Detailed Description

The technical solutions in the embodiments 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 only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Please refer to fig. 1, which is a schematic diagram of a system architecture according to an embodiment of the present application. As shown in fig. 1, the service server 10 and the service server 20 correspond to a participating entity in an item supply chain, which may include a place of origin, a manufacturer, a distributor, a retailer, and a consumer, for convenience of description and understanding, the service server 10 is referred to as a transferor node 10, the service server 20 is referred to as a receiver node 20, that is, the transferor node 10 transfers a target item to the receiver node 20, for example, the producer node transfers the target item to a brand node, and the brand node may serve as a transferor node, so as to transfer the target item to an agent node, that is, the receiver node in a previous transfer relationship may serve as a transferor node in a next transfer relationship, and by recording the transfer relationship of the target item and the time corresponding to the transfer relationship (including the time when the transferor node 10 transfers the target item to the receiver node 20, or the time at which the recipient node 20 receives the target item from the transferor node 10) to form a supply chain of the target item, the present application interfaces the supply chain of items formed by the participating bodies of circulation of the items with the blockchain storage system so that the item data of the upper chain is not tampered with.

Referring again to fig. 1, the service server 30 is a block link point 30, which may include the following functions: 1) when a new supplier a wants to transfer a target item in a higher-level agent B, it needs to first send a request for entering into a supply chain to the blockchain node 30, where the request for entering into a supply chain may include the type of the supply chain (e.g., food supply chain, living goods supply chain, traffic supply chain) and basic information of the new supplier a, and the basic information may include: the identity, address, contact way and the like of the new supplier A, the block chain link point 30 audits the new supplier A after obtaining the application chain entering request, if the audit is passed, a pair of public and private key pairs (the public and private key pairs of different participating bodies in different supply chains are different, namely the public and private key pairs have uniqueness) is sent to the new supplier A, the public key is added to the block chain, and if the audit is failed, a failure prompt is sent to the new supplier A; 2) identifying the identity of the node sending the request, wherein different participating agents have different participating functions, and cannot open the item data of the block chain for all participating agents, or most participating agents cannot acquire the item data of the target item in the block chain, otherwise, a counterfeit merchant can acquire the item data of the target item through the block chain, so that counterfeiting and faking are performed; for example, for an inquiry request sent by a customer end node, the block link point 30 may return an inquiry result, but cannot return real article data of a target article, as shown in fig. 1, the transferor node 10 and the receiver node 20 may send article data to the block link point 30, or may send an inquiry request or a check request to the block link point 30, if a new supplier a wants to transfer a target article in an agent B at a previous stage, an article transfer request carrying information of the new supplier a is sent to the block link point 30, after the block link point 30 obtains the article transfer request, the public key of the new supply chain a in the block chain is obtained, and the hash value (which may be generated by information of the new supply chain a) carried in the request is checked by using the public key of the new supply chain a, if the check is successful, the block link point 30 determines that the article transfer request is sent by a true new supplier a, if the signature verification fails, the block link point 30 determines that the sending of the article transfer request is a counterfeit new supplier a; 3) when a new supplier A wants to transfer a target article in an agent B at the upper level, the electronic tag (article data) of the different article at different time stamps is received, an article transfer request is sent to a block link point 30, the block link point 30 generates a target article hash value corresponding to the target article information according to the article transfer request, a first block which is associated with the target article information and has the largest block generation time stamp is obtained from a block chain, and a first article hash value of the first article information in the first block is obtained; if the target item hash value is the same as the first item hash value and the first receiver information in the first block is the same as the agent B information, and the block link point 30 can determine that the first item information is the same as the target item information, the target item information is sent to the new provider node a as legal information, so that the new provider node a can transfer the target item from the agent node B, and the block link point 30 generates a target block according to the target item information, the new provider node a information, and the agent B information, and uploads the target block to the block chain.

Referring to fig. 1 again, the service server 40 is a checking node 40 in the present application, and may include a node corresponding to a National quality certification center, a node corresponding to a National acceptance service for compliance Assessment (CNAS), or a node corresponding to a provincial and municipal level quality certification center, and the checking node 40 is different from a participating subject in a target item supply chain and may acquire item data in a block chain.

It can be seen that, the transferor node 10 or the receiver node 20 may send an article transfer request to the blockchain node 30, and after verifying the article transfer request, the blockchain node 30 generates a target block according to the article transfer request (which may include target article information, transferor information, and receiver information), and adds the target block to the blockchain; when the target object is acquired by the inspection node 40 and the target object is to be inspected, the target object information and the circulation route to be authenticated can be acquired by scanning the identification code on the target object, the target object information and the circulation route to be authenticated are sent to the block chain node 30, a series of target blocks can be acquired by the block chain node 30 according to the target object information, then the target circulation route of the target object is generated based on the series of target blocks, and the inspection result of the target object can be determined by the block chain node 30 according to the target circulation route and the circulation route to be authenticated.

The transfer node 10, the receiving node 20, the block link Point 30, and the verification node 40 may include a mobile phone, a tablet computer, a notebook computer, a palm computer, a smart audio, a Mobile Internet Device (MID), a POS (Point Of Sales) machine, a wearable device (e.g., a smart watch, a smart bracelet, etc.), and the like.

Further, please refer to fig. 2, which is a schematic view of a scenario of checking an item based on a block chain according to an embodiment of the present application. As shown in fig. 2, the inspection node 10 scans the identification code 20 of the target article through a scanning function to obtain an information set 30a corresponding to the target article, where the information set 30a may include target article information of the target article and a circulation route to be verified corresponding to the target article information, and if the inspection node 10 finds that the information set 30a has an obvious leak, such as missing manufacturer information, missing transfer party information, or the expiration date has passed, it may directly determine that the target article is unqualified for inspection; if the verifying node 10 does not find that there is an obvious error in the information set 30a, as shown in fig. 2, an article checking request is sent to the blockchain node 40, where the article checking request may include the information set 30a and the verifying node information 60, and the blockchain node 40 may determine the authenticity of the identity of the verifying node 10 according to the verifying node information 60 by the following specific process: according to the check node information 60, acquiring a public key of the check node 10 in the block chain, then checking a signature of a digital signature (which can be generated by the check node information 60) carried in the check node information 60 by using the public key of the check node 10, and if the signature fails to be checked, determining that the forged check node 10 is the check node which sends the article checking request by using the block chain link point 40; if the verification is successful, the block link point 40 determines that the checking node 10 sending the article checking request is a real checking node, in this scenario, the block link point 40 obtains at least one target block 50 from the block chain according to the target article information in the information set 30a, the at least one target block 50 is associated with the target article information, each target block includes a transfer relationship (transfer party-receiving party) of the target article and a transfer timestamp corresponding to the transfer relationship, the block link point 40 may generate a target transfer route 30b of the target article according to the at least one target block 50, compare the to-be-verified transfer route in the information set 30a with the target transfer route 30b, determine a checking result corresponding to the target article, if the to-be-verified transfer route in the information set 30a is the same as the target transfer route 30b, the inspection result of the target article information is determined to be qualified, if the circulation route to be authenticated and the target circulation route 30b in the information set 30a are different, the inspection result of the target article information is determined to be unqualified, and then the inspection result (the inspection result) of the article inspection request is returned to the inspection node 10.

Wherein the identification code may comprise an electronic label, a two-dimensional code or a bar code on the target item, in fig. 2 the identification code 20 is represented by a bar code.

Specifically, please refer to fig. 2 and fig. 4a together, and fig. 4a is a schematic diagram of an article inspection request according to an embodiment of the present application. As shown in fig. 2, the inspection node 10 scans an article identification code 20 corresponding to the target article to obtain target article information and a circulation route to be verified corresponding to the target article information, as shown in fig. 4a, where the target article information may include information such as an article name, an article type, an article raw material, an article number, a production date, a storage time, and a product manufacturer, and the circulation route to be verified includes a transfer party node, a receiving party node, and a timestamp for transferring the target article to the receiving party node by the transfer party node, such as transferring the article XXX to a brand provider node by the original node at 10 am 45 of 2019, 4/21; optionally, the article inspection request may further include information of the inspection node 10, such as the inspection node information 60 in fig. 2, for action, see the corresponding description in fig. 2, which is not described herein again. The inspection node 10 sends the item ping request to the blockchain node 40, and the blockchain node 40 obtains at least one target block 50 from the blockchain according to the target item information.

