Biometric cryptosystem using function based on-line signature recognition

In this paper we present a novel on-line signature based biometric recognition system, where cryptographic techniques are employed to provide protection and cancelability to function based signature templates. The performances of the proposed protected on-line signature recognition system are evaluated on the public MCYT signature database, and compared with the performances achievable using unprotected approaches, as well as other signature template protection approaches. The reported results show that, when using the proposed cryptosystem, protected and renewable signature templates can be properly generated and used for recognition purposes.
