Detailed Description
The following detailed description of embodiments of the present application will be made with reference to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present application, are given by way of illustration and explanation only, and are not intended to limit the present application. It will be apparent to one skilled in the art that the present application may be practiced without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present application by illustrating examples thereof.
To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
Fig. 1 shows a flow chart of a vehicle gifting method in an embodiment of the present application. The vehicle gifting method is applicable to an operator server. As shown in fig. 1, the vehicle gifting method includes:
The first node is a node corresponding to the donor, and the second node is a node corresponding to the donated party. It should be noted that, if the first node and the second node do not belong to the same operator, the legitimacy of the first node and the second node may be verified respectively through different operator servers. For example, a first operator server is used to verify the validity of a first node, and a second operator server is used to verify the validity of a second node.
In some implementations, the verifying whether the first node is a legitimate node according to the blockchain information of the first node in step 101 can be implemented as follows: searching a user node block chain information list according to the block chain information of the first node to obtain an operator customer service password corresponding to the first node; decrypting the first encryption result by using the operator customer service password and a preset algorithm to obtain user identity information of the gifting party and information of the gifted vehicle; comparing the user identity information of the donator with the pre-stored user identity information of the donator to obtain a comparison result; and if the comparison results are the same, determining that the first node is a legal node.
The user identity information may include information such as an identification number of the user, a user name, and the like. The information donated to the vehicle may include: an annual check time validity period (e.g., validity period is 5/31/2020), a license plate number of the donated vehicle (e.g., jing ABC666), and an engine number of the donated vehicle (e.g., 123456789), among others. The user node blockchain information list is information of each node in a blockchain network stored in advance, and specifically may include information such as a blockchain identifier, a public key, a private key, and an operator service password corresponding to each node. The information included in the user node blockchain information list is only an example, and may be specifically set according to an actual situation, and the information included in other non-described user node blockchain information lists is also within the protection scope of the present application, and is not described herein again.
In some implementations, before step 101, the method further includes: and obtaining a donation request message sent by the first node from the blockchain network, wherein the donation request message comprises a first encryption result, blockchain information of the first node and a vehicle donation identifier, and the first encryption result is a result of encrypting the information of the first node and the information donated to the vehicle by the first node by using a corresponding operator service password and a preset algorithm.
For example, when the gifting party wants to donate the license plate and the vehicle of the vehicle M under its own name to the gifted party, the gifting party sends a gifting request message to the blockchain network through the first node, so that the operator server corresponding to the first node receives the gifting request message and verifies the relevant information in the gifting request message.
And step 102, if the first node and the second node are both legal nodes, sending a donation confirmation message to the second node.
When the second node receives the donation confirmation message, the donated party determines whether to accept the donation, and specifically, the donation confirmation message includes information such as the first node information, the second node information, an identifier indicating whether the donation is willing to be accepted, an age date of the donated vehicle, a license plate number of the donated vehicle, and an engine number of the donated vehicle, so that the donated party can conveniently verify the information of the donated vehicle, according to identity information of the donated party, and the like.
In some implementations, step 102 can be implemented as follows: if the first node and the second node are both legal nodes, sending a donation confirmation message to the second node through the mobile switching network; the donation confirmation message comprises information of the first node, information of the second node, information of the donated vehicle and identification of whether the donation is willing to be accepted, and the information of the donated vehicle comprises an annual inspection time validity period of the donated vehicle, a license plate number of the donated vehicle and engine information of the donated vehicle.
The donation confirmation message is sent to the second node through the mobile switching network, so that the second node can obtain the donation confirmation message quickly. In specific implementation, the donation confirmation message may also be sent to the second node through the blockchain network, so as to ensure the security of the information.
And 103, responding to the willing-to-accept donation message fed back by the second node, generating and sending a donation confirmation broadcast message to the blockchain network according to the information of the first node, the information of the second node and the information of the donated vehicle.
