overall levels of security and customer thru put. There is also a greater awareness of security by the customer than the traditional photo base system. Biometrics is the technology that our children will see in their future workplace. _________________________________________________________________ Vincent Kiernan (Moderator): That about does it for today. On behalf of The Chronicle, thanks to Mike Floyd and his staff for their illuminating answers to the questions, and thanks to all of you for participating. Have a good afternoon. _________________________________________________________________ J. Michael Floyd: A special thank you to Donald Smith, Department Manager of UGAcard Support Services and Chris Wilkins, IT Manager, UGA Food Services for joining me today on the Colloquy and assisting with the responses.Additionally Biometric systems have the potential of reducing personnel cost and improving overall levels of security and customer thru put. ------------------------ Yahoo!

The baseband has 'lawful intercept' built in to appease western governments, at least.

For an example of the details, the osmocombb project, http://bb.osmocom.org/trac/, is trying to write a completely free baseband stack for cell phones. They have some pretty good details and presentations on the hardware hacking involved in re-writing the baseband from scratch. As for actually secure phones, from the baseband through the user interface, Cryptophone, http://www.cryptophone.de/, makes a few models, but as you can expect, they are expensive. There are probably others, but I've only used the cryptophone g10+ model.

Show Your Hand, Not Your ID The Chronicle of Higher Education, 5.12.2 http://chronicle.com/free/v52/i15/15a02801.htm [Colloquy transcript appended.] [Yes, I can see the advantages of using these scanners, and I think the concerns over theft and privacy issues are reasonably countered. But the real problem is that, in making such identifications mandatory, the informal and generally harmless violations of rules are no longer possible. Suppose a researcher wants to sneak a friend into his lab after hours. This, and many, many other technical violations will no longer be allowed. We must be ever vigilant about this kind of "unreasonableness of reason," to almost coin a meme. There is a single hit on Google! I lack a better term.] Colleges use biometric scanners to screen for access to dining halls, labs, dorms, gyms, and computer networks By VINCENT KIERNAN At many colleges, students flash a photo ID at a food-service worker to get into a dining hall. Things work differently at the University of Georgia, where Gavin Beck, a senior, places his hand on a sensor that determines if the person waiting to eat really is Gavin Beck. The process, which measures the size and shape of the hand, takes only a few seconds. "No system is foolproof, but this is far more efficient for us than a photo-based system," says J. Michael Floyd, director of food services at Georgia. The university is among the first to use the biometric technology widely, having relied on it in one form or another in its dining halls since 1974. Hand scanners, electronic fingerprint readers, even retina scanners are not just for super-spies in Hollywood movies anymore. The technology is increasingly being used by colleges to allow students, professors, and staff members to gain access to dining halls, laboratories, gyms, and other facilities on their campuses. Improvements in the technology are spurring greater interest among some college administrators. Faculty and staff members who seek weekend access to the Biodesign Institute at Arizona State University, for example, must be approved by a device that checks 240 points in the iris of the eye. Locks on dormitory doors at Johnson & Wales University at Denver are controlled by a hand-geometry reader similar to Georgia's. Food-service workers at Georgia punch in and out of their shifts with a time clock that scans their fingerprints so that a worker cannot clock in for an absent friend. Proponents say biometric technology offers increased security and efficiency, making lines move faster while keeping unauthorized visitors out. And at a time when colleges are trying to safeguard campus data, the technology offers colleges a new tool to control access to computers and networks. But cost and various technical obstacles are likely to slow the technology's adoption by colleges. And some observers worry that the systems could leave an electronic paper trail -- open to abuse or theft -- of the activities of students and faculty and staff members. "It's an extremely disturbing trend," says Lee Tien, a senior staff lawyer at the Electronic Frontier Foundation, a group that promotes online civil liberties. "Biometrics is a technology that is dangerous for privacy." How It Works Administrators who support the use of biometric technology say scanning body parts is far more secure than asking users for passwords, which can be forgotten or stolen. The scanning devices look for some unique characteristic of the user, such as the arrangement of ridges on the finger, the pattern of blood vessels in the eye, or the size and shape of the hand. The characteristic -- called a biometric measurement -- must be unique for each individual, must not change, and must be easily measured. Typically a person's hand, fingerprint, or eyeball is measured once when he or she is enrolled in the system, and that measurement is stored in a computer database or on a smart ID card. At the entrance to a controlled area, such as a dining hall, the individual's characteristic is measured again and compared with the original recording. If