Abstract
Description
Technical Field
[0001] The present invention relates to the field of anti-counterfeiting labels, and in particular to an anti-counterfeiting identification method and an anti-counterfeiting label applied to the method. Background Art
[0002] The significance of anti-counterfeiting labels is that they are a solution and effective means for brand users to protect their own brands. However, choosing anti-counterfeiting technology is also a major problem for us at present. Ordinary users do not know where to start when choosing anti-counterfeiting technology, because first of all, we do not have an in-depth understanding of anti-counterfeiting technology. We only know that it is an identity card of a product that cannot be copied. However, the resident identity card is unified, and anti-counterfeiting technology must be tailored.
[0003] The anti-counterfeiting features and identification methods of anti-counterfeiting labels are the soul of anti-counterfeiting labels. Anti-counterfeiting is a preventive measure taken against activities that are imitated or copied for the purpose of deception without the permission of the owner.
[0004] Currently, the anti-counterfeiting labels on the market are usually a segment of numbers, or a barcode or QR code. Once such anti-counterfeiting labels are obtained by unauthorized persons, they can be easily copied through conventional printing methods, so their anti-counterfeiting capabilities are worrying. Summary of the invention
[0005] The purpose of the present invention is to provide an anti-counterfeiting label, which has the advantages that the distribution of the anti-counterfeiting strip on the label body is uncertain, and it is difficult for criminals to forge similar counterfeit labels based on existing labels, so the anti-counterfeiting effect is good and the counterfeiting difficulty is high.
[0006] The above technical purpose of the present invention is achieved through the following technical scheme: an anti-counterfeiting label, including a label body, a bonding layer is provided on the surface of the label body, and a plurality of anti-counterfeiting strips are provided on the bonding layer, and the anti-counterfeiting strips are provided with at least two end points.
[0007] Through the above technical solution, the anti-counterfeiting strip is bonded to the adhesive layer, so it is not easy to move or fall off, and because the anti-counterfeiting strip is provided with at least two endpoints, the operator can connect the two endpoints on the anti-counterfeiting strip into a measuring line, and judge the authenticity of the product based on all the measuring lines formed by the two endpoints of all the anti-counterfeiting strips. Due to the uncertainty of the distribution of the anti-counterfeiting strips on the label body, it is difficult for criminals to forge similar counterfeit labels based on existing labels, so the anti-counterfeiting effect is good and the counterfeiting difficulty is high.
[0008] The present invention is further configured as follows: a limiting frame strip is provided at the periphery of the bonding layer.
[0009] Through the above technical solution, the limiting frame strip can separate the adhesive layer and the outer edge of the label body, so that the distribution area of the adhesive layer and the anti-counterfeiting strip is fixed, which makes it easier for later users to collect the distribution information of the anti-counterfeiting strip in the fixed area.
[0010] The present invention is further configured as follows: a transparent protective layer is also provided on the adhesive layer, and the anti-counterfeiting strip is located between the transparent protective layer and the adhesive layer.
[0011] Through the above technical solution, the transparent protective layer can cover the anti-counterfeiting strip, thereby protecting the anti-counterfeiting strip and reducing the possibility of the anti-counterfeiting strip detaching from the adhesive layer, thereby ensuring the distribution stability of the anti-counterfeiting strip.
[0012] The present invention is further configured such that a scratching silver layer is coated on the side of the transparent protective layer facing away from the anti-counterfeiting strip.
[0013] Through the above technical solution, when the user needs to view the anti-counterfeiting information, he or she first needs to scrape off the scratch-off silver layer. Once the scratch-off silver layer is scraped off, it is difficult to restore it, thereby ensuring the one-time use of the anti-counterfeiting label and reducing the possibility of vendors repeatedly reselling products.
[0014] The present invention is further configured as follows: the shape of the anti-counterfeiting strip is configured as any one of an L-shape, a check mark shape, a hexagon, a pentagon, a triangle, an S-shape, and a heart shape.
[0015] Through the above technical solution, the shape of the anti-counterfeiting strip can be selected in a variety of ways to meet the needs of different merchants' products, making the anti-counterfeiting labels unique and easy to distinguish.
[0016] The present invention is further configured such that: laser dots are provided on two end points of the anti-counterfeiting strip.
[0017] Through the above technical solution, the laser dot can clearly mark the two endpoints, thereby facilitating the image acquisition device to quickly and accurately capture the two endpoints, thereby improving the speed of anti-counterfeiting information recognition.
[0018] The present invention is further configured such that: the anti-counterfeiting strip is made of any one of fiber, metal, and plastic.
