Information technology — Methodologies to evaluate the resistance of biometric systems to morphing attacks

Edition date: 2025-08-25
In Force
Available languages: English
Summary:

This document establishes a methodology to evaluate the resistance of BSs to morphing attacks, including multiple identity attacks. The document is limited to image-based morphing attacks. The term "image-based" includes modalities such as face, iris and finger image data.

The document establishes:

—     a definition of biometric sample modifications and manipulation with a specific focus on manipulations that constitute a multiple identity attack. This can be, for instance, an enrolment attack with face image morphing;

—     a methodology to measure the morphing attack potential of a morphing method.

The document also describes how morphing algorithms can be used for system evaluation.
