Description

A kind of constructive method of New Two Dimensional bar code

Technical field

The invention belongs to field of information processing, especially a kind of constructive method of New Two Dimensional bar code.

Background technology

Along with the fast development of China's economy, it is false proof that the applicating and exploitation of barcode technology is subject to tax reciept, the concern in each bar field such as commodity counterfeit prevention.

Bar code is the postgraduate's invention of managing subject of the Ha Fu university by the U.S. the earliest, and conception originally is; Client selects own needed commodity by inventory, will take the delivery of cargo window with the corresponding card of getting with punched-card machine of these commodity, just can obtain required commodity.This card correction tank farm stock can be passed through in the shop, or as request slip from expense to client that ask for.As such advanced person's logistics means, but do not popularized because of the too cheap of labour at that time.Nowadays each supermarket in the whole world, on the commodity that display in the shop, bar code is ubiquitous.Bar code has occupied very large area because of the lines of each recorded information outwardly, therefore than being easier to recognition, in fact just because the area that this bar code occupies is larger, not only affect the attractive in appearance of commodity packaging, and, owing to needing more special optical system, it therefore also is the root that the recognizer cost is difficult to reduction.

Enter the later stage of the eighties, because jewel, semiconductor, the specific (special) requirements of medicine and machinery industry, need to realize more jumbo information record at print media, particularly the application of bar code has brought huge income to enterprise, and people concentrate sight the research and development of having pointed to two-dimensional bar code.At this moment the motion of a series of two-dimensional bar codes is fallen over each other to come out of steamer.Exactly to Japan in 2011 still have the patent about two-dimensional bar code that is entitled as " the generation method of message code and message code " (JP 2011-134211) to be disclosed.But two-dimensional bar code commonly used is compared with a bar code technically and is not had breakthrough progress at present.Still tightly with the square representative information " 1 " of black, and with the square representative information " 0 " of white, still need special-purpose printing space, can not utilize printing images to imbed information.Particularly, two-dimensional bar code brings infringement to printing images attractive in appearance, this be make us always puzzled main cause.Reading at a distance exactly, owing to need to focus, therefore also existing reading speed slow, the problem that precision is low always.

In the later stage nineties, people begin to consider to play sound at printed matter, require to have larger information to record and narrate the exploitation of the code of ability.Japan has concentrated the Olympus whole strength to propose to be entitled as " code printing equipment and the code print media that is suitable for thereof " (Patent 8-208196) as a large amount of patented claims of representative.This motion proposes with the larger point in four summits can to carry out several two-dimensional bar code modules and to connect as reference point, therefore voice data directly can be recorded and narrated with this bar code.But this two-dimensional bar code except the size of each dot matrix is less than the ordinary two dimensional bar code, and can carry out outside the two-dimensional bar code module connects, and is little with the difference of ordinary two dimensional bar code.This code was once waited in expectation will have very large economic benefit and application prospect, but eventually because when recognition need to be carried out larger area scanning, its operability extreme difference is failed finally to realize original expected value and come to an end.

Since entering 2000, the progress of advancing by leaps and bounds has appearred in the technology of two-dimensional bar code.For a dot matrix, recorded and narrated by the information of the single bit of common bar code, developed into the information of many bits and recorded and narrated.Occupy independently the ordinary two dimensional bar code in space by needs and developed into and need not to occupy separate space, directly in printing images, imbed information.The A Nutou of Sweden (Anoto) company has applied for being entitled as the patent (special table 2003-511761) of " being applicable to optically read symbolism paper " in this field, this patent has proposed a dot matrix is placed on four positions of imaginary centres, can represent four information, this is the blank that many bit informations are recorded and narrated.But this patent only is limited in this narrow scope of imaginary centres, and only consider to record and narrate the coordinate figure of the two-dimensional space of paper medium, and record that can not code information.Dagger-axe Reed (Grid) company of Japan has proposed again to be entitled as " based on the data inputting method of dot pattern " (W2004/084125) under the inspiration of this patent.This patent proposes to lay four benchmark dot matrix on four summits of given one little rectangle, take these four formed imaginary centres of benchmark dot matrix as benchmark, an information dot matrix is placed on eight positions of imaginary centres, can represent eight information.This company was thinking at that time that using these four summits was cores of invention, therefore with the name of company with this word of summit (Grid), yet this motion is limited to by in four these narrow scopes of the formed imaginary centres of apex reference point battle array.An information dot matrix is wanted corresponding four apex reference point battle arrays in fact, records and narrates inadequate science on the efficient in information, that is to say that four apex reference point battle arrays might not have the meaning of existence.

