ebook security

[shurik]

Hi all,

This may be a bit of a challenge. I am to design a book that will be online based only. We don't want people to be able to share/distribute, print or save it - online reading only. But we also don't want just anyone having access to it, people need to buy it and only them reading it (I guess something like the ebooks you can buy and can't actually pass to someone else).

Has someone been dealing with such before? What suggestions / resources would you have? I thought about just making a .pdf that is secured, but then people can still forward it to each other. Not even sure if I've seen anything that works like that.

Thank you
