Advancement in the field of Information Technology also make Information Security an important part of it. In order to deal with security, Authentication plays a major role. This paper presents a review on the biometric authentication techniques and its future possibilities. In biometrics, a human being needs to be identified based on some physical characteristic parameters. A wide variety of systems require reliable personal recognition schemes to either confirm or determine the identity of an individual requesting their services. The purpose of such schemes is to ensure that the rendered services are accessed only by an authenticated user, and not someone else. By using biometrics it is possible to confirm or establish an individual’s identity. The position of biometrics in the current field of Security has been depicted in this work. Also outlined opinions about the usability of biometric authentication systems, comparison between different techniques and their advantages and disadvantages in this paper.
