Fingernails store personal information

At least, here you don't have to lose a whole digit if your biometrics is compromised. http://optics.org/articles/news/11/7/4 Fingernails store personal information 6 July 2005 Japanese researchers are using femtosecond laser pulses to write data into human fingernails. Secure optical data storage could soon literally be at your fingertips thanks to work being carried out in Japan. Yoshio Hayasaki and his colleagues have discovered that data can be written into a human fingernail by irradiating it with femtosecond laser pulses. Capacities are said to be up to 5 mega bits and the stored data lasts for 6 months - the length of time it takes a fingernail to be completely replaced. (Optics Express 13 4560) Fingernail storage "I don't like carrying around a large number of cards, money and papers," Hayasaki from Tokushima University told Optics.org. "I think that a key application will be personal authentication. Data stored in a fingernail can be used with biometrics, such as fingerprint authentication and intravenous authentication of the finger." The team's approach is simple: use a femtosecond laser system to write the data into the nail and a fluorescence microscope to read it out. The key to reading the data out is that the nail's fluorescence increases at the point irradiated by the femtosecond pulses. Initial experiments were carried out on a small piece of human fingernail measuring 2 x 2 x 0.4 mm3. The writing system comprises a Ti:Sapphire oscillator and Ti: Sapphire amplifier. Pulses of less than 100 fs at 800 nm are then passed through a microscope and focused to three set depths (40, 60 and 80 microns) using an objective lens. Each "bit" of information has a diameter of 3.1 microns and is written by a single femtosecond pulse. A motorised stage moves the nail to create a bit spacing of 5 microns across the nail and a depth of 20 microns between recording layers. An optical microscope containing a filtered xenon arc lamp excites the fluorescence and reads out the data stored at the various depths. "We regulate the focus with the movement of the microscope objective," explained Hayasaki. "The distance between the planes is set to prevent cross-talk between data stored at different depths." Hayasaki adds that the same fluorescence signal is seen 172 days after recording. Although the initial experiments have concentrated on small pieces of nail, the team is now developing a system that can write data to a fingernail which is still attached to a finger. "We will develop a femtosecond laser processing system that can record the data at the desired points with compensation for the movement of a finger," said Hayasaki.

Fine, I'll just order the birth certificate and get it over with, right? Wrong. New York wants affirmative proof of identity for a copy now: passport or your [missing] original birth certificate. Anyone else see a circular problem here? http://www.health.state.ny.us/vital_records/birth.htm Identification Requirements - application must be submitted with copies of either A or B: * One (1) of the following forms of valid photo-ID: * Driver license * Non-Driver Photo-ID Card * Passport * Employment ID * Two (2) of the following showing the applicant's name and address: * Utility or telephone bills * Letter from a government agency dated within the last six (6) months Employment ID (like school ID) can be issued by anyone since anyone in America can employ or teach others.

