Abstract

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.

This standard contributes to the following Sustainable Development Goals
