Which of the following metrics assess a biometric device’s performance when it attempts to authenticate subjects?
False Rejection Rate measures erroneous denials of legitimate identity claims, while False Acceptance Rate measures erroneous confirmations of fraudulent identity claims. The Crossover Error Rate (also called Equal Error Rate) is the operating point at which false-rejection and false-acceptance errors are equal; it is used to characterize biometric matching performance. NIST: false reject rate (FRR) and NIST: false accept rate (FAR).