The half-tone screen code patent is take " can note down in a large number the half-tone screen code control method of data " as topic (CN1598873) on paper in the meantime, except for printing net-point, in the situation of the gray scale system that does not change the site, by changing the difformity of site, diverse location, different directions, centralization and decentralization etc. can be recorded and narrated many bit informations.This patent provides comprehensive theory and method for imbed information at printed medium.The phenomenon recorded and narrated of the information that proposes of the A Nutou of above-mentioned Sweden (Anoto) company for example, in fact can be interpreted as providing a same color, the dot matrix of formed objects, be arranged in a shading according to same intervals, in the situation of the size that does not change dot matrix, by changing the position of dot matrix, just can record and narrate many bit informations.Utilize the diverse location record information of dot matrix to obtain such concern why, just because it can realize maximum information recording/by minimum dot matrix, therefore the shading that has like this information has been considered again the screen characteristic simultaneously, its result after overlapping with printing images, impact on printing images can be accomplished minimum, that is to say that such dot matrix way is suitable for imbedding for the information of printing images.

The theoretical foundation of half-tone screen code after realizing imbedding information in printing images, does not affect the effect of picture quality exactly by utilizing the screen characteristic.But, in low precision is printed, the for example printing of the following precision of 200dpi, each dot matrix has surpassed the not visible size of naked eyes that the Ruili criterion is calculated, in this case, can not be by the screen characteristic, how to realize that information attractive in appearance imbeds effect? can how when information is imbedded, realize antifalse effect again? this will be present patent application problem to be solved.

In addition, in order to consist of the standard dot pattern, as shown in Figure 5, the point 501 high H that concentrate site a ₅₀As the diameter value of two printing points (the minimum printable size of printer), the width W of the point 501 of concentrating site a ₅₀Diameter value as a printing points.The point 502 of dispersion site b only plays the effect of shading gray scale homogenization, is not used in identification, the height H of the point 502 that disperses the site ₅₁With width W ₅₁All as the diameter value of a printing points.The height of site is H ₅₂, width is W ₅₂

As shown in Figure 5, can regard concentrated site a as amplitude modulation mode i.e. (AM) screen, disperseing site b to regard i.e. (FM) screen of mode of frequency regulation as.Namely can come recorded information according to the different dot pattern of modulation system.

In addition, count the site, disperse site b to regard high-frequency as to count the site because can regard concentrated site a as low frequency, so can say that concentrating site a is according to the composition recorded information of different frequency number with disperseing site b.

And then, concentrate the gray-scale value of each site of site a large, disperse the gray-scale value of each site of site b little, so can say that also concentrating site a and disperseing site b is the recorded information of coming for the different gray-scale values of a point.

In other words, the size of the point of concentrated site a is large, and the size of each point of dispersion site b is little, so can say that concentrating site a and disperseing site b is that the dot pattern that basis varies in size comes recorded information.

About above content, a lot of interpretation procedure can also be arranged.If but identical with above dot pattern all belongs within the scope of the present invention.

Fig. 6 is the schematic diagram of being realized the many bit information records of computing machine by the information dot matrix according to the result of different positions and phase-modulation.As shown in Figure 6: figure (a) can represent information 0, and figure (b) can represent information 1, and figure (c) can represent that information 2 and figure (d) can represent information 3, and figure (e) and figure f can represent positioning datum information.

In addition, Fig. 7 is the dot matrix 701 that a given information shown in Figure 6 is recorded and narrated module, (a that the some transmitting signal of the different physical phase-modulation (PM) by information dot matrix 702 consists of, b, c) and (d) result's of four kinds of outs of phase modulation (PM) schematic diagram.

The derivation of the mathematical model of Fig. 6 and the dot pattern that is made of phase-modulation shown in Figure 7 is as follows.

