Biometrics is the study of how someone's physical or behavioral traits can be identified through automated methods. Biometrics is especially relevant to technology that measures and analyzes physical and behavioral characteristics of individuals such as fingerprints, voice, and facial patterns. More advanced biometric technology even focuses on the retina and iris of the eye, hand measurements, signatures, and the way someone speaks. Today, biometric technology is being incorporated into many ID card programs as an added security feature.
Biotechnology has advanced to the point that any one of these characteristics can be used to document identity and offer an additional means of protection. Imagine the ease of coming home and unlocking the door simply by pressing a fingertip against a special lock, or using a specialized ID Card that has been equipped with biometric technology. ID Cards were one of the first users of biometrics, using such elements as fingerprints and stored, automatically recognizable information.
Biometric technology has made huge strides because of an increasing need for security on all levels. The US Government has been toying with the idea of a Biometric National ID Card, Biometric Passports, Biometric Licenses, and Biometric Visas for visitors. All personal information is compiled into one huge database that can more easily be shared with different sectors of the State and Federal governments. Such as system would make it easier to identify criminals, prevent the use of false ID cards, and lower identity theft.
