Description

A kind of generation method of public place admission ticket

Technical field

The invention belongs to field of information processing, the generation method of a kind of public place admission ticket.

Background technology

Along with the fast development of China's economy, the applicating and exploitation of barcode technology is by bill anti-counterfeit, and commodity counterfeit prevention etc. is each The concern in field.

Bar code is to be managed postgraduate's invention of subject by the Ha Fu university of the U.S. the earliest, and conception originally is: Gu Ketong Cross inventory and select oneself required commodity, delivery of cargo window will be taken with the card got with punched-card machine corresponding to these commodity Mouthful, so that it may obtain required commodity.This card correction quantity in stock can be passed through in shop, or as asking for the application of expense to client Single.As so advanced logistics means, but do not popularized because of the cheapest of labour force at that time.Nowadays in the whole world Each supermarket, in shop on the commodity of display, bar code is ubiquitous.Outwardly bar code because of each record information lines account for According to the biggest area, therefore it is easier recognition, in fact just as the area that occupies of this bar code is relatively big, not only affects commodity Packaging attractive in appearance, is additionally, since and needs more special optical system, is the most also the recognizer cost root that is difficult to reduce.

Enter the later stage of the eighties, due to the particular/special requirement of gem, quasiconductor, medicine and machinery industry, need in print The information realizing more capacity on brush media describes, and the particularly application of bar code brings huge receipts to enterprise Benefit, people concentrate sight the research and development having pointed to two-dimensional bar code.The motion of the most a series of two-dimensional bar codes is fallen over each other to come out of steamer.Just It is still to have the pass of entitled " the generation method of message code and message code " (JP 2011-134211) to Japan in 2011 Patent in two-dimensional bar code is disclosed.But the most conventional two-dimensional bar code is not broken through technically compared with a bar code The progress of property.The most tightly with the square representative information " 1 " of black, and with the square representative information " 0 " of white, it is still desirable to specially Printing space, it is impossible to utilize printing image embedment information.Particularly, two-dimensional bar code brings damage to printing the attractive in appearance of image Evil, this be make us always puzzled main cause.It is exactly on remote reading, owing to needs are focused, the most also one Directly there is reading speed slow, the problem that precision is low.

In the later stage nineties, people start to consider to play sound on leaflet, it is desirable to have bigger information to describe ability The exploitation of code.Japan has concentrated Olympus whole strength to propose with entitled " code printing equipment and being suitable for Code print media " (Patent 8-208196) be a large amount of patent applications of representative.This motion proposes the point bigger with four summits As datum mark, several two-dimensional bar code modules can be carried out and connect, therefore voice data directly can be remembered by this bar code State.But this two-dimensional bar code, except the size of each dot matrix is less than ordinary two dimensional bar code, and can carry out two-dimensional bar code Outside module connects, little with the difference of ordinary two dimensional bar code.This code be once expected to will have the biggest economic benefit with should By prospect, but eventually because needing to carry out the scanning of larger area during recognition, its operability extreme difference, could not finally realize original Expected value and come to an end.

Since entering 2000, the technology of two-dimensional bar code occurs in that the progress advanced by leaps and bounds.For a dot matrix, by commonly The information of the single bit of bar code describes, and the information having developed into many bits describes.Occupy the common of independent space by needing Two-dimensional bar code has developed into without occupying separate space, directly imbeds information in printing image.Sweden in this area A Nu (Anoto) company thoroughly has applied for patent (the special table 2003-of entitled " being applicable to the symbolization paper optically read " 511761), the patent proposes and be placed on four positions of imaginary centres by a dot matrix, can represent four information, this is The blank that many bit informations describe.But, this patent is only limited in this narrow scope of imaginary centres, and only Only consider to describe the coordinate figure of the two-dimensional space of paper medium, and the description of code information can not be realized.Opening in this patent Dagger-axe Reed (Grid) company giving Japan also been proposed entitled " data inputting method based on dot pattern " (W2004/ 084125).This patent proposes on four summits of a given little rectangle, lays four benchmark dot matrix, with these four On the basis of the imaginary centres that benchmark dot matrix is formed, an information dot matrix is placed on eight positions of imaginary centres, can table Show eight information.At that time, this company thought that using these four summits is the core invented, and therefore pushed up the name of company Point (Grid) this word, but, this motion is limited to the imaginary centres that formed by four apex reference point battle arrays, and this is narrow In the range of.An information dot matrix to describe inadequate science in efficiency in information, the most just corresponding to four apex reference point battle arrays in fact It is to say that four apex reference point battle arrays might not have to there is meaning.

