Efficiently and safely sharing data in the Internet of vehicles (IOV) is of great significance to the development of intelligent transportation. To combine with blockchain has great potential in promoting the extent of sharing and privacy for IOV, however, there still exists a problem how to ensure its safety. From the perspective of solving the problem, this paper systematically arranges and analyzes the latest researches on the integration and implementation of blockchain of data sharing with IOV. Firstly, it summarizes the traditional vehicle networking data sharing model and analyzes its characteristics. Secondly, it introduces the current situation of data secure sharing of IOV based on blockchain from six aspects, including the reliability of sharing data, the security of sharing data, incentive mechanism, access control, scalability and storage mode. Thirdly, it lists and analyzes the characteristics of three general models for secure data sharing of IOV based on blockchain. Finally, it discusses the directions of future research and the development of this field, and presents feasible solutions to solve the security problem of data sharing in IOV, so as to provide theoretical support for the construction of data sharing in the future Internet of vehicles.
