a large organization uses biometrics to allow access to its facilities. It adjusts the biometric value for incorrectly granting or denying access so that the two numbers are the same. What is this value called?
Correct Answer: C
Equal error rate is the value of the biometric system's threshold that results in the same false rejection rate (FRR) and false acceptance rate (FAR). FRR is the probability that the biometric system will reject a legitimate user, while FAR is the probability that the biometric system will accept an impostor. Equal error rate is used to measure the accuracy and performance of the biometric system, as it represents the point where the system is neither too strict nor too lenient. A lower equal error rate indicates a more reliable and secure biometric system. Accuracy acceptance threshold is not a term used in biometrics, but it could refer to the acceptable level of error for the biometric system. FRR and FAR are the types of errors that the biometric system can make, but they are not the value that is adjusted to make them equal.
