Keyless shared automobile system based on blockchain technology and construction method thereof

Abstract

The invention discloses a keyless shared automobile system based on a blockchain technology and a construction method thereof. The system comprises an application layer, a blockchain layer, a data storage layer and a physical layer; the application layer comprises a user management module, a vehicle management module and an order management module; the blockchain layer consists of several connected blocks, and includes a smart contract template for performing user information registration and order contract terms; the data storage layer is used for storing user information, automobile information and order information, and hash values and storage locations of three information raw data are stored by the blockchain layer; the physical layer includes a mobile terminal and an automobile terminal, a user sends an unlock request through the mobile terminal, the automobile terminal includes am automobile networking system and an automobile smart lock, the automobile smart lock is used for unlocking, and the automobile networking system is used for recording and uploading driving data. The system enables an owner and a renter to complete the issuance and receipt of an order through the smart contract without the need of third party participation, and reduces the transaction cost.

Description

technical field [0001] The invention relates to the technical field of cyberspace security, in particular to a keyless shared car system based on block chain technology and a construction method thereof. Background technique [0002] Efficiently managing the use of transportation assets is one of the biggest challenges facing modern cities today, and one way to address this is to use sharing economy models that reduce the number of cars by making better use of existing cars. It is worth noting that the average time utilization of a car is 5%, so encouraging users to share their cars with others could help reduce the number of cars in cities. This is possible with a keyless start car-sharing system. Users can rent a car provided by the owner somewhere in the city, obtain the right to use the car by accepting the digital key, and pay according to the time and distance traveled. Compared with traditional car rental companies, keyless start car sharing systems can provide user...

AI Technical Summary

Problems solved by technology

[0003] However, the current keyless start car sharing system has the following defects, security: the traditional intelligent connected car is in the stage of rapid development, more and more vehicles based on no physical key, the security management for the digital key still has a lot of problems. potential safety hazards; privacy: traditional keyless cars interact with manufacturers (or service providers) in real time, there is a big privacy leak problem (identity privacy, location privacy); usability: traditional keyless start car sharing system Based on centralized services, there is a single point of failure problem. Once an irresistible failure occurs in the shared system, the service will be unavailable, and the vehicles in the entire system will not be able to drive
