Secondly, the driving data of the vehicle is managed based on a single-party device in a centralized manner at present, so that the driving data is easy to lose and tamper, and the unreliability and the risk of the data are increased.
Based on the above problems, the present application provides a method and a system for processing vehicle data, which are used to obtain environmental parameters of a vehicle and store the environmental parameters into a block chain, so as to enhance the safety of the vehicle environmental data. For easy understanding, referring to fig. 1, an embodiment of a method for processing vehicle data according to an embodiment of the present invention includes:

104. Encrypting the second data by using the first key to obtain third data;
after the vehicle data processing system obtains the second data, in order to prevent misuse and tampering of the second data by the third-party user equipment, the second data can be encrypted through the first key, so that the third data is obtained, and therefore, the third-party user equipment is guaranteed to be incapable of obtaining specific contents in the third data even if the third data is obtained on the premise that permission is not obtained.
105. Storing and registering the identification information and the third data in a block chain in an associated manner;
in order to prevent a third-party malicious website, the third data is damaged by entering the vehicle data processing system through an illegal way, and after the vehicle data processing system acquires the third data of the vehicle, the identification information of the vehicle and the third data are managed, stored and registered in the block chain.
Specifically, because the block chain is a distributed Database (or called distributed shared Ledger), because of structural characteristics of distributed records and distributed storage of the block chain itself, the block chain has characteristics of decentralization (Decentralized), trust removal (trust), collective maintenance (collectivelymaitain), Reliable Database (Reliable Database), Open Source (Open Source), and privacy protection (privacy), so that after the third data of the vehicle is uploaded to the block chain, the identification information and the third data cannot be tampered.
106. Receiving a data request of third-party user equipment, wherein the data request comprises identification information of a vehicle;
after the processing system of the vehicle data registers the third data in the blockchain, if the third-party user equipment needs to acquire the third data, a data request may be generated to the processing system of the vehicle data, where the data request includes: the identification information of the vehicle, so that the processing system of the vehicle data can quickly find the third data of the vehicle associated with the identification information of the vehicle according to the identification information of the vehicle.
After the third-party user device sends the data request, the vehicle data management system may receive the data request.
107. And sending third data corresponding to the identification information in the data request to the third-party user equipment.

Referring to fig. 2, a method for processing vehicle data according to an embodiment of the present invention is described in detail below based on the embodiment illustrated in fig. 1, where another embodiment of the method for processing vehicle data according to an embodiment of the present invention includes:
201. receiving a registration request of the terminal equipment, and generating a first key according to the identification information of the terminal equipment;
in order to ensure the authenticity of data stored in a vehicle data processing system and the management of vehicle environment parameters in the later period, the vehicle data processing system needs to verify a terminal device (a vehicle-mounted device), namely, to acquire the authentication information of the terminal device, and establish data interaction with the terminal device after the authentication of the terminal device is passed.
Specifically, the form of the authentication information may be various, for example, the terminal device sends a registration request to the processing system of the vehicle data, where the registration request may include identification information (such as a device ID, etc.) of the terminal device to obtain a static password for login; or after the terminal device sends a registration request to the vehicle data processing system and completes registration, the terminal device acquires a magnetic card or an intelligent card for identifying identity; or after the terminal device sends a registration request to the vehicle data processing system and completes registration, the terminal device authenticates the identity of the terminal device in a dynamic password mode before data interaction occurs with the vehicle data processing system, and the like. The authentication information between the terminal device and the vehicle data processing system includes, but is not limited to, the above several ways, and the form of the authentication information is not particularly limited herein.
Further, after receiving the registration request of the terminal device, the processing system of the vehicle data may generate the first key according to the identification information of the terminal device in the registration request, so as to encrypt the relevant data of the vehicle at a later stage. Specifically, the first key in this embodiment may be a private key in an asymmetric encryption algorithm, or may be a fixed password in a symmetric encryption algorithm, where the form of the first key is not specifically limited.
202. Acquiring identification information and environmental parameters of a vehicle through terminal equipment;
after the terminal device completes registration in the vehicle data processing system, the vehicle data processing system can acquire and process the environmental parameters of the vehicle through the terminal device (vehicle-mounted device) so as to provide a real and powerful data base for vehicle maintenance in the later period. Specifically, the environmental parameters of the vehicle include, but are not limited to, the temperature, humidity, and dust concentration of the vehicle environment, and it is understood that the ambient temperature of the vehicle, the ambient humidity of the vehicle, and the ambient dust concentration of the vehicle can be obtained by a temperature sensor, a humidity sensor, and a dust concentration sensor mounted on the vehicle, respectively.