the two measurements match, the person is admitted. Georgia's early system recorded two-dimensional measurements of users' hands. But in 1995, as part of a campuswide move toward biometric identification, the system was upgraded to one that takes three-dimensional measurements. Now the 32,500 students use their hands as passports to all-you-can-eat meal plans, the recreation center, and dormitories. They either swipe an ID card through a card reader or enter an ID number on a keypad before presenting their hand for scanning. Mr. Floyd, the food-service director, says the system rarely misidentifies anyone. Mr. Beck, the Georgia senior, recalls only one glitch, when the system wouldn't recognize him at the start of fall semester, probably because of a subtle change in his hand's shape over the summer. At a nearby office, he showed his ID, had his hand rescanned, and was cleared to eat his meal. "It set me back a couple of minutes," he says, "but it was no big deal." The University of New Hampshire installed a hand-reading system in its dining halls when campus officials wanted to halt the sharing of all-you-can-eat meal plans by several people, says David J. May, executive director of hospitality services. "It really has worked wonderfully for us," he says. Although he cannot estimate the amount of fraud that the system has stopped, he is convinced that "students would beat the system if we were using ID cards." The cost of putting biometric security in place is not exorbitant, says Mr. May. Each hand reader costs about $2,500, and the turnstile to which it is connected costs $8,500 to $9,000. The 12,000-student university has seven biometric stations at its dining halls, he says. Recently, New Hampshire expanded the system to control employees' access to one of its dining halls. That way the university will not have to issue keys to employees -- or replace locks if keys are stolen. "If an employee leaves, we just take them out of the database," so the hand-reading system will no longer recognize that person, says Mr. May. Smaller-Scale Projects Biometric systems are also being used on a smaller scale on some campuses. At Rutgers University at New Brunswick, fingerprint-scanning devices are being installed on computers attached to laboratory equipment in the materials-science department. The department, with some 80 potential users of the technology, has a password system to track usage of the equipment, so that the appropriate research grant is charged. But some students complained that they were being charged for others' use, says W. Roger Cannon, a professor of materials science and engineering. That prompted him to investigate a biometric alternative. "If we had a fingerprint system, there would be no argument," he says. The new system has functioned well in tests, Mr. Cannon says. "It seems to go pretty smoothly if you get the fingerprint centered right." Those with concerns about personal privacy can elect to continue using passwords, he adds. The University of California at Santa Barbara recently installed an iris-scanning system for controlling access by about 500 people to a 10,000-square-foot "clean room" in a semiconductor-research center. In the past, having those people swipe their ID cards at the door would result in more work for staff members, who would have to replace lost or broken cards, says Jack Whaley, manager of the Nanofabrication Facility. Moreover, the card readers were sometimes balky, he says, and nothing prevented people from lending their cards to others. In the new system, an individual's eyes are photographed, and the images are digitized, encrypted, and stored on a computer server with information about what doors the individual is authorized to use and at what times. Researchers who want to get in simply step up to an iris reader, which transmits an image of the iris to the server. If the images match, the computer opens the door. Some challenges remain, like reminding people who have "droopy eyelids" to open their eyes wide, says Mr. Whaley. But the system, which cost between $20,000 and $30,000, has made a negligible number of errors. "It's pretty good," he says. More-exotic technology is on the horizon. Fujitsu Ltd. announced in June that the Chiba Institute of Technology, in Japan, has adopted a company device that uses infrared light to read the unique pattern of veins in a student's hand. The patterns are recorded on each individual's ID card. At kiosks on the campus, students can get access to their academic transcripts and other personal records by inserting the cards and holding their hand over a palm reader. Next year the institute, which has about 11,000 students, plans to issue similar cards to faculty and staff members. It is considering expanding the system for such purposes as tracking library checkouts and class attendance. Joel Hagberg, vice president for marketing and business development at Fujitsu Computer Products of America, says the company is discussing use of the technology with American colleges, which he does not identify. The system could start surfacing on American campuses early next year, he says. The vein scanner costs more than a fingerprint reader, which can run as much as $100, but less than an iris reader, he says, although he declines to provide specific figures. The technology will probably materialize first at a large research institution, most likely as part of a centralized service such as controlling college officials' access to student records, Mr. Hagberg predicts, noting that such an application would require only a few palm readers. "This is something that you will see coming to a university near you in the