Text encryption system and method

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.

Description

【Technical field】 [0001] The present invention relates to an encryption system and method, in particular to a text encryption system and method. 【Background technique】 [0002] With the advent of the digital age, the digitization of information has become an inevitable trend. However, due to the dissemination and easy copying of digital information (such as: text, pictures, images...) and the vigorous development of the Internet, people can It is easy to obtain information from the Internet, so the protection of digital information is no longer as easy as that of traditional copyrights. Therefore, the protection of digital information copyright and related intellectual property rights have attracted much attention and become urgent issues that need to be resolved. [0003] The most widely used at present is "watermark coding technology". The so-called "watermark coding technology" is to embed some watermark information irrelevant to the original digital information in the o...

Problems solved by technology

However, judging from the currently known "watermarking coding technology", these so-called watermarking technologies that can achieve a considerable degree of toughness can only have a certain protective effect when interested parties obtain digital information in the form of digital processing; However, when interested parties obtain information in the form of paper files by taking photos, printing, etc., they cannot confirm the information in the form of paper files through restoration operations, that is, they lose the role of copyright protection.
