Altering Text In eBooks To Track Pirates

wwphx writes "According to Wired, 'German researchers have created a new DRM feature that changes the text and punctuation of an e-book ever so slightly. Called SiDiM, which Google translates to 'secure documents by individual marking,' the changes are unique to each e-book sold. These alterations serve as a digital watermark that can be used to track books that have had any other DRM layers stripped out of them before being shared online. The researchers are hoping the new DRM feature will curb digital piracy by simply making consumers paranoid that they'll be caught if they share an e-book illicitly.' I seem to recall reading about this in Tom Clancy's Patriot Games, when Jack Ryan used this technique to identify someone who was leaking secret documents. It would be so very difficult for someone to write a little program that, when stripping the DRM, randomized a couple of pieces of punctuation to break the hash that the vendor is storing along with the sales record of the individual book."

    I catch all the typos in my books.

    They irritate me.

    I'd probably crack 'em, fix them all, and goddammit, that'd be "circumvention".

    Yes, which is why they have successfully stamped out piracy, it is part of the sordid past of the Internet. Thank god we'll never see pirated e-books again.

    Uh... yes. When you find misspelled words in my messages here, it's just my new DRM. It's just that. It's not that I'm too dumb to use a spellchecker.
