Abstract

The invention discloses a method for preventing screen contents of a webpage from being copied. The method comprises the following steps of: randomly separating the screen contents of a webpage into multiple parts; quickly and cyclically displaying the contents of the plurality of parts in a browser so that naked eyes can see the whole webpage on the basis of the characteristic of persistence of vision but the complete screen contents of the webpage cannot be copied from a screen; using a floating icon moving slowing to stop screen capture software from obtaining the screen contents of the webpage through automatic overlying and multiple screen capturing. Through adoption of the method, the problem that the anti-copy function in the prior art can be cracked and the screen contents of the webpage can be easily copied from the screen with low cost. The invention also discloses a device for preventing contents of the webpage from being copied from the screen.

Description

The method and the device thereof of the anti-copy of webpage screen content

Technical field

The present invention relates to the internet web page technology, the method for the anti-screen copy of particularly a kind of web page contents.

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.Because common web page contents comprises literal, picture etc., all be easy to directly gone out the webpage picture by screen copy, being put into other webpage or medium gets on, and the cost of bootlegging is very low.How increasing the difficulty of the anti-screen copy of web page contents, improve pirate cost, is the problem that the anti-screen copy Technology Need of web page contents solves.

Common webpage word content anti-copy technology comprises at present: 1, forbid or empty clipbook with technology such as Javascript; 2, with special plug-in units such as ActiveX.Brief account is following:

Prior art one: forbid or empty clipbook with technology such as Javascript.

Principle: during with Print Screen key copy screen content, can copy to clipboard.Forbid or constantly empty clipbook and just can stop this screen copy.Some is grabbed screen software and also uses clipbook, and this technology is effective equally to these softwares.

Shortcoming: a lot of screen copy softwares have all got around clipbook, make this technical failure.

Prior art two: with special plug-in units such as ActiveX.

Principle: than Javascript further, use the plug-in unit of special exploitation to defend the powerful screen software of grabbing.

Shortcoming: can resist the powerful screen software of grabbing, mean that the function of plug-in unit must be very strong, also mean the basic security property restriction that must break through browser on the other hand, somewhat similar rogue software.Most of browser does not allow this plug-in component operation that potential safety hazard is arranged.

In sum, the copy-proof function of prior art or crack method has been arranged, or compatibility or security are relatively poor, can not in the browser of the common level of security of major part, use.

Summary of the invention

The method and apparatus of the anti-screen copy of a kind of web page contents that the embodiment of the invention provides; Copy-proof function in order to solve prior art has perhaps had crack method; Or compatibility or security are relatively poor, the problem that can not in the browser of the common level of security of major part, use.

A kind of method of web page contents anti-copy comprises:

Split into a plurality of parts to the webpage image content at random;

Rapid Cycle shows the content of a plurality of parts in browser, utilizes eye storage characteristic, makes naked eyes can see whole webpage, but screen copy can not get complete webpage image content;

Stop with the float icon that slowly moves and to grab the automatic stack of screen software and repeatedly grab screen and obtain the webpage image content.

A kind of device of anti-screen copy web page contents comprises:

Image splitter is used for assigning to each pixel of original web page picture or each block randomly in the different groups;

Randomizer is used to produce random digit, offers image splitter;

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

A unsteady layer maker is used for being generated as a semitransparent layer that synthesizes webpage to icon;

Webpage multilayer superimposer is used for being superimposed together multilayer, adds the dynamic web page code that Rapid Cycle shows each layer again, forms synthetic webpage.

The present invention splits into a plurality of parts to the webpage image content at random; Rapid Cycle shows the content of a plurality of parts in browser, utilizes eye storage characteristic, makes naked eyes can see whole webpage, but screen copy can not get complete webpage image content; Stop with the float icon that slowly moves and to grab the automatic stack of screen software and repeatedly grab screen and obtain the webpage image content, thereby increased the difficulty of web page contents screen-picture copy, improved pirate cost, played the effect of anti-screen copy web page contents.

Description of drawings

The fractionation that Fig. 1 provides for the embodiment of the invention, merging webpage image content prevent the method synoptic diagram of screen copy;

A kind of automatic partition webpage image content that Fig. 2 provides for the embodiment of the invention, synthetic again and dynamically show the apparatus structure synoptic diagram of new web page;

Fig. 3 is the environment synoptic diagram of the anti-screen copy web page contents of the embodiment of the invention;
