You can check Nate Hoffelder's The Digital Reader columns for more information starting with Researchers Reveal Booxtream’s Digital Watermark DRM and the booxtream.txt file linked there. Google will help finding more information if you are interested in further research.
I will admit to purchasing the entire set but it was for my daughter -- anything that encourages kids to read is a Good Idea IMNSHO. |
I have no issues with watermarks. My only concern is being able to read the book anytime I want in the future, even if the DRM authentication server goes away, and watermarks let me do that.
