Biometrics
Biometric verification is a process through which a person can be uniquely identified and authenticated by verifying one or more of their biological features. Examples of these biometric identifiers include a palm, hand geometry, fingerprints, retina and iris patterns, voice, and DNA.
Biometrics – accuracy measure
The accuracy of a biometric system determines how well a system meets the objective. Accuracy measures determine the success factor of the biometric system. In this section, we will discuss a few biometrics accuracy measures.
False acceptance rate
The false acceptance rate (FAR) is the rate of acceptance of unauthorized users. For example, biometric controls will not restrict unauthorized people.
For example, if biometrics allows access to an unauthorized person, then it is referred to as a false acceptance.
False rejection rate
The false rejection rate (FRR) is the rate of rejection of the correct person (that is, an authorized person...
