Abstract

The invention discloses a method for preventing webpage character content from copy. The method comprises the following steps: dividing the webpage character content into a top layer and a bottom layer or more than two layers, wherein only part of the webpage character content is shown by each layer, and original content can be saw only by superposing all the layers top and bottom together; splitting original character information into two layers or more, and superposing all the layers to synthetize a new webpage, wherein the processes of splitting the original character information into two layers or more and superposing all the layers to synthetize the new webpage can be manually completed or can be completed by an automatic device; and displaying the new synthetized webpage by a browser. According to the method for preventing the webpage character content from the copy, the problems that a copy-prevention function is cracked and the webpage character content can be easily copied at low cost in the prior art are solved. Simultaneously, the invention discloses a device for automatically splitting the webpage character content and synthetizing the new webpage.

Description

The method and the device of the anti-copy of webpage word content

Technical field

The present invention relates to the internet web page technology, particularly a kind of method of word content anti-copy and device.

Background technology

World Wide Web is one of modal application on the internet, sees webpage with browser exactly.Info web on the internet is very abundant now, and the webpage Copyright Protection also becomes outstanding simultaneously.Get on because common webpage word content is easy to directly to be copied to other webpage or medium, the cost of bootlegging is very low.How increasing the difficulty of word content copy, improve pirate cost, is the problem that webpage word content anti-copy Technology Need solves.

Common webpage word content anti-copy technology comprises at present: 1, in webpage, embed invisible literal; 2, Javascript program anti-copy; 3, Javascript encrypts the webpage source code.Brief account is following:

Prior art one: in webpage, embed invisible literal

Principle: embed some invisible literal among the normal text content, the literal that for example calcaneus rete page or leaf background color is identical, little to the literal that has only a point etc.If duplicate stickup, will also copy over invisible literal and normal text is staggered in together.

Shortcoming:, remove invisible literal automatically than being easier to programming identification HTML code.

Prior art two: Javascript program anti-copy

Principle: the Javascript code with some specific functions joins in the webpage, for example prevents Ctrl-C, Ctrl-V, mouse point right button etc.

Shortcoming: forbidding browser Javascript script, copy-proof function will lose efficacy.

Prior art three: Javascript encrypts the webpage source code

Principle: can't see the webpage source code after encrypting, must move Javascript ability display web page content of text, therefore can not forbid the browser Javascript function.

Shortcoming: Javascript encrypts and can crack, and for example adds the document.write statement, with documentElement.outerHTML " the ultimate method that cracks " etc.

In sum, the copy-proof function of prior art has all had crack method, and the webpage word content is prone to duplicated by low cost.

Summary of the invention

The method and apparatus of a kind of word content anti-copy provided by the invention has had crack method in order to the copy-proof function that solves prior art, and the webpage word content is prone to by low-cost problem of duplicating.

A kind of method of word content anti-copy comprises:

Webpage text content be divided into two-layer or two-layer up and down more than, every layer only shows a part, all layers overlap up and down together can see original content;

Being split into two-layer or above process to original character information, and all range upon range of processes that add a synthetic new web page, all can accomplish by manual work or aut.eq.;

The new web page that is synthesized is shown by browser.

The device of a kind of automatic partition webpage word content and synthetic new web page comprises:

Shunt is used for assigning to each literal of original web page word content randomly in the different groups at random;

Randomizer is used to produce random digit, offers shunt at random;

Webpage individual layer maker, one every group, be used for assigning to the position of the literal of this group according to original web page, be placed in the layer of this group correspondence of synthesizing webpage, there is not the part of literal to leave a blank;

Webpage multilayer superimposer is used for being superimposed together multilayer, forms synthetic webpage.

The embodiment of the invention webpage text content be divided into two-layer or two-layer up and down more than, every layer only shows a part, all layers overlap up and down together can see original content; Being split into two-layer or above process to original character information is accomplished by manual work or computer program; All range upon range of processes that add demonstration are directly accomplished by browser, thereby have increased the difficulty of webpage word content copy, have improved pirate cost, have played the effect of webpage literal anti-copy.

Claims

1. the method for an anti-copy webpage word content is characterized in that, this method comprises:

Being split into two-layer above process to original character information, and all range upon range of processes that add a synthetic new web page, all can accomplish by manual work or aut.eq.;

The new web page that is synthesized is shown by browser.

2. the method for claim 1 is characterized in that, saidly is divided into two-layer method to webpage text content and specifically comprises:

Each literal in the original web page content of text, by at random or fixed form give a group among two groups;

Two groups of texts are put into respectively in the different layers, and the position of literal is consistent with the position in the original web page, do not have the part of literal to be left blank in every layer;

This two-layer relative position in synthetic webpage is to be superimposed up and down;
