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.
The inventors of the present application have found, through long-term research: currently, commodity information is collected and used by each merchant individually from the production, transportation, distribution, retail sale, and distribution of the commodity to the consumer. Due to the lack of credible guarantee of the commodity information independently managed by each merchant, the possibility that the commodity information is maliciously kneaded and manufactured is easy to occur, the accuracy of a commodity information acquisition source cannot be ensured, and the credibility of the acquired commodity information is reduced. Moreover, due to the fact that trust among various merchants is separated, the commodity information is difficult to be shared in a trusted mode, once a certain commodity has a quality problem, a problem root cannot be found from the scattered commodity information quickly, processing time of the commodity problem is prolonged, and property loss of consumers and credit loss of the merchants are easily caused. To solve these problems, the present application proposes at least the following embodiments.
Referring to fig. 1, fig. 1 is a schematic structural diagram of an embodiment of a product information management system according to the present application. The management system 10 of the present embodiment may include a management platform 110 and a blockchain system 120. The management platform 110 is, for example, a person or thing or a collection thereof related to the full link of the commodity from the raw material acquisition to the final commodity to the consumer. The management platform