Further, in order to provide index and identification for the environmental parameters of the vehicle, the processing system of the vehicle data can acquire the identification information of the vehicle while acquiring the environmental parameters of the vehicle, so as to be used for the later rapid identification of different environmental parameters of the vehicle. The identification information of the vehicle includes, but is not limited to, the engine model of the vehicle, the VIN code of the vehicle, the model and the style of the vehicle.
203. Determining an adverse environmental factor of an environmental parameter;
after obtaining environmental parameters of the vehicle, such as the environmental temperature, the environmental humidity, the atmospheric pressure and the environmental dust concentration of the vehicle, the vehicle data processing system calculates the altitude according to the atmospheric pressure, and then accesses the weather database through the API interface to obtain the adverse environmental factors (F1, F2 and … Fn) of each environmental parameter from the weather database.
204. Determining the influence coefficient of the adverse environment factor on each part of the vehicle;
after the vehicle data processing system determines the adverse environmental factors, the influence coefficients (C1, C2, … Cm) of the adverse environmental factors on the various components (component 1, component 2 …, component m) of the vehicle are determined from the pre-stored experimental statistical data table. The experimental statistical data table is the influence coefficient of different environmental factors on the vehicle according to a large number of experimental statistics.
205. According to a preset first algorithm, calculating the wear rate of each part of the vehicle by using the adverse environment factor and the influence coefficient;
vehicle data processing systemAfter determining the adverse environmental factors of the environmental parameters and the influence coefficients of the adverse environmental factors on various parts of the vehicle, the adverse environmental factors can be calculated according to a formula
Calculating the wear rate of the part m caused by the influence of each adverse environmental factor, and when the historical record number is r, the overall wear rate of the part m is
By analogy, the historical wear rates of various environmental factors on different components can be calculated.
206. Calculating the depreciation rate of the vehicle by using the wear rate of each part according to a preset second algorithm;
after the processing system of the vehicle data determines the wear rate of each part according to the environmental factor and the influence coefficient, the processing system of the vehicle data determines the wear rate of each part according to the weighting factors (r1, r2 … rm) of the wear rate of each part to the vehicle according to the formula
And calculating the wear rate of each part to the depreciation rate of the whole vehicle.
207. Packaging the wear rate of each part of the vehicle, the depreciation rate of the vehicle and the collected environmental parameters to generate first data;
the vehicle data processing system adopts a preset algorithm to obtain the wear rate of each part of the vehicle and the depreciation rate of the vehicle according to the collected environmental parameters, and encapsulates the wear rate of each part of the vehicle, the depreciation rate of the vehicle and the collected environmental parameters to generate first data for centralized and unified management and storage of the data so as to provide a data base for later maintenance of the vehicle.
208. Processing the identification information and the first data according to a preset format to obtain second data;
for the ordered management and storage of the vehicle data, after the vehicle data processing system obtains the first data, the identification information of the vehicle and the first data can be processed according to a preset format to obtain second data, so that the identification information of the vehicle and the first data in the second data are correlated to each other for the fast search of the vehicle data in the later period.
Specifically, the preset format is a format for realizing the correlation between the identification information of the vehicle and the first data of the vehicle, and is not limited specifically here.
209. Calculating the second data by adopting a preset algorithm to obtain fourth data;
further, in order to prevent the vehicle data processing system from tampering with a malicious website during registration of the vehicle data into the blockchain after calculating the vehicle depreciation rate according to the environmental parameters, the vehicle data processing system obtains fourth data (a hash value or an MD5 value of the second data) from second data of the vehicle by using a one-way irreversible algorithm (such as a hash algorithm or an MD5 algorithm), and stores the fourth data into the blockchain, so that a third party can verify the second data of the vehicle by using the one-way irreversible algorithm after downloading the second data of the vehicle.
According to the nature of the one-way irreversible algorithm, the hash value or MD5 value is a unique and extremely compact representation of a piece of data, and if a piece of plaintext is hashed and even if only one letter of the paragraph is altered, the subsequent hash or MD5 value will produce a different value. So after obtaining the second data, the third party can verify whether the second corresponding hash or MD5 value is changed according to the one-way irreversible algorithm, and if not, prove that the second data is complete, otherwise, the second data of the vehicle has been tampered.
