Biometric Sample Quality G2-version completed for ISO/IEC 29794 Part 1: framework (reprinted in August 2016) ISO/IEC 29794 Part 6: iris image data Revision about to complete for ISO/IEC FDIS 29794 Part 4: finger image data the NFIQ2.0 report will be updated to reflect the changes in FDIS see: http://www.nist.gov/itl/iad/ig/development_nfiq_2.cfm the reference implementation will move to GITHUB Christoph Busch

Presentation Attack Detection 30107 parts Part 1 - Framework Elaine Newton status: IS - published Part 2 - Data formats Olaf Henniger status: 2nd DIS Part 3 - Testing and Reporting Michael Thieme status: FDIS Christoph Busch

Presentation Attack Detection - Part4 Sydney Title: Presentation Attack Detection: Profile for Evaluation of Mobile Devices Scope: guidance for presentation attack detection evaluation of personal mobile devices with local biometric authentication biometric module for mobile devices closed system (i.e. with no access to internal results) definition of a minimum set of PAI species (? will be aging quickly) definition of a minimum number of subjects out-of-scope: mobile devices with remote biometric recognition Editor: Mike Co-Editor: Pierre, Elaine Christoph Busch

G3 development Generation 3: 19794-1:201x Generation 3: - The common semantics amongst all parts will continue to form the Framework of Generation 3 - All parts will exist in a XML and/or binary version with a (revised) harmonized semantic Christoph Busch

G3 development Christoph Busch

G3 development Structure discussion in Sydney We continue to use CBEFF Tree structure discussion the need to have a tree structure would be application driven. Delegate this suggestion to WG2 to work on tree structured biometric data Tag Dictionary should list all tag names and description automatic tag definition is SC17 recommended best practice extension and can only at the deliberate extension points “…” tag table with the result of the automatic tagging negative experience in TC68 with automatic tagging call for contribution on the experience with automatic tagging Christoph Busch

G3 development Structure discussion in Paris We do not drop any of the essential content structure of G2 all the image format types of G2 will exist in G3 content of quality block and certification block will exist We will keep definition of all types (frontal, full frontal, token frontal etc.) in our base standard. this includes 3D types Christoph Busch

Recommendations WG3 - Special Groups RECOMMENDATION 3.19 – Constituting of WG 3 SG Terms of reference: The Special Group will discuss the harmonization of ISO/IEC 39794-1, -4, and -5 and the question how to avoid tag conflicts in the binary data interchange formats. RESOLUTION 3.21 – SC 37 to SC 27 Coordination Group Terms of reference: To coordinate SC 37 responses to SC 27 projects and liaison statements between meetings (based on relative timelines).
