Generally you would have a trusted arbitrator (Trent) who checks/authenticates 
the information 
and passes it along. I'm not sure if you're trying to ask how the information 
would be checked if 
the person was against it being shared (there's no simple way to check 
someone's weight 
through their computer, so I assume an actual observation must be made.)

Are the characteristics you described (age, weight, height) being used as 
theoretical objects to 
represent what might be the part of a password, or are you saying someone 
might use that 
information as a piece of a password (myname-birthyear, etc).

Sorry if my answer isn't what you wanted, the question wasn't too clear.
