Detailed Implementation

[0016] The exemplary embodiments of this disclosure are described below with reference to the accompanying drawings, including various details of the embodiments to aid understanding, and should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of this disclosure. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0017] Example 1

[0018] The information security interaction method based on consensus protocol provided in this disclosure is hereby referred to. Figure 1 As explained, the method includes:

[0019] Define the participants in information interaction, wherein the participants include a service information center, a user terminal, and a verification terminal;

[0020] Specifically, multiple participants involved in the information exchange are defined, including a service information center, user terminals, and verification terminals. The service information center is the server network for information exchange, the user terminals are the vehicle users involved in the transaction, and the verification terminals are multiple clients used to verify vehicle maintenance information and assess vehicle health. For example, verification terminals may include vehicle trading shops and vehicle trading intermediaries.

[0021] According to the data request instruction, user terminal participation information interaction is carried out, the first sender is determined, and the service information center and the verification terminal among the participants are authenticated. If the authentication operator is obtained, the identity authentication is completed according to the interaction key received by the first sender.

[0022] Specifically, a data request instruction is obtained for vehicle transactions. Based on the received data request instruction, user-side information interaction is initiated, and the user-side interactive information is sent. The user-side is then identified as the first sender. The service information center and verification terminals among the participants are authenticated, and the ownership relationship between the first sender's vehicle information and the user's rights is verified. When multiple verification terminals successfully authenticate the first sender, they obtain an authentication operator and complete the authentication process by receiving the interaction key from the first sender. The interaction key is used to encrypt and decrypt the interactive information.

[0023] Based on the first interaction information from the first sender, the interaction information is encrypted using the interaction key, and the encrypted first interaction information is distributed to the service information center and the verification terminal to determine multiple verification parties.

[0024] Specifically, the first interaction information from the first sender is encrypted using an interaction key to obtain encrypted first interaction information. This encrypted first interaction information is then distributed to the service information center and the verification terminal for information verification, thereby confirming that both the service information center and the verification terminal are verifiers, thus obtaining multiple verifiers.

[0025] A consensus protocol is established through a blockchain network architecture to determine the protocol objectives, wherein each of the aforementioned verifiers corresponds to a blockchain;

[0026] Specifically, when multiple verifiers receive the first interaction information, each verifier is identified as a separate blockchain. These blockchains are then interconnected to obtain the blockchain network architecture. Based on this network architecture, a consensus protocol is established between the blockchains, and the protocol objective is determined. The objective is to verify the first interaction information and obtain the verification result.

[0027] Based on the encrypted first interaction information received by multiple verification parties, and based on the protocol objective, the integrity of the first interaction information is calculated through the consensus protocol to obtain a verification operator. If the first data block consensus threshold is met, the first receiver is determined based on the participation of the first sender in the conversion, and the authenticity is calculated through the first receiver to obtain the first consensus verification information.

[0028] Specifically, based on the encrypted first interaction information received by multiple verifiers, and with the protocol objective as the execution goal, the integrity of the first interaction information is calculated through the consensus protocol to obtain a verification operator. When the verification operator is deemed valid, the integrity calculation result of the first interaction information satisfies the first data block consensus threshold. Based on the participation of the first sender, the first sender is transformed into the first receiver, thereby determining the verification result of the first receiver's acquisition of the first interaction information. The first receiver then performs an authenticity calculation to obtain the first consensus verification information.

[0029] The first consensus verification information is decrypted based on the interaction key, thereby completing the data interaction among the participants.

[0030] Specifically, the first consensus verification information is decrypted based on the interaction key, thereby completing the data interaction among the participating parties: the user terminal, the service information center, and the verification terminal.

[0031] This embodiment addresses the technical problem of low data transparency in existing technologies, where traditional vehicle repair records may be falsified or inconsistent. It achieves the goal of storing certified repair records on the blockchain, thus creating tamper-proof repair records. By accessing the data on the blockchain to monitor and evaluate the repair records, the technical effect of improving the transparency and credibility of vehicle repairs and protecting user rights is achieved.

[0032] The method provided in this disclosure also includes:

[0033] Extract the vehicle maintenance records from the first sender, and perform time-series processing on the vehicle maintenance records according to time-series characteristics to obtain vehicle maintenance time-series records;

[0034] Based on the vehicle maintenance time sequence record, obtain the first time sequence and the second time sequence of vehicle maintenance time sequence records, verify the impact configuration, and obtain the verification reference of the first interaction information.

[0035] Specifically, the vehicle maintenance records of the first sender are extracted, where the vehicle maintenance records are the vehicle maintenance data of the first sender within a historical period. Based on the time sequence characteristics, the vehicle maintenance records are processed to obtain the vehicle maintenance time sequence records.

[0036] Furthermore, the first time series is the last time of the time period in the time series feature, and the second time series is the time node of the time period excluding the first time series. Vehicle maintenance time series records for both the first and second time series are obtained. The impact configurations of the first and second time series vehicle maintenance time series records are then verified. The first time series vehicle maintenance time series records have a greater impact on vehicle health; therefore, a higher impact value is assigned to the first time series vehicle maintenance time series records, and a lower impact value is assigned to the second time series records. The impact values ​​of the first and second time series records are then combined to obtain a verification reference for the first interaction information. This verification reference for the first interaction information can improve the accuracy of obtaining vehicle health certificates.

