Description

Technical Field

[0001] The present invention relates to the field of anti-counterfeiting encryption technology, and more specifically, to a multi-dimensional encoding method, system, decoding method and anti-counterfeiting encryption mark. Background Art

[0002] Laser packaging is a sub-industry in the packaging industry and has achieved rapid development in recent years. Compared with other products in the packaging industry, laser packaging materials have a novel and bright appearance and are known as the most cutting-edge technology products in the world's packaging and printing industry.

[0003] Existing laser packaging also includes laser labels attached to products. Laser labels can not only enhance the appearance of products and attract users' attention, but also highlight the information printed or sprayed on the laser labels. The information on the laser label can be a QR code. Users can check the quality information and regional information of the product by scanning the QR code with a smart phone. There is an anti-counterfeiting label in the prior art, which includes an anti-counterfeiting carrier with a laser image. The laser image is an arranged and distributed graphic. A QR code is printed on the laser image. In this case, the laser label can also be called an anti-counterfeiting label. The manufacturer retains the image of the anti-counterfeiting label. The user takes a photo of the anti-counterfeiting label to identify the QR code and the laser image not covered by the QR code and uploads it to the manufacturer. The manufacturer determines the authenticity of the anti-counterfeiting label in the background by identifying the QR code and the laser image covered by the QR code.

[0004] Regarding the above-mentioned related technologies, because the laser image has anisotropic imaging effects, when using a camera to shoot a laser label, if there is a change in the angle or posture between the camera and the laser label, it is easy to change the imaging effect of the laser label, which increases the difficulty of background recognition of the laser label and reduces the recognition success rate. Summary of the invention

[0005] In order to improve the recognition success rate of existing laser labels, the present invention provides a multi-dimensional encoding method, system, decoding method and anti-counterfeiting encryption label.

[0006] In a first aspect, the present application provides a multi-dimensional encoding method, which adopts the following technical solution:

DETAILED DESCRIPTION

[0071] The following is combined with Figure 1-8 The present invention is described in detail with reference to the accompanying drawings and embodiments.

[0072] Embodiment 1:

[0073] A multi-dimensional encoding method comprises the following steps:

[0074] S1: Set up anti-counterfeiting carrier 1. Figure 1 and Figure 2As shown, the anti-counterfeiting carrier 1 is a laser label, and the laser pattern on the laser label is printed by combining multiple laser templates 0. The multiple laser templates 0 can be the same, and can all be selected as equilateral hexagons for easy arrangement. The laser template 0 is used to print laser, relief and micro-carving patterns on the anti-counterfeiting carrier 1. In other embodiments, the multiple laser modules 0 can also be different. After the multiple laser templates 0 are combined in different arrangements, different laser labels can be printed, and during the printing process, the positions of the laser templates 0 are randomly arranged or randomly placed to achieve the random setting of the pattern on the laser label. After the multiple laser templates 0 are arranged, the anti-counterfeiting carrier 1 is printed, and the required label shape can be cut out on the scroll-shaped anti-counterfeiting carrier 1, and then the cut laser label is subjected to subsequent printing processing. In other embodiments, if the arranged laser templates 0 are not changed and the edge overlap of the laser pattern printed on the laser label is randomly changed, the random setting of the pattern on the laser label can also be achieved.