If the function of the dot pattern that is made of the square lattice of interval T is ζ (x, y), then the result of ζ (x, y) after by standardization is as follows:

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

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

η(x-i×T，y-j×T)＝η(m×T，n×T)

By level of standardization m, and the centre coordinate value of the point of vertical n dot pattern is (m * T, n * T), in addition each of dot pattern put relative centre coordinate (m * T, the displacement function of n * T) is [ε (m, n), δ (m, n)], so, 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}

Namely

{[m×T+ε(m，n)×T]，[n×T+δ(m，n)×T]}∈D

Thus, input is replied function η { [i+ ε (m, n)] * T, the phase-shifted amount ζ after [j+ δ (m, n)] * T} brings into signal _{M-i, n-j}Output signal be:

$\mathrm{\ψm},n=\underset{i=-\∞}{\overset{\∞}{\mathrm{\Σ}}}\underset{j=-\∞}{\overset{\∞}{\mathrm{\Σ}}}{\mathrm{\ζ}}_{m-i,n-j}\×\mathrm{\η}\left\{\right[i+\mathrm{\ϵ}(m,n)]\×T,[j+\mathrm{\δ}(m,n)]\×T\}$

Here, control ε (m, n) and (m, n) just can realize for transmitting signal { ζ m, the phase-modulation of n}.

Information shown in Figure 6 is recorded and narrated the dot matrix of module and is arranged a combined result still can regarding as in the full combination of dot matrix, the i.e. combination of dot matrix.

Fig. 8 is one and is distributed by the diverse location of information dot matrix and the schematic diagram of the many bit informations of phase-modulation outcome record.As shown in Figure 8: 800 are information record module image.801,802,803 and 804 is the information dot matrix, and each point is according to the numerical value 0 to 3 that can represent shown in Figure 6, i.e. 2 bit informations, and four points just can represent numerical value 0 to 255, i.e. 8 bit informations.Each point can also represent numerical value 0 to 7, i.e. 3 bit informations, and four points just can represent numerical value 0 to 4096, i.e. 12 bit informations.805,806 is horizontal direction positioning datum dot matrix, be mainly used in the positioning datum in the horizontal direction as information dot matrix 801-804, or the horizontal direction initial value of phase-modulation, 808,809 is vertical direction positioning datum dot matrix, is mainly used in the positioning datum in the vertical direction as information dot matrix 801-804, or the vertical direction initial value of phase-modulation.

Information shown in Figure 8 is recorded and narrated the information recording method of module, can also regard as by information dot matrix relative level to be decided to be dot matrix, and the diverse location of perpendicular positioning dot matrix distributes to record many bit informations.Information shown in Figure 8 is recorded and narrated the dot matrix of module and is arranged a combined result can regarding as in the full combination of dot matrix, the i.e. combination of dot matrix.

It not only can be the 1*1 dot matrix that information is recorded and narrated the arrangement of module character library dot matrix, the 1*2 dot matrix, the 3*3 dot matrix can also be 3*4, or 4*4 dot matrix, or 4*5, or the 5*5 dot matrix, or the 5*6 dot matrix, or 6*6 dot matrix, or the n*n dot matrix, so long as the geometric or physical dot matrix that the present invention proposes is arranged, the character library that makes all belongs within the interest field of the present invention.

Fig. 9 is the dot matrix distribution schematic diagram of recording and narrating module by the information that constitutes of dot matrix.As shown in Figure 9: another means that realize the New Two Dimensional bar code, in the set that the dot matrix of common two-dimensional bar code distributes, to find out one group to have the code that comprises the printing net screen characteristics and distribute, or dot matrix distributes relatively uniform, or hamming is the similar degree minimum apart from maximum between code, or the combined result of other purposes, or according to the recognition characteristics of fixed focal length, the lattice dimensions of code is dwindled, consist of a New Two Dimensional bar code.