Half-tone screen code patent is with " can note down the half-tone screen code control method of data in a large number " for topic on paper in the meantime (CN1598873), except for printing net-point, in the case of the gray scale system not changing site, by changing the difference of site Shape, diverse location, different directions, centralization and decentralization etc. can describe many bit informations.This patent, for burying on printed medium Enter information and provide the most theoretical and method.The information that A Nutou (Anoto) company of the most above-mentioned Sweden is proposed describes Phenomenon, can essentially be construed to provide a same color, the dot matrix of formed objects, be arranged in one according to same intervals Shading, in the case of the size not changing dot matrix, by changing the position of dot matrix, so that it may describe many bit informations.Utilize a little The diverse location of battle array describes why information obtains such concern, just as it can realize maximum by minimum dot matrix Information record, the most so has the shading of information simultaneously it is also contemplated that screen characteristic, its knot after with printing picture registration Really, the impact on printing image can accomplish minimum, say, that such dot matrix way is suitable for the information for printing image Embedment.

The public place paper medium admission ticket used at present, it is impossible to realize while low precision prints, at admission ticket The relevant information of upper record nominal value, is unsuitable for the application of automatic ticket checking system, and is prone to forge, but due to paper medium admission ticket Cost low, range of application is widely.The two-dimensional bar code used on some admission tickets at present non-information embedment code, two The information characteristics spot size of dimension bar code is very big, takes up room, is difficult to hide, affects the attractive in appearance of nominal value, and need special knowledge Other device is just recognizable.The anti-counterfeiting power thus resulting in admission ticket is low, and the event of extensive ticket re-selling happens occasionally.

The most how to realize, on the admission ticket that low precision prints after embedment information, the most not affecting the aesthetic of nominal value. Meanwhile, also there is antifalse effect, be present patent application problem to be solved.

Distribution after combining according to the dot matrix of certain purpose refers to: on the basis of ordinary two dimensional bar code dot matrix, according to having The quantity of dot matrix is equal such as Figure 10 with the quantity without dot matrix；Under conditions of the quantity of recordable information is equal, there is the number of dot matrix Measure minimum such as Fig. 6-8, i.e. by the information of minimum dot matrix record maximum quantity；In the condition that the quantity of recordable information is equal Under, without the minimum number of dot matrix, i.e. with information such as Fig. 9 of the minimum record maximum quantity of quantity without dot matrix；It is similar between dot matrix Degree is minimum such as Figure 10；Dot matrix is evenly distributed such as Figure 11, and the dot matrix combined result that purpose necessary to other is condition.

Fig. 3 is the schematic diagram of the different many bit informations of directional spreding record by dot matrix.Site 301 is by information point The New Two Dimensional bar code of battle array 302 and 303 composition, the different directions constituted according to information dot matrix 302 and 303 represents different letter Breath.

In figure 3, figure a can represent that information 0, figure b can represent that information 1, figure c can represent information 2, figure D can represent information 3.New Two Dimensional bar code a, b, c, d obviously can regard as by different directions and different electromagnetic waves The direction of propagation, different Mechanics Vector results realizes computer many bit informations record.

Information shown in Fig. 3 describes the lattice arrangement of module can regard a combined result during dot matrix combines entirely as, The i.e. combination of dot matrix.

