[A discussion from cypherpunks.

With the use of mirrors, Hizbullah is working to block the effectiveness of the surveillance cameras installed along the northern border. The cameras, mounted atop armored personnel carriers, were deployed following the unilateral IDF withdrawal from southern Lebanon in June. Hizbullah activists are using mirrors to blind the cameras with sunlight, making surveillance increasingly difficult at a time when the northern border remains on high alert. ********** Date: Sat, 11 Nov 2000 04:56:18 -0500 Message-Id: <3.0.5.32.20001111015525.00ad46f0 () idiom com> Originator: cypherpunks () openpgp net From: Bill Stewart <bill.stewart () pobox com> To: Multiple recipients of list <cypherpunks () openpgp net> Subject: Re: low tech surveillance-cam countermeasures in Israel At 01:37 PM 11/10/00 -0500, anonymous () openpgp net wrote:

Lasers can be good too.

APCs do make it harder to use the traditional Anglo-American approaches techniques developed for speed-trap cameras, which involve ski masks and spray paint or baseball bats. But rifles can be fun. On the other hand, cameras keep getting cheap, and you can hide radio-equipped web-quality cameras for nearly no money anywhere you've got electricity, so getting all (or enough) of them can be harder.

OTOOH, if you've a little money to invest, the optical reflection DSP techniques developed to detect sniper rifle scopes could be used to find cameras in large areas. (Laser reflected off spinning scanning mirror into target area, digitize reflected light and process to detect internal reflections of lens assemblies. Done right it can identify scope by make and model, mirror gives relative bearing to points of interest.) This technique should apply to everything but pinhole lenses, which aren't very useful for staring-eye type field surveillance. A simple commercial version of this is already available to sweep for hidden cameras in a small room type environment, scaling for large field use should be relatively simple with better optics and detectors. Its likely a few of the spooks on this list have used such equipment, its probably been deployed for a number of years now by the US. ------------------------------------------------------------------------- POLITECH -- the moderated mailing list of politics and technology You may redistribute this message freely if it remains intact.
