Full title and description

Information technology — Biometric performance testing and reporting — Part 2: Testing methodologies for technology and scenario evaluation — Amendment 1: Testing of multimodal biometric implementations. This amendment (amd1-2015) extends ISO/IEC 19795-2:2007 with requirements, definitions and reporting rules needed to evaluate multimodal biometric devices and systems, including enrolment metrics, fusion-level considerations and requirements to support repeatable technology and scenario evaluations.

Abstract

This document is an amendment to ISO/IEC 19795-2:2007 that adds specific guidance and requirements for testing multimodal biometric implementations. It defines multimodal-specific performance measures (for example Multimodal Failure to Enrol), specifies how to collect and combine biometric data from multiple modalities, describes fusion-level considerations (sample, feature, score and decision levels) and sets out reporting requirements to improve repeatability and comparability of technology and scenario evaluations. The amendment is intended to make evaluations of combined-modality systems more rigorous and reproducible.

Scope

The amendment updates the scope of ISO/IEC 19795-2 to add multimodal biometric specific requirements for both technology evaluation and scenario evaluation. It requires explicit description of multimodal device and system structure, defines multimodal performance measures, specifies methods for biometric data collection and performance calculation when multiple modalities are involved, and specifies reporting requirements (including details on fusion functions, sensor configurations and presentation sequencing) needed to achieve repeatable and comparable test results.

Key topics and requirements

• Multimodal-specific requirements for technology evaluation and scenario evaluation (definition of test configurations and constraints).
• Introduction of multimodal enrolment and performance measures (e.g., Multimodal Failure to Enrol, fusion-aware false accept/reject metrics).
• Identification and documentation of fusion levels: sample-level, feature-level, score-level and decision-level fusion and their impact on test methods.
• Requirements for consistent data collection, template combination and reporting to ensure repeatability and comparability of results across systems and laboratories.
• Specification of sensor and presentation types (single integrated sensor vs multiple sensors; simultaneous vs sequential acquisition) as test variables affecting results.
• Detailed reporting obligations for fusion algorithms, subsystem configurations and enrolment/presentation policies to support meaningful interpretation of results.

These topics aim to ensure that multimodal evaluations produce sufficiently detailed and reproducible results for technology developers, test laboratories and procuring organisations.

Typical use and users

Primary users include biometric system vendors (for internal R&D and validation), independent test laboratories and certification bodies (for structured technology and scenario evaluations), procurement teams and integrators (for comparing candidate multimodal solutions), and researchers studying multimodal fusion and performance. The amendment is used when a test programme must explicitly address the additional complexity introduced by combining two or more biometric modalities.

Related standards

This amendment is part of the ISO/IEC 19795 series (performance testing and reporting) and should be considered alongside ISO/IEC 19795-1 (Principles and framework), modality-specific guidance in ISO/IEC TR 19795-3, operational evaluation methods in ISO/IEC 19795-6 and related vocabulary/biometrics standards (for example ISO/IEC 2382-37). Users evaluating multimodal systems will often consult those parts in combination with this amendment.

FAQ

Q: What is this standard?

A: It is Amendment 1 (2015) to ISO/IEC 19795-2:2007, providing additional procedures and requirements specifically for testing multimodal biometric implementations (i.e., systems combining two or more biometric modalities).

Q: What does it cover?

A: The amendment covers multimodal-specific testing methodology updates: definitions, enrolment and performance measures for multimodal systems, how biometric data from multiple modalities should be collected and combined for evaluation, fusion-level considerations, and expanded reporting requirements to enable repeatable technology and scenario evaluations.

Q: Who typically uses it?

A: Vendors, test laboratories, certification bodies, systems integrators, procurement authorities and researchers who need to design, execute or interpret biometric tests that involve multimodal systems.

Q: Is it current or superseded?

A: The document is an amendment published in 2015 to the 2007 edition of ISO/IEC 19795-2. As an amendment it modifies and complements the 2007 Part 2 text; users should confirm the current national or ISO catalogue status with their national standards body or the ISO/IEC catalogue for any later revisions or superseding publications.

Q: Is it part of a series?

A: Yes — it is part of the ISO/IEC 19795 series (biometric performance testing and reporting). Relevant parts include ISO/IEC 19795-1 (principles and framework), ISO/IEC TR 19795-3 (modality-specific testing guidance) and other parts addressing operational evaluation and interchange formats; these documents are typically used together when planning comprehensive biometric evaluations.

Q: What are the key keywords?
