[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0024] In the description of the present invention, it should be noted that the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0025] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0027] For ease of understanding, a method for verifying the information security of a ride-hailing vehicle provided by an embodiment of the present invention is first described in detail. The method is applied to a server, which is connected to a pre-established two-layer blockchain network and a user terminal, respectively. The user terminal includes a ride-hailing vehicle platform terminal. The pre-established two-layer blockchain network can be found in Figure 1As shown, the pre-established two-layer blockchain network includes an upper layer and a lower layer, the upper layer is a driver chain formed by driver blocks, and the lower layer is a car-hailing chain formed by car-hailing blocks; wherein each driver block includes a vehicle link, which corresponds to the corresponding car-hailing block; similarly, the car-hailing block also includes a driver link, which corresponds to the driver block. Through the pre-established two-layer blockchain network, it can be ensured that the driver information and vehicle information (that is, the car-hailing information) are recorded in a two-layer manner, further improving the security and reliability of the information.

[0028] Further, the online car-hailing information security verification method provided by the embodiment of the present invention can be found in Figure 2 As shown, the method mainly includes the following steps S202 to S210:

[0029] Step S202, obtaining a registration data set of the online car-hailing platform terminal, the registration data set including driver information and vehicle information.

[0030] In one embodiment, since the same driver may register information on multiple platforms, there may be one or more online ride-hailing platform terminals, and the driver information and vehicle information included in the registration data set are corresponding information. It can be understood that when the driver registers information on the online ride-hailing platform, it is necessary to register detailed information on the individual and the vehicle. Therefore, the driver information includes at least name, gender, age, ID number, household registration, driver's license number, driving experience, driving vehicle model, etc. The vehicle information includes at least vehicle signal, age, license plate number, whether it is an electric car, color, etc.

[0031] Step S204: verify the legitimacy of the driver information and vehicle information.

[0032] Information legitimacy verification includes the legitimacy verification of the driver's driving-related information, such as whether the driver has committed non-compliant behaviors such as suspension of business penalties, whether the vehicle information is illegal, whether it has been scrapped, etc. By verifying the legitimacy of driver information and vehicle information, the accuracy and legality of the information can be guaranteed.

[0033] Step S206, generating a driver block based on the driver information after verification of legality, and generating an online car-hailing block based on the vehicle information after verification of legality.

[0034] In one embodiment, after the verification is legal, that is, after determining that the driver information and the corresponding vehicle information are both legal, the generated driver block may include a timestamp, block height, version number, driver specific information, etc., wherein the driver specific information is added with a corresponding credit score, which may be a score evaluated by platform passengers, or a credit score provided by traffic control (such as whether it frequently violates traffic rules, etc.). The online car-hailing block may include a timestamp, block height, vehicle specific information, driver link information, etc., wherein the driver link is the current driver ID of the online car-hailing. It is understandable that there may be two drivers for the same vehicle (such as partners, couples, etc.), so through the driver link of the online car-hailing block, it is possible to adapt to real-time changes in human-vehicle matching, thereby improving the flexibility of information recording.

[0035] Step S208, perform link verification on the driver block and the online car-hailing block, and after the link verification is passed, add the driver block to the driver chain of the pre-established two-layer blockchain network, and add the online car-hailing block to the online car-hailing chain of the pre-established two-layer blockchain network.

[0036] Link verification is to verify whether the driver block has a corresponding link relationship of the online car-hailing block, and whether the online car-hailing block has a driver block of the corresponding chain relationship. It is understandable that if the online car-hailing block corresponding to the driver block is empty, it means that the link verification fails, that is, the driver information does not find the corresponding online car-hailing information. Therefore, in one embodiment, only the blocks that have passed the link verification (that is, the driver blocks and online car-hailing blocks with corresponding link relationships) are added to the pre-established double-layer blockchain network. In addition, in this embodiment, since the blockchain network is a double-layer blockchain network (it can also be a double-layer embedded alliance chain structure), the driver block is added to the driver chain of the pre-established double-layer blockchain network, and the online car-hailing block is added to the online car-hailing chain of the pre-established double-layer blockchain network, and the vehicle link in the driver block corresponds to the driver link of the corresponding online car-hailing block.

[0037] Step S210, perform matching verification on the driver chain and the online car-hailing chain, and determine the matching result.

[0038] In one embodiment, the matching verification may be performed by a consensus algorithm, such as a Practical Byzantine Fault Tolerance (PBFT) consensus algorithm, or other consensus algorithms may be selected based on actual conditions.

