Biometrics
Biometric verification is a process through which a person can be uniquely identified and authenticated. In this method, an individual is identified by verifying one or more of their biological features. Examples of biometric identifiers include a palm print, hand geometry, fingerprints, retina and iris patterns, voice, and DNA.
Biometrics Accuracy Measure
The accuracy of a biometric system determines how well it meets the objective of secure and reliable access control. Accuracy measures determine the success factor of the biometric system. A few biometrics accuracy measures are discussed in detail in the following subsections.
False Acceptance Rate (FAR)
This is the rate of acceptance of a false person, that is, an unauthorized person. 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).
