It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention.

[0040] Embodiment 1

[0041] Figure 1 This is a flowchart of the anti-counterfeiting method provided in the first embodiment of the present invention. This embodiment is applicable to the case where an anti-counterfeiting code is set on any product for anti-counterfeiting. The method can be executed by the anti-counterfeiting device provided in the embodiment of the present invention. The device can be implemented by hardware and / or software, and can generally be integrated into a computer device. Figure 1 As shown, the specific steps include:

[0042] S11. Printing color ink on the target object using CMYK color mode to form a microscopic coded image on the target object, wherein the microscopic coded image includes code points of at least one color.

[0043] Among them, the microscopic coding image is an image composed of code points in micrometers according to certain arrangement rules, which contains variable data information, can realize one code for one object, and the coding is not repeated. Because the code points are very small and difficult to distinguish with the naked eye, they have a good hiding effect and can be well combined with the printed logo of the product. The current mainstream color ink printing adopts the CMYK color mode of 4 primary colors, that is, using four colors of ink: C (cyan), M (magenta), Y (yellow) and K (black). White light is a mixture of red, green and blue light. When white light is irradiated on inks of various colors, C (cyan) ink can absorb red light, retain green and blue light and present cyan, M (magenta) ink can absorb green light, retain red and blue light and present magenta, Y (yellow) ink can absorb blue light, retain red and green light and present yellow, and K (black) ink can absorb all three colors of red, green and blue light and present black. Specifically, the inks of various colors mentioned above can be used to print a microscopic coded image at a preset position on the surface of the target object, so that the microscopic coded image includes code points of at least one color.

[0044] Optionally, the CMYK color mode is used to print color ink on the target object to form a microscopic coded image on the target object, including: using three color channels C, M and Y to form cyan code points, magenta code points and yellow code points respectively. Specifically, in traditional color ink printing, due to the limitation of production technology, the purity of ink is often unsatisfactory, so that the black mixed by the three color inks of cyan, magenta and yellow is not rich enough, and can only be mixed by purified K (black) ink. However, in this embodiment, the subsequent anti-counterfeiting verification process can be realized by relying on the various colors of inks to absorb different colors and only absorb one color of light. At the same time, the microscopic coded image itself is difficult to distinguish with the naked eye, and there is no high requirement for the actual displayed color. Therefore, only cyan, magenta and yellow inks can be used to print the code points in the microscopic coded image, wherein each color of ink can use a color channel to realize independent printing, that is, cyan ink can print cyan code points through the C color channel, magenta ink can print magenta code points through the M color channel, and yellow ink can print yellow code points through the Y color channel. Before printing, the code point patterns of each color channel can be generated respectively, and each color channel can be controlled according to each code point pattern to realize independent printing, that is, each color can be printed layer by layer, and each code point pattern can be superimposed to generate a final pattern first, and then printed directly according to the pattern. It should be noted that for the microscopic coded images of all the target objects, the above three colors of ink can be used to form code points, and for the microscopic coded image of a specific target object, code points of at least one color can still be formed.

[0045] Further optionally, after the three color channels C, M and Y are used to form cyan code points, magenta code points and yellow code points respectively, it also includes: using the code points formed by each of the color channels to independently form multiple microscopic coded images. Specifically, there can be multiple microscopic coded images, and each microscopic coded image can only include code points of one color, wherein each microscopic coded image can be set at different positions on the surface of the target object without overlapping. Then, in the subsequent anti-counterfeiting verification process, each microscopic coded image can be verified separately, and the anti-counterfeiting verification is determined to be passed only when all the microscopic coded images pass the verification, and the anti-counterfeiting verification can also be determined to be passed when some of the microscopic coded images pass the verification, so as to further improve the anti-counterfeiting effect.

[0046] Further optionally, after the three color channels C, M and Y are used to form cyan code points, magenta code points and yellow code points respectively, the method further includes: the code points formed by each color channel are used together to form a microscopic coding image. Specifically, the microscopic coding image can be one, that is, the microscopic coding images formed by each color channel can be aligned and superimposed together to form a microscopic coding image. In the subsequent anti-counterfeiting verification process, the microscopic coding image can be verified by the three color channels R, G and B to determine whether the code points of different colors can pass the verification, and the anti-counterfeiting verification is determined to be passed only when all the code points of all colors pass the verification. It can also be specified that the anti-counterfeiting verification is determined to be passed when the code points of some colors pass the verification, so as to further improve the anti-counterfeiting effect.

