[0058] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0059] Existing vehicle information is usually provided by the seller of the vehicle, and usually only includes information such as vehicle appearance, insurance information, maintenance information, and vehicle mileage. The buyer cannot verify the integrity and authenticity of the vehicle information. For example, if the seller chooses an informal vehicle repair shop to repair the vehicle after a serious accident, the repair record cannot be verified, resulting in low integrity and authenticity of the vehicle information obtained by the buyer. The embodiment of the present invention provides a vehicle information processing method, such as Figure 1 As shown, the method includes:

[0060] 101. In response to an information operation request of a target vehicle, obtain at least one of the key information, service transaction information, and vehicle transaction status information of the user who issued the request, and determine the target blockchain node from the blockchain nodes based on the key information.

[0061] In an embodiment of the present invention, a user can log in to the vehicle information management system through any terminal device and initiate an information operation request to manipulate vehicle information based on the system. Upon receiving the request, the system server obtains one or more of the current user's key information, service transaction information, and the target vehicle's transaction status information. Based on the key information, the server determines the user category of the currently logged-in user. For example, the server can determine whether the currently logged-in user is a vehicle information query user, a vehicle management office, or an insurance company. This determines the blockchain nodes that the user can operate based on the user category. The vehicle information management system is connected to a vehicle information consortium chain. The consortium chain utilizes an authorization mechanism, granting keys corresponding to different information operation permissions to different user categories. This consortium chain connects the vehicle information management system to entities with vehicle information management qualifications, such as vehicle manufacturers, vehicle management offices, insurance companies, used car trading companies, and vehicle repair shops; the querying side, such as individual users and used car trading companies; and the regulatory side, such as vehicle information regulatory authorities, to form a comprehensive vehicle information management ecosystem. Among them, for the accounting link of the accounting blockchain node, based on the blockchain application component WeBase (WeBank Blockchain Application Software Extension), it integrates FISCO BCOS JavaSDK, provides a RESTful-style interface, connects the accounting system to the WeBase application component, authorizes the private key to the corresponding accounting service unit through WeBase, and connects the accounting service unit to the alliance chain.

[0062] It should be noted that blockchain nodes include query blockchain nodes and accounting blockchain nodes. The query blockchain nodes store vehicle information classification tags corresponding to different information categories. These vehicle information classification tags are derived from processing the raw vehicle information in the accounting blockchain nodes. That is, the vehicle information stored in the query blockchain nodes is derived from the integration of accounting information from different authorized entities. For example, the raw vehicle information in each accounting blockchain node is aggregated and divided according to time attributes and business attributes to obtain multiple different categories of vehicle information, including vehicle factory information, vehicle maintenance information, vehicle violation annual inspection information, and vehicle circulation information. Different classification tags are assigned to different information categories. By integrating the accounting information from relevant accounting nodes in the consortium chain and storing the resulting vehicle information classification tags in the query blockchain node, an effective connection between vehicle information query and vehicle information accounting is achieved. Furthermore, because the consortium chain represents a compromise between public and private blockchains for accounting, it effectively ensures the immutability of vehicle information, thereby effectively guaranteeing the security, integrity, and accuracy of queried vehicle information.

[0063] 102. If the target blockchain node is a query blockchain node, the vehicle transaction status information, the service transaction information, and the information operation request are forwarded to the target blockchain node, so that the target blockchain node executes a query on the target vehicle information based on the vehicle transaction status information, the service transaction information, and the information operation request.

[0064] In an embodiment of the present invention, a public access platform for vehicle information query is built based on web3.0 technology. Users can purchase vehicle information query services for designated vehicles by logging into the platform. Vehicle information on the platform is packaged as services available for purchase by users according to different classification tags. Different service prices correspond to different transaction levels, and different transaction levels correspond to vehicle information under different classification tags. If the target blockchain node is a query blockchain node, indicating that the information operation request issued by the current user is for a query of vehicle information, that is, the current user has purchased the vehicle information query service for the target vehicle, the information operation request is forwarded to the target blockchain node for processing. At the same time, the scope of the vehicle information query is determined by the target vehicle's transaction status information and service transaction information. Therefore, the target vehicle's transaction status information and service transaction information also need to be forwarded to the target blockchain node so that the target blockchain node can determine the vehicle information tags that can be queried based on the target vehicle's transaction status information and service transaction information, and query the target vehicle's information based on the vehicle information tags.