Fig. 9 is the example that the information of 20*20 dot matrix is recorded and narrated the dot matrix module, and 900 is the information record dot matrix module of 20*20 dot matrix among the figure, and a little 901 expression information dot matrix " 1 " are arranged, and does not have point 902 expression information " 0 ", dot matrix 903 expression positioning datum dot matrix on every side.As shown in Figure 9, in the set that the dot matrix of common two-dimensional bar code distributes, according to the printing net screen characteristics, find out distribution uniform, a kind of combination that dot matrix is separated from each other distributes, and for example in each group 6*6 dot matrix of common two-dimensional bar code, the 3*3 dot matrix that is separated from each other by each group consists of New Two Dimensional bar code shown in Figure 9, the information of the byte of some matrix representation of each 3*3, can find out, compare with the ordinary two dimensional bar code, each dot matrix is separated from each other, dot matrix distributes more even, although compare with above-mentioned New Two Dimensional bar code, some irregular distributions are arranged, because larger than the quantity of information of above-mentioned information record module record, therefore, certain Practical significance is arranged.

In addition, according to the needs of using, for example increase the hamming distance between the code for the ordinary two dimensional bar code, reduce the similar degree between code, improve the code distributing homogeneity, the maximization of code distribution area, minimizing etc. of code distribution area can realize various dot matrix combinations, form various code forms, simultaneously, can generate the character library of various dot pattern, these all belong within the scope of the present invention.

Figure 10 is the another kind of dot matrix distribution schematic diagram of recording and narrating module by the information that constitutes of dot matrix.As shown in figure 10: 1001 expression perpendicular positioning dot matrix, the interval of 1002 expression perpendicular positioning dot matrix, 1003 expression horizontal location dot matrix, the interval of 1004 expression horizontal location dot matrix, 1005 expression information dot matrix.

Approximate with the ordinary two dimensional bar code, here utilize all residential quarters in the shared zone of New Two Dimensional bar code, but the information of a bit is recorded and narrated in the dot matrix zone that namely has capacity of decomposition, information in each residential quarter " 1 " can represent with the B﹠W of bianry image with information " 0 ", also can represent with the difference of the gray-scale value of coloured image integral body, also can represent with different colors, also can be with in the bitmap of coloured image less on image impact, obvious low level immediately distributes, rule and the information content according to Figure 10 are replaced, in a word, information in each residential quarter " 1 " needs only under the condition that guarantees capacity of decomposition with information " 0 ", records and narrates by difference realization information.

Figure 11 utilizes color region that RGB color space and CMYK color space can not conversion to realize the schematic diagram of anti-counterfeit printing.The general employed color space of scanner is the RGB form, and the employed color space of common printed machine is the CMYK form.As shown in figure 11: if color is chosen in the color region of RGB/CMYK, its printed image that goes out can be scanned instrument and copy faithfully and print out, and namely this color region is reproducible zone.Again as shown in figure 11: copy faithfully if select the printed image that goes out of RGB color region or CMYK color region can not be scanned instrument.Utilize such principle can realize the effect of anti-counterfeit printing.For example, the color of New Two Dimensional bar code is selected the K version, on the New Two Dimensional bar code, can print the image that becomes with CMY three colour cells, and for example the color of image of fruit CMY three colour cells one-tenth is darker, actual composition with black, but owing to not containing carbon in the color of image with CMY three colour cells one-tenth, be transmission to infrared ray, therefore do not affect the recognition of the New Two Dimensional bar code of K version.But, if above-mentioned image is scanned instrument and copies, the printed image that goes out, the original color of image of the composition with black that becomes of CMY three colour cells, when dividing version, will be reflected on the K version, clash with the original New Two Dimensional bar code on the K version, therefore can not correctly read the New Two Dimensional bar code on the K version, thereby reach false proof effect.

Figure 12 adds camouflage color dot matrix, the schematic diagram of camouflage color mark in the New Two Dimensional bar code.As shown in figure 12: 1201 is bill images, and 1202 is the New Two Dimensional bar code, and 1203 is the camouflage color dot matrix, and 1204 is the camouflage color mark.The New Two Dimensional bar code is used the printing ink of the property distinguished, ink powder, and a kind of printed material in the ink prints, and here, the printing ink of the property distinguished refers to; Use readable printed material to implement printing at print media, the image after its printing under the long illumination of institute's standing wave and corresponding imageing sensor, can read by imageing sensor.Camouflage color dot matrix and camouflage color mark use the printing ink of the non-property distinguished, ink powder, and a kind of printed material in the ink prints, and here, the printing ink of the non-property distinguished refers to; Use non-readable printed material to implement printing at print media, the image after its printing under the long illumination of institute's standing wave and corresponding imageing sensor, can not read by imageing sensor.For example: adopt infrared illumination, and infrared imaging sensor is when distinguishing, with this understanding, and common C, M, therefore no matter all present transparently after each color of Y is reflective by blank sheet of paper, by the synthetic random color of these three kinds of colors, the image that reads at infrared ray sensor is white image, therefore, common C, M, each color of Y all belongs to the printed material of the non-property distinguished for infrared ray sensor.And K version color is because carbon containing, therefore, adopt infrared illumination, and infrared imaging sensor is when distinguishing, and the K Color expression is to the characteristic of infrared ray absorbing with this understanding, and the image that reads at infrared ray sensor is black image, therefore, with the image of K color printing, can clearly distinguish out, fixedly mean under infrared ray sensor, to be the printing ink of the property distinguished.

