This document provides statistical methodologies to estimate false match rates (FMRs) from small biometric sample sets. This document intends to: — lay out a methodology for biometric performance estimation based on extrapolation using extreme value statistical models; — provide statistical methodologies to estimate FMRs of biometric verification systems; — be applicable to systems that include algorithms that produce likelihood dissimilarity or similarity scores; NOTE Throughout the document, if not otherwise specified, scores refer to similarity scores. — specify the methodology for data recording and result reporting; — introduce metrics for the estimated biometric performance. The following are not within the scope of this document. — Estimation of false positive identification rates for one-to-many implementations. — Estimation of false accept rates for verification transactions.