[0065] It should be noted that since the public access platform for vehicle information query is built based on web3.0 technology, users can log in to the system platform through associated clients, such as wallet account clients, WeChat clients, etc., without having to use user private information such as email, mobile phone number, ID number, etc. to register and log in to the account, which better meets the user's privacy and confidentiality needs.

[0066] 103. Obtain the target vehicle information query result of the target blockchain node, and send the target vehicle information query result to the terminal.

[0067] In this embodiment of the present invention, after the target blockchain node completes its query for the target vehicle's information, it also needs to obtain the target vehicle information query results and send them to the terminal device that initiated the information operation request, so that the terminal device can display the target vehicle information query results to the user, allowing users who purchase the target vehicle information service to view the corresponding vehicle information. Because the vehicle information comes from the consortium chain, the recorded vehicle information is authentic vehicle information uploaded by a third-party credit entity and cannot be tampered with or deleted, fully guaranteeing the integrity, authenticity, and objectivity of the vehicle information.

[0068] In one embodiment of the present invention, for further explanation and limitation, as Figure 2 As shown, the step wherein the target blockchain node performs a query on the target vehicle information according to the vehicle transaction status information, the service transaction information, and the information operation request includes:

[0069] 201. Determine a first operation information tag from the vehicle information classification tags based on the vehicle transaction status information, and determine a second operation information tag from the vehicle information classification tags based on the service transaction information.

[0070] 202. Determine an intersection of the first operation information tag, the second operation information tag, and the initial operation information tag carried in the information operation request as a target operation information tag.

[0071] 203. Query and process the target vehicle information according to the target operation information tag.

[0072] In the embodiments of the present invention, since vehicle information records events throughout the vehicle's life cycle, from factory to scrapping, vehicle information is the owner's private information. To ensure the security of vehicle information, vehicle information query services cannot be provided under all circumstances. Instead, services need to be provided under specific scenario requirements. For example, when a vehicle is in a used car transaction state, a vehicle information query service can be provided to meet the vehicle buyer's assessment of the vehicle's residual value. However, if the target vehicle has not entered the used car transaction market, a vehicle information query service for the target vehicle cannot be provided, or only a query service for some publicly available vehicle information can be provided. Therefore, it is necessary to determine the label of the vehicle information that can be operated based on the vehicle transaction status information, namely the first operation information label. The vehicle transaction status can be a transaction status or a non-transaction status. Other states can also be set according to the actual application scenario, such as a transaction completion status, a transaction processing status, etc., which are not specifically limited in the embodiments of the present invention.

[0073] In this embodiment of the present invention, vehicle information query services under different classification tags correspond to different transaction permissions, meaning that users purchase different vehicle information query permissions by paying different prices. For example, 10 yuan can purchase vehicle information query services under the target vehicle's accident and annual inspection information tag, while 20 yuan can purchase vehicle information query services under the target vehicle's accident and annual inspection information tag and repair information tag. Different prices can also correspond to vehicle information under different time range tags, though this embodiment is not specifically limited. Therefore, it is necessary to determine the information classification tags that the current user can view, namely the second operation information tag, based on the service transaction information. To meet user needs, after determining the first and second operation information tags, it is necessary to parse the initial operation information tag carried in the information operation request and take the common intersection tag of the three tags as the target operation information tag for the final query. The initial operation information tag can be a vehicle information tag option entered by the user through the terminal device, or it can be generated based on the user's vehicle information grouping options, though this embodiment is not specifically limited. By jointly determining the target operation information tag based on vehicle transaction status information, service transaction information, and information operation requests, vehicle information transaction services are standardized while meeting user needs, thereby significantly ensuring the security of vehicle information.

