Correct me if I missed something, but wouldn't it almost have to be something similar to an MD5 Sum of an entire book. Even if they only store the differences from the original, all the variations sold on all available titles sounds like it could get a bit ... unwieldy (or did I mean not wieldable?). |
Maybe a "phone home with the difference"? The real reason it won't be effective for a serious pirate is that you still have the original DRM'ed text to compare to. Plus you'll be De-DRMing the randomizing algorithm. There are such things as hex editors...
But publishers were never known for their smarts...
(You don't want to do an A - B compare. you want at least three (and better 5 or 6) decrypts for the compare. You keep the text that shows up on the most of the version (at least 2). If there are words not common in all of them, flag it and tell the user to go look at the original DRM'ed version and correct the De-DRM'ed copy.)
