Amazon Kindle Proprietary Format Broken

Posted by kdawson on from the let-a-thousand-e-books-bloom dept.

An anonymous reader writes "The Register reports that the proprietary document format used by the Amazon online store and Amazon's Kindle has been successfully reverse engineered, allowing these DRM-protected documents to be converted into the open MOBI format. Users of alternative e-book readers rejoice." Here are the hacker's notes on the program he is calling "Unswindle," and here is the (translated) forum where the Kindle challenge was posed and answered.

    There have been a set of python scripts around for more than a year and a half that allow you decrypt Kindle files to mobi. The challenge has always been in dealing with Topaz files and, unless I am missing something, they still haven't been cracked.

      This removes the drm from the books downloaded using the Kindle for PC app.

      As you mentioned, the scripts you linked to have been around for a while but only remove the drm from the actual kindle and kindle for iphone books.
      So, if you have an iphone or a kindle this doesn't really change much as you could already do it. This would be useful for anyone that is only able to get their books through the Kindle for PC app.

      the THEY you are referring to are the uninformed masses. THEY have the buying power and THEY generally trust the large corporations more than they trust the informed among us, because there is a mentality of "If I saw it on TV (or amazon.com for that matter) it MUST be more trustworthy than the neighbourhood geek"

      Sigh... we geeks really have to work on our marketing... we need an image consultant!

  2. Convert everything you have quick by Mr.+Freeman · · Score: 5, Insightful

    I'd suggest converting every book you own really fucking quick. No telling how long it will take Amazon to make a similar format that will take another year or so to break. You can bet that once they do, they'll remotely switch everyone's ebooks over to that new format and then push a firmware upgrade to ensure compliance.

    Wait, I've been using MobiDeDRM for a while with my Kindle's Mobi serial number to strip the DRM and leave me with Mobi files. How is this different, exactly?

    This gets the Mobi serial number from the Kindle For PC application. Now you don't need to own a Kindle or iPhone to buy Kindle books.

    If publishers were really thinking that, they were not really smart.

    DRM has two sides. The content producer, and the consumer. Both lose control to the DRM provider. Look at iTunes and the ITMS. Apple got a virtual monopoly on digital music players, so any music publisher wanting DRM and sell music online and wanting to have an audience larger than 10 would have to go to Apple. Apple knew that. It gave them a lot of pricing power and control.

    Now the music publishers realised that, and have started to sell non-DRM music, so they can at least dictate the terms again. There is competition between the stores: they all want to sell music.

    At the moment ebooks go the same way. Amazon is a giant, their Kindle is very popular. If a publisher wants to sell DRMed books, they have to go the Amazon/Kindle route. Great for Amazon: they have a double monopoly (readers and content). Not good for authors and publishers. Amazon can demand a greater profit on sales than in an open market, and if Amazon doesn't like your title too bad. You can not go for another DRM as the most common reader can not read it.

    I have argued the same before, and will continue to do: DRM goes away because it gives all control to the DRM provider. And the content provider (music labels, publishers, authors, movie studios, TV channels, etc) have to sing to their tune. On top of that it fragments the market: imagine, you are an author, you want to publish your book, and not knowing much about digital technology and distribution you want to "protect it against copying because otherwise everyone will steal my work" so you want to add that cool DRM technology. Then you have a choice of distributors: you could go with DRM1 and you get 40% market share, as their DRM1Reader has a 40% share of e-book readers. Or you could go with DRM2 and you get 30%. DRM3 and DRM4 each have 15% market share. And neither allows you to license to anyone else, so you can not reach more than 40% of the market.

    Of course everyone will go to the DRM1 company to grab the largest distribution potential for their work, which then grows and grows and grows to say 80% of the market. And has full control over everything: distribution, pricing, commission for themselves, whether or not to promote/feature your work, etc.

    That is what happened to Apple's iTunes. And that is the real reason why everyone is now selling DRM free music. Not because consumers do not like it because in this game no-one cares about the consumer as long as they consume. But the content owners lose control over their content, and lose sales.
