What is a biometric system?
A biometric system is a technological system that uses information about a person (or other biological organism) to identify that person. Biometric systems rely on specific data about unique biological characteristics in order to work effectively. A biometric system involves the running of data through algorithms for a particular result, usually relating to positive identification of a user or other person.

The peculiarity of today's biometric systems is with a specific use of the term 'biometrics' connected. Biometrics, in general, is a use of biological data in technology. Biometric systems that focus solely on identifying people have become the most important type of biometric system in today's IT world.

Governments, businesses, and organizations can use biometric systems to get more information about individuals or about a population as a whole. Many biometric systems are developed for security applications. An airport scanning device, 'bio-password' system, or internal data collection protocol is an example of a biometric system that uses identifying data for a security outcome.
