Abstract

A biometric authentication system can be partitioned into a layer that extracts common randomness out of a pair of related biometric sequences [Maurer, 1993] and a layer that masks a key sequence with this common randomness. We will analyze the performance of such a layered system first, and will show that an alternative method, the XOR- echnique, is not always secure.