Fig. 4 is the schematic diagram by the different many bit informations of graphic recording computer.In the diagram, figure a can represent Information 0, figure b can represent that information 1, figure c can represent that information 2, figure d can represent information 3.

Information shown in Fig. 4 describes the combination knot that the lattice arrangement of module can also be regarded as during dot matrix combines entirely Really, i.e. the combination of dot matrix.

Fig. 5 is the schematic diagram being described module by the information concentrating site and dispersion site to be constituted.As it is shown in figure 5, by one All of printing points in individual site constitutes concentration site a and at least scattered site composition that a dot matrix is constituted Spaced point b constitute the example of fine roots that can imbed information.Concentrating site a to be set as the value of information " 1 ", disperse site b It is set as the value of information " 0 ".On the contrary, can be set as that concentrating site a the value of information " 0 ", dispersion site b are set as the value of information " 1 ".

It addition, in order to constitute standard dot pattern, as it is shown in figure 5, the high H of point 501 concentrating site a₅₀As two prints The diameter value of brush point (the minimum printable size of printer), the width W of the point 501 concentrating site a₅₀As a printing points Diameter value.The point 502 of dispersion site b functions only as the effect of shading gray scale homogenization, is not used in identification, dispersion site The height H of point 502₅₁With width W₅₁All as the diameter value of a printing points.The height of site is H₅₂, width is W₅₂。

As it is shown in figure 5, can regard amplitude modulation mode as concentrating site a is (AM) screen, dispersion site b is regarded as tune Frequently mode is (FM) screen.I.e. can record information according to the different dot pattern of modulation system.

It addition, because low frequency number site can be regarded as concentrating site a, disperses site b to regard altofrequency number site, institute as With it may be said that concentrating site a and disperseing site b is to become member record information according to different frequency number.

And then, the gray value concentrating each site of site a is big, and the gray value of each site of dispersion site b is little, so Alternatively concentrate site a and dispersion site b be the different gray values for a point record information.

In other words, the size concentrating the point of site a is big, and the size of each point of dispersion site b is little, it is possible to say concentration Site a and dispersion site b is to record information according to the dot pattern varied in size.

About above content, it is also possible to there is a lot of meanss of interpretation.If but identical with above dot pattern, Within belonging to the scope of the present invention.

Fig. 6 is to be realized computer many bit informations note by information dot matrix according to the result of different positions and phase-modulation The schematic diagram of record.As shown in Figure 6: figure (a) can represent information 0, figure (b) can represent information 1, and figure (c) can be with table Show that information 2 and figure (d) can represent that information 3, figure (e) and figure f can represent positioning datum information.

It addition, Fig. 7 is the dot matrix 701 that the given information shown in Fig. 6 describes module, by information dot matrix 702 not With the some transmitting signal of physical phase-modulation (PM) constituted (a, b, c) and (d) four kinds of outs of phase modulation (PM) The schematic diagram of result.

The derivation of the mathematical model of the dot pattern being made up of phase-modulation shown in Fig. 6 with Fig. 7 is as follows.

If the function of the dot pattern being made up of the square lattice of interval T is that (x, y), then (x, after y) being standardized for ζ for ζ Result as follows:

$\mathrm{\ζ}(x,y)=\underset{i=-\mathrm{\∞}}{\overset{\mathrm{\∞}}{\Σ}}\underset{j=-\mathrm{\∞}}{\overset{\mathrm{\∞}}{\Σ}}{\mathrm{\ζ}}_{i,j}\×\mathrm{\η}(x-i\×T,y-j\×T)$

Here, the signal response function for the dot pattern of phase-modulation is:

η (x-i × T, y-j × T)=η (m × T, n × T)

The horizontal m-th being standardized, and the centre coordinate value of the point of vertical n-th dot pattern be (m × T, n × T), additionally dot pattern each put relative centre coordinate (m × T, n × T) displacement function be [ε (and m, n), δ (m, n)], that , the set D of dot pattern is as follows:

η (m × T, n × T)=η { ε (m, n) × T, δ (m, n) × T}+

η [1-ε (m, n)] × T, [1-δ (m, n)] × T}+...+

η [∞-ε (m, n)] × T, [∞-δ (m, n)] × T}+

η [1+ ε (m, n)] × T, [1+ δ (m, n)] × T}+...+

η [∞+ε (m, n)] × T, [∞+δ (m, n)] × T}

I.e.

