Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments, but not all embodiments, of the technical solutions of the present application. All other embodiments obtained by a person skilled in the art without any inventive step based on the embodiments described in the present application are within the scope of the protection of the present application.

The terms "system" and "network" in the embodiments of the present application may be used interchangeably. "at least one" means one or more, "a plurality" means two or more. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone, wherein A and B can be singular or plural. At least one of the following or similar expressions refer to any combination of these items, including any combination of singular or plural items. For example, at least one (one) of a, b, or c, may represent: a, b, c, a-b, a-c, b-c, or a-b-c, wherein a, b, c may be single or multiple.

Unless stated to the contrary, the embodiments of the present application refer to the ordinal numbers "first", "second", etc., for distinguishing between a plurality of objects, and do not limit the sequence, timing, priority, or importance of the plurality of objects. For example, the first node and the second node are only for distinguishing different nodes, and do not indicate the difference between the two nodes, priority, importance level, or the like.

Furthermore, the terms "comprising" and "having" in the description of the embodiments and claims of the present application and the accompanying drawings are not exclusive. For example, a process, method, system, article, or apparatus that comprises a list of steps or modules is not limited to only those steps or modules listed, but may include other steps or modules not listed.

Special commodities generally comprise civil explosive, highly toxic chemicals, fireworks and crackers, easily-manufactured gunnery articles, easily-manufactured and exploded dangerous chemicals and industrial electronic detonators. At present, the production, transaction, transportation and use of special commodities are mainly carried out by enterprises, and the whole process is supervised by a management unit.

At present, information on a specific commodity is independent between a producer, a purchaser, a storage and a user of the specific commodity. The management unit needs to monitor (manage) the life cycle of all specific articles (including production, transaction, transportation, storage, use and other links) and acquire the flow information of the special commodities. In general, an enterprise that is involved in a particular item needs to obtain a corresponding license certificate at the administrative entity. The purchaser of the special product needs to provide a purchase approval certificate in the management unit before purchasing the product. Before transporting the goods, the special goods transporter needs to provide a transportation license certificate in the management unit. Before some specific commodities are operated and used, records need to be put on record in a management unit. The complicated application and approval process and the off-line issuing of the paper documents increase the burden of management units and relevant practitioners of special commodities in the processes of information filling, document issuing and certificate authenticity identification. And the risk of forging the license certification of the special commodity or tampering the data is higher, so that the life cycle tracking difficulty of the special commodity is increased.

In view of this, embodiments of the present application provide a method, a system and a computer storage medium for commodity life cycle management, which can provide a license certification required in a commodity production and operation process by using a block chain technology, and reduce the risk of creating a license certification for a special commodity or tampering data, so that the life cycle of the special commodity is traceable and queriable.

Fig. 1 illustrates a product lifecycle management system according to an embodiment of the present application. The commodity life cycle management system provided by the embodiment of the application can comprise a block chain network. The blockchain network may include a plurality of nodes. The plurality of nodes may include a plurality of business nodes, a plurality of production nodes, a plurality of transportation nodes, a plurality of storage nodes, a plurality of usage nodes, and a plurality of management nodes.

In the embodiment of the present application, the "node" may be an electronic device or a server. A node may have one or more node types. The node types in the application can comprise production types, transportation types, operation types, storage types and use types. The business class may include a sales class and a purchase class, among others. For example, if the type of node A only includes a production class, then node A is a production node. Also for example, the types of node bs include a production class and a business class. The node B is both a production node and an administration node.

The production node may be a node used by a special commodity manufacturing enterprise. The business node may be a node used by a particular merchandising enterprise, such as a node used by a sales enterprise, or a node used by a purchasing enterprise. The transportation node may be a node used by a special commodity transportation enterprise. The storage node may be a node used by a special commodity storage enterprise. The use node may be a node used by a special commodity use enterprise, the use enterprise may be an enterprise or an organization that uses a special commodity job, or an enterprise or an organization that handles a special commodity. The production node can be a node used by a special commodity management enterprise, and the management enterprise can be a unit for monitoring the life cycle of the special commodity.

In some examples, an enterprise may have multiple types of roles. For example, an enterprise belongs to a production and management type enterprise, and after the enterprise produces dangerous goods, the enterprise itself undertakes storage work, so that the enterprise is both a production node and a storage node.

In one possible design, as shown in fig. 1, in the block chain network in the commodity production cycle management system provided in the embodiment of the present application, each production node, each business node, each transportation node, each storage node, each use node, and each management node are in the same alliance chain.

