Detailed Description
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.
With the improvement of living standard of people, each family member in many families has a vehicle. Because the vehicle information preferences of the family members for the vehicle are different, some family members want to interact with the vehicle information to meet the requirements of each family member.
However, an effective vehicle information interaction method is not available at present, so that it is very difficult for a user to perform vehicle information interaction, resulting in poor user experience.
In order to solve the above problems, the present embodiment provides a method for providing vehicle information interaction based on a blockchain network, where the blockchain network includes a vehicle management department node, a first operator customer service system node, a second operator customer service system node, a public security bureau node, an official vehicle detection factory node, a traffic management bureau node, and the like, where the vehicle management department node is an originator node. In one embodiment, the vehicle authority node sends originator broadcast information to the blockchain network, the originator broadcast information including the vehicle authority node public key and the vehicle authority node blockchain identification. In another embodiment, the originator broadcast information sent by the vehicle authority node to the blockchain network also contains the official contact means of the vehicle authority, such as the official phone number of the vehicle authority. It should be further noted that the public key of the vehicle administration station node, the block chain identifier of the vehicle administration station node, the official contact way of the vehicle administration station, and other information may be stored in the block chain account book of the block chain network, and the block chain account book may further store the public key and the block chain identifier corresponding to each of the nodes of the first operator customer service system, the second operator customer service system, the public security bureau, the official vehicle inspection plant, the traffic management bureau, and the like.
The embodiment provides a vehicle information interaction method, which is applied to a vehicle management station node, and as shown in fig. 1, the method includes the following steps:
step S101, receiving first system broadcast information from a block chain network.
The first system broadcast information is broadcast information generated and sent by the first operator customer service system in response to the first terminal broadcast information from the first user terminal, and comprises first user information, first vehicle information and a first interaction request.
In one embodiment, after receiving first system broadcast information from a first operator customer service system from a blockchain network, a vehicle management station node acquires first user information, first vehicle information and a first interaction request from the first system broadcast information, and specifically includes:
first, a vehicle management station node queries a block chain account book to obtain a first system public key of a first operator customer service system.
Secondly, the vehicle management station node uses the first system public key to carry out private key signature verification on the first system broadcast information. It should be noted that, the node of the vehicle management station performs private key signature verification on the first system broadcast information, so that the first system broadcast information received by the node of the vehicle management station is ensured to come from the customer service system of the first operator, and user loss caused by counterfeiting of the first system broadcast information by an illegal node is avoided.
And then, after the private key signature passes the verification, the vehicle management station node extracts the first system encrypted information from the first system broadcast information.
And finally, the vehicle management node decrypts the first system encrypted information according to a predetermined algorithm by using a private key of the vehicle management node, and acquires the first user information, the first vehicle information and the first interaction request. It should be noted that, because the first system encrypted information can only be decrypted by the private key of the vehicle management station node, only the vehicle management station node can decrypt the first system encrypted information to obtain the first user information, the first vehicle information, and the first interaction request, thereby preventing the first user interest from being damaged due to the fact that the first user information, the first vehicle information, and the first interaction request are illegally obtained by the illegal node by intercepting the first system broadcast information.
Step S102, receiving second system broadcast information from the block chain network.
The second system broadcast information is broadcast information generated and sent by the second operator customer service system in response to the second terminal broadcast information from the second user terminal, and includes second user information, second vehicle information and a second interaction request.
In one embodiment, after receiving second system broadcast information from a second operator customer service system from a blockchain network, a vehicle management station node acquires second user information, second vehicle information, and a second interaction request from the second system broadcast information, and the specific steps include:
first, the vehicle management station node queries a block chain account book to obtain a second system public key of a customer service system of a second operator.
And secondly, the vehicle management station node performs private key signature verification on the second system broadcast information by using the second system public key. It should be noted that, the node of the vehicle management station performs private key signature verification on the second system broadcast information to ensure that the second system broadcast information received by the node of the vehicle management station comes from the customer service system of the second operator, so as to avoid the second user loss caused by the fact that the illegal node counterfeits the second system broadcast information.
And then, after the private key signature passes the verification, the vehicle management station node extracts the second system encrypted information from the second system broadcast information.
And finally, the vehicle management station node decrypts the second system encrypted information according to a predetermined algorithm by using the private key of the vehicle management station node, and acquires second user information, second vehicle information and a second interaction request. It should be noted that, because the second system encrypted information can only be decrypted by the private key of the vehicle management station node, only the vehicle management station node can decrypt the second system encrypted information to obtain the second user information, the second vehicle information, and the second interaction request, thereby preventing the second user interest from being damaged due to the fact that the illegal node illegally obtains the second user information, the second vehicle information, and the second interaction request by intercepting the second system broadcast information.
And step S103, judging whether the first user information, the first vehicle information, the second user information and the second vehicle information are correct or not based on the prestored information.
The pre-stored information is the file information stored in the vehicle management station node when the vehicle is dropped, and the pre-stored information comprises first user file information, first vehicle file information, second user file information and second vehicle file information. It should be noted that the first user profile information and the first vehicle profile information correspond to each other; the second user profile information and the second vehicle profile information correspond to each other. The first user profile information comprises a first pre-stored user valid certificate number and a first pre-stored user name; the first vehicle file information comprises a first pre-stored license plate number, a first pre-stored engine number and a first pre-stored annual inspection time validity period; the second user profile information comprises a second pre-stored user valid certificate number and a second pre-stored user name; the second vehicle profile information includes a second pre-stored license plate number, a second pre-stored engine number, and a second pre-stored annual inspection time validity period. The first user information comprises a first user valid certificate number and a first user name of the first user; the second user information comprises a second user valid certificate number and a second user name of the second user; the first vehicle information comprises a first license plate number, a first engine number and a first annual inspection time validity period; the second vehicle information includes a second license plate number, a second engine number, and a second annual inspection time validity period.
In one embodiment, the step of the vehicle management station node judging whether the first user information, the first vehicle information, the second user information and the second vehicle information are correct or not based on the pre-stored information comprises the following steps: first, the node of the vehicle management station compares the first user profile information with the first user information. And secondly, when the first pre-stored user valid certificate number, the first pre-stored user name and the first user valid certificate number and the first user name in the first user profile information are correspondingly consistent, the vehicle management station node compares the first vehicle profile information with the first vehicle information. And then, when the first pre-stored license plate number, the first pre-stored engine number and the first pre-stored annual inspection time validity period in the first vehicle file information correspond to and are consistent with the first license plate number, the first engine number and the first annual inspection time validity period in the first vehicle information, the vehicle management station node compares the second user file information with the second user information. And finally, when a second pre-stored user valid certificate number, a second pre-stored user name and a second user valid certificate number and a second user name in the second user profile information are correspondingly consistent, the vehicle management department node compares the second vehicle profile information with the second vehicle information, and when a second pre-stored license plate number, a second pre-stored engine number and a second pre-stored annual inspection time validity period in the second vehicle profile information are correspondingly consistent with a second license plate number, a second engine number and a second annual inspection time validity period in the second vehicle information, the vehicle management department node judges that the first user information, the first vehicle information, the second user information and the second vehicle information are correct. Otherwise, the node of the vehicle management station judges that the first user information, the first vehicle information, the second user information and the second vehicle information are incorrect. It should be noted that the vehicle management station node determines whether the first user information, the first vehicle information, the second user information and the second vehicle information are correct or not based on the pre-stored information, so that it can be avoided that an illegal node counterfeits the first user information, the second user information, the first vehicle information and/or the second vehicle information to perform vehicle information interaction to cause user loss, and user benefits are guaranteed.
And step S104, when the first user information, the first vehicle information, the second user information and the second vehicle information are correct, whether the first user information, the second user information, the first vehicle information and the second vehicle information accord with preset interaction conditions is judged based on the first interaction request and the second interaction request.
The preset interaction condition is a condition which is preset by a vehicle management node and is required to be met by user information and vehicle information during vehicle information interaction. It should be noted that, different vehicle information interactions are performed, that is, when the interaction requests are different, the preset interaction conditions are different. The first user information comprises a first user valid certificate number and a first user name of the first user; the second user information comprises a second user valid certificate number and a second user name of the second user; the first vehicle information comprises a first license plate number, a first engine number and a first annual inspection time validity period; the second vehicle information includes a second license plate number, a second engine number, and a second annual inspection time validity period.
