Abstract
The invention discloses an information hiding system specified to htm/html, belonging to the field of information safety. The system provided by the invention aims at protecting user privacy and preventing user sensitive information from being peeped by others, so that the htm transmits private information while transmitting web pages, and a stored document which looks like an ordinary document practically contains the user privacy. The system hides information by interpreting and utilizing an htm/html label, so that the information hiding system specified to the htm/html is obtained.
Description
Technical field
The present invention is applied to information security, information digitalization, information transmission and mobile storage.
Background technology
Steganography is about Information hiding, does not promptly allow outside the recipient of plan anyone know the skill and the science of the transmission incident (and just the content of information) of information.English do " Steganography " of Steganography, one that derives from Johnny's Smith Streeter Mi Wusi looks it is relevant black magic, is actually in the book " Steganographia " of saying cryptography and Steganography.This book title derives from Greek, means " secret is write ".Information hiding is meant in design with during determination module, makes the customizing messages (process or data) that comprises in the module, is transparent for other modules that do not need these information.
HTML (Hyper Text Mark-up Language) is HTML (Hypertext Markup Language) or HTML, is the language that is most widely used on the present network, also is the main language that constitutes web document.The descriptive text that html text is made up of HTML order, HTML are ordered can comment, figure, animation, sound, form, link etc.The structure of HTML comprises head (Head) and main body (Body) two large divisions, and wherein head is described the required information of browser, and main body then comprises the particular content that will illustrate.
At three's characteristic, we with it comprehensively to one.At the Information hiding of htm/html, promptly at the information steganography of htm/html, it is as a whole after exactly sensitive information being encoded by packing it to be done, and mainly solves different types of information, such as a plurality of files.After information package, we are amplified to original octuple with it, and information is embedded in the original html carrier according to specific algorithm, the new information that forms utilizes html from resolving cleverly, html after the camouflage and common html do not have any difference in appearance, by pretending oneself, the fascination assailant, make and transmit on the basis of original information, for a green channel has been opened in the transmission of sensitive information.Even sensitive information can also make that information is unfortunate by cryptographic algorithm and leak, still leave last one barrier, for the safe transmission of information provides new fender wall one.
Summary of the invention
1, the present invention is a kind of Information hiding system at the htm/html text formatting, and this system is made up of htm/html hypertext identification module, information gathering module, message processing module and extraction module.
2, summary of the invention 1 described two-dimensional barcode information index generation module comprises following performing step:
(1) the htm/html text by serializing after, we regard it as bitstream,, according to the explanation of official to htm/html its information are divided into for bitstream
<HTML>
<HEAD>
<title>，<base>，<link>，<isindex>，<meta>
</HEAD>
<BODY>
The text of html file is write here ...
</BODY>
</HTML>
(2) on 1 basis, calculate the content of text
(3) calculating the then whole hiding process of failure counts out
3, summary of the invention 1 described information gathering module comprises following performing step:
(1) information that needs are hidden is packed by the algorithm of standard;
(2) the file sequence after will packing turns to special symbol and further processes for message processing module;
4, summary of the invention 1 described message processing module comprises following performing step:
(1) in 2 (1) text messages that extracted, find suitable position and with this position as the inlet that hides Info, the selected of inlet gone up according to specific algorithm generation.
(2) inlet of the inlet of Information hiding and information extraction judges at first as sharing point whether original text is processed, if processed, then will once conceal earlier in this information and reject.
(3) amplify by the information of 3 serializings according to 1: 8 ratio, in its html that writes direct, the sequence after the amplification is according to the resolution rules of html, and these information naked eyes are sightless.
(4) information extraction, leaching process and hiding process are similar, obtain the entrance after, whether have information, if do not have, then extract failure if detecting; Otherwise the ratio according to 8: 1 is dwindled information, dwindles the information after the back gained is packing, and information is unpacked promptly obtains raw information.
Embodiment
Purpose of the present invention, advantage and characteristic can be clearer by detailed description and graphic the working as of following several embodiment, and these embodiment illustrate as embodiment, its objective is to convenient the present invention is described in detail, but not in order to limit the present invention.Case study on implementation-coding:
Appoint to give one section htm web document, we with
Www.baidu.comWebpage is an example, generates a htm web page files that contains latent write information.Suppose that the information that will hide is ' china '. learn china=63H by inquiry ascii code table, 68H, 69H, 6EH, 61,H=0,110 0011 (B), 0,110 1000 (B), 0,110 1001 (B), 0,110 1110 (B) 01100001 (B), this information is obtained 09 20 20 09 09 09 20 20 09 20 20 09 20 09 09 09 09 20 20 09 20 09 09 20 09 20 20 0,920 20 20 09 09 20 20 09 09 09 09 20 such information after by algorithm three serializings just be exaggerated 8 times, and, can directly be written in the content of webpage because these numerals all are sightless in webpage or notepad.Suppose we with before the body for this reason information slip into mouth, then directly this sequence is inserted in the urtext and gets final product.
Case study on implementation-decoding:
Because in advance we know at＜body〉be the place of latent write information before,＜body〉detect whether there is the latent mark of writing before, if exist, then remove to seek information header, information after finding is the 09 and 20 pseudobinary streams of forming, only need do a decoding of 8: 1 can obtain original data stream, by this being flow to the information before row operation finally obtains hiding.To obtain 09 20 20 09 09 09 20 20 09 20 20 09 2,009 09 09 09 20 20 09 20 09 09 20 09 20 20 09 20 20 20 09 09 20 20 09 09 09 09 20 sequences by scanning, according to 09 is 0,20 is 1 principle, obtain 0,110 001101101000011010010110111001100001, get 6368696E61 after being converted into 16 systems, the inquiry ascii table gets china. and hides preceding information just consistent.