The camouflage color dot matrix is mainly used in confusing machine, makes optical pickup device can not read the New Two Dimensional bar code.The size of camouflage color dot matrix is similar with the New Two Dimensional bar code as far as possible, and arrangement can be considered various, can with the dot matrix homotaxy of New Two Dimensional bar code, also can be different.Can be neat arrangement, also can make random arrangement.The angle that dot matrix distributes can be consistent with the distribution angle of New Two Dimensional bar code, also can be different.In a word, so long as illegal person can't be plucked out the dot matrix of New Two Dimensional bar code with artificial method just can.

Bill images, therefore camouflage color dot matrix, camouflage color mark can reinstate common offset press with bill images one because be non-personalized data, and relief printing plate or intaglio press print, and the New Two Dimensional bar code is printed with the high speed ink jet numbering machine.Certainly, when need not the customized information printing, the New Two Dimensional bar code is available common offset press also, and relief printing plate or intaglio press print.The camouflage color dot matrix can be a lot, and overlap with New Two Dimensional bar code dot matrix, also can be arranged in the space of New Two Dimensional bar code dot matrix.

The camouflage color mark mainly is to confuse human eye, make human eye be difficult for seeing the New Two Dimensional bar code, therefore, can import vision mode, can be that the hanging point single color printing does not become a pattern, also can be to be arranged in a pattern with dot matrix, and the surface can be dull color, also can be camouflage color shape pattern, also can be formed by several patterns.

The New Two Dimensional bar code can independently exist, and also can that is to say with camouflage color dot matrix or New Two Dimensional bar code of the common composition of camouflage color mark, and camouflage color dot matrix or camouflage color mark can become an ingredient of New Two Dimensional bar code.

Figure 13 is the schematic diagram with the bill that the New Two Dimensional bar code is arranged of 600dpi press printing.Under the printing precision of 600dpi, the New Two Dimensional bar code that prints out, each monumented point is of a size of about 0.042mm, according to the Ruili criterion, human eye can be seen and be of a size of below the 0.1mm, as shown in the figure: printing is difficult for being identified by naked eyes with the New Two Dimensional bar code of invoice number identical information on the SCURITY sign, adding the New Two Dimensional bar code is on the SCURITY sign with black component that is printed on to be become by CMY three colour cells, as mentioned above, namely use very high-precision scanner also to be difficult for copying the New Two Dimensional bar code.Therefore can play on the basis of one yard of a mark and have again not reproducible antifalse effect.

Figure 14 is the schematic diagram with the bill that the New Two Dimensional bar code is arranged of 200dpi press printing.Under the printing precision of 200dpi, the New Two Dimensional bar code that prints out, the size of each monumented point is at least about 0.13mm, can see according to Ruili criterion human eye and to be of a size of below the 0.1mm, as shown in the figure: although the New Two Dimensional bar code with the invoice number identical information of printing can be may be seen indistinctly on the SCURITY sign, but, because the New Two Dimensional bar code is the SCURITY sign with black component that is printed on to be become by CMY three colour cells, as mentioned above, namely use duplicating machine or very high-precision scanner still can not copy the New Two Dimensional bar code fully.Can play equally on the basis of one yard of a mark and have again not reproducible antifalse effect.

Be printed with bill identification information at bill, make Installation of New Type two-dimensional bar code recognizer on the invoice machinery at machine, just can the formation machine beat the bill identification system of invoice machinery, can take precautions against illegal person's false tickets and very play to get the phenomenon generation of reaping staggering profits.

