Abstract

The invention discloses a method and device for preventing web page words from being copied. The method for preventing the web page words from being copied comprises the following steps that content of a web page text is divided into an upper layer and a lower layer or more than two layers, each layer only displays a part of the content, and the original content can be seen only if all the layers are vertically overlapped together; the process that the original word information is divided into the two layers or more than two layers, and the process that all the layers are overlapped to compose a new web page can be completed through manual work or an automatic device; the new web page which is composed is displayed by a browser. The method for preventing the web page words from being copied solves the problems that a cracking method of an existing anti-copying function of the prior art exists and the word content of the web page is copied at a low cost. The invention also discloses a device for automatically separating the word content of the web page and synthesizing the new web page.

Description

Method and the device thereof of the anti-copy of webpage word

Technical field

The present invention relates to the internet web page technology, particularly a kind of method of preventing webpage character content from copy.

Background technology

World Wide Web is one of modal application on internet, sees webpage with browser exactly.Info web on internet is very abundant now, and the webpage Copyright Protection also becomes outstanding simultaneously.Because common webpage word content is easy to be gone on other webpage or media by direct copying, the cost of bootlegging is very low.How increasing the difficulty of word content copy, improve pirate cost, is the problem that the preventing webpage character content from copy Technology Need solves.

Common preventing webpage character content from copy technology comprises at present: 1, embed invisible word in webpage; 2, Javascript program anti-copy; 3, Javascript encrypts the webpage source code.Simply be described below:

Prior art one: embed invisible word in webpage

Principle: embed some invisible words, such as the identical word of calcaneus rete page background color, little word to only having a point etc. among the normal text content., if copy stickup, will also copy over invisible word, and normal text is staggered in together.

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

Prior art two: Javascript program anti-copy

Principle: join in webpage with the Javascript code of some specific functions, such as preventing 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 easily copied by low cost.

Summary of the invention

The method and apparatus of a kind of preventing webpage character content from copy that the embodiment of the present invention provides, had crack method in order to the copy-proof function that solves prior art, the problem that the webpage word content is easily copied by low cost.

A kind of method of preventing webpage character content from copy comprises:

Webpage text content be divided into up and down two-layer or two-layer more than, every layer only shows a part, all layers coincide with the upper and lower to be superimposed can see original content;

Original character information being split into two-layer or above process, and all stacked processes that add a synthetic new web page, all can be completed by artificial 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:

Random shunt, be used for each word of original web page word content is assigned in different groups randomly;

Randomizer,, for generation of random digit, offer random shunt;

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

Webpage multiple-layer stacked device, be used for multiple-layer stacked is arrived together, forms synthetic webpage.

The embodiment of the present invention webpage text content be divided into up and down two-layer or two-layer more than, every layer only shows a part, all layers coincide with the upper and lower to be superimposed can see original content; Original character information is split into two-layer or above process to be completed by artificial or computer program; All stacked processes that add demonstration are directly completed by browser, thereby have increased the difficulty of webpage word content copy, have improved pirate cost, have played the effect of webpage word anti-copy.

Claims

1. the method for a preventing webpage character content from copy, is characterized in that, the method comprises:

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

2. the method for claim 1, is characterized in that, describedly webpage text content is divided into bilevel method specifically comprises:

, each word in the original web page content of text, by random or fixed form, give among two groups one group;

Two groups of texts respectively are put in one deck of synthetic webpage, and the position of word is consistent with the position in original web page, do not have the part of word to be left blank in every layer;

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

The layer that this requires the webpage of indication, include but not limited to the defined web page element of html tag " div " or " layer ".

3. the method for claim 1, is characterized in that, describedly webpage text content is divided into the two-layer above method in up and down specifically comprises:

Each word in the original web page content of text, give among N group one group by random or fixed form, wherein N is the natural number greater than 2;

N group text respectively is put in one deck of synthetic webpage, and the position of word is consistent with the position in original web page, does not have the part of word to be left blank in every layer;

The relative position of this N layer in synthetic webpage is to be superimposed up and down successively;

4. method as claimed in claim 2 or claim 3, is characterized in that, according to following formula, determines the layer L that i word in the original web page content of text will be assigned to _i:
