Detailed Description

To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

Fig. 1 is a schematic diagram of an implementation environment related to an information management method for a block chain according to an embodiment of the present application. As shown in FIG. 1, the implementation environment may include: the blockchain network 10 includes a plurality of nodes 101 (only 4 nodes are shown in fig. 1) that are mutually established with communication connections, and information can be transmitted between the nodes 101 through the established communication connections. Also, each node 101 may include a plurality of tiles, and each node 101 may store received information to its tiles and broadcast received data to other nodes 101. Alternatively, each node 101 may be a computer device, for example, referring to fig. 1, the computer device may be a server, or may also be a terminal device such as a computer or a mobile phone.

In an embodiment of the present application, an intelligent contract may be deployed in the blockchain network 10, where the intelligent contract refers to a computer protocol that is intended to propagate, verify, or execute contracts in an informational manner. Each node 101 may receive information input from the information provider via the smart contract, store the received information in a block therein, and broadcast the received information to the entire network via the smart contract, so that other nodes 101 may also receive the same information (this process may also be referred to as uplink). And, in order to implement the information query function, each node 101 may also read information stored in the blockchain network 10 through the intelligent contract. In addition, for each node 101, it may further have a node identifier corresponding thereto, and may store node identifiers of other nodes in the blockchain network 10, so that each node 101 may reliably broadcast the received information to other nodes through the communication connection according to the node identifiers of other nodes.

For example, referring to table 1, a node identification list maintained in each node 101 is shown, which may include: node name and node identification. The node identifier may be an Internet Protocol (IP) address and any other information that can be used to identify the node, and table 1 only illustrates the IP address as an example. For example, referring to table 1, the node name is node 1, and the node identifier corresponding to the node 1 is: 117.114.151.174.

TABLE 1

Node name	Node identification
		Node 1	117.114.151.174
Node 2	117.116.189.145
		…	…
Node N	119.123.789.258

In addition, in order to ensure the consistency of the information stored by each node 101, each node 101 may also maintain the entire blockchain network 10 through an intelligent contract based on a set of consensus mechanisms. That is, the nodes 101 may perform data correction for multiple times through a pre-configured consensus algorithm, and continuously broadcast the data corrected for the last time to the whole network until the information stored by the nodes 101 is consistent, that is, until the nodes 101 achieve consensus. The principle of the consensus algorithm comprises the following steps: the node receiving the information compares the received information with the information stored by the node, and re-broadcasts the information with the accuracy rate larger than the accuracy rate threshold value in the plurality of information determined after comparison to the whole network; then, the node receiving the corrected information continues to repeatedly execute the comparison operation, namely, network diffusion iteration is carried out until the whole network is agreed.

It should be noted that the blockchain network 10 may be a decentralized network system, i.e., commodity information may be supervised by the blockchain network 10 through a decentralized technique. Wherein, decentralization means: there is no concept of a central node in the blockchain network 10, the positions of the nodes 101 in the blockchain network 10 are equal, each node 101 may store the same blockchain, each blockchain includes a plurality of blocks, each block stores different data, and the data stored in all the blocks on the blockchain constitute all the shared data of the blockchain network.

In addition, since the corresponding product information includes not only manufacturing information but also physical distribution information, sales information, and the like for one product, the product information is comprehensively managed. Taking a device (e.g., an electronic device) as an example, referring to fig. 2, in the embodiment of the present application, a component manufacturing factory that manufactures components of the device, a device assembly factory that obtains the device based on component assembly, a logistics unit (including a customs unit) that transports the device, and a sales store (including a network sales store) that sells the device may all join the blockchain network 10. Of course, the purchaser may also join the blockchain network 10 through its terminal. It should be noted that fig. 2 only illustrates a block chain composed of a plurality of blocks (5 blocks are shown in fig. 2) in one node 101, and after the use of a block storage space is completed, the node 101 may store the received information to another block, where the time represents the time for storing the information.

Since the operations performed by the blockchain network 10 are: the commodity information and the inquiry commodity information are recorded, and the user who buys the commodity can inquire the commodity information of the commodity bought by the user in the block chain network and reliably distinguish the authenticity of the commodity bought by the user according to the inquired commodity information. The blockchain network may also be referred to as a device anti-counterfeiting traceable platform. The information is managed through the block chain technology, the advantages that the block chain network cannot be tampered, cannot be forged, data encryption is reliable, sharing is open and the like can be effectively utilized, and effective and safe management of the information is achieved. Compared with the related art that the information is managed through the database, the management method enables the reliability of information query to be higher.

For example, a user who purchases a commodity can reliably inquire the commodity information of the commodity he purchases in the blockchain network, and then a buyer can reliably judge the authenticity of the commodity he purchases according to the commodity information. And the user can clearly inquire whether the equipment is sold for the second time according to the commodity sales information. The method and the system bring guarantee to original manufacturers who really manufacture the commodities and users who buy the commodities.

Fig. 3 is a flowchart of an information management method for a block chain according to an embodiment of the present application. May be applied to any node comprised in the blockchain network shown in fig. 1. As shown in fig. 3, the method may include:

step 301, when receiving the commodity information provided by the information providing terminal, performing identity verification on the identity of the information providing terminal.

Wherein the information provider can be any party participating in the blockchain network. For example, referring to fig. 2, the information provider may be a component manufacturing foundry. The commodity information may be any information related to the commodity, such as production information or sales information of the commodity. The commodity information may be information that is set for the commodity in advance by the information providing terminal, such as a commodity identification for uniquely identifying the commodity.

In the embodiment of the application, the information providing terminal can input commodity information related to commodities to any node through the terminal device, that is, the node can receive the commodity information provided by the information providing terminal. In addition, in order to avoid that illegal molecules provide false information randomly in the block chain network and ensure the safety and reliability of information management, when the nodes receive commodity information, identity verification can be carried out on the information providing end through an intelligent contract.

And step 302, broadcasting the commodity information in the block chain network when the identity verification is passed.

When the identity authentication is passed, the node of the received commodity information can continue to store the commodity information into one block in the node through the intelligent contract and broadcast the received commodity information to the whole block chain network, namely the node of the received commodity information can transmit the commodity information to other nodes through communication connection established with other nodes, so that each node can store the commodity information. This step may also be referred to as uplink operation, i.e., the node uplinks the merchandise information.

Optionally, in order to ensure consistency of information stored in each node, each node that receives the commodity information may further perform consensus processing on the commodity information through a consensus algorithm, and then broadcast the commodity information to the whole network again, and continuously perform the consensus processing until the commodity information stored in each node is consistent.

Step 303, when receiving a query request of the information request terminal for any commodity information in the block chain network, acquiring any commodity information.

In the embodiment of the present application, the information request end may be not only any participant who joins the blockchain network, but also other users (such as a purchaser who purchases goods) besides the participant. If the commodity information needs to be inquired, a user (namely, the information request terminal) for inquiring the commodity information can input the relevant information of the commodity to be inquired into the node through the terminal, and correspondingly, the node can receive the inquiry request of the information request terminal. When receiving the query request, the node can acquire any commodity information corresponding to the query request in the block chain network through the intelligent contract.

Step 304, providing any commodity information to the information request terminal.

Optionally, when the node queries the commodity information according to the query request, the node may directly display any queried commodity information to the information request terminal, so that the information request terminal can obtain the commodity information that the information request terminal wants to query.

In summary, the embodiment of the present application provides an information management method for a block chain. Any node of the pre-established block chain network can receive commodity information provided by an information providing end, and when the identity of the information providing end is verified and the verification is passed, the received commodity information is broadcasted to the whole network, so that all nodes included in the block chain network can store the same commodity information. And the node can also receive a query request aiming at any commodity information and provide the queried commodity information to the information request terminal according to the request. The information is stored and managed through the block chain network technology, and compared with the related technology which adopts database management, the method can fully utilize the advantages of non-falsification, safety, reliability and the like of the block chain, ensure the reliability of information management, and further ensure the reliability of true and false identification according to the inquired information.

