That's called encryption using a one time pad.

That's one way of looking at it. Note that you can easily extend it to multiple people holding multiple keys, so that a=b^c^d^e, etc.

My point was that encrypting a copyrighted work does not remove the copyright from it; the result is still copyright and not legally redistributable.

I think the topic is “evidence of infringement is no longer readily available” not “suddenly, there is no infringement!”

The evidence of infringement would be apparent when b and c were colocated and there was a utility next to them for XORing files and piping it into VLC

I didn't read it that way - the OP said "liability", after all, not "detection".

But, meh, could just be he meant "won't get caught" and not "liability"; I make mistakes in comms all the time, after all.

Maybe, but b and c are indistinguishable from pure noise.

> Maybe, but b and c are indistinguishable from pure noise.

That's the whole point of encryption.

Right. But the copyright was violated when you used 'a' to begin with.
