摘要

The safe and comfortable location based services are required for users in the internet of vehicles, at the same time, the privacy and confidential requirements are indispensable. Enciphering merely user's information cannot guarantee the safety of user's privacy, and the query itself may leak the user's location information and identity one. Aimed at the problem of privacy security in location based service under the internet of vehicles environment, in this paper, through analysis of LBS privacy security technology, in the V2I system of internet of vehicles, combining K area with fake names anonymous technology, a kind of improved PPA-IOV privacy protection algorithm is formed. Experimental verification indicated that the algorithm performs a higher anonymous success rate for users in the car network environment and reduced the average anonymous space, thus the service quality of user's query is improved.
