PDF Viewer Add-on

Hello, i m interested to buy this add-on, but i need to prevent members from downloading, printing or other way to get the document, also to hide the source code in some way, in short to make it impossible to get the original document else it is notr feasible to alow them to download like it is set at the moment with WPDM plugin.
I will allow only to view, search, copy text and zoom, also a hand to drag would be useful.
Thank you.
