Wanna new fingerprints ?

Tsutomu Matsumoto is a Japanese mathematician, a cryptographer who works on security, and he decided to see if he could fool the machines which identify you by your fingerprint. This home science project costs about £20. Take a finger and make a cast with the moulding plastic sold in hobby shops. Then pour some liquid gelatin (ordinary food gelatin) into that mould and let it harden. Stick this over your finger pad: it fools fingerprint detectors about 80% of the time. The joy is, once you’ve fooled the machine, your fake fingerprint is made of the same stuff as fruit pastilles, so you can simply eat the evidence.