210. Encrypting the second data by using the first key to obtain third data;
after the vehicle data processing system obtains the second data, in order to prevent misuse and tampering of the second data by the third-party user equipment, the second data can be encrypted through the first key, so that the third data is obtained, and therefore, the third-party user equipment is guaranteed to be incapable of obtaining specific contents in the third data even if the third data is obtained on the premise that permission is not obtained.
211. Storing and registering the identification information, the third data and the fourth data in a block chain in an associated manner;
in order to prevent a third-party malicious website, the third data and the fourth data are damaged by entering the vehicle data processing system through an illegal way, and after the third data and the fourth data of the vehicle are acquired, the vehicle data processing system stores and registers the identification information of the vehicle, the third data and the fourth data in a block chain in an associated mode.
Specifically, because the block chain is a distributed Database (or called distributed shared Ledger), because of structural characteristics of distributed records and distributed storage of the block chain itself, the block chain has characteristics of decentralization (Decentralized), trust removal (trust), collective maintenance (collectivelymaitain), Reliable Database (Reliable Database), Open Source (Open Source), and privacy protection (privacy), so that after the third data of the vehicle is uploaded to the block chain, the identification information, the third data, and the fourth data cannot be tampered.
212. Receiving a data request of third-party user equipment, wherein the data request comprises identification information of the vehicle and equipment identification of the third-party user equipment;
after the processing system of the vehicle data registers the third data in the blockchain, if the third-party user equipment needs to acquire the third data, a data request may be generated to the processing system of the vehicle data, where the data request includes: the identification information of the vehicle, so that the processing system of the vehicle data can quickly find the third data of the vehicle associated with the identification information of the vehicle according to the identification information of the vehicle. Meanwhile, in order to verify the identity of the third-party user equipment, the data request may further include an equipment identifier of the third-party user equipment, so that the vehicle data processing system verifies the identity of the third-party user equipment according to the equipment identifier of the third-party user equipment.
213. Authenticating the third-party user equipment according to the equipment identification to determine whether to send a second secret key to the third-party user equipment, wherein the second secret key corresponds to the first secret key;
it is understood that, after receiving the data request of the third-party user device, the vehicle data processing system may verify the identity of the third-party user device according to the device identifier of the third-party user device in the data request to determine whether to send the second key to the third-party user device.
Such as: after receiving the device identifier of the third-party user equipment, the vehicle data processing system can query the device identifier at an official website of the device identifier, and further send a second key to the third-party user equipment if the query result shows that the identity of the third-party user equipment is qualified, wherein the second key corresponds to the first key for encrypting the second data and is used for decrypting the third data.
Specifically, if the encryption algorithm is an asymmetric encryption algorithm, the second key is a public key corresponding to the first key, and if the encryption algorithm is a symmetric encryption algorithm, the second key is the same as the first key.
214. And sending third data corresponding to the identification information in the data request to the third-party user equipment.
And after the processing system of the vehicle data finds the third data corresponding to the vehicle according to the identification information of the vehicle, the third data is further sent to the third user equipment for reference or further processing by the third user equipment.
It can be understood that, after the authentication is passed, the third-party user equipment may receive the second secret key sent by the vehicle data processing system, and after receiving the third data, decrypt the third data through the corresponding second secret key to obtain the identification information of the vehicle and the first data, where the specific first data includes the wear rate of each component of the vehicle, the depreciation rate of the vehicle, and the collected environmental parameters for the third-party user to refer to.
The method comprises the steps of firstly obtaining identification information and environmental parameters of a vehicle, processing the environmental parameters by adopting a preset algorithm to generate first data, processing the identification information and the first data according to a preset format to obtain second data, encrypting the second data by using a first secret key, and storing the identification information and the second data of the vehicle in a block chain in a correlation manner, so that real environmental parameters are provided for basic maintenance of the vehicle in the later period, and the vehicle environmental parameters in the block chain cannot be tampered by storing the environmental parameters in the block chain, so that when a data request of a third party is received, the real vehicle environmental parameters can be sent to the third party according to the data request.
Secondly, after the second data is obtained, in order to verify whether the second data is tampered or not in the later period, the second data is calculated through a preset algorithm (Hash or MD5) to obtain fourth data, a third party user can conveniently verify whether the second data is tampered or not, and the safety of the vehicle environment parameters is further enhanced.
In the above, a method for processing vehicle data in an embodiment of the present invention is described, and a system for processing vehicle data in an embodiment of the present invention is described below, referring to fig. 3, the system for processing vehicle data in an embodiment of the present invention includes:
