[0055] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. The present application provides a vehicle data sharing method and device based on blockchain, which is used in the field of data processing technology. The above is only an example and does not limit the application field of the method and device name provided by the present application.

[0056] In recent years, with the rapid development of urbanization, the traffic network has also shown an increasingly complex trend. In the process of intelligence, in addition to upgrading the driving experience, the vehicle's communication capabilities also need to have strong interactive capabilities. In the existing technology, vehicles can generally only obtain their own vehicle data and judge the driving situation based on their own vehicle data, and cannot share data with other vehicles.

[0057] After research, the inventor proposed the technical solution of this application, which first obtains vehicle data, then uploads the vehicle data to the blockchain, then analyzes the vehicle data to obtain the analysis result, responds to the request to obtain the analysis result, authenticates the user who sent the acquisition request, and if the verification is successful, sends the analysis result to the user.

It should be noted that, for ease of description, only the parts related to the relevant invention are shown in the accompanying drawings. In the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0059] See also Figure 1 , Figure 1 A flowchart of a vehicle data sharing method based on blockchain provided in an embodiment of the present application includes:

[0060] S101: Acquire vehicle data.

[0061] The vehicle data includes, but is not limited to: vehicle driving time, vehicle driving distance, vehicle direction angle, vehicle longitude data, and vehicle latitude data.

[0062] S102: Upload vehicle data to the blockchain.

[0063] Before uploading vehicle data to the blockchain, asymmetric encryption technology can be used to encrypt the vehicle data to ensure the security and privacy of the vehicle data and prevent the vehicle data from being intercepted and maliciously tampered with. The asymmetric encryption algorithm code is as follows:

[0064]

[0065] Uploading vehicle data to the blockchain and storing the vehicle data in the blockchain can ensure the security, immutability and traceability of the vehicle data.

[0066] S103: Analyze the vehicle data to obtain analysis results.

[0067] According to the vehicle travel distance Jl and the vehicle travel time Sj, the vehicle travel speed Clsd per unit time is calculated. The specific calculation method is as follows:

[0068] Clsd = AragetSd (Jl, Sj);

[0069] Among them, Clsd represents the speed of the vehicle in a unit time, and AragetSd is the function for calculating the driving speed in the smart contract. The smart contract is not described here, and will be described in detail later. The vehicle driving distance Jl and the vehicle driving time Sj are passed as parameters to this function for calculation. The speed Clsd of the vehicle in a unit time can be analyzed to obtain the evaluation result of the vehicle performance.

[0070] According to the angle between the vehicle directions, the angle Clzj generated when the vehicle turns is calculated. The specific calculation method is as follows:

[0071] Clzj = Turn (New, Old);

[0072] Among them, Clzj represents the angle generated when the vehicle turns, Turn is the function for calculating the steering angle in the smart contract, and the new direction angle New and the old direction angle are passed as parameters to this function for calculation to calculate the angle of the car when turning. The smart contract is not described here, and will be described in detail later. The calculated angle Clzj generated when the vehicle turns can be analyzed to obtain the health assessment results of the front and tires, that is, to determine whether the front and tires have performance abnormalities.

[0073] The vehicle position information Wzxx is calculated based on the vehicle's speed Clsd per unit time, the angle Clzj generated when the vehicle turns, the vehicle's longitude data Longitude, and the vehicle's latitude data Latitude. The specific calculation method is as follows:

[0074] Wzxx=GPScount(Longitude,Latitude,Clsd,Clzj);

[0075] Among them, Wzxx represents the vehicle location information, GPScount represents the positioning function in the smart contract, and the vehicle's speed per unit time Clsd, the angle Clzj generated when the vehicle turns, the vehicle's longitude data Longitude, and the vehicle's latitude data Latitude are passed as parameters to this function for calculation. The smart contract is not described here, and will be described in detail later. Analyze the vehicle's location information Wzxx to obtain the optimal route for the vehicle's corresponding road conditions.

[0076] S104: In response to the request for obtaining the analysis result, the user who sends the request for obtaining the analysis result is authenticated.

[0077] In this embodiment, a smart contract is a piece of code running on the blockchain, which is used to automatically execute pre-set rules. The core code is as follows:

[0078]

[0079] In this smart contract, a contract called CarDataSharing is defined, which includes the following important parts:

[0080] owner: The owner address of the contract. Only the owner of the contract can add or remove authorized users.

[0081] approvedUsers: A map used to store the addresses of authorized users.

[0082] carData: A nested map used to store data about each user's vehicle. The contract contains the following functions:

[0083] addApprovedUser: A function for adding authorized users. Only the owner of the contract can call it.

[0084] removeApprovedUser: Function to remove authorized users. Only the owner of the contract can call it.

[0085] shareCarData: function for sharing vehicle data, which can only be called by authorized users.

[0086] getCarData: A function for obtaining vehicle data, used to query data for a specified user and vehicle.

[0087] In response to the request for obtaining the analysis results, the user who sent the request is authenticated, that is, the user information of the user who sent the request is obtained, and the smart contract is used to determine whether the user corresponding to the user information is an authorized user. The specific authentication method is as follows:

[0088]

[0089] In the above code, two contracts are defined: IdentityRegistry and PermissionManager:

[0090] IdentityRegistry contract: used to register and manage identities. Users can call the registeredIdentity function to register their own identities, and use the isRegisteredIdentity function to check whether the identity has been registered.

[0091] PermissionManager contract: used to manage permissions. The address of the identityRegistry contract is passed into the constructor to ensure the association between permission management and identity registration. Users can call the grantPermission function to grant specific permissions to a specified identity, call the revokePermission function to revoke permissions, and call the hasPermission function to query whether a specified identity has a specific permission.

[0092] S105: If the verification is successful, the analysis result is sent to the user.

[0093] If the identity authentication of the user who requested the acquisition is passed, the analysis result is shared with the user. Collectively, a transaction for the analysis result is determined according to the smart contract, and in response to the user completing the transaction, the analysis result is sent to the user. The specific method of determining the transaction for the analysis result is shown in the following code:

[0094]

[0095]

[0096] In this way, it can be ensured that users can obtain corresponding compensation and rewards as agreed.

[0097] In the embodiment of the present application, the vehicle data is first obtained, and then the vehicle data is uploaded to the blockchain. Then, the vehicle data is analyzed to obtain the analysis result. In response to the acquisition request for the analysis result, the identity of the user who sent the acquisition request is authenticated. If the authentication is successful, the analysis result is sent to the user. In this way, by analyzing the vehicle data, obtaining the analysis result, and then sharing the analysis result with other users in response to the acquisition request, the sharing of vehicle data can be achieved.
