Biometrics is a rapidly developing in sensor technology. From security point of view, it is better than traditional technology. Biometrics authentication system overcomes the drawbacks of traditional technology like passwords and token based schemes, because biometrics system establishing automatic personal recognition based on behavioral and characteristics of an individual like (face, iris, fingerprints, palm print, hand geometry, voice recognition). So biometrics system raises the security, privacy, trust issues and accuracy. Templates security is the main issue of biometrics system because it is the critical points of biometrics systems.
