ABSTRACT
For thousands of years, people have sought to restrict others from having access to certain locations, objects, and information they either own or hold. The traditional means of gaining access to these restricted articles have been the presentation of a password or a key. Little has changed over the years, and although modern passwords may be encrypted or the keys may have become more complicated, the same basic techniques of access are used (Rejman-Greene 2002). Recent advances in computer software and technologies have allowed a new method of identity confirmation and verification to be explored — that of biometric identifiers. Thus, we have moved away from using as a key something that we have acquired to an inborn characteristic of our bodies (Furnell and Clarke 2005).