[0047] Further optionally, when there is only one microscopic coding image, the code points formed by each color channel partially or completely overlap in the microscopic coding image. Of course, they may not overlap at all. When there are multiple microscopic coding images, the code points formed by each color channel naturally do not overlap at all. Specifically, the code points formed by different color channels can overlap, that is, it is allowed that there are code points formed by two or more color channels on the same coordinate. When there is an overlap between cyan ink, magenta ink and yellow ink, the light of each corresponding color can be absorbed. For example, when cyan ink and magenta ink are superimposed, red and green light can be absorbed while blue light is retained, thereby presenting a blue color. Since code points of different colors can overlap, after printing is completed, there may be cyan, magenta, yellow, red, green, blue and black code points on the surface of the target object.

[0048] S12, using the microscopic coded image as an anti-counterfeiting code for anti-counterfeiting.

[0049] Specifically, after the above-mentioned microscopic coded image is printed on the target object, the microscopic coded image can be combined with color ink printing according to the light absorption characteristics of the above-mentioned various colors of ink, so that the color microscopic coded image printed with color ink can be used as an anti-counterfeiting code for anti-counterfeiting. Since the microscopic coded images use code points of micron size, it is easy to lose the code points when copying at the micron scale, which will cause the code points to be lost or the code points to change significantly in size. Therefore, the authenticity can be identified by distinguishing them during identification. Specifically, to copy the color microscopic coded images, color copying equipment or scanning and printing equipment is required. However, whether it is copying or scanning and then printing, the process is to first image and then restore it to CMYK color mode data before printing. Due to performance and accuracy limitations, these devices are not very ideal in restoring colors at the micron scale, which will more or less cause the loss of some code points or color errors. In particular, when there are more than two colors of code points overlapping, the color error after restoration will be even greater, causing serious interference between the code points on the C, M, and Y channels, thereby causing the subsequent anti-counterfeiting verification process to fail to parse. Therefore, the anti-counterfeiting method provided in this embodiment can achieve better anti-counterfeiting effects. At the same time, using multiple color channels to form code points of different colors can contain more information, that is, three times that of a single color channel. Because it is a color-coded image, the code points can have up to seven colors, thus forming a colorful visual effect, making the target object more beautiful as a whole.

[0050] On the basis of the above technical solution, optionally, after the microscopic coding image is used as an anti-counterfeiting code for anti-counterfeiting, it also includes: obtaining the image data of the microscopic coding image on the three color channels of R, G and B on the target object; determining the color, position and size of the code point according to the image data on each color channel; and performing anti-counterfeiting verification according to the color, position and size of the code point. Specifically, when anti-counterfeiting verification is required, a color image including the microscopic coding image on the target object can be first captured under natural light or white light using a mobile phone or a dedicated reading device, and the microscopic coding image in the color image can be cut out according to the edge features or positioning features of the microscopic coding image. Then, based on the RGB color mode, the color image (specifically, the microscopic coding image part) can be separated into the image data of the three color channels of R (red), G (green) and B (blue), so that the position and size of the code points of various colors in the image can be determined according to the light absorption characteristics of the above-mentioned various colors of ink and the image data on each color channel. A dedicated reading device can also be used to illuminate the microscopic coded image on the surface of the target object with three light sources of R (red), G (green) and B (blue), and capture the image data of the corresponding three color channels of R (red), G (green) and B (blue), so as to determine the position and size of the code points of various colors in the image. The former has better universality and can be realized using general devices such as mobile phones, while the latter must use dedicated equipment, but relatively speaking, the separation of the three color channels is higher, so it has higher accuracy. After determining the color, position and size of each code point, this information can be compared with the target microscopic coded image, or this information can be searched in the microscopic coded image database to determine whether the microscopic coded image in the currently captured color image is true. The specific image analysis process and the anti-counterfeiting verification process are not specifically limited in this embodiment, wherein the target microscopic coded image can be a reserved real microscopic coded image corresponding to the current target object.

[0051] Further optionally, the anti-counterfeiting verification according to the color, position and size of the code point includes: performing anti-counterfeiting verification on the microscopic coded images independently formed by the code points of each color, and determining the authenticity of the target object according to each verification result. Specifically, after determining the color, position and size of each code point, the code points of the same color can be extracted respectively, and each microscopic coded image can be formed respectively, and then each microscopic coded image can be subjected to anti-counterfeiting verification. The specific verification method includes but is not limited to the above-mentioned verification method, such as comparing each microscopic coded image with its corresponding target microscopic coded image, or searching each microscopic coded image in a microscopic coded image database, etc. After obtaining the verification results of each microscopic coded image, the authenticity of the target object can be finally determined according to each verification result, such as determining that the target object is authentic when all verifications are passed, or determining that the target object is authentic when a preset part of the verifications are passed, etc.