[0039] The verification method for the information security of online car-hailing provided by the embodiment of the present invention first obtains the registration data set of the online car-hailing platform terminal, and the registration data set includes driver information and vehicle information, and the driver information corresponds to the vehicle information. Then the driver information and vehicle information are verified for information legitimacy, and after the verification is legal, a driver block is generated based on the driver information, and an online car-hailing block is generated based on the vehicle information. When the driver block and the online car-hailing block are correctly linked, the driver block is added to the driver chain of the pre-established double-layer blockchain network, and the online car-hailing block is added to the online car-hailing chain of the pre-established double-layer blockchain network, that is, the double-layer blockchain network includes the driver chain and the online car-hailing chain corresponding to the driver chain, and the driver chain and the online car-hailing chain are matched and verified, and the matching result is determined to ensure that the driver information and the vehicle information correspond, thereby realizing the verification of the information security of the online car-hailing. The above method can effectively manage the qualifications of online car-hailing drivers in a decentralized manner through a pre-established double-layer blockchain network, greatly reduce the cost of manual verification, and improve the verification effect of the information security of online car-hailing.

[0040] In order to ensure the further accuracy of the driver information and vehicle information, the above-mentioned user terminal may also include a traffic control station platform terminal. Furthermore, the server may obtain the driver's credit information and online car-hailing record information. The driver's credit information and online car-hailing record information are updated information sent to the online car-hailing platform terminal through the traffic control station platform terminal. The driver information is whether the driver has received customer complaints, whether the bill is delayed, etc. The online car-hailing record information includes information such as whether the vehicle is in violation of traffic rules, whether it has undergone annual inspection, whether it has been scrapped, etc. In one embodiment, when the driver violates traffic rules, the violation event / user complaint event information may be sent to the online car-hailing platform terminal through the traffic control station platform terminal, so as to update the corresponding driver information and vehicle information in the registration data set based on the driver's credit information and online car-hailing record information.

[0041] In one embodiment, the driver's specific information is added with a corresponding credit score, and the initial value of the credit score is Score 0 is the initial default score, a n It is a covariant parameter for violation records, which is formulated according to specific circumstances. In addition, driver rating information cannot be shared between different platforms. For example, a driver has driving qualifications on multiple platforms, but information such as bad performance cannot be shared.

[0042] After the above information is verified to be legitimate, the driver block generated based on the driver information may include at least the first timestamp, driver information, and online car-hailing link information; wherein the driver information includes the driver's credit score, and the online car-hailing link information includes the vehicle ID corresponding to the current driver. It can be understood that the correspondence between the driver and the vehicle may include a one-to-one, one-to-many, or many-to-one relationship, and the vehicle ID corresponding to the online car-hailing link information may be one or more. The vehicle information corresponding to the current driver can be associated through the online car-hailing link information.

[0043] The generated online car-hailing block may include at least a second timestamp, vehicle information, and driver link information, wherein the driver link information includes the driver ID corresponding to the current vehicle. Similarly, the driver ID corresponding to the driver link information may be one or more.

[0044] After generating the driver block (also called the driver full node) and the online car-hailing block (also called the vehicle full node), the driver block and the online car-hailing block can be further encrypted. d and the first timestamp d (that is, the timestamp in the driver block) to generate the first public key M d , and by using the first public key M d The corresponding first private key SK d Encrypt and generate signature S d Among them, the following formula can be used to determine: M d =(BMR d ||TimeStamp d );S d =ECC(SK d , M d ). For the online car-hailing block, the block Merkle number BMR can also be used d The second public key is generated by the second timestamp (that is, the timestamp in the online car-hailing block), and the signature is generated by encrypting it with the second private key corresponding to the second public key. The encryption process is the same as the driver block and will not be repeated here.

[0045] In order to effectively filter Byzantine node information, the driver block and the online car-hailing block can be added to the upper and lower alliance chains (that is, the two-layer blockchain network) respectively and then broadcast to the entire network.

[0046] After generating the driver block and the online car-hailing block, the driver block can be further added to the driver chain of the pre-established two-layer blockchain network, and the online car-hailing block can be added to the online car-hailing chain of the pre-established two-layer blockchain network. The specific operations are as follows:

[0047] (1) For the driver block:

[0048] First, the driver block is decrypted by the first public key, and the decrypted driver block is added to the driver chain of the pre-established two-layer blockchain network. For example, in one embodiment, each node on the driver chain (that is, each driver block on the driver chain) can be applied with the public key PK d Decryption verification M J ==M d , where M j =InverseECC(PK d , S d ), if it passes the verification, it will be added to the corresponding alliance chain, and after the chain is added, the joining information of the driver block will be sent to all blocks in the pre-established two-layer blockchain network through the first central node of the driver chain, that is, it will be broadcast to the whole network through the central node of the driver chain.

[0049] (2) For the online car-hailing block:

[0050] The online car-hailing block is decrypted by the second public key, and the decrypted online car-hailing block is added to the online car-hailing chain of the pre-established two-layer blockchain network based on the second timestamp, and the joining information of the online car-hailing block is sent to all blocks in the pre-established two-layer blockchain network through the second central node of the online car-hailing chain. The specific execution steps can be referred to the decryption, chaining and broadcasting operations for the driver block, which will not be repeated here.

