Abstract In recent years, with the continuous advancement of the intelligent process of
the Internet of Vehicles (IoV), the problem of privacy leakage in IoV has become
increasingly prominent. The research on the privacy protection of the IoV has become the
focus of the society. This paper analyzes the advantages and disadvantages of the existing
location privacy protection system structure and algorithms, proposes a privacy protection
system structure based on untrusted data collection server, and designs a vehicle location
acquisition algorithm based on a local differential privacy and game model. The algorithm
first meshes the road network space. Then, the dynamic… More >
