I have written about this on
my forum under the heading: "eBooks and eMagazines."
You have to sign up, because of reasons I don't like to repeat for the n-th time at WPW.

You think of systems like PayLoadz?

Am I right? Or is there a secure way to sell ebooks?

Screen shots should be possible to handle by locking the relevant keys on the keyboard. OCR scanning is more difficult, but it requires advanced filtering and programming.
One very simple solution:
Kjell Bleivik, CV and some poems etc. in Norwegian only
Click on "Hele diktsamlingen" in the left menu. It should be possible to give a random password that can only be used n-times even if the PDF file is downloaded to the disk. I have Adobe Professional 7 and do not know what is possible in version 8.
You can price the book depending on how many times you are allowed to open the document.
I indicate more advanced solutions in the above forum post.