When the vehicle management node obtains the donation confirmation broadcast message, the information of the first node, the information of the second node, and the information donated to the vehicle in the donation confirmation broadcast message may be obtained by parsing. For example, the identity information of the gifting party, the identity information of the gifted party, the hardware device information and the license plate number of the gifted vehicle, and the like are obtained. The relationship between the donor and the recipient is then confirmed so that the relationship satisfies the requirements associated with vehicle gifting (e.g., in "a business for remote access," it is specified that the owner can donate his or her vehicle to another person, but the recipient must have a driving license or the like within the validity period, and the donor and the recipient are in a relationship of relativity). The gifted vehicle is then gifted to the gifted party in accordance with the relationship information between the gifting party and the gifted party.
In this embodiment, whether the first node is a legal node is verified through the blockchain information of the first node, whether the second node is a legal node is verified through the blockchain information of the second node, and when the first node and the second node are both legal nodes, the donation confirmation message is sent to the second node to obtain the willingness acceptance donation message fed back by the second node. The identity correctness of the first node and the second node is ensured. When the information of the second node fed back and willing to accept the donation is obtained, a donation confirmation broadcast message is generated and sent to the block chain network according to the information of the first node, the information of the second node and the information of the donated vehicle, so that the traffic control center node determines the relationship information between the donation party and the donated party and donates the donated vehicle to the donated party according to the relationship information. The safety of the privacy information of the car owner is guaranteed, the vehicle is prevented from being given to wrong users, and the user experience degree is improved.
Fig. 2 shows a schematic flow chart of a vehicle gifting method in a further embodiment of the present application. The vehicle gifting method is applicable to an operator server. As shown in fig. 2, the vehicle gifting method includes:
Wherein the blockchain message includes blockchain information of the first node and a mobile network identification of the first node. It should be noted that the blockchain information of the first node is generated by the first node itself and is not approved by other nodes in the blockchain network, so that the first node needs to send the blockchain information of the first node and the mobile network identifier of the first node to the operator server in a mobile switching network manner, so that the operator server verifies the information of the first node through the blockchain network, and the first node can conveniently use the blockchain network subsequently.
For example, the Mobile network identifier may be a Subscriber Identity Module (SIM), an International Mobile Subscriber Identity (IMSI), and the like, and the above-mentioned Mobile network identifier is only an example, and may be specifically set according to an actual Mobile network type, and other Mobile network identifiers not described are also within the protection scope of the present application, and are not described herein again.
It should be noted that, by binding the blockchain information of the first node, the mobile network identifier corresponding to the first node, and the user identity information of the donor, the correctness of the information of the first node can be ensured, and the correctness of the information of the first node can be verified in real time when communication is performed in the blockchain network. For example, it can be known from the mobile network identifier corresponding to the first node and the user identity information of the donor that the donor corresponding to the first node is the mobile network identifier transacted for the first node in the operator server by means of real name system, and therefore, the first node is the node authenticated by the operator server. And the first node can be ensured to be capable of communicating with other nodes in the blockchain network through the blockchain information of the first node.
And step 204, writing the binding information into a user node block chain information list.
The user node block chain information list comprises a mobile network identifier corresponding to the first node, block chain information of the first node and user identity information of a donor. Specifically, the user node block chain information list may further include information such as a public key and a private key of each node, and an operator service password corresponding to each node.
In step 206, if it is determined that the first node and the second node are both legitimate nodes, a donation confirmation message is sent to the second node.
Step 207, in response to the willing to accept donation message fed back by the second node, generating and sending a donation confirmation broadcast message to the blockchain network according to the information of the first node, the information of the second node and the information of the donated vehicle.
It should be noted that steps 205 to 207 in this embodiment are the same as steps 101 to 103 in the previous embodiment, and are not described again here.
In this embodiment, the binding information is generated by binding the block chain information of the first node, the mobile network identifier corresponding to the first node, and the user identity information of the donor, so that when the first node communicates with other nodes in the block chain network, the validity of the first node can be confirmed in real time, and the first node can perform information interaction in the block chain network. When the information of the second node fed back and willing to accept the donation is obtained, a donation confirmation broadcast message is generated and sent to the block chain network according to the information of the first node, the information of the second node and the information of the donated vehicle, so that the traffic control center node determines the relationship information between the donation party and the donated party and donates the donated vehicle to the donated party according to the relationship information. The safety of the privacy information of the car owner is guaranteed, the vehicle is prevented from being given to wrong users, and the user experience degree is improved.
Fig. 3 shows a flow chart of a vehicle gifting method in a further embodiment of the present application. The vehicle donation method can be applied to a vehicle management station node server. As shown in fig. 3, the vehicle gifting method includes:
The donation confirmation broadcast message includes information of a first node, which is a node corresponding to the donating party, information of a second node, which is a node corresponding to the donated party, and information of the donated vehicle.
For example, the information of the first node may include identity information (e.g., identification number, name, etc.) of a donor corresponding to the first node, an identification of an operator server corresponding to the first node, block chain information of the first node, and the like. The information of the second node may include identity information (e.g., identification number, name, etc.) of a donor corresponding to the second node, an identification of an operator server corresponding to the second node, block chain information of the second node, etc. The information donated to the vehicle may include: an annual check time validity period given to the vehicle, a license plate number given to the vehicle, an engine number given to the vehicle, and the like.
In particular, the information of the first node and the information of the second node may be sent to the public security node through the blockchain network, so that the public security node may obtain the relationship information between the donating party and the given party (for example, the donating party and the given party are related, or the donating party and the given party are related directly) by searching the household database inside the public security node. After obtaining the relationship information between the donating party and the given party, the public security node feeds the relationship information back to the operator server through the block chain network.
It should be noted that the donated vehicle may be donated to the donated party when the relationship information between the donator and the donated party satisfies the condition for vehicle donation (for example, in "a transaction for remote access", it is specified that the owner of the vehicle may donate his/her vehicle to another person, but the donated party must have a driving license or the like within the validity period, and the donator and the donated party are in a relationship). When the relationship information between the giftor and the gifted party cannot satisfy the condition for vehicle gifting, the process is accepted, the gifted vehicle is rejected from being gifted to the gifted party, and rejection information is fed back to the first node.
In some implementations, step 303 can be implemented as follows: the gifted vehicle is gifted to the gifted party if the gifting party and the gifted party are determined to be in a relationship.
It should be noted that the relationship may be a direct relationship or a collateral relationship.
In some implementations, after step 303, the method further includes: carrying out Hash operation on the information of the first node to generate a first Hash value; performing hash operation on the information of the second node to generate a second hash value; performing a hash operation on the given vehicle information to generate a third hash value; and generating and sending a successful donation broadcast message to the blockchain network according to the first hash value, the second hash value, the third hash value, the blockchain information of the first node and the blockchain information of the second node, so that the vehicle inspection plant node server obtains and verifies the information in the successful donation broadcast message, changes the owner of the donated vehicle from the donator to the donator, and records the changed information.
The Hash operation is carried out on the information of the first node, the information of the second node and the information of the given vehicle, so that the safety of information transmission in the blockchain network can be ensured, and the situation that the third-party equipment obtains privacy information is avoided.
In the embodiment, the relationship information between the donating party and the given party is obtained by querying the public security node according to the information of the first node and the information of the second node; and donates the given vehicle to the donated party according to the relationship information. The vehicle donation process is guaranteed to meet relevant national regulations, and at the same time, the vehicle to be donated to the wrong user is avoided.

Wherein initiating the broadcast message comprises: the block chain identifier of the node server 601 of the vehicle management department, the public key of the node server 601 of the vehicle management department, the block chain identifier of the node server 602 of the first operator, the public key of the node server 602 of the first operator, the block chain identifier of the node server 603 of the second operator, the public key of the node server 603 of the second operator, the block chain identifier of the node server 604 of the public security, the public key of the node server 604 of the public security, the block chain identifier of the node server 607 of the vehicle inspection factory and the public key of the node server 607 of the vehicle inspection factory.
Specifically, fig. 7 shows a flowchart of a method of operating the vehicle gifting system in the embodiment of the present application. As shown in fig. 7, the method specifically includes the following steps.
In step 701, the first terminal node 605 locally generates first block chain information, and then sends the first node information to the first operator node server 602 in a short message manner in the mobile switching network.
The first node information includes first blockchain information of the first terminal node 605 and a mobile network identifier (e.g., a mobile phone number, etc.) of the first terminal node 605, and the first blockchain information includes a blockchain identifier of the first terminal node 605 and a public/private key of the first terminal node 605.
Meanwhile, the second terminal node 606 locally generates second block chain information, and then sends the second node information to the second operator node server 603 in a short message manner in the mobile switching network. The second node information includes second blockchain information of the second terminal node 606 and a mobile network identifier (e.g., a mobile phone number, etc.) of the second terminal node 606, and the second blockchain information includes a blockchain identifier of the second terminal node 606 and a public/private key of the second terminal node 606.
Meanwhile, the second operator node server 603 obtains the second block chain information of the second terminal node 606 and the mobile phone number of the second terminal node 606 in a short message manner in the mobile switching network, and queries the operator database by using the mobile phone number as an index to obtain the user identity information of the given party; and then binding the second blockchain information, the mobile phone number of the second terminal node 606 and the user identity information of the donated party to generate binding information, and writing the binding information into the user node blockchain information list.
The donating side has the service password of the first operator node server 602, and the receiving side has the service password of the second operator node server 603.
In step 703, the donor wants to donate the license plate and the vehicle of the vehicle M under its own name to the recipient, and the donor sends a donation request message to the blockchain network through the first terminal node 605, so that the first operator node server 602 obtains the donation request message.
Wherein the gifting request message includes the first encryption result, the blockchain information of the first terminal node 605, and the vehicle gifting identification. The first encryption result is a result of the first terminal node 605 encrypting the first node information, the second node information, the validity period of the annual check time of the vehicle M (for example, the validity period is 2020, 5, 31), the license plate number of the vehicle M (for example, kyo ABC666) and the engine number of the vehicle M (for example, 123456789) using the service password and the preset algorithm of the first operator node server 602. The first node information includes identity information of the donating party (e.g., an identification number of the donating party, a name of the donating party, etc.). The second node information includes identity information of the gifted party (e.g., the licensee's identification number, the name of the gifted party, etc.) and the mobile phone number of the gifted party, etc.
It should be noted that, before sending the gifting request message, the gifting request message needs to be signed by using the private key of the first terminal node 605 to ensure the security of the gifting request message.
The pre-stored user identification information of the donating party is the user identification information of the donating party corresponding to the mobile phone number of the donating party.
In step 705, the first carrier node server 602 sends a donation confirmation message to the blockchain network, so that the second carrier node server 603 obtains the donation confirmation message.
The donation confirmation message comprises first node information, second node information, an identifier indicating whether the vehicle M is willing to accept donation, an annual inspection time validity period of the vehicle M, a license plate number of the vehicle M and an engine number of the vehicle M.
Before sending the donation confirmation message to the blockchain network, the donation confirmation message needs to be encrypted according to a preset algorithm by using the public key of the second operator node server 603, and then the encrypted donation confirmation message needs to be signed by using the private key of the first operator node server 602, so as to ensure the security of the donation confirmation message in the transmission process.
In step 706, the second operator node server 603 obtains the second node information in the donation confirmation message from the blockchain network. By comparing the identity information of the gifted party in the second node information with the identity information of the gifted party stored in the database of the second operator node server 603 itself, and comparing the mobile phone number of the gifted party in the second node information with the mobile phone number of the gifted party stored in the database of the second operator node server 603 itself, if both are determined to be correct, a short message is sent to the mobile phone number of the gifted party through the mobile switching network to determine whether the gifted party is willing to accept gifting.
In a specific implementation, the second operator node server 603 may forward the donation confirmation message to the second terminal node 606, and may send the donation confirmation message in a short message manner in a mobile switching network, or in a block chain network manner.
In step 707, the second terminal node 606 obtains a gifting confirmation message, and when the gifted party confirms the willingness to accept the gifting of the vehicle M, feeds back a willingness to accept gifting message to the second operator node server 603.
