Biometrics: Security Issues and Countermeasures

One of the fundamental aspects for the protection of information systems is authentication. Authentication involves confirming the identity of a person or any entity that could be a hardware or software program. One way of authentication is biometric technology. Biometric recognition offers a reliable solution to the problem of user authentication. Biometric systems are widely deployed in various applications, so there is a lot of concern regarding to their privacy any security technology. Biometric technology will publicly be accepted when these systems have low error rates, temper proof and are robust. In this paper, we have analyzed various possible attacks associated to biometric technology. Later we have specified the details of dealing with these kinds of attacks, e. g. spoofing attacks. Moreover, biometric liveness approaches are discussed to deal with security threats.
