If you xor some data with random numbers, both the result and the random numbers are indistinguishably random and there is no way to tell which one came out of a random number generator and which one is "derived" from a copyrighted work. But if you xor them together again the copyrighted work comes out. So if you have Alice distribute one of the random looking things and Bob distribute the other one and then Carol downloads them both and reconstructs the copyrighted work, have you created a scheme to copy whatever you want with no infringement occurring?

Of course not, at least Carol is reproducing an infringing work, and then there are going to be claims of contributory infringement etc. for the others if the scheme has no other purpose than to do this.

Meanwhile this problem is also boring because preventing anyone from being the source of infringing works isn't a thing anybody has been able to do since at least as long as the internet has allowed anyone to set up a server in another jurisdiction.
