A Comparison Based Study on Biometrics for Human Recognition

A biometric system provides automatic recognition of an individual based on a unique feature or characteristic possessed by the individual. These biometric characteristic may physiological or behavioral. Unlike other identification methods such as id proof, tokens and password, the distinct aspect of biometric recognition comes into light from randomly distributed features in human being. In this paper, I describe the novel comparison based upon various aspects to make easy selection for biometric device deployment in specific environment. This paper proposes a comparison among all kind of biometric system available in the society. The existing computer security systems used at various places like banking, passport, credit cards, smart cards, PIN , access control and network security are using username and passwords for person identification. Biometric systems also introduce an aspect of user convenience; it means one can be authorized by representing himself or herself. In this paper, the main focus is on working principal of biometric technique, the various biometrics systems and their comparisons.
