WebOct 31, 2024 · One way to summarize the operating characteristics of a biometric security system is to look at the Crossover Error Rate (CER), also known as the Equal Error Rate ( EER ). The system has parameters that can be tuned to adjust the FAR and FRR. Adjust these to the point where the FAR and FRR are equal.
WebMay 28, 2015 · As you can see, there are two error rates: FAR (False Accept Rate) and FRR (False Reject Rate). FAR is calculated as a fraction of impostor scores exceeding your threshold.
