Biometric Authentication and Template Protection

Biometric template offers a dependable approach to the trouble of user authentication in identity management structures. Various biometric technologies were developed and effectively deployed around the arena which includes fingerprints, face, iris, palm-print, hand geometry and signature. Fingerprints are the most popular due to their ease of capture, forte and patience through the years, as well as the low cost of sensors and algorithms. A biometric authentication scheme with template protection this is irreversible in opposition to almost all types of adversaries. If a biometric template inside the database of the device of someone is compromised that consequently might imply identification robbery of that man or woman. Most biometric systems which are presently in use, generally use a single biometric trait i.e. fingerprints because of its uniqueness and persistence, such system to set up identity, they're called uni-modal biometric structures that have a few obstacles .This paper proposes of genuine encryption technique for template security. A template protection scheme with provable safety and acceptable reputation overall performance has to date remained elusive.
