Biometrics

Biometrics is the measurement and statistical analysis of people's physical and behavioral characteristics. The technology is mainly used for identification and access control, or for identifying individuals that are under surveillance. The basic premise of biometric authentication is that everyone is unique and an individual can be identified by his or her intrinsic physical or behavioral traits. (The term "biometrics" is derived from the Greek words "bio" meaning life and "metric" meaning to measure.)

 

Authentication by biometric verification is becoming increasingly common in corporate and public security systems, consumer electronics, and point-of-sale applications. In addition to security, the driving force behind biometric verification has been convenience, as there are no passwords to remember or security tokens to carry. Measuring someone’s gait doesn’t even require a contact with the person.

Biometric devices, such as fingerprint readers, consist of:

    A reader or scanning device.
    Software that converts the scanned information into digital form and compares match points.
    A database that stores the biometric data for comparison.
