Anti-counterfeiting two-dimensional code and anti-counterfeiting verification method thereof

Abstract

The invention relates to an anti-counterfeiting two-dimensional code and an anti-counterfeiting verification method, the anti-counterfeiting two-dimensional code comprises a substrate layer and a laser anti-counterfeiting label, an area of a two-dimensional code pattern is printed on the substrate layer, the two-dimensional code pattern comprises a plurality of cells which are adjacently arrangedend to end in sequence and form an annular two-dimensional code pattern, and the laser anti-counterfeiting label is matched with the cells in shape. The laser anti-counterfeiting label covers the surface of the local cell, so that corresponding anti-counterfeiting data information for anti-counterfeiting verification is obtained when the two-dimensional code pattern of the cell covered with the laser anti-counterfeiting label is scanned. The cells in the two-dimensional code pattern are shielded through the laser anti-counterfeiting label, and anti-counterfeiting data information can be formedaccording to different shielding parts of the laser anti-counterfeiting label, so that the anti-counterfeiting information is conveniently associated with product information, the two-dimensional code pattern has a relatively good anti-counterfeiting function, the two-dimensional code pattern is not conveniently and randomly copied, the technical problem that the two-dimensional code is easy to copy is solved with low cost, and the anti-counterfeiting two-dimensional code is suitable for large-area popularization and application.

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
