      Secure PDF Files

      Secure PDF files include digital rights management (DRM) software. DRM is included at the request of the publisher, as it helps them protect their copyright by restricting file sharing. In order to read a Secure PDF, you will need to install the FileOpen Plug-In on your computer. The FileOpen Plug-In works with Adobe Reader and other viewers. Visit FileOpen to see the full list.