Figure 15 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 15: 1501 information recording units for information record module, 1502 information lattice points for information record module, 1503 is a point of camouflage color dot matrix.As above give an account of continue such, information is recorded and narrated the ink printing of the information dot matrix employing property distinguished of module, and the camouflage color dot matrix adopts the ink printing of the non-property distinguished, although therefore added the camouflage color dot matrix, recognizer still can accurately be identified.But, if with common scanner, the information dot matrix of invisible-bar-number and camouflage color dot matrix all are used as a kind of color and have read, scanner can't be told any dot matrix, if the implementation manpower intervention is scratched picture with artificial method, do not know which is the information dot matrix that information is recorded and narrated module yet, which is the camouflage color dot matrix, and this has just played the purpose that prevents from scratching by high precision scanning the method forgery of picture.

Figure 16 is the schematic diagram that the ordinary two dimensional bar code also can add the camouflage color dot matrix.As shown in figure 16: 1601 is common two-dimensional bar code, and 1602 is an information flag of common two-dimensional bar code, and 1603 for to have added the camouflage color dot matrix in common two-dimensional bar code, and here, the camouflage color dot matrix is added in the space of two-dimensional barcode information mark.With above-mentioned, the ink printing of the property distinguished is adopted in an information flag of common two-dimensional bar code, the camouflage color dot matrix adopts the ink printing of the non-property distinguished, therefore although added the camouflage color dot matrix, the code value that recognizer still can accurate identification two-dimensional bar code under ultrared lighting condition.But, if with common scanner, the information flag of two-dimensional bar code and camouflage color dot matrix all are used as a kind of color and have read, scanner can't be told any dot matrix, if the implementation manpower intervention is scratched picture with artificial method, do not know which is the information flag of two-dimensional bar code yet, which is the camouflage color dot matrix, equally also can play to prevent the purpose of forging.But two-dimensional bar code is not that information is imbedded code eventually, and the information characteristics spot size of two-dimensional bar code is very large, is difficult for hiding, and this may be its inadequate natural endowment.Add the read write line that to have bought on the market and do not support to add the recognition of the two-dimensional bar code of camouflage color dot matrix, therefore be subject to certain restrictions popularizing.

Figure 17 is the formation of the New Two Dimensional bar code in two kinds of different spectrum situations and the schematic diagram of read method.As shown in figure 17: in a New Two Dimensional bar code, can be formed by information recording/dot matrix 1701 and benchmark dot matrix 1702, can establish information recording/dot matrix 1701 in a certain spectrum situation for having the property of recognition, since benchmark dot matrix 1702 in another kind of spectrum situation for having the property of recognition, they present orthogonality, be information recording/dot matrix 1701 in a certain spectrum situation for having the property of recognition, can not the property distinguished and in another kind of spectrum situation, have.In like manner, 1702 in another kind of spectrum situation for having the property of recognition, can not the property distinguished and in front a kind of spectrum situation, have.They also can present semi-orthogonal, namely between information recording/dot matrix 1701 and benchmark dot matrix 1702, have a side to satisfy above-mentioned orthogonality.A kind ofly like this consider it mainly is to prevent that illegal person from utilizing the optical image sensor of a certain spectrum to crack code, because, when two parts of printing New Two Dimensional bar code, a minute version goes out in an image, therefore the position relationship between information recording/dot matrix 1701 and the benchmark dot matrix 1702 is can be not destroyed because being divided into two versions, and illegal person can only be respectively when forging reads the image of two different spectrum, will inevitably destroy the position relationship between information recording/dot matrix 1701 and the benchmark dot matrix 1702.

For the information recording/dot matrix of above-mentioned New Two Dimensional bar code, benchmark dot matrix and camouflage color dot matrix use cryptographic algorithm, and with their position, order and numerical value are encrypted, and obtain the printing images of a stochastic distribution.In like manner, use decipherment algorithm with their position, order and numerical value are decrypted, and obtain the printing images of original New Two Dimensional bar code.The purpose of this processing also is in order to prevent that illegal person from copying the New Two Dimensional bar code by the artificial picture of scratching.

