To respond to these demands new technologies are being developed. Biometrics is one option, which is growing in popularity. Biometrics are automated methods of recognizing a person based on specific traits. It is the technical analysis of biological data to verify a person s identity. The person can be analyzed based on physiological or behavioral characteristics.
T here are two phases in biometrics, the first being enrollment.
In enrollment, a sensor measures the characteristic. The raw data, which processes the information from the scanner, forms a template. This process is repeated several times to ensure accuracy. The next phase, verification, the characteristics are measured, data is obtained, and the scan is compared with the stored template. If the match falls within a certain statistical range of values, the match is valid.
