What kind of biometrics utilizes a person’s unique physical characteristics for authentication such as fingerprints or unique characteristics of a person’s face?

The block diagram illustrates the two basic modes of a biometric system. First in verification (or authentication ) mode the system performs a one-to-one comparison of a captured biometric with a specific template stored in a biometric database in order to verify the individual is the person they claim to be. Three steps are involved in the verification of a person .