near future," he says. Privacy Concerns For all the efficiency and gee-whiz value of biometric technology, civil libertarians say it raises serious concerns about privacy. The theft or abuse of biometric measurements could be even more threatening than misuse of Social Security numbers, warns Mr. Tien, of the Electronic Frontier Foundation. Campus officials using fingerprint readers stress that their systems do not record individuals' fingerprints in images like those used by law-enforcement agencies. Rather, the systems produce a mathematical representation of fingerprints that would be useless to anyone outside the colleges. Hand-geometry systems seem to cause the least apprehension because such measurements are not commonly used off campus and so would have little or no application if the biometric data were to leak out. "The only person it does any good is me," says Mr. Beck, the Georgia student. Keene State College, in New Hampshire, moved to a hand-reader system this semester. Paul A. Striffolino, director of campus life, says the system does not intrude on the privacy of the college's 5,000 students. "An eye-scanning system would seem over the top to me," he says. But some observers say even hand-geometry data could be misused. If hand readers become commonplace, authorities could use records from the systems to reconstruct a student's movements and activities on the campus or across a broader area, says Mr. Tien. "It facilitates an atmosphere or a climate of checkpoints," he says. "All it is, is maybe a faster way to get through a door. We have to wonder whether these are the right trade-offs to be making." Indeed, records of a student's biometric measurements, as well as records of where and when that student used a biometric device, probably would be protected from public disclosure under the Family Educational Rights and Privacy Act, says Steven McDonald, general counsel at the Rhode Island School of Design, who tracks the effect of the federal law on the use of technology on campuses. In most cases, he says, Ferpa would not allow a college to disclose, without a student's permission, where and when that student had entered a dining hall, for example. But the records could still be used by the college's own staff and might be vulnerable to subpoena by law-enforcement officials, he says. Nancy Tribbensee, deputy general counsel at Arizona State, says a college should acknowledge privacy concerns before settling on biometric technology. She suggests that college officials consider whether the benefits, like tighter security, would be outweighed by ways in which the data could be abused. Recordings from the iris scanner at the university's Biodesign Institute are not covered by Ferpa, Ms. Tribbensee notes, because the system is used by faculty and staff members. But the university treats the data as personnel records and therefore as confidential, and it would fight any effort to obtain copies through the state's public-records law, she says. High Price Tag Privacy is not the only concern about biometric security systems. Some users also worry about safety -- for example, whether touching a hand reader could expose someone to colds and the flu from previous users. Mr. May, of New Hampshire, says the device is "no different than a doorknob." Still, liquid hand sanitizer is available at each hand reader, in a dispenser attached to the wall, and a staff member wipes the readers with a sanitizing solution every 15 minutes. Another hurdle facing biometric systems is cost. Last year Creighton University considered using fingerprint readers to control access to the 1,500 to 2,000 computers in its laboratories and offices. At $90 to $100 a pop, Creighton would have had to spend as much as $200,000 on the devices -- and that wouldn't have included the cost of upgrading the machines as technology advanced. "That would have been a huge expense," says Michael M. Allington, assistant director of student-technology support in the information-technology department. Creighton took a pass. Still, industry officials argue that biometric systems make financial sense for colleges, at least in some situations. The staff and systems needed to maintain a list of passwords for security systems might cost a college $50 per student annually, says Tom Doggett, director of marketing for Saflink Corporation, which makes a variety of biometric systems. By contrast, he says, a large college might spend $30 to $40 per student to deploy a biometric system. "You could make the case that the system would pay for itself in a year," Mr. Doggett says. But James L. Wayman, director of the National Biometric Test Center at San Jose State University, which explores technical issues related to the technology, is less optimistic. It is unclear, he says, whether dining halls are losing enough money from fraud to warrant the expense of a biometric system. "Will it pay?" he asks. "That's where it all falls apart." "Tell me again," he says, "why you need them on college campuses." Biometric systems can also have technical problems, which have prodded a few colleges to back away from the technology. Recently the New York State Center for Engineering Design and Industrial Innovation, at the State University of New York at Buffalo, encountered problems with a fingerprint-scanning system used to control access to its facilities. The readers worked well in 2000, when they were installed inside the building, says Kenneth W. English, deputy director. But the design center is planning an expansion that would require placing the access controls on the building's exterior, and the fingerprint readers worked poorly there because of snow and ice. So the center is reverting to having users swipe ID cards through a card reader. Mr. English hopes that improvements in biometric technology will allow the center to move back to fingerprint readers in the next two or three years. 