RE: W3C Credentials CG Call Tues: mobile DL deck

Thank you to Heather, Mike and Wayne (W3C Co-Chairs) for arranging this briefing.
Thank you to the UL folks for their briefing and their willingness to answer  the questions from the audience.

This was a very helpful, informative and educational session.

Without getting sidetracked into Standards Politics/Drama, I came away from this session with two specific points as it relates to Interoperability.


  *   The interface between the Issuing Authority (“Issuer”) and the Mobile Device (“Holder”) is deliberately out of scope of the ISO/IEC 18913-5 Standard. The impact of this choice is that it provides technology vendors the ability to lock in DMVs into their proprietary provisioning API while implementing this standard. I can foresee a messaging that will revolve around their future support of a future provisioning standard (ISO/IEC TS 23220-3), which will rapidly fall by the wayside of operational realties and budgets  i.e. If a DMV in the future asks them to support that as-yet-undefined-API/Standard, the vendor will almost certainly ask them for additional funding to implement that – with the DMV being loath to do so given that they already have an provisioning API (albeit proprietary) in place – the classic definition of vendor lock-in.
  *   The ISO standard also deliberately puts out of scope any standardized way to check the revocation / credential status of the mDL. Which means is that each vendor is implementing a proprietary mechanism for doing so that further locks in a DMV to a particular vendor.

At the same time, I saw some potential glimmers of a shared path towards interoperabilty:

  *   The VC API work that is an approach to a standardized API between an Issuing Authority and a Mobile and between the Mobile Device and the Verifier.
  *   If you combine the VC API with the “Model 2 Considerations” which speaks to a shared wallet (I have no idea what a “ISO Compliant App” is – so am not using that terminology) that can store both an mDL and a VC, with the VC also able to “Share QR and/or NFC functions” and “Share user interface, secured data storage”, that feels like a narrow path towards a possible interoperable future…


What did I get wrong above?
What did others in the community take away from the presentation?

Thanks to everyone for the engaging call yesterday, attached is the deck Arjan presented. mDL is gaining momentum in the states and while it may take a while to get utility scale coverage for its’ 230M people, it does hold the promise of a being a privacy preserving, portable, cryptographic identity credential that leverages an established and proven identity proofing ecosystem. With aspirations of expanding beyond the core ‘right to drive’ use cases and identity-specific credential issuance I believe ISO’s work could benefit greatly from the advances we are developing that addresses the myriad issues associated with broader use cases and adoption.

TL;DR: An overview of mDL

NEXT MEETING:
A few folks from UL have graciously agreed to get the CCG an overview of mDL
Topics Covered and open for discussion:
