A File Protection Scheme based on the Transparent Encryption Technology

File system is the most important resource in computer system, and encryption is a good method to protect them. At present, the majority encrypt methods are implemented on user mode using keys, but unfortunately the effect is not very well. On the basis of analyzing the data leakage mode, this paper proposes a file protection scheme based on the transparent encryption technology. The transparent encryption technology is a technology combining with Windows, which works on the bottom of Windows. This scheme is based on kernel driver and through the way of custom working software. It provides a flexible and more secure operating environment for users and protects the security of important data within the enterprise.