In one embodiment, when the first interaction request and the second interaction request are requests for exchanging license plate numbers between a first vehicle of a first user and a second vehicle of a second user, the preset interaction condition is that the license plate numbers of the first vehicle and the second vehicle are license plate numbers of the same city, the first vehicle and the second vehicle are vehicles of the same type, and the first user and the second user have a direct relationship. In this embodiment, the step of determining, by the vehicle management station node, whether the first user information, the second user information, the first vehicle information, and the second vehicle information meet the preset interaction condition based on the first interaction request and the second interaction request includes:
firstly, a vehicle management station node extracts a first license plate number and a second license plate number from first vehicle information and second vehicle information respectively, and inquires whether the first license plate number and the second license plate number are license plate numbers of the same city or not.
And secondly, when the first license plate number and the second license plate number are license plate numbers of the same city, the vehicle management station node inquires whether a first vehicle corresponding to the first license plate number and a second vehicle corresponding to the second license plate number are vehicles of the same type, for example, the vehicles are private vehicles of non-operation types.
And thirdly, when the first vehicle and the second vehicle are vehicles of the same type, the vehicle management station node acquires the legal relationship between the first user and the second user based on the first user information and the second user information. The legal relationship is a social relationship, such as an unrelated relationship or an immediate relationship, with legal obligation content of the first user and the second user.
In this embodiment, the step of acquiring the legal relationship between the first user and the second user by the node of the vehicle management station specifically includes: firstly, a vehicle management station node generates relation query broadcast information based on first user information and second user information; specifically, after the public key of the public security bureau node is used for encrypting the first user information and the second user information according to a predetermined algorithm to generate encrypted user information, the public key of the public security bureau node is used for carrying out private key signature on the encrypted user information and the relation query request to generate relation query broadcast information. Secondly, the vehicle management station node sends the relation inquiry broadcast information to a block chain network; then, the vehicle management station node receives the relationship confirmation broadcast information returned by the public security bureau node according to the relationship inquiry broadcast information from the block chain network; the relationship confirmation broadcast message contains a legal relationship of the first user and the second user. And finally, the vehicle management station node acquires the legal relationship between the first user and the second user from the relationship confirmation broadcast information.
And fourthly, when the legal relationship between the first user and the second user is a direct relationship, the vehicle management station node confirms that the first user information, the second user information, the first vehicle information and the second vehicle information accord with preset interaction conditions.
It should be noted that, when the first user information, the first vehicle information, the second user information, and the second vehicle information are correct, the vehicle management station node determines whether the first user information, the second user information, the first vehicle information, and the second vehicle information meet the preset interaction condition based on the first interaction request and the second interaction request, which can ensure that the vehicle information interaction is performed within a legal allowed range, ensure user benefits, and improve user experience.
And step S105, when the first user information, the second user information, the first vehicle information and the second vehicle information accord with preset interaction conditions, generating interaction success broadcast information based on the first user information, the first vehicle information, the first interaction request, the second user information, the second vehicle information and the second interaction request.
The first user information comprises a first user valid certificate number and a first user name of a first user; the second user information comprises a second user valid certificate number and a second user name of the second user; the first vehicle information comprises a first license plate number, a first engine number and a first annual inspection time validity period; the second vehicle information includes a second license plate number, a second engine number, and a second annual inspection time validity period.
In one embodiment, the step of generating, by the vehicle management node, the interaction success broadcast information based on the first user information, the first vehicle information, the first interaction request, the second user information, the second vehicle information, and the second interaction request includes:
firstly, the vehicle management station node generates first vehicle interaction information and second vehicle interaction information according to the first interaction request and the second interaction request. Specifically, the vehicle management station node exchanges a first license plate number contained in first vehicle information with a second license plate number contained in second vehicle information according to a first interaction request and a second interaction request, acquires a first engine number hash value, a first annual inspection time valid period hash value, a second engine number hash value and a second annual inspection time valid period hash value based on a first engine number, the first annual inspection time valid period, the second engine number hash value and the second annual inspection time valid period hash value, and generates first vehicle interaction information and second vehicle interaction information based on the information; the first vehicle interaction information comprises a second license plate number, a first engine number hash value and a first annual inspection time validity period hash value; the second vehicle interaction information includes a first license plate number, a second engine number hash value, and a second annual inspection time validity period hash value.
