A Review on Different Multi Biometric Cryptosystems

Abstract: Biometric Identification is one of the area related to person recognition by means of physiological and behavioral features like iris, fingerprints, voice, face, etc. Biometric cryptosystems can be used to protect the biometric template. It provides a better solution for the cryptographic key generation, encryption and decryption. Single Biometric cryptosystems use a single biometric feature to protect the data, while multi biometric cryptosystems uses two or biometric features. Multi biometric cryptosystem uses different fusion techniques. In this paper, a survey of different kinds of multi biometric cryptosystem is done.

Keywords: biometric; fusion; cryptosystem.