[0051] In one embodiment, the relationship between the driver chain and the online car-hailing chain of the pre-established two-layer blockchain network is verified based on a preset consensus algorithm, and after both the driver chain and the online car-hailing chain are successfully verified, the matching result is determined. In this embodiment, since the blockchain network used is a two-layer blockchain network built based on this solution, the consensus algorithm adopts a PBFT consensus mechanism based on nested verification. The PBFT consensus mechanism based on nested verification can be seen in the following steps 1 to 6:

[0052] Step 1: Obtain the consensus request sent by the client and send it to the first central node and the second central node. The client (that is, the user terminal mentioned above) sends a request to the central nodes (the first central node and the second central node) of the two-layer blockchain network.

[0053] Step 2: Send the consensus request to all driver blocks of the driver chain through the first central node, and at the same time send the consensus request to all online car-hailing blocks of the online car-hailing chain through the second central node, so that all nodes of the driver chain and all nodes of the online car-hailing chain execute the preset consensus algorithm; wherein the preset consensus algorithm includes the preset nested verification PBFT consensus algorithm. For example, the double-layer master node broadcasts the request to other nodes at the same time, and the nodes execute the three-stage consensus process of the PBFT algorithm.

[0054] Step 3: After both nodes in the two layers have completed the three-stage consensus process of the PBFT algorithm, they return a message to the above client.

[0055] Step 4: After each node of the driver chain and each node of the online car-hailing chain have fed back the consensus result to the user terminal, the matching result is determined. In one embodiment, the client can also indicate that the consensus has been completed after receiving the same message from as many nodes as possible in the double layer. That is, after each node of the driver chain and the online car-hailing chain of the double-layer blockchain network returns a message, the consensus is completed.

[0056] Step 5: If the client only receives one layer (one layer of the driver chain or the online car-hailing chain) of the same message from as many nodes as possible, it means that the consensus has not been completed correctly. The consensus has not been completed correctly, which means that the correspondence between the online car-hailing chain and the driver chain has not been established. At this time, the View Change event needs to be enforced. For example, if the driver chain has completed the consensus but the online car-hailing chain has not completed the consensus, the driver chain needs to broadcast again and remove the previously added nodes so that the driver chain and the online car-hailing chain can correspond.

[0057] Step 6, after the two-layer consensus is reached, an internal call is made to query and verify the update of the online car-hailing link corresponding to the driver block, and the driver link corresponding to the online car-hailing block. If the correspondence is incorrect, a correction broadcast is made to update it to the correct state. For example, when the driver changes the vehicle, the vehicle link in the corresponding driver block changes, and the driver link in the previous corresponding online car-hailing block must also be changed accordingly and broadcast to the entire network. In one embodiment, when the vehicle information corresponding to the driver changes, the two parties can re-reach a consensus through the accounting method of both parties. When the consensus information can be completed, it means that the information has been successfully updated after the driver changed the vehicle.

[0058] For ease of understanding, the present invention also provides a specific method for verifying the security of online car-hailing information. Figure 3 A structural diagram of a verification system for the information security of an online car-hailing service is shown, which shows the specific structure of a two-layer blockchain network.

[0059] Create a registration dataset S iIncluding name, gender, age, ID number, household registration, driver's license number, driving experience, vehicle model, years of use, license plate number, whether it is an electric car, color and other information. Further, the legitimacy of the identity and driver's license information is verified through information sharing at the traffic control office, as well as previous traffic violation records. Vector E x , where x refers to the number of different violation types and the vector value refers to the corresponding degree / number of violations.

[0060] Generate a driving full node D (that is, generate the driver block mentioned above), generate a vehicle full node C (that is, generate the online car-hailing block mentioned above), and the specific implementation plan can be found in the above embodiment, which will not be repeated here.

[0061] When updating the online car-hailing records, that is, when the driver is punished by suspension of business, the corresponding disposal measures record is updated and the corresponding driver link is deleted. When changing the driver, the same driver ID change operation can be performed.

[0062] When updating the driver's credit record, the driver's credit score is updated through the traffic police's illegal incidents / user complaint incident information. Among them, Re n is the y-dimensional user complaint vector, b n is the corresponding user complaint weight parameter, and Incentive is the reward points for no violation during the period. When the points are lower than a certain level, the business will be suspended / stopped, and the corresponding available vehicle link (i.e. link) will be deleted.

[0063] In addition, through Figure 3 The information sharing of the light node traffic control station shown in can verify the legitimacy of the identity and driver’s license information, as well as the previous traffic violation record vector E x , where x refers to the number of different violation types and the vector value refers to the corresponding degree / number of violations.
