As data leakage moves to ever more challenging areas, improving the security level of anti-data leakage and lowering overhead to the operating system becomes increasingly important. Therefore, the paper presents a novel double cache file filter driver based on transparent encryption, called as DBFD. In order to boost security of data, that is controlled by the file filter driver. The DBFD overcomes the limitation of double cache in the file system kernel in windows operating system and used the transparent encryption method to protect the data security.