[0074] In one embodiment of the present invention, for further explanation and limitation, the step of determining the first operation information tag from the vehicle information classification tag based on the vehicle transaction status information includes:

[0075] If the vehicle transaction status information is a transaction status, determining at least one category of vehicle information among maintenance information, insurance information, violation information, transaction information, and accident information in the vehicle classification information as a first operation information tag;

[0076] If the vehicle transaction status information is a non-transaction status, the content of the first operation information tag is configured to be empty.

[0077] In an embodiment of the present invention, in order to ensure the privacy of the target vehicle's vehicle information, it is determined whether to provide query services to the information query user and which categories of vehicle information query services to provide based on the vehicle transaction status information. For example, if the target vehicle is a vehicle that has been in a serious accident, when the vehicle transaction status information is in a transaction status, in order to enable the user to understand the condition of the target vehicle, maintenance information and accident information are used as information for query, and the maintenance information label and the accident information label are used as the first operation information label. For another example, if the target vehicle is a vehicle that has been traded as a used car, when the vehicle transaction status information is in a transaction status, in order to enable the user to understand the circulation status of the target vehicle, transaction information and insurance information are used as information for query, and the transaction information label and the insurance information label are used as the first operation information label. The type of vehicle information based on which the first operation information label is determined can be customized according to the actual application scenario, and the embodiment of the present invention does not make any specific restrictions. When the vehicle transaction status information is in a non-transaction state, that is, the target vehicle has not entered the used car market for sale, there is no need to disclose the information of the target vehicle to the public. By leaving the content of the first operation information tag blank, the information of the target vehicle can be prevented from being queried to protect the privacy of the owner of the target vehicle.

[0078] In one embodiment of the present invention, for further explanation and limitation, the step of determining the second operation information tag from the vehicle information classification tag based on the service transaction information includes:

[0079] Matching a target service group from a service group mapping relationship set according to the service transaction information;

[0080] The vehicle information tag that matches the information category in the target service group in the vehicle information classification tags is determined as the second operation information tag.

[0081] In an embodiment of the present invention, a service group mapping relationship set includes mapping relationships between different vehicle information groups and different preset service levels. A vehicle information group includes a vehicle information classification tag for at least one vehicle information category, and the preset service levels may include multiple preset service levels. For example, a first preset service level corresponds to a first vehicle information group, which includes two vehicle information classification tags, and a second preset service level corresponds to a second vehicle information group, which includes three vehicle information classification tags. The first vehicle information group may also include specific vehicle information classification tags, for example, a repair information tag and an accident information tag, and an insurance information tag, a violation information tag, and a transaction information tag. The embodiment of the present invention does not specifically limit the specific division of preset service levels and vehicle information groups. Furthermore, different vehicle information groups may also include classification tags corresponding to vehicle residual value assessment reports and vehicle affordability assessment reports based on multiple vehicle information categories to meet the vehicle information query needs of different users. By classifying and grouping vehicle information to form a vehicle information service product, flexible and diversified vehicle information query services are achieved, thereby meeting the needs of different vehicle information query users and improving the user experience.

[0082] In one embodiment of the present invention, for further explanation and limitation, the step of determining the target blockchain node from the blockchain nodes based on the key information includes:

[0083] Parsing the key information to determine the user category of the user issuing the request;

[0084] If the user category is the first user category, obtaining the user's historical accounting category, and determining the blockchain node that matches the historical accounting category among the accounting blockchain nodes as the target blockchain node;

[0085] If the user category is the second user category, the login attribute information of the user is obtained, and a query blockchain node is matched from the query blockchain nodes as the target blockchain node according to the login attribute information.

