Embodiment 1

[0057] figure 1 It is the original plan view of the current QR code.

[0058] like figure 2 shown in figure 1 In the blank space of the original version of the current QR code, insert ( figure 1 There are only 16 isolated ink dots 1 in the current original version of the two-dimensional code, which is not enough to meet the requirements, so some isolated ink dots 1 with a width (or diameter) of 0.6-0.8 mm need to be inserted from the outside of the body. The number of isolated ink dots 1 inherent in the original version of the two-dimensional code plus the number of inserted isolated ink dots 1, the cumulative total n is preferably greater than 12, or 24, or 36, or 48, or 60, or 72 , or 80, or 92, or 100, or 200, or 300.

[0059] The code 2 printed on each printed matter 6 is preferably a unique two-dimensional code.

[0060] After the natural micro-diffusion of the ink (shrinkage should be understood as negative diffusion) to form sawtooth and cause the deformation of t...

Embodiment 2

[0066] figure 1 It is the original plan view of the current QR code.

[0067] like image 3 shown in figure 1 In the original version of the current two-dimensional code, the narrowest connection 3 of the three blank ink sticks is disconnected to separate some isolated ink dots 1, and the width of the isolated ink dots 1 is set to 0.8mm. In other words, some isolated ink dots 1 are separated from the disconnected wires of adjacent ink sticks. The number of isolated ink dots 1 inherent in the original version of the two-dimensional code plus the number of separated isolated ink dots 1, the cumulative total n is preferably 36-72.

[0068] The code 2 printed on each printed matter 6 is preferably a unique two-dimensional code.

[0069] After the natural micro-diffusion of the ink (shrinkage should be understood as negative diffusion) to form sawtooth and cause the deformation of the isolated ink dot 1, it is dried, cured, and shaped, and the two-dimensional code is enlarged a...

Embodiment 3

[0073] like Figure 4 As shown, combining the above two examples, in figure 1 Some isolated ink dots 1 are additionally inserted and printed in the blank gaps of the original version of the current QR code (in order to facilitate the readers to see and distinguish, the ink dots are represented by hanging nets in the figure, and there should be no hanging nets and no difference in actual implementation), and from The narrowest junctions 3 of the blank ink sticks on three sides are disconnected to separate some isolated ink dots 1 .

[0074] Other steps can be implemented in combination with the above two examples.

Abstract

The invention provides a high-precision sawtooth anti-counterfeiting method which comprises the steps that numerous isolated ink dots are set for codes, and the isolated ink dots are slightly diffused to generate sawtooth edges, deform and generate directionality; collecting and storing isolated point feature information in an anti-counterfeiting checking system database; matching the isolated point feature information with the filing information; and if the majority of isolated point feature information is consistent, the anti-counterfeiting checking system feeds back the information that the identification conclusion is true to the smart phone. Preprinting of the diffusant coating can be avoided, the sawtooth anti-counterfeit printing process can be simplified, the printing and manufacturing difficulty can be reduced, the identification conclusion accuracy can be improved, the revision trouble can be avoided, and the user experience can be improved.

Description

technical field [0001] The invention belongs to the field of information query anti-counterfeiting technology, and specifically relates to the improved technology of the applicant's own Chinese patent "Sawtooth anti-counterfeiting method for mobile phone identification code (CN104794629B)" - a high-precision sawtooth anti-counterfeiting method. Background technique [0002] The Chinese patent "Sawtooth anti-counterfeiting method for mobile phone identification code (CN104794629B)" authorized the applicant's anti-counterfeiting method, including printing codes or / and graphics on the substrate, so that the edges of the codes or / and graphics randomly generate personality Sawtooth edges; zoom in on the printed codes or / and graphics to obtain the zigzag feature information and codes; store the zigzag feature information and corresponding codes obtained by zooming in on the images and record them in the anti-counterfeiting inspection system database connected to the Internet The i...
