Biometric based authentication, the science of using physical or behavioral characteristics for identity verification is becoming a security mainstay in much areas. This paper examines the major forms of known attacks against biometric systems and Biometric template database attacks. A literature study of the attack points in each of the biometric system and the various methods to combat the attacks at these points is conducted and analyzed in this paper. In spite of numerous advantages of biometrics-based personal authentication systems over traditional security systems based on token or knowledge, they are vulnerable to attacks that can decrease their security considerably.
