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 palm or 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. This section will present a few biometric accuracy measures.
False Acceptance Rate
False acceptance rate (FAR) is the rate of acceptance of a false person (that is, an unauthorized person). In this case, a biometric control does not restrict an unauthorized person and allows them access.
False Rejection Rate
False rejection rate (FRR) is the rate of rejection of a correct person (that is, an authorized person). In this case, biometrics reject even an authorized person, denying them...
