This reminds me of a question I heard long ago: if you take a copyrighted material A and XOR it with another material B, and then you distribute the result C, who can claim infringement if at all? The company which owns A or the one which owns B?
Especially that in order to actually claim infringement it means company A obtained a copy of the material of B in order to verify C infringes their rights.
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.
Interesting. Very similar to the copyright logjam which Jim Sterling tries to create in Youtube. Basically uses copyrights of several companies and when they all claim ownership, then none of them can monetise the video.

Both, obviously.
