Japanese P2P Users Arrested, Creator Targeted 205

Posted by simoniker from the stomp-the-miscreants dept.
nutznboltz writes "According to a story on CNET Asia, two Japanese users of the Winny P2P application have been arrested for copyright violations, and the developer of the P2P software has also had his home searched by police. Winny was 'supposedly anonymous', and purported to be based on Freenet, although Freenet creator Ian Clarke is claiming that Winny is not really like Freenet, and that he's 'not concerned that the Japanese police have somehow found a way to compromise Freenet's security'."

    Considering the un-userfriendly state Freenet is right now (not being able to "search the [free]net") it would have been a huge accomplishment to completely base a P2P software on it. So my guess is that Winny more or less just mention Freenet for recognition purposes.

      This is a complicated issue without a clear answer.

      If you want to be theoretical, then yes, Freenet does not provide anywhere near "absolute" anonymity. In fact, it doesn't even provide the level of anonymity that is used when judging such things as anonymous remailers or mixnets.

      Basically, Freenet purports to be "anonymous" because you files do not recide on the computer of the person who uploaded them, and because all downloads and uploads are chained and tunneled through each host involved in the transfer. That means that the host you download a Freenet document from just knows it got it from some other node, which got it from some other node, which got it through some other node, all the way back to the person who uploaded it. It certainly makes tracking the people upload and download things more difficult then on networks like Kazaa (where it is, as we have seen, trivial) but in theory, and with enough resources, it is of course not impossible.

      It should be noted what Freenet does NOT provide however. Freenet does do what the serious mixnets reffer to as "Onion routing", which basically means that the message is wrapped in an onion of cryptographic layers, which are pealed off at every step. The idea behind this is only the very last node can see contents of the message, and only the first knows it came from you (and none of the other nodes know anything except where the message came from and where it went).

      If you request something from Freenet, your node will call up another node and ask it for that file - if that node is controlled by the Feds then you are busted. It is argued that there is plausible deniability, because it is possible that your node was not downloading the file because you asked for it, but simply forwarding it for somebody else. Given the state of the judicial process at the moment, I'm not terribly optimistic about this defense.

      Freenet also doesn't protect (at least not very well) against traffic and timing analysis, allowing one to track down the author of something using the timing and amount of encrypted traffic that nodes exchange. I don't know of any case of traffic analysis having been used (except maybe on the NSA hyper-spook level), but it isn't impossible.

      Another thing that Freenet does not "anonymise", and this is the most important IMO, is that you are running a node in the first place. Your Freenet node has to be public, so the feds could definitely "fish" the network for node addresses and start busting those who run them. Again there is an argument of deniability: you don't actually know what is in your nodes cache because it is encrypted, but again I don't have a lot of faith in this defense when the prosecutor will argue that you knowning acted in bad faith.

      Regarding Winny, however, I think I agree with Ian. It seems doubtful that Winny works in the same manner as freenet, for the simple reason that Winny works, and well, freenet, umm, doesn't. Any time you try to put anonymity into something, useability IS going to take a hit, because trying to spread and bounce traffic necessarily hits performance. I have a very hard time believing that Japans most popular P2P network could be based on tunneling everything - purely for performance reasons.

      (I have to run, so forgive typos and pitiful spelling errors.)

    Since Winny is pretty much unknown outside Japan, here is some background information for slashdot readers: Winny is a P2P file sharing program created by a Japanese programmer, who still remains anonymous to this day. It came out two years ago as an attempt to share copyright-protected materials "safely" when somebody was arrested for using another P2P program (WinMX). Since the application was extremely well designed and almost anything is available on its network, from movies to software, it has become immensely popular in Japan, so much so that there are a dozen book available on how to use it and network traffic in the country was down 20% after the news of the arrest broke. As for the reasons why the police was able to identify those two people who were arrested, they used an extra bulletin board feature, which does not guarantee anonymity unlike its file transfer feature, to distribute a list of warez videos. Therefore, I don't think this news has anything to do with the validity of Freenet's technology, or with that of Winny's for that matter.

      Mod parent up. This discussion can't go anywhere without the participants having proper knowledge of the background and workings of Winny.

      The reason that nobody's heard of Winny is that Winny has been deliberately kept off the radar of countries outside Japan by the author himself. He keept the source closed and only provided the program and documentation in Japanese.

      Winny is "based" on Freenet only to the extent that the creator of it consulted Ian Clarke's papers to design the network. The possibility of Freenet code being reused in Winny is pretty low, as Winny is a native Windows application and there's that issue with GPL code anyway.

      The architecture of Winny has some aspects in common with Freenet, but while Freenet was designed with anonymity as priority one and usability as backburner, Winny aimed to become both a usable AND anonymous P2P client. To achieve this goal, some of Freenet's anonymity features (such as the inability to know the data inside one's own node) was removed from the design of Winny, and some usability features such as searching within the program were implemented. Winny's design is not as modular or portable as Freenet is, either; Winny is a native Windows application tied to a GUI, more like "normal" P2P filesharing apps.

      Winny version 2 also includes an anonymous message board system, a bit like Frost's TOF; Due to the original Winny's immense popularity, The Winny message board became a lively place of discussion, also often used to request and announce up/download of illegal files.

      Presumably, it was this that the Japanese police used. Due to the way Winny implements the anonymous message board, reading and posting in the threads are anonymous, but creating a new thread is not. Both of the two people arrested were thread creators, and they announced the upload of files in their threads. As this was not anonymous, the police probably traced them using this.

