Abstract: With the development of related information science and technology and the gradual improvement of people’s awareness of security and privacy in recent years, enterprises begin to hope to design effective and convenient anti-counterfeiting technology to safeguard their own interests, but there are still many problems in the anti-counterfeiting technology on the market at present. This system makes full use of the blockchain technology to realize the traceability of commodities, at the same time, it combines NFC technology and Chinese cryptographic algorithm to provide a unified and convenient anti-counterfeiting management system for enterprises. And consumers can identify the authenticity of commodities through mobile APP, and can also see the whole data chain of commodities from production to sale through blockchain system. The whole system is very convenient to deploy and use. It can be directly applied to the anti-counterfeiting industry to solve the anti-counterfeiting problems, and it has a very strong practicability.
Keywords: blockchain; Chinese cryptographic algorithm; NFC anti-counterfeiting; SN code; mobile APP
