With the increasing use of electronics and electronic commerce in our day-to-day lives, the importance of fraud-proof identification and recognition systems for use in security applications has grown .The improved understanding of biological systems and the ability to model them using computer algorithms has led to utilization of biometrics in authentication systems. Voice, Iris, Face, Signature, Hand Geometry are the biometrics that have been studied and applied to various kinds of identification and authentication systems.
Biometrics is a means of using parts of the human body as a kind of permanent password.
