After making a plastic mould of a real finger, he then used gelatine - the stuff that sweets are made of - to make a fake finger, which he managed to use to trick 80 per cent of fingerprint readers. The same technique was used to make copies of latent fingerprints that could also trick the readers. Some fingerprint readers measure the blood pumping through a finger or its temperature in an attempt to prevent this type of spoofing.

It would be interesting to know which of these have published positive and negative failure rates

Iris recognition has actually been around for more than 20 years - a key patent "Flom and Safir" expired in Feb 2006. This has opened to door to commercial competition. Companies like ours are opening up the market with low cost camera devices, and low cost business models for algorithm deployment on devices and on server farms, where large scale cross-matching must take place for ID applications like Cards and Border Control.