[m × T+ ε (m, n) × T], [and n × T+ δ (m, n) × T] } ∈ D

Thus, input by signal response function η [i+ ε (m, n)] × T, [j+ δ (m, n)] × T} substitute into after phase-shifted Amount ζ_{M-i, n-j}Output signal be:

Here, control ε (m, n) and (m, n), so that it may realize for the transmitting signal { phase-modulation of ζ m, n}.

Information shown in Fig. 6 describes the combination knot that the lattice arrangement of module still can be regarded as during dot matrix combines entirely Really, i.e. the combination of dot matrix.

Fig. 8 is one and is distributed and the signal of the many bit informations of phase-modulation result record by the diverse location of information dot matrix Figure.As shown in Figure 8: 800 describe module image for information.801,802,803 and 804 is information dot matrix, each point according to Can represent numerical value 0 to 3, i.e. 2 bit informations shown in Fig. 6, four points just can represent numerical value 0 to 255, i.e. 8 bit letters Breath.Each point also may indicate that numerical value 0 to 7, i.e. 3 bit informations, and four points just can represent numerical value 0 to 4096, i.e. 12 Individual bit information.805,806 is horizontal direction positioning datum dot matrix, is mainly used in as information dot matrix 801-804 in level side To positioning datum, or the horizontal direction initial value of phase-modulation, 808,809 is vertical direction positioning datum dot matrix, mainly uses In as information dot matrix 801-804 at the positioning datum of vertical direction, or the vertical direction initial value of phase-modulation.

Information shown in Fig. 8 describes the information recording method of module, it is also possible to regard fixed by information dot matrix relative level as For dot matrix, and the diverse location distribution of perpendicular positioning dot matrix records many bit informations.Information shown in Fig. 8 describes module Lattice arrangement can regard a combined result during dot matrix combines entirely, the i.e. combination of dot matrix as.

Information describes module character library lattice arrangement and is possible not only to be 1*1 dot matrix, 1*2 dot matrix, 3*3 dot matrix, it is also possible to be 3* 4, or 4*4 dot matrix, or 4*5, or 5*5 dot matrix, or 5*6 dot matrix, or 6*6 dot matrix, or n*n dot matrix, as long as what the present invention proposed Geometric or physical lattice arrangement, within the character library being made broadly falls into the interest field of the present invention.

Fig. 9 is under conditions of the quantity of recordable information is equal, without a kind of code form of the minimum number of dot matrix.Figure 9 (a) represents information " 0 ", and Fig. 9 (b) represents information " 1 ", and Fig. 9 (c) represents information " 2 ", and Fig. 9 (d) represents information " 3 ", Fig. 9 (e) Expression information " 4 ", Fig. 9 (f) represents information " 5 ", and Fig. 9 (g) represents information " 6 ", and Fig. 9 (h) represents information " 7 ", and Fig. 9 (i) represents Location information.The information recording ratio of the octal system information macroscopic view code shown in Fig. 9 is 0.33, and printing area rate is 8/9.Printing surface Long-pending rate is the highest, under conditions of the quantity of recordable information is equal, without the minimum number of dot matrix, i.e. with minimum without point The information of battle array quantity record maximum quantity.

Figure 10 is the dot matrix distribution schematic diagram that between dot matrix, similar degree is minimum.Between code, the implication of similar degree is exactly between code Similarity degree, the biggest representative of its value is the most similar, and resolution is the lowest, identifies the most difficult；Otherwise, between code, similar degree is the least, differentiates Rate is the highest, and it is the easiest to identify.

