Logistics information traceability can improve logistics efficiency, reduce logistics risks, and enhance user trust.
[0003] Currently, traditional logistics information traceability mostly uses centralized databases to store logistics information and traceability is based on the logistics information stored in the database. However, such a solution makes the data vulnerable to attacks and tampering, resulting in poor credibility of logistics information and failing to meet the high requirements of modern logistics for information traceability.
[0004] Therefore, how to provide an effective solution to improve the credibility of logistics information traceability has become an urgent problem to be solved in existing technologies. Summary of the Invention

The local data index contains multiple data indexes of encrypted logistics orders. The data indexes of encrypted logistics orders record the order information of the corresponding encrypted logistics order and the storage address of multiple encrypted sub-data of the order content corresponding to the encrypted logistics order in the blockchain. Based on the target storage address, at least K encrypted sub-data items are retrieved from the blockchain, where K is a positive integer greater than 2; The first encrypted data is obtained by combining the at least K encrypted sub-data using the Lagrange interpolation method.

The process of splitting the original encrypted data into multiple original encrypted sub-data and storing them in the blockchain using the Shamir secret sharing scheme includes: After splitting the original encrypted data into multiple original encrypted sub-data using the Shamir secret sharing scheme, the multiple original encrypted sub-data and the first hash root corresponding to the order information of the completed logistics order are stored together in the blockchain.
[0009] In one possible design, retrieving at least K encrypted sub-data from the blockchain based on the target storage address includes: Based on the target storage address, retrieve the first hash root corresponding to the at least K encrypted sub-data and the order information of the logistics order to be traced from the blockchain; After decrypting the first encrypted data to obtain the order content of the logistics order to be traced, the method further includes: The order information of the logistics orders to be traced is hashed to obtain multiple second hash values; The multiple second hash values are used as leaf nodes, and the hash values of adjacent nodes are concatenated and hashed to obtain the second hash root corresponding to the order information of the logistics order to be traced.

The hash values of the multiple leaf nodes are combined in pairs to calculate the hash value, resulting in multiple new hash values. Multiple new hash values are recombined in pairs and the hash value is calculated again until only one hash value remains. The latest hash value is then used as the first hash root corresponding to the order information of the completed logistics order.
[0011] In one possible design, the at least K encrypted sub-data are combined according to the following formula to obtain the first encrypted data:
[0012] in, and These represent the i-th and j-th encrypted sub-data in at least K encrypted sub-data sets, respectively.
[0013] In one possible design, the order information for a traceable logistics order includes the order number, order name, and / or order time.

