David,

Thanks for these points.

Here is a Wikipedia article on know your customer: https://en.wikipedia.org/wiki/Know_your_customer .

Here is a note I wrote on these topics: https://github.com/w3c/webauthn/issues/521 .

It’s possible that multiple justifications or supporting evidences can be of use in supporting a real name or date of birth, a set of verifiable claims.  This is an API topic pertinent to what is provided when a user is prompted to provide such data.  A multi-select GUI could be provided for users to provide parallel evidences.  We're accustomed to a driver’s license or passport sufficing; it could be that a dozen virtual documents, and claims from each, corroborate one another.

Hi Adam

You are correct in saying that VCs can easily enable users to present
their real names to web sites. The practical difficulty I envisage, at
least in the short term, is not in developing easy to use GUIs (I think
these already exist), but rather in getting an authoritative source such
as a government department to issue a VC containing your registered
name. Besides the bureaucracy that is involved in getting the government
to implement the VC technology, it is quite likely that no government
department has a correct list of all its citizens. It is well known that
some citizens have multiple SSNs, have different names in different
systems, and many systems do not have a complete register (e.g. passport
and driving licence systems). So who does the inspector trust?

If a site such as Facebook trusts a non-authoritative source to issue a
VC containing your name, then we are no better off, as fake news
providers will simply register a fake name with the non-authoritative VC
issuer.

Perhaps banks, who are now using very strong 'know your customer' rules
before they will open a new bank account, due to strong international
money laudering rules, could be the best option as a trusted issuer.

regards

David
