Abstract: A method and system for file content protection and policy-based access control in a networked environment are provided. It includes an endpoint module which runs on endpoint devices and a key store module which runs on key stores servers. The endpoint computing device where files are created and used generates a content encryption key and unique file identifier (UFI), which are different for each file.
