(English Abstract) |
In the pharmaceutical supply chain (PSC), the process of transporting medicines is a critical process as it requires continuous monitoring of temperature-controlled products. Any deviation in the temperature may make the medicine or vaccination hazardous for consumption by patients. Hence, a tracking solution is required that enables the participating entities in the PSC to acquire information about medicines condition during transportation. In this regard, provenance plays a key role in maintaining lineage information about product phases as it evolves throughout the supply chain (SC). In this paper, we propose a provenance-based solution to maintain and monitor a complete log of sensor data along with supporting provenance information whenever required. We use IOTA distributed ledger technology (DLT) to share data transparently among all participating entities. Furthermore, we use the Masked Authenticated Messaging (MAM) protocol to facilitate data confidentially, data integrity, and restricted data accessibility. Finally, we evaluate the proposed approach in terms of attaching and retrieving sensor data along with provenance information at different time intervals. |
