Embodiment

Below, imbed method with reference to accompanying drawing to a kind of information being suitable for mobile phone masses recognition printing images of the present invention, the embodiment of printing images information identifying method is described.

Fig. 1 is the process flow diagram that the popular information distinguishing product identification of mobile phone imbeds method.As shown in Figure 1: a kind of information being suitable for mobile phone masses recognition product identification imbeds method, and be by data reading step, information imbeds step, and printing images exports step composition, and concrete steps are as follows:

Data reading step: read the data that will imbed from storer, and will the object images imbedded of the information of carrying out.The data that will imbed comprise anti-counterfeiting codes data, product back-tracing data, commodity ID, and for the commercial product code of commodity clearing, the country of commodity production and Enterprise organization system code, one yard of information etc. marked by commodity one.

Here object images refers to the image that the above-mentioned data imbedded will be imbedded, such as commodity sign image, commodity packaging image and other printing images etc.

Information imbeds step: the position of setting reference point, according to the position of reference point, electronic image is carried out zonule division, adopt the discrepancy adjustment method of the image state between diverse location, or dot pattern is hidden concealed code that method forms and the above-mentioned data that will imbed read is embedded in the object images that above-mentioned information imbeds.

Here information is imbedded and is realized by two methods, and first method: the image be embedded in is divided into several zonules, utilizes the image condition between adjustment two zonules, makes it form difference thus imbed information.

Here image condition refers to the gray-scale value situation of each pixel of image in this zonule, or the Quantity of the point of site, the amplitude modulation of site or frequency modulation situation, the difference of the cable angle situation of the point of site etc. or difference.

The discrepancy adjustment method of the image state between diverse location here refers to the state comprising an adjustment zonule image, or the state adjusting another zonule image makes it the method forming difference; Or adjustment territory, center cell, or the state of adjustment peripheral cell area image makes it the method forming difference; Or the state of adjustment core image in a zonule, or the method that peripheral part image state adjusted in this zonule makes it to be formed difference imbeds method in interior wherein a kind of information.

Second method: dot pattern hides method, the data will imbedded in printing images are transformed into has geometry distribution, or the possible lattice codebook of handset identity of physics distribution.Described " lattice codebook of geometry distribution ", refer to the distribution of its lattice codebook, by the having or nothing of point of its site, the two-dimensional bar code that such as common QR is such, or various forms of take code sign as stain identification information " 1 " or " 0 ", white point mark " 0 " or " 1 " code.

The different position distribution of the point of site refers to the lattice codebook recording different information with the point of site with different positions.By different position recorded informations, can by the more information of little dot matrix record, the lattice codebook of this form generally only has the area of less than 2%, can the space of 98% be left for imbed object image, therefore the structure of this code itself just has Information hiding feature, therefore can be called Information hiding code.Utilize the different many bit informations of position distribution record of the point of site, the focus of its competition, is how to make the quantity of the point of the benchmark dot matrix of code minimum, and is used for information record using more putting as information dot matrix, to improve the efficiency of information record.

Equally, utilize the different directional spreding of the point of site, the different distribution of shapes of the point of site, the different site size of the point of site, the geometric distribution modes such as the different site number distribution of the point of site and the centralization and decentralization of printing points can record many bit informations.

Described " lattice codebook of physics distribution ", refer to the distribution of its lattice codebook, by the different modulating mode of the point of its site, Modulation and Amplitude Modulation mode and the AM screen site of such as site represent information " 1 ", and frequency modulated mode FM screen site represents information " 0 " etc.

The phase modulation method of the point of site can obtain the effect of the code of the many bit informations of diverse location record of the point of above-mentioned site.Utilize the code of this form can obtain more high efficiency information record effect.

Equally, utilize the different direction of propagation of the point of site, the different frequency of the point of site, the different mechanical characteristic of the point of site, the physical distribution modes such as the different gray-scale value of the point of site can record many bit informations.

Finally dot pattern code is directly overlapped with printing images, just can reach the effect that information is imbedded, but in order to prevent the impact on printing images, the size of the point of site needs at below 0.042mm, in this case the identification difficulty of mobile phone, if the size strengthening the point of site affects again the quality of printing images.

Dot pattern code is hidden again by the present invention, thus really achieves the formation of stealthy code.

Printing images exports step, and will imbed the commodity sign image of information, the printing images such as commodity packaging image are printed by digital printer, make the printing images being embedded with variable information.