S is set in half-tone screen code_kIt is that code is long for message code, n, when m is the quantity of code, between described half-tone screen code Big similar degree A_maxIt is to be expressed from the next:

[formula 1]

Dmin=min d (S_k, S₁)

[formula 2]

$A_{\max }=\frac{n-d_{\min }}{n}$

In formula: d (S_k, S₁) it is code S_kWith S₁Between distance i.e. code between the number of different code position, k, l=0,1, 2 ... m-1.

Figure 10 is that between code, maximum similar degree is the example of the half-tone screen code of less than 1/2.In these 15 codes each other The number of value bit different between immediate any one group of code is greater than the quantity of the half equal to code length.At net In the identification of screen coding, there is higher recognition resolution.

Figure 11 is the dot matrix distribution schematic diagram that the combination configuration information by dot matrix describes module.As shown in figure 11: realize Another means of New Two Dimensional bar code, be common two-dimensional bar code dot matrix be distributed set in find out one group have include print The code distribution of brush screen characteristic, or dot matrix distribution is relatively uniform, or the i.e. similar degree that between code, Hamming distances is maximum is Little, or the combined result of other purposes, or the recognition feature according to fixed focal length, the lattice dimensions of code is reduced, structure Become a New Two Dimensional bar code.

Figure 11 is the example of the information description dot matrix module of 20*20 dot matrix, and in figure, 1100 is the information description of 20*20 dot matrix Dot matrix module, has a little 1101 expression information dot matrix " 1 ", no point 1102 expression information " 0 ", dot matrix 1103 expression location base around Battle array on schedule.As shown in figure 11, in the set that the dot matrix of common two-dimensional bar code is distributed, according to printing net screen characteristics, find out point Cloth is more uniform, a kind of combination distribution that dot matrix is separated from each other, such as in each group of 6*6 dot matrix of common two-dimensional bar code, by The 3*3 dot matrix that each group is separated from each other constitutes the New Two Dimensional bar code shown in Figure 11, point one byte of matrix representation of each 3*3 Information, it can be seen that compared with ordinary two dimensional bar code, each dot matrix is separated from each other, and dot matrix distribution ratio is more uniform, although with above-mentioned New Two Dimensional bar code is compared, and has some irregular distributions, but wants owing to describing the quantity of information of module record than above-mentioned information Greatly, therefore, there is certain Practical significance.

It addition, for ordinary two dimensional bar code according to the needs of application, such as increase the Hamming distances between code, reduce generation The similar degree of intersymbol, improves code distributing homogeneity, the maximization of code distribution area, minimizing of code distribution area Deng, it is possible to achieve various dot matrix combine, and form various code form, meanwhile, can generate various point The character library of battle array pattern, within these all belong to the scope of the present invention.

Figure 12 is the dot matrix distribution schematic diagram that the another kind of combination configuration information by dot matrix describes module.Such as Figure 11 institute Show: 1201 expression perpendicular positioning dot matrix, the interval of 1202 expression perpendicular positioning dot matrix, 1203 expression horizontal location dot matrix, 1204 Representing the interval of horizontal location dot matrix, 1205 represent information dot matrix.

Approximating with ordinary two dimensional bar code, here with all of community in region shared by New Two Dimensional bar code, i.e. having can The dot matrix region of capacity of decomposition describes the information of a bit, and in each community, information " 1 " and information " 0 " can use binary map The B&W of picture represents, it is also possible to represent by the difference of the gray value of coloured image entirety, it is also possible to different colors is come Represent, it is also possible to less to image contributions by the bitmap of coloured image, be distributed obvious low level immediately, according to Figure 12's Rule and information content are replaced, and in a word, in each community, information " 1 " and information " 0 " are as long as ensureing capacity of decomposition Under conditions of, realize information by difference and describe.

