Biometrics

In the world of AIDC Biometrics’ is typically involved in the identification of a person is who they claims to be. This is achieved by comparing captured biometric data with that which has already been captured (Biometric Template of that person). This can also be done in conjunction with the use of a smart card user name or ID Number.

A Biometric System can often work under two modes;

Biometric Verification

A one to one comparison of a captured biometric with a stored template to verify that the individual is who they claim to be

Biometric Identification

A one to many comparison of the captured biometric against a biometric database in attempt to identify a known or unknown individual.

The first time an individual uses a biometric system they have to enrol, during which time biometric information from the individual is stored.

In subsequent uses, biometric information is detected and compared with the information stored at the time that they enrolled into the system.

Typical types of Biometric systems used within the world of AIDC are, fingerprint recognition, face recognition, Palm print recognition and iris recognition, which has in the main replaced retina recognition.