The alliance chain belongs to the category of private chains, and the privacy degrees of different alliance chains are different. Usually constructed by members of a group organization, belonging to a licensed blockchain network. The newly joined member needs to obtain the identity certificate and has access right to join the alliance chain. The alliance chain realizes partial decentralization, and partial core members agreed in advance carry out consensus work on transactions in the network. Other members may query the federation chain for records of transactions, but permission from the core member is required to verify the transaction or issue the transaction. In another possible design, as shown in fig. 2, the blockchain network in the commodity production cycle management system provided in this embodiment of the present application includes a plurality of federation chains, and each federation chain includes at least one audit node. Each federation chain also includes one or more of: production node, management node, transportation node, storage node, use node. Information interaction between any two alliance chains can be carried out through a super chain or a cross-chain technology. It should be noted that the number of federation chains in the blockchain network shown in fig. 2 is only used for illustration and is not a specific limitation on the number of federation chains. The number of nodes of each type in a federation chain is also used for illustration and is not intended as a specific limitation on the structure of the federation chain.

Optionally, for any alliance chain in the product production period management system, the joining node may join the alliance chain after obtaining the legal identity. The management node may generate a public key and a private key of the node according to the name, tax number, and node type of the enterprise or organization to which the node belongs. And issues a Certificate Authority (CA) for the node. In the commodity production cycle management system, the CA and the private key of the node can be used as the identity of the node, for example, for identity validity verification and the like.

In a block chain network of the commodity life cycle management system, each node can link up the information of a special commodity through an intelligent contract.

In some examples, the production node may uplink production information for a particular good. The production information for a particular commodity may include one or more of the following: the raw material type, raw material identification, raw material quantity, raw material purchase date, product type, production quantity and production date of the special commodity. In the technical scheme provided by the embodiment of the application, the node type of the production node is a production type.

In some examples, the administration nodes may include a sales node and a purchase node. The sales node can uplink the sales information of the special goods. The sales information for a particular article may include one or more of the following: the identification of the special commodity, the identification of the purchasing node, the type and the purchasing quantity of the special commodity, the license certification of the purchase, the sale contract and the purchase amount. Wherein the purchase permission certificate is generated for the management node. In the technical scheme provided by the embodiment of the application, the node type of the sales node is a sales class.

In some examples, the transportation node may uplink the transportation information for the particular goods. The shipping information for a particular good may include one or more of the following: transport vehicles, transport drivers, transport routes, transport item types, item identifications, item quantities, and transport permit proofs for specific goods. Wherein the transportation license is generated for the management node. In the embodiment of the present application, the node type of the transportation node is a transportation class.

In some examples, the storage node may uplink the stored information of the specific goods. The stored information for a particular article may include one or more of the following: the name and the position of the special commodity storage warehouse, the affiliated enterprise (or unit), the type of the stored special commodity, the identification of the special commodity, the number of the special commodity and the warehouse-in and warehouse-out machine account information.

In some examples, the user node may uplink the processing information of the specific product. The processing information of the special product may be operation information of the special product or disposal information of the special product. The processing information for the particular product may include one or more of the following: special commodity operating units, safety responsible persons, the types of special commodities, the identifications of the special commodities, the number of the special commodities, operating places and operating videos.

The block chain technology has the technical characteristics of irreversible time sequence, data tamper resistance and the like. The commodity life cycle management system can ensure that the circulation conditions of commodities are safely and reliably recorded according to the time sequence, and are consistent with or inhibited from the time sequence requirement of commodity circulation in the physical world. And the backtracking and positioning of each commodity flow direction occurrence point can be carried out in real time. In addition, the distributed storage and decentralized voting mechanism of the blockchain network can also improve the cost of tampering with the information of the commodity.

Through the introduction, the information of each life cycle of any special commodity in the block chain network can be linked by the corresponding node, so that the information of each life cycle of the special commodity can be guaranteed to be difficult to tamper or forge. The design can also support the inquiry of the production information, the sales information, the transportation information and the processing information of a special commodity by utilizing the identification of the special commodity.

In one possible design, the management node may provide a traceability service. Or the block chain network of the commodity life cycle management system can also comprise a source tracing node for providing information of each life cycle of the special commodity. In the following examples, the specific commodities are simply referred to as commodities.

