[WG-PEMC] Re: Spreadsheet shared with you: "PEMC Requirements Coverage"

It's interesting. But not practical. We need wallets to be accountable. Free and accountable does not compute. thx ..Tom (mobile) On Sat, Oct 21, 2023, 6:28 PM Salvatore D'Agostino wrote:

It's an interesting list but I'm unclear about the scope of the charter that supports it. Is there one?

From where I stand, I would like to see some things clearly stated:

1 - The Holder SHOULD be a semi-autonomous and delegatable agent of the subject. This would help to address the power asymmetry between Issuers and Verifiers vs. subjects.

2 - Verifiers MUST scope and sign their verification requests. Scope MUST include a purpose. The signature MUST be sufficient to keep the verifier accountable if they breach their stated purpose of the request.

3 - The process of unwitnessed online verification must be clear. For example, under what use-cases is the subject expected to use a user-agent (mobile or hosted) that is "certified" or otherwise controlled by some government or federated private entity. A *single-purpose* wallet controlled by an Issuer or Verifier and not used for interaction outside of that specific scope could, of course, be certified by either the Issuer or Verifier.

4 - Protocols for presentation to the Verifier must consider the cost and inconvenience of doing request verifications, making authorization decisions, and keeping logs for Verifier accountability. Verifiers SHOULD post a payment or deposit in order to prevent spam and offset these costs borne by the subject. We cannot assume that subjects have a choice or that verifiers always compete fairly for subject engagement.

5 - The essential components, including wallets, for use of government-issued credentials MUST be free and accessible to all. We expect that for paper credentials, don't we?
