Passwords and personal identification numbers (PIN) are information that we need to remember since the day we started interacting with digital systems. Do we know the count of passwords we need to remember? Do we know if we forgot a password already? Some of these passwords also known as passphrase are long to remember that we need to come up with a pattern to create such passwords. We sometimes rely on tools such as a sticky, PDA or text file to store these lists of passwords.

Would it be easy to identify yourself as if you are been seen by another individual acknowledging their acquaintance with you? That’s exactly what a biometric authentication technology does. It uses a physical or psychological trait that the individual always has with him or her for identification and/or authentication.

In this system, the physical or psychological trait of an individual is measured, recorded and quantified to obtain a biometric enrollment. The system can be sure to a degree of certainty that a person is who he/she claims to be based on this initial enrollment. A template, which is a long string of alphanumeric characters that describes the characteristics or features of the person, is created at each enrollment based on a biometric algorithm. The algorithm that translates physical traits to a digital representation is called the biometric algorithm. The algorithm also allows matching of a newly created template (live template) with that of the initially created one. If the matching is not closed enough, the person will not be verified.
