Embodiment Construction

[0021] The technical method is applied in the hierarchical management system for the application unit—China Shanghai Dongfang.com in the National Information Security Demonstration Project (S219). Its implementation flow chart is attached figure 1 .

[0022] As shown in the figure, the information issuer 15 includes a tag generation module 1 that accepts the original page content 7, and a hash algorithm module 2 that accepts the page content 8, and they respectively generate tag data 9 and hash data 10, which are sent together into character superposition The device 3 performs calculation processing to generate a superimposed character string 11, and then sends the superimposed character string 11 to the digital signature module to form a signature for the two data 9, 10, and the information issuing terminal 15 sends the data stream 12 to the information receiving terminal 16.

[0023] The aforementioned data stream 12 includes 1) original information content, ie original pag...

Abstract

The system comprises information transmitting and receiving ends. The transmitting end consists of a global greation module receiving primary page content and a Harsy algorithm module receiving primary page content which greate global data and harsy data, a character string superimposis receiving global data and Harsy data generates character string and a digital sign module receiving the adding character string generates digital sign data. A stop signal is sent out when the digital sign data is different from Harsy data, otherwise a exact informatino content global is sent out. The global transmitting is sotpped as soon as the stop signal is catched bysystem. The system can find any distortion for graded global and page content to ensure facticity and reliability of graded global.

Description

technical field [0001] The invention relates to a supervisory system for Internet information security, in particular to a hierarchical marking anti-tampering system. Background technique [0002] With the increasing popularity of the Internet, it is becoming an indispensable medium for information dissemination. Different from traditional media, Internet media has the characteristics of openness, extensiveness and rapidity of information dissemination. However, this has also brought unprecedented difficulties to Internet information security management. [0003] The illegal dissemination of online pornography, violence, gambling, drugs and other bad information will have a bad impact on the construction of spiritual civilization and the healthy quality of people's lives, especially on children's physical and mental health. Online political attacks, reactionary speeches and information have extremely adverse effects on the stability and unity of the country and the steady ...
