A Regulated Anticounterfeiting Traceability Metamodel Based on Blockchain in Supply Chain in the Era of IR 4.0

Abstract

In order to solve the problems of information island, information tampering and forgery, and information asymmetry between enterprises and consumers in the supply chain and to improve the efficiency of the whole system and realize the interconnection and effective supervision of supply chain information, the typical links of supply chain supervision system based on blockchain are abstracted through the comprehensive analysis of supply chain business processes and data characteristics. A regulatory anticounterfeiting traceability metamodel based on blockchain in the supply chain is constructed. Combined with the data of the supply chain system of a rice processing enterprise, a case study is carried out. The anticounterfeiting and traceability supervision metamodel based on the blockchain can be well applied to the rice supply chain system; solve the problems of data privacy encryption, secure storage, and authority management in the rice supply chain; and realize the interconnection and effective supervision of supply chain information. For enterprises in different positions in the supply chain, a unified anticounterfeiting traceability platform is established through the model, which can provide security and privacy protection for all kinds of enterprise data at the same time; for consumers, the model meets the security and traceability of each data of purchasing goods and ensures the integrity and authenticity of the data. The research content of this paper can provide a practical application solution for supply chain security supervision.