The at least one target block includes the target item information and a circulation record to which the target item information belongs, and a target circulation route corresponding to the target item information is described by taking two target blocks of the at least one target block as an example, please refer to fig. 4b together, which is a schematic flow diagram for generating a target circulation route according to an embodiment of the present application. As shown in fig. 4b, the target block 501 contains a first flow record, the first flow record may contain origin node information (first transferor node information), brand name node information (first receiver node information), and a transfer timestamp of the origin-source transfer target item to the brand name node (first flow timestamp), the target block 502 contains a second flow record, the second flow record may contain brand name node information (second transferor node information), total proxy node information (second receiver node information), and a transfer timestamp of the brand name node transfer target item to the total proxy node (second flow timestamp), and the transferor node of the target block 502 is the receiver node of the target block 501, the block link points generate a part of the flow route of the target flow route according to the target block 501 and the target block 502, as shown in fig. 4 b.

And step S103, matching the circulation route to be verified with the target circulation route, and determining a detection result corresponding to the target article information according to the matching result.

Specifically, referring to fig. 4a and 4b together, a to-be-verified circulation timestamp (e.g., 2019.04.2110: 45 and 2019.05.0110: 00 in fig. 4 a) and a to-be-verified circulation mechanism (e.g., the origin node, the brand provider node, and the total agent node in fig. 4 a) of the to-be-verified circulation route are obtained, and a circulation timestamp and a circulation mechanism in the target circulation route are obtained; matching the to-be-verified circulation timestamp with the circulation timestamp in the target circulation route to obtain a timestamp matching result; matching the circulation mechanism to be verified with the circulation mechanism in the target circulation route to obtain a mechanism matching result; if the timestamp matching result is that the to-be-verified circulation timestamp is the same as the circulation timestamp in the target circulation route, and the mechanism matching result is that the to-be-verified circulation mechanism is the same as the circulation mechanism in the target circulation route, determining that the inspection result of the target article information is qualified in the inspection; if the timestamp matching result is that the to-be-verified circulation timestamp is different from the circulation timestamp in the target circulation route, or the mechanism matching result is that the to-be-verified circulation mechanism is different from the circulation mechanism in the target circulation route, determining that the inspection result of the target article information is that the inspection is unqualified; if the inspection result is that the inspection is qualified, sending inspection qualified information to the inspection node; and if the inspection result is that the inspection is not qualified, sending abnormal prompt information to the inspection node, wherein the abnormal prompt information is used for indicating the inspection node to carry out failure processing on the target object.

As shown in fig. 6, when the agent node 3a wants to transfer the target article to the retailer B, it sends an article transfer request 30 to the block link point 40 according to the target article information, the transfer party information, and the receiving party information, where the article transfer request 30 includes the target article information such as the article number, the production date, and the storage time, the information of the agent a itself, and the information of the retailer B; after acquiring the article transfer request, the block chain node 40 generates a corresponding target article hash value according to the target article information, as shown in fig. 6, where the target article hash value corresponding to the target article information is 2158c9314adca40831da9240580-ec 600.

Step S202 is to acquire a first block associated with the target item information and having a maximum block generation timestamp from the block chain, and acquire a first item hash value of first item information in the first block.

Specifically, referring to fig. 6, the blockchain node 40 obtains the first block (block 400a in fig. 6) associated with the target item information and having the largest block generation timestamp from the blockchain, and obtains the first item hash value of the first item information in the block 400 a.

Step S203, if the hash value of the target article is the same as the hash value of the first article, and the first receiving party information in the first block is the same as the forwarding party information, transmitting the legal information of the target article to the forwarding party node; the target article legal information represents that the target article information belongs to legal information.

Specifically, referring to fig. 6 together, after the first article hash value and the target article hash value are obtained, the first article hash value and the target article hash value are compared, if the first article hash value and the target article hash value are the same (as shown in fig. 6, both of them are 2158c9314 aca 40831da9240580ec600), and the first receiving-side information in the first block 400a is the same as the transfer-side information in the article transfer request, the block link node 40 determines that the target article information is the first article information, so as to send the transfer-side node the target article legal information, and if the first article hash value and the target article hash value are not the same, the block link node 40 determines that the target article information is not the first article information, so as to send the transfer-side node the target article information illegal information.

Step S204, generating an object block according to the object item information, the transferor information, and the receiver information, and uploading the object block to the block chain.

Specifically, as described in step S203, after the blockchain link node 40 determines that the target item information is the first item information, the blockchain node 40 generates a target block by using the target item information, the transferor information, and the receiver information, and adds the target block to the blockchain for query or verification.
