Detailed Description
The following describes the detailed implementation of the embodiments of the present invention with reference to the drawings. It should be understood that the detailed description and specific examples, while indicating and illustrating the invention, are not intended to limit the invention.
Fig. 1 is a flowchart of an anti-counterfeit method of a color partition micro-point code mark with a scalable counterfeit authentication according to an embodiment of the present invention. As shown in fig. 1, the method includes:
step S101, randomly generating a two-dimensional code value and a color distribution number corresponding to the two-dimensional code value;
and generating a random two-dimension code value which is not repeated with the two-dimension code value already generated in the database according to a random algorithm, and ensuring that each commodity marked by the two-dimension code has a unique digital identity card. In addition, color distribution numbers corresponding to the two-dimensional code values are generated according to a random algorithm, so that the color distribution numbers of each two-dimensional code value are different, the batch copying cannot be realized, and the counterfeiting difficulty is improved.
Step S102, generating a color two-dimensional code image according to the two-dimensional code value and the color distribution number, wherein the color two-dimensional code image comprises at least one color area and consists of a plurality of square two-dimensional code modules with the same side length;
based on the unique non-repeated two-dimensional code value, a black-and-white two-dimensional code image is generated according to an open source standard two-dimensional code coding algorithm and is used as a data source for printing the color two-dimensional code to be input.
The color distribution numbers are used for coloring the areas of the images of the two-dimension codes to generate the images of the color two-dimension codes, the anti-counterfeiting technology is improved by using the anti-counterfeiting labels of the color two-dimension codes, and the common printing factories cannot print the variable-color two-dimension code labels, so that the counterfeiting cost and the counterfeiting difficulty of counterfeiters are effectively increased.
The color of the image of the color two-dimensional code is preferably not less than 20 and not more than 200 in gray scale value. At the same time, the overall average gray level of all the areas with different colors is not less than 20 and not more than 200. The Gray scale of the color can be calculated according to the known formula gray=Rx0.299+Gx0.587+Bx0.114 to verify that the Gray scale of each area of one or more color partitions of the color two-dimensional code and the average Gray scale of the whole two-dimensional code are both obviously contrast compared with the printing base material, and can be distinguished from micro-point codes with the Gray scale of about 0-20, and the binarization in key links which do not affect the reading is realized when the micro-point codes are mutually overlapped. The two-dimensional code module is relatively large and can be read in a color mode by utilizing relatively small code points of the micro-point code, so that the problem that two-dimensional codes which are similar in area scale and depend on the gray level binarization principle cannot be mutually compatible is solved greatly.
The coloring area of the image of the color two-dimensional code may be one or more areas, and preferably four areas of the image of the two-dimensional code are colored according to the color distribution number. In the embodiment of the invention, the coloring is preferably performed in a CMYK mode, so that the color can be better distinguished from micro-point code points. Pure red and yellow are avoided during CMYK color selection, acquisition efficiency and experience sense are prevented from being influenced, and dark color system colors (K100, M100C100 and M100Y 100) are avoided, so that when the micro-point code and the two-dimensional code are overlapped, the recognition of the micro-point code is prevented from being influenced by the dark color.
The color two-dimensional code is colored according to the color distribution number, and preferably, the color range can be C100YN (1 < N < 33): preferably 30, just between 1 and 60; c100YM: (Nmax < M < 100): preferably 60, just between 30 and 100. The gray level can be ensured to be enough to be convenient for reading, and the consumer can conveniently distinguish light green and medium green from chromatic aberration. Preferably, C100Y100, C100Y30, C100Y60 and C100 are used for coloring four areas, so that color replacement of the two-dimensional code is finished, the color is convenient for people to read, and the color is compatible with online acquisition of an industrial vision camera.