Then, the vehicle management station node generates interaction success broadcast information based on the first user information, the second user information, the first vehicle interaction information and the second vehicle interaction information. The interactive success broadcast information comprises a first user information hash value, first user part clear text information, first vehicle interaction information, a second user information hash value, second user part clear text information and second vehicle interaction information. It should be noted that the first user information hash value and the first user part plaintext information correspond to the first vehicle interaction information; the second user information hash value and the second user part plaintext information correspond to second vehicle interaction information. The first user information hash value comprises a first user valid certificate number hash value and a first user name hash value; the first user part plaintext information comprises part plaintext information of the first user valid certificate number and part plaintext information of the first user name; the second user information hash value comprises a second user valid certificate number hash value and a second user name hash value; the second user partial plaintext information includes partial plaintext information for a second user's valid certificate number and partial plaintext information for a second user's name.
According to the embodiment, the interactive success broadcast information generated by the vehicle management node does not directly exist in a plaintext form except the first license plate number and the second license plate number. Therefore, even if the illegal node intercepts the successfully-interacted broadcast information, the user information cannot be obtained through the successfully-interacted broadcast information, namely, the vehicle management station node guarantees the user privacy and the vehicle privacy safety through the embodiment, the user benefit is maintained, and the user experience is improved.
Step S106, sending the successful interaction broadcast information to the blockchain network, so that other nodes update the historical storage information according to the successful interaction broadcast information.
The other nodes are nodes for vehicle management in the block chain network, such as official vehicle detection plant nodes and traffic administration nodes. The history storage information is user information stored in the internal database of the other node and vehicle information corresponding to the user information.
In one embodiment, after the node of the vehicle management station sends the successful interaction broadcast information to the blockchain network, other nodes receive the successful interaction broadcast information from the blockchain network, and then the other nodes query the blockchain account book to obtain the public key of the node of the vehicle management station, and perform private key signature verification on the successful interaction broadcast information by using the public key of the node of the vehicle management station. After the private key signature passes verification, other nodes extract a first license plate number and a second license plate number from interactive successful broadcast information, and query an internal database based on the first license plate number and the second license plate number to obtain first historical user information and first historical vehicle information corresponding to the first license plate number and second historical user information and second historical vehicle information corresponding to the first license plate number. And finally, the other nodes calculate the first historical user information, the first historical vehicle information, the second historical user information and the second historical vehicle information, compare the calculated information with a first user information hash value, first user part clear text information, a first engine number hash value, a first annual inspection time validity period hash value, a second user information hash value, second user part clear text information, a second engine number hash value and a second annual inspection time validity period hash value contained in the successfully updated broadcast information, and update the historical storage information by the other nodes when all the values are consistent. It should be noted that, in the updated historical storage information, the first user information corresponds to the second license plate number, the first engine number and the first annual inspection time validity period; the second user information corresponds to the first license plate number, the second engine number, and the second annual check time validity period.
The embodiment provides a vehicle information interaction method, which is applied to a vehicle management station node. The first system broadcast information is broadcast information generated and sent by a first operator customer service system in response to first terminal broadcast information from a first user terminal, and comprises first user information, first vehicle information and a first interaction request; the second system broadcast information is broadcast information generated and transmitted by the second operator customer service system in response to the second terminal broadcast information from the second user terminal, and includes second user information, second vehicle information, and a second interaction request. And secondly, judging whether the first user information, the first vehicle information, the second user information and the second vehicle information are correct or not based on prestored information, and preventing the user interests from being damaged due to the fact that an illegal node pretends to be a user. Then, when the first user information, the first vehicle information, the second user information and the second vehicle information are correct, whether the first user information, the second user information, the first vehicle information and the second vehicle information meet preset interaction conditions or not is judged based on the first interaction request and the second interaction request, so that vehicle information interaction is carried out under the condition that the vehicle information interaction meets legal regulations, and the benefits of users are guaranteed. And finally, when the first user information, the second user information, the first vehicle information and the second vehicle information accord with preset interaction conditions, generating interaction success broadcast information based on the first user information, the first vehicle information, the first interaction request, the second user information, the second vehicle information and the second interaction request, and sending the interaction success broadcast information to the block chain network, so that other nodes update history storage information according to the interaction success broadcast information.
The embodiment also provides a method for vehicle information interaction, which is applied to a first operator customer service system, and as shown in fig. 2, the method includes:
step S201, generating first system broadcast information in response to first terminal broadcast information from a first user terminal.
