Interesting -- I tend to think it fits that case better, especially
thinking of it in terms of how other types of information are shared on
the Web. People typically "share" their own data on the Web.

Why? Because of the surrounding word choice and grammar? With tweaks for
Sharer, you get:

A Sharer may share Claims with a Verifier. For example, sharing your
digital driver's license with a police officer.

That sounds perfectly reasonable to me.

The term "information sharing" is quite commonly used in relation to
rights and regulations. I don't think saying that someone is the sharer
of information fails to convey that there may potentially be some
authorization requirements involved in the act of sharing.
