Napster, Audio Fingerprinting, and the Future of P2P 141

Posted by CmdrTaco from the well-I'll-believe-it-when-I-see-it dept.
mjmalone writes "Napster founder Sean Fanning is poised for a comeback, seems the now 22 year old Fanning has developed technology which creates "audio fingerprinting" of individual tracks and compares them against fingerprints in his firm's database to determine legality. A fee may be set and collected on a copyrighted track by its rightful owner. Fanning is actively recruiting industry support as well as pushing the idea to p2p services such as kazaa and grokster. " This isn't exactly new technology, but it's still interesting to see what Fanning is up to these days besides movie cameos.

      Umm no.

      This is not going to make P2P "legit".

      This is going to further destroy legit and non infringing usage of P2P. Now, RIAA will still say "p2p has no purpose other than piracy ban it"! And if people start paying for music from these services, guess what LEGITIMATE users of p2p suffer.

      Sean Fanning did not invent P2P. Before napster we used to have IRC/DCC bots etc. and web search pages. Sean Fanning made downloading mp3's easier for the masses because of his windows client that automagically shared files you had downloaded. He's great but he's no God.
      • Sean Fanning did not invent P2P.

        I'm sure lots of people around here already know this, but Sean Fanning's service wasn't even P2P, it used a client-server model, which turned out to be its achilles heel. Killing a service based on that model is a simple matter of removing the servers, the vast majority of which were owned by Napster. Thats why P2P has become the prefered method for trading, it suffers from no such weakness; all nodes have to be individually removed.
        • Not prefered by everyone. P2P relies on peers, which in this case means the general population. People on average have low standards, thus P2P is great for everyone else with low standards. For anyone that actually cares about quality, FTPs used to transfer group releases are still the prefered method.

          Works much better than P2Ps also.

        This is not an md5, this is spectral analysis "fingerprint" of the song. Thus they can identify the song no matter what the encoding (within reason, of course, but you wouldn't want to listen to a song so badly encoded that it can no longer be recognized anyway).

        See http://musicbrainz.org/ for some software that uses the same technology to help you tag your MP3s.

          PGP

          Yeah, there are issues re: p2p, but the tech is there.

          Also there's Freenet Project which obfusicates the source. You can ID it, but you can't get rid of it.
          • I was trying to come up with a way to essentially obfuscate the mp3, while still leaving it as a valid mp3. Rearranging the frames (even just swapping every other frame) could yield a valid, although scrambled, mp3.

            You could use PGP to encrypt the mp3, sure, but whose key will you use? It would also no longer be an MP3, even if you stuck an mp3 header on the front.

            Freenet is interesting, but I have no compelling reasons to use it myself. Same with the new napster.
            • I haven't RTFA, but I'm assuming this fingerprinting would analyze the analog signature, not the digital one. If this is true, then any publicly playable format would be ID'able even if the digital format were obfuscated (damn I spelled that wrong in my earlier post). If you can hear it, you could ID it.

              If you want to avoid being ID'ed, I think you would have to hide one of three things:
              • The source
              • The content
              • The distribution method

              Most P2P relies on all three bits of info being readily available. Free

              • Just an aside about the last part of your post. I'm not entirely sure what crypto scheme and such Freenet uses, but sometimes the algorithm, if known, can be used to determine that 2 keys were made on the same machine, or by the same user, but it would only be about as reliable as a woman finding a short brown hair on her husband's shirt and assume it belonged to their young child with short, brown hair. And I'm not talking about comparing the hair's DNA either.
        • OK, I propose the 3PM format: The header is the same as an MP3 file. The ID3 tag is the same as an MP3 file. The audio data is byte-swapped, so the four bytes ABCD are stored DCBA. If the length of the audio data is not a multiple of four bytes, the last 1-3 bytes are left untouched. The extension can be .mp3 or .3pm, depending on how easy you want to make it for Sean to filter out byte-swapped files.

    the cat's already out of the bag. The real issue here is the existence of the middleman in the music industry. Prices of CDs are artificially inflated by the middleman (the music outfits behind the RIAA), because they control most of the musical output in this country. Consumers want this music, and some continue to purchase at these inflated prices. But when you can get the same music, albeit illegal, from an alternate provider (KaZaA et al.), why bother paying those prices at all?

    The solution is to bring the price of music back down to a reasonable level. If consumers are able to more directly compensate the artist for their music, and they can do so at a more granular level (i.e purchase tracks, vs CDs), and the easy of use is comparable to the p2p networks, then I bet you'll see a rebound in purchases. Granted, not all the people who use p2p will buy legit copies -- but I bet you'll see a significant rebound.

