Tool To Allow ISPs To Scan Every File You Transmit

timdogg writes "Brilliant Digital Entertainment, an Australian software company, has grabbed the attention of the NY attorney general's office with a tool they have designed that can scan every file that passes between an ISP and its customers. The tool can 'check every file passing through an Internet provider's network — every image, every movie, every document attached to an e-mail or found in a Web search — to see if it matches a list of illegal images.' As with the removal of the alt.binary newgroups, this is being promoted under the guise of preventing child porn. The privacy implications of this tool are staggering."

    Here's how CopyRouter would work, according to the company's slide show: A law enforcement agency would make available a list of files known to contain child pornography. Such files are commonly discovered in law enforcement raids, in undercover operations and in Internet searches that start with certain keywords (such as "pre-teens hard core"). Police officers have looked at those files, making a judgment that the children are clearly under age and that the files are illegal in their jurisdiction, before adding them to the list. Each digital file has a unique digital signature, called a hash value, that can be recognized no matter what the file is named, and without having to open the file again. The company calls this list of hash values its Global File Registry.
    Whenever an Internet user searched the Web, attached a file to an e-mail or examined a menu of files using file-sharing software on a peer-to-peer network, the software would compare the hash values of those files against the file registry. It wouldn't be "reading" the content of the files -- it couldn't tell a love note from a recipe -- but it would determine whether a file is digitally identical to one on the child-porn list. If there were no match, the file would be provided to the user who requested it. But if there were a match, transmission of the file would be blocked. The users would instead receive another image or movie or document, containing only a warning screen.
    The makers of CopyRouter claim that it can even be used to defeat encryption and compression of files in the Internet's Wild West: the peer-to-peer file-sharing tools such as Gnutella and BitTorrent.

It was my understanding that the present crop of file sharing tools provide obfuscation (ROT13 and the like) and not real encryption to set the bar just high enough to prevent packet inspection. However, it would not be difficult to implement stronger encryption methods (if they haven't done so already), should that prove necessary. In fact, the CopyRouter folks are at a distinct disadvantage in any encryption arms race since MITM and other cryptanalysis techniques are much more computationally expensive than the encryption itself AND the users outnumber the routers by thousands or even tens of thousands to one. The NSA might more credibly claim to be able to do this, but they have acres of underground super computers consuming as much electrical power as a small country, so I am very skeptical when anyone claims to be able to "defeat encryption" and doubly so when a private company mentions it as a bullet point in their power point presentation.

    Ok, on really simple protocols, like HTTP or FTP, maybe - but most, if not all, p2p traffic is safe, i think. This is of course because of the chunky nature of transmission - you can't really tell what part of the file went through your pipe just by looking at it, and since parts are sent at random, you cannot rebuild the file with your chunks without guiding information, be it a torrent file, a list of parts for emule, or whatever else there is. And you need the whole file to get your hash-check. That's one. Two: encryption totally kills the effort, as the ISP can in no way examine your file without interfering with your transfer, and SSL exists solely to protect you from this.

    Even if my line of thinking is really misguided here, this would require lots and lots of processing power - i mean, on a routing line with a hundred users on one end, it's thousands of hash-checks to be made for every stupid rebuilt file - both processes of course painfully CPU-eating, unless you want false-positives, since you didn't bother to use a proper hashing algorithm.

Common carrier rules have resolved the disputed issues of duty to serve, nondiscrimination, and interconnection. Facilities such as railroads, telegraphs and telephone companies were obliged either by common law or by legislation to implement an equal "duty to serve" regime. The history of common carrier duties illuminates three reasons supporting the imposition (and the occasional elimination) of those requirements.
