Researchers Create New Copyright Protection That Changes Words In Your E-Book
"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." Wired 06/17/13