[0037] The method provided in this disclosure also includes:

[0038] By extracting the first interactive information, fault codes, repair measures and parts replacement information are extracted from the vehicle repair record, and the character length is calculated to obtain the first length, the second length and the third length.

[0039] The first interactive information is transmitted to the verification party, and the character length of the fault code, the maintenance measures, and the parts replacement information is verified according to the blockchain to obtain the first verification length, the second verification length, and the third verification length.

[0040] According to the protocol objective, the first verification length, the second verification length, and the third verification length are used to perform integrity verification on the first verification length, the second verification length, and the third verification length, respectively, to obtain the verification operator.

[0041] Specifically, by extracting the first interaction information outside the blockchain, fault codes, repair measures, and parts replacement information from the vehicle maintenance records in the first interaction information are obtained. Among them, information on the vehicle's health status is obtained through the fault codes, repair measures, and parts replacement information. The character length of the fault codes, repair measures, and parts replacement information is calculated respectively to obtain the first length, second length, and third length.

[0042] Furthermore, by transmitting the first interactive information to the verifier in the blockchain, the verifier performs verification, namely, verifying the character length of fault codes, maintenance measures, and parts replacement information through the blockchain, and obtaining the first verification length, the second verification length, and the third verification length.

[0043] Furthermore, based on the verification results of the first interaction information obtained from the protocol objective, integrity verification is performed on the first verification length against the first length, the second verification length against the second length, and the third verification length against the third length, respectively, to obtain the verification operator. Performing integrity verification separately can improve the verification accuracy of the first interaction information.

[0044] The method provided in this disclosure also includes:

[0045] The verification operator includes verification pass and verification fail;

[0046] The verification failure means that if the integrity verification result does not meet the consensus threshold of the first data block, the blockchain network architecture is obtained for data backup and recovery.

[0047] The verification is considered successful if the integrity verification result meets the first data block consensus threshold. Then, the authenticity of the first interaction information is calculated based on the verification reference to generate the first consensus verification information.

[0048] Specifically, the verification operator includes verification pass and verification fail. Verification fail occurs when the integrity verification result does not meet the first data consensus threshold. This means that the first verification length, second verification length, and third verification length are inconsistent with the first, second, and third verification lengths, which may indicate missing data transmissions. Therefore, the blockchain network architecture is obtained for data backup and recovery.

[0049] Furthermore, if the integrity verification result meets the first data block consensus threshold, it means that the first verification length, second verification length, and third verification length are consistent with the verification lengths of the first, second, and third lengths. Then, the first interaction information is extracted, weighted according to the verification reference, and its authenticity is calculated to generate the first consensus verification information. The acquisition of the verification operator can improve the accuracy of acquiring the first consensus verification information.

[0050] The method provided in this disclosure also includes:

[0051] Based on the verification party's vote on the authenticity of the first interactive information, multiple authentic verification vote results are obtained;

[0052] Based on the credibility of the verifier, the multiple real verification voting results are weighted to obtain the first consensus verification information.

[0053] Specifically, the verification party votes on the authenticity of the first interactive information, that is, it verifies the authenticity of vehicle maintenance data and vehicle user information in the first interactive information. If the verification is qualified, it votes on authenticity and obtains the true result; if the verification is unqualified, it votes on authenticity and obtains the false result.

[0054] Furthermore, based on the subjective initiative of the validators in information exchange, the credibility of multiple validators is obtained. The credibility impact of the voting results is obtained by weighting the multiple genuine validator voting results with the credibility of the voting validators, and this credibility impact is further weighted to obtain the first consensus verification information. Obtaining genuine voting results can improve the authenticity of the obtained first consensus interaction information.

[0055] The method provided in this disclosure also includes:

[0056] Based on the authenticity voting results in the first consensus verification information, blockchain extraction is performed to obtain the verifier;

[0057] The first consensus verification information is updated and stored according to the verification party, and the first consensus verification information is updated and obtained.

[0058] Specifically, based on the authenticity voting results in the first consensus verification information, the blockchain that conducted the voting is obtained, i.e., the voting verification party that conducted the authenticity voting results is obtained. Further, based on the verification party that conducted the voting, an update verification is performed over time to obtain verification results for multiple time-series features. These multiple verification results are then updated and stored to obtain the first consensus verification information. Updating and verifying the first consensus verification information can improve the accuracy of obtaining it.

[0059] The method provided in this disclosure also includes:

[0060] The first consensus verification information in the blockchain is tracked and monitored. When the first monitoring update information is obtained, the authenticity of the first consensus verification information is corrected. If the correction is not qualified, the integrity calculation is performed until the correction is qualified.

[0061] If the correction is successful, it is added to the first consensus verification information.

[0062] Specifically, the first consensus verification information in the blockchain is tracked and monitored, and the sending and receiving blocks of the first consensus verification information are obtained, marking the completion of the sending and receiving of the first consensus verification information. When the sending and receiving of the first consensus verification information is confirmed, the authenticity can be checked by the current confirming verifier. If the correction fails, it indicates that the accuracy of the updated first consensus verification information is low, and an integrity calculation is performed until the first consensus verification information is obtained. If the correction passes, it indicates that the accuracy of the updated first consensus verification information is high, and the first consensus verification information is obtained. Obtaining the first monitoring update information can improve the accuracy of obtaining the first consensus verification information.

[0082] The module for obtaining real verification voting results is used to obtain multiple real verification voting results based on the verification party's vote on the authenticity of the first interaction information.
