Biometrics is the study of the measurable physical or biological characteristics that are unique to each person. In information technology, biometrics usually refers to technologies for measuring and analyzing human body characteristics such as fingerprints, eye retinas and irises, voice patterns, facial patterns, and hand measurements, especially for authentication purposes.
Fingerprints provide one of the oldest and most accepted forms of personal verification because no two fingerprints ever have been found to be the same. The use of fingerprints is accurate, reliable, convenient, and unobtrusive. However, a severely cut or damaged finger can render a reading invalid.
