False rejection biometrics
WebBiometrics are body measurements and calculations related to human characteristics. Biometric authentication (or realistic authentication) is used in computer science as a … Webwhere in Eq. (1), False Accept Rate (FAR) is the percentage of misclassified real fingerprints and FRR (False Reject Rate) is the percentage of misclassified as fake ones. FAR and FRR can be expressed as: (2) (3) The value of ACE ranges from 0 to 100. In addition, the smaller the ACE is, the better the performance is.
