A detailed description

In order to make the purpose, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments These are some embodiments of the present disclosure, but not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of this disclosure.

Figure 1 schematically shows a flow chart of a product information entry method provided by the present disclosure, which is applied to the information management end of the blockchain system. The method includes:

Step 101: In response to the information entry request sent by the target parallel chain node in the blockchain system, send an encryption key to the target parallel chain node.

It should be noted that the blockchain system is a functional system built based on the blockchain, which can provide functions such as entry, storage, and traceability query of product information. The blockchain system includes the blockchain and information management end.

Referring to Figure 2, the blockchain can be a main chain constructed in the form of a consortium chain. The main chain is a formally launched and independent blockchain network. It is a trusted blockchain network recognized by the blockchain community. Its transactions The information is recognized by all member nodes, and valid blocks will be appended to the blockchain on the main chain's block ledger after consensus on the blockchain network. In this disclosure, each node in the main chain can include a sub-chain in the form of a parallel chain node. Each parallel chain node has an independent smart contract, so that consensus can be achieved within the parallel chain node without involving nodes other than other parallel chain nodes. mechanism, so that the parachain node does not need to request all nodes in the main chain to reach a consensus every time it deposits and transmits data, but only needs to reach a consensus within the parachain node.

The information management terminal is an application server connected to the blockchain. It is mainly used to provide functions such as information entry, key management, and information traceability query to each node in the blockchain. It can also be set up in the form of a parallel chain. In the blockchain, or when accessing the blockchain in the form of an external server, you only need to write in the smart contract of the blockchain to allow the information management terminal to enter information and The relevant mechanism for information traceability query is enough. The specific settings can be set according to actual needs and are not limited here.

In the embodiment of the present disclosure, the information management end can actively or passively obtain encrypted product information from the parallel chain nodes in the blockchain system. The product information refers to the location information, transaction information, and status of the products provided by the parallel chain nodes. information and other product-related information. However, considering the security of product information, the parallel chain node needs to encrypt the product information when sending it. The encryption method can be to request the encryption key from the information management end to ensure that the subsequent information management end can encrypt the product information. For unified management, it can be understood that if the encryption key for encrypted information is not provided by the information management end, the information management end cannot decrypt the product information, and it cannot provide the decrypted product information to the parallel chain node.

In practical applications, the owners of parallel chain nodes can be various companies that produce or sell various products or companies with different brands of the same product. Since companies usually only focus on the product information of the products they provide, through parallel chain Accessing the blockchain system in the form of chain nodes eliminates the need for companies to obtain the approval of parallel chain nodes associated with unrelated companies, and their product information does not need to be synchronized to the parallel chain nodes of other unrelated companies, ensuring the integrity of product information. safety. Specifically, the enterprise can upload the product information of the products it provides to its corresponding parallel chain node to trigger the parallel chain node to send an information entry request to the information management terminal to enter the product information into the blockchain system through the information management terminal.

Step 102: Receive the encrypted product information encrypted by the target parallel chain node using the encryption key.

In the embodiment of the present disclosure, the parallel chain node can set the interface of the SDK for information encryption in its device to encrypt the product information into encrypted product information through the encryption key provided by the information management end, and send the encrypted product information to Information management side.

Step 103: When the authentication node in the blockchain system and the associated parallel chain node of the encrypted product information pass the identity verification of the target parallel chain node, upload the encrypted product information to the associated parallel chain node. chain node.

It should be noted that the certification node is a node in the blockchain system used to issue certification qualifications to other nodes. The certification node can also participate in the consensus mechanism in the blockchain system. The associated parachain nodes of the encrypted product information at least include the target parachain node for uploading the encrypted product information, and may also include other parachain nodes associated with the encrypted product information. The association between the encrypted product information and the parachain nodes can be It is preset in the smart contract in the main chain, so that when information is entered, the associated parachain nodes associated with product information are automatically selected from multiple parachain nodes.

In this disclosed embodiment, the information management end sends the encrypted product information to the alliance main chain in the blockchain, triggering the authentication node in the main chain and the associated parallel chain node related to the encrypted product information to target the target parachain node. During the identity authentication process, the remaining parachain nodes that have nothing to do with the encrypted product information will not participate in the authentication. Therefore, when the associated parachain nodes and the certification nodes reach a consensus, that is, when the identity authentication of the target parachain nodes has passed, the encrypted product information will be encrypted in blocks. The driving is synchronized to the associated parachain nodes, including the target parachain node. Furthermore, if the information management terminal is connected to the blockchain system in the form of a parallel chain node, the encrypted product information will also be synchronized to the information management terminal. If the information management terminal is not connected to the blockchain system in the form of a parallel chain node, a smart contract can be set up so that the parallel chain node automatically synchronizes the encrypted product information to the information management terminal after synchronizing the encrypted product information.

This disclosed embodiment sets up a system management end in a blockchain system constructed in the form of a parallel chain, so that when the parallel chain node enters product information, it provides an encryption key to encrypt the product information and then only needs to authenticate it after entering it into the blockchain. Once the node reaches a consensus with the parachain node associated with the entered product information, the encrypted product information can be entered into the parachain node associated with the product information, thus avoiding the risk of plain text product information being obtained by other unrelated parties and improving the efficiency of uploading product information to the chain. security.

Optionally, referring to Figure 3, the method further includes:

Step 201: Receive a product information query request sent by the target parallel chain node, where the product information query request at least includes: a product information identifier.

In the embodiment of the present disclosure, when the owner of the target parallel node needs to perform traceability query on product information, he or she can obtain the product information for which he or she has the query authority by logging in to the information management terminal.

Step 202: When the target parallel chain node has the query authority corresponding to the product information identifier, obtain the encrypted product information corresponding to the product information identifier.

In this disclosed embodiment, the information management end will determine whether it can query the product information corresponding to the product information identifier based on the query permission of the target parallel chain node. When it has the query permission, it can obtain the encrypted product by querying from the chain. information, or query encrypted product information from locally stored synchronized information.

Step 203: The product information obtained by decrypting the encrypted product information is sent to the target parallel chain node.

In this disclosed embodiment, since the encryption key for encrypting product information is provided by the information management end, the information management end also has a decryption key for decrypting the encrypted product information. The encryption key and the decryption key can be The same key in the form of symmetric encryption can also be the public key and private key in the form of asymmetric encryption. The details can be set according to actual needs and are not limited here. Specifically, the information management end decrypts the encrypted product information through the decryption key and then provides it to the target parallel chain node for the user to view.

This disclosure implements the encryption and decryption process of product information at the information management end, so that product information can only be traced and queried at the information management end, thereby improving the security of product information.

Optionally, the step 202 may include querying the encrypted product information corresponding to the product information identifier in the synchronization information synchronized by the associated parallel chain node to the information management terminal.

In the embodiment of the present disclosure, the information management end can set up a content service module inside it, so that by accessing the blockchain in the form of a content service module, the associated parallel chain node can synchronize the encrypted product information to the encrypted product information. Product information is synchronized to the information management terminal for subsequent traceability inquiries of product information.

Optionally, referring to Figure 4, after step 103, the method further includes:

Step 104: Obtain the authentication information sent by the authentication node in the blockchain system for the product information.

In the embodiment of the present disclosure, the certification information may be the qualification certification provided by the certification node for the product information, so that the parallel chain node can verify the qualification of the product.

Step 105: Upload the authentication information to the associated parallel chain node.

In this disclosed embodiment, the information management end will also upload the authentication information to the associated parallel node for query by the associated parallel node.

Through the third-party certification node audit, the company's parallel chain node can be certified for code issuance, and the data can be uploaded to the chain to verify the authority. The product issuance of a pass can accurately track the flow and usage of each share of the product based on the actual production situation to prevent cross-selling. Consumers can check it at any time by scanning the QR code. It is safe and trustworthy, and the pass can be checked; the finished product information is uploaded to the chain. One thing, one pass, enabling product life cycle tracking and traceability. According to the product circulation situation, the entire distribution system can be put on the chain to help enterprises achieve overall control of the distribution chain.

