Design Of Anti-counterfeiting System Based On Blockchain Technology

With the increase of shopping ways,there are more and more fake and shoddy products with imitation labels on the market,which not only damages the company's brand image,but also brings unnecessary damage to the market economy.And it also brings some doubts to people's shopping life,which seriously affects people's quality of life.At present,the anti-counterfeiting technologies on the market are mainly two-dimensional codes and RFID anti-counterfeiting labels.the factory information of the products are written into the anti-counterfeiting label for them,and use a custom anti-counterfeiting system to read the plain text and cooperate with the encryption algorithm for verification.In the end,anti-counterfeiting is achieved.However,most of encryption methods are single-item encryption technologies,and the encryption methods are relatively single,which is easy to be cracked by criminals.Moreover,the data management system is also centralized,and the product information is easily leaked.This way will lead to a large number of labels being copied,which will not achieve the purpose of anti-counterfeiting.The emergence of blockchain technology provides new ideas for anti-counterfeiting technology.Therefore,in this paper,a scheme is proposed that combines anti-counterfeiting technology with blockchain technology,which makes the data management system decentralized,and also enables the single encryption technology to be improved into a distributed encryption method.The advantages and disadvantages of RFID technology and distributed anti-counterfeiting technology are first introduced,and then the advantages of blockchain technology are introduced,which can be used to solve the problems of traditional anti-counterfeiting technology.Then according to the anti-counterfeiting requirements of the product,a detailed verification process analysis,verification scheme and security analysis are designed.Finally,based on the basic architecture of the blockchain: data layer,network layer,and consensus layer,an anti-counterfeiting system based on blockchain technology is designed,and the simulation tests are verified.The main innovations of this paper are as follows: The consensus mechanism(validation pool)of blockchain technology is used to solve the data centralization problem of the anti-counterfeiting system.The data is grouped in different schemes and combined with SM group encryption and cyclic shift encryption to improve the security of data transmission.In short,it is the combination of RFID technology and blockchaintechnology to greatly improve the anti-counterfeiting performance of the system.In the design process of this system,a distributed anti-counterfeiting system was designed based on the idea of distributed system of blockchain technology,called "A distributed anti-counterfeiting system and its method" and it was successfully accepted.
