The term "Biometrics" is derived from the Greek words "Bio" (life) and "Metrics" (to measure). Automated biometric systems have only become available over the last few decades, due to significant advances in the field of computer processing. Many of these new automated techniques, however, are based on ideas that were originally conceived hundreds, even thousands of years ago. In the field of authentication today, there are currently three methods to authenticate oneself to another person or a system.