Optionally, the blockchain system can also provide digital points for e-commerce platforms: digital points are used to encourage consumer consumption, consumers share recommendations, etc.; product digitization, product coupons: used for pre-sales, bulk purchases, transfers, investment transfers etc.; product coupons expand new distribution channels, obtain full data from dealers to consumer terminals, and create a marketing big data platform.

Optionally, step 103 includes: when the authentication node in the blockchain system, the associated parachain node of the encrypted product information, and the supervisory node pass the identity verification of the target parachain node, The encrypted product information is uploaded to the associated parallel chain node.

In the embodiment of the present disclosure, the blockchain system may also include a supervision node. The supervision node is a node and smart contract responsible for managing and coordinating the blockchain. It is usually owned by the builder of the blockchain, while the certification node is an intermediary. As a third-party node between the supervision node and the parallel chain node, the introduction of this node is mainly due to the possible storage of interest relationships between the supervision node and the parallel chain node, or the supervision node only provides blockchain system support and cannot directly Products provided by parallel chain nodes provide valid certification qualifications. For example, in industries such as commercial wine, food, and electronic products, the providers of supervision nodes may be just service providers with low credibility for commodities. Therefore, commodity industry supervision agencies or units with higher credibility for commodities can be introduced. As a third-party responsible for the certification node, it provides qualification certification for the goods or materials provided by the parallel chain node.

Figure 5 schematically shows a flow chart of yet another method of entering product information provided by the present disclosure, which is applied to a parallel chain node in a blockchain system. The method includes:

Step 301: When product information is obtained, an information entry request for the product information is sent to the information management terminal in the blockchain system.

Step 302: Receive the encryption key sent by the information management terminal according to the information entry request.

Step 303: Use the encryption key to encrypt the product information to obtain encrypted product information.

Step 304: Send the encrypted product information to the information management terminal, so that the information management terminal enters the encrypted product information into the blockchain system through the entry method of the product information.

For the steps 301 to 304, reference may be made to the description of steps 101 to 103, which will not be described again here.

Optionally, the step 301 may include: obtaining the product information collected by the locator connected to the target parallel link node, where the locator is provided on the product, and the locator is used to search for the target parallel link node. The chain node uploads the product information of the product.

In the embodiment of the present disclosure, when the owner of the target parachain node does not have ready-made product information, data entry is required. The target parachain node can be entered by data collection from an Internet of Things terminal such as a locator installed on the product.

Optionally, obtaining product information may include: obtaining product information from an enterprise information system connected to the target parallel chain node.

In this disclosed embodiment, the owner of the target parallel chain node already has an ERP (Enterprise Resource Planning) system with complete product information. Data can be uploaded to the chain in batches and selectively by connecting to the standard SDK interface. No manual entry is required, reducing the burden.

Optionally, referring to Figure 6, the method further includes:

Step 401: In response to the received information query operation, send a login request to the information management terminal in the blockchain system.

Step 402: Receive the permission information sent by the information management terminal according to the login request.

Step 403: Display the product information identification corresponding to the permission information.

Step 404: In response to the selection operation of the target product information identifier among the product information identifiers, send a query request carrying the target product information identifier to the information management end.

Step 405: Receive product information corresponding to the target product information identifier sent by the information management terminal.

Steps 401 to 405 are similar to steps 201 to 203. The difference is that the target parachain node does not directly provide the product information identification to the information management terminal, but requests permission information by logging in to the information management terminal so that the permissions can be viewed. Product information identifiers within the range for users to select the target product information identifier to view.

Figure 7 schematically shows the structural diagram of a blockchain system provided by the present disclosure. The blockchain system includes: an alliance chain and an information management terminal 2. The alliance chain at least includes: a supervision node 11, a certification Node 12, parachain node 13;
