Dear Group

Our documentation says that we need user-centric and privacy-enhancing
credentials (e.g.
but I cannot find anywhere where we state precisely what we mean by the
terms user-centric and privacy-enhancing in the context of verifiable
credentials. I think it would be a good idea to include these phrases in
our glossary of terms (http://opencreds.org/specs/source/glossary/)
along with our definitions.

So here are my initial proposals for these definitions:

user-centric - the user is in full control of the collection, storage
and use of his/her credentials

privacy-enhancing - the credentials do not reveal any personal
information about the user except that which the user specifically permits

Wrt to the last definition, I have an issue regarding the use of a
unique ID in credentials, and whether this is a correlating handle or
not. If it is, then the recipient could obtain personal information
about the user without his/her express permission, and then the
definition would not be accurate. Comments?
