Biometrics refers to the automatic identification of a person based on his or her physiological or behavioural characteristics. It includes fingerprint, iris, facial and retinal (Ratha, 2001). Biometrics technologies are becoming the foundation of an extensive array of highly secure identification and personal verification solutions. Biometrics is the science and innovation of measuring biological data. In information technology, biometrics are more often refers to as advancements for measuring and breaking down human body qualities, for example, fingerprints, eye retinas and iris, voice prints, facial patterns, and hand measurements, particularly for validation purposes. Verification by biometric confirmation is turning out to be progressively basic in corporate and open security systems and point of sale (POS) applications. Biometric gadgets, for example, finger scanners, comprise of: A reader; software that transforms scanned images into digitalized form and checks for a match, a database that stores the biometric information for comparism. To avoid fraud, biometric information is normally encrypted when its accumulated.