[0019] Through the above technical scheme, the anti-counterfeiting strips made of fiber are light and thin, and the material is easy to shape and low in cost; the anti-counterfeiting strips made of metal have the characteristics of high strength, good surface quality, good texture, and not easy to break, so they can be used on high-end anti-counterfeiting labels; anti-counterfeiting labels made of plastic have good corrosion and moisture resistance, and can ensure that their shape does not change in a humid environment, so they have strong anti-interference ability, which is conducive to improving the stability of anti-counterfeiting information; merchants can choose anti-counterfeiting strips of different materials according to their needs to adapt to the characteristics of their own products.
[0020] Another object of the present invention is to provide an anti-counterfeiting identification method using the anti-counterfeiting label, which has the advantages of low comparison difficulty and high comparison accuracy during anti-counterfeiting query.
[0021] The above technical purpose of the present invention is achieved through the following technical scheme: comprising the following steps: Step 1: before all anti-counterfeiting labels leave the factory, an anti-counterfeiting database is established locally; Step 2: two endpoints on the anti-counterfeiting strip are acquired through an image acquisition device, and the two points are connected to form a measuring line; Step 3: a line is selected as a baseline, and the angles between each measuring line and the baseline are measured and all the angles are arranged from small to large into a sequence A; Step 4: sequence A is compared with the corresponding data in the background anti-counterfeiting database.
[0022] Through the above technical solution, after the consumer gets the product, the image acquisition device captures the two endpoints on all the anti-counterfeiting strips, and connects the two points to form a measuring line, then selects a line as the baseline, and measures the angles between each measuring line and the baseline, and finally arranges all the angles into a series A from small to large, and compares the series A with the corresponding data in the background anti-counterfeiting database. If the comparison results are exactly the same, the product is authentic, otherwise it is a counterfeit product. In this way, on the one hand, the comparison data is pure numerical value, so the comparison difficulty is small and the comparison accuracy is high. On the other hand, it can reduce the possibility of errors in the comparison results when the middle part of the anti-counterfeiting strip itself is damaged or the whole is expanded or contracted due to environmental influences.
[0023] The present invention is further configured as follows: the image acquisition device is configured as a mobile phone, and after comparison, if the sequence A does not match the corresponding data in the background anti-counterfeiting database, a voice alarm is issued through the mobile phone, otherwise no alarm is issued.
[0024] Through the above technical solution, mobile phones are currently extremely common in the market and have powerful functions. Consumers can quickly collect information on anti-counterfeiting labels through the "scan" function of the mobile phone, and generate sequence A according to steps two and three, and compare sequence A with the corresponding data in the background anti-counterfeiting database through the network. If sequence A does not match the corresponding data in the background anti-counterfeiting database, a voice alarm will be issued through the mobile phone, otherwise no alarm will be issued; this allows consumers to quickly and conveniently obtain anti-counterfeiting information, and the comparison speed is also fast.
[0025] The present invention is further configured such that when the number series A is compared with the corresponding data in the background anti-counterfeiting database, each data value in the number series A is allowed to have an error within 0 to 10 with the corresponding data value in the anti-counterfeiting database.
[0026] Through the above technical solution, an error tolerance of 0~10 is given to each data value, which can reduce the numerical deviation caused by shooting angle problems for consumers, thereby reducing unnecessary false alarms. Moreover, since there are multiple anti-counterfeiting strips on an anti-counterfeiting label, the error tolerance is only between 0~10. Therefore, the overall anti-counterfeiting ability will not decrease too much, which fully balances the anti-counterfeiting ability and query difficulty.
[0027] In summary, the present invention has the following beneficial effects:
[0028] 1. The comparison data is pure numerical value, so the comparison difficulty is small and the comparison accuracy is high;
[0029] 2. It can reduce the possibility of errors in the comparison results when the middle part of the anti-counterfeiting strip is damaged or the whole piece expands or shrinks due to environmental influences. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The present invention is further described in detail below in conjunction with the accompanying drawings.
[0039] Embodiment 1: An anti-counterfeiting label, such as Figure 1 and Figure 2, including a label body 1, on which a rectangular limiting frame strip 4 is provided. The limiting frame strip 4 can be set as a black ink strip printed on the label body 1, or as a cardboard strip protruding 10.1mm from the label body. Glue is coated inside the limiting frame strip 4, and the glue condenses into an adhesive layer 2 inside the limiting frame strip 4. The adhesive layer 2 is provided with a number of anti-counterfeiting strips 3 of the same shape, and the anti-counterfeiting strips 3 can be firmly bonded. In this embodiment, the anti-counterfeiting strip 3 is in the shape of a check mark, and the folding angle of the check mark is set to 45°, and the length ratio of the two sides of the check mark is 2:1, and the overall length of the check mark is set to 2.5mm~5mm. At this time, the two endpoints of the check mark-shaped anti-counterfeiting strip 3 except the folding point are set as collection points, and a laser point 31 is respectively provided on the two endpoints (such as Figure 3 ). The laser point 31 has a high degree of reflectivity, so that consumers can quickly collect the two endpoints.
