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. The file is encrypted with the content key and attaches the UFI to the encrypted file to create a protected file. The coupled UFI and content key are sent to the key store servers to be stored. To accesses the protected file, end point module reads the UFI and sends it to the key store which responses with the permission as the outcome of evaluation of associated policies and the content key if permission is granted so the file can be decrypted.
