BooXtream does away with costly and cumbersome DRM encryption used by major publishers, and it replaces that encryption with a more subtle DRM that embeds information about the buyer of an ebook. That information could include email, name, the eBookstore where the eBook was bought, as well as a digital watermark.
The developers of BooXtream believe that DRM doesn’t actually stop piracy; all it does is irritate customers. Given how easy it is to find DRM removal tools or pirated content, they are very likely correct.
One Dutch publisher has already signed on to use BooXtream, Bertram + de Leeuw.
