You are talking about copy detection (where the original creator's name has 
been remove/changed) which is as you say is hard to do since it is too easy 
to defeat.

I was talking about detecting modifications done by someone other then the 
original creator.  Signing the prim would only stop someone from 
making/changing a prim/notecard and setting the creator to someone else.  
With public/private keys only the true creator can sign new/changed prims.

There was a case in SL where someone used a full-perm notecard created by a 
well known content creator and replaced the contents, then distributed that 
new notecard to a lots of people to make it look like the original creator 
was saying the things in the notecard.  People can use this to grief another 
user.
