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 dot matrix file of the text to be enciphered from the memory unit, each dot matrix in the dot matrix file corresponding a sign pattern (character symbol or non-character symbol), each pixel dot corresponding a display attribute and a brightness value, an encryption position determination module for determining encryption position according to preset position parameters, a decision module for deciding symbol pattern of the dot matrix and display attribute of the pixel dot on the encryption position, an encryption module for adjusting brightness value of the pixel dots on the encryption position, and a storage module for storing the enciphered text information to the memory unit. The system can be used to adjust the brightness value of the pixel dot corresponding the characters in the text, thus realizing 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.
