For existing vehicle information is usually provided by a vehicle seller, the information such as vehicle appearance, insurance information, maintenance information, vehicle mileage and the like can be only contained, and a buyer cannot verify the integrity and authenticity of the vehicle information, for example, a seller selects a non-regular vehicle maintenance shop for maintenance after a serious accident of the vehicle, then the maintenance record cannot verify, so that the integrity and authenticity of the vehicle information acquired by a buyer are low. The embodiment of the invention provides a vehicle information processing method, as shown in fig. 1, comprising the following steps:
101. and responding to the information operation request of the target vehicle, acquiring at least one of key information, service transaction information and vehicle transaction state information of a user, and determining a target blockchain node from the blockchain nodes according to the key information.
In the embodiment of the invention, a user can log in the vehicle information management system through any terminal equipment and initiate an information operation request for operating the vehicle information based on the system. When the system server receives the request, one or more of key information of the current user, service transaction information, and vehicle transaction status information of the target vehicle are acquired, and a user category of the current login user is determined based on the key information, for example, the current login user is determined to be a vehicle information inquiry user, a vehicle management center, an insurance company, and the like based on the key information, so that a blockchain node which can be operated by the user is determined according to the user category. Wherein the vehicle information management system accesses a vehicle information alliance chain. The alliance chain grants keys corresponding to different information operation authorities to different types of users through an authorization mechanism, and enables billing sides of vehicle information, such as units with vehicle information management qualification, such as a vehicle factory, a vehicle management center, an insurance company, a second-hand vehicle transaction company, a vehicle maintenance shop and the like, inquiry sides, such as individual users, second-hand vehicle transaction enterprises and the like, and supervision sides, such as vehicle information supervision departments, to access a vehicle information management system to form a full-flow ecological system of vehicle information management. The accounting system is accessed to the WeBase application component based on the blockchain application component WeBase (WeBank Blockchain Application Software Extension), the integration FISCO BCOS JavaSDK and the RESTful style interface for the accounting link of the accounting blockchain node, and the accounting service units are accessed to the alliance chain through the WeBase authorization private key to the corresponding accounting service units.
It should be noted that, the blockchain node includes a query blockchain node and an accounting blockchain node, the query blockchain node stores vehicle information classification labels corresponding to different information categories, the vehicle information classification labels are obtained based on original vehicle information processing in the accounting blockchain node, that is, the vehicle information stored in the query blockchain node is vehicle information obtained based on accounting information integration of different authorization units. For example, the original vehicle information in each billing blockchain node is summarized and divided according to time attribute and service attribute to obtain a plurality of different types of vehicle information including vehicle factory information, vehicle maintenance information, vehicle violation annual inspection information, vehicle circulation information and the like, and different classification labels are configured for the different types of information. The method has the advantages that the billing information in the related billing nodes in the alliance chain is integrated, and the integrated vehicle information classification labels are stored in the query blockchain nodes, so that the effective connection between vehicle information query and vehicle information billing is realized, and meanwhile, the situation that the vehicle information cannot be tampered can be effectively ensured because the alliance chain is a billing mode based on a compromise between a public chain and a private chain, and therefore the safety, the integrity and the accuracy of vehicle information query can be effectively ensured.
102. And if the target blockchain node is a query blockchain node, forwarding the vehicle transaction state information, the service transaction information and the information operation request to the target blockchain node so that the target blockchain node executes the query on the target vehicle information according to the vehicle transaction state information, the service transaction information and the information operation request.
In the embodiment of the invention, a public access platform for inquiring vehicle information is built based on the web3.0 technology, and a user can purchase the vehicle information inquiring service of the appointed vehicle by logging in the platform. The vehicle information in the platform is packaged into services which can be purchased by users according to different classification labels, different service prices correspond to different transaction levels, and different transaction levels correspond to the vehicle information under different classification labels. If the target blockchain node is a query blockchain node, the information operation request sent by the current user is used for requesting to query the vehicle information, namely, the current user purchases the vehicle information query service of the target vehicle, and the information operation request is forwarded to the target blockchain link point for processing. Meanwhile, the vehicle information query range is determined by the target vehicle transaction state information and the service transaction information, so that the target vehicle transaction state information and the service transaction information are required to be forwarded to the target blockchain node together, and the target blockchain node can determine a vehicle information tag capable of being queried according to the target vehicle transaction state information and the service transaction information so as to query the information of the target vehicle according to the vehicle information tag.
