Abstract

Biometrics deals with the automatic recognition of individuals based on statistical analysis of physiological and/or behavioral characteristics. Any human physiological or behavioral characteristic that is unique, universal, stable, and collectable could be used as a biometric characteristic.

In the modern automated world, access to a reliable authentication system becomes increasingly essential. However, traditional authentication methods based on the user's exclusive knowledge, such as password, personal identification number (PIN), or something belonging to one, such as a cardkey, smart card, or token [like identity cards (ID)], can hardly meet the requirements of the reliability of an authentication system because passwords or PIN may be forgotten and ID cards can be lost, forged, or misplaced. Compared with traditional methods, biometrics can provide enhanced security and convenience. As biometric recognition systems are increasingly deployed for many security applications, biometrics and its applications have attracted considerable interests. Recently, biometrics has emerged as one of the most reliable technologies for future human identification and verification.
