- I just don't see what the big deal is. You'll never meet me. You
- can't care what I look like much less what genes I have. If you were to
- know, would that make my identification any more positive?
-
-
- If I give you an RSA key, that's all you need. I'm the only one in the world
- who knows the two primes in N. That defines *me*. Balding head or not,
- height, weight, ..., even gender is all irrelevant.
-
- I can prove I know those primes by signing something. You can verify that
- I know the primes, without learning the primes -- therefore without becoming
- able to pretend to be me.
-
- What more do you want?
