Embodiment Construction
[0042] The specific embodiments of the present invention are described below so that those skilled in the art can understand the present invention, but it should be clear that the present invention is not limited to the scope of the specific embodiments. For those of ordinary skill in the art, as long as various changes Within the spirit and scope of the present invention defined and determined by the appended claims, these changes are obvious, and all inventions and creations using the concept of the present invention are included in the protection list.
[0043] like figure 1 As shown, the realization of the car networking privacy protection method based on crowdsourcing applications includes the following steps:
[0044] S1. When the target vehicle U detects that it occurs at position l 0 The traffic data Msg(l 0 ), determine the traffic data Msg(l 0 ) time tolerance factor;
[0045] S2. Obtain the time tolerance range according to the time tolerance coefficient. Within...

The invention discloses a privacy protection method for Internet of Vehicles based on crowdsourcing applications, which includes the following steps: S1, determining the time tolerance coefficient; S2, selecting one of p vehicles and uploading the traffic data to the edge as a group Node; S3, and the user's request location l r Blur the POI at the corresponding position lr Middle; S4, constructing a set of normal distribution functions by difference; S5, obtaining the offset probability; S6, selecting k-1 position points according to the maximization of the offset probability entropy; S7, sending the k position points to the edge node, and obtaining the corresponding k pieces of traffic data; S8, the target vehicle U according to the position point POI lr Select the required traffic data from the obtained k pieces of traffic data at the position in the request data, and complete the traffic data download in the Internet of Vehicles. The invention can effectively protect the privacy in the process of uploading and downloading the Internet of Vehicles data.
Description
technical field [0001] The invention relates to the utilization of privacy protection of the Internet of Vehicles, in particular to a privacy protection method for the Internet of Vehicles based on crowdsourcing applications. Background technique [0002] Connected Vehicles are generally equipped with smart devices, such as high-definition cameras, driving recorders, communication devices, and other sensors, to provide driving safety and reduce traffic accidents. Due to the continuous increase in the number of connected vehicles, crowdsourcing applications have also appeared in large numbers in the Internet of Vehicles. In crowdsourcing applications, vehicles actively collect traffic or safety information, such as road maps, traffic accidents, and vehicle congestion. This is different from the traditional collection method, which requires specialized equipment and dedicated people to do these tedious tasks, which requires a lot of manpower, material and financial resources....
