Information technology — Biometric performance estimation methodologies using statistical models ISO/IEC 5152:2024

Publication date:   Jul 11, 2024

Scope

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.
