Biometrics: Fingerprint Matching

Before an individual can be verified via his or her fingerprints, it is necessary to capture fingerprint samples using a process that is often referred to as enrolment. A chip called a sensor is used to capture the entire fingerprint image.

Information from the image is stored by creating what is called a template. The template is not actually the image, but can be thought of as an "information extract" of the fingerprint image. To create the template, the fingerprint image is processed by a special algorithm and the resulting data is entered into a database. The algorithm creates a digital representation of the fingerprint image.

Each subsequent attempt to access the system requires the fingerprint of the user to be captured again and processed into a digital template. That template is then compared to those existing on the database to determine if there is a match. If a match is made, the user is granted access.