[0052] Further optionally, determining the color, position and size of the code point according to the image data on each of the color channels includes: if a dark spot appears in the image data on the R color channel, determining that at least the cyan code point formed by the C color channel is required in the micro-coded image, and determining the position and size of the cyan code point according to the dark spot that appears; if a dark spot appears in the image data on the G color channel, determining that at least the magenta code point formed by the M color channel is required in the micro-coded image, and determining the position and size of the magenta code point according to the dark spot that appears; if a dark spot appears in the image data on the B color channel, determining that at least the yellow code point formed by the Y color channel is required in the micro-coded image, and determining the position and size of the yellow code point according to the dark spot that appears. Specifically, when the code points do not overlap: the cyan code point absorbs red light and retains green and blue light, then the code point appears as a dark dot in the R color channel of the color image, and has no obvious features in the G and B color channels; the magenta code point absorbs green light and retains red and blue light, then the code point appears as a dark dot in the G color channel of the color image, and has no obvious features in the R and B color channels; the yellow code point absorbs blue light and retains red and green light, then the code point appears as a dark dot in the B color channel of the color image, and has no obvious features in the R and G color channels. When there are two or more code points of different colors overlapping: when the cyan code point and the magenta code point overlap, they absorb red and green light and retain blue light, then the code point appears as a dark spot in both the R and G color channels of the color image, and has no obvious features in the B color channel; when the cyan code point and the yellow code point overlap, they absorb red and blue light and retain green light, then the code point appears as a dark spot in both the R and B color channels of the color image, and has no obvious features in the G color channel; when the magenta code point and the yellow code point overlap, they absorb green and blue light and retain red light, then the code point appears as a dark spot in both the G and B color channels of the color image, and has no obvious features in the R channel; when the cyan code point, magenta code point and yellow code point all overlap, they absorb light of three colors, then the code point appears as a dark spot in the R, G and B color channels of the color image. It can be seen that by separating the image data of the microscopic coded image on the three color channels of R, G and B, the images of the code points of the three colors of cyan, magenta and yellow can be filtered out, and then processed separately to obtain the positions and sizes of the code points of various colors. Even if there is overlap between the code points of different colors, there is no interference. The positions can be the coordinate positions in the coordinate system established with the edge of the microscopic coded image as the coordinate axis, etc.

[0053] For example, Figure 2As shown, code points are set in the three color channels of C (cyan), M (magenta) and Y (yellow), and these code points do not overlap, wherein the number of code points contained in the three channels is 12, 11 and 14 respectively. Since the code points do not overlap, after the three channels are superimposed, the number of code points contained is the sum of the number of code points contained in each of the three channels, that is, 37. After the superimposed image is printed, all the code points of the three channels will be contained on the surface of the target object. After the image data of the three color channels of R (red), G (green) and B (blue) of the microscopic coded image on the surface of the target object is obtained by a mobile phone or a dedicated device, the coordinates of the code points in the three color channels of R, G and B (corresponding to the C, M and Y color channels in the original microscopic coded image, respectively) and the size of the code points can be calculated respectively, and the authenticity can be further identified by analysis.

[0054] For example, Figure 3 As shown in FIG. 1 , code points are set in the three color channels C (cyan), M (magenta) and Y (yellow), and some code points overlap. The number of code points contained in the three channels is 14, 11 and 14 respectively. Figure 4 In the code point 1 and code point 2 are respectively formed by overlapping a code point on the C and M color channels, and code point 3 and code point 4 are respectively formed by overlapping a code point on the C, M and Y color channels). After the three channels are superimposed, the number of code points contained is 33, which is less than the sum of the number of code points of the three channels, 39. After the superimposed image is printed on the surface of the target object, code point 1 and code point 2 appear blue due to the superimposition of cyan and magenta inks, which absorb red and green light respectively, and code point 3 and code point 4 appear black due to the superimposition of cyan, magenta and yellow inks, which absorb red, green and blue light respectively. Then, after the image data of the three color channels R (red), G (green) and B (blue) of the microscopic coding image on the target object is captured by a mobile phone or a dedicated device, the coordinates and sizes of the code points in the three color channels R, G and B (corresponding to the C, M and Y color channels in the original microscopic coding image, respectively), can be calculated respectively, and the authenticity can be further identified by analysis.

[0055] The technical solution provided by the embodiment of the present invention first adopts the CMYK color mode to print color ink on the target object to form a microscopic coding image on the target object, wherein the microscopic coding image includes code points of at least one color, and then the obtained microscopic coding image can be used as an anti-counterfeiting code for anti-counterfeiting. By using the microscopic coding image, especially the color microscopic coding image as the anti-counterfeiting code, the difficulty of copying the anti-counterfeiting code is increased, thereby achieving a better anti-counterfeiting effect. At the same time, the microscopic coding image is printed on the target object by color ink printing, so that the microscopic coding image can include code points of multiple colors, so that the anti-counterfeiting code can carry more information to meet the quantity requirements of various products, and the use of the color microscopic coding image as the anti-counterfeiting code can also form a colorful visual effect, making the target object more beautiful as a whole.