In step 708, when obtaining the message willing to accept the donation fed back by the second terminal node 606, the second operator node server 603 generates and sends a donation confirmation broadcast message to the blockchain network according to the first node information, the second node information, the valid period of the annual inspection time of the vehicle M, the license plate number of the vehicle M, and the engine number of the vehicle M, so that the vehicle management station node server 601 obtains the donation confirmation broadcast message.
Wherein the donation confirmation broadcast message includes the first node information, the second node information, the annual check time validity period of the vehicle M, the license plate number of the vehicle M, and the engine number of the vehicle M.
It should be noted that, since the mobile phone number and the identification card information of the gifted party are authenticated by the real name in the second operator node server 603, the correctness of the identification information of the gifted party can be ensured.
In step 709, the node server 601 of the vehicle management station verifies the first node information and the second node information after obtaining the donation confirmation broadcast message, and generates a relationship query message according to the first node information and the second node information when the verification passes.
Specifically, the node server 601 of the vehicle administration office queries the database according to the engine number of the vehicle M in the donation confirmation broadcast message to confirm that the validity period of the annual check time of the vehicle M, the license plate number of the vehicle M, and the engine number of the vehicle M are all correct, and determines that the identity information of the donating party and the given party is all correct by obtaining that the current owner of the vehicle M is the donating party.
In step 710, the node server 601 of the vehicle management station sends a relationship query message to the blockchain network, so that the public security node server 604 obtains the relationship query message.
The relationship query message comprises first node information and second node information.
In step 711, the public security node server 604 searches the account database to determine that the donor corresponding to the first node information and the recipient corresponding to the second node information are related (or directly related), which meets the requirement of vehicle donation. The police node server 604 then generates a relationship query response message based on the relationship information between the donating and the given parties.
In step 712, the police node server 604 sends a relationship query response message to the blockchain network, so that the node server 601 of the vehicle management station obtains the relationship information between the donating party and the given party.
In step 713, the node server 601 of the vehicle authority determines that the vehicle M and the license plate of the vehicle M can be donated to the transferee after obtaining the relationship information between the donator and the transferee. Meanwhile, a donation success broadcast message is sent to the blockchain network, so that the vehicle inspection shop node server 607 obtains the donation success broadcast message.
The donation success broadcast message includes the first hash value, the second hash value, the third hash value, the blockchain information of the first terminal node 605, and the blockchain information of the second terminal node 606. The first hash value is obtained by performing hash operation on the identity card information of the donator and the full name of the donator. The second hash value is obtained by hashing the identification card information of the transferee and the full name of the transferee. The third hash value is a hash value obtained by performing hash operation on the license plate number and the engine number of the vehicle M. In particular, the successfully gifted broadcast message may further include digital information of the digits of the plaintext of the identification card of the gifting party and text information of 1-2 plaintext of the name of the gifting party.
In step 714, when the vehicle inspection factory node server 607 obtains the successful donation broadcast message, it verifies the information in the successful donation broadcast message, changes the owner of the vehicle M from the donating party to the given party, and records the changed information.
For example, the change information may include: the owner information of the vehicle M is changed to the presented party. So as to facilitate subsequent information inquiry.
It should be noted that, when the message is sent to the blockchain network in the above steps, the message needs to be encrypted; when the receiving end obtains the encrypted transmission message from the blockchain network, the receiving end also needs to decrypt the transmission message by using the corresponding key. To ensure the security of the message content.
In this embodiment, different operator node servers verify authenticity of identities of users of respective services, and bind user identity information and block chain information of a terminal node, thereby facilitating verification of validity of the terminal. The privacy of the user is guaranteed, meanwhile, the donation relationship of the vehicle, the information of the donator and the information of the donated party can be recorded through the block chain, the relationship between the donator and the donated party is guaranteed to be in accordance with vehicle donation conditions, tracing and inquiring of the vehicle donation process are facilitated, benefits of the user are guaranteed, safe and reliable development of the block chain is promoted, and user experience is improved.
