Anti-counterfeit Two-dimensional Code, Label and Application System Based on Fault Tolerance Mechanism

Abstract

The embodiment of the invention provides an anti-counterfeit two-dimensional code, a label and an application system based on a fault tolerance mechanism. Wherein, the anti-counterfeit two-dimensionalcode based on the fault tolerance mechanism comprises a carrier which can bear the anti-counterfeit two-dimensional code, a two-dimensional code body, a plurality of distributions which are randomlydispersed in the area of the two-dimensional code body and partially cover the two-dimensional code body; the anti-counterfeit two-dimensional code is formed according to the physical anti-counterfeitinformation formed by a plurality of distributors. Because of the random dispersion and the ability to partially cover multiple distributions, the anti-counterfeit information generated by each distribution is different, which solves the problem that the two-dimensional code is easy to be duplicated.

Description

technical field [0001] The invention relates to the anti-counterfeiting field of two-dimensional codes, in particular to an anti-counterfeiting two-dimensional code, a label and an application system based on a fault tolerance rate mechanism. Background technique [0002] Two-dimensional bar code / two-dimensional bar code (2-dimensional bar code) is a black and white graphic that is distributed on a plane (two-dimensional direction) according to certain rules to record data symbol information with a specific geometric figure. Corresponding geometric shapes represent text and numerical information, which can be automatically read by image input equipment or photoelectric scanning equipment to realize automatic information processing: two-dimensional codes provide more information storage capacity than bar codes, which is extremely convenient in the Internet age The people's daily life application. [0003] However, when the two-dimensional code is convenient for people to qui...

Problems solved by technology

[0003] However, when the two-dimensional code is convenient for people to quickly link to the designated website, there are often the following potential safety hazards: (1) It is very easy to manufacture and lacks anti-counterfeiting performance; because the two-dimensional code itself does not have anti-counterfeiting performance, anyone can prepare it Restricted two-dimensional code, and the user cannot identify the safety of the two-dimensional code through effective means. If the criminals cheat and scan the user, the user may be led into a trap by the criminals, causing property or even personal damage

(2) There is no authorization function for QR code access; that is, as long as there is a QR code for this link, no matter whether it is obtained through formal channels or illegally obtained, it can be linked to the specified content. In the absence of other review methods, the specified Content cannot be viewed only by authorized users

(3) The non-uniqueness of the two-dimensional code access, because the two-dimensional code can be easily manufactured, in theory, the same link can produce countless two-dimensional code patterns, but in actual production, each two-dimensional code pattern may be applied to On one product, countless products can be linked to the same QR code. If there are no other anti-counterfeiting measures, the possibility of this product information being counterfeited is very high, and there is no limit to the ability
