A Consortium Blockchain-Based Information Management System For Unmanned Vehicle Logistics

Unmanned vehicle (UDV) delivery technology can meet the special needs of users and realize efficient and flexible distribution of logistics orders. However, there are risks of order data leakage and tampering in the intelligent logistics distribution environment. To solve this problem, this paper designs and implements a system based on the Hyperledger Fabric blockchain platform. Based on the blockchain technology, the system adopts a distributed architecture to establish a secure and trustworthy logistics data management platform to achieve the integrity and traceability of data in the logistics process. The data dual-chain storage strategy is used to ensure the efficiency of data queries. Furthermore, four smart contracts including order management contract (OMC), access control management contract (ACC), access control policy management contract (ACPC), and environmental data management contract (EDC) are designed in combination with the attribute-based access control strategy. By triggering the smart contract, the controllable access of order data can be realized. Finally, two groups of experiments are designed to test the performance of the system. Experimental results show that the proposed system can maintain high throughput in a large-scale request environment under the premise of ensuring data security.
