What is Biometrics?
Biometrics is a method of identifying individuals based upon one or more intrinsic physical or behavioral traits.
When used in computer science, it has different dimensions. For one, it is a form of identity access management and secondly it is a form of access control. This means that it will identify individuals, and give or deny permission to access devices, or areas.
Two characteristics make it applicable for security. There is the physiological element, which relates to the shape of the body. For example, physiological biometrics include fingerprints, facial recognition, DNA analysis, palm print, hand geometry, and iris recognition.
The second kind is behavioral biometrics related to the behavior of a person. For example, typing rhythm, gait, voice, and handwriting. Another term used by some researchers is behaviometrics.
