biometrics
The biological identification of a person. Examples are iris and retinal patterns, hand geometry and voice. Increasingly built into laptop computers, fingerprint readers have become popular as a secure method for identification. Biometrics not only deals with static patterns, but action as well. The dynamics of actually writing a signature can be analyzed, not just the resulting pattern (see biometric signature). Biometrics may be used as a secondary mechanism for authentication (see two-factor authentication).
