Consideration on Data Conformance Toward Building Trust in Supply Chain

The new threats and risks to supply chains are increasing, and countermeasures to these threats are required. In Cross-ministerial Strategic Innovation Promotion Program (SIP) "Cyber Physical Security for IoT Society", a framework to enhance the trustworthiness of the supply chain is considered. In this paper, we focus on the data transmitted between organisations and propose a framework to enhance the trustworthiness of data supply chain by validating the conformance of its management and usage. The framework consists of 1) profile that defines the requirements of data management and usage, 2) conformance validation logic that ensures that the management and usage comply with the profile and 3) Trust Store that manages results of validation results through the entire supply chain.