Figure 18 is the schematic diagram that the bill customized information is all represented with the New Two Dimensional bar code.As shown in figure 18: purchasing unit, Description of Goods, quantity, price, the amount of tax to be paid, the information such as sales unit at password area, are imbedded with the New Two Dimensional bar code information of carrying out fully.Owing to being to adopt stylus printer to print, although printing precision is very low, still can the acquired information amount, arrange reasonable effect attractive in appearance.

The information that the quantity dot matrix such as Figure 19 is distribute is recorded and narrated the schematic diagram of principle.This also is the example of recording and narrating the dot matrix distribution of module by the information that constitutes of dot matrix, also is the geometric distribution of recording and narrating many bit informations by diverse location simultaneously, also is the physical distribution of recording and narrating many bit informations by phase-modulation.

As shown in figure 19: but utilize four dot matrix zones with capacity of decomposition can record and narrate the information of 2 bits by a dot matrix, lack one times although record and narrate the record quantity of information of module than the information of Figure 10, because no matter how many values of information is, the quantity that information is recorded and narrated the module dot matrix is constant, therefore see on the whole, the stochastic distribution of code is less, but the aesthetic property of the density that acquired information is recorded and narrated and the code effect of compatibility mutually.For example (a) can represent information " 0 " among the figure, (b) can represent information " 1 ", (c) can represent information " 2 ", (d) can represent information " 3 ".

Figure 20 is that the information that the quantity dot matrix such as employing consists of is recorded and narrated the module schematic diagram.As shown in figure 20: 2001 expression perpendicular positioning dot matrix, the interval of 2002 expression perpendicular positioning dot matrix, 2003 expression horizontal location dot matrix, the interval of 2004 expression horizontal location dot matrix, the residential quarter of 2005 expression 2*2,2006 are illustrated in an information dot matrix in the residential quarter of 2*2.Four diverse locations of each information dot matrix in the residential quarter of fixed 2*2 represent respectively different information.

Figure 21 is the form of expression schematic diagram of the bitmap of coloured image.As shown in figure 21: the image of 256 gray scales of any one expression is by the coded representation of 8 bits, can consist of the image of each bit, and the profile of original image can be seen in the higher bit position, and the lower image of figure place is fuzzyyer, and image more presents stochastic distribution.That is to say that the lower impact on original image of figure place is less, utilize this characteristic, above-mentioned New Two Dimensional bar code and a minimum bitmap can be replaced, or replace with several minimum bitmaps, then printout just can obtain a printing images that is embedded with information.Here, can be at R, G imbeds information in a kind of color of B, also can imbed simultaneously information in two or three color.

Figure 22 is the schematic diagram with the New Two Dimensional bar code of written form formation.As shown in figure 22: in literal " is complied with ", have 12 information to record and narrate module, the information of the 2201st, 7*9 dot matrix is recorded and narrated module, 2202 also is the information record module of 7*9 dot matrix, the information of the 2203rd, 7*17 dot matrix is recorded and narrated module, the information of the 2204th, 7*7 dot matrix is recorded and narrated module, the information of the 2205th, 9*11 dot matrix is recorded and narrated module, the information of the 2206th, 9*7 dot matrix is recorded and narrated module, the information of the 2207th, 9*7 dot matrix is recorded and narrated module, the information of the 2208th, 5*7 dot matrix is recorded and narrated module, and the information of the 2209th, 7*7 dot matrix is recorded and narrated module, and the information of the 2210th, 11*7 dot matrix is recorded and narrated module, the information of the 2211st, 9*7 dot matrix is recorded and narrated module, and the information of the 2212nd, 11*9 dot matrix is recorded and narrated module.

Here, during principle that information is imbedded, the literal outline will keep the original shape of literal that the phenomenon of broken string is not arranged as far as possible, and is as far as possible smooth, runs into the span that two points are arranged in the situation near the curves of 45 degree, should mend a point.Need not mend a little during near straight line, in a word the literal smooth and beautiful appearance of should trying one's best.Benchmark dot matrix " 1 " is greater than 1 grid with the interval of other dot matrix, and benchmark dot matrix " 0 " is greater than 2 grids with the interval of other dot matrix, and the interval of information dot matrix and other dot matrix is greater than 2 grids.

