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 (FAR)
This is the rate of acceptance of a false person (that is, an unauthorized person). Biometric control will not restrict the unauthorized person.
For example, if biometrics allows access to an unauthorized person, then it is referred to as false acceptance.
False rejection rate (FRR)
This is the rate of rejection of the correct person (that is, an authorized person). Biometrics will reject even an authorized...
