The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.
The vehicle information protection method and device provided by the embodiment of the invention consider that in vehicle management services such as vehicle number plate interchange, related vehicle information is difficult to record so as to facilitate subsequent information query and information tracing, and meanwhile, the vehicle information is required to be ensured not to be leaked. In view of the above, a method and an apparatus for protecting vehicle information are provided, in which an operator node is introduced, the operator node performs identity verification on a user node, and sends vehicle number plate interchange information of the user node passing the identity verification to a vehicle management node, the vehicle management node performs a vehicle number plate interchange operation, and updates vehicle management data of the vehicle management node by using the generated vehicle number plate interchange update information, thereby achieving the purpose of recording related vehicle information, facilitating subsequent information query and information tracing, and simultaneously ensuring that the vehicle information is not leaked.
Fig. 1 is a flowchart of a vehicle information protection method according to a first embodiment of the present invention, applied to a vehicle management node. As shown in fig. 1, the vehicle information protection method may include the steps of:
and step S101, receiving the vehicle number plate interchange information corresponding to the user node sent by the operator node.
The vehicle number plate interchange information is obtained by decrypting a vehicle number plate interchange request by an operator node according to a pre-agreed algorithm by using an operator customer service password preset by the user node, the vehicle number plate interchange request is a message which is sent to the operator node after the user node encrypts the vehicle number plate interchange information by using the operator customer service password, and the user node is a user node passing the identity verification of the operator node.
Generally, when a user node has a requirement for exchanging vehicle license plates, the user node directly sends a request for exchanging vehicle license plates or information for exchanging vehicle license plates to a vehicle management node, the vehicle management node judges whether the operation for exchanging vehicle license plates of the user node can be executed according to a rule for exchanging vehicle license plates, and the operation for exchanging vehicle license plates of the user node is executed when the request for exchanging vehicle license plates or the information for exchanging vehicle license plates meets the rule for exchanging vehicle license plates. In this way, there is a risk of leakage of the vehicle number plate interchange information, and it is cumbersome to update the corresponding vehicle information after the vehicle number plate interchange operation is performed. In consideration of the fact that an operator can deposit a large amount of real and effective user information when a user transacts services, the vehicle information protection method provided by the embodiment introduces the operator node, fully utilizes the user information prestored in the operator node, firstly carries out identity verification on the user node, and then sends the vehicle license plate interchange information of the user node passing the identity verification to the vehicle management node; meanwhile, the block chain technology is used, corresponding block contents are correspondingly updated by the vehicle management node after the vehicle number plate interchange operation is executed, the subsequent vehicle information tracing and vehicle information query are facilitated, and the vehicle information can be effectively prevented from being leaked by the adoption of the modes of information encryption, information signature and the like of the block chain technology.
In one embodiment, a vehicle management node is used as an originator node, and an operator node, a user node and a vehicle assistant node are combined to form a block chain network; the vehicle management nodes are nodes corresponding to vehicle management mechanisms such as a vehicle administration department and the like, the vehicle assistant management nodes are nodes corresponding to vehicle assistance management mechanisms such as an official vehicle detection mechanism and a traffic management mechanism and the like, the operator nodes are nodes corresponding to a communication operator, and the user nodes are nodes corresponding to individual users. The vehicle management node publishes a created block in the block chain network, wherein the created block comprises block chain identifications and public keys corresponding to the vehicle management node, the operator node and the vehicle co-management node. For the user node, the user node generates the block chain identifier, the public key and the private key of the user node locally, and then sends the block chain identifier and the public key of the user node to the affiliated operator node by sending short messages or other modes through a mobile switching network by using the mobile phone number of the user node. After receiving the block chain identification and the public key sent by the user node, the operator node binds the block chain identification and the public key with the mobile phone number of the user node, associates the block chain identification and the public key of the user node with the identity information of the user node reserved in the operator node through the mobile phone number, and writes the block chain identification and the public key of the user node into a user information block of the operator node, wherein the user information block comprises the mobile phone number, the block chain identification and the public key of the user node and the identity information such as the name and the identity number of the operator node reserved in the user node.
When the user node wants to exchange the vehicle numbers of the first vehicle and the second vehicle under the name of the user node, the user node sends a vehicle number plate exchange request to the operator node. Specifically, the user node encrypts the name and the identity card number of the user node according to a predetermined algorithm by using a preset operator customer service password to obtain encrypted identity information of the user node; encrypting a first vehicle number plate, a first vehicle engine number and first vehicle annual inspection information corresponding to a first vehicle by adopting the same method to obtain encrypted information of the first vehicle; similarly, a second vehicle number plate, a second vehicle engine number and second vehicle annual inspection information corresponding to a second vehicle are encrypted to obtain encrypted information of the second vehicle, then a vehicle number plate interchange request is generated based on the encrypted identity information, the encrypted information of the first vehicle, the encrypted information of the second vehicle, the block chain identification of the user node and the vehicle number plate interchange mark, and the vehicle number plate interchange request is broadcasted in the block chain network.
