AI Technical Summary

Technical Problem

There are problems with insufficient privacy protection and low algorithm efficiency in the intelligent perception of the Internet of Vehicles, especially under the conditions of vehicle mobility and high latency requirements, it is difficult to achieve effective data privacy protection.

Method used

A blockchain-based privacy-preserving data collection method is adopted, which assigns temporary serial numbers to vehicles through roadside units (RSUs), uses pseudo-random functions to generate noise and combines it with asymmetric encryption technology to achieve data and identity privacy protection. At the same time, data transmission is optimized by determining the transmission rounds to reduce computation and communication overhead.

Benefits of technology

It achieves connectionless and complete privacy protection of vehicle data, improves the utilization rate of communication resources, reduces computing and communication overhead, and meets the privacy protection requirements of intelligent perception in the Internet of Vehicles.

Abstract

The application provides a blockchain-based privacy protection data collection method in Internet of Vehicles crowd-sourced perception, which comprises the following steps: sending a request task to a target vehicle group through a roadside unit (RSU); collecting data by the target vehicle group according to the request task; calculating a sending round according to the size of the collected data by the RSU, and sending the size of the collected data and the sending round to the target vehicle group; sending encrypted collected data to the RSU by the target vehicle group according to the size of the collected data and the sending round; and uploading the encrypted collected data to a blockchain by the RSU. The method provided by the application realizes privacy protection in the Internet of Vehicles crowd-sourced perception task.
