The artificial fingers and prints were created with gelatine by Japanese researchers who used the digits to get trick biometric systems into thinking they were seeing the real thing. Not only was it possible to fool the security systems with casts of fingers, the researchers found they could make convincing fakes using fingerprints lifted from glass. Experts say the experiments cast serious doubt on any claims that this type of biometric system can be made fully secure. 'Impressive work' The work was...
