Jie Wang, Le Zhang, Hongtao Li · Research Square · 2023
Abstract Drug safety is directly related to people’s health. With the development of logistics technology, ensuring drug circulation safety has become very important to ensure drug quality. In order to guarantee the security of the drug sources and circulation process, a blockchain-based scheme of secure traceability for drug is proposed in this work, which guarantees the security of trace- ability results through the de-trusting and traceability characteristics of blockchain technology, and optimizes the Internet sales of drugs.We adopt the idea of reverse search algorithm to reduce search time and improve search efficiency. Theoretical analysis and experimental results analy- sis show that this paper improves traceability efficiency and reduces search time while ensuring the security of traceability results.
