Automobiles Driving Data Recording Method Based on Internet of Vehicles and Blockchain Technologies

This paper proposes a method to record automobiles driving data by using Internet of Vehicles (IoV) and blockchain technologies. The automobiles physical driving data are collected from On-Board Diagnostics (OBD) or J1939 through IoV, whereas the blockchain used in paper is built by the use of Hyperledger Fabric and RSA digital signature. The proposed method could solve the major issues of verification whether the forged data enters the blockchain. The proposed Internet of Vehicles data transmission is to record driving operation data every second, and upload driving data through smart contract (Chaincode) automation to ensure the correctness, integrity and immediacy of the blockchain content of driving data. The blockchain platform uses practical Byzantine Fault Tolerance (PBFT) consensus mechanism, PBFT has fault tolerance, and effectively improves the blockchain transaction volume per second (Transactions Per Second, TPS). Finally, through Hyperledger Explorer monitoring the blockchain status and Hyperledger Caliper performance test, the experimental results show that the proposed method could effectively solve the false data entering the blockchain. The proposed method can be applied to practical application services such as highway passenger transport management, financial technology and Usage-Based Insurance (UBI) in the future.
