Abstract :
This paper describes a secure fingerprint verification system based on the fuzzy vault scheme, where the sensitive biometric template is not stored, but a transformed version. We propose an adaptive alignment technique to reach the most reliable reference point, and a methodology to construct a set of rotation and shifting invariant features, acting as the lock set for the fuzzy vault. We investigate the parameters of the fuzzy vault and the number of the templates needed to obtain a reliable reference point, such that a high unlock complexity for attackers with an acceptable unlock rate for the legal users is achieved.