It should be noted that, because the public access platform for inquiring vehicle information is set up based on the web3.0 technology, the user can log in the system platform through the associated client, for example, the wallet account client, the WeChat client and the like, and the user private information such as a mailbox, a mobile phone number, a certificate number and the like is not required to be used for registering the login account, so that the privacy and confidentiality requirements of the user are better met.
103. And acquiring a target vehicle information inquiry result of the target blockchain node, and sending the target vehicle information inquiry result to a terminal.
In the embodiment of the invention, after the target block link points complete the inquiry of the information of the target vehicle, the target vehicle information inquiry result is required to be acquired and is sent to the terminal equipment initiating the information operation request, so that the terminal equipment displays the target vehicle information inquiry result to the user, and the user purchasing the target vehicle information service can view the corresponding vehicle information. The vehicle information comes from the alliance chain, wherein the recorded vehicle information is the vehicle real information uploaded by the third party credit bureau and cannot be tampered or deleted, so that the integrity, the authenticity and the objectivity of the vehicle information can be fully ensured.
For further explanation and limitation, as shown in fig. 2, the step of the target block link point executing the query for the target vehicle information according to the vehicle transaction status information, the service transaction information, and the information operation request includes:
201. and determining a first operation information label from the vehicle information classification labels according to the vehicle transaction state information, and determining a second operation information label from the vehicle information classification labels according to the service transaction information.
202. And determining the intersection of the first operation information label, the second operation information label and the initial operation information label carried by the information operation request as a target operation information label.
203. And inquiring the information of the target vehicle according to the target operation information tag.
In the embodiment of the invention, since the vehicle information records the event of the whole life cycle from delivery to scrapping of the vehicle, the vehicle information belongs to the privacy information of the vehicle owner, and in order to ensure the safety of the vehicle information, the vehicle information query service cannot be provided under any condition, but the service needs to be provided under specific scene requirements, for example, when the vehicle is in a second-hand vehicle transaction state, the vehicle information query service can be provided in order to meet the evaluation of the vehicle residual value by the vehicle purchaser. However, if the target vehicle does not enter the second-hand vehicle trade market, the vehicle information inquiry service of the target vehicle cannot be provided, or the inquiry service of part of the vehicle information which can be disclosed can be provided as far as possible. Therefore, it is necessary to determine a tag of the operable vehicle information, i.e., a first operation information tag, based on the vehicle transaction state information. The vehicle transaction state may be a transaction state or a non-transaction state, or other states may be set according to an actual application scenario, such as a transaction completion state, a transaction handling state, etc., which are not limited in particular.
In the embodiment of the invention, the vehicle information inquiry services under different classification labels correspond to different transaction authorities, namely, the user purchases different vehicle information inquiry authorities by paying different prices. For example, the 10-element can purchase the query service of the vehicle information under the accident annual inspection information label of the target vehicle, the 20-element can purchase the query service of the vehicle information under the accident annual inspection information label and the maintenance information label of the target vehicle, and the vehicle information under the labels in different time ranges can be corresponding to different prices, and the embodiment of the invention is not particularly limited. Therefore, it is necessary to determine an information category tag, i.e., a second operation information tag, that can be viewed by the current user according to the service transaction information. In order to meet the requirements of users, after the first operation information label and the second operation information label are determined, the initial operation information label carried in the information operation request is needed to be analyzed, and the public intersection label of the three labels is taken as the target operation information label of the final query. The initial operation information tag may be a vehicle information tag option input by the user through the terminal device, or may be generated according to a vehicle information grouping option of the user, which is not particularly limited in the embodiment of the present invention. The target operation information label is determined together based on the vehicle transaction state information, the service transaction information and the information operation request, and the vehicle information transaction service is standardized on the basis of meeting the user requirements, so that the safety of the vehicle information is greatly ensured.
