Re: This is a use case

It depends. If all you care to solve is the creation of fake
digital certificates, then you can include the hash of a quantified face
photo in the VC and display the quantified face photo along with the QR
code that is the VC or links to the VC. This can be done with paper
vaccination credentials and the verifier does not need to call home or
check against any subject database.

Trust is still required between the issuers and verifiers (including across
borders) but the subject themselves need not be identified as part of that
federation.

I describe more of this here:
