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] Such as 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. Wit...

The invention discloses an Internet of Vehicles privacy protection method based on crowdsourcing application. The method comprises the following steps: S1, determining a time tolerance coefficient; S2, selecting one vehicle from the p vehicles to upload the traffic data to an edge node in a group identity manner; S3, the request position lr of the user is blurred in the corresponding position point POIlr; S4, constructing a normal distribution function set by difference; S5, acquiring an offset probability; S6, selecting k-1 position points to the maximum extent according to the offset probability entropy; s7, sending the k position points to an edge node to obtain corresponding k parts of traffic data; and S8, the target vehicle U selects traffic data required by the target vehicle U fromthe obtained k parts of traffic data according to the position of the position point POIlr in the request data, and traffic data downloading in the Internet of Vehicles is completed. According to theinvention, the privacy in the uploading and downloading processes of the Internet of Vehicles data can be effectively protected.
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....
