Biometrics is an automated method of re cognizing a person based on physiological or behavi oral characteristics. Biometric recognition technology r elies upon the physiological characteristic of an i ndividual, 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, r etina or iris, face, fingerprints etc. examples of behavioral biometrics are voice pattern, signature, keystroke sequences, gait etc. Biometric systems have evolved significan tly over the past years from single-sample verification matchers to a wide range of multi-sample fully automated person recognition systems. Biometric technologies are becoming the fo undation of an extensive array of highly secure ide ntification and personal verification solutions. As the level of se curity breaches and transaction frauds increases, t he need for highly secure identification and personal verification tec hnologies is becoming apparent.
