摘要:

粮油食品全供应链结构复杂、周转周期长、利益相关方众多,维护整个粮油食品供应链的安全具有挑战性,实现粮油食品全供应链信息安全可信溯源,有助于提高粮油食品质量安全,进而提升人民生活水平。本文以可信区块链和可信标识为驱动,构建粮油食品全供应链信息追溯模型,并进行合约化实现与实例验证。首先,在对粮油食品全供应链调研与分析的基础上,设计了适用于粮油食品的全供应链信息追溯模型框架。其次,分别设计了可信标识机制、多模存储机制和可信追溯机制。可信标识机制用于粮油食品全供应链的数据信息跟踪;多模存储机制用于解决粮油全供应链环节众多导致的信息繁多冗杂问题;可信追溯机制用于实现的粮油食品全供应链各环节信息采集、存储、传输的可信。最后,基于数据流转过程,进行了模型运行流程分析,并基于信息追溯模型,以超级账本Fabirc开源框架设计并研发了粮油食品可信追溯系统,通过案例对系统进行了实例验证。结果表明,本文构建的模型及系统解决了传统追溯机制及系统中存在的数据安全性低和共享性差的问题,实现了粮油食品供应链全生命周期多源异构信息的可信上链、存储、处理和追溯,提高了粮油食品追溯的细粒度和准确性,为粮食战略安全提供了一定的支撑。

Abstract:

The grain and oil food supply chain has a complex structure, long turnover cycles, and many stakeholders, so it’s challenging to maintain the security of this supply chain. A reliable traceability system for the whole grain and oil food supply chain will help to improve the quality and safety of these products, thus enhancing people’s living standards. Driven by the trusted blockchain and trusted identity concepts, this paper constructs an information traceability model for the whole grain and oil food supply chain, and describes how contract implementation and example verification are performed. First, an information traceability model framework of the whole grain and oil food supply chain is established based on the survey and analysis of grain and oil food supply chain. Second, trusted identification, multi-mode storage, and trusted traceability mechanisms are designed. The trusted identification mechanism is used to track the data information of the whole grain and oil food supply chain. The multimode storage mechanism solves the problem of miscellaneous information caused by many links in the whole grain and oil supply chain, while the credible traceability mechanism ensures the credibility of information collection, storage, and transmission. Finally, based on the data flow, the model operation process is analyzed. Using the information traceability model, the grain and oil food trusted traceability system is designed and developed with the Hyperledger Fabric open-source framework, and a case study is conducted to verify the system. The results show that the model and system constructed in this study solve the problems of low data security and poor sharing, which exist widely in the traditional traceability mechanism, and enable the trusted uplink, storage, processing, and traceability of multi-source heterogeneous information in the lifecycle of the whole grain and oil food supply chain. The proposed system improves the granularity and accuracy of grain and oil food traceability, and provides support for the strategic security of grain stocks.
