Commodity anti-counterfeiting method and device

Abstract

The embodiment of the invention discloses a commodity anti-counterfeiting method and a device. The method comprises the following steps of generating the public key and the private key of a commodity; storing the hash values of the serial number, the public key and the private key of the commodity and the circulation data of the commodity in a common database by using a block chain; upon receiving the verification information of the public key of the commodity and determining the stored state of the public key in the common database, determining the first legal sales state of the commodity according to the serial number and the circulation data of the commodity, and marking the state of the commodity to be sold out; upon receiving the verification information of the secret key of the commodity and determining the stored state of the public key corresponding to the secret key in the common database, determining the first legal verification state of the commodity according to the serial number and the circulation data of the commodity, and marking the state of the commodity to be verified. Through preparing the public key and the private key of the commodity into special two-dimension codes and pasting the special two-dimension codes onto the outer package and the surface of the commodity, the readability, the verifiability and the binding performance of anti-counterfeiting marks are ensured. Meanwhile, by means of the block chain, the commodity circulation traceability and the commodity source uniqueness are ensured. At the same time, the cost is reduced.

Description

technical field [0001] The embodiments of the present invention relate to the field of computer technology, and in particular to a commodity anti-counterfeiting method and device. Background technique [0002] Common anti-counterfeiting technologies at home and abroad include printing anti-counterfeiting, chemical material anti-counterfeiting, physical anti-counterfeiting, digital technology and information anti-counterfeiting, packaging destructive structure anti-counterfeiting and biometric anti-counterfeiting, etc. The purpose of these technologies is to create an anti-counterfeiting commodity identification, But so far, all these technologies have only partially solved the uniqueness, readability, verifiability and binding properties of the protected goods required in the anti-counterfeiting label. Articles are unable to achieve low-cost anti-counterfeiting. [0003] The shortcoming and deficiency of these anti-counterfeiting technologies are described as follows: [0...

AI Technical Summary

Problems solved by technology

[0004] The uniqueness of anti-counterfeiting marks: Most of the anti-counterfeiting marks of commodities are due to the complex processing technology, advanced production technology and confidentiality, which lead to high anti-counterfeiting costs and make counterfeiters stop. The level is higher than the genuine product, so that the anti-counterfeiting manufacturers themselves cannot distinguish

In addition, due to the complexity of the production process, anti-counterfeiting can only be produced by professional anti-counterfeiting companies. Due to the possibility of internal crimes, the uniqueness of anti-counterfeiting marks cannot be guaranteed objectively.

[0005] Readability and verifiability of anti-counterfeiting marks: Some anti-counterfeiting products use natural textures and physical properties of materials to create unique marks, but they cannot be read, or the reading is complicated, resulting in expensive reading equipment and cannot be popularized.

[0006] Secondly, after the anti-counterfeiting identification data is read, one verification method is to compare it with the manufacturer’s commodity database data. However, once the verification database is leaked or privately tamper-proof (based on the fact that the manufacturer is a stakeholder in the anti-counterfeiting ecology), the verification result will not Doesn't adequately prove the authenticity of the product, so this method of verification is unfair

Another way is to judge by presetting the threshold set by the anti-counterfeiting manufacturer in the verification device. This method can only do universal verification because it does not involve the characteristics of a single product. If the threshold is too high, it will filter out genuine products. If the product is too low, there is a possibility of counterfeiting. What's worse, it is impossible to prevent internal crimes committed by anti-counterfeiting manufacturers.

[0007] Bindability of anti-counterfeit marks and protected goods: At present, anti-counterfeit marks are either pasted on the internal packaging of the goods (or integrated with the product packaging), or physically fixed on the goods as part of the goods; therefore, all Anti-counterfeiting marks, unless one-time use anti-counterfeiting marks, can be violently separated from the product itself, which cannot solve the problem of repeated use

[0008] High cost of anti-counterfeiting: due to the fact that the anti-counterfeiting marks cannot be guaranteed to be unique, the verification data cannot be fair, and the anti-counterfeiting marks can be reused, etc., the above-mentioned anti-counterfeiting technologies are only a fuss about anti-counterfeiting, but none of them can fight against counterfeiting. Seriously, in real life, the anti-counterfeiting label has actually become a magic weapon for manufacturers to avoid the responsibility of counterfeit goods, and all consequences can only be borne by consumers

[0009] High anti-counterfeiting cost: The higher the anti-counterfeiting technology, the stricter the internal management requirements. In addition to the cost of the anti-counterfeiting technology itself, the internal management cost increases exponentially. Therefore, anti-counterfeiting products with higher technology are less suitable for large-scale promotion

[0010] Unity of anti-counterfeiting subject: The current anti-counterfeiting method relies solely on the strength of the manufacturer, and it is the enterprise's own strength to fight against the entire disordered, money-oriented, and lack of integrity society, often unable to do what it wants
