Technologies de l'information — Méthodologies d'estimation des performances biométriques à l'aide de modèles statistiques

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.
