Project SIDIM: New protection measures for eBooks by individual text selections

It’s always a double-edged sword when one speaks of the protection of digital works. The acceptance of DRM in eBooks, for example, is quite low among consumers, they eventually restrict the disclosure in a small circle already massively. On the other hand, can be quickly swapped illegally Ebooks by their small file size naturally. A compromise between consumers and publishers would like to here the German research project SIDIM reach.

SIDIM Ebooks protection

SIDIM, an acronym for Secure documents by marking individual wants to protect eBooks and documents via a different route from the illegal distribution. Is less on preventing the actual copy in the foreground, but the distinct markings in the documents. This should largely remain to the ordinary reader “invisible”, but its undoubtedly traceable to a relevant offense, such as sheet describes the project .

Basis of consideration were digital watermarks, as they already exist in multimedia works. This watermarking based protection you will now also transfer new technologies to texts, they call it text watermark. The basic idea SIDIM shown by completely inconspicuous changes to the original text. A few examples of how this might look in practice, the researchers i n a survey of the authors queried.

Reading through the various texts it quickly, that does not change the content, but mainly small word changes, changes of arrangement of paragraphs or punctuation changes are made by the algorithm. If you look at the examples, it would be acceptable for me and preferable to the traditional paternalism by DRM. However, one must of course only once to test the algorithm in longer books, because a conversion rate could change the intended intention of the author in the worst case, and many readers are likely to want the original version of the author, rather than a modified version of an algorithm.

Whether you order the illegal exchange of books actually limiting because the one who is more traceable, one must also wait. The Federal Ministry of Education and Research provides in any case a future in it, and support the project by the Fraunhofer Institute. What do you think of this approach?
