Call for Abstracts (Multimedia Data Security)
by Bill Johnston-Lawrence Berkeley Laboratory-ITG 17 Dec '03

17 Dec '03

A Call for Abstracts As part of SPIE's EI '97 Electronic Imaging: Science and Technology 8-14 February 1997 San Jose Convention Center San Jose, California USA (http://www.spie.org/web/meetings/calls/pw97/pw97call_ei.html) Multimedia Data Security The growth of the use of public networks as the platform for multimedia applications in the past year has made it important to devise mechanisms for ensuring proper use of intellectual property and increased the importance of employing security mechanisms for video and audio data. This conference will serve as a forum for the exchange of ideas in the areas of security systems and mechanisms especially in applications that handle large data volumes. Papers are solicited in all areas of security systems and algorithms including but not limited to: - security systems for imaging applications - security systems for real time video applications - performance studies and comparisons for securing image data - watermarking and detection of fraudulent copying of intellectual property - metering schemes for intellectual property usage - audio and video encryption mechanisms - key management and security protocols for broadcast applications - payment systems for online multimedia applications - content protection mechanisms for online multimedia distribution. Please submit abstracts to Bill Johnston (johnston(a)george.lbl.gov) by August 15, 1996.

In the spirit of looking for points to quibble about: * food is mostly exempt from sales taxes, in most states in the U.S. Expect a major protest if a loaf of bread incurs a sales tax--I don't expect it anytime soon. * booze has a high tax rate, in excise taxes which can account for as much as 40% of the final price, plus sales tax. If the tax rises much higher, expect increased black market sales. * electronic and computer goods are often untaxed because many order them via mail-order. There have been proposals to tax out-of-state purchases, but the logistics and legal issues are murky (who gets the tax? and why should Idaho, for example, get the tax revenue for an item ordered from Georgia?). Of course, I'm not an expert in answering Igor's original question about where the taxes will come from. I'm more interested in reducing them, not raising them. --Tim May Boycott "Big Brother Inside" software!

The State of Texas requires by law that tax be paid on out of state purchases. You legaly should send in a check with copies of the receipts each year to the State Comptrollers Office. Historicaly everyone ignores it. Jim Choate

Chicago Area Physical Meet--

17 Dec '03

I just realized that I didn't put a subject on the last post I made I didn't put a Subject on it. Any way, the post, and a correction: Correction: The web page is at http://www.encodex.com/cpunk. Here is the original e-mail: >From snow(a)smoke.suba.com Fri Jul 26 12:13:09 1996 Date: Fri, 26 Jul 1996 12:12:57 -0500 (CDT) From: snow <snow(a)smoke.suba.com> To: cypherpunks(a)toad.com cc: alex(a)suba.com, andrew_loewenstern(a)il.us.swissbank.com, cabeen(a)netcom.com, erehwon(a)c2.org, lzkoch(a)mcs.net, paulrice(a)midway.uchicago.edu, somebody(a)tempest.ashd.com, strix(a)rust.net Message-ID: <Pine.LNX.3.93.960726114143.1310A-100000(a)smoke.suba.com> MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Status: RO X-Status: As previously discussed, I am announcing a Greater Chicago Area CypherPunks Physical Meet. The date is Saturday, 3 August 1996 at or around 4 p.m. at Ye Olde Saint Andrews Pub, 5938 N. Broadway, Chicago Il. Instructions are at the end of this post. Things _I_ would like to discuss, of course, this is me, so it is very amenable to changer: 1) Setting up a Chicago Area Remailer, not simply running a single remailer on a single account, but trying to go one better. 2) Discuss the possibility of a public event to spread the word about cryptography/encryption. 3) Discuss the next meeting. The reasons for selecting St. Andrews Inn: 1) It is relatively empty. 2) It has Food (Supposedly real good shepard's pie, made from real shepards(I asked)), Drink (Cider, and they know what snakebite is), and Non-alcoholic beverages. 3) It is easy (relatively) to get to. To get to St. Andrews Inn: By Car: Take Lake Shore Drive North until the LSD ends. Go North on Sheridan (right turn off of LSD) to Thorndale (About 5900 North) Turn left on Thorndale (heading west) and drive to Broadway (About 4 or 5 blocks) Park. St. Andrews is on the North West Corner of the intersection, under the green awning. By El: Take the Red Line (Howard/Dan Ryan) to Thorndale Go west 1/2 block from the El, This is Broadway St. Andrews is on the North West Corner of the intersection, under the green awning. I will try to have a map up at http://www.encodex.com/cpunk later today. Petro, Christopher C. petro(a)suba.com <prefered for any non-list stuff> snow(a)smoke.suba.com

That is, they don't seem to be too useful for anything. After all, cash works well. (It's rarely stolen, in my experience, or at least this is not a major concern. Traveller's checks work well, and can be "cashed" into the local currency. ATM machines fill the same function these "VISA Travel Money" cards apparently do; at least when I was in Europe the last time this is what I used, and my French francs were as untraceable as could be. As I see it, yet another marketing solution looking for a problem. A real step would be a true privacy card, a card issued in a jurisdiction unfriendly to U.S. investigators and offering various transaction-blinding options. I have to wonder what pressures have been put on the major credit card companies... --Tim May Boycott "Big Brother Inside" software!

Re: RPK Public Key Cryptography

Tall men in dark suits made Stephen Cobb <stephen(a)iu.net> write: >My apologies to the list if this subject is old hat but someone just pointed >me to the RPK Public Key Cryptography site and I was wondering what people >thought of this particular technology. It's just Yet Another PKC. Look at the history of LUC for a similar example: An amazing new breakthrough in PKC is announced, after a couple of years of analysis by cryptographers it's found to be no better or worse than existing PKC's, but in any case noone uses it because the existing patent covers only the US and expires in a few years whereas the LUC ones cover much of the world and will be around for ages. RPK is a similar case (actually it's in a somewhat worse position, by the time it's been subjected to enough analysis for people to trust it, the RSA patent will have expired, making RPK unmarketable). Other comments on the system: - The inventor apparently has no plans to publish details on the system in a journal or present it at a conference for peer review. - Someone who used to work with him rates him as a fairly competent programmer. His crypto skills are unknown. Given what happened with LUC I predict more of the same for RPK. Peter.

I agree, and this is one reason I am opposed to State-sponsored canine and feline genocide. And historically the lack of canine eradication programs has been a major way to control the "homeless problem," so the State is making the homeless problem worse by removing natural pest control mechanisms. --Klaus