[0075] like Figure 3 As shown, a first anti-counterfeiting mark 2 is provided on the anti-counterfeiting carrier 1. The first anti-counterfeiting mark 2 is a plurality of patterns on a laser label. The patterns may be various and different from each other. The patterns may be other patterns such as diamonds, shaped blocks or symbols. Figure 4 As shown, in this embodiment, the pattern is a variety of different diamonds, and the diamonds can be formed by splicing a plurality of polygons, and the polygons can be triangles, quadrilaterals, etc. The first anti-counterfeiting mark 2 includes a plurality of randomly distributed anti-counterfeiting images 3, and the anti-counterfeiting images 3 are patterns such as diamonds, shape blocks or symbols, and the posture and position of the anti-counterfeiting images 3 are randomly formed. A marking image 4 is correspondingly arranged on the anti-counterfeiting image 3, and the marking image 4 is a relief pattern arranged on the pattern. The relief pattern can be other patterns such as numbers, shape blocks or symbols. The marking image 4 can be arranged in the middle position of the anti-counterfeiting image 3. In this embodiment, the relief pattern is a digital pattern. There are ten kinds of diamonds in the pattern, and each diamond corresponds to a digital pattern, the numbers are 0-9, and the digital pattern is smaller than the diamond pattern and is located in the middle position of the diamond pattern. In other embodiments, a part of the marking image 4 can be covered on the anti-counterfeiting image 3. In this embodiment, a laser label is provided with multiple diamond patterns and multiple digital patterns.

[0076] The anti-counterfeiting image 3 is provided with at least one anti-counterfeiting tile 31 with different anisotropic properties, and the anti-counterfeiting tile 31 can be a polygon that is assembled into a diamond shape; the marking image 4 is provided with at least one marking tile 41, and the shape of the marking tile 41 is a digital shape or a part of a digital shape, and the anisotropic property of the marking tile 41 is different from the anisotropic property of the anti-counterfeiting tile 31. The anisotropic property is that the imaging effect is different when the light position is different at the same observation position; in other embodiments, the anisotropic property is that the imaging effect is different when the light position is the same at different observation positions; or, the imaging effect is different when the observation position is different and the light position is different. The number of tiles with different anisotropic properties on the marking image 4 is not higher than the number of tiles with different anisotropic properties on the anti-counterfeiting image 3. In this embodiment, the number of tiles of the marking image 4 is one, and the number of tiles of the anti-counterfeiting image 3 is greater than or equal to two. The marking tile 41 is covered with at least one anti-counterfeiting tile 31, and the marking image 4 corresponds to a marking code, which is digital content.

[0077] like Figure 5 As shown, there is a gap between the anti-counterfeiting blocks 31, and a first micro-carved mark 6 is provided in the gap, and the first micro-carved mark 6 can be a preset name, text or graphic, etc. A second micro-carved mark 7 is provided on the anti-counterfeiting block 31, and the second micro-carved mark 7 can be a trademark, name, text or graphic, etc. The first micro-carved mark 6 and the second micro-carved mark 7 improve the anti-counterfeiting effect of the method in this embodiment.

[0078] At least one filling mark 5 is randomly arranged next to the first anti-counterfeiting mark 2. The filling mark 5 can be an image such as a number, letter or symbol set by a plurality of micro-carvings. The filling mark 5 is arranged around the first anti-counterfeiting mark 2 and fills the space between adjacent first anti-counterfeiting marks 2. Part of the filling mark 5 is covered by the first anti-counterfeiting mark 2. The edge of the anti-counterfeiting image 3 is provided with an indication angle 32. The filling mark 5 is used as another anti-counterfeiting mark after corresponding to the indication angle 32, which improves the anti-counterfeiting effect of the method in this embodiment. In this embodiment, there are multiple filling marks 5 and they are letters. The tip of the diamond pattern covers a letter. At this time, the relative posture imaging of the diamond tip and the letter can improve the anti-counterfeiting effect of the method in this embodiment. In other embodiments, the tip of the diamond does not cover the letter, but points to a letter. At this time, the relative posture imaging of the diamond tip and the letter can also improve the anti-counterfeiting effect of the method in this embodiment.

[0079] like Figure 4 and Figure 6As shown, S2: photograph the anti-counterfeiting carrier 1, identify the anti-counterfeiting image 3 and the mark image 4, and generate the outline of the anti-counterfeiting image 3 and the outline of the mark image 4. Use a camera to photograph the anti-counterfeiting carrier 1 to obtain an image of the anti-counterfeiting carrier 1, use image recognition software to identify the anti-counterfeiting image 3 and the mark image 4, and extract the outline of the anti-counterfeiting image 3 and the outline of the mark image 4. The recognition method can be a template matching method or an artificial intelligence algorithm using a convolutional neural network.

