Abstract

The invention belongs to the technical field of Internet of Vehicles crowd sensing. The invention provides an Internet of Vehicles crowd sensing incentive method with a privacy protection characteristic based on blockchain, and aims to solve the problems that the privacy protection means of an existing Internet of Vehicles crowd sensing incentive method mostly depend on a third party, the hidden danger of privacy disclosure exists, and the problem of award distribution fairness is solved. According to the method, through an anonymous identity authentication mechanism, a winner selection mechanism for protecting privacy, a fairness-enhanced reward payment scheme and an intelligent contract, the problems of single-point faults, collusion attacks and the like existing in a centralized excitation method are solved; a lightweight privacy protection scheme without the assistance of a trusted third party is realized, and the vehicle identity and bidding privacy are protected; and the fairness of the bidder selection and reward allocation algorithm is enhanced.

Description

technical field

[0001] The invention belongs to the technical field of group intelligence perception of the Internet of Vehicles, and specifically relates to a method for stimulating the group intelligence perception of the Internet of Vehicles based on a block chain with privacy protection characteristics. Background technique

[0002] As urban populations grow, the number of cars starts to increase, which can lead to congestion on roads and parking lots. Intelligent transportation is a solution to make real-time control decisions for traffic efficiency and safety, which requires a large amount of traffic information. Today, vehicles have richer sensors, greater storage and communication capabilities, and the ability to collect and share data. The ubiquitous crowd-sensing technology has enabled the emergence of vehicle-connected crowd-sensing (VCS), a new paradigm that harnesses the power of vehicles to collect vast amounts of traffic-information perception data. When an ...
