These days asian hausfrau wear dark full-face visors, think a cross between a welding-helmet and an accounting visor. A dark plastic shield down to the chin. This is because they value paleness. The implications for meatspace anonymity should be obvious, at least where burkhas are rarer. One would have to test for IR transparency of course.

It would be great if someone would. It seems to me that this is more a matter of normal deployment delays, than widespread fear of patents. With early deployments, it is far from clear whether those paying are paying for patent licenses, or paying for sofware and expertise. Over time, in any given software technology, the cost of software and expertise tends to fall, eventually to near zero. At that point, it then becomes apparent how seriously people take any patent claims. --digsig James A.

MIT Study on Tin-Foil Hats :-)

The page was actually published in February, but showed up at www.fark.com today. (Hmm. Looks like Slashdot just got it also, so it'll probably be a bit slow downloading. I've included the text here, but the pictures make it worthwhile.) http://people.csail.mit.edu/rahimi/helmet/ On the Effectiveness of Aluminium Foil Helmets: An Empirical Study Ali Rahimi1, Ben Recht 2, Jason Taylor 2, Noah Vawter 2 17 Feb 2005 1: Electrical Engineering and Computer Science department, MIT. 2: Media Laboratory, MIT. Abstract Among a fringe community of paranoids, aluminum helmets serve as the protective measure of choice against invasive radio signals. We investigate the efficacy of three aluminum helmet designs on a sample group of four individuals. Using a $250,000 network analyser, we find that although on average all helmets attenuate invasive radio frequencies in either directions (either emanating from an outside source, or emanating from the cranium of the subject), certain frequencies are in fact greatly amplified. These amplified frequencies coincide with radio bands reserved for government use according to the Federal Communication Commission (FCC). Statistical evidence suggests the use of helmets may in fact enhance the government's invasive abilities. We theorize that the government may in fact have started the helmet craze for this reason. Introduction It has long been suspected that the government has been using satellites to read and control the minds of certain citizens. The use of aluminum helmets has been a common guerrilla tactic against the government's invasive tactics [1]. Surprisingly, these helmets can in fact help the government spy on citizens by amplifying certain key frequency ranges reserved for government use. In addition, none of the three helmets we analyzed provided significant attenuation to most frequency bands. We describe our experimental setup, report our results, and conclude with a few design guidelines for constructing more effective helmets. Experimental Setup The three helmet types tested The ClassicalThe Fez The Centurion We evaluated the performance of three different helmet designs, commonly referred to as the Classical, the Fez, and the Centurion. These designs are portrayed in Figure 1. The helmets were made of Reynolds aluminium foil. As per best practices, all three designs were constructed with the double layering technique described elsewhere [2]. A radio-frequency test signal sweeping the ranges from 10 Khz to 3 Ghz was generated using an omnidirectional antenna attached to the Agilent 8714ET's signal generator. The experimental apparatus, including a data recording laptop, a $250,000 network analyser, and antennae. A network analyser (Agilent 8714ET) and a directional antenna measured and plotted the signals. See Figure 2. Because of the cost of the equipment (about $250,000), and the limited time for which we had access to these devices, the subjects and experimenters performed a few dry runs before the actual experiment (see Figure 3). Test subjects during a dry run. The receiver antenna was placed at various places on the cranium of 4 different subjects: the frontal, occipital and parietal lobes. Once with the helmet off and once with the helmet on. The network analyzer plotted the attenuation betwen the signals in these two settings at different frequencies, from 10Khz to 3 Ghz. Figure 4 shows a typical plot of the attenuation at different frequencies. A typical attenuation trace form the network analyser Results For all helmets, we noticed a 30 db amplification at 2.6 Ghz and a 20 db amplification at 1.2 Ghz, regardless of the position of the antenna on the cranium. In addition, all helmets exhibited a marked 20 db attenuation at around 1.5 Ghz, with no significant attenuation beyond 10 db anywhere else. Conclusion The helmets amplify frequency bands that coincide with those allocated to the US government between 1.2 Ghz and 1.4 Ghz. According to the FCC, These bands are supposedly reserved for ''radio location'' (ie, GPS), and other communications with satellites (see, for example, [3]). The 2.6 Ghz band coincides with mobile phone technology. Though not affiliated by government, these bands are at the hands of multinational corporations. It requires no stretch of the imagination to conclude that the current helmet craze is likely to have been propagated by the Government, possibly with the involvement of the FCC. We hope this report will encourage the paranoid community to develop improved helmet designs to avoid falling prey to these shortcomings. Acknowledgments The authors would like to thank Andy (Xu) Sun of the MIT Media Lab for helping with the equipment, Professor George Sergiadis for lending us the antennae, and Professor Neil Gershenfeld for allowing us the use of his lab equipment.

Schwarzenegger Hits Snag at Polling Place By Robert Salladay, Times Staff Writer SACRAMENTO -- Gov. Arnold Schwarzenegger showed up to his Brentwood neighborhood polling station today to cast his ballot in the special election and was told he had already voted. Elections officials said a Los Angeles County poll worker had entered Schwarzenegger's name into an electronic voting touch screen station in Pasadena on Oct. 25. The worker, who was not identified, was testing the voting machine in preparation for early voting that began the next day. Somehow, Schwarzenegger's name was then placed on a list of people who had already voted, said Conny B. McCormack, the Los Angeles County registrar. Schwarzenegger's aides were informed of the problem when they arrived this morning to survey the governor's polling station. The poll worker told the governor's staff he would have to use a "provisional" ballot that allows elections workers to verify if two votes were made by the same person. McCormack said the poll worker did the correct thing. http://www.latimes.com/news/local/la-110805arnold_lat,0,7268769.story?coll=…

The event will take place from 9am to 3pm. I encourage you to register, if you had not already, at http://ecitizen.mit.edu/realid.html and to participate in our pre-conference online discussion, at http://ecitizen.mit.edu/realid.html. The program had to be postponed from November 17th due to a last minute important meeting called by the Department of Homeland Security on regulations implementing the Real ID Act related to privacy. Understandably, key privacy advocates and relevant Homeland Security individuals must now attend this meeting in Washington, DC. For this reason, we have decided to postpone the event to December 5th. We apoligize for any inconvenience this may cause. ** Regulations Under Real ID -- Join the Discussion ** I invite anybody on this list who may have opinions you wish to share on the topic of Real ID regulatory issues to post those ideas to our online forum under the new topic "Homeland Security Regulations". This topic thread is for participants in this Online Forum on the Real ID Act to share ideas you may have on problems and prospects associated with potential regulations under this federal law. All comments posted to this thread will be presented, as part of our conference proceedings, and published as part of our in-person conference to happen on December 5, 2005. The conference proceedings will also be presented to the Department of Homeland Security, as a record of the remarks made by participants, for their considerations as they determine how to implement the Real ID Act. I encourage you to attend the in-person meeting on December 5th at MIT and to participate in the dialog at the Online Forum.
