I noticed that in the meeting notes for this topic nobody talked about how this would work on mobile devices - it sounded like people were thinking about desktop OS/browser implementations.
I'm learning more about the sandboxing and other restrictions on mobile devices - and how this prevents / controls native app invocation and discovery in ways that force use of OS/mobile browser facilities, and precludes use of third party systems.

Does anyone else observe similar things?

Hi, 

as far as I’m informed, the WICG just incubated the credential topic last week and will be pursuing a process to come up with a consolidated proposal for a browser API. I think the proposals on the table are a great staring point but are a bit narrow (esp. the Mobile Document Request API). A solution should support the credential formats that can be found in the market and not limit implementers. I have argued to specify an API that focuses on wallet discovery and invocation as I believe those are the core challenges current protocols for credential issuance and presentation are facing.  

I think we need to carefully watch the further development and contribute. 

best regards,
Torsten.

Apple has specificed the Mobile Document Request API, which is a new web API that allows websites to request a mobile document as defined in ISO/IEC 18013-5.
 

Is this something that should be considered by the OpenWallet Foundation – or is it already under consideration? (I’m asking because I’ve missed most of the OWF architecture meetings since they occur at night CET, so this may have been discussed already.)

 

Kind regards,

I’m unfamiliar with the various protocols for issue and presentation of VCs but I’m under the impression that many of them make assumptions about whether the user agent is a browser or an app. I believe IETF GNAP is intentionally designed to work securely with both. Is this a consideration we can use to categorize the various protocols options?

There appear to be critical differences between the “Mobile Document Request API” (Originally proposed by Apple but also supported by Google at that time) and the “Identity Credential” work (proposed by Google).

 

The following is my understanding in non-spec-speak (which may be incomplete or wrong, so would appreciate corrections):

 

Both seek to define a standardized way for a browser to present digital credentials stored in a digital wallet to a web site; this is good
Potentially competes with or could serve to enhance any web based credential presentation protocols
 

Then they go their separate ways …

 

Mobile Document Request API

Supports only ISO/IEC 18013-5 mDLs
Marks as being ‘out-of-scope’ the manner in which the browser interacts with the digital wallet. Implications of this are profound in that If you are a platform that has a digital wallet (Apple Wallet / Google Wallet / Microsoft Authenticator? ) AND are also a browser vendor (Safari / Chrome / Edge), the platform gets to connect their wallet to their browser because that connection is not open but under their control.

Support multiple credential types (gratified to see prototype/demos of both mDL and W3C VCs in the presentation)
Support for multiple wallets << I am making an assumption here that ensuring this support requires standardizing and opening up the API connecting the wallet to the browser; which, if true, is A.Good.Thing!
 

This is my understanding of the primary differences … Corrections welcome!

Someone recently told me that https://developer.apple.com/wallet/get-started-with-verify-with-wallet/ had an update to say something about the Mobile Document Request API and third party applications. I think that may be of interest to people here.

Yes, so, the "Identity Credential" API proposal is closely based on Apple's Mobile Document Request API but - for a multitude of reasons - we wanted to change the API so it isn't tied to mdoc/mDL credential format. I obviously can't speak for Apple but my read is that they are OK with this change and will continue to participate in the WICG.

The last point about support for multiple wallets, yes, Chrome has made statements about this being a goal for the implementation of Chrome on Android (see https://groups.google.com/a/chromium.org/g/blink-dev/c/O9A9fq-0IdI/m/sqdVA17iBQAJ) and this is also how you could read Apple's page linked to in the paragraph above.

We are starting to make this API available behind flags in Android and Chrome so RPs and Wallets can experiment with it. The attached presentation is what we shared with ISO SC17 WG10 (the ISO WG working on Mobile Driving Licenses and 18913-5 and -7) and has more information about how we think this API could work on Android. There's nothing mdoc/mDL specific about this API and any Android application can be a credential provider for this API.

Hope this clarifies!

Thanks,
David

Hi David,

 

Request for one additional clarification as people a whole lot smarter pointed out to me that there is a gap in the current proposal for supporting “web wallets” i.e. web app based wallets as opposed to wallet applications on mobile devices, as that functionality appears to be missing in the current proposal.

 

Speaking to the needs of my organization, we are very interested in ensuring that both web and native wallets are equally supported.

 

What is Google’s intention/perspective regarding support for both in the work you are putting forward?

 

Best Regards,

 

Anil
