In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The block chain technique is also called a distributed book technique, and is a distributed internet database technique. A network constructed based on the blockchain technology may be referred to as a blockchain network, where the blockchain network includes a plurality of blockchain nodes, each node corresponds to at least one blockchain, and each blockchain includes at least one block. The block chain technology has the characteristics of decentralization, openness and transparency, no tampering, trustiness and the like, so that the block chain technology is more and more widely applied.
Referring to fig. 1, fig. 1 is a block chain network architecture model according to an embodiment of the present invention. As shown in fig. 1, the blockchain network 100 includes a data layer 11, a network layer 12, a consensus layer 13, and an intelligent contract layer 14.
The data layer 11 encapsulates the underlying data blocks and associated basic data and basic algorithms such as data encryption and time stamping. The network layer 12 includes a distributed networking mechanism, a data propagation mechanism, a data validation mechanism, and the like. The consensus layer 13 encapsulates various kinds of consensus algorithms for the network nodes. Intelligent contract layer 14 encapsulates various types of scripts, algorithms, and intelligent contracts.
The commodity anti-counterfeiting tracing method based on the blockchain can be executed in any suitable type of blockchain nodes with calculation capability, such as servers, desktop computers, smart phones, tablet computers and other electronic products. The server may be a physical server or a logical server formed by virtualizing a plurality of physical servers. The server may also be a server cluster formed by a plurality of servers capable of communicating with each other, and each functional module may be respectively distributed on each server in the server cluster.
The commodity anti-counterfeiting tracing device based on the block chain can be used as a software system and independently arranged in the block chain node, and also can be used as one of the functional modules integrated in the processor to execute the commodity anti-counterfeiting tracing method based on the block chain.
The Block chain provided by the embodiment of the invention comprises a Public Block chain (Public Block Chains), a joint Block chain (Consortium Block Chains) and a Private Block chain (Private Block Chains).
Referring to fig. 2, fig. 2 is a schematic structural diagram of a block chain system according to an embodiment of the present invention. As shown in fig. 2, the blockchain system 200 includes a client 20, a normal node 21, a proxy node 22, and a consensus node 23.
The client 20 is connected with the common node 21 in a communication way, the common node 21 is connected with the agent node 22 in a communication way, and the agent node 22 is also connected with the consensus node 23 in a communication way. The communication between each blockchain node supports a Point-to-Point communication (P2P).
The client 20 is used for collecting information of the client, and the client 20 comprises a consumption terminal or a supplier terminal. The clients 20 are each configured with various types of electrical components, such as a controller, a camera component, an audio component, and so forth. When the client 20 is used as a consumption terminal such as a mobile phone, a smart watch, or the like, a user may scan the anti-counterfeiting tracing two-dimensional code attached to a commodity using the client 20, adjust the anti-counterfeiting tracing two-dimensional code to a content server corresponding to a website, and pull an anti-counterfeiting tracing page from the server. In some embodiments, when the client 20 obtains the anti-fake tracing website for accessing the content server, it may send the anti-fake tracing website to the common node 21, so that the common node 21 accesses the content server according to the anti-fake tracing website and pulls an anti-fake tracing page from the content server, where the anti-fake tracing page records information of each link of the commodity.
When the client 20 is used as a provider terminal, each provider can upload the anti-counterfeiting traceability link information to the common node 21 through the client 20. The ordinary node 21 packages the anti-counterfeiting traceability link information uploaded by each supplier into original block data, and sends the original block data to the agent node 22.
The normal node 21 holds the circulated electronic money and has the right to vote in the blockchain system. The common node 21 can perform related transaction operations, but has no block packaging accounting right, and can only synchronously record block data from the related node with the packaging accounting right.
In some embodiments, the common node 21 may also perform verification for anti-counterfeit tracing.
The agent node 22 is written with an intelligent contract code, and the normal node 21 sends the original data of the block to the agent node 22, and triggers the intelligent contract of the agent node 22, so that the intelligent contract of the agent node executes the original block data. Wherein the ordinary node 21 maintains an intelligent contract list that records a list of the respective agent nodes that 1 is capable of executing an intelligent contract. Each time the ordinary node 21 receives the original data of the block, the ordinary node 21 calls up the intelligent contract list, finds out the address of each proxy node from the intelligent contract list, and sends the original block data to each proxy node.
In this embodiment, the agent node 22 may pre-store multiple types of intelligent contracts, and may parse the execution type of the intelligent contract according to the trigger request sent by the common node 21. The agent node 22 executes the corresponding intelligent contract according to the execution type of the analyzed intelligent contract.
When a certain proxy node goes into fault, the other proxy nodes broadcast the address of the certain proxy node to the whole network, the common node 21 monitors the broadcast information and updates the intelligent contract list, and when the original data of the block is sent subsequently, the common node 21 does not send the data to the certain proxy node 22, so that the working efficiency is improved.
