An anti-counterfeiting two-dimensional code and its anti-counterfeiting verification method

Abstract

The invention relates to an anti-counterfeiting two-dimensional code and an anti-counterfeiting verification method. The anti-counterfeiting two-dimensional code includes a base layer and a laser anti-counterfeiting label. The base layer is printed with an area of ​​a two-dimensional code pattern. Set and form a cell with a circular two-dimensional code pattern, the laser anti-counterfeiting label matches the shape of the cell, and the laser anti-counterfeiting label is covered on the surface of some cells, so as to cover the two-dimensional code of the cell with the laser anti-counterfeiting label. When the pattern is scanned, the anti-counterfeiting data information corresponding to the anti-counterfeiting verification is obtained. In the invention, the cells in the two-dimensional code pattern are shielded by the laser anti-counterfeiting label, and the anti-counterfeiting data information can be formed according to different shielding parts of the laser anti-counterfeiting label, so that the anti-counterfeiting information can be easily associated with the product information, so that the two-dimensional code pattern has a better quality The anti-counterfeiting function of the QR code is inconvenient to copy the two-dimensional code pattern at will, and the low-cost solution solves the technical problem that the two-dimensional code is easy to be copied, which is suitable for large-scale promotion and use.

Description

technical field [0001] The invention relates to the technical field of two-dimensional codes, in particular to an anti-counterfeiting two-dimensional code and an anti-counterfeiting verification method thereof. Background technique [0002] A two-dimensional code refers to a barcode that expands another dimension and is readable on the basis of a one-dimensional code. It uses a specific geometric figure to record data symbol information in black and white graphics that are distributed on a plane according to certain rules. The device scans the QR code to obtain the information contained therein. Two-dimensional codes have the same advantages of low cost as one-dimensional codes. Moreover, compared with one-dimensional codes, two-dimensional codes can record more data and more complex data, such as pictures and network links. QR codes can be recognized by smartphones, and with the popularity of smartphones, it is easier to use. Because the two-dimensional code has the chara...

Problems solved by technology

At this stage, the two-dimensional code technology has been widely used in commodities, but the two-dimensional code as an image technology is relatively easy to be copied or counterfeited

At present, there are already some methods of adding anti-counterfeiting in the two-dimensional code, which are generally based on the anti-counterfeiting method of invalidation after querying, that is, the anti-counterfeiting information in the two-dimensional code can only be queried once, and the second query is considered to be an invalid query. The effect of the method is not strong. If the counterfeit goods use the copied unique code and check it before the genuine product query, this anti-counterfeiting can be invalidated, and this anti-counterfeiting is one-time, and it is impossible to judge whether the product is authentic or not again
