ALLIANCE CHAIN-BASED METHOD FOR STORING VEHICLE MAINTENANCE AND SERVICING DATA

摘要

Provided in the present invention is an alliance chain-based method for storing vehicle maintenance and servicing data. Currently, the conventional storage scheme for vehicle maintenance and servicing data is primarily storage on paper materials and dispersed local databases, such storage scheme presents many shortcomings in terms of the completeness and availability of the maintenance and servicing data. The present invention, by using blockchain technology and cloud storage technology based primarily on alliance chains, implements logically blockchain storage and physically cloud storage of maintenance and servicing data, allows real maintenance and servicing data to be tamperproof and traceable once generated and submitted to a verification node to be written into a block by a P-DPoS consensus mechanism, a user can learn in real-time the completeness of submitted data via a Merkle root verification method. Meanwhile, relevant cryptography techniques such as a public key encryption algorithm, a proxy re-encryption algorithm, and SOK protocol are employed, implemented are the disclosure and sharing of some maintenance and servicing data while ensuring the privacy and nondisclosure of personal identifies, thus providing a user with great convenience in an insurance claim process.
