New ebook DRM Will Change the Text of a Story to Prevent Piracy
German researchers are working on a new DRM system that would change
individual words of a story to track pirated book copies back to their
original owners.
"The idea behind SiDiM is similar to the way rights holders have been
trying to protect music and video for some time. Instead of trying to
lock down copies through technical measures that prevent copying,
so-called fingerprinting measures simply add markers to a work that make
it possible to identify the original purchaser. In theory, this
prevents people from sharing their works for the fear of being caught."
