Leveraging the Internet of Vehicles (IoV) to accurately and timely disseminate traffic information, especially for emergency information, is an important way to improve traffic safety and efficiency. However, privacy and security issues in the information transmission process will seriously affect the reliability of the information dissemination system. In this paper, we propose a decentralized targeted information dissemination framework in vehicular networks based on blockchain techniques. In this framework, the information collected by users is uniformly judged and identified by Roadside Units (RSUs), and finally packaged and uploaded to the blockchain that makes the system run more stable and reliable. Further more, we utilize reputation evaluation algorithm to comprehensively process the collected information, and we design the corresponding reputation management system to stimulate more users to participate in the system and provide as accurate information as possible. Extensive simulation results reveal that the proposed framework is effective and feasible in collecting, filtering, conducting, and disseminating in vehicular networks.
