WebThe false accept rate (FAR) and false reject rate (FRR) are two important metrics that can be used to evaluate the performance of a biometric system. These rates are typically configured in software by adjusting the system’s threshold value. As you can see, the FAR and FRR will affect the security level of a biometric system.
