What you are describing already exists and it’s, per example the DRM used in the eReader, and one of the principal reasons that as made it a very popular format.


In Microsoft Reader DRM lingo, it’s the level 3 of DRM:

“Inscribed eBooks
Inscribed content displays information from the purchaser (for example, the name of the purchaser) on the cover page. This reinforces honest usage by consumers.”

Still Microsoft Reader and “similar” formats - ex: Mobipocket - uses the level 5 of DRM:

“Owner Exclusive eBooks
Publishers provide these eBooks with inscribed security plus an additional encrypted license that requires you to activate your computer for Microsoft Reader before purchasing and reading these eBooks. Publishers prohibit you from copying and pasting text from Owner Exclusive eBooks into other applications. They also prohibit you from using the Text-to-Speech functionality.”
