Abstract
The invention discloses a works copyright protection method, comprising the following steps: 1) constructing font libraries and numbering each font library; 2) coding the copyright to form a group of numeral strings with length as L; 3) typesetting a (K*L+i)th character in the works according to the font corresponding to an ith number in the numeral strings; wherein, K>=0 and i<=L; the numbers in the numeral strings correspond to the numerical symbols in the font libraries. In the method, by coding the copyright and presenting the codes in the typeset works in the form of fonts, the unauthorized persons are hard to crack the copyright and only can ruin the copyright for pirating, therefore, consumers and departments to crack down on fake goods can easily distinguish whether the works are pirated and the benefits of the consumers and copyright owners are safeguarded.
Description
Technical field
The present invention relates to a kind of Works copyright protection method.
Background technology
Information is carrier with the material medium, the sign that the various things existing waies motions in the transmission and the reflection world are posed.The accumulation of information and propagation are the bases of human civilization progress.Literal, photography, recording, video recording and the computer memory etc. of human invention can carry out information stores.Along with the high speed development of society, information storage means presents more and more stronger diversity, except the increase of continuous pursuit memory capacity, the raising of read or write speed, some unusual demands also occurred.
Networks development has brought more convenient, channel more efficiently for the propagation of information, and meanwhile, intellecture property is easier to be subjected to invading also become a problem that is difficult to avoid in network.In intellectual property protection, literary works have brought certain difficulty for its intellectual property protection because its singularity that only constitutes for literal makes it be difficult to load property right information.For strengthening the digital watermarking that antijamming capability designs, destroy a kind of technology that some important informations such as copyright information are remained exactly in order to resist some foreseeable attacks.
In the existing online literature works intellectual property protection method, a kind of employing picture issue literary works occurred, the mode of property right information is stored in while watermark in picture.Yet the anti-aggressiveness of this means is very poor, does not play the protective effect to works.At first for visible watermark, treatment measures such as fuzzy, covering are very easily eliminated.For invisible watermark, all can adopt comparatively simple image processing method to remove, as the back denoising point etc. that discolors.
Summary of the invention
The technical issues that need to address of the present invention provide a kind of Works copyright protection method, and this method can be difficult to crack and piracy with copyright information with in the present works of the form body of font.
For addressing the above problem, the technical solution used in the present invention is: a kind of Works copyright protection method, and this method may further comprise the steps:
1) makes up fontlib, and carry out numeral number for each fontlib;
2) copyright information is encoded, form the set of number character string, digit strings length is counted L;
3) the K in the works * L+i literal used the font of i numeral correspondence in the digit strings set type, K 〉=0 wherein, i≤L, the numeral number of the digital corresponding character library in the digit strings.
This method is further comprising the steps of: will generate picture format through the back works of setting type.
Described step 2) copyright information in is compiled into digital format, and coded system adopts any one in scale-of-two, three-shift, the quaternary, quinary, senary, septenary, scale-of-eight, the novenary.
Adopt the beneficial effect that technique scheme produced to be: the present invention is by encoding to copyright information, and will encode with in the present works of setting type of the form body of font, make the unauthorized person be difficult to crack copyright information, can only destroy copyright information and carry out piracy, whether pirate, safeguarded consumer and copyright owner's interests if can make consumer and departments to crack down on fake goods be easy to resolution.
Description of drawings
Fig. 1 is the Tang poetry " Jiang Xue " that adopts after the inventive method stores copyright information " 325 ";
Fig. 2 does not store " Jiang Xue " that copyright information is generated by No. 0 font " upright thin golden letters body ";
Fig. 3 does not store " Jiang Xue " that copyright information is generated by No. 1 font " Chinese row pattern ".
Embodiment
Below in conjunction with accompanying drawing the present invention is done and to describe in further detail:
The present invention is the solution that proposes for the solution problem of piracy, and it may further comprise the steps:
1) makes up fontlib, and carry out numeral number for each fontlib;
2) copyright information is encoded, form the set of number character string, digit strings length is counted L;
3) the K in the works * L+i literal used the font of i numeral correspondence in the digit strings set type, K 〉=0 wherein, i≤L, the numeral number of the digital corresponding character library in the digit strings.
Tang poetry as shown in Figure 1 " Jiang Xue " employing method of the present invention is embodied in copyright information " 325 " in the works and (is equivalent to works are encrypted), to prevent piracy.
The manufacturing process of works shown in Figure 1 is as follows:
At first make up fontlib, and carry out numeral number for each fontlib; This example has made up the fontlib of both font types " upright thin golden letters body " and " Chinese row pattern ", and wherein " upright thin golden letters body " font number is 0, and " Chinese row pattern " font number is 1; Certainly, can also make up more font, and be its numbering, for example can define 3-16 kind font, number 1-16 respectively.
Secondly copyright information is encoded, form the set of number character string, digit strings length is counted L; This example adopts the binary coding mode that copyright information " 325 " is encoded, and its digit strings that is converted to behind the scale-of-two is " 101000101 ", and the numerical character string length is 9; Wherein coded system is not limited to scale-of-two, can also be in three-shift, the quaternary, quinary, senary, septenary, scale-of-eight, the novenary any one, also can be other system modes, certainly in order to make it be difficult for being cracked, copyright information can be some numeral of relative complex, also can be that literal or letter are through the digital format after compiling, and (quantity of the font of structure is depended in the selection of coded system to choose suitable coded system, the number of fonts that makes up is many more, and alternative leeway is big more).
Then the K in the works * L+i literal used the font of i numeral correspondence in the digit strings to set type, K 〉=0 wherein, i≤L, the numeral number of the digital corresponding character library in the digit strings; In this example 1 of the 1st word correspondence " 101000101 ", adopt Chinese row pattern, 0 of the 2nd word correspondence " 101000101 ", adopt upright thin golden letters body, and the like (because the punctuation mark of different fonts is not easily distinguishable, punctuation mark is not counted in literal quantity in this example, if desired or in order to set type conveniently, also can count punctuation mark), form format shown in Figure 1.
At last, will generate picture format through the back works of setting type, picture format is convenient to issue on the network and anti-piracy, if publish books merely, this step can omit.
The embodiment of the invention makes up both font types; adopt binary coding that copyright information " 325 " is embodied (storage) in works; this can not be as limiting foundation of the present invention; those skilled in the art also can adopt other codings, fontlib to set type according to the present invention, but all can not break away from protection scope of the present invention.
Understand for convenience and be convenient to comparison, it all is " Jiang Xue " that No. 0 font generates that the present invention also provides, and as Fig. 2, all is that No. 1 font " Jiang Xue " that generate is as Fig. 3.
