        I don't think this goes far enough in terms of protections for users
        against the potential abuse of something that might be able to
        individually and persistently identify them on the Internet. First,
        it's not clear what network layer identity means in this context. I
        hope it refers to an ad hoc collection of identifiers as opposed to
        the identity of individual users or devices. In any case maybe a
        definition of identity might be in order here. Secondly, I think it
        should be stated up front that identity cannot in any way be used to
        identify individual users, it cannot be used to create a global
        database of Internet users, in no way can it be used by networks or
        governments to track or block individuals, nor can it ever be required
        for communications. That implies network layer identities cannot
        contain PII (personally identifiable information) and cannot be
        permanently assigned to users or devices (in the same spirit that
        Ethernet addresses were removed from IIDs because of privacy
        concerns).

        Thanks,
        Tom

    When it comes to these concerns I’d strongly recommend to have a look at how identity attributes were exchanged and trust established within the ABFAB framework (https://tools.ietf.org/wg/abfab/)

    [Uma]: Though  this is not about SSOs or application stuff, thanks for the pointer.
                    I always believed EAP has a role to play for IDy auth procedures and lot of concerns brought out here (especially related to Identity-privacy) are effectively taken care with existing mechanisms.

ABFAB was not about SSO, but about using user identities to allow their access to network services while protecting user privacy. And among those services you could consider any kind of application or connectivity service…

Be goode,
