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.