The code of the intelligent contract is written according to business scene logic, for example, in an unmanned store, the intelligent contract can be used for verifying anti-counterfeiting traceability information.
After executing the original block data according to the intelligent contract, the agent node 22 outputs the block data to be verified. Then, the proxy node 22 also signs the block data to be verified, and packages and sends the signed block data to the consensus node 23. The consensus node 23 verifies the signed block data using the public key of the proxy node 22, and if the verification is successful, the signed block data is considered to be sent by the valid proxy node 22, and then performs consensus processing on the block data. If the verification is not successful, the signed block data is considered to be sent by the illegal proxy node 22. For example, the proxy node 22 uses its private key to perform a signature operation on the hash content of the current block, and obtains the signature.
The consensus node 23 is used for consensus of the block data uploaded by the authentication proxy node 22. The consensus node 23 may support any one of the following consensus algorithms: proof of Work (PoW), Proof of rights of interest (POS), Proof of equity authorization (Delegate Proof of stamp, DPoS), Practical Byzantine Fault Tolerance (PBFT), authorized Byzantine Fault Tolerance (DBFT), and so forth.
Each of the consensus nodes 23 needs to register with the agent node 22, and after successful registration, the consensus node is a valid consensus node. The registration process is as follows:
1. the consensus node 23 submits the registration information to the proxy node 22.
Wherein the registration information includes one or more of the following: the device serial number SN, the user information and the miner wallet address of the consensus node 23.
2. The proxy node 22 checks the registration information.
The checking process comprises the following steps: it is checked whether the SN numbering format is correct, whether the SN is present in a database, whether the SN has been bound to other users, etc.
3. The proxy node 22 records the registration information.
4. The proxy node 22 returns the registration result to the consensus node 23.
5. The proxy node 22 broadcasts the new registration data to the blockchain system 200.
In the block chain system 200, the blocks are carriers for storing transaction summary information, each block includes a block header and a block body, and the information recorded in the block header is used to identify the block itself, the information summary of the previous block, and the position of the block in the whole account. The block body is used for storing the transaction summary information and verifying the transaction information and keeping the transaction from being tampered.
The block chain is formed by connecting each block one by one according to the sequence of the generation time. In the whole block chain, the first block is called a created block, the block height of the created block is 0, the block height of each subsequent block is sequentially added with 1, and the hash value of the previous block header is written in the block header. And all blocks on the block chain are linked by the last block head hash value on each block.
Therefore, the block chains have non-tamper-proof properties. Based on the above, the embodiment of the invention provides a commodity anti-counterfeiting tracing method based on a block chain, which is applied to an unmanned store.

The predetermined area is specifically the area within the product area proximate the first outlet 31 through which a user may only enter the checkout area 30. Thus, when the presence of the user's sensing signal is detected within the predetermined area, this is an indication that the user wants to leave the unmanned store, and the current status is to enter the checkout area 30.
The camera 34 includes a plurality and is provided in the unmanned store 300, which is specifically provided in the checkout area 30, at the first exit 31, at the second exit 32, at the entrance of the unmanned store 300, and in the goods area, and the like. The camera 34 is used to capture user images and send the captured user images to the processor 36.
In some embodiments, camera 34 may track the motion trajectory of the same user. For example, after the user a enters the unmanned store and is photographed at the entrance of the unmanned store 300, the image of the user a is photographed by the camera 34 corresponding to the area according to the activity area of the user a in the unmanned store 300, the image acquisition of the user a is not finished until the user a leaves the unmanned store 300, and after all the images of the user a in the activity in the unmanned store are acquired, the motion trajectory of the user a can be analyzed according to the sequence of the image acquisition, so that the user a can be accurately identified according to the motion trajectory, and the category of the goods purchased by the user a can be analyzed.
The rf read-write device 35 is used to identify whether a good is present in the checkout area and also to read information of the good purchased by the user, including the price of the good, the name of the good, the category of the good, etc. The rf read/write device 35 sends the read commodity information to the processor 36.

As previously described, the hash list is pre-constructed and verified with consensus. When the hash list is verified, the following processes are included:
first, the common node obtains link information uploaded by a provider corresponding to each link in each commodity, for example, the provider uploads the link information using a provider terminal, and the provider terminal sends the link information to the common node.
In some embodiments, in the process of acquiring link information uploaded by a provider corresponding to each link in each commodity, the common node receives an information request sent by a client of the provider, the information request carries a first certificate and link information, and the block link point stores a second certificate. Secondly, the common node judges whether the second certificate unlocks the first certificate or not according to the information request; if yes, receiving link information; if not, link information is not received.
In this way, it can be ensured that the link information uploaded by the receiving provider is legal.
Secondly, the common node sends each link information uploaded by each supplier to the agent node, the agent node performs hash operation on all link information of each commodity to calculate the real hash value of the commodity, and the real hash values corresponding to each commodity are clustered to form a hash list.
