A color digital sequence two-dimensional code and its anti-counterfeiting method

Abstract

The invention discloses a color digital sequence two-dimensional code and an anti-counterfeiting method thereof. The color digital sequence two-dimensional code comprises a pattern region used for printing a two-dimensional code pattern. A code checking region for printing a two-dimensional serial number is arranged below the pattern region. The two-dimensional serial number is composed of a plurality of groups of numbers. Each group of the numbers is divided into a plurality of groups of numbers. The numbers in each group of numbers are printed in different colors, and then a color digital sequence is obtained. During anti-counterfeiting, a two-dimensional code is scanned by code scanning equipment. The scanned two-dimensional code is compared with a two-dimensional code and a color digital sequence pushed by a client, so that the authenticity thereof can be identified. If the scanned two-dimensional code and the two-dimensional code pushed by the client are not matched, the scanned two-dimensional code is identified to be fake. According to the technical scheme of the invention, the color two-dimension code serial number is printed under the two-dimensional code pattern, and the color sequence of the color two-dimensional code serial number is calculated based on the color sequence algorithm. Therefore, the style and the color digital sequence of a second two-dimensional code cannot be deduced based on a known two-dimensional code. Meanwhile, the problems that the two-dimension codes are copied in batches and cannot be distinguished in authenticity can be solved.

Description

technical field [0001] The invention belongs to the technical field of two-dimensional code anti-counterfeiting, and relates to a color number sequence two-dimensional code, in particular to a color number sequence two-dimensional code and an anti-counterfeiting method thereof. Background technique [0002] A two-dimensional code is a pattern of bars and spaces distributed on a plane according to certain rules to record data symbol information with a specific geometric figure. QR codes have the advantages of high reliability (reading accuracy far exceeds manual records), high efficiency (very fast reading speed, equivalent to 40 characters per second), etc. [0003] Wherein, the QR Code bar code is a kind of matrix two-dimensional bar code (the two-dimensional code referred to in the present invention is the QR Code bar code) developed by Japan Eenso Company, such as figure 1 As shown, in addition to the large information capacity and high reliability of two-dimensional bar...