Around each group information record module certain interval to be arranged, cut apart in order to carry out program.The quantity of information of the information of imbedding in literal is large as far as possible, and the total area that the information that can lay is recorded and narrated module is large as far as possible.

Figure 23 is the application schematic diagram with the New Two Dimensional bar code of the form of literal.As shown in figure 23: in using the stylus printer tax reciept, the content that tax reciept is printed can be imbedded with " paying tax in accordance with the law " four literal information of carrying out, both can solve because the stylus printer tax reciept uses common two-dimensional bar code to affect nominal value problem attractive in appearance, the tax reciept print What all can be embedded in the New Two Dimensional bar code again.

Figure 24 is the application schematic diagram with the New Two Dimensional bar code of lace pattern form.As shown in figure 24: in using the stylus printer tax reciept, the content that tax reciept is printed can be imbedded with the form information of carrying out of lace, both can solve because the stylus printer tax reciept uses common two-dimensional bar code to affect nominal value problem attractive in appearance, the tax reciept print What all can be embedded in the New Two Dimensional bar code again.

Figure 25 is the application schematic diagram with the New Two Dimensional bar code of shading form.As shown in figure 25: in using the stylus printer tax reciept, the content that tax reciept is printed can be imbedded with the form information of carrying out of full version shading, can solve because the stylus printer tax reciept uses common two-dimensional bar code to affect nominal value problem attractive in appearance, the tax reciept print What all can be embedded in the New Two Dimensional bar code again.

Figure 26 uses the laser beam marking machine to realize yard schematic diagram of paying of New Two Dimensional bar code.As shown in figure 26: use the laser beam marking machine directly on production line, to carry out authentication for commodity, can accomplish the unification of commodity and packing, merchandise control and commodity counterfeit prevention, the unification of commodity inspection.

Figure 27 is the schematic diagram of imbedding information with the New Two Dimensional bar code in normal image.As shown in figure 27: utilize the human eye visual characteristic lower to the recognition capability of gradation of image, adopt the overall gray difference of image, namely change the gray-scale value of image according to the dot matrix state of New Two Dimensional bar code, or only namely on the bitmap at low level the New Two Dimensional bar code is replaced bitmap images in the difference of the gradation of image on the bitmap of image low level, information is embedded in the image.Here, the dot matrix of recording and narrating module as the information of imbedding information in normal image distributes, and can be such as Figure 10, Figure 20, the distribution of any one dot matrix combination that Fig. 9 is such also can be such as Fig. 3, Fig. 4, Fig. 5, the geometric distribution that Fig. 8 is such or physical distribution.

Figure 28 is that the New Two Dimensional bar code has the schematic diagram of encrypting character.As shown in figure 28: establishing P (t) is a random function, and the dot matrix that the dot matrix combination produces is:

d ₁₁，d ₁₂，…，d _1f

D＝d ₂₁，d ₂₂，…，d _2f

……

d _g1，d _g2，…，d _gf

The random alignment function of position of the battle array of setting up an office again in two-dimensional space is: ζ [p (x), p (y)], then dot matrix makes up each dot matrix d that produces _IjThe position be: ζ _Ij[p (x _Ij), p (y _Ij)].

The dot matrix d that Figure 28 if (a) produces for the dot matrix combination _IjRandom alignment ζ in two-dimensional space _Ij[p (x _Ij), p (y _Ij)], according to Fig. 6, the information of dot matrix shown in Figure 8 is recorded and narrated principle, the dot matrix d that the dot matrix combination produces _IjAt ζ _Ij[p (x _Ij), p (y _Ij)] on the position, although can represent one group of established data,, owing to there not being basis of reference, therefore can not identify this group data, only have as Figure 28 (b), add one group of benchmark dot matrix, at this moment, just can make up the dot matrix d that produces to dot matrix _IjRepresented one group of data identification determining goes out.

Particularly as the two-dimensional space of electronic image in the X coordinate axis, and can carry out unlimited division on the Y coordinate axis, the characteristic of therefore utilizing above-mentioned dot matrix to distribute can realize the data encryption effect more much higher than the security of present conventional cryptographic algorithm.

Have again, if the electronic image combination of same reality can also accomplish both can obtain the encryption of high security, can realize again the encryption of the hidden greater security of data simultaneously.