The first system broadcast information is used for assisting the vehicle management station node to carry out vehicle information interaction and comprises first user information, first vehicle information and a first interaction request. The first terminal broadcast information comprises a first terminal block chain identifier of the first user terminal, first terminal encrypted user information, first terminal encrypted vehicle information and a first interaction request.
In one embodiment, the step of the first operator customer service system generating the first system broadcast information in response to the first terminal broadcast information from the first user terminal comprises:
first, the operator customer service system extracts a first user terminal block chain identifier from first terminal broadcast information. The first terminal broadcast information comprises a first terminal block chain identifier, first terminal encrypted user information, first terminal encrypted vehicle information and a first interaction request;
and secondly, the operator customer service system acquires the first user terminal identification from the first user information list according to the first user terminal block chain identification. Wherein the first user information list is a customer information list stored in a first operator customer service system. It should be noted that the specific steps of the generation process of the first user information list include: after receiving a first short message from a first user terminal, a first operator customer service system writes a first user terminal identifier, a first user terminal block chain identifier and a first user terminal public key contained in the first short message into a first user information list. The first user terminal identification comprises a user mobile phone number.
Then, the operator customer service system obtains a first customer service password based on the first user terminal identifier, and decrypts the first terminal encrypted vehicle information and the first terminal encrypted user information by using the first customer service password to obtain the first vehicle information and the first user information. The first customer service password is a unique password which is stored in a first operator customer service system and corresponds to the first user. The first vehicle information includes a first license plate number, a first engine number, and a first annual inspection time validity period. The first user information includes a first user valid certificate number and a first user name. It should be noted that only the first user can encrypt the first vehicle information on the first user terminal by using the first customer service password to generate the first terminal encrypted vehicle information, so that when the first operator customer service system decrypts the first terminal encrypted vehicle information by using the first customer service password to obtain the first vehicle information, it is indicated that the first terminal broadcast information containing the first terminal encrypted vehicle information is sent by the first user, thereby avoiding user loss caused by an illegal user sending a short message by using a user terminal, maintaining user benefits, and improving user experience.
Finally, the first operator customer service system generates first system broadcast information based on the first vehicle information, the first user information, and the first interaction request. Specifically, first, to avoid that an illegal node captures the first system broadcast information and then obtains first vehicle information and first user information, the first operator customer service system encrypts the first user information, the first vehicle information, and the first interaction request according to a pre-agreed algorithm by using a public key of a node of a vehicle administration office, and generates first system encrypted information. And finally, in order to avoid user loss caused by illegal information sent by an illegal node serving as a first operator customer service system, the first operator customer service system carries out private key signature on the first system encrypted information by using a first system private key of the first operator customer service system to generate first system broadcast information.
Step S202, sending first system broadcast information to a block chain network, so that a vehicle management station node receives first system broadcast information and second system broadcast information from a second operator customer service system from the block chain network, judging that the first user information, the first vehicle information, the second user information and the second vehicle information are correct based on prestored information, and generating and sending interactive success broadcast information to the block chain network based on the first user information, the first vehicle information, the first interactive request, the second user information, the second vehicle information and the second interactive request after judging that the first user information, the first vehicle information, the second user information and the second vehicle information accord with preset interactive conditions based on the first interactive request and the second interactive request.

first, a first vehicle management acquisition module queries a block chain account book to acquire a first system public key of a first operator customer service system.
And secondly, the first vehicle management department verification module performs private key signature verification on the first system broadcast information by using the first system public key. It should be noted that, the private key signature verification performed by the first system broadcast information by the first vehicle management station verification module can ensure that the first system broadcast information received by the vehicle management station node comes from the first operator customer service system, thereby avoiding user loss caused by the fact that the first system broadcast information is forged by an illegal node.
Then, after the private key signature passes the verification, the first vehicle management department extracts the first system encrypted information from the first system broadcast information.
And finally, the first vehicle management department decryption module decrypts the first system encrypted information by using the private key of the vehicle management department node according to a predetermined algorithm to obtain the first user information, the first vehicle information and the first interaction request. It should be noted that, because the first system encrypted information can only be decrypted by the private key of the vehicle management station node, only the vehicle management station node can decrypt the first system encrypted information to obtain the first user information, the first vehicle information, and the first interaction request, thereby preventing the first user interest from being damaged due to the fact that the first user information, the first vehicle information, and the first interaction request are illegally obtained by the illegal node by intercepting the first system broadcast information.