[0080] S3: Identify the relative posture between the contour of the anti-counterfeiting image 3 and the contour of the mark image 4, and put the relative posture into a preset posture template for matching. After the laser template 0 is printed, its printed image will be stored, and the identified relative posture will be matched on the stored image of the laser template 0. The matching method can be a template matching method or an artificial intelligence algorithm using a convolutional neural network.

[0081] like Figure 3 and Figure 6 As shown, S4: if the relative posture is matched from the posture template, the mark code of the mark image 4 corresponding to the relative posture is added to the preset code library; if it cannot be matched, jump to S1. If it can be matched, it means that the laser label is not wrong. In this embodiment, four diamond patterns and four numbers on the laser label are recognized, which is 1029. Along the label from top to bottom and from left to right, that is, 1 is in the upper left corner, 0 is in the lower left corner, 2 is in the lower right corner, and 9 is in the upper right corner. There are four code marks, which are combined into 1029.

[0082] S5: Encrypt the tag codes in the coding library according to the preset encryption algorithm to generate an encryption symbol. The encryption algorithm includes the following steps: Obtain all the coding tags in the coding library. If the number of coding tags is less than the preset number of tags, the preset complement code is used to complement the number of coding tags to the preset number of tags. Merge the coding tag and the complement code into an encryption symbol. In this embodiment, the preset number of tags is four, so the number of tags of 1029 meets the conditions and does not need to be complemented. In other embodiments, if three diamond patterns and three numbers are identified on a laser label, it is 132. Arrange the labels from top to bottom and from left to right, that is, 1 is in the upper left corner, 3 is in the lower left corner, and 2 is in the lower right corner, then use 8 to complement and merge into 1328. 8 is a preset complement code, and the complement code can also use other numbers, letters or symbols. The preset complement code complements the number of coding tags to allow the complemented coding tags to participate in the calculation, thereby improving the encryption effect of the method.

[0083] S6: Set a second anti-counterfeiting mark 8 associated with the verification information, and generate an anti-counterfeiting code after associating the encryption symbol with the verification information, and the verification information points to the anti-counterfeiting code. Cover the second anti-counterfeiting mark 8 on the first anti-counterfeiting mark 2, and the position of the second anti-counterfeiting mark 8 does not overlap with the mark imaging 4 involved in encryption. The second anti-counterfeiting mark 8 is a printed two-dimensional code, and the verification information is the string code pointed to by the scanned two-dimensional code. The string code is a string of label digital IDs. The encryption symbol and the selection number corresponding to the format in the verification information are calculated to obtain the anti-counterfeiting code. The selection number can be a number pre-selected for multiple positions, or a number selected according to the position after the position is calculated according to the set algorithm. This embodiment takes the number pre-selected by the position as an example, such as, the string code is 46876546249146418, and the last four digits 6418 and 1328 are added to obtain 7746, and the anti-counterfeiting code is 7746, which further improves the encryption effect of the method. The association algorithm can also use other algorithms such as subtraction and multiplication.

[0084] The beneficial effects of this embodiment are as follows: the first anti-counterfeiting is achieved by using the anti-counterfeiting image 3 and the marking image 4, and multiple groups of corresponding patterns are set on the laser label, such as the anti-counterfeiting image 3 and the marking image 4 are a group, the marking block 41 and the anti-counterfeiting block 31 are a group, the anti-counterfeiting image 3 and the filling mark 5 are a group, and the first micro-carved mark 6 and the second micro-carved mark 7 are a group, which can improve both the recognition effect and the anti-counterfeiting performance. The anti-counterfeiting image 3 has a more prominent recognition degree under the comparison of the anti-counterfeiting image 3, which reduces the difficulty of recognition, and the anisotropic properties of the anti-counterfeiting block 31 are different from the anisotropic properties of the marking block 41, which further improves the anti-counterfeiting performance.
