In todayâ??s world automation is encompassing virtually every walk of life and human control functions are delegated to technical equipment. No doubt this results in emerging requirement of highly reliable personal identification system for authenticated access of resources and to reject imposters. Traditional password based verification systems can be easily hacked when a password is divulged to an unauthorized user. A number of biometric techniques have been proposed for personal identification by various researchers. Biometric includes something which one does not need to remember or carry a token. Biometric based personal authentication systems use physiological or behavioral traits of a person for recognition purpose. Physiological traits include fingerprint, face, hand geometry etc. and behavioral traits are speech, handwriting, key strokes etc. During past few years, there has been remarkable growth in biometric recognition technology due to the increasing requirement of highly reliable personal identification and authentication in a number of government and commercial applications. In this paper we present a comparative study of various biometric recognition techniques suggested for authentication purpose and to reject imposters.
