Biometrics Security System
A biometrics system captures a sample of the biometrics characteristic (biometrics sample). Unique features are then extracted by the system and converted into a mathematical code (biometrics data). The biometrics data is then stored as the biometrics template (also known as template or reference template) for that person. When an identity needs checking, the person interacts with the biometrics system for a second time. A new biometrics sample is taken. This is compared to the template. If the template and the new sample match, the person's identity is confirmed.
