Blind Signature Patent Expiration Party this Saturday
by Lucky Green 14 Jul '05

14 Jul '05

Friends, colleagues, and co-conspirators, It has been 17 long years and now the time is finally here to celebrate at the: BLIND SIGNATURE PATENT EXPIRATION PARTY ======================================= WHAT: A party to celebrate the expiration of the Blind Signature patent. WHY: U.S. Patent 4,759,063 ("Blind Signature Systems") to David Chaum is the core invention enabling privacy-protecting electronic payment systems and credentials. It was a truly ingenious, ground-breaking contribution. Unfortunately the existence of the corresponding patent, which was notoriously difficult to license, prevented this great invention from receiving the wide use that it so very much deserved. For a copy of the patent, see http://www.pat2pdf.org/pat2pdf/foo.pl?number=4759063 Unlike copyrights these days, patents do expire. The blind signature patent will expire on July 19, 2005, next Tuesday. Since weekends tend to fit better with the schedules of potential party goers than weekdays, we are holding the party this Saturday instead. The 17 years that this patent has been in effect has been an awfully long time for the many of us that hoped to make use of this technology to help citizens to maintain privacy in the age of the Internet and the patent's expiration is a much overdue reason for celebration. WHO: If you know what blind signatures are you are invited. WHEN: This Saturday, July 16, starting at 1:00 PM PDT WHERE: Since the number of inquiries I received in response to the party pre-announcement exceed the maximum occupancy limit of my home and since the weather promises to be excellent, we will hold the party in a beer garden instead. Drinks are on me! We will meet at the Alpine Inn (aka Alpine Beer Garden) 3915 Alpine Road, Portola Valley, CA 94028 USA AWARDS: Those that can demonstrate that they have created a full system that makes significant use of the blind signature patent by 4 PM on Saturday will be invited to and receive a free dinner at the afterparty. So get coding! (Pr0duct Cypher, where are you)? A team of judges will determine if a particular system qualifies for the award. AFTERPARTY: A handful of us plan to have dinner at a swanky restaurant on patent-free Tuesday. Email me or talk with me at the party if you are interested in joining. Space is limited. You will have to pay for your own food at the Tuesday dinner unless you qualify for the award above or your name is on the blind signature patent. Looking forward to see you all this Saturday, --Lucky ________________________________________________________________ This email could have been PGP encrypted.

Drug-traffickers' Trunk-mounted Evidence-ditching Rocket Fails to Take Off
by Bill Stewart 13 Jul '05

13 Jul '05

My brother's summary, spoken by a Wile E. Coyote cartoon figure: "2 KY meth traffickers rigged up their car so if cops closed in a small rocket with their stash would launch itself from the trunk" ..... "that never works" "meep meep" Fox News Story: http://www.foxnews.com/printer_friendly_story/0,3566,161609,00.html Drug Rocket Fails to Take Off Tuesday, July 05, 2005 Drug dealing really may be rocket science. Two accused methamphetamine traffickers apparently rigged up their car so that if cops closed in, a small rocket carrying their stash would pop up from the trunk and launch itself far from the long arm of the law. For some reason, the rocket never achieved liftoff when Missouri State Highway Patrol (search) officers pulled over Michael Ray Sullivan, 41, and Joseph C. Seidl, 39, both of Kentucky, on June 24 in Kingdom City. The $13,534 in cash in the 1990 Ford Thunderbird was interesting enough, Kansas City U.S. Attorney's Office spokesman Don Ledford told the Columbia (Mo.) Daily Tribune. Far more intriguing was what was in the trunk: three dud pipe bombs and a "hobby-style" rocket, three to four feet long, all packed with meth worth up to $145,000. Ledford explained that a web of ropes and pulleys lifted the rocket into launch position when the trunk lid was opened. The rocket could then be ignited from inside the car using the dashboard cigarette lighter. Cops are pretty certain the rocket was meant to be an escape pod for the drugs, but Ledford diplomatically declined to speculate. "But they did have the meth inside the rocket," he admitted, "and it could be launched from inside the car." - Thanks to Out There reader Jen J.

Paintball "Terrorist" Sentenced
by Eric Cordian 13 Jul '05

13 Jul '05

I'd just like to say that the American troops who carried out Bush's illegal war in Iraq, which killled 100,000 Iraqi civilians, are war criminals, and I'd like to encourage all of AmeriKKKa's victims to capture them and bake them in pies, after forcing them to bark like dogs and poop themselves. Now, is that worth life in prison? Only in a police state. In a real democracy whose citizens are free, it's protected political speech. Too bad AmeriKKKa isn't one of those. Fuck Bush. This, by the way, in case you can't read through the inflammatory bullshit in the wireservice story, was the case of some individuals who were deemed to have engaged in a conspiracy to wage war against the US, because in addition to being Islamic, and denouncing Bush's war, they played paintball. http://www.newsday.com/news/nationworld/nation/wire/sns-ap-terror-paintball… ----- ALEXANDRIA, Va. -- A prominent U.S.-based Islamic scholar who exhorted his followers after the Sept. 11 attacks to join the Taliban and fight U.S. troops was sentenced Wednesday to life in prison. Ali al-Timimi of Fairfax was convicted in April of soliciting others to levy war against the United States, inducing others to aid the Taliban, and inducing others to use firearms in violation of federal law. The cleric addressed the court for 10 minutes before his sentencing. "I will not admit guilt nor seek the court's mercy. I do this simply because I am innocent," al-Timimi said. The cleric addressed the court for 10 minutes before his sentencing. "I will not admit guilt nor seek the court's mercy. I do this simply because I am innocent," al-Timimi said. Prosecutors said the defendant, a native U.S. citizen who has an international following in some Muslim circles, wielded enormous influence among a group of young Muslim men in northern Virginia who played paintball games in 2000 and 2001. Authorities said they were a "Virginia jihad network" training for holy war around the globe. ... -- Eric Michael Cordian 0+ O:.T:.O:.

Attack on Brands blind signature
by cypherpunk 13 Jul '05

13 Jul '05

eprint.iacr.org/2005/186 is an attack by Xuesheng Zhong on several blind signature schemes, including one widely discussed on the Cypherpunks mailing list back in the 1990s by Stefan Brands. The paper seems to show that it is possible for the bank/mint to recognize blind signatures (i.e. untraceable electronic cash tokens) when they are re-submitted for deposit, which is exactly what the blind signature is supposed to prevent. The math looks right although I haven't tried to look back at Brands' old work to see if it is correctly described in the new paper. CP
