Brightnets are Owner Free File Systems

elucido writes "OFF, or the Owner-Free Filesystem is a distributed filesystem in which everything is stored in reference to randomized data blocks, as opposed to a 1:1 copy of the original data being inserted. The creators of the Owner-Free Filesystem have coined a new term to define the network: A brightnet. Nobody shares any copyrighted files, and therefore nobody needs to hide away. OFF provides a platform through which data can be stored (publicly or otherwise) in a discreet, distributed manner. The system allows for personal privacy because data (blocks) being transferred from peer to peer do not bear any relation to the original data. Incidentally, no data passing through the network can be considered copyrighted because the means by which it is represented is truly random." Their main wiki page discusses a bit of what this means and how it might work as well. I've been saying that we need this for many years now, if only because we all have 10 gigs free on our machines and if we could RAID the internet we'd need fewer hard drives.

      Except that is probably bullshit to copyright lawyers

      There's a great explanation of why in this essay, What Colour are your Bits. It's actually about another system based on the same sort of ideas.

      http://ansuz.sooke.bc.ca/lawpoli/colour/2004061001.php

      The fallacy of Monolith is that it's playing fast and loose with Colour, attempting to use legal rules one moment and math rules another moment as convenient. When you have a copyrighted file at the start, that file clearly has the "covered by copyright" Colour, and you're not cleared for it, Citizen. When it's scrambled by Monolith, the claim is that the resulting file has no Colour - how could it have the copyright Colour? It's just random bits! Then when it's descrambled, it still can't have the copyright Colour because it came from public inputs. The problem is that there are two conflicting sets of rules there. Under the lawyer's rules, Colour is not a mathematical function of the bits that you can determine by examining the bits. It matters where the bits came from. The scrambled file still has the copyright Colour because it came from the copyrighted input file. It doesn't matter that it looks like, or maybe even is bit-for-bit identical with, some other file that you could get from a random number generator. It happens that you didn't get it from a random number generator. You got it from copyrighted material; it is copyrighted. The randomly-generated file, even if bit-for-bit identical, would have a different Colour. The Colour inherits through all scrambling and descrambling operations and you're distributing a copyrighted work, you Commie Mutant Traitor.

      To a computer scientist, on the other hand, bits are bits are bits and it is absolutely fundamental that two identical chunks of bits cannot be distinguished. Colour does not exist. I've seen computer people claim (indeed, one did this to me just today in the very discussion that inspired this posting) that copyright law inescapably leads to nonsense conclusions like "If I own copyright on one thing, and copyright inherits through XOR, then I own copyright on everything because everything can be obtained from my one thing by XORing it with the right file." That sounds profound only if you're a Colour-blind computer scientist; it would be boring nonsense to a lawyer because lawyers are trained to believe in and use Colour, and it's obvious to a lawyer that the Colour doesn't magically bleed to the entire universe through the hypothetical random files that might be created some day. You could create the file randomly, but you didn't. Maybe you could create a file identical to the complete works of Shakespeare by XORing together two files of apparently random garbage. "Why, so can I, or so can any man;" but that doesn't mean that I am William Shakespeare.

      It's not a form of encryption, the purpose is not to hide the data but to share representations. The basic idea is let's say that I have files/blocks A,B,C. Instead of storing them directly I will compute shares that merge the information into a new set of blocks. None of the new set of blocks will contain copyrighted info - or if it does then who will own it because there are competing copyright claims. To get file A back out I need to take a selection of the shares and xor them together.
