Hmm, it only took me a few minutes to figure out one way to do it, at least for a computer professional like myself. Input is easy, all you need is prior access to puzzles so they can be solved, which is also easy if you think about it.

Certainly you can detect the more obvious users, but I don't see any way to eliminate the possibility other than handing out unique puzzles every time.
