A biometric authentication system operates by acquiring raw biometric data from a subject e.g., fingerprint and iris images. This paper summarizes the various aspects of biometric system security. It broadly categorizes the various factors that cause biometric system failure and identify the effects of such failures. In this paper, biometric templates are stored in central database. Preserving the privacy of this digital biometric template has become very important. This paper is on biometric template security.
