Anti-counterfeiting annular code and encoding method thereof

Abstract

The invention provides an anti-counterfeiting annular code and an encoding method thereof. The annular code expresses a number and letter string by a plurality of concentric rings; each concentric ring consists of full lines with unequal lengths and gaps; the number and letter string of the annular code is converted into a binary bit string through encryption; and a layer quantity of the annular code and a quantity of binary numbers in each layer can be determined according to the quantity of the binary bit strings. With the adoption of the anti-counterfeiting annular code provided by the invention, the anti-countering degree is greatly improved, so that not only can an anti-counterfeiting sequence code be difficult to obtain, but also the technical difficulty that a label in an annular code structure is formed is overcome. Therefore, the reliability of the annular code is greatly improved. The annular code has the advantages of low cost, and convenience and rapidness of searching.

Description

technical field [0001] The invention relates to the technical field of digital anti-counterfeiting, in particular to a method for making an anti-counterfeiting ring code. Background technique [0002] With the development of society and the improvement of productivity, the objects of society are becoming more and more abundant. At the same time, a large number of counterfeit and counterfeit products have also emerged, especially fake famous products, such as fake famous cigarettes, fake famous wine, fake famous bags, etc., flooding the market, seriously damaging the interests of consumers and genuine manufacturers and merchants. [0003] For this reason, some anti-counterfeiting verification measures and means have also appeared in the prior art, such as anti-counterfeiting printing, simple electronic tag (RFID) anti-counterfeiting identification, anti-counterfeiting code combined with background short message query system and the like. To a certain extent, these anti-count...

AI Technical Summary

Problems solved by technology

However, there are some defects and deficiencies: anti-counterfeiting at the simple physical structure level such as anti-counterfeiting printing is easy to be cracked and further counterfeiting is followed; the use of simple electronic tags and short message anti-counterfeiting query systems still lacks security considerations, and it is difficult to fully realize the authenticity. In the sense of effective anti-counterfeiting verification, the reliability is not high
