Definition: biometrics


The biological identification of a person. Examples are face, iris and retinal patterns, hand geometry and voice. Built into laptop computers and smartphones, fingerprint readers have become popular as a secure method for identification.

Active vs. Passive Biometrics
Active biometrics requires users to perform some activity such as running their finger across a reader or looking into the camera. Passive biometrics senses gestures and rhythms. For example, lifting a smartphone may turn it on, and every person has a unique typing pattern (see biometric signature and keyboard biometrics).

More Security
More secure than passwords or even smart cards, which can be stolen. biometrics may be the primary or secondary authentication mechanism (see two-factor authentication). However, biometrics can be circumvented; for example, fingerprints captured from a water glass can fool scanners. See authentication, fingerprint reader, wearables, smart clothes, facial recognition, voice recognition and iris recognition.




A Biometric Mouse
SecuGen's EyeD Mouse includes a fingerprint reader on the thumb side of the device. It takes less than a second for the EyeD Mouse to verify a fingerprint. (Image courtesy of SecuGen Corporation, www.secugen.com)
