Most American airports, especially those with international connections, routinely videotape all passengers. I can't cite a source for this, but I think it's common knowledge (not that this means its true).
There was an article in a recent New Scientist (maybe last week) that mentioned the use of infrared scans of faces to identify people since its very hard to change the thermal image of your face by surgery. The plan is to scan every one passing through the airport and forward the image to the FBI (or whoever the local cops are I guess, but it said FBI) and they check out thier database of know terorists (and cypherpunks) and it rings the local gaurds if they get a match. I can try to find the whole article if anyones interested.

IR scans can be *so* easily messed up that I'm amazed anyone is seriously suggesting this. A facial scan can be messed up by downing a cold drink. Downing a hot drink. Ambient temperature. Sweating. Sucking an ice cube, though, is one of the easiest. Or just running it across your forehead and cheeks. Even a hat can mess one up as far as recognition purposes go. ---Ken McGlothlen mcglk@cpac.washington.edu mcglk@cpac.bitnet mcglk@c3po.ring.wizards.com (NeXTmail)
RE: IR Face scans... Time to get our hands on some cans of compressed-air dust cleaners... when you hold them upside down and spray, they spray a super-cold liquid which quily evaporates. BTW: you can also just pop a 400mg Niacin capsule... Niacin will quickly dialate all your capilaries bringing lots of blood to your face and making you look like a lobster. That should mess up any scan... so if you're a wanted crook in an airport that uses ir-face biometrics, just pop niacins like them were pop-corn. :-)