Figure 13 is that the color region utilizing RGB color and CMYK color space to convert realizes showing of anti-counterfeit printing It is intended to.The color space that general scanner is used is RGB form, and the color space that common printing presses is used is CMYK Form.As shown in figure 13: if color selecting is in the color region of RGB/CMYK, the image gone out printed by it can be swept Retouch instrument replicate faithfully and print out, i.e. this color region is reproducible region.The most as shown in figure 13: if selecting RGB color The image gone out printed by region or CMYK color region can not be replicated faithfully by scanner.Such principle is utilized to realize The effect of anti-counterfeit printing.Such as, the color selecting K version of New Two Dimensional bar code, use can be printed on New Two Dimensional bar code The image of the trichroism composition of CMY, and for example the color of image of the fruit trichroism composition of CMY is relatively deep, the actual composition with black, but due to Color of image with the trichroism composition of CMY does not contains carbon, is transmission to infrared ray, the most do not affect the New Two Dimensional bar of K version The recognition of code.But, if above-mentioned image is replicated by scanner, printed by the image that goes out, having of the trichroism composition of originally CMY The color of image of the composition of black, will be reflected in K version when point version, send out with the original New Two Dimensional bar code in K version Raw conflict, therefore can not correctly read the New Two Dimensional bar code in K version, thus reach false proof effect.

Figure 14 is addition camouflage color dot matrix, the schematic diagram of camouflage color labelling in New Two Dimensional bar code.As shown in figure 14: 1401 are Bill images, 1402 is New Two Dimensional bar code, and 1403 is camouflage color dot matrix, and 1404 is camouflage color labelling.New Two Dimensional bar code uses can The ink of recognition property, powdered ink, a kind of printed material in ink prints, and here, the ink of the property distinguished refers to: use readability Printed material implements printing on print media, and the image after its printing, at illumination and the corresponding image sensing of institute's standing wave length Under device, can be read by imageing sensor.Camouflage color dot matrix and camouflage color labelling use the ink of the non-property distinguished, and powdered ink, in ink A kind of printed material print, here, the ink of the non-property distinguished refers to: use non-readable printed material to implement on print media Printing, the image after its printing, under the illumination and corresponding imageing sensor of institute's standing wave length, can not pass through image sensing Device reads.Such as: use infrared illumination, and when infrared imaging sensor is distinguished, with this understanding, common C, Each color of M, Y by blank sheet of paper reflective after all present random color that is transparent, that the most no matter synthesized by these three color, at infrared ray The image that sensor reads is white image, and therefore, common C, each color of M, Y broadly falls into non-for infrared ray sensor The printed material of the property distinguished.And K version color is due to carbon containing, therefore, use infrared illumination, and infrared imaging sensor is carried out During recognition, K color presents the characteristic to infrared ray absorbing with this understanding, and the image read at infrared ray sensor is black Image, therefore, with the image of K color printing, can clearly distinguish out, fixes and means under infrared ray sensor as knowing The ink of the property read.

Camouflage color dot matrix, is mainly used in fascination machine, makes optical pickup device can not read New Two Dimensional bar code.Camouflage color point The size of battle array is similar with New Two Dimensional bar code as far as possible, and arrangement can consider various, can be with New Two Dimensional bar code Lattice arrangement is similar, it is also possible to be different.Can be neat arrangement, it is possible to so that random arrangement.The angle of dot matrix distribution Degree, can be consistent with the distribution angle of New Two Dimensional bar code, it is also possible to different.In a word, as long as can make the illegal person cannot employment The dot matrix of New Two Dimensional bar code is plucked out by the method for work just may be used.

Bill images, camouflage color dot matrix, camouflage color labelling, because being non-personalized data, therefore can be reinstated with bill images one Common offset press, relief printing plate or intaglio press print, and New Two Dimensional bar code high velocity spray ink recorder prints.Certainly, exist When printing without customized information, New Two Dimensional bar code also can be printed with common offset press, relief printing plate or intaglio press. Camouflage color dot matrix can be a lot, and overlap with New Two Dimensional bar code dot matrix, it is also possible to be arranged in the sky of New Two Dimensional bar code dot matrix In gap.