Fig. 2 is the process flow diagram of the information identifying method of mobile phone masses recognition product identification.

As shown in Figure 2: a kind of information identifying method being suitable for mobile phone masses recognition product identification is by handset image read step, stealthy code identification step, code value output step composition, concrete steps are as follows:

Handset image read step, is embedded with the commodity sign of information with the alignment lens of mobile phone, the printing images of commodity packaging etc., and reading printing images is an electrical image data;

Stealthy code identification step, according to reference point, electronic image is carried out zonule division, according to the discrepancy adjustment method of the image state between employing diverse location described later, or dot pattern hides the rule that the concealed code information of carrying out that method forms imbeds, and identifies the code value of stealthy code;

Code value exports step, according to the code value retrieval network server of the above-mentioned stealthy code identified, downloads corresponding data and is presented on mobile phone screen.

As shown in Fig. 3 (a): if information is " 1 ", the high numerical value Vc of the gray-scale value of the gray-scale value of each pixel in zonule 301 than 302 can be established, as shown in Fig. 3 (b); If information is " 0 ", the low numerical value Vc of the gray-scale value of the gray-scale value of each pixel of zonule 301 than 302 can be established.Otherwise, if information is " 1 ", also can establish the low numerical value Vc of the gray-scale value of the gray-scale value of each pixel of zonule 301 than 302, if information is " 0 ", also can establish the high numerical value Vc of the gray-scale value of the gray-scale value of each pixel of zonule 301 than 302.

Here, numerical value Vc is the degree of the 10%-20% of the highest gray-scale value, and the highest gray-scale value of general pattern is 256, therefore between the concrete desirable 25-50 of numerical value.This numerical value is too large, can the quality of effect diagram picture, too littlely can identify difficulty.

As shown in Fig. 4 (a): if information is " 1 ", the many numerical value Ve of the point of the site of point than 402 of the site of zonule 401 can be established.As shown in Fig. 3 (b): if information is " 0 ", the few numerical value Ve of the number of the point of the site of number than 402 of the point of the site of zonule 401 can be established.Otherwise, if information is " 1 ", the few numerical value Ve of the point of the site of point than 402 of the site of zonule 401 can be established.If information is " 0 ", the many numerical value Ve of the number of the point of the site of number than 402 of the point of the site of zonule 401 can be established.

When FM screen site, above-mentioned numerical value Ve is the degree of the 10%-20% of the number of the point of maximum site, and when AM screen site, above-mentioned numerical value Ve is the degree of the 10%-20% of the area of the point of maximum site.This numerical value is too large, and the quality of meeting effect diagram picture, too little being not easy identifies.

As shown in Fig. 5 (a): 501 is the zonules will imbedding information, 502 is with AM Modulation and Amplitude Modulation screen site schematic diagram, when the site of this zonule is AM Modulation and Amplitude Modulation screen site, can imbed information " 1 ", otherwise also can represent information " 0 ".As shown in Fig. 5 (b): 501 is the zonules will imbedding information, 503 is that information " 0 " can be imbedded in this zonule, otherwise also can represent information " 1 " with FM frequency modulation halftone screen site.

As shown in Fig. 6 (a): 601 is the zonules will imbedding information, 602 is site cable angles be 0 zonule schematic diagram, information " 1 " can be imbedded in this zonule, otherwise also can represent information " 0 ".As shown in Fig. 6 (b): 601 is the zonules will imbedding information, 603 is site cable angles is the zonule schematic diagram of 45 degree, and information " 0 " can be imbedded in this zonule, otherwise also can represent information " 1 ".

In order to improve the efficiency that information is imbedded, the method that the employing center reference gray-scale value information of carrying out as shown in Figure 7 is imbedded can be taked.Here using the gray-scale value of each pixel in territory, center cell 700 as benchmark gray-scale value, territory, peripheral cell 701,702,703,704,705,706, the gray-scale value of each pixel of 707 and 708 zonules, with the gray-scale value of each pixel of benchmark gray-scale value 700 zonule for benchmark, be " 1 " or " 0 " according to the information of imbedding, adjust territory, peripheral cell 701 respectively, 702,703,704,705, the gray-scale value of each pixel in 706,707 and 708 zonules and the average gray value of benchmark gray-scale value 700 zonule form difference.