In an embodiment of the present invention, for further explanation and limitation, the determining the first operation information tag from the vehicle information classification tags according to the vehicle transaction status information includes:
if the vehicle transaction state information is a transaction state, determining at least one type of vehicle information of maintenance type information, insurance type information, violation type information, transaction type information and accident type information in the vehicle classification information as a first operation information label;
and if the vehicle transaction state information is in a non-transaction state, configuring the content of the first operation information label to be empty.
In the embodiment of the invention, in order to ensure the privacy of the vehicle information of the target vehicle, whether to provide query service for the information query user and provide query service for the category of vehicle information are determined according to the vehicle transaction state information. For example, when the vehicle transaction state information is a transaction state, the maintenance information and the accident information are used as information for inquiry, and the maintenance information tag and the accident information tag are used as the first operation information tag, so that the user can know the vehicle condition of the target vehicle. For example, when the vehicle transaction state information is a transaction state, the transaction type information and the insurance type information are used as information for inquiry, and the transaction type information tag and the insurance type information tag are used as the first operation information tag, so that the user can know the circulation state of the target vehicle. The first operation information tag is determined based on what kind of vehicle information can be customized according to the actual application scenario, and the embodiment of the invention is not particularly limited. When the vehicle transaction state information is in a non-transaction state, namely the target vehicle does not enter the second-hand vehicle market for sale, the information of the target vehicle does not have the necessity of being externally disclosed, and the information of the target vehicle is prevented from being queried by the way of setting the first operation information label to be empty, so that the privacy of the owner of the target vehicle is ensured.
In one embodiment of the present invention, for further explanation and limitation, the determining the second operation information tag from the vehicle information classification tags according to the service transaction information includes:
matching a target service group from a service group mapping relation set according to the service transaction information;
and determining the vehicle information tag matched with the information category in the target service packet in the vehicle information classification tag as a second operation information tag.
In the embodiment of the invention, the service group mapping relation set comprises mapping relations between different vehicle information groups and different preset service levels. Wherein the vehicle information packet includes a vehicle information classification tag of at least one vehicle information category, and the preset service level may include a plurality of preset service levels. For example, a first predetermined service level corresponds to a first vehicle information packet including two categories of vehicle information classification tags, and a second predetermined service level corresponds to a second vehicle information packet including three categories of vehicle information classification tags. The first vehicle information packet may also include a determined vehicle information classification tag, for example, the first vehicle information packet includes a maintenance type information tag and an accident type information tag, and the first vehicle information packet includes an insurance type information tag, a violation type information tag and a transaction type information tag. In addition, the different vehicle information groups can also comprise classification labels corresponding to vehicle residual value evaluation reports, vehicle purchasable evaluation reports and the like based on the vehicle information of the multiple categories so as to meet the query requirements of different users on the vehicle information. The vehicle information is classified and grouped to form service commodities of the vehicle information, so that flexible and diversified service of vehicle information inquiry is realized, the requirements of different vehicle information inquiry users are met, and the user experience is improved.
For further explanation and limitation, in one embodiment of the present invention, the determining the target block link point from the block chain node according to the key information includes:
analyzing the key information to determine the user category of the user requesting to send out;
if the user category is a first user category, acquiring a historical accounting category of the user, and determining a blockchain node matched with the historical accounting category in the accounting blockchain nodes as a target blockchain node;
and if the user category is the second user category, acquiring login attribute information of the user, and matching a query blockchain node from the query blockchain nodes according to the login attribute information to serve as a target blockchain node.
