Disclosed is a system that enables monitoring and/or control of user file access in a PC or a mobile system by inserting a physical key of a USB device or a PC card that carries security policies copied from a central site for the user. The system can distribute a set of centrally defined security policies, enforce the policies, create file access logs, and embed water marking in the target files, all by using the physical key devices, safely without the need of all-time connected communication network.
