Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of label, in particular to a multistage anti -fake two -dimensional code label. BACKGROUND

[0002] With the popularity of smart phones, users need to complete self-authentication in a short time in many scenarios. However, the existing self-authentication scheme usually has structural defects. As a widely used solution, although the color two-dimensional code label improves the visual recognition and information carrying dimension through color zoning, it still belongs to the category of digital images that can be copied. Attackers can capture the color matrix and encoding logic completely through high-precision scanning equipment, realize digital cloning, and cause the anti-fake system to be systematically bypassed.

[0003] In view of this defect, physical anti-copy special code technology (such as microtext, invisible ink, etc.) has emerged. Such technology has material characteristics that cannot be digitally copied, and can theoretically effectively resist batch counterfeiting. However, in actual use, there are obvious problems: special codes need to rely on specific professional inspection means, and when there is a lack of explicit interactive guidance in the consumer scene, ordinary users are difficult to quickly locate the anti-fake unit in the complex packaging of the commodity, and it is even more difficult to independently determine whether the physical code body or the digital label should be scanned. UTILITY MODEL CONTENT

[0005] In the first aspect, the utility model provides a multistage anti-fake two-dimensional code label, which comprises a color code area layer and a shape pattern layer; the color code area layer is printed with a color two-dimensional code image; the shape pattern layer is arranged above the color code area layer and is printed with a black dot matrix shape pattern, the black dot matrix shape pattern is a shape pattern filled with unit black dot matrix, and the black dot matrix shape pattern is located in the color two-dimensional code image.

[0024] like Figure 1 As shown, in one embodiment, the multi-level anti-counterfeiting QR code label of this utility model includes a color code area layer 1 and a shape pattern layer 2.

[0025] The color code layer 1 is printed with a color QR code image. The color QR code image comprises multiple regions, each filled with a different color. Preferably, the multiple regions are of the same size.

[0026] The shape pattern layer 2 is disposed above the color code area layer 1 and is printed with a black dot matrix shape pattern. The black dot matrix shape pattern is a shape pattern filled with unit black dot matrices and is located within the color QR code image. Each unit black dot matrix refers to a complete and identifiable black dot matrix functional unit. The black dot matrix shape pattern can be one of a circle, triangle, parallelogram, rhombus, or regular polygon. Preferably, the black dot matrix shape pattern is embedded within the color QR code image at its maximum size. For example, when the black dot matrix shape pattern is a circle, the distances between the endpoints of the circle in the up, down, left, and right directions and the top, bottom, left, and right boundaries of the color QR code image are all within 1 mm. When the black dot matrix shape pattern is a triangle, the distances between the endpoints of the triangle in the up, down, left, and right directions and the top, bottom, left, and right boundaries of the color QR code image are all within 1 mm. Furthermore, the black dot matrix shape pattern contains at least one identifiable unit black dot matrix, thereby allowing the acquisition of corresponding information through the unit black dot matrix. Figure 2 The image shows various black dot matrix patterns.

[0027] like Figure 3As shown, the color two-dimensional code image in the multi-level anti-counterfeiting two-dimensional code label comprises four regions. The colors adopted by the four regions are blue, green, red and yellow. In order to ensure that the color two-dimensional code image can be read, the selected blue, green, red and yellow colors should not be too deep or too light. The brightness range of the four colors is 20% to 80%. Preferably, the CMYK value of the blue color used in the utility model is (70, 0, 0, 0), the CMYK value of the green color is (60, 0, 90, 0), the CMYK value of the red color is (0, 50, 50, 0), and the CMYK value of the yellow color is (0, 40, 90, 0).

[0028] As Figure 4 shown, in an embodiment, the multi-level anti-counterfeiting two-dimensional code label of the utility model further comprises a substrate layer 3. The substrate layer 3 is arranged below the color code area layer 1 and is used to carry the color code area layer 1 and the shape pattern layer 2. Among them, the substrate layer 3 can adopt a paper substrate layer, a plastic substrate layer, a metal substrate layer and a glass substrate layer, so as to meet the application of the multi-level anti-counterfeiting two-dimensional code label in different application scenarios.

