Embodiment 1

[0044] see figure 1 , the present invention provides a technical solution: a blockchain-based user privacy protection scheme for car-hailing, including the following:

[0045] TA initializes the entire car-hailing system; passengers, drivers and roadside nodes register with TA to obtain corresponding keys; passengers send car-hailing requests to the nearest roadside node; roadside nodes and drivers respond to passengers' car-hailing requests; The roadside node matches the driver for the passenger, and returns the matching information to the corresponding passenger and driver; the successfully matched passenger and driver send a confirmation message to the roadside node, start the trip, and send the car-hailing record to the district after the trip ends. blockchain network.

[0046] Specifically, it is realized through the following process:

[0047] 1. System initialization: TA selects security parameters and generates system parameters:

[0048]TA selects the security para...

Abstract

The invention relates to a user privacy protection scheme for car hailing based on a blockchain, and belongs to the technical field of communication of the Internet of Vehicles. The user privacy protection scheme includes the steps: a TA initializes a whole car-hailing system; a passenger, a driver and a roadside node register to the TA to obtain corresponding secret keys; the passenger sends a car hailing request to the nearest roadside node; the roadside node and the driver respond to the car hailing request of the passenger; the roadside nodes match drivers for the passengers and return successfully matched information to the corresponding passengers and drivers; and the passenger and the driver which are successfully matched send confirmation information to the roadside node to start ajourney, and after the journey is finished, the car hailing record is sent to the roadside node, and the roadside node sends car hailing data to the cloud server to be stored and sends a car hailingdata signature to the blockchain network. Compared with the prior art, the identity privacy, the position privacy and the request / report privacy of the user can be protected; rapid matching between passengers and drivers is realized; and a data auditing function of the car-hailing data is realized by using the block chain.

Description

technical field [0001] The invention relates to a block chain-based user privacy protection scheme for car-hailing, and belongs to the field of communication technology of the Internet of Vehicles. Background technique [0002] The car-hailing system is an intelligent service system that slows down road traffic, especially during peak transportation periods and when the number of taxis is insufficient, the role of ride-hailing is more prominent. At the same time, car-hailing also has many positive social and environmental benefits. During the car-hailing process, passengers and drivers send their car-hailing requests and car-hailing responses to a car-hailing system, and wait for the system to match them with suitable users. [0003] However, ride-hailing data (including passengers' ride-hailing requests and drivers' ride-hailing responses) is location-dependent. If the car-hailing data is not protected, the user's personal information (including home address, work address...
