There is no DRM, in the sense of locking a book to a device. The file containing the book is encrypted, that's all. Only you can decrypt it, via your private key. Copy the file wherever you want, as many times as you want, and still only you can read it. Use any book reading program or device you want (they would all have to support public key encryption, and provide a way for you to enter your key - imagine this as a step in the software installation or device registration). Doesn't matter. The books are keyed to you.

If you're a skilled programmer with the ability to write an encryption/decryption program yourself, so that you can decrypt your books outside of a reader application, and then spread the plain text around, nothing in this system can stop you. Similarly, if you want to photocopy your Cybook screen as you turn each page... nothing will stop you. Nothing will stop dedicated pirates from pirating books.

Writing a public key encryption/decryption program isn't exactly trivial - so nothing in this system makes it "easy" to remove the DRM.

This system would even be stronger that today's typical DRM systems, because there would be no single universal "code cracker". A program to decrypt my books wouldn't work on your books.