http://www.cnn.com/2005/LAW/07/05/crime.prevention.ap/index.html CHICAGO, Illinois (AP) -- Police installed video surveillance cameras around town and saw Chicago's murder rate fall to its lowest level in four decades. Now the cops hope to further cut crime by not only watching, but listening, too. The city is employing new technology that recognizes the sound of a gunshot within a two-block radius, pinpoints the source, turns a surveillance camera toward the shooter and places a 911 call. Welcome to crime-fighting in the 21st century. "Instead of just having eyes, you have the advantage of both eyes and ears," said Bryan Baker, chief executive of Safety Dynamics LLC, the company in suburban Oak Brook that makes the systems. The technology isn't just gaining favor in Chicago, where 30 of the devices have already been installed in high-crime neighborhoods alongside video surveillance cameras. Baker says dozens more installations will follow. In Los Angeles County, the sheriff's department plans to deploy 20 units in a pilot test, and officials in Tijuana, Mexico, recently bought 353 units, Baker said. Police in Philadelphia, Pennsylvania, and San Francisco, California, are close to launching test programs of their own, and New Orleans, Louisiana, and Atlanta, Georgia, also have made inquiries. Military use Safety Dynamics also works with the U.S. Army and Navy, developing systems that could detect a range of sounds such as glass shattering or diesel trucks slowing in an unexpected location. Some U.S. troops in Iraq already have a similar system that works differently. Designed quickly in late 2003 and early 2004 by the Defense Advanced Research Projects Agency and BBN Technologies Inc. of Cambridge, Massachusetts, a detector known as "Boomerang" can be mounted on the back of a moving vehicle to locate hostile gunfire. The Safety Dynamics system deployed in Chicago, known formally as Smart Sensor Enabled Neural Threat Recognition and Identification -- or SENTRI -- uses four microphones to triangulate, or zero in, on the shooter. By contrast, the Boomerang has sensors mounted atop a pole that detect shock and sound waves from a muzzle blast. In Chicago, police hope the SENTRI system will add momentum to a technology-fueled crackdown on guns and gang violence. The city in 2004 reduced its homicide rate to its lowest level since 1965 and police seized 10,000 guns -- successes that were in large part credited to a network of "pods," or remote-controlled cameras that can rotate 360 degrees and feed video directly to squad-car laptops. The SENTRI systems are an addition to that network. "They have been extremely successful," said Monique Bond, spokeswoman for the Chicago Office of Emergency Management. "We've been able to see the benefits that cameras and advanced technology bring to the community." Privacy matters The American Civil Liberties Union in Illinois is concerned about privacy rights being violated by the city's prevalent camera system. Spokesman Ed Yohnka said officers need to be properly trained in monitoring the cameras and only record activity in public spaces, such as sidewalks and streets. As long as the cameras and SENTRI system are set up in public spaces, they do not violate the law, said Northwestern University Law School professor Robert W. Bennett. "You don't have much in the way of privacy issues when you're in a public area," Bennett said. And local officials say it's hard to argue with the results. "The crime rates in Chicago are the lowest in 40 years. The price of keeping the community safe far outweighs civil liberty issues," Bond said. Baker stresses that SENTRI is programmed to recognize only gunshots, not record conversations or "bug" private homes. "There's no mechanism for other sounds like human voices," he said. SENTRI is the brainchild of Safety Dynamics and Dr. Theodore Berger, director of the Center for Neural Engineering at the University of Southern California. Each SENTRI contains a library of acoustical patterns, or "sound signatures," which Berger developed over several years. They're used to differentiate gunshots from other noises, such as traffic and construction, by measuring the unique decibel level of a bullet being fired. That way, a gunshot activates the system but a car backfiring does not. Adding SENTRI to an existing surveillance camera is not cheap, however. The system costs between $4,000 and $10,000 per unit. In Chicago, money forfeited by criminals is used to pay for both it and the accompanying cameras. As a result, Police Superintendent Phil Cline told a recent U.S. Conference of Mayors meeting, "the drug dealers are actually paying to surveil themselves." Copyright 2005 The Associated Press.

Posion Pill for ED?
by Tyler Durden 05 Jul '05

05 Jul '05

Hey...can some clever Cypherpunk think of a nice poison pill for ED? Theoretically, something like that is possible, but my only ideas aren't so hot. For instance, and elderly couple could sow some form of radioactive substance into their grounds, in quantities that would take longer than their life expectancy to kill them. Of course, a cleanup might be possible, but that would theoretically wack out the cost structures. There might be other less drastic measures that can be taken, however, such as finding a way to boost up the property costs so that the developers lose interest or perhaps even creating a very hard-to-find "landlord" that is collecting vast sums (on paper) for the rent of the property. These are crummy ideas, so relax. But I suspect something is possible. -TD

Getting them there in the first place is probably illegal, but once they're established, no development which destroys their habitat is legal, generally speaking. 2. Similarly, and even simpler, turn strategic portions of your property into wetlands or vernal pools. Similar protections vs development apply. Peter Trei
