Hi Just wanting some quotes on this project? I want a script similar to that of http://www.locklizard.com/pdf_security.htm?gclid=CMuTuP-4kJYCFQUvlAod5B7qEg which should enable content writers such as businesses to track, disable and enable use of their PDF content. It should be very simple and provide a secure solution. It must be compatible with both macs and windows, and there must be no extra software required to view the pdf. The pdf authour should be able to manage the pdf from their user account on our site, which is simple and allows them to see who has viewed their document, disable viewings apart from certain people and make it so that people have to activate it to be able to view it, the user will still be able to disable it later. Thanks
