Abstract

The system aims to bind many biometric cryptosystem using a linker and to increase the matching accuracy at low threshold values. We demonstrate a two stage biometric cryptosystem in which each system uses two different biometric templates. Shielding functions is used to encrypt the biometric template. A One-Time Seed (OTS) generated by the OTS generator is used to link the two biometric cryptosystem. Hash algorithm principle is applied to generate OTS. Finally, the performance of the system is analyzed in terms of False Acceptance Rate (FAR) and False Reject Rate (FRR) for the biometric cryptosystem whereas many classic and contemporary biometric cryptosystem work well at high threshold values, but sharply falls when the threshold values are lowered in the matching process.
