Biometric Fingerprint Security Readers

Biometrics consist of automated methods of recognizing a person based on unique physical characteristic. Each type of biometric system, while different in application, contains at least one similarity: the biometric ID must be based upon a distinguishable human attribute such as a person’s fingerprint, iris, voice pattern or even facial pattern.

Today Biometric fingerprint readers are by far the most popular form of biometric access security used, with a variety of access control systems on the market intended for general and mass market usage. Long gone are the huge bulky Biometric fingerprint scanners, now a Biometric fingerprint reader can be small enough to be incorporated into a laptop for security.

A fingerprint is made of a series of ridges and grooves. Once a Biometric fingerprint is captured the system locates the minutia points. These minutia points occur where the lines of the ridges begin, end, branch off and merge with other ridge lines. These points are then mapped and a line is drawn between each point. This creates a map of how each point relates to the other points. The map is then stored as a data stream called a minutia template in a database for future comparison with other presented fingerprints. It is important to note that during the entire process no fingerprint images are stored on the system and a fingerprint image cannot be recreated from the minutia template.