In the embodiment of the invention, the user categories comprise a first user category and a second user category, wherein the first user category is a user with accounting authority, and the key type is a private key. The second user category is a user with vehicle information inquiry authority, and the key type is a public key. For the first user category, since there are multiple billing blockchain nodes, and each user is typically only authorized to bill the billing blockchain node of one category, for example, a user affiliated with a vehicle management station is only able to operate the billing blockchain node corresponding to the vehicle management station, so that it is necessary to match the billing blockchain node category according to the history of the user to determine the billing blockchain node that the user is able to operate. In addition, a mapping relation between key information and the operation authority of the accounting block chain link point can be pre-constructed, and then the accounting block chain node pointed by the operation authority of the user is determined according to the key information, and the pointed accounting block chain node is used as a target block chain node.
In the embodiment of the invention, the login attribute information can be geographical area information of the user network IP. For the second user category, because the query blockchain nodes supporting the user query may have multiple geographic area distribution, that is, the vehicle information in different geographic areas is stored in the query blockchain nodes in the corresponding areas, in order to improve the query efficiency, the login attribute information may be acquired, the login geographic area of the user is determined according to the login attribute information, and then the query blockchain link points corresponding to the geographic areas matched with the same geographic area are determined as the target blockchain nodes. Of course, the query block link point with the lowest query amount may be determined as the target block chain node according to the query amount of the query block chain node, and the embodiment of the invention is not limited specifically.

if the target blockchain node is an accounting blockchain node, forwarding information operation content and the key information carried by the information operation request to the target blockchain node so that the target blockchain node performs authority verification according to the key information, and when the authority verification result is that the verification is passed, performing accounting processing on the information of the target vehicle according to the information operation content.
In the embodiment of the invention, when the target blockchain node is the billing blockchain node, the information operation is indicated as the billing action on the vehicle information, the information operation content carried by the information operation request needs to be acquired, and billing is performed according to the information operation content. For example, the target block link point corresponds to an accounting node of an authorized repair shop, and the information operation content may be recording operation of vehicle maintenance information, vehicle repair information, and the like, which is not limited in particular. Because the secret key of the accounting blockchain node is a private key, the secret key information needs to be verified to ensure that the operation authority of the current operation user is verified, so that the authenticity and the accuracy of the accounting information are ensured.
In one embodiment of the present invention, for further explanation and limitation, the method further comprises:
forwarding the service transaction information and/or the information operation request to the supervisory blockchain node so that a vehicle information supervisory side performs verification on vehicle information transaction and/or vehicle information operation;
and acquiring a verification result, if the verification result is that the verification result does not pass, generating early warning information for indicating vehicle information transaction and/or vehicle information operation violation, and transmitting the early warning information to a monitoring terminal.
In the embodiment of the invention, the blockchain node further comprises a supervision blockchain node, and the node corresponds to a supervision side of the information query service. When the target blockchain node is a query blockchain node, the service transaction information and/or the information operation request are/is verified based on the first preset verification condition by sending the service transaction information and/or the information operation request to the supervision blockchain node. The first preset verification condition may include a service transaction amount threshold, a vehicle information classification tag corresponding to a service transaction, and the like, which is not limited in particular. If the service transaction information or the information operation request does not meet the corresponding preset verification conditions, the current vehicle information inquiry service transaction is indicated to have illegal operation. When the target blockchain node is a billing blockchain node, the information operation request is verified based on a second preset verification condition by sending the information operation request to the supervising blockchain node. The second preset verification condition may be an operation item such as deletion, addition, modification, etc., or may be customized according to actual application requirements, and the embodiment of the present invention is not specifically limited. For example, the vehicle information of the blockchain node of the vehicle management system only allows the increase, and if the information operation content carried in the information operation request comprises the modification operation item, the verification result is considered to be failed verification. After the early warning information is generated, the early warning information is sent to terminal equipment of a supervisory person, namely a monitoring terminal, so that the supervisory person performs corresponding intervention or treatment on the operation behaviors of the current user, and the safety of the vehicle information and the specification of the vehicle information query service are ensured.
