no. 1 approach

[0032] figure 1 The shown supply chain management system 100 according to the first embodiment of the present disclosure manages transaction records ReT of items traded between traders TR in a supply chain SC constructed including a plurality of traders TR. In the supply chain management system 100, for the purpose of preventing falsification of the transaction record ReT, the technology of the blockchain BC is used in the management of the transaction record ReT.

[0033] The supply chain SC is a connection between traders TR for delivering, for example, industrial products, agricultural products, and marine products to consumers CST. As an example, in a supply chain SC for delivering an industrial product to a consumer CST, material developers, material producers, processors, transporters, sellers, etc. are included in traders TR. In this case, the supply chain SC from the raw material MAT to the final product FP is constructed. In addition, in the present disclosure, the ...

no. 2 approach

[0149] Figure 13 as well as Figure 14 The illustrated second embodiment of the present disclosure is a modified example of the first embodiment. In the chain generation process based on the record generation program of the second embodiment (refer to Figure 13), the hash value of each trader TR and the issuance of item code QRi are omitted. In addition, in the record query processing based on the record reference program (refer to Figure 14 ), the transaction record ReT of the later process than the issue of the item code QRi is extracted together with the past transaction record ReT. Hereinafter, focusing on differences from the first embodiment, refer to figure 1 The chain generation processing and the record query processing of the second embodiment will be described.

[0150] During chain generation processing (refer to Figure 13 ), if the data management server 60 from the specific industry TRs (refer to figure 1 ) acquires project data and company data (refer...

no. 3 approach

[0165] The third embodiment of the present disclosure is another modified example of the first embodiment. The supply chain management system 100 of the third embodiment is designed on the premise that it coexists with other management systems that manage the supply chain SC. As an example, the other management system is a management system that does not use blockchain BC (hereinafter, old management system).

[0166] Corresponding to such a system configuration, the item code QRi of the third embodiment has both information used for management in the old management system and information (item data) used for management in the supply chain management system 100 . To describe in detail, in the two-dimensional code used as the item code QRi, a plurality of (two) areas for registering data are defined.

[0167] In one area (hereinafter, first area), information used in the old management system is recorded. As an example, in the first area, the format, data quantity, data body,...

Abstract

The invention provides a supply chain management method, a supply chain management program, a supply chain management system, and a transaction record display program. The data management server (60) manages a transaction record (ReT) between traders (TR) in a supply chain (SC) constructed by including a plurality of traders (TR). The data management server (60) acquires item data attached to a delivery item (IMi) delivered to a specific trader (TRs) and company data assigned to the specific trader (TRs), and calculates a hash value based on the item data and the company data. This hash value is provided to the specific trader (TRs) as item data attached to a shipping item (IMo) shipped from the specific trader (TRs) to another trader (TR).
