ABSTRACT

Biometric Authentication Systems plays a vital role in data security. It is widely adopted and accepted technology everywhere to authenticate unique personal identification based on his or her physiological or behavioral traits. Physiological biometrics involves the face, finger-prints, hand geometry, palm-prints, iris, retina patterns, ear, and DNA, while behavioral biometrics includes the signature, voice/speech, keystroke, and gait/walking style. By using biometric authentication system a person could be identified based on "who he/she is" rather than "what he/she has" (id card, token, key) or "what he/she knows" (password or PIN). The various applications of biometric authentication system are now cost-effective, reliable and highly accurate and the need to be addressed form making biometric systems an effective tool for providing information security. This paper have been discussed the various biometrics authentication system, characteristics, challenges and their applications in concern with the human interface.
