Biometrics

“Biometrics” is a general term used alternatively to describe a characteristic or a process. As a characteristic:
1. A measurable biological (anatomical and physiological) and behavioral characteristic that can be used for automated recognition.
As a process:
2. Automated methods of recognizing an individual based on measurable biological (anatomical and physiological) and behavioral characteristics. Biometric systems have been researched and tested for a few decades, but have only recently entered into the public consciousness because of high profile applications, usage in entertainment media (though often not realistically) and increased usage by the public in day-to-day activities.

A typical biometric system is comprised of five integrated components: A sensor is used to collect the data and convert the information to a digital format. Signal processing algorithms perform quality control activities and develop the biometric template. A data storage component keeps information that new biometric templates will be compared to. A matching algorithm compares the new biometric template to one or more templates kept in data storage. Finally, a decision process (either automated or human-assisted) uses the results from the matching component to make a system-level decision.
