An iris-based Interval-Mapping scheme for Biometric Key generation
Christian Rathgeb, Andreas Uhl · 2009
In order to increase security in common key management systems, the majority of so-called Biometric Cryptosystems aim at coupling cryptographic systems with biometric recognition systems. As a result these systems produce cryptographic keys, dependent on biometric information, denoted Biometric Keys. In this work a generic approach to producing cryptographic keys out of biometric data is presented, by applying so-called Interval-Mapping techniques. The proposed scheme is adapted to iris, which has not yet been examined according to this technique, as well as on-line signatures to demonstrate that this approach is generic. Performance results show that the approach pays off.