      Any additions/corrections from Japanese Winny users are welcome

A single server does not contain everything needed to recreate the file, nor do you necessarily know on which servers the file fragments are stored ahead of time. If you are the server owner, you cannot determine what's in the file fragments you carry, nor can you reconstruct the files without knowing the correct key, which Freenet will use to gather fragments from all over the network.

      And, I'm told, most people can escape imprisonment or heavy fining by just apologising well.

      I'm not saying this guy is innocent, but he got a longer prison sentence than most murderers. Japan has a conviction rate above %90 percent. They can also hold someone on suspicion for up to 21 days without so much as a phone call. My greatest fear is just being a suspect. It doesn't matter if you're guilty or not here. So I get a heavy fine and no "prison sentence." I could still be in prison for almost a month before charges are even filed.
      • What I said was purely based on what I've been told by people I trust (heresay nontheless). I don't know anyone who has actually had to go to court here.

        But yeah, unless you're a foreigner, you can get off easily.

        That goes without saying really.

        Actually, if he'd just "confessed" and apologised profusely, he still might have got a more lenient sentence. Maybe get out in a couple of years.

        In any case, its an unfortunate incident, I'm going to forward it to people I know here in Japan. I don't think the lo

      You're saying listening to Hanson wouldn't drive someone to kill themselves *first*? Mind you, going by some of the J-Pop acts, maybe the Japanese have a higher tolerance.

  • Winny is more advanced than Freenet (Score:5, Interesting)

    Winny was developped by the Japanese developper called "47", and it was after WinMX user was arrested here in Japan, in 2001. It was the world-first arrest of P2P users. Japanese copyright law was amended in the years before to crack down infringement over internet, protecting "right of enabling sending copyrighted material".
    Since then, among Japanese users and hackers, non-encrypted P2P which is still popular in the West today became things of past.

    Since Freenet made of Java was very slow application then (not much improved today), he made Winny as native Windows P2P application, with encrypted storage distrubited across peers. According to the developper, Winny is good at the both anonymity and efficiency, but anonymity is slightly lower than Freenet. Because a receiver can't determine a sender is the one who originally inserted the file to the network or not, it was considered anonymous and then more secure than ordinary P2P network, say, Gnutella or eDonkey etc. Winny has other functions like forum system, and clustering by keywords combination set by its users which help users with similar interest mold cluster. Other remarkable difference from Freenet is it dosn't split files, but can do multiple-source download.

    With the help of community and its own efficiency as P2P network, Winny become extremely populor in Japan unlike experimental Freenet in the West and consumed huge bandwidth.

    But those who were arrested the last month was arrested because they sent files directly, without being a bridge, or put some warez onto web page and running Winny beside it. Therefore it is still not clear whether just running Winny and sending cached files without modest deliberation means guilty or not.

    The way annoymity works is that files are stored in a "cache" in a scrambled format with filename concealed, even to the local user.

    Winny knows how to descramble the name and data, and it can search on the P2P network a specific file using its filename or MD5 checksum.

    When a file is found, it is either downloaded directly or through another random user (think proxy).

    Files goes into the cache either by local upload, by downloading a file (which Winny will descramble for you, leaving a copy in the cache), or by files passing through your node. It is then available for further download by other people.

    This provides a kind of load-sharing where more popular a file is, it will be found in more people's cache and more easily available. Downloading from multiple sources is also possible.

    You can find out who your immediate neighbour is, but he can claim he doesn't know what the content of his cache contains an infringing file, but of course this requires him to remove the original on his disk :)

    To give an incentive to people to cache files, # of simultanenous downloads is limited to # of uploads+1 with a lower limit of 2.

    It is a very convinent system because winny has a function that let you specifies search parameters and you can just leave it alone and it'll download everything that meets the parameters, meanwhile donating bandwidth and cache space to other people on the P2P network.

    This model can be possible only because Winny is closed source. Cracks have both appeared for both the download limit and cache descrambling. It is easy to see widespread use of the cracks will compromise the model (less files to be found on the network).

    Fortunately normally people don't care (it is just spare upload bandwidth and disk space, which broadband P2P users usually have surplus of).
  • Just found a link to The Motley Fool [fool.com] that very much suggests that file-sharing isn't taking any revenue. If this is truly the case, how do they justify the restraint of freedom [slashdot.org] induced by laws and methods of enforcement? This appears to be less a case of protecting revenues as a simple imposition of unjustified power.

  • I believe that the words "arrested for downloading..." should not be appearing in our lives because "arrested for downloading music" sounds very similar to "arrested for downloading political material" and this is exactly how a society moves from free to big-brother. Lets put things in perspective here: You are not gaining unauthorized entry to a remote system, you are not 'stealing' (as in bank notes) money, you are not diverting electronic funds to yourself. Flaim me all you want about what you 'are' doin

    • "Its society's job as a whole to decide the balance here, personally i think filesharing should be accepted and that it will lead to a positive change in the way things are done and the way music is made."

      The problem here is that giving rights to one group (those who desire to have copyrighted material without requiring permission from the rightsholder) means taking rights away from another group (artists, poets, composers, writers, or anybody who would like to have a say in who can "share" their work).

      • I don't have a position on this issue yet. I'm as confused on this as anyone (even though I usually have opinions on nearly everything). The difficulty in arriving at a stance is described by your post. However, I do disagree wtih some of your points.
