Abstract

A new test called rotation search is proposed for user identification and cryptographic key regeneration in systems employing a digital representation of the iris which is called the iris code. When applied to the BIOSECURE, CASIA and NIST-ICE data bases the rotation search shows, on average, a two fold reduction in false rejection ratio (FRR) with a false acceptance ratio (FAR) equal to zero, in comparison with the standard search employed in other systems. The highest improvement reached in FRR by the rotation search against the standard search is about 100 times for a single iris and 85 times for the two irises of a user, and in many cases the measured FRR is equal to zero.
