Information technology — Use of biometrics in video surveillance systems — Part 1: System design and specification (Adopted ISO/IEC 30137-1:2019, first edition, 2019-05)
Standards development within the Information Technology sector is harmonized with international standards development. Through the CSA Technical Committee on Information Technology (TCIT), Canadians serve as the SCC Mirror Committee (SMC) on ISO/IEC Joint Technical Committee 1 on Information Technology (ISO/IEC JTC1) for the Standards Council of Canada (SCC), the ISO member body for Canada and sponsor of the Canadian National Committee of the IEC. Also, as a member of the International Telecommunication Union (ITU), Canada participates in the International Telegraph and Telephone Consultative Committee (ITU-T).
At the time of publication, ISO/IEC 30137-1:2019 is available from ISO and IEC in English only. CSA Group will publish the French version when it becomes available from ISO and IEC.
This Standard has been formally approved, without modification, by the Technical Committee and has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.
The ISO 30137 series is applicable to the use of biometrics in VSS (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.
— defines the key terms for use in the specification of biometric technologies in a VSS, including metrics for defining performance;
— provides guidance on 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 watch list 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;
— determining 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 other related functionality, e.g. video analytics to measure queue lengths or to alert for abandoned baggage.
