Information technology — Biometric performance testing and reporting — Part 10: Quantifying biometric system performance variation across demographic groups

This document establishes requirements for estimating and reporting on performance variations observed when cohorts belonging to different demographic groups engage with biometric enrolment and recognition systems. In this context, performance refers to failure-to-enrol rate, failure-to-acquire rate, shifts in comparison score, recognition error rates, and aspects of response and processing time (throughput). This document is applicable to the following: — demographic group membership; — using phenotypic measures; — reporting on tests; — stating statistical uncertainty estimates; — operational thresholds settings; — equitability; — procurement agency activities. This document also provides terms and definitions to be used when reporting performance variation across demographic groups. This document is applicable to: — technology evaluations of algorithms, subsystems and systems; — scenario evaluations of systems; — operational evaluations of fielded systems. Application of this document does not require detailed knowledge of a system’s algorithms but it does require specific knowledge of the demographic characteristics for the population of interest.

Information technology — Biometrics — Overview and application

This document describes the history and purpose of biometrics, the various biometric technologies in general use today (for example, fingerprint recognition, face recognition and iris recognition) and the architecture of the systems and the system processes that allow automated recognition using those technologies. It provides information on the application of biometrics in various business domains, such as border management, law enforcement and driver licencing. It also provides information on the societal and jurisdictional considerations that are typically taken into account in biometric systems. Additionally, this document provides guidance on the use of the International Standards that underpin the use of biometric recognition systems.

This document establishes the following items for any or all biometric sample types as necessary: — terms and definitions that are useful in the specification and use of quality measures; — purpose and interpretation of biometric quality scores; — motivation for developing biometric sample datasets for the purpose of quality score normalization; — format for exchange of quality assessment algorithm results; — methods for aggregation of quality scores; — methods for evaluating the efficiency of quality assessment algorithms. The following are outside the scope of this document: — specification of minimum requirements for sample, module, or system quality scores; — standardization of quality assessment algorithms; — assessment of utility of biometric samples or references for human examiners.

Information technology — Use of biometrics in video surveillance systems — Part 1: System design and specification

The ISO/IEC 30137 series is applicable to the use of biometrics in VSSs (also known as closed circuit television or CCTV systems) for a number of scenarios, including real-time operation against watchlists and in post-event analysis of video data. In most cases, the biometric mode of choice will be face recognition, but this document also provides guidance for other modalities, such as gait recognition. This document: — defines the key terms for use in the specification of biometric technologies in a VSS, including metrics for defining performance; — provides guidance on the selection of camera types, placement of cameras, image specification, etc., for the operation of a biometric recognition capability in conjunction with a VSS; — provides guidance on the composition of the gallery (or watchlist) against which facial images from the VSS are compared, including the selection of appropriate images of sufficient quality, and the size of the gallery in relation to performance requirements; — makes recommendations on data formats for facial images and other relevant information (including metadata) obtained from video footage, used in watchlist images, or from observations made by human operators; — establishes general principles for supporting the operator of the VSS, including user interfaces and processes to ensure efficient and effective operation, and highlights the need to have suitably trained personnel; — highlights the need for robust governance processes to provide assurance that the implemented security, privacy and personal data protection measures specific to the use of biometric technologies with a VSS (e.g. internationally recognizable signage) are fit for purpose, and that societal considerations are reflected in the deployed system. This document also provides information on related recognition and detection tasks in a VSS, such as: — estimation of crowd densities; — determination of patterns of movement of individuals; — identification of individuals appearing in more than one camera; — use of other biometric modalities such as gait or iris; — use of specialized software to infer attributes of individuals, e.g. estimation of gender and age; — interfaces to another related functionality, e.g. video analytics to measure queue lengths or to provide alerts for abandoned baggage.

Information technology — Biometric presentation attack detection — Part 4: Profile for testing of mobile devices

This document is a profile that specifies requirements for testing biometric presentation attack detection (PAD) mechanisms on mobile devices with local biometric recognition and on biometric modules integrated into mobile devices. The profile lists requirements from ISO/IEC 30107-3 that are specific to mobile devices. It also establishes requirements that are not present in ISO/IEC 30107-3. For each requirement, the profile defines an “Approach in PAD Tests for Mobile Devices”. For some requirements, numerical values or ranges are provided in the form of best practices. This profile is applicable to mobile devices that operate as closed systems with no access to internal results, including mobile devices with local biometric recognition as well as biometric modules for mobile devices. This document is not applicable to mobile devices with solely remote biometric recognition. The attacks considered in this document take place at the capture device during the presentation and collection of biometric characteristics. Any other attacks are outside the scope of this document.

Biometrics — Identity attributes verification services — Part 2: RESTful specification

The ISO/IEC 30108 series defines biometric services used for identity assurance that are invoked over a services-based framework. It provides a generic set of biometric and identity-related functions and associated data definitions to allow remote access to biometric services. Although focused on biometrics, the ISO/IEC 30108 series includes support for other related identity assurance mechanisms such as biographic and document capabilities. Identity attributes verification services (IAVSs) are intended to be compatible with and used in conjunction with other biometric standards as described in ISO/IEC 30108-1. This document implements the specification provided in ISO/IEC 30108-1 using representational state transfer (REST). Specification of biometric functionality is limited to remote (backend) services. Services between a client-side application and biometric capture devices are not within the scope of this document. Integration of biometric services as part of an authentication service or protocol is not within the scope of this document.
