Standards – a Synergy with ISO/IEC

ISO/IEC JTC1 SC37 Working Group 3 – Biometric Data Interchange Formats recently met last July to discuss a number of relevant standards. Want to know more about which standards iMARS has been working on and what was discussed in the standardisation meeting? Continue reading.

iMARS partners have commented on ISO/IEC 29794-1 Biometric sample quality – Part 1: Framework Working Draft 1 & 2. This included various comments on the new error versus discard characteristic (EDC) curves, which are reporting the accuracy of a quality metric, extending the respective clauses (formulation/fixes), introduction of an EDC Python example script (informative annex) and miscellaneous comments, i.e. explicitly defining that “higher quality score values imply higher biometric utility”. WG3 will revise ISO/IEC 29794-1 Biometric sample quality – Part 1: Framework as a committee draft (CD). Biometric sample quality forms, in addition to the (extensible) biometric data interchange formats, a important working area of the group.Revision project ISO/IEC 29794-5 Biometric sample quality – Part 5: Face image data is very relevant to operational biometric systems. This part, formerly a technical report, is now under development as an international standard and will relate to quality requirements from ISO/IEC 19794-5:2011 and ISO/IEC 39794-5:2019. This standardization project will provide measures to decide whether a facial image is of sufficient utility for various application scenarios. The document is distributed as the third Working Draft (WD) and seeking more contributions. iMARS research results, in particular the results of Work Package 11, will contribute to the revision of ISO/IEC 29794-5 Information technology – Biometric sample quality – Part 5: Face image data.

WG1, WG2, WG3, and WG5 discussed revision project ISO/IEC 30107-3 Biometric presentation attack detection – Part 3: Testing and reporting, in a joint meeting. The discussion confirmed the relevance of the new Relative Impostor Attack Presentation Accept Rate (RIAPAR), which is essential for understanding vulnerabilities of biometric systems about presentation attacks. The project was promoted to Draft International Standard (DIS) level.

Moreover, it was decided to start the revision project of ISO/IEC 30107-1 Biometric presentation attack detection – Part 1: Framework. The intention is to incorporate the concept of bona fide into the PAD taxonomy. This task is aligned with the vulnerability analysis developed by WP2, WP5 and WP7 of iMARS. Moreover, the testing methodology, Morphing Vulnerability Rate (MVR), regarding vulnerability testing of face recognition systems concerning morphing attacks will be contributed to a new part of ISO/IEC 30107.

Apart from the advancements in standards, the iMARS consortium has been meeting periodically to prepare a contribution to the Harmonized Biometric Vocabulary (HBV). This contribution will contain a clear definition of morphing attacks versus manipulation attacks.
