Jello Threat

Posted by Eric at 2:14 pm. Filed under: General

This is way old (like three years), but I had to post this story from May of 2002, since I was on the identity theft kick this morning.

Tsutomu Matsumoto, who teaches mathematics and cryptography at Japan’s Yokohama National University, has demonstrated that if one makes a mold from a human finger (which can be done easily with dime store modeling compounds or with molding materials used by dentists to make impressions for dentures) and fills it with the same material used to make “Gummi Bears” and “Gummi Worms,” he can cast a phony fingertip that’s good enough to trigger virtually all of the most sophisticated biometric devices. (”Gummies” are elastic confections that usually take the form of bears and worms in the US, and of lozenge-shaped candies — often with uncannily accurate fruit flavors — in Japan. They’re commonly made either from gelatin or from carageenan, a soluble fiber derived from kelp.)

Matsumoto has also demonstrated that one can capture a third party’s fingerprint (perhaps from a drinking glass or other hard surface), make a series of molds by etching a standard epoxy-glass printed circuit board (the thickness of the copper is a good match for the depth of a typical fingerprint), and stamp out dozens of replicas of the victim’s finger.
