Automobile data tamper-proofing system and data access method

Abstract

The invention provides an automobile data tamper-proofing system and a data access method, and the method comprises the steps: obtaining automobile data in real time, encrypting the automobile data toform first encrypted data and second encrypted data, transmitting the first encrypted data to a data center for storage, and transmitting the second encrypted data to a blockchain cloud for storage;wherein the data encryption modes of the first encrypted data and the second encrypted data are different; and when the data center is inconsistent with the data stored in the block chain cloud, performing data replacement based on the data stored in the block chain cloud, and broadcasting to notify other users. According to the method, the mileage is effectively verified based on safe data storage of the blockchain cloud, tamper-proofing of the automobile data is effectively guaranteed in real time, fair and credit guarantee can be further provided for a second-hand vehicle transaction process technically, and real condition data of an automobile is prevented from being tampered artificially.

Description

technical field [0001] The invention relates to the technical field of automobile safety, in particular to an automobile data tamper-proof system and a data access method. Background technique [0002] As the most important link in the automobile circulation value chain, used cars have huge potential and unprecedented prospects. In the 15 years from 2000 to 2014, the transaction volume of the second-hand car market rose to 6.053 million vehicles, and the transaction amount has reached 367.565 billion yuan. With the rapid growth of the circulation scale of second-hand cars, the value of second-hand cars depends on comprehensive conditions such as vehicle conditions and mileage. There are a large number of modified mileages, but the current industry warnings lack effective supervision, resulting in a lack of fairness and credit in the process of second-hand car transactions; frequent occurrences The act of tampering with the odometer, in the absence of effective supervision i...

With the rapid growth of the circulation scale of second-hand cars, the value of second-hand cars depends on comprehensive conditions such as vehicle conditions and mileage. There are a large number of modified mileages, but the current industry warnings lack effective supervision, resulting in a lack of fairness and credit in the process of second-hand car transactions; frequent occurrences The behavior of tampering with the odometer, under the current lack of effective supervision of the industry, it is urgent to provide fairness and credit protection for the process of second-hand car transactions technically, and prevent artificial tampering with the real condition data of the car, such as the odometer, etc.
