Gummi bears defeat fingerprint sensors

Japanese Guy http://www.w2knews.com/rd/rd.c...nt_Scanners&mid=7574819783299094 defeats the fingerprint detectors with a cool process - he'll be arrested I suppose if he comes to the US....

This was going to be a snarky comment about why ziffle is wrong, but then it occured to me that maybe I should copyright my fingerprints.

Back when we were playing with DotCom money, we looked at fingerprint sensors that also used the same sensors as in medical Pulse Oximetry. The fingerprint had to match, plus you had to have 02 and pulse levels withing your norm. ie: if your pulse was high because a gun was being held to your head, it would not work.

of course.. thats when the 'bad guy' shoots you.

Arnold (the terminator) merely removed the victims eye and held it up to the detector -- another foolproof idea down the tubes....

Imagine what accelerated cloning will do to security...

"We need a full body clone of Bob the janitor in 15 minutes... we have to get to the vault, located in the basement under the laundry room."

Hmm.. embedded microchips could be an option, but you could still tear someone's arm off..

what about sub-conscience information? Secret information that you don't even realize you know, yet it allows you to access secured data or facilities as long as certain environments are right (ie, a gun is not pointed at your head).

I don't remember the Terminator ever doing the eyeball routine, but I do remember Simon Phoenix doing it.

IMDB agrees.

Ahnold took out his own eye, but that was only because it was damaged.

You can still measure pulse rate from an eyeball.. or blink a light and see if the pupil changes size.. or.. or..

Really good biometric sensors are also offset by hidden passive sensors: weight on the floor, heat/thermal image of one or more bodies.. your gait walking down the hall.. and a really "friendly system" is completely passive until the door shuts in your face (and behind you) and locks you into a mantrap you did not realize you walked into.

A preview from a future post to my own site, just because I love you all so much: http://www.heise.de/ct/english/02/11/114/

The boys from German computer mag c't defeat every commercially available biometric scanner with exotic hardware like inkjet printers.

For iris scans, to beat out every contingency meuon mentions they take the dramatic step of cutting a hole in the pupil of the printed picture of the eye and having anyone look through it during the authentication.

That was a great article, and applied to the low and medium end of the spectrum of such equipment well. I do not know if the high end is any better in the core electronics or techniques, but they do usually require multiple simultaneous biometric matches, which makes it harder (but not impossible).