    This country is long overdue for some overhauls on copyright / fair use law. The RIAA likens consumers who use p2p as criminals, but the RIAA backers have already been convicted for price fixing and routinely screw the artists they purport to represent out of cash. Criminals calling their target market criminals? Even if they're right, it's a matter of the pot calling the kettle black.

Exactly how it turns out is anybody's guess, but consumers are on to the RIAA's schemes and have a found a way to get their music without their shenanigans.

    The concept of audio "fingerprinting" is an interesting one, but likely outside of Fanning (and his local folks) experience or abilities. Fingerprinting has to rely on one of two things. The first is the artificialities of files -- things like file length, name, checksums, etc etc. All of these are easily overcome, and likely not robust to differing compression/bit rates/etc. The second thing it could reply on is data content -- that is, things like how many beats per minute, the time/frequency pattern in segment(s) X, Y, etc etc. I'll call this analysis of content. Unfortunately, simple analysis of content and watermarking schemes are very easily detected and overcome (remember the Felten/audio protection challenge?). TRUE analysis of content (when certain instruments play, their timing, the singing, etc) is a very difficult signal processing problem that won't be overcome without serious mathematics.

    If you use audio fingerprint scores in the aggregate, for example to see what's popular, it works. If you depend on any one audio fingerprint matchup being accurate, especially accurate enough to use for legal notices, it doesn't make sense.

    Music is a semantic object. Saying whether two pieces of music are the same thing depends on stuf
    • Audio fingerprinting could work for the publishers in a way not unlike BMI/ASCAP handles radio royalties. In Fanning's scheme the users could pay by volume (DL'd 100 @ $.85 + 150 @ $.00 = $85) while the royalties are paid out like radio. Hmmm.

      Again, good for free music. Plus pays copyright holders. I am all for it. Especially if the Windows masses get a simple, spyware free P2P client out of the deal.

Those intelligent enough to understand that their favourite artist needs cash to survive will pay whatever they deem appropriate or a reasonnable fixed price.

And even if you wanted to enforce copyright laws, you can't prove that the targetted ip/account hasn't been hijacked/trojaned and/or it was a specific person behind the computer.

  • Perhaps we can take the time to look at the root causes of the whole P2P/ music industry / RIAA debacle. We all know the context. But what are the hidden assumptions? Can we reanalyse these? And can we find a new model for buying and selling digital media that does not pit the greedy tycoons against the valiant hackers? I think so...

    1. The first assumption is that consumption is completely elastic. In other words, people will pay whatever the goods they want cost. (Assumption of the media industry.)

    2. The second is that value is constant. In other words, digital theft by a million people is equal to physical theft of a million CDs.(Assumption of the media industry, who come up with bizarre figures as to the "loss" sustained thanks to illegal file sharing.)

    3. The third is that digital content has no value. In other words, digital theft is not theft because bits and bytes have no value. (Assumption of the file swappers.)

    All these assumptions are wrong.

    First, consumption is almost completely inelastic. People will spend every disposable penny they have. If goods are cheaper, they will buy more of them. Raising the price of goods simply decreases demand.

    Secondly, value is not just constant, it is almost always inversely proportional to rarity. In other words, the more of an item is available, the less it is worth.

    Thirdly, of course digital content has value: that people go to great lengths to aquire it demonstrates this. However, its value is subject to the law of rarity.

    What does this all mean?

    Firstly, whether or not people illegally share music (and the same applies to movies), the value of media is going down inexorably thanks to the huge volume produced. And I'm not speaking of the cost of manufacture, but the perceived value, the price people are willing to pay. Diamonds cost practically nothing to produce, their value comes from their rarity.

    Secondly, an industry faced with this value equation has several options. They can try to restrict supply and eliminate competition, which is what the music industry has done for about 20 years since the CD eliminated the production bottleneck. In a competitive market they will lower their prices so that consumers stay loyal. We have also seen this. Finally, they can ignore reality and die.

    Thirdly, one of the ironies about digital distribution is that it eliminates the rarity variable. This means that any object distributed digitally will inevitably tend towards zero. I can download music from the Net but I value my own (irreplacable) CD collection much more.

    I believe that even the 'pay as you go' model is doomed to failure. The only sustainable model is one in which prices are set by the market and production by the producers.