'Weak Fingerprints' When Creighton considered fingerprint readers, it tested several models. But the machines had a hard time recognizing faculty members in the dental school, recalls Mr. Allington. They seemed to have less-visible fingerprints, probably because of the frequency with which they washed their hands, he says. A similar problem surfaced in Georgia's food-service department, where 600 employees use a fingerprint system to sign in and out of work. About 10 of them, whose work often keeps their hands submerged in water, have "weak fingerprints" and so cannot use the biometric system, says Christopher H. Wilkins, an information-technology manager in the university's food-service division. They still clock in and out by swiping an ID card or entering an ID number. _________________________________________________________________ Colloquy Transcript http://chronicle.com/colloquy/2005/12/bio/ Throwing Away the Keys Thursday, December 1, at 2 p.m., U.S. Eastern time The topic Forget keys and photo ID's.

Are the advantages of biometric technology worth its high cost? Do they outweigh its potential misuses? Are biometric records protected from public disclosure under the Family Educational Rights and Privacy Act, or do colleges need to take extra steps to protect such data? The guest J. Michael Floyd is director of food services at the University of Georgia, which has used biometric technology in one form or another in its dining halls since 1974. _________________________________________________________________ A transcript of the chat follows. _________________________________________________________________ Vincent Kiernan (Moderator): Good afternoon, and welcome to Colloquy. I'm Vincent Kiernan, a senior writer at The Chronicle, and I will be moderating today's discussion about the use of biometrics in higher education. Our guest is J. Michael Floyd, director of food services at the University of Georgia. His institution is a pioneer in the use of biometrics -- Georgia has used hand readers in its dining halls since the 1970s. Just a quick reminder to everyone out there in cyberspace: Send in your questions and comments! Now, welcome, Mike. Could you start by giving us a thumbnail sketch of what your institution does in this area? _________________________________________________________________ J. Michael Floyd: The University of Georgia Food Services has utilized biometric technology since 1972 for access control for its voluntary meal plan program that allows unlimited access for its customers from 7 am to midnight daily. The department is presently on its third generation of hand image readers and has recently implemented a biometric timekeeping system for its 700 employees. The department has chosen biometric technology for its access control to prevent sharing of meal plans by customers, reduce labor cost for access control, and to increase speed of entry for its customers. The average customer gains access into our dining commons within a 3-5 second time period with the use of biometric technology. Presently 33,000 students here at the University utilize this technology for access for dining commmons, residence halls and campus recreation facilities. _________________________________________________________________ Vincent Kiernan (Moderator): Now onto our questions... _________________________________________________________________ Question from Terri Moreman, U.S. Olympic Training Center: Terri Moreman U.S. Olympic Training Center Colorado Springs, Colorado Advantages to Biometrics Easy to maintain and archive guest access (various reports available with the ability to customize) Quicker smother entry - especially when most students dont want to carry I.D. card. Cheaper and easier then re-keying access doors Less chance of misuse Card access is even higher however; here again the student would need to carry the card at all times. Without the card they have no access. Disadvantage Dont go with new technology out the start gate. Seek out a proven product in the marketplace. Initial equipment set-up is high however in the long run it pays for itself Hand geometry readers cost an average of $3,000 per location Certified technicians trained in this specialty are required to maintain, trouble shoot and make repairs. Generally speaking an electrician or layman may understand the electrical components; however he would lack the necessary knowledge to function in this capacity. The challenge is that technology changes and if you maintain a system too long its hard to find parts it. Routine upgrades in software and hardware need to be considered to maintain your system. Electronic access is great until you have a power outage. Systems normally reset themselves however; surges and losses in power can cause damage to your system. If your facility is in a high risk lightning area it would advantageous to secure a back up generator. J. Michael Floyd: Terri Moreman makes some excellent comments on her use of biometric handreaders at the US Olympic Training Center. One of the big advantages that we find in our application of biometrics here at the University of Georgia is the financial savings that we realize with this system. Let me explain this statement. In our application customers activate the system themselves by either swiping their id card or punching in their id number then placing their hand in the reader. Once the reader recognizes the hand