Problems solved by technology

There are three main types of existing web page information hiding methods: 1) based on tag attribute character case and space characters, this type of method has a large hiding capacity, but the hidden information is easy to be removed; 2) methods based on equivalent marks,

Embodiment

[0055]A specific embodiment of the present invention is a method for protecting webpage links based on control character coding steganography, comprising the following steps:

[0056] A. Web page segmentation

[0057] According to the original webpage file F, F={f r |r=1,2,...,N} The terminator of the link tag divides the original webpage file F into M+1 webpage blocks; the first M webpage blocks are link blocks F i , F i ={f r |r=T i +1,T i +2,...,T i +t i} is a link block; among them, f r Indicates the character whose position number is r in the webpage file F, N is the number of characters contained in the webpage file F; i is the link block F i The serial number of i=1,2,...,M; T i For the i-1th link block F i-1 The ordinal number of the end character position, T 1 = 0, t i is the i-th link block F i The total number of characters; the M+1th web page block F M+1 From the position sequence number in the original web page file F from T M +t M All characters b...

Abstract

The invention relates to a webpage link protection method based on control character coding and steganography. Watermark information can be embedded through selected control characters which are not displayed at a browser end, and thus link information in a webpage can be protected. First, the webpage is partitioned into blocks according to links, watermark information with any bit is generated according to all the characters of all the sub-blocks and coded into corresponding control characters to be embedded into the webpage, and a webpage with watermarks is generated; in detection, whether the link blocks are tampered or not is judged by comparing the relations between different bit numbers and thresholds of extracted watermarks and reconstructed watermarks corresponding to the link blocks; when tampered link blocks are detected, all attribute information including link addresses is deleted, and blocks are marked with warning mark information, so that a prompt is given to a user. Through the webpage link protection method based on control character coding and steganography, link block information in the webpage can be effectively protected; when the link blocks are tampered, the tampering can be detected out in time, and false information is prevented from being propagated, so that negative effects of tampered link blocks on images ad business of enterprise and public institutions are reduced.

Description

technical field [0001] The invention relates to a method for protecting web page links based on control character coding steganography. Background technique [0002] With the development of network and multimedia technology, website has become one of the important ways for people to obtain information. According to the statistics of the National Internet Emergency Response Center (CNCERT) (National Internet Emergency Response Center. CNCERT Internet Security Threat Report - December 2013), the number of tampered websites in mainland China in December 2013 was 4845, of which the number of counterfeit pages was 303 One, the webpage of the website was counterfeited and tampered with, which affected the progress of the normal business of enterprises and institutions. As a method to effectively protect the authenticity and integrity of webpage content, webpage fragile watermarking has important research significance and broad application prospects. [0003] In order to detect t...