Step S103, obtaining a micro-point code value according to a micro-point code transmitting system;
the micro-point code is a sparse dot matrix code with high robustness, and is an encoding algorithm and a decoding algorithm without open source, the code diagram can not be read by other open source code system decoding algorithms, compared with the traditional dense two-dimensional code which converts code values into binary 1 and 0 and respectively arranges the binary 1 and the binary 0 in a deep and shallow code point form, the code value of the micro-point code is converted into binary data, and a clear gap with more than or equal to 1 data position exists between the binary data and the data, and the code value can be a character string of any character codes.
The random additional point figure safety code physical identification manufactured by the micro point code supports the robustness of more than 90% in 20mm x 20mm, supports the decoding still from the pollution to the whole area of any 3mm x 3mm, still has 15% fault tolerance in the minimum readable area of 3mm x 3mm, and supports the reading still under the interference figure beyond the linear, bulk and special-shaped code points. The lattice code system meeting the robustness condition provides powerful guarantee for embedding the anti-counterfeiting characteristics with enough quantity, area and position independence.
According to the embodiment of the invention, the micro-point code value is obtained according to the micro-point code transmitting system, and the micro-point code value is unique and non-repeatable.
Step S104, determining the side length and the readable area of the micro-point code points of the universal detection area according to the side length of the two-dimensional code module, so that the micro-point code of the universal detection area does not influence the readability of the image of the two-dimensional code;
the side length of the two-dimensional code module is calculated according to a two-dimensional code disclosure algorithm (if the side length of a two-dimensional code area is 15000 micrometers and the two-dimensional code area is transversely or longitudinally arranged by 29 two-dimensional code modules, the side length of the two-dimensional code module is 15000/29 approximately 500 micrometers), and the side length and the readable area of the micro-point code points of the universal detection area satisfy the following relations:
（W²/R²）*w²＜W²/2
wherein W is the side length of the two-dimensional code module, R is the readable area of the micro-point code point of the universal detection area, and W is the side length of the micro-point code point of the universal detection area.
Through the formula, one or more groups of W and R can be calculated, and the readability of the two-dimensional code can not be affected by the micro-point code even if the micro-point code and the two-dimensional code are overlapped by using the W and the R. The side length of the two-dimensional code module is preferably 4 times of the side length of the micro-point code point.
Step S105, generating a first image of the micro-point code based on the micro-point code value according to the side length and the readable area of the micro-point code point of the universal detection area;
wherein, the readable area of the micro-point code point refers to: for a common mobile phone camera, after focusing can be successfully completed within a focusing distance (1-20 cm according to the known method) and image acquisition is performed (namely under the condition of clear images), the code points at different positions can be distinguished to be 2 code points instead of 1 code point in a pixel area in the image, the printing physical area after the micro-point code points are distinguished, the common code point is lower than 10 microns, and most of images acquired by the mobile phone camera are difficult to distinguish whether the code point exists. Specifically, in order to ensure that the number of code points can be accurately resolved, when generating the micro-point code, firstly, the readable areas (which may be square) of the readable areas are arranged by referring to the readable areas of the code points, and then, in each readable area, the code points are set according to the side lengths of the code points. Other methods for generating the micro-point code according to the micro-point code value and the like can refer to the disclosed prior art, and are not described herein.
In addition, as described above, the gray value of the image of the micro dot code is less than 20, and the image is printed in a dark color, preferably K100, which is easier to read. The average size of the micro-point code points of the universal detection area is preferably 100 micrometers, and the side length median of the micro-point code points is 50-200 micrometers. The size ensures that the micro-point code does not influence the color two-dimensional code in the aspect of industrial vision acquisition. Meanwhile, the size of the relative common micro-point code is increased and adjusted, so that the small program of the mobile phone of a consumer can be conveniently read. The smallest readable region (only so many regions are blocked elsewhere to accomplish decoding and reading of the micro-point code) has a diameter of n millimeters (1 < n < 3, n being a real number), preferably 2mm. The fault tolerance of the micro point code in the area is ensured to be more than 88%. The damage to the label by the blowby only left a complete 12% area (12 mm x 12mm stored 4 x 4mm, 16/144=11.11%) still enabled the dealer to trace back.
