Biometric security is mainly implemented in environments with critical physical security requirements or that are highly prone to identity theft. Biometric security-based systems or engines store human body characteristics that do not change over an individual’s lifetime. These include fingerprints, eye texture, voice, hand patterns and facial recognition. An individual’s body characteristics are pre-stored in a biometric security system or scanner, which may be accessed by authorized personnel. When an individual walk into a facility or tries to gain access to a system, the biometric scanner evaluates his/her physical characteristics, which are matched with stored records. If a match is located, the individual is granted access.
The standard lock that uses a brass key may be thought of as a simple form of an “access control system”. Over the years, access control systems have become more and more sophisticated. Today, the term “access control system” most often refers to a computer-based, electronic card access control system.
Facial recognition is a way of recognizing a human face through technology. A facial recognition system uses biometrics to map facial features from a photograph or video. It compares the information with a database of known faces to find a match.
