Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of the said features.

The following description is provided to enable any person skilled in the art to implement and use the present invention. In the following description, details are set forth for purposes of explanation. It should be understood that those of ordinary skill in the art can recognize that the present invention can be implemented without the use of these specific details. In other instances, well-known structures and processes are not described in detail to avoid obscuring the description of the present invention with unnecessary details. Therefore, the present invention is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed herein.

[0055] Refer to Figure 1 , Figure 1 is a flowchart of the blockchain-based intelligent travel data management method provided by an embodiment of the present invention. Refer to Figure 1 The blockchain-based intelligent travel data management method provided by an embodiment of the present invention, which is applied to an upload node, may include steps 10 to 50:

[0056] Step 10, obtain the travel service data uploaded by the target user and the access permission of the travel service data.

[0057] Among them, the travel service data in this embodiment includes vehicle trip data, payment record data, and usage data. Among them, the vehicle trip data such as the starting point and ending point, trip distance, trip time, route information, etc., the payment record data such as the payment amount, payment time, payment method, account information, etc., and the usage data such as the usage frequency, usage period, service evaluation, etc. The access permission refers to which users or which platforms can access the travel service data.

[0058] Therefore, the upload node can obtain the travel service data uploaded by the target user and determine which users or platforms can access the travel service data, and obtain the access permission of the travel service data.

[0059] Step 20, upload the travel service data and its corresponding data digest to the travel data management system to receive the data address returned by the travel data management system.

[0060] Optionally, the data digest is obtained by processing the travel service data based on a data digest algorithm. Specifically, the uploading node can process the travel service data based on a data digest algorithm (such as the MD5 algorithm) to obtain the data digest of the travel service data, and then upload the travel service data and the data digest to the travel data management system. After uploading, it can receive the data address returned by the travel data management system, and this data address can be used to extract the travel service data and the data digest from the travel data management system.

[0061] It can be understood that the data digest can be used to verify and check the travel service data (data in plaintext) during the data sharing process to ensure the authenticity of the data.

[0062] Step 30: Aggregate the travel service data, the data digest, and the data address to obtain the first target data of the travel service data.

[0063] Optionally, the uploading node aggregates the travel service data, the data digest, and the data address to obtain the first target data of the travel service data, specifically as follows: The uploading node obtains the data digest and data address corresponding to the vehicle trip data, the data digest and data address corresponding to the payment record data, and the data digest and data address corresponding to the usage data. Further, the uploading node performs data aggregation processing on each data and its corresponding data digest with the data address of each data as a pointer. Therefore, with the data address of the vehicle trip data as a pointer, the vehicle trip data and its corresponding data digest are aggregated, with the data address of the payment record data as a pointer, the payment record data and its corresponding data digest are aggregated, and with the data address of the usage data as a pointer, the usage data and its corresponding data digest are aggregated to obtain the first target data of the travel service data.

[0064] In an embodiment, the data digest of the vehicle trip data A is TA, and the data address is PA. Therefore, the aggregated data of the vehicle trip data A is PA->[A:TA]. The data digest of the payment record data B is TB, and the data address is PB. Therefore, the aggregated data of the payment record data B is PB->[B:TB]. The data digest of the usage data C is TC, and the data address is PC. Therefore, the aggregated data of the usage data C is PC->[C:TC]. The finally obtained first target data of the travel service data is {PA->[A:TA], PB->[B:TB], PC->[C:TC]}.

[0065] Step 40: Encrypt the first target data to obtain the second target data of the travel service data and the signature data.

[0066] Optionally, the uploading node encrypts the first target data to obtain the second target data and signature data of the travel service data, specifically:

[0067] The uploading node obtains the hash value of the target blockchain node and the hash function Hash() of the target blockchain node based on the hash value, so as to obtain the hash function of the target blockchain node. At the same time, the uploading node obtains the private key and public key of the target blockchain node, where the private key includes a symmetric private key and an asymmetric private key, and the public key includes a symmetric public key and an asymmetric public key.

[0068] Further, the uploading node processes the first target data through the hash function to obtain a hash value K. Further, the uploading node encrypts the hash value through the symmetric private key M1 and the symmetric public key Q1 to obtain the signature data. Therefore, the signature data Sign can be expressed as .

[0069] Further, the uploading node encrypts the first target data Data through the asymmetric private key M2 and the asymmetric public key to obtain the second target data. Therefore, the second target data BData = .

[0070] Step 50: Package the second target data and the access right with the signature data, and send the packaged travel service data to the target blockchain node for storage.

[0071] Optionally, the uploading node packages the second target data and the access right with the signature data, and sends the packaged travel service data to the target blockchain node for storage, specifically:

[0072] The uploading node obtains the data type of the travel service data, where the data type includes a shared type, a privacy type, and a sensitive type, and the encrypted data formats of each data type are different.

[0073] Therefore, the uploading node determines the encryption position of the signature data according to the data type.

[0074] Further, if the data type is a shared type, the uploading node determines that the encryption location is the common location of the second target data and the access right, that is, both the second target data and the access right are encrypted. In this case, according to the signature data and its corresponding encryption location, the second target data and the access right are packaged to obtain the packaged travel service data, specifically: the signature data is used at the common location to package the second target data and the access right to obtain the packaged travel service data. The packaged travel service data is: FData = {BData, Access}Sign, where FData is the packaged travel service data, BData is the second target data, Access is the access right, and Sign is the signature data.

[0075] Further, if the data type is a privacy type, the uploading node determines that the encryption location is the first private location of the access right, that is, only the access right is encrypted. In this case, according to the signature data and its corresponding encryption location, the second target data and the access right are packaged to obtain the packaged travel service data, specifically: the signature data is used at the first private location to package the second target data and the access right to obtain the packaged travel service data. The packaged travel service data is: FData = {BData, (Access)Sign}, where FData is the packaged travel service data, BData is the second target data, Access is the access right, and Sign is the signature data.

[0076] Further, if the data type is a sensitive type, the uploading node determines that the encryption location is the second private location of the second target data, that is, only the second target data is encrypted. In this case, according to the signature data and its corresponding encryption location, the second target data and the access right are packaged to obtain the packaged travel service data, specifically: the signature data is used at the second private location to package the second target data and the access right to obtain the packaged travel service data. The packaged travel service data is: FData = {(BData)Sign, Access}, where FData is the packaged travel service data, BData is the second target data, Access is the access right, and Sign is the signature data.

[0077] In the embodiment of the present invention, the first target data of the travel service data is generated through data aggregation processing, and then the first target data of the travel service data is encrypted, so that the integrity and confidentiality of the encrypted second target data are higher. The second target data and the access right are signed through the signature data of the travel service data, and then the signed travel service data is stored in the target blockchain node, so that the intelligent travel data cannot be modified artificially, and the anti-tampering property of the intelligent travel data is realized.

[0078] The following describes the blockchain-based intelligent travel data management system provided by the present invention.
