Anti-counterfeiting method

Abstract

Disclosed is an anti-counterfeiting method. A pattern is subjected to anti-counterfeiting treatment so that a unique security code is formed. The security code is composed of at least one arrayed security mark. The anti-counterfeiting method is characterized in that the security mark is composed of a group of M*N dot matrixes, both the letter M and the letter N are positive integers larger than or equal to 2, the dot matrixes include background dot sets, pattern effective point sets and anti-counterfeiting differential color point sets. On the basis, the anti-counterfeiting treatment includes centrally encoding and assigning the position and color of the anti-counterfeiting differential color points by an encoding algorithm, so that the anti-counterfeiting pattern with security marks is formed. The anti-counterfeiting method has the advantages that a brand-new anti-counterfeiting mode is designed, CPU encoding guarantees uniqueness of the anti-counterfeiting pattern, and the anti-counterfeiting effect is better.

Description

technical field [0001] The invention belongs to the technical field of anti-counterfeiting, and designs an anti-counterfeiting method, in particular a novel anti-counterfeiting pattern design method. Background technique [0002] Anti-counterfeiting technology refers to the measures taken to achieve the purpose of anti-counterfeiting. It can accurately identify the authenticity within a certain range and is not easy to be imitated and copied. Simply put, it is a technology to prevent counterfeiting and counterfeiting. It is a preventive technical measure adopted to protect the corporate brand, protect the market, and protect the legitimate rights and interests of consumers. [0003] At present, the more common article anti-counterfeiting technologies in the prior art are barcode technology and two-dimensional code technology. The barcode or two-dimensional code is read and analyzed by a supporting scanning device to obtain a code, and then the original code in the code and...

Problems solved by technology

[0004] However, these two anti-counterfeiting technologies also have defects. Defects: 1. The rules of barcodes and QR codes are all set, very easy to copy, and can be printed again in large quantities after reading

2. What is shown is not the actual content, and requires a certain printing accuracy to achieve recognition. It requires relatively sophisticated printing equipment, which cannot be produced with low resolution such as inkjet equipment
