PD ISO/IEC TR 49794:2022

What is ISO/IEC TR 49794 – Face image data and ID documents about?

ISO/IEC TR 49794 is a standard that covers face image data and ID documents enabling the integration and interoperability of data between different systems.

ISO/IEC TR 49794 provides transition examples from ISO/IEC 19794-4:2005 and ISO/IEC 19794-5:2005 formats to ISO/IEC 39794-4:2019 and ISO/IEC 39794-5:2019 formats for eMRTD application. ISO/IEC TR 49794 also provides an implementation example for the ISO/IEC 39794-6:2021 format.
ISO/IEC TR 49794 contains:

• Information for eMRTD issuers and eMRTD-reader vendors
• Summarized tables of data elements of ISO/IEC 19794-4:2005 and ISO/IEC 19794-5:2005 and ISO/IEC 39794-4:2019, ISO/IEC 39794-5:2019 and ISO/IEC 39794-6:2021
• Tag, length, value (TLV) data examples of ISO/IEC 39794-4:2019, ISO/IEC 39794-5:2019 and ISO/IEC 39794-6:2021 for implementation
• Tag lists of ISO/IEC 39794-4:2019, ISO/IEC 39794-5:2019 and ISO/IEC 39794-6:2021, and an extended example of ISO/IEC 39794-5 as informative annexes.

ISO/IEC TR 49794 also includes correspondence tables of data elements between ISO/IEC 19794-4:2005 and ISO/IEC 19794-5:2005 and ISO/IEC 39794-4:2019 and ISO/IEC 39794-5:2019, providing:

• Information on whether each data element is normative or optional
• Brief note of each data element from the viewpoint of transition.

Note: ISO/IEC TR 49794 does not cover:

• Second and later editions of the ISO/IEC 19794 series (2011 and after)
• 1 formats and XML formats specified in the ISO/IEC 39794 series

Who is ISO/IEC TR 49794 – Face image data and ID documents for? 

ISO/IEC TR 49794 on face image data and ID documents is useful for: 

• Government organisation
• Verification agencies
• Software industries
• Research and development team
• Biometrics companies

Why should you use ISO/IEC TR 49794 – Face image data and ID documents?  

Face images, fingerprints and iris patterns have been used for many decades to verify the identity of individuals. In recent years, digital face images have been used in many applications of automated face recognition. Photographic formats are standardized, for example for electronic machine-readable travel documents (eMRTDs), identity documents and driver's licences.

ISO/IEC TR 49794 provides you guidance on the transition of biometric data groups, including data groups for biometric data and internal consistency checking of data groups, ensuring accuracy and validity of the data systems.

ISO/IEC TR 49794 assists you in the implementation of data pertaining to finger image data, face image data, and iris image data.
ISO/IEC TR 49794 standardizes photographic formats for electronic machine-readable travel documents (eMRTDs), identity documents, etc.
Use and compliance with ISO/IEC TR 49794 can help in easier management of data for verification agencies and biometrics companies.