image as a customer it then sends a signal to the turnstyle that allows the customer to enter the dining commons. By using this self activation system we do not need a cashier at every entry device, only a cashier to monitor all the entry devices for each dining commons. This reduces our labor cost by eight fulltime cashiers. This cost savings greatly outweighs the additional cost of the biometric readers. A disadvantage of the system is that it does require trained technicians to maintain the system, which a photo base only system normally does not require. The main service issue that we have is the routine replacement that we have to do on the keypad due to the large amount of usage our systems receive by our customers choosing to enter their student id number in lieu of swiping their id card. The numbers are actually worn off the keypad. _________________________________________________________________ Question from G. Buhl, Rutgers U.: WIth the loss and theft of personal data by Universities reported recently in the media, what are the risks to students and faculty of entrusting biometric data to Universities? J. Michael Floyd: With any systems the appropriate safeguards must be in place to protect data. However, the biometric data that we use is hand & finger images and not prints. This data is of no value to an outsider to identify a customer by a hand or finger image. The key to our system is that we do not store finger or hand prints. In addition we do not identify our customers or employees by their social security number in our systems, but we utilize University identification numbers instead. _________________________________________________________________ Question from Vincent Kiernan: Mike, a big issue with any new IT system is cost. Can you give us an idea of how much this system costs Georgia -- and how much it saves you in operational costs? J. Michael Floyd: The cost of any system is reflective of the size of the application, number of hand readers and the number of locations. In our case the initial cost was approximately $100,000. But this cost was immediately offset by reduction of staffing. With the use of biometric readers where the customer activates the system you do not need a cashier for every entry device. In our case we are able to staff our cashier station with one cashier who monitors two hand readers. This alone reduced labor by 8 fulltime positions. In today's dollars this is a savings of approximately $186,000 in salary and benefits cost every year. But the true savings is the speed of access for our customers. Thereby allowing greater thru put of customers in dining centers, which allows us to maximize our operations and reduces the need to build operations for peak customer periods. In our case we provide meal plan service for our customers in four dining centers. On some other campuses this same number of customers may need five to six dining centers. _________________________________________________________________ Question from Vincent Kiernan: Mike, biometrics make some people nervous from a privacy perspective. Have you encountered any concern on your campus? How do you reassure people that their privacy is being protected? J. Michael Floyd: We have not experienced the privacy concern from our customers because we take an aggressive approach of educating our customers that our system is a hand image and not a hand print. One of the ways we educate our customers on the system is including this information in our Food Service presentation during the summer Freshman Orientation program. In addition we have previous articles from the Wall Street Journal and New York Times framed and in our lobbies to educate our customers on our biometric application. Our biometric system was also featured in "Beyond 2000" on the Discovery Channel several years ago and when the film crew was on campus we attempted to get as many of our students involved with the filming. In addition, during my 20 year tenure here at the University I have never had a customer express concern on this issue. What I do encounter from our customers is a sense of pride that they are using state of the art technology and I find they are normally our best PR agents as they love to explain our system to visitors. _________________________________________________________________ Question from Vincent Kiernan: Do you have any plans to further expand your use of biometrics in the dining hall system? J. Michael Floyd: Yes. We have recently expanded the use of biometrics for timekeeping for employees. Utilizing a different biometric system, our employees clock in & out daily using a finger image. The next expansion is to utilize these devices for backdoor employee access into our operations. This will increase the overall security of our operations, especially since we have operations open till midnight and our plans include a 24-hour dining center in the near future. In my opinion, the real future of biometrics in the workplace is in timekeeping. This application for employers with large work forces will greatly increase the accuracy of paying for actual hours worked and prevent "buddy punching." _________________________________________________________________ Question from Edward Marshall, University of Pennsylvania: Are you aware of any health related issues resulting from the use of biometric technologies? In particular, retinal scans. J. Michael Floyd: No, there is no greater risk with the hand image readers than the doorknob on the front of the building. However, we do have a procedure in place to sanitize the hand reader surface on a routine schedule thru out the day. In addition we have hand