On the security of XOR-method in biometric authentication systems
Tanya Ignatenko, Fmj Frans Willems · TU/e Research Portal · 2006
A biometric authentication system can be partitioned into a layer that ex-tracts 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-technique, is not always secure.