[0086] In an embodiment of the present invention, user categories include a first user category and a second user category. The first user category is a user with accounting authority, and its key type is a private key. The second user category is a user with vehicle information query authority, and its key type is a public key. With respect to the first user category, since there are multiple accounting blockchain nodes, and each user is usually only authorized to perform accounting on one category of accounting blockchain nodes, for example, a user affiliated with a vehicle management office can only operate on the accounting blockchain node corresponding to the vehicle management office. Therefore, it is necessary to match the user's historical accounting category with the category of the accounting blockchain node to determine the accounting blockchain node that the user can operate. In addition, a mapping relationship between key information and accounting blockchain node operation authority can be pre-constructed, and then the accounting blockchain node to which the user's operation authority points can be determined based on the key information, and the pointed accounting blockchain node is used as the target blockchain node.

[0087] In an embodiment of the present invention, the login attribute information may be the geographic region information of the user's network IP address. For the second user category, since the query blockchain nodes supporting user queries may be distributed across multiple geographic regions, i.e., vehicle information within different geographic regions is stored within query blockchain nodes within corresponding regions, to improve query efficiency, the login attribute information may be obtained, and the user's login geographic region may be determined based on the login attribute information. The query blockchain node corresponding to the same geographic region may then be identified as the target blockchain node. Alternatively, the query blockchain node with the lowest query volume may be identified as the target blockchain node based on the query volume of the query blockchain node, but this is not specifically limited in the embodiment of the present invention.

[0088] In one embodiment of the present invention, for further illustration and limitation, the method further includes:

[0089] If the target blockchain node is an accounting blockchain node, the information operation content and the key information carried in the information operation request are forwarded to the target blockchain node, so that the target blockchain node performs authority verification based on the key information, and when the authority verification result is passed, the information of the target vehicle is accounted for according to the information operation content.

[0090] In this embodiment of the present invention, when the target blockchain node is a bookkeeping blockchain node, indicating that the information operation is a bookkeeping operation on vehicle information, it is necessary to obtain the information operation content carried in the information operation request and perform bookkeeping based on the information operation content. For example, if the target blockchain node corresponds to the bookkeeping node of an authorized repair shop, the information operation content may include recording vehicle maintenance information or vehicle repair information, etc., although this embodiment of the present invention does not impose specific limitations. Because the key of the bookkeeping blockchain node is a private key, key information must be verified to verify the operating authority of the current operating user, thereby ensuring the authenticity and accuracy of the bookkeeping information.

[0091] In one embodiment of the present invention, for further illustration and limitation, the method further includes:

[0092] Forwarding the service transaction information and / or the information operation request to the regulatory blockchain node, so that the vehicle information regulatory side verifies the vehicle information transaction and / or vehicle information operation;

[0093] The result of the verification is obtained. If the result of the verification is that the verification has failed, a warning message is generated to indicate that the vehicle information transaction and / or vehicle information operation is in violation of the regulations, and the warning message is sent to the monitoring terminal.

[0094] In an embodiment of the present invention, the blockchain node also includes a supervisory blockchain node, which corresponds to the supervisory side of the information query service. When the target blockchain node is a query blockchain node, service transaction information and / or information operation requests are sent to the supervisory blockchain node to verify the service transaction information and information operation requests based on first preset verification conditions. The first preset verification conditions may include a service transaction amount threshold, a vehicle information classification tag corresponding to the service transaction, and the like, but are not specifically limited in this embodiment. If the service transaction information or information operation request does not meet the corresponding preset verification conditions, it indicates that the current vehicle information query service transaction has violated the operation rules. When the target blockchain node is a bookkeeping blockchain node, the information operation request is sent to the supervisory blockchain node to verify the information operation request based on second preset verification conditions. The second preset verification conditions may include deletion, addition, modification, and other operations, and can also be customized based on actual application needs, but are not specifically limited in this embodiment. For example, if the vehicle information on the vehicle management office blockchain node is only allowed to be added, if the information operation content carried in the information operation request includes a modification operation, the verification result is considered to have failed. When the warning information is generated, it will be sent to the terminal device of the supervisor, that is, the monitoring terminal, so that the supervisor can intervene or deal with the current user's operation behavior accordingly, thereby ensuring the security of vehicle information and the standardization of vehicle information query services.