The management node or the source tracing node can receive a query request of the target commodity identification. The management node or the tracing node may provide information of each life cycle of the product corresponding to the target product identifier to the node initiating the query request.

In some examples, the management node or the tracing node may provide one or more of the following to the node that initiated the query request: the commodity management system comprises production information of a commodity corresponding to a target commodity identification, transportation information of the commodity corresponding to the target commodity identification, storage information of the commodity corresponding to the target commodity identification, operation information of the commodity corresponding to the target commodity identification, and use information of the commodity corresponding to the target commodity identification.

In other examples, the management node or the tracing node may provide one or more of the following to the node that initiated the query request: the method comprises the steps of identifying the commodity corresponding to the target commodity identification according to the type of raw materials of the commodity corresponding to the target commodity identification, the type of the commodity corresponding to the target commodity identification, an enterprise (identification of a production node) for producing the commodity corresponding to the target commodity identification, the time for producing the commodity corresponding to the target commodity identification, the enterprise (identification of a purchase node) for purchasing the commodity corresponding to the target commodity identification, the enterprise (identification of a transportation node) for transporting the commodity corresponding to the target commodity identification, the time for transporting the commodity corresponding to the target commodity identification, the enterprise (identification of a storage node) for storing the commodity corresponding to the target commodity identification, the time for storing the commodity corresponding to the target commodity identification, the enterprise (identification of a use node) for using the commodity corresponding to the target commodity identification, and a video for using the commodity corresponding to the target commodity identification.

In a possible design, in the commodity life cycle management system provided in the embodiment of the present application, different processing permissions are configured for node types of different circulation nodes. If the production node has the production information entry authority of the special commodity but does not have the authority of purchasing the special commodity. For another example, the transportation node only has the right of inputting the transportation information of the special commodity, but does not have the right of producing, selling and using the special commodity. In an embodiment of the application, one node type is configured with one or more permissions.

Based on the product lifecycle management system provided in any of the above embodiments, the management node may execute the product lifecycle management method provided by the present application. FIG. 3 illustrates a method for merchandise lifecycle management, according to an exemplary embodiment, which may include the steps of:

step 301, a management node receives a permission request of a target node, where the permission request carries a node identifier, a permission type, and commodity information of the target node, and the commodity information includes an identifier, a category, and a quantity of a commodity.

In this embodiment, the target node may be any one of a production node, an operation node, a transportation node, a storage node, and a use node. The permission request may be any of: a production license request, a purchase license request, a transportation license request, a storage license request, an operation license request.

The node type of the target node may include one or more types. In the embodiment of the application, the permission request can carry a permission type. The license type characterizes a type of license credential information to which the license request corresponds. The license types can be classified into production, purchase, business, utility, and storage.

The license certification information may be understood as a license certification, or an electronic license certification. The merchandise information typically includes an identification of the merchandise, a category of each merchandise, and a quantity of each merchandise. The commodity information may be of different types. For example, the commodity information may include generation information of the commodity, management information of the commodity, use information of the commodity, transportation information of the commodity, and storage information of the commodity.

In one possible design, any node in the blockchain network, except the management node, has a unique corresponding management node. One management node may correspond to a node other than the management node in the plurality of blockchain networks. In order to distinguish from the management node, a node in the block chain network other than the management node is hereinafter referred to as a circulation node. The circulation node may be a production node, a transportation node, an administration node, a storage node, or a usage node. One management node may correspond to a plurality of streaming nodes.

Optionally, the correspondence between the management node and the streaming node may be configured in advance. In some examples, a unit to which a first management node belongs in a blockchain network belongs to a first administrative domain. In the multiple circulation nodes corresponding to the first management node, a unit (or enterprise) to which any node belongs to a second administrative area, and the second administrative area is the same as the first administrative area, or the second administrative area belongs to the first administrative area. The streaming node may send a permission request to its corresponding management node. The management node may generate license certification information of the streaming node corresponding thereto.

In one possible design, only one management node is included in a federation chain. And the plurality of circulation nodes corresponding to the first management node are in the same alliance chain with the first management node. One streaming node is in only one federation chain. The streaming node may send a permission request to a management node in a federation chain to which the streaming node belongs. The management node may generate license certification information for the streaming node in the federation amount to which the management node belongs.

Step 302, after determining that the node type of the target node matches the permission type, the management node generates permission information of the target node, where the permission information includes a permission certification number and the commodity information.

