[Plugin] PDF Viewer WordPress Plugin that can track viewer info

I am working on an Intranet WordPress setup right now.My client wanted a simple way to view documents(like PDF,XLS,DOC, and etc). And those documents are confidential only the employees can view and cannot be downloaded and brought outside the company premises. So I would like to know if there are existing PDF Viewer Plugins that work on intranet( I already tried Google Docs embed and other embed pdf plugins, but it didn’t work. ) and can track( like viewer IP Address, date & time viewed, browser used and other important details about the viewer), and also CANNOT BE DOWNLOADED the file while viewing.

Any suggestions or alternative solutions is much appreciated.

thanks!
