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.
