Fingerprint Scanners Fooled By Play-Doh

From the article: "Schuckers' biometric research is funded by the National Science Foundation (NSF), the Office of Homeland Security and the Department of Defense. She is currently assessing spoofing vulnerability in fingerprint scanners and designing methods to correct for these as part of a $3.1 million interdisciplinary research project funded through the NSF."

      Yes, that's what I was trying to get to in my last sentence, i.e. that that won't work either. As the guard will have a tendency to become complacent given that the e.g. fingerprint scanner is "foolproof" and not even bother to look at it as the person scans his finger. Compare if you will the absymal successrates of photo id:s when put to the test. The guard there is actually required to look at it as a part of the procedure (i.e. it's not incidental to the procedure as it is here), but anything usually goes. Even cartoon pictures (I know of one instance of Donald Duck) have gotten people into military bases. If I was a betting man, I'd bet that just holding the severed finger between the thumb and forefinger on the hand (in effect presenting a six fingered hand) would let you in more often than not, even with a fairly "vigilant" guard.

Adding one of these though would really drive up costs. Here is a pic of the unit I am talking about. $675, ouch.

    The non-invasive principle of operation of these is pretty neat, and might interest slashdoters. They work by shooting dual wavelengths of light through the finger, namely infra-red and a visible red color. On the other side of the finger, a sensor relays readings to a signal processor, which distinguishes between flesh, bone, and what-not based on the absorption differential between the two wavelengths, so it can isolate out variables between different kinds of fingers. The result is incredibly precise, and the LED on the front flashes in precise sync with one's pulse.
