A REVIEW ON SCOPE OF BIOMETRICS AND ITS APPLICATION

Abstract

Biometrics is technology of identifying uniquely human subjects by means of measuring & analyzing one or more inherent behavioral or physical traits. These human body characteristics include fingerprints, voice patterns, eye retinas & irises, facial patterns & hand dimension. Biometric systems are used to authenticate identity by measuring physiological and/or behavioral characteristics. So, two main categories of biometrics are ‘physiological’ and/or ‘behavioral’. The physiological category includes physical human traits such as palm print, hand shape, eyes, veins, etc. The behavioral category includes movement of human, such as hand gesture, speaking style, signature etc. The measurement of these traits helps within authentication using biometric systems. In this paper the study has been made about existing biometric system along with their working and application in modern era.