In the process that the agent node performs hash operation on all link information of each commodity and calculates the real hash value of the commodity, firstly, the agent node counts the link uploading times of each commodity, for example, an anti-counterfeiting traceability page of the commodity A comprises 5 links, a supplier is required to upload link information of 5 different links, and when the supplier uploads the link information of one link, the agent node accumulates the link uploading times of the commodity. Secondly, when detecting that the counted link uploading times of each commodity are equal to the preset link time threshold, the agent node performs hash operation on all link information of each commodity to calculate the real hash value of the commodity, for example, as mentioned above, when the link uploading times of the commodity are equal to 5, the agent node performs hash operation on all link information of each commodity to calculate the real hash value of the commodity. And thirdly, when the agent node does not detect that the counted link uploading times of each commodity are smaller than the preset link uploading times threshold value, continuing to monitor and count the link uploading times of each commodity.
For example, for commodity K: the link information of the raw material link is Y1, the link information of the production link is Y2, the link information of the storage link is Y3, and the link information of the logistics link is Y4, so that the common node combines Y1+ Y2+ Y3+ Y4 together according to a preset sequence to form combined information, the hash value of the combined information is calculated, and the calculated hash value is used as the true hash value H1 of the commodity K.
For the commodity L: the link information of the raw material link is Z1, the link information of the production link is Z2, the link information of the storage link is Z3, and the link information of the logistics link is Z4, so that the common node combines Z1+ Z2+ Z3+ Z4 to form combined information according to a preset sequence, calculates the hash value of the combined information, and uses the calculated hash value as the true hash value H2 of the commodity L.
Then, the agent node clusters the true hash value H1 of commodity K with the true hash value H2 of commodity L to form a hash list.
And thirdly, the agent node sends the hash list to the consensus node, so that the consensus node can be used for consensus verification of the hash list.
In some embodiments, when the agent node sends the hash list to the consensus node, the agent node performs a signature operation on the hash list by using its own private key to obtain a block signature, wherein a public key corresponding to the private key is broadcasted to the blockchain system. And secondly, the agent node packages the block signature and the hash list and sends new block data to the common identification node, when the common identification node verifies the new block data, the common identification node verifies the block signature by using a legal public key of the agent node, and if the block signature is legal, the agent node considers that the new block data is sent by the legal agent node. If the block signature is illegal, the new block data is considered to be sent by the illegal proxy node, so that the safety of the block chain data can be improved by adopting the mode.
When the consensus nodes verify that the new block data is sent by the legal agent node, the consensus nodes verify the new block data by adopting a Proof of equity (POS) algorithm or a Delegated Proof of equity (DPOS) algorithm. And after the new block data is verified, the common identification node completes other block information, wherein the other block information comprises a block signature, a time stamp and the like, packs the new block data and broadcasts the whole network.
In some embodiments, the commodity anti-counterfeiting tracing method based on the block chain is applied to a alliance chain, and when a stock authorization certification algorithm is adopted as a consensus mechanism, the stock proportion of the stock authorization certification algorithm is distributed according to the scale of unmanned stores of various operators. For example, each blockchain node of the federation chain is a server erected by each operator of an unmanned store, the size of the unmanned store including the total area of the unmanned store or the number of registered users, and the like. The unmanned stores of the operator A are the largest in scale, the percentage is 10%, the operator B is 6%, and the operator C is 3%. The.
Some common identification nodes are in failure or wrongness (do not sign and verify new blockchain data), and in order to ensure that the blockchain system can normally go out of blocks, other common identification nodes can do view updating to stop the common identification right of the failure or wrongness common identification nodes. Therefore, in some embodiments, in the process of consensus verification of new blockchain data by consensus nodes, when it is detected that the number of times of consensus verification failures is greater than a preset threshold, a consensus server group formed by the consensus nodes determines a malicious consensus node, where the malicious consensus node is a node that does not sign and verify the new blockchain data and causes the maximum number of times of consensus verification failures. The consensus server group consisting of the consensus nodes prohibits the malicious consensus nodes from participating in consensus verification, shares are redistributed to the rest consensus nodes, and new block chain data are subjected to consensus verification, for example, the consensus node A with the percentage of 10% is bad, so that the consensus server group stops the voting right of the consensus node A firstly, and then distributes the percentage of 10% of the consensus node A to the rest consensus nodes according to a preset rule, for example, the consensus nodes are distributed to the rest consensus nodes uniformly, or the consensus nodes are distributed to the rest nodes according to the working ages of the consensus nodes, and the distribution percentage is lower as the working ages are longer and the distribution percentage is higher and the working ages are shorter.
And thirdly, when the number of times of the failure of the consensus verification is detected to be less than the preset threshold value, the consensus server group continues to perform the consensus verification on the new block chain data.
In this way, it is ensured that the block chain system can smoothly go out of blocks.
S43, traversing the hash list to see whether a real hash value corresponding to the hash value to be verified exists;
s44, if yes, returning commodity verification success information to the client;
and S45, if not, returning commodity authentication failure information to the client.
