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."
This will cause huge latency issues and cost beaucoup bandwidth. ISPs would be shooting themselves in the foot if they did this with all traffic. OTOH, I could see laws requiring such tools for P2P traffic -- in fact that may well be inevitable, with the **AA's "ruling class" status these days.

Wasn't that the Aussie spyware company attached to Sharman Networks/KaZaA?
Before it got raided, I mean?
I call shenanigans.
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.
All in all, this looks to me like a terrible waste of money.

It looks like someone switched sides but taking a closer look they only seem to be in charge of the adware that came with Kazzaa, so I guess they were always evil.
Not only that, but it says that it works against movies.
The ISP downloads the entire 1-5GB file, hashes it, compares the hash, and then if it passes sends the file on to the user?
I think that would break almost every kind of application, and could easily be used to swamp the downstream of the ISP by making requests and then dropping the connection.
And then what about hash collisions, or programs that aren't web browsers?
If I have nothing to hide, don't search me
Exactly. They claim that the can search "every document attached to an e-mail .. -- to see if it matches a list of illegal images. Apparently, they have never heard of SMTP-TLS, POP3S, etc.. Or perhaps they have and they are just like many others -- selling snake oil.

Every time this topic comes up, someone posts something about how this could remove the common carrier status of ISPs.
Repeat after me: ISPs do not have common carrier status.
No. RTFA. CopyRouter merely pretends to be a server and tells the client the client to send data unencrypted. Bittorent just needs to upgrade it's encryption mechanisms.
And good luck trying to teach a jury about hash collisions.
not quite. they use packet forgery to turn off the encryption request, so it looks like the requester asked that the file be transmitted in plaintext. (and then they cross their fingers and hope noone notices).
this differs from a standard MITM attack: there, the attacker wants the encryption to proceed (in such a way that the attacker gets a copy of the key as well).
Heh, you're right "common carrier" does not seem to be explicitly defined by treaty (ie: it's more of a tradition than a rule) - found this on the WIPO site...
"63 The concept of a "common carrier," dating from 16th century English common law, captures private entities that perform public functions. Since at least the middle ages, most significant carriers of communications and commerce have been regulated as common carriers. 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. Common carrier duties have been imposed variously upon theories of de facto and de jure monopoly, on the theory that the enterprise had become "essential," and upon theories that the enterprise was publicly concerned in a particular manner (See James B. Speta, A Common Carrier Approach to Internet Interconnection, 54 Fed. Comm. L.J. 225 (2002) (surveying the history of common carriers and arguing that the same reason justify a general interconnection obligation for Internet carriers)."