Camouflage color labelling is primarily used to fascination human eye, makes human eye be not readily apparent New Two Dimensional bar code, therefore, it can importing and regard Vision model, can be that hanging point single color printing does not becomes a pattern, it is also possible to being to become a pattern with lattice arrangement, surface can be Dull color, it is also possible to be camouflage color shape pattern, it is also possible to be made up of several patterns.

New Two Dimensional bar code can be individually present, it is also possible to collectively constitutes one novel two with camouflage color dot matrix or camouflage color labelling Dimension bar code, say, that camouflage color dot matrix or camouflage color labelling can become an ingredient of New Two Dimensional bar code.

Figure 15 is the schematic diagram with the bill having New Two Dimensional bar code of 600dpi press printing.Printing at 600dpi Under precision, the New Two Dimensional bar code printed out, the size of each index point is about 0.042mm, according to Ruili criterion, human eye Visible a size of below 0.1mm, as shown in the figure: new with invoice number identical information of printing on SCURITY mark Type two-dimensional bar code is difficult to be identified by naked eyes, add New Two Dimensional bar code be printed on by CMY trichroism form there is black On the SCURITY mark of component, as it has been described above, i.e. use the most high-precision scanner to be not easy to copy New Two Dimensional bar code. Therefore can play, on the basis of a mark one yard, there is again the most reproducible antifalse effect.

Figure 16 is the schematic diagram with the bill having New Two Dimensional bar code of 200dpi press printing.Printing at 200dpi Under precision, the New Two Dimensional bar code printed out, the size of each index point is at least about 0.13mm, according to Ruili criterion people Visible a size of below the 0.1mm of eye, as shown in the figure: new with invoice number identical information brushed on SCURITY mark Although type two-dimensional bar code can may be seen indistinctly, but, due to New Two Dimensional bar code be printed on by CMY trichroism form have black The SCURITY mark of colouring component, as it has been described above, i.e. use photocopier or the most high-precision scanner still can not copy completely New Two Dimensional bar code.Can play equally, on the basis of a mark one yard, there is again the most reproducible antifalse effect.

Bill is printed with bill identification information, beats installation New Two Dimensional screen bar code recognizer on invoice machinery at machine, so that it may The bill identification system of invoice machinery beaten by composition machine, can take precautions against illegal person's false tickets and really play the phenomenon generation reaped staggering profits.

Figure 17 is in the space of New Two Dimensional bar code dot matrix, inserts the schematic diagram of camouflage color dot matrix.As shown in figure 17: 1701 Describe an information recording unit of module for information, 1702 describe an information lattice point of module for information, and 1703 is camouflage color One point of dot matrix.As above giving an account of as continuing, information describes the ink printing of the information dot matrix employing property distinguished of module, fan Color dot matrix uses the ink printing of the non-property distinguished, thus while add camouflage color dot matrix, recognizer still can be correct Identification.But, if with common scanner, the information dot matrix of invisible-bar-number and camouflage color dot matrix are all read as a kind of color Getting, scanner cannot tell any dot matrix, if carrying out manpower intervention, scratching picture by artificial method, which is not known yet One information dot matrix describing module for information, which is camouflage color dot matrix, and this is just served and prevents from being scratched by high accuracy scanning The purpose that the method for picture is forged.

Figure 18 is the schematic diagram of the two-dimensional bar code of several stacked form of current international popular.

As shown in figure 18: as the two-dimensional bar code of world's invention stacked form the earliest in 1987 by the U.S. Intermec corp invention stacked form two-dimensional bar code i.e.: Code49.Although the structure of this type code only One extension of dimension bar code, the most higher technology content, but owing to having novelty at that time, therefore become international mark Standard, uses till today in the world.

Figure 19 is the schematic diagram of several matrix form two-dimensional bar codes of current international popular.

