This paper discusses the various security threats to the biometric template based Unique Identification systems which are used for user identification and authentication. The biometric systems which use various physical and behavioral characteristics of the users for identity verification are prone to various security attacks that decreases their security considerably. In this paper I have presented a discussion on the threats to physical biometric traits (fingerprint, iris and face recognition) based systems. The paper discusses these possible attacks that may hamper the normal functioning of the biometric authentication system.