After receiving the vehicle number plate interchange request broadcast by the user node, the operator node learns the requirement of exchanging the vehicle number plate of the user node according to the vehicle number plate interchange mark in the vehicle number plate interchange request, and then carries out identity verification on the user node. Specifically, the operator node determines whether the identity information of the user node is stored in the user information block of the operator node according to the block chain identifier of the user node in the vehicle number plate interchange request. When the operator node determines that the identity information of the user node is stored in the user information block of the operator node, the operator node inquires an operator customer service password preset by the user node in the operator node, decrypts the encrypted information in the vehicle number plate interchange request according to a pre-agreed algorithm by using the operator customer service password, and obtains decrypted vehicle number plate interchange information, wherein the decrypted vehicle number plate interchange information comprises the name and the identity number of the user node, a first vehicle number plate corresponding to a first vehicle, a first vehicle engine number, first vehicle annual inspection information, a second vehicle number plate corresponding to a second vehicle, a second vehicle engine number and second vehicle annual inspection information. And the operator node checks whether the name and the identity card number in the decrypted vehicle number plate interchange information are consistent with the name and the identity card number corresponding to the mobile phone number of the user node in the operator customer service system, and if the name and the identity card number are consistent, the user node passes the identity authentication. The operator node encrypts the vehicle number plate interchange information according to a predetermined algorithm by using a public key of the vehicle management node, signs the encrypted vehicle number plate interchange information by using a private key of the operator node, and broadcasts the vehicle number plate interchange information in the blockchain network.
And the vehicle management node receives the vehicle number plate interchange information corresponding to the user node broadcasted by the operator node in the block chain network.
It should be noted that the operator service password is used by the user node when the user node generates the vehicle number plate interchange request, the operator service password is also used by the operator node when the user node decrypts the vehicle number plate interchange request, and the operator service password is set by the user node, so that higher security of the information encrypted based on the operator service password can be ensured.
And S102, judging whether the vehicle number plate interchange operation of the user node meets a preset vehicle number plate interchange rule or not based on the vehicle number plate interchange information.
The vehicle number plate interchange rule is a rule set according to specific vehicle number plate interchange business provision and related legal regulations. Under the current situation, two vehicles belonging to the same place and both of which are non-operation types are allowed to exchange the number plates of the vehicles under the same user name.
It can be understood that the vehicle number plate interchange rule can be adjusted and updated according to the service requirement or service change.
In one embodiment, the determining whether the vehicle number plate interchange operation of the user node satisfies a preset vehicle number plate interchange rule based on the vehicle number plate interchange information includes:
firstly, the vehicle management node extracts a first vehicle number plate and a second vehicle number plate from the vehicle number plate interchange information, wherein the first vehicle number plate is a vehicle number plate corresponding to a first vehicle, the second vehicle number plate is a vehicle number plate corresponding to a second vehicle, and the first vehicle and the second vehicle are vehicles to be subjected to vehicle number plate interchange. After obtaining a first vehicle number plate and a second vehicle number plate, a vehicle management node queries users corresponding to a first vehicle and a second vehicle from a vehicle management database prestored in the vehicle management node, judges whether the first vehicle and the second vehicle belong to the same user, further queries the attribution of the first vehicle and the second vehicle and the operation type of the first vehicle and the second vehicle when the first vehicle and the second vehicle belong to the same user, and obtains query results of a first attribution, a second attribution, a first operation type and a second operation type, wherein the first attribution is the attribution of the first vehicle, the first operation type is the operation type of the first vehicle, the second attribution is the attribution of the second vehicle, and the second operation type is the operation type of the second vehicle. And finally, the vehicle management node judges whether the vehicle number plate interchange operation of the user node meets the vehicle number plate interchange rule or not according to the first attribution, the second attribution, the first operation type and the second operation type. If the preset vehicle number plate interchange rule is that the vehicles exchanging the vehicle number plates belong to the same attribution place and the vehicles exchanging the vehicle number plates are all non-operation type vehicles, when the first attribution place is the same as the second attribution place and the first operation type and the second operation type are both non-operation types, the fact that the vehicle number plate interchange operation of the user node meets the vehicle number plate interchange rule is judged.
