Executive Summary

Biometrics is an automated method of recognizing a person based on physiological or behavioral characteristics. Biometric recognition technology relies upon the physiological characteristic of an individual, offering positive identification that is difficult to counterfeit. Examples of physiological biometric features include height, weight, body odor, the shape of the hands, vein patterns, retina or iris, face, fingerprints, etc. examples of behavioral biometrics are voice pattern, signature, keystroke sequences, gait, etc. Biometric systems have evolved significantly over the past years from single-sample verification matchers to a wide range of multi-sample fully automated person recognition systems.
