Is it possible to create something where knowing about the thing constitutes copyright infringement?

Both, obviously.

But you don't make it public you did that. If summoned to court, you XOR C with innocuous file D, to get result E, which looks like a random encryption key. Then you tell them the file is D XOR E.

It helps if either A or B is random. There's no chance that your randomly encrypted file is accidentally the XOR of two non-random files.