    So, what I propose (or rather, predict, for this is almost inevitable) is a media market that works as follows:

    1. The producer of a work creates a specific number of instances of the work. This can be as large or small as they want, but they cannot change the quantity afterwards.

    2. The instances are individually serialized so as to be traceable to their owner. They can be copied freely.

    3. These instances are now auctioned and can be resold in an open market.

    This scheme can be applied to music, writing, photographs, almost any digital creation. Imagine a famous writer produces a short story. They issue a series of 1000. Now, you can buy one of these copies. It will be, forever, an original that is certified and unlosable. The price is set by auction, and the rights to these copies can be traded in an open market. What's the cost of a 2003 Madonna? Around $1.20, these days. And a 1998 Leftfield? Up to $30, if you can get them. In fact, you have paid not for a real thing, but for a slice of rarity. Sound strange? What about shares and options...?

    There is only one requirement for such a market, and that is the market place. All the rest follows from the natural laws of supply and demand.

    • Diamonds cost practically nothing to produce, their value comes from their rarity.

      Interesting comparison. Do some reading about DeBeers. They pretty much restrict diamond supply worldwide to keep the prices up. The music industry is trying to pull off the same thing, but it's much harder to restrict bytes than rocks.

      For some reason, demand for real diamonds is high, too. Science is now able to create diamonds that are molecularly nearly identical to natural diamonds. I asked a lady friend if she would ca
    • Your suggestion is very interesting, but it relies on the assumption that people will not be prepared to buy counterfeit copies. In the digital realm where copies are perfect, I'm not sure that's a realistic assumption.

      Of course people might not be willing to openly sell counterfeit copies if there's an audit trail, but it will be possible for resellers to "fork" a legitimate artifact by selling multiple copies, each of which appear to be legitimate because it will have an audit trail leading back to the

    About these 'fingerprints' - are they SIMILAR for similar pieces of music? Or are they only useful for identifying the one piece of music that each fingerprint is for?

    If the 'fingerprints' are similar enough, you could ALSO use the technique to search for songs that you may have never heard but match the general style of music that you like. Sounds like something independent musicians could really benefit from ("Hey, I'd never heard of THESE guys before, but their music is exactly the style that I like....")

    And if this is NOT the case, is anyone working on a "music style" analysis of some sort that could be stored in a 'searchable' fashion? (i.e. take your favorite song, run it through an analysis program to get it's 'fingerprint', then feed that 'fingerprint' to a search engine to get a listing of similar songs...)

    As a class project, a friend and I built a music recognition database. You can read our paper [trevorstone.org].

    The general approach is fairly straightforward. You extract a set of "features" (typically several Mel Frequency Cepstral Coefficients, or MFCCs) from each sample of the song, say 10ms. You then pick several (say, 16) arbitrary points and iteratively generate that many "average" feature vectors, along with their weights so that they all sum to a one vector. This data is turned into a Hidden Markov Model (HMM). To see what audio you have, you run it through each of the possible HMMs and see which produces the greatest likelihood.

    This method is typically applied to speaker recognition, where a linear search through HMMs is reasonable. This obviously isn't the case when you know about hundreds of thousands of songs, so a large part of the challenge is narrowing the field of HMMs to check (which is one of the focuses in our paper). Relatable [relatable.com], who were working with Napster a long time ago, have clusters that can classify 1,000 songs per second; I'm pretty sure they use this technique.

    This technique has several important features. First, it doesn't depend on any properties of files themselves. Checksums would be trivial to beat, looking at a file's length could be circumvented by inserting silence, etc. Since this creates an average of sample data, a song would need to be changed quite a bit to fail to match. (The system is robust to, for instance, changes in bitrate, slowing the music down, and rearranging bits of the song or putting it in reverse.) We didn't have enough "derivative" music to test how it handles sampled music vs. the original -- it depends how much is changed.

    Finally, this sort of system is useful for much more than song identification. You can build a model for an artist or genre and determine how to classify the song. One of my focuses in the paper is unsupervised genre classification -- my tests indicated some fairly reasonable groupings. This technique could be used for music recommendation -- "You like Dropkick Murphys? Well, they sound like Flogging Molly, so you might want to check them out."
    • George Tzanatakis has an open source framework for audio analysis [sourceforge.net]. Amongst the things his framework does is accurate automatic genre detection, mfcc, fft and beat detection.

      He also developed the fingerprinting for moodlogic which works.

      Philips also have a paper describing a system for fingerprinting, they can detect a song based on any 5 second sample.
