Abstract

A control method of a recoverable file protection device and a protection method of a recoverable file are provided. After a file owner sets a secured content in an unprotected data, a secured content protection mode is selected. In accordance with the secured protection mode, the recoverable file protection device can move the secured content and the marked content can replace the secured content. An authentication key is inputted to encrypt the secured content. If a user would like to open the file, the user is requested to verify an identification data. If the identification data complies with the authentication key, the recoverable file protection device moves the secured content to recover the original content. If the identification data doesn'"'"'t comply with the authentication key, the file content without the secured content is opened. Therefore, a security of an e-file can be achieved.
