A data protection system and method apply to a computer device. The computer device links to a data protection system. The data protection system contains or links to at least two storage units. The data protection method partitions all the storage units into two blocks, and one block functions as an active memory zone, and another block functions as a backup memory zone. In each cycle of data backup, a portion of the operating storage units are backuped to the storage units in the backup memory zone. Then, the role of the storage units that have been backuped and the role of the storage units that have backuped data interchange with the active memory zone and the backup memory zone respectively having original numbers of the storage units. When one storage unit malfunctions, data can be retrieved from another storage unit and written back to the malfunctioning storage unit. In the present invention, the storage units alternately backup data. Thereby, the storage units are averagely used, and the service lives thereof are prolonged, and data intactness is guaranteed. In the present invention, a mirror-technology is used to backup data and maintain the correctness and security of data. Therefore, the present invention can provide an effective data protection method.

A system and method for encrypting an electronic file in a mobile electronic device reads bytes of the electronic file from a cache of a memory system and divides the bytes into a plurality of byte lines. The system and method further assigns a numerical cipher to each byte line and searches a position of each numerical cipher in a corresponding byte line. Furthermore, the system and method encrypt each byte line by inserting one or more random bytes into each byte line, and generates an encrypted electronic file by combining all the encrypted byte lines.

A control unit 112 of an image forming apparatus generates a first image pattern in which a user information authenticated by an authentication processing unit 113 and an application information concerned with a predetermined application that can be used in the image forming apparatus by the user authenticated are embedded, and displays the first image pattern on a display unit 105.
