Abstract:
     Disclosed is a text encryption system and method, wherein the system includes a memory unit for storing text information, a text acquisition module for acquiring pixel dot file of the text background to be enciphered from the memory unit, each pixel dot in the file corresponding to a brightness value, the background including rough background and smooth background, an encryption position determining module for determining pixel dots in the rough background, an encryption module for adjusting brightness value of the pixel dots in the rough background corresponding the encryption position, and a storage module for storing the enciphered text information to the memory unit. The system can be used to realize explicit encryption for the text, wherein the encryption information of the text can be indicated explicitly during the display procedure in the mode of paper document, the owner of the copyright can be identified and copyright protection can be implemented.
