Does anyone know how I can hinder or potentially stop someone from sharing my ebook over the internet after I post it on my landing page and they pay for it? I was thinking maybe I could embed it in the site and offer a login/password to use the book. Then maybe I could make the login only accessible from 1 ip address. How can I prevent piracy of my ebook if I am the only one selling it on my site? Note: I have no site or ebook yet.