[0040] like Figure 1 and Figure 2 The label body 1 is also provided with a transparent protective layer 5 on the adhesive layer 2. The periphery of the transparent protective layer 5 is glued to the outer periphery of the limit frame strip 4 by glue. At this time, the transparent protective layer 5 can protect the anti-counterfeiting strip 3 on the adhesive layer 2 to reduce the possibility of rainwater penetrating the adhesive layer 2 and causing the anti-counterfeiting strip 3 to shift, and can also reduce the possibility of the anti-counterfeiting strip 3 detaching from the adhesive layer 2 under external forces. The side of the transparent protective layer 5 facing away from the anti-counterfeiting strip 3 is coated with a scratching silver layer 6, and the thickness of the scratching silver is set to 0.1mm, so as to completely cover the position distribution information of the anti-counterfeiting strip 3 on the adhesive layer 2, reducing the possibility of lawless elements stealing the anti-counterfeiting information. When it is necessary to view the anti-counterfeiting information, the consumer can directly scratch the scratching silver layer 6 to expose the anti-counterfeiting strip 3 on the adhesive layer 2, so as to quickly and conveniently query.
[0041] like Figure 3 In order to meet the needs of different customers, the shape of the anti-counterfeiting strip 3 can also be set to an L shape (such as Figure 4 ), hexagon, pentagon (such as Figure 5 ), triangle (such as Figure 6 ), S-shaped or heart-shaped (such as Figure 7 ), two laser points 31 are randomly distributed on the two ends of the anti-counterfeiting strips 3 of these shapes. The anti-counterfeiting strips 3 of different shapes make the selection diverse, which can meet the needs of different merchants' products, making the anti-counterfeiting labels distinctive and easy to distinguish.
[0042] like Figure 3 The anti-counterfeiting strip 3 is made of fiber. The anti-counterfeiting strip 3 made of fiber is light and thin, and the material is easy to shape, the cost is low, and the whole label has good softness, which is very suitable for bottled goods.
[0043] Anti-counterfeiting principle:
[0044] 1: First, before all anti-counterfeiting labels leave the factory, for each anti-counterfeiting label, the two endpoints on the anti-counterfeiting strip 3 are captured by a camera, and the two points are connected to form a measuring line. At this time, the long side of the limit frame strip 4 is selected as the reference line, and the angles between each measuring line and the reference line are measured. The values of these angles are arranged from small to large into a sequence B, and this data is stored in the local anti-counterfeiting database of the corresponding anti-counterfeiting label.
[0045] 2. After purchasing the product, the consumer first scrapes off the silver layer 6, and then uses an image acquisition device, preferably a mobile phone in this embodiment, that is, through the scanning function of the mobile phone, to capture the two endpoints on each anti-counterfeiting strip 3, and connect the two points to form a measuring line; and automatically select the long side of the limit frame strip 4 as the reference line, measure the angle between each measuring line and the reference line, and arrange all the angles from small to large into a series A.
[0046] Three: Compare sequence A with the corresponding data (sequence B) in the background anti-counterfeiting database. If sequence A matches the corresponding data (sequence B) in the background anti-counterfeiting database, the word "authentic" will pop up on the mobile phone screen; if not, calculate the absolute difference a of each corresponding value in sequence A and sequence B. If 0≤a<10, the word "authentic" will pop up on the mobile phone screen; if a≥10, a voice alarm will be issued through the mobile phone. Giving each data value an error tolerance of 0~10 can reduce the numerical deviation caused by the shooting angle of consumers, thereby reducing unnecessary false alarms. Moreover, since there are multiple anti-counterfeiting strips 3 on one anti-counterfeiting label, the error tolerance is only between 0~10. Therefore, the anti-counterfeiting ability will not decrease too much in general, which fully balances the anti-counterfeiting ability and query difficulty.
[0047] Embodiment 2: An anti-counterfeiting label, which is different from Embodiment 1 in that the anti-counterfeiting strip 3 is made of metal. The anti-counterfeiting strip 3 made of metal has the characteristics of high strength, good surface quality, good texture, and not easy to break, so it can be used on high-end anti-counterfeiting labels, suitable for square tea cans, hardcover books and other products.
[0048] Embodiment 3: An anti-counterfeiting label, which is different from Embodiment 1 in that the anti-counterfeiting strip 3 is made of plastic. The anti-counterfeiting label made of plastic has good corrosion resistance and moisture resistance, and can ensure that its shape does not change in a humid environment. Therefore, it has strong anti-interference ability, which is beneficial to improving the stability of anti-counterfeiting information and is suitable for areas with humid air all year round.
[0049] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