Step S106, setting the side length and readable area of the micro-point code points of the inspection detection area;
step S107, generating a second image of the micro-point code around the first image of the micro-point code according to the micro-point code value and the side length and readable area of the micro-point code point of the inspection detection area;
the method comprises the steps of checking the length of the micro-point code points of a detection area, setting the length of the micro-point code points to be 10-50 microns, wherein the length of the micro-point code points is almost invisible to naked eyes, a small program of an intelligent machine is difficult to read, an electrochemical aluminum screen technology is supported to be overlapped on the upper layer of digital printing ink, the aesthetic feeling and the high-grade sense of a label are enhanced, and meanwhile interference on micro-point code reading is introduced, so that the micro-point code reading can be realized as long as an arbitrary 4 mm-4 mm complete area is kept. The minimum readable area is supported to 2mm x 2mm. The inspection detection area consists of non-open source micro-point codes which can be read by a special reader PDA, supports arbitrary aesthetic pattern design, has the fault tolerance of more than 50% of blank area in the minimum readable area, and can support that more than 50% of color blocks on the background can still be read.
Step S108, combining the image of the color two-dimensional code, the first image of the micro-point code and the second image of the micro-point code, wherein the first image of the micro-point code is overlapped on the image of the color two-dimensional code to form a universal detection area, and the corresponding relation between the image of the color two-dimensional code and the first image of the micro-point code is stored for correlation verification when a consumer inquires; and forming an inspection detection area around the universal detection area through the second image of the micro-point code, and storing the corresponding relation between the image of the color two-dimensional code and the second image of the micro-point code for inspection and confirmation by inspection personnel during inspection.
And combining the image of the color two-dimensional code with the image of the micro-point code of the universal detection area, and outputting the image of the micro-point code of the inspection detection area as a printing image. And storing the image of the color two-dimensional code, and establishing a one-to-one correspondence between the color two-dimensional code value and the micro-point code value to a database. FIG. 2 is a schematic diagram of a universal detection area according to an embodiment of the present invention, where, as shown in FIG. 2, the universal detection area is composed of a color two-dimensional code and a micro-point code; fig. 3 is a schematic diagram of a universal detection area and an inspection detection area according to an embodiment of the present invention, where, as shown in fig. 3, the universal detection area is composed of a color two-dimensional code and a micro-point code, and the inspection detection area is composed of the micro-point code.

The consumer can sweep the code to the current mark by using a WeChat sweep and a sweep, and the consumer is guided to enter anti-counterfeiting traceability verification; the intelligent mobile phone checking program obtains a two-dimensional code value through an image and a two-dimensional code open source algorithm, performs two-dimensional code value checking, and ensures the existence and state correctness of the code value; then the smart phone inspection program obtains the image content of the micro-point code through a specific algorithm, and verifies the micro-point code value to ensure the existence of the micro-point code value and the correctness of the association relation; then the intelligent mobile phone checking program inquires the original color two-dimensional code image corresponding to the database according to the micro-point code value; and finally, the consumer can compare the original color two-dimensional code image with the color distribution of the current mark so as to ensure the authenticity of the product marked by the current mark.
The auditing personnel scans the current mark by using a code scanning auditing program to guide the auditing personnel to enter auditing; the specific inspection program obtains the image content of the micro point code and the related data behind the micro point code, decodes the acquired image micro point code decoding algorithm to obtain the color two-dimensional code value, the image, the production and the logistics information which are related to the parallel network inquiry of the micro point code value, and displays the color two-dimensional code value, the image, the production and the logistics information on an interface for comparison and channel conflict inspection confirmation of a user; and finally, the auditing personnel inputs the information of the channel conflict products and the area and stores the channel conflict auditing historical data, so that the condition of the historical auditing can be traced back conveniently.
