A privacy-protected alliance taxi-hailing method and system

Abstract

A privacy-protected alliance taxi-hailing method and system, belonging to the technical fields of anonymous authentication, privacy protection and block chain. Including multiple car-hailing cloud service providers sharing user data components. Alliance taxi-hailing platform. Passengers send alliance taxi-hailing requests to roadside nodes. Roadside nodes verify passengers' identities and data, broadcast the request in their own coverage area, and receive the broadcast The driver sends the alliance taxi response to the road node; the roadside node verifies the driver's identity and data, and sends the matching driver information to the corresponding passenger; after the passenger contacts the driver, sends a confirmation message to the roadside node, and the alliance taxi starts, and the passenger sends Drivers pay fares anonymously; roadside nodes maintain the consortium blockchain. The taxi-hailing method and system provide timely taxi-hailing services for passengers, provide commercial benefits for cloud service providers, protect user privacy and commercial secrets of cloud service providers, and reduce computing and communication overheads on the basis of existing protocols.

Description

technical field [0001] The invention relates to a privacy-protected alliance taxi-hailing method and system, and belongs to the technical fields of anonymous authentication, privacy protection and blockchain. Background technique [0002] Using the real-name method to submit taxi-hailing services, although practicality can be guaranteed, will expose the privacy of users, mainly passengers and drivers. Therefore, in recent years, there have been multiple privacy-protected taxi-hailing methods. The privacy-protected taxi-hailing method generally includes four participants: passenger (Rider), driver (Driver), cloud service provider (Service Provider) and certificate issuance center (Certificate Authority); among them, passengers want to obtain taxi-hailing services, and drivers provide taxi-hailing services. Service, the cloud service provider is the platform that provides taxi services, and the certificate issuance center is the user registration authority. [0003] The spec...

Problems solved by technology

However, in this scenario, not only the user has privacy that needs to be protected, including identity, location of the car, taxi conditions, and destination, but the cloud service provider also has its own business secrets that need to be protected, such as when Didi’s driver has been in a certain area. If there are no Uber passengers on the inner streets, Didi will know that there are not enough drivers for Uber in this area, so it can call more drivers to this area to occupy the market; The standards for obtaining commissions in taxi rides are public. If the identities of cloud service providers are not protected, the commissions they get from alliance taxis every time will also be calculated, thus exposing their profits in alliance taxis. This exposes their trade secrets