sanitizer stations located inside our dining operations for customers who would like to use this product. We do not utilize retinal scans here. However, the most common form of eye scanning is iris scanning and with these devices the eye is typically 10 to 14 inches away from the scanner. _________________________________________________________________ Vincent Kiernan (Moderator): We're about half way through our scheduled time for this conversation. If you have any questions for Mr. Floyd, now would be a great time to send them in. _________________________________________________________________ Question from Dick Sigelko, Michigan State University: If the system is not storing fingerprints or hand geography, how does it identify the individual as having the privilege? J. Michael Floyd: The system is storing hand and finger image templates. The templates are a mathematical representation of the hand or finger ridges. These stored templates are then compared to the image presented by the customer/employee when they place their hand or finger in the reader. All verifications are done on a one to one comparison, not a one to many comparison. For example the customer will input their ID number by scanning their card or typing their card number on a keypad and then they place their hand in the reader. The customer / employee must be active in the system prior to utilizing the system. _________________________________________________________________ Question from Matt Miller, Gettysburg College: How long on average does it take to add a new hand image to the system? J. Michael Floyd: For both systems the initial image is captured at an orientation. Each image takes approximately 30 seconds to capture and verify the first time. However, with our meal plan system this one time enrollment is the only time we must physically see the student to begin participation in the meal plan for their entire academic stay at UGA. The enrollment for students is done when they have their ID card produced. _________________________________________________________________ Question from Vincent Kiernan: What advice do you have for colleges that might consider hand scanning in the future? Are there any particular land mines to avoid? J. Michael Floyd: The key is to promote this as state of art technology and to excite the customers that they are involved in a unique application of technology. One installation issue to avoid is to make sure that all hand image readers are installed at the same height. Readers installed at different height can result in a higher error ratio. _________________________________________________________________ Question from Dick Sigelko, Michigan State University: Have students expressed a concern about contamination, germs or the "ick" factor? J. Michael Floyd: Over the years we have heard this question from a few customers, which allows us to explain our system and how we sanitize the reader surface. But normally when we share the comparison about the front doorknob on the building the student then realizes the enormous number of common surfaces they touch with their hands each day. _________________________________________________________________ Question from Dick Sigelko, Michigan State University: How many mis-reads per 100 do you get? J. Michael Floyd: We are at less than 1% of false-negatives. This allows our Cashier to then look up the customer in our data base and then permit the customer to dine. _________________________________________________________________ Question from Francine Reynolds, University of Richmond: Mike, what systems are your biometric readers interfacing with (i.e. CBORD's CSGold, etc.) J. Michael Floyd: Our system is a proprietary system that our campus IT department developed and maintains for the campus. _________________________________________________________________ Question from Terri Moreman, U.S. Olympic Training Center: Mike, is your system tied to dorm room or buliding access? J. Michael Floyd: Yes, our system is tied to residence hall building access. But not individual rooms. _________________________________________________________________ Question from Rich Bredahl, University of Texas at Austin: How about issues of cleaniness? With potentially several hundred people using a reader per hour, how do you: 1) Keep the reader clean 2) Ensure the reader does not become a means of passing germs/bacteria/viruses J. Michael Floyd: No, there is no greater risk with the hand image readers than the doorknob on the front of the building. However, we do have a procedure in place to sanitize the hand reader surface on a routine schedule throughout the day. In addition we have hand sanitizer stations located inside our dining operations for customers who would like to use this product. _________________________________________________________________ Question from Vincent Kiernan: That will be our last question. Mike, any final thoughts? J. Michael Floyd: In conclusion, the key benefit of a biometric system is that it can be a user activated system that creates a great deal of ownership by the customer. With this ownership, there is a buy in from the customer to assist the organization in making the system work. Additionally, biometric systems have the potential of reducing personnel cost and improving overall levels of security and customer thru put. There is also a greater awareness of security by the customer than the traditional photo base system. Biometrics is the technology that our children will see in their future workplace. _________________________________________________________________ Vincent Kiernan (Moderator): That about does it for today.

