摘要

A data management server (60) is configured to manage a trading record (ReT) between traders (TR) that form a supply chain (SC). The data management server (60) is configured to acquire item data attached to a delivered item (IMi) delivered to a specific entity (TRs) and company data assigned to the specific entity, and calculate a hash value based on the item data and the company data. The hash value is provided to the specific entity (TRs) as the item data to be attached to a shipped item (IMo) shipped from the specific trader (TRs) to another trader (TR).
