Not unless you start using cryptographic keys or some other
authentication tool so that you can say X is really X. This opens a
can of worm, namely needing control over the hardware and so on and so
forth.

Probably a better idea is to have registries of content with
cryptographic timestamping so that author A can legally say work X is
really his/her own work, was released on date D with licence L, etc,
etc.

Can you explain this a bit more? How would a search agent be able to check whether a given file truly contained CC-licensed content?