[0024] To improve the credibility of logistics information traceability, this application provides a blockchain-based logistics information traceability method, system, electronic device, and product. This blockchain-based logistics information traceability method, system, electronic device, and product can improve the credibility of logistics order traceability and meet the high requirements of modern logistics for information traceability.
[0025] The blockchain-based logistics information traceability method provided in this application can be applied to the backend terminal or server for logistics information traceability. It is understood that the described execution entity does not constitute a limitation on the embodiments of this application.
[0026] The following will provide a detailed description of the blockchain-based logistics information traceability method provided in the embodiments of this application.
[0027] like Figure 1 The diagram shown is a flowchart of a blockchain-based logistics information traceability method provided in the first aspect of the embodiments of this application. The blockchain-based logistics information traceability method may include, but is not limited to, the following steps S101-S105.
[0028] Step S101. Receive the logistics information traceability request initiated by the user.
[0029] The logistics information traceability request includes the order information of the logistics order to be traced. The order information of the logistics order to be traced may include, but is not limited to, the order number, order name, contact information, contact address and / or order time of the logistics order.
[0030] Step S102. Based on the order information of the logistics order to be traced, find the target storage address corresponding to the order information of the logistics order to be traced from the local data index.
[0031] The local data index library contains multiple data indexes of encrypted logistics orders. Each data index of encrypted logistics orders records the order information of the corresponding encrypted logistics order and the storage address of multiple encrypted sub-data of the corresponding order content in the blockchain.
[0032] In one or more embodiments, a data index can be built based on completed logistics orders and added to a local data index library. Specifically, the completed logistics orders can first be encrypted to obtain raw encrypted data. Then, the raw encrypted data is split into multiple raw encrypted sub-data using the Shamir secret sharing scheme and stored in the blockchain. Finally, the order information of the completed logistics orders is associated with the multiple raw encrypted sub-data to form a data index, and the formed data index is added to the local data index library.
[0033] In one or more embodiments, to facilitate the verification of logistics orders, the order information of completed logistics orders can be hashed to obtain multiple first hash values. These multiple first hash values are then used as leaf nodes, and the hash values of adjacent nodes are recursively concatenated and hashed to obtain the first hash root corresponding to the order information of the completed logistics order. When storing the original encrypted data into multiple original encrypted sub-data in the blockchain using the Shamir secret sharing scheme, the original encrypted data can be split into multiple original encrypted sub-data using the Shamir secret sharing scheme, and then the split multiple original encrypted sub-data and the first hash root corresponding to the order information of the completed logistics order can be stored together in the blockchain. By storing the first hash root corresponding to the order information in the blockchain, the stored first hash root can be conveniently used to verify the logistics order to be traced in subsequent logistics information tracing.
[0034] When using the multiple first hash values as leaf nodes and recursively concatenating the hash values of adjacent nodes to perform hash calculations to obtain the first hash root corresponding to the order information of the completed logistics order, the process can begin by using the multiple first hash values as leaf nodes. The hash values of the multiple leaf nodes are then combined in pairs to calculate the hash value, resulting in multiple new hash values. These new hash values are then combined in pairs again to calculate the hash value, and this process is repeated until only one hash value remains. This latest hash value is then used as the first hash root corresponding to the order information of the completed logistics order.
[0035] Understandably, in the process of combining hash values, if the number of hash values is odd, the last hash value can be directly used as the new hash value. For example, if the order information of a completed logistics order is hashed to obtain multiple first hash values, namely H11, H12, H13, H14, and H15, then when generating the first hash root corresponding to the logistics order, the first hash H11 and H12 can be concatenated and hashed to obtain the new hash value H21. The first hash H13 and H14 can be concatenated and hashed to obtain the new hash value H22. The remaining single first hash H15 can be used as the new hash value H23. Then, the hash values H21 and H22 can be concatenated and hashed to obtain the new hash value H31. The remaining single hash value H23 can be used as the new hash value H32. Finally, the hash values H31 and H32 can be concatenated and hashed to obtain the new hash value H41, and hash value H41 can be used as the first hash root corresponding to the order information of the completed logistics order.
[0036] Step S103. Find at least K encrypted sub-data from the blockchain based on the target storage address, where K is a positive integer greater than 2.
[0037] In one or more embodiments, after finding at least K encrypted sub-data from the blockchain, the first hash root corresponding to the at least K encrypted sub-data and the order information of the logistics order to be traced can be found from the blockchain based on the target storage address.
[0038] Step S104. Combine at least K encrypted sub-data using Lagrange interpolation to obtain the first encrypted data.
[0039] In one or more embodiments, the at least K encrypted sub-data can be combined according to the following formula to obtain the first encrypted data:
[0040] in, and These represent the i-th and j-th encrypted sub-data in at least K encrypted sub-data sets, respectively.
[0041] Step S105. Decrypt the first encrypted data to obtain the order content of the logistics order to be traced.
[0042] When decrypting the first encrypted data, it can be done using the key stored locally.
[0043] In one or more embodiments, after decrypting the first encrypted data to obtain the order content of the logistics order to be traced, the logistics order to be traced can also be verified.
[0044] Specifically, the order information of the logistics order to be traced can first be hashed to obtain multiple second hash values. Then, these multiple second hash values are used as leaf nodes, and the hash values of adjacent nodes are recursively concatenated and hashed to obtain the second hash root corresponding to the order information of the logistics order to be traced. Finally, it is verified whether the first hash root corresponding to the order information of the logistics order to be traced is consistent with the second hash root corresponding to the order information of the logistics order to be traced. If they are consistent, it indicates that the order content of the logistics order to be traced has not been tampered with; if they are inconsistent, it indicates that the order content of the logistics order to be traced may have been tampered with.
[0045] The present invention provides a blockchain-based logistics information traceability method, which involves receiving a logistics information traceability request initiated by a user, the request including order information of the logistics order to be traced; finding the target storage address corresponding to the order information of the logistics order to be traced from a local data index; then finding at least K encrypted sub-data in the blockchain based on the target storage address, wherein the local data index records multiple data indexes of encrypted stored logistics orders, and the data indexes of the encrypted stored logistics orders record the order information of the corresponding encrypted stored logistics orders and the storage addresses of multiple encrypted sub-data of the corresponding order content in the blockchain; combining the at least K encrypted sub-data using Lagrange interpolation to obtain first encrypted data; and finally decrypting the first encrypted data to obtain the order content of the logistics order to be traced. In this way, by encrypting and splitting the order content into multiple encrypted sub-data stores, and combining the anti-tampering function of blockchain, the security of the data can be further improved, preventing the logistics order content from being attacked and tampered with, improving the credibility of logistics order traceability, meeting the high requirements of modern logistics for information traceability, and facilitating practical application and promotion.