Each management node can acquire the node type of the target node. In some examples, the management node may query the node type of the target node according to the node identification of the target node. In other examples, the permission request of the target node may carry a node type of the target node, so that the management node may know the node type of the target node.

The management node may determine whether the type of the target node matches the type of the permission node. It is understood that the management node determines whether the target node has the right to submit the permission request.

In some examples, the node type of the target node matches the permission type if the node type of the target node includes the permission type. It will be appreciated that in this case, the target node has the right to submit the permission request. The management node may generate license information for the target node. Generally, the license certification information includes a license certification number and commodity information (identification, category, and number of commodities) carried in the license request.

In other examples, the node type of the target node does not match the permission type if the node type of the target node does not include the permission type. It will be appreciated that in this case the target node does not have the right to submit the permission request. The management node may not process the permission request or the management node may send a notification to the target node that the permission request fails to be approved.

Step 303, the management node signs the license certification information according to the private key of the management node.

Step 304, the management node uplinks the signed license information.

The management node signs the license information generated in step 302 by using its own private key, and chains the signed license information, which can prevent the license information of the commodity from being tampered, and can also make the license information of the commodity verifiable and queryable.

The license certificate information signature verification mode can adopt any existing signature verification mode. In some examples, the querying device may verify the signed license credential information using a public key of a management node of the license credential information. For example, the querying device may decrypt the signed license manifest information using the public key of the management node that provided the license manifest information to obtain the digest a. And performing hash processing on the signed license information by using a preset hash function to obtain the abstract B. If the digest A is consistent with the digest B, it can be determined that the license proves that the information is authentic and has not been tampered.

In one possible scenario, a production node may send a production admission request to a management node. As shown in fig. 4, the commodity life cycle management method may include the steps of:

step 401, the production node sends a production permission request, where the production permission request carries a node identifier, a permission type, and commodity information of the production node, where the permission type is a production type.

In the embodiment of the present application, the license type in the license request may be represented by different characters or numbers.

Step 402, the management node determines whether the node type of the production node matches the permission type in the production permission request, if yes, step 403 is executed, otherwise, the production permission request is not processed.

In step 403, the management node generates production license information, where the production license information includes a production license serial number, a node identifier of the production node, and commodity information.

In step 404, the management node signs the production license information according to the private key.

The management node may sign the generated production license certification information according to its own private key.

Step 405, the management node uplinks the signed production license information.

Optionally, the commodity life cycle management system provided in the embodiment of the present application may support verification of production license certification information of the production node. The client may send a first query request to the blockchain network, where the first query request carries the first node identifier and the permission type, where the permission type is a production class. Any node in the blockchain network may provide the client with the production license credential information (signed) identified by the first node. The client can verify the signed production license certification information by using the public key of the management node generating the production license certification information. In one possible design, the client may decrypt the signed production license credential information using the public key of the management node to obtain the first digest. And performing hash processing on the signed production license information by using a preset hash function to obtain a second abstract. If the first digest and the second digest are identical, it can be determined that the production license information is authentic and has not been tampered.

In one possible scenario, the purchasing node may send a purchase approval request to the managing node. As shown in fig. 5, the commodity life cycle management method may include the steps of:

step 501, a purchasing node sends a purchasing permission request, where the purchasing permission request carries a node identifier, a permission type and commodity information of the purchasing node, where the permission type is a purchasing type.

Step 502, the management node determines whether the node type of the purchase node matches the license matching type in the purchase license request, if yes, step 503 is executed, otherwise, the purchase license request is not processed.

In step 503, the management node generates purchase license information, which includes the purchase license number, the node identifier of the purchase node, and the commodity information.

Alternatively, the management node may mark the status of the purchase license credential number as valid.

And step 504, the management node signs the purchase license certification information according to the private key.

The management node may sign the generated purchase license certification information according to its own private key.

Step 505, the management node links the signed purchase license certification information.

In one possible design, in step 501, the purchase permission request also carries a label node identifier of the sales node. After the management node performs step 505, the following steps may also be performed:

at step 506, the management node sends the signed purchase license information to the sales node.

And step 507, the selling node uses the public key of the management node to sign and verify the signed purchase permission certification information.

In step 508, the selling node inquires whether the state of the license certification number of the purchase license certification information is valid, if yes, step 509 is executed, and if not, the process is ended.

The sales node may inquire the state of the license ticket number in the goods life cycle management system. If the status of the license credential number is marked as valid, step 509 is performed. If the state of the license certification number is marked as invalid, the process is terminated.