Fig. 4 is a flowchart of another block chain information management method according to an embodiment of the present application. The method may be applied in any node of the blockchain network shown in fig. 1. As shown in fig. 4, the method may include:

step 401, when receiving the commodity information provided by the information providing end, detecting whether a commodity identifier is stored in the block chain network.

In the embodiment of the present application, the information provider may be any party participating in the blockchain network. For example, referring to fig. 2, the information provider may include at least one of a component manufacturing factory, an equipment assembly factory, a logistics unit, and a sales outlet. The commodity information may be information that is set in advance for a commodity by any one of the parties. The information providing terminal can input the commodity information into any node through the terminal equipment, and correspondingly, the node can receive the commodity information provided by the information providing terminal.

The commodity information may include a commodity identifier, where the commodity identifier may be an identifier (also referred to as a commodity branding identifier) that is set for the commodity and is used for uniquely identifying the commodity before the participant links the commodity information, and the commodity identifier may include at least one of numbers, letters, and special symbols.

Optionally, when the participant includes a plurality of participants shown in fig. 2, the item identifier may include: at least one of a part identifier, an equipment identifier, a logistics identifier, and a sales identifier. When the participating party is the component manufacturing original factory, the commodity identifier may be an identifier set for the component manufacturing original factory to produce the component after the detection quality is qualified, for example, the commodity identifier set for the component manufactured by the component manufacturing original factory is: lj 0000001. When the participant is the equipment assembly factory, the commodity identifier may be an identifier set for the equipment after the equipment is assembled by the equipment assembly factory, for example, the commodity identifier set for the equipment assembled by the equipment assembly factory is: sb 0000009. When the participant is a logistics unit, the commodity identifier may be an identifier set for the logistics situation after the logistics unit transports the device, for example, the logistics identifier set for the device transported by the logistics unit is: wl 0000005. When the participant is a sales store, the article identifier may be an identifier set by the sales store after selling the device, for example, the sales identifier set by the sales store for the device it sells is: xs 0000006.

In order to avoid the problem that false information is provided by illegal molecules or the problem that the information management efficiency and the safety are low due to the fact that the participator repeatedly provides information, after the node receives commodity information, whether the received commodity identification is stored in the block chain network or not can be inquired in the block chain network through an intelligent contract. If the node detects that the commodity identification included in the received commodity information is stored in the block chain network, the node can directly quit the uplink operation and the uplink fails. If the product identifier is not stored in the blockchain network, the uplink operation of the product information may be continued, i.e., the following step 402 may be continued.

Step 402, performing identity verification on the identity of the information providing terminal.

In the embodiment of the application, in order to further avoid that illegal molecules provide false information randomly in a block chain network and ensure the safety and reliability of information management, when the nodes receive commodity information, identity verification can be performed on an information providing end through an intelligent contract.

Optionally, the commodity information received by the node may further include: a digital certificate and a digital signature provided by the participant. The digital certificate can be a certificate which is applied by a participant to an authority in advance and is used for uniquely indicating the identity of the participant, and the digital certificate can be disclosed to all users, namely all users can authenticate that the certificate is issued by the authority. For example, the Authority may be a Certificate Authority (CA) Authority, and the parties may provide their public keys to the CA Authority, from which the CA Authority may issue digital certificates to the parties. The digital signature can be signature information obtained by signing the commodity information by a private key of a participant.

Since the private key is only held by the participant, the node can authenticate the identity of the information provider through the digital certificate and the digital signature. For example, the node may determine a public key through a digital certificate included in the received commodity information, match the public key with a private key corresponding to the digital signature, and if the matching is successful, determine that the authentication of the information provider is successful. At this time, the node may uplink the commodity information, that is, the node may continue to perform the following step 403. If the matching fails, the node may determine that the identity verification fails, at which point the node may exit the uplink operation and the uplink fails. Of course, the identity of the information provider can also be verified in other encryption manners.

For example, assume that the digital certificate includes public keys of: x0010, and the private key matched with the public key is x 0020. However, if the private key corresponding to the digital signature received by the node is x0011, the node can determine that the public key of the digital certificate and the private key of the digital signature are not matched, and the authentication fails. By carrying out identity verification on the identity of the information providing end, lawbreakers can be prevented from uploading false information at will, and the safety of information management is ensured. Furthermore, the inquirer can inquire the real information, and the authenticity tracing reliability is improved.

