Trends in Biometric Techonology

Abstract

Biometrics is playing a major role in automating personal identification system deployed to enhance security in several applications including use of passports, cellular telephones, automatic teller machines computer systems and driver licenses. The use of biometric features for identification purposes requires that a particular biometric factor be unique for each individual, that it can be readily measured, and that it is invariant over time. When used for personal identification, biometric technologies measure and analyze human physiological and behavioural characteristics. A person’s physiological characteristics are based on direct measurement of a part of the body such as, fingerprint, hand geometry, facial geometry, and eye retinas and irises. Behavioural characteristics are based on data derived from actions, such as speech and signature. The aim of this paper is to provide an overview of the field of biometrics including the current trends. The commonly-used biometrics have been evaluated and some future research directions have been identified.