It seems like : the numbers are dwindling, and the user-end side of things is : becoming more uneasy. Roughly zero if your threat model involves a government. All cell phones have two operating systems, one is the baseband for managing communications with the cell towers and signal processing, the other is the one for the humans. The baseband has 'lawful intercept' built in to appease western governments, at least. I'm not sure to which OS the slashdot story refers, but here's a crash course in iphone's OSes, http://www.ihackintosh.com/2009/07/difference-between-iphone-baseband-bootl…. And here's a quick presentation on what the baseband OS, or firmware, does in a 3G phone, http://bwrc.eecs.berkeley.edu/seminars/Seminars_Archive/Sriram-9.15.00/3G_C…. For an example of the details, the osmocombb project, http://bb.osmocom.org/trac/, is trying to write a completely free baseband stack for cell phones. They have some pretty good details and presentations on the hardware hacking involved in re-writing the baseband from scratch. As for actually secure phones, from the baseband through the user interface, Cryptophone, http://www.cryptophone.de/, makes a few models, but as you can expect, they are expensive. There are probably others, but I've only used the cryptophone g10+ model. And just in case you think the baseband isn't fun to explore and exploit to win contests at security conferences, https://www.readwriteweb.com/archives/baseband_hacking_a_new_frontier_for_s… -- Andrew http://tpo.is/contact pgp 0x74ED336B _______________________________________________ liberationtech mailing list liberationtech(a)lists.stanford.edu Should you need to change your subscription options, please go to: https://mailman.stanford.edu/mailman/listinfo/liberationtech If you would like to receive a daily digest, click "yes" (once you click above) next to "would you like to receive list mail batched in a daily digest?"

YouTube (Dec 5) - "SIGKILL imminent [SIGINT09]" by CCCen: http://www.youtube.com/watch?v=MDgq5-RW2jw This is a talk from the SIGINT 2009 event (Cologne, Germany: May 22, 2009) by Astera and George Shammas. http://events.ccc.de/sigint/2009/Fahrplan/events/3166.en.html http://astera.soup.io/ http://wiki.nycresistor.com/wiki/User:Georgyo A survey of the road to killer robots + more. Pretty remarkable collection of information. Was just posted to the English-language YouTube channel of the venerable Chaos Computer Club: http://www.youtube.com/user/CCCen Here's the video they start off the talk with, an old Saturday Night Live skit featuring Sam Waterston pitching Old Glory Insurance's killer robot plan: http://www.nbc.com/saturday-night-live/video/old-glory-insurance/229049/ And here's the mentioned Boston Dynamics Big Dog Beta video, which at 4.7M views I was a little disappointed I had not seen it before :) http://www.youtube.com/watch?v=VXJZVZFRFJc ~22:25 - Spends a little time on iRobot, which is interesting considering their co-Founder was in the news a few days ago: http://www.wired.com/dangerroom/2012/12/cyphy/ gf -- Gregory Foster || gfoster(a)entersection.org @gregoryfoster <> http://entersection.com/ _______________________________________________ drone-list mailing list drone-list(a)lists.stanford.edu Should you need to change your subscription options, please go to: https://mailman.stanford.edu/mailman/listinfo/drone-list If you would like to receive a daily digest, click "yes" (once you click above) next to "would you like to receive list mail batched in a daily digest?"
