A Comparative Study of Biometric Technologies with Reference to Human Interface

Abstract

Traditionally the use of biometric devices has improved our ability to provide authenticated access to physical installations. Biometrics is the use of a person " s unique physiological, behavioral, and morphological characteristic to provide positive personal identification. Biometric systems that are currently available today examine fingerprints, handprints, iris and retina patterns, and face. Systems that are close to biometrics but are not classified as such are behavioral systems such as voice, signature and keystroke systems. They test patterns of behavior not parts of the body. Over the next few years, the use of biometrics will continue to grow and become much more commonplace. Today the core technologies have evolved and the cost of the equipment is going down dramatically due to the integration and increasing processing power. Certain applications of biometric identification technology are now cost-effective, reliable and highly accurate. As a result, there is no technological or financial barrier for stepping from the pilot projects to widespread deployment. This paper is an attempt to highlights the biometric technologies in concern with human interface.