As shown in figure 19: the two-dimensional bar code as world's invention matrix form the earliest is by Veritec company in nineteen eighty-two Invention matrix form two-dimensional bar code i.e.: VeriCode.The two-dimensional bar code of matrix form is than the two-dimensional strip of above-mentioned stacked form Code more has technology content, also because having novelty at that time, therefore becomes international standard, the most widely used.

Figure 20 is the schematic diagram that ordinary two dimensional bar code also can add camouflage color dot matrix.As shown in figure 20: 2001 is common two Dimension bar code, 2002 is an information flag of common two-dimensional bar code, and 2003 is to the addition of camouflage color in common two-dimensional bar code Dot matrix, here, camouflage color dot matrix is added in the space of two-dimensional barcode information labelling.As above-mentioned, common two-dimensional bar code Information flag use the ink printing of the property distinguished, camouflage color dot matrix uses the ink printing of the non-property distinguished, though therefore So adding camouflage color dot matrix, recognizer still can generation of accurate identification two-dimensional bar code under ultrared lighting condition Code value.But, if with common scanner, the information flag of two-dimensional bar code and camouflage color dot matrix are all read as a kind of color Arriving, scanner cannot tell any dot matrix, if carrying out manpower intervention, scratching picture by artificial method, which is not known yet The individual information flag for two-dimensional bar code, which is camouflage color dot matrix, may also function as the purpose preventing forging equally.But, two Dimension bar code is not the most that information imbeds code, and, the information characteristics spot size of two-dimensional bar code is very big, is difficult to hide, and this may It it is its congenital defect.Add the read write line can bought on market and do not support to add the knowledge of the two-dimensional bar code of camouflage color dot matrix Read, be therefore subject to certain restrictions on universal.

Figure 21 is the composition schematic diagram with read method of the New Two Dimensional bar code in the case of two kinds of different spectrum.Such as figure Shown in 21: in a New Two Dimensional bar code, can be made up of information record dot matrix 2101 and benchmark dot matrix 2102, information note can be set Record dot matrix 2101 in the case of a certain spectrum for having the property distinguished, owing to benchmark dot matrix 2102 is in the case of another kind of spectrum For having the property distinguished, they present orthogonality, i.e. information record dot matrix 2101 can be known for having in the case of a certain spectrum The property read, and have in the case of another kind of spectrum can not the property distinguished.In like manner, 2102 can know for having in the case of another kind of spectrum The property read, and have in the case of former spectrum can not the property distinguished.They also can present semi-orthogonal, i.e. at information record dot matrix Between 2101 and benchmark dot matrix 2102, a side is had to meet above-mentioned orthogonality.Such a considers to be primarily used to prevent illegal person Utilize the optical image sensor cracking code of a certain spectrum because, print New Two Dimensional bar code two parts time, be In one image, point version goes out, and therefore the position relationship between information record dot matrix 2101 and benchmark dot matrix 2102 is will not be because dividing It is that two versions are destroyed, and the image of two different spectrum can only be read out when forging by illegal person respectively, inevitable The position relationship between information record dot matrix 2101 and benchmark dot matrix 2102 can be destroyed.

AES is used for the information record dot matrix of above-mentioned New Two Dimensional bar code, benchmark dot matrix and camouflage color dot matrix, By their position, order and numerical value are encrypted, and obtain the printing image of a random distribution.In like manner, deciphering is used to calculate Method is by their position, and order and numerical value are decrypted, and obtain the printing image of original New Two Dimensional bar code.This process Purpose, scratched as replicating New Two Dimensional bar code by artificial also for preventing illegal person.

The information of the quantity dot matrix such as Figure 22 is distribution describes the schematic diagram of principle.This is also to constitute letter by the combination of dot matrix Breath describes the example of the dot matrix distribution of module, is also the geometric distribution being described many bit informations by diverse location simultaneously, Also it is the physical distribution being described many bit informations by phase-modulation.
