A Traceable File Protection System with Transparent Encryption Technology

As sensitive data in personal computers are facing more and more security threats, we design a traceable file protection system with transparent encryption technology in this paper. It combines prevention with diagnosis of data leakage and achieves multi-level protection of data. The system has attributes as follows: Firstly, it does dynamic encryption or decryption for sensitive data at driver level and the operators needn´t get involved in. Secondly, the system can be used in LAN sharing and it ensures the safety of data which is transmitted from one operator to another. At last, the system can automatically record the user´s computer information and store them in the file which is operated. If the file was leaked, we can trace the transmission path and find who leaked it according to the information recorded before. More importantly, this novel system has been tested in real network and the results show the efficiency and convenience of our design.