[0029] In an embodiment, the multi-level anti-counterfeiting two-dimensional code label of the utility model is generated as follows.

[0030] Firstly, a black two-dimensional code image is generated based on a randomly generated anti-counterfeiting code (such as a character sequence composed of letters and numbers) and text information such as a website link to be recorded. By scanning the black two-dimensional code image, the text content composed of the anti-counterfeiting code and the text information can be obtained. Then, the corresponding color arrangement code is obtained according to the text content. Different color arrangement codes correspond to different color arrangements. According to the color arrangement, different regions of the black two-dimensional code image are colored, and a color two-dimensional code image is obtained.

[0031] For example, the black two-dimensional code image is divided into four equal regions and arranged in the order from top to bottom and from left to right. When the colors adopted are blue, green, red and yellow, the corresponding color codes are 1, 2, 3 and 4 respectively. Then when the color arrangement code is 4213, the colors of the four regions are yellow, green, blue and red according to the preset region arrangement order.

[0032] Then, a shape code is generated according to the text content. Different shape codes correspond to different shape patterns, such as a circle, a triangle, a parallelogram, a diamond, a regular polygon, etc. A shape pattern with a size not greater than that of the color two-dimensional code image is obtained according to the shape code. Then, a unit black dot matrix is generated according to the text content, and the unit black dot matrix is used to fill the shape pattern to obtain a black dot matrix shape pattern of the black dot matrix. Finally, the black dot matrix shape pattern is superimposed on the color two-dimensional code image to obtain the multi-level anti-counterfeiting two-dimensional code label.

[0033] In actual use, when a user scans the multi-level anti-counterfeiting two-dimensional code label by using a scanning device, corresponding text information is obtained through the color two-dimensional code image first. The scanning device obtains a corresponding color arrangement code, a shape code, and a unit black dot matrix according to the text information. If the color arrangement code, the shape code, and the unit black dot matrix are inconsistent with any one of the actual color arrangement, the shape pattern, and the unit black dot matrix of the multi-level anti-counterfeiting two-dimensional code label, it can be determined that the multi-level anti-counterfeiting two-dimensional code label is a counterfeit two-dimensional code label, so that accurate anti-counterfeiting verification is realized.

[0034] Therefore, the multi-level anti-counterfeiting two-dimensional code label of the utility model transcends the limitation of the traditional color two-dimensional code which simply relies on color information. By introducing a "stacked geometric shape logic code" (such as a specific microstructure and a random distribution feature), the core anti-counterfeiting element of the label cannot be completely captured and digitally cloned by a high-precision scanning device, which blocks the vulnerability of systematic digital copying by attackers and greatly improves the essential safety of the anti-counterfeiting system. The information association mechanism is designed ingeniously, which effectively avoids the fatal shortcoming of a pure physical special code (such as a microtext and invisible ink). Users only need to scan the explicit and easily identifiable digital color four-zone two-dimensional code part on the label by using a smart phone, without having to search for a hidden physical code body or use any professional equipment or complex operation. In the familiar code scanning process, a clear authenticity determination result can be obtained quickly and intuitively, which perfectly meets the strong demand of users in the smart phone era for "self-determination and fast verification". The design essence of the multi-level anti-counterfeiting two-dimensional code label lies in the strong logical binding of a physical anti-counterfeiting layer (stacked geometric shape logic code, providing uncopyable safety) and a digital interaction layer (color four-zone two-dimensional code, providing a user-friendly entrance and information bearing). This architecture creatively establishes a stable technical balance point between "high anti-counterfeiting strength" (depending on physical uncopyability) and "high user friendliness" (depending on standardized digital interaction), which not only has the anti-copying barrier of physical anti-counterfeiting technology, but also inherits the convenience and popularity of digital two-dimensional codes.

[0035] The above embodiments only exemplarily illustrate the principles and effects of the present application, and are not used to limit the present application. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of the present application. Therefore, all equivalent modifications or changes completed by those skilled in the art without departing from the spirit and technical thought disclosed by the present application should be covered by the claims of the present application.
