Detailed Description
The present application is described in further detail below with reference to figures 1-2.
The embodiments of the present application will be described in further detail with reference to the drawings attached hereto.
The embodiment of the application discloses an anti-counterfeiting identification method, as shown in figure 1, comprising the following steps:
s1: the anti-counterfeiting method comprises the steps of setting an anti-counterfeiting carrier, namely a label, setting a first anti-counterfeiting mark on the label, setting a plurality of randomly distributed anti-counterfeiting images on the first anti-counterfeiting mark, and randomly forming the postures and positions of the anti-counterfeiting images. The anti-counterfeiting carrier can adopt a label, the label comprises release paper and base paper to be processed, a laser surface is arranged on one side of the base paper opposite to the release paper, and a first anti-counterfeiting mark is stamped out on the laser surface through a mold. The first anti-counterfeiting mark can comprise 3D images with a plurality of positions and postures, and the die is cut to form the first anti-counterfeiting mark with random anti-counterfeiting imaging through a random cutting path. The 3D image can be a plurality of diamond icons with different positions and postures, and can also be other regular-shaped pictures or irregular-shaped icons.
The step of S1 further includes how to arrange the first anti-counterfeiting mark and the plurality of randomly distributed anti-counterfeiting images thereon:
s101: an imaging mold is provided, the end of the mold having a predetermined image. The preset image can be a diamond icon, and also can be other regular-shaped pictures or irregular-shaped icons.
S102: and a plurality of adjacent preset images are stamped on the label by using an imaging mould, the plurality of preset images form a first anti-counterfeiting mark, and a laser surface is arranged on the first anti-counterfeiting mark. In the manufacturing process, adjacent preset images are stamped on the laser surface, so that laser images are formed on the label, and the imaging effects at different angles are different. Therefore, during scanning, when the scanned light passes through the laser image, the angle of the light source irradiating the preset image can be changed, the obtained image effect is distorted, the copied printing carrier cannot restore the same effect, and the anti-counterfeiting effect is improved.
The step S102 further includes a mode of pressing the imaging mold: the postures of the imaging mould for each imprinting are different, and after the imprinting, the adjacent preset images on the anti-counterfeiting carrier are overlapped, tightly attached and/or provided with gaps. The randomness of the imaging effect can be improved by overlapping, clinging and/or arranging gaps among the preset images, the anti-counterfeiting effect is improved, and particularly the anti-counterfeiting effect of the partial overlapping arrangement between the adjacent preset images is particularly prominent. After the adjacent images are partially overlapped, the imaging is more complex, the anti-counterfeiting effect is further improved by combining the 3D impression effect on the laser surface, and the copying difficulty is improved.
After S102, a step of cutting the shape of the label itself is also included:
s103: and cutting labels with the same shape and different surface images according to a preset path or a random path. The label with the anti-counterfeiting effect can be generated by cutting according to the preset path, and the randomness of the laser pattern on the label can be improved by cutting according to the random path, so that the anti-counterfeiting effect is further improved.
S2: and a second anti-counterfeiting mark is arranged on the label, is attached to the first anti-counterfeiting mark and shields the partial area of the anti-counterfeiting image. The second anti-counterfeiting mark can be a two-dimensional code, under normal conditions, the two-dimensional code is a square white bottom and a black square, and the two-dimensional code is located in the middle of the anti-counterfeiting carrier and can also be at the edge. In other cases, the two-dimensional code may be a transparent bottom and a black square, the first anti-counterfeiting mark is white, silver white or silver, and the color difference between the first anti-counterfeiting mark and the black square is enough for the device for identifying the two-dimensional code to identify the two-dimensional code. At the moment, the two-dimensional codes on different anti-counterfeiting carriers are different, the black squares are also different in distribution, and the image displayed by the first anti-counterfeiting mark exposed among the black squares has uniqueness and randomness, so that the anti-counterfeiting effect is improved.
S3: before leaving the factory, shooting the anti-counterfeiting carrier by using a camera device for identifying and analyzing the second anti-counterfeiting mark, and generating a first image, wherein the first image comprises the second anti-counterfeiting mark and the first anti-counterfeiting mark shielded by the second anti-counterfeiting mark. And shooting a plurality of images under different light conditions and different angle conditions, wherein the first image is a combination of one or more of the plurality of images.
The edge of the square white bottom of the two-dimensional code shields part of the image on the first anti-counterfeiting mark and also exposes part of the image, and the exposed part can improve the anti-counterfeiting effect, because partial position deviation exists when the second anti-counterfeiting mark is printed, the partial position deviation is a favorable factor for improving the anti-counterfeiting effect. When shooting, the anti-counterfeiting carrier is irradiated by light from different angles, an image is correspondingly generated by changing the angle and/or the light every time, pixel values of the same pixel point in continuous images are recorded, and a first fitting graph with the same resolution as the images is fitted to the continuously generated pixel values according to matrix arrangement, wherein the first image comprises the first fitting graph. For example, 256 × 256 pixels of one image are selected, pixels with pixel coordinates <125, 125> in the image are selected, and under the condition of light intensity or color change and/or light angle change, 256 × 256 pixels with pixel coordinates <125, 125> in each of the 256 × 256 images which are continuously shot are taken, so that a total of 256 × 256 pixels are formed to participate in comparison.
S4: and after leaving the factory, shooting the anti-counterfeiting carrier by using a camera device for identifying and analyzing the second anti-counterfeiting mark to generate a second image, wherein the second image comprises the second anti-counterfeiting mark and the first anti-counterfeiting mark shielded by the second anti-counterfeiting mark. When shooting, the anti-counterfeiting carrier is irradiated by light from different angles, an image is correspondingly generated by changing the angle and/or the light every time, pixel values of the same pixel point in the continuous image are recorded, a second fitting graph with the same resolution as that of the image is fitted to the continuously generated pixel values according to matrix arrangement, and the second image comprises the second fitting graph.

Different light shines anti-fake carrier from different angles and can demonstrate different formation of image effects, changes the angle at every turn and corresponds and generate an image and can provide more contrast images for the post-factory identification image, improves the degree of accuracy of contrast judgement result. Meanwhile, the image is fitted by utilizing the imaging change of the pixel value of the same pixel point under the conditions of different lights or different angles, and the first fitting image and the second fitting image can be compared under the condition of the same environmental change, so that the later-stage improvement of the comparison precision is facilitated.
S5: and identifying a second anti-counterfeiting mark, calling a first image corresponding to the second anti-counterfeiting mark, comparing and judging the first anti-counterfeiting mark in the second image and the first anti-counterfeiting mark in the first image, and marking the currently identified anti-counterfeiting carrier and prompting if the repetition rate is smaller than a preset first standard value as a result of comparison and judgment.
