Another idea is to prevent the reader from ever downloading your PDF. A single PDF can always be downloaded. So, burst your document into individual PDF pages and then wrap them in our HTML skins. When you burst the PDF, supply additional security settings for the output pages so that the reader won't be able to easily reassemble them. Make sure you installed pdftk first. For example:
pdftk doc.pdf burst encrypt_128bits owner_pw 23@#5dfa allow DegradedPrinting
After integrating your document into your web site, you can employ user accounts, passwords, and other common security devices for enforcing access permissions.
Skinned PDFs are vulnerable to being copied from your site using a recursive HTTP robot. The result would be an exact copy of your site's pages (PDF and HTML) on the user's local machine.
