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.

"Stewardess? Could I get some extra ice?"
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.

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. :-)
