After reading this thread I had the question on whether it is possible to verify you have certain information without revealing who you are to others.

Oh ok. Well the kind of information is stuff like whether an organization is doing/has xyz or if that person is part of certain departments or something.
You could verify, without transmitting their telephone extension or employee number. You could verify that they are the author of a particular document. I guess you could verify a company is doing a particular action by verifying with a multiple choice question or series of questions.
