What good is all this?

Suppose I want to prove my identity to strangers

I can make up and publish an HC problem for which I know the answer

Then I can prove that I'm me by proving that I know the answer to the problem

Eavesdroppers can't gather any information that helps them impersonate me

V can't turn around and pretend to be me either