It should be noted that, in this embodiment of the application, the step 401 may not be executed, that is, when the node receives the commodity information, the node may directly execute the operation of the identity authentication.

And step 403, broadcasting the commodity information in the block chain network.

In the embodiment of the present application, in order to facilitate that each node of the entire blockchain network can store the same commodity information, when the identity authentication passes, the node of the received commodity information can uplink the received commodity information. That is, the node of the received commodity information may store the received commodity information into one block included therein through the intelligent contract, and may broadcast the received commodity information to the whole network, and the node of the received commodity information may store the commodity information into one block included therein through the intelligent contract. And finally, storing the same commodity information in each node added into the block chain network.

Optionally, the uplink commodity information may include key information and value information, that is, the data format of the commodity information provided by the information providing end may be key _ value. The key information may include the product identifier recorded in step 401, and the value information includes at least one of a digital certificate, a digital signature obtained by signing the value information with a private key corresponding to the digital certificate, and product data. The commodity data may include at least one of part data, equipment data, logistics data, and sales data.

The part data may include the time of leaving the factory, the name of the original factory of the part production, the name of the part, and the like; the equipment data may include equipment delivery time, names of components of the equipment, names of original equipment assembly plants, and the like; the logistics data may include a name of a logistics unit; the sales data may include the name of the sales store, the time of sale, and the like. It is to be understood that the description is merely exemplary, and the product data includes not only the data described in the embodiments of the present application.

For example, referring to fig. 5, the information provider includes a component manufacturing factory, an equipment assembly factory, a logistics unit, and a sales store, which are taken as examples, and a schematic diagram of the commodity information of a commodity after being linked on the node is shown. As shown in fig. 5, the goods identifier received by the node includes: part identification (id), device id, logistics id, and sales id. The value information corresponding to the part identification id includes: part id, part delivery time (belonging to commodity data), digital certificate, and digital signature. The value information corresponding to the device id includes: the device id, the id of each part used for assembling the device, the factory time (belonging to commodity data) of the device, the digital certificate and the digital signature. The value information corresponding to the logistics id includes: logistics id, equipment id, logistics information (belonging to commodity data), digital certificate and digital signature. The value information corresponding to the sales id includes: sales id, device id, digital certificate, and digital signature. Alternatively, the value information may not include id information included in the key information.

It should be noted that, when the information providing end assembles the original factory for the device, the node may further continue to detect, through the smart contract, whether the received information related to the component is already used on another device after the step 402 is performed. Stopping the uplink if the uplink is used; if not, the following step 403 is continued. In addition, when the information providing end is a sales store, the node may detect whether a sales record of the device exists in the block chain network through an intelligent contract before the node links the chain, and if the sales record exists, the node may further display a prompt message to the information providing end for prompting that the device is sold, so that the user can clearly know the sales condition of the device, and then continue the chain linking, that is, continue to perform step 403.

Step 404, when receiving a query request of the information request terminal for any commodity information in the block chain network, acquiring any commodity information.

Alternatively, the information request end can be not only any participant joining the blockchain network, but also other users (such as a buyer purchasing goods) besides the participant. If the commodity information needs to be inquired, a user (namely, the information request terminal) for inquiring the commodity information can input the relevant information of the commodity to be inquired into the node through the terminal, and correspondingly, the node can receive the inquiry request of the information request terminal. When receiving the query request, the node can acquire any commodity information corresponding to the query request in the block chain network through the intelligent contract. It should be noted that the information requesting end in step 404 and the information providing end in step 401 may execute operations on the same node, or may execute related operations on different nodes, which is not limited in this embodiment of the application.

Optionally, since the general information requesting terminal is easier to directly obtain the product identifier, and when the product information includes key information and value information, the corresponding value information can be directly queried through the key information. Therefore, in order to improve the query efficiency, the key information may include the commodity identification, and the query request may include the key information, that is, the query request may include the commodity identification. For example, referring to fig. 5, when receiving key information, a node may obtain a series of value information corresponding to the key information. Since the purchaser can inquire the commodity information through the commodity identification, the commodity identification can also be called a traceable code.

