The false acceptance rate, or FAR, is the measure of the likelihood that the biometric security system will incorrectly accept an access attempt by an unauthorized user. A systems FAR typically is stated as the ratio of the number of false acceptances divided by the number of identification … See more In the identification case, the system is trained with the patterns of several persons. For each of the persons, a biometric template is … See more Due to several reasons, this assumption isnt true for real world biometric systems. In some cases impostor patterns generate scores that are … See more The choice of the threshold value becomes a problem if the distributions of the client and the impostor scores overlap, as shown in the next image on the left. On the right, the … See more Depending on the choice of the classification threshold, between all and none of the impostor patterns are falsely accepted by the system. The threshold depending fraction of the falsely accepted patterns divided by … See more WebThe following are used as performance metrics for biometric systems: False match rate (FMR, also called FAR = False Accept Rate): the probability that the system incorrectly …
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.
