The study of methods to uniquely recognize and authenticate the identity of humans based upon one or more intrinsic physical or behavioral traits (fingerprints, retinal patterns and so forth). Biometric technology offers several advantages over traditional systems. Unlike passwords, biometric traits cannot be lost or forgotten, and are very difficult to copy, share or distribute. Biometric systems can be used in tandem with passwords or tokens, improving existing security systems rather than replacing them.