For example, it is assumed that the information requesting end is a user who purchases a commodity, and the user inputs a commodity identifier of the commodity purchased by the user to the node through the terminal device of the user, and accordingly, the node can receive a query request of the user for commodity information of the commodity. At this time, the node may obtain all commodity information related to the commodity in the block chain network through the intelligent contract, for example, may obtain commodity information corresponding to the part of the commodity, commodity information corresponding to the device, commodity information corresponding to the logistics, and commodity information corresponding to the sales, as shown in fig. 5.

Step 405, providing any commodity information to the information request terminal.

After the node queries the commodity information according to the query request, the queried commodity information can be provided for the information request terminal, so that a querier can obtain the commodity information which the querier wants to obtain. Optionally, when the commodity information includes key information and value information and the query request carries the key information, the value information is queried by the node according to the query request, and correspondingly, the queried value information can be provided by the node to the information request terminal.

The commodity is taken as electronic equipment, and the information providing end added into the block chain network comprises an original part manufacturing factory, an original electronic equipment assembling factory, a logistics unit and a sales store/buyer as examples to introduce the information management process of the block chain. Fig. 6 is a schematic diagram of an electronic device chain according to an embodiment of the present disclosure.

As shown in fig. 6, before providing the commodity information to the node, the component manufacturing factory may perform operations of producing the component, detecting whether the quality is acceptable, and performing branding (i.e., setting the component id for the component) on the component when the quality is acceptable, and may reproduce the component when the quality is not acceptable. Then, the component factory may provide the generated components to the electronic equipment assembly factory, and may serve as an information provider to record and link the commodity information (i.e., the component information shown in fig. 6) corresponding to the components. I.e., inputting the component information to the node.

After receiving the component provided by the component factory, the electronic device factory may first serve as an information request end to query commodity information of the component in the blockchain network (the specific query method may refer to step 404) to detect whether the component is a component of the factory. When detecting that the part is a factory part, an electronic equipment assembly factory can use the part to perform an operation of assembling the electronic equipment; when detecting that the part is not the original part, the winding can be stopped directly. After assembling the electronic device, the electronic device assembly factory may continue to label the electronic device it produces (i.e., set the device id for the device). Then, the electronic equipment assembly factory can provide the electronic equipment produced by the electronic equipment assembly factory to a logistics unit, and can be used as an information providing terminal to record and link commodity information (i.e. the electronic equipment information shown in fig. 6) corresponding to the electronic equipment. I.e. inputting electronic device information to the node.

After receiving the electronic device provided by the original factory assembled by the electronic device, the logistics unit may first serve as an information request end to query the commodity information of the electronic device in the blockchain network (the specific query method may refer to step 404) to detect whether the electronic device is an original factory device. When the electronic equipment is detected to be original factory equipment, the logistics unit can perform goods distribution and supply operation, namely, the electronic equipment is distributed to a sales store or a buyer; when detecting that the equipment is not original factory equipment, the uplink can be stopped directly. After distribution, the logistics unit can serve as an information provider to link the logistics information. I.e. logistics information is input to the nodes.

The store/buyer can execute the operation of buying and selling the electronic device, and can be used as an information requesting end to verify whether the electronic device bought and sold by the store/buyer is the genuine product and whether the electronic device is sold for the second time through the blockchain network (i.e. verifying the quality of the genuine product, tracing the production and supply links as shown in fig. 6). The store/buyer can then link up the purchase information record, i.e., enter the purchase information into the node. Through the operation shown in fig. 6, that is, a tracing platform for goods is established, the user can query the uplink information in the blockchain network according to the information of the goods purchased by the user.

It should be noted that, the order of the steps of the information management method for a block chain provided in the embodiment of the present application may be appropriately adjusted, for example, the step 401 may be deleted, or the step 404 and the step 405 may be executed synchronously. Any method that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present application is also covered by the present application, and thus, the detailed description thereof is omitted.
