I think it goes something like this: The document/avatar/code/whatever has a crypto identifier embedded in it that can be extracted to verify ownership. Perhaps a good analogy might be a steganographic application.
The problem is this: Is there a way for a user to "view" the client's avatar (and in this sense, the user usually has to receive a copy of the code to render the avatar and render it on the local machine) but not save a copy? Assume that a client with no save feature is not a viable option...too easy to work around.
Yep. Even the "eyes only" setting in PGP is no good if the recipient is savvy enough to cut and paste the plaintext to the clipboard. -- Sincerely, AJ Barrett <abarrett@checkfree.com> Product Analyst CheckFree Corporation: The Way Money Moves http://www.checkfree.com
