Gummi Bears Can Also Fool Fingerprint Scanners

About 6 months ago we ran a piece on how a finger made out of Play Doh could foil many retail fingerprint scanners. Not to be outdone, a Japanese cryptographer named Tsutomu Matsumoto has found that Gummi Bears make an even better fake fingerprint, and are the cornerstone of a do it yourself fake fingerprint lab that require bears, a digital camera, and a PC. According to Mastsumoto, the gelatin used to make Gummi bears can be poured into a mold to make a finger, and this fake finger was able to fool scanners 4 out of five times.
Not to be outdone, using the fumes from superglue, Matsumoto was able to highlight a print from a drinking glass and photograph it with a digital camera, and then imprint the high res print on the gummi bear finger using a photo sensitive printed circuit board he picked up in a hobby shop. And it worked - so well that cryptography experts are recommending that these systems go right back to the drawing board.
