Detailed Description
Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that: the relative arrangement of the components and steps, the numerical expressions, and numerical values set forth in these embodiments do not limit the scope of the present disclosure unless specifically stated otherwise.
Meanwhile, it should be understood that the sizes of the respective portions shown in the drawings are not drawn in an actual proportional relationship for the convenience of description.
The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the disclosure, its application, or uses.
Techniques, methods, and apparatus known to those of ordinary skill in the relevant art may not be discussed in detail, but are intended to be part of the specification where appropriate.
In all examples shown and discussed herein, any particular value should be construed as merely illustrative, and not limiting. Thus, other examples of the exemplary embodiments may have different values.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.
As mentioned above, product traceability often involves multiple links, i.e., multiple parties uploading traceability information. For example, agricultural product traceability relates to a plurality of supply chain links such as a planting processing link, an agricultural product circulation link, a logistics distribution link and the like. The participants of different supply chain links come from different entities (e.g., enterprises, organizations, etc.).
Multiple traceability information of the same product originates from different parties. After the tracing information is uploaded to the block chain system by each participant through each block chain link point, each tracing information of the same product is stored in different blocks. Each block has a respective transaction identification (TX _ ID).
With such a key-value data storage structure, all tracing information of the same product is queried through transaction identification or block address, and interaction with subsystems of multiple hierarchies is required. This leads to technical problems of complicated tracing process, incomplete tracing result, and the like.
Therefore, in order to solve the above technical problem, it is necessary to punch through the fragmented trace-source data on the blockchain. The method and the system establish the mapping relation between the product identification and each related transaction identification, and store the mapping relation into the database for index query of complete traceability information. By inquiring the product identifier, the related block chain addresses are determined, and the complete traceability information is acquired or displayed from the blocks according to the address information.
Moreover, by utilizing the index query, more business logic operations can be carried out, such as business processing capabilities of data query authority control, data operation log management, data transaction and the like.
The technical solution of the present disclosure can be realized by the following embodiments.

For example, the generation participants of a certain agricultural product, such as a grower, a processor, a supplier, a logistics party, a seller, and the like, are all added to the blockchain system by the identity of the blockchain node. For example, a peer-to-peer network structure can be formed among the blockchain nodes, and a federation chain system is established on the basis of the peer-to-peer network structure.
In this way, each participant can upload traceability information through its own block link point.
In step 120, the transaction identifier of the block storing each tracing information is associated with the product identifier of the product.
In some embodiments, the association relationship between the transaction identifier of the block storing each tracing information and the product identifier of the product is stored in a tracing database outside the blockchain system.
In some embodiments, the transaction identifier (transaction address) may be transferred to a traceability database and mapped to an agricultural product traceability code (corresponding to the product identifier). For example, the mapping relationship of the agricultural product traceability code and the blockchain address of all traceability information related to the agricultural product traceability code can be stored under the chain.

In step 210, the corresponding tracing information is encrypted according to the first key generated by each block link point and then stored in the block.
In some embodiments, a symmetric key K is generated by the uplink node before uplink of the traceback information1. Uplink node utilization K1And a corresponding symmetric key algorithm E (X), encrypting the traceable plaintext P of the uplink to generate a ciphertext C1＝E(K1P). For example, the plaintext may be as shown in table 1.
In step 220, each tracing information and its corresponding first key are encrypted according to the second key uploaded by the user.
In some embodiments, the user is determined to have the right to obtain the traceable plaintext PThereafter, the uplink node can utilize the public key K provided by the user2For ciphertext C1Key K of1Encrypting to obtain an encrypted secret key C2。

In some embodiments, C1、C2Transmitted to the user as ciphertext together. After receiving the ciphertext, the user decrypts C by using the private key of the user2Restore the symmetric key K1And then reuse the obtained K1Decrypting C according to a predetermined symmetric key algorithm1And obtaining the traceable plaintext P. For example, the traceable plaintext P may be presented to the consumer according to a preset template.
Fig. 3 illustrates a schematic diagram of some embodiments of a traceability method of the product of the present disclosure.
As shown in fig. 3, the blockchain system can receive the traceability data of each participant through the blockchain standard interface. For example, data such as planting, processing, production, warehousing and distribution, and sales information in the agricultural product supply chain are transmitted to corresponding blockchain nodes through TCP/IP (Transmission Control Protocol/Internet Protocol).
In some embodiments, data for each link is uplinked via a respective block link point and signed using the current node certificate. For example, encrypting the uplink data using symmetric encryption ensures the security of the uplink data and also guarantees the data query performance.
In some embodiments, the blockchain system may store the transaction identifier of the traceability data of each participant in the traceability database after binding with the corresponding product identifier.
For example, the transaction identification of the production tooling data may include a transaction identification of a production data address, an environmental data address, tooling data, and the like. The transaction identification of the food circulation data can comprise transaction identification of production place data, inter-data and batch data. The transaction identifier of the logistics distribution data can comprise transaction identifiers of warehouse data, transportation data and handover information.
In some embodiments, the blockchain system obtains a plurality of corresponding transaction identifiers from the tracing database according to the product identifiers queried by the user, and returns the tracing data corresponding to the transaction identifiers to the user.
In some embodiments, a user may perform a traceback data query to the blockchain system through a blockchain standard interface. For example, by using the data query authority configured in the source tracing database, when the user scans the code through the mobile terminal to perform source tracing, the authority can be verified at the same time.
After the permission verification is passed, the tracing database can return the encrypted tracing information to the user terminal by using an asymmetric encryption technology. And after the terminal is decrypted by the private key, the agricultural product tracing record can be checked. Other unauthorized nodes have no way to obtain the corresponding information.
