Fingerprints

An example of a physiological biometric factor, which is unique to a subject. It uses near-infrared light to measure vein patterns in the palm, which are as unique as fingerprints. Some palm scans identify the layout of ridges, creases, and grooves on a person’s palm to establish identity or provide authentication. See palm topography.

An example of a biometric factor, which is a behavioral or physiological characteristic that is unique to a subject. The layout of ridges, creases, and grooves on a person’s palm is used to establish identity or provide authentication. This is the same as a palm scan and similar to a fingerprint.

Characteristics of any person that can be used to identify or authenticate the person. Physiological biometric methods include fingerprints, face scans, retina scans, iris scans, palm scans, hand geometry, and voice patterns. Behavioral biometric methods include signature dynamics and keystroke patterns.

A comparison metric for different biometric devices and technologies; the error rate at which FAR equals FRR. The lower the CER, the more accurate and reliable the biometric device. The point at which the false acceptance rate (FAR) equals the false rejection rate (FRR). This is the point from which performance is measured in order to compare the capabilities of different biometric devices.

The initial process of collecting biometric data from a user and then storing it in a template for later comparison. The process of establishing a new user identity or authentication factor on a system. Secure enrollment requires physical proof of a person’s identity or authentication factor. Generally, if the enrollment process takes longer than two minutes, the identification or authorization mechanism (typically a biometric device) is not approved.
