And This! Owner Free File System

Quoth the Treas, of Digg, here.

"Actually waterdragon, after taking your advice and googling OFF it seems that your explanation was wrong.

This is what I came up with:

'The argument goes something like this: a copyrighted file is converted into small chunks, which are labeled "A." These chunks are still copyrighted by the original owner. It is then encrypted by performing an XOR operation with a block of random numbers, called "B." The resulting block "C," is still copyrighted by the original owner, but things get really interesting when C is encrypted again, this time using not a series of random numbers, but a block "E" that is pulled out of the user's cache. Block E is itself the result of an encryption of someone else's copyrighted file (D), which would make the final result (F) copyrighted by two content owners at the same time. As it is not possible for both parties to hold a copyright on the same content, the result is that neither party does, and thus the block can be transmitted without fear of lawsuits from the RIAA or MPAA.'"

So, basically, you take the chunks of a movie and XOR them with some random data.

You do this for two movies, one of which you must already have.

You then XOR them with each other and send the file to your friend.

Essentially, you're using a movie as an encryption key. That's sick!
