Watermarking through word swapping

FYI 


In http://paidcontent.org/2013/06/14/new-ebook-drm-will-change-the-text-of-a-story-to-prevent-piracy/

> Germany’s Fraunhofer Institute is working on a new ebook DRM dubbed SiDiM that would prevent piracy by changing the actual text of a story, swapping out words to make individualized copies that could be tracked by the original owner of the ebook.

[…]

> But here’s the twist: German blog Lesen.net pointed out that the book publishers actually joined because they’re interested in finding alternatives to the traditional lock-down approach of DRM, simply because they’ve learned in the past that even the strongest lock can be broken.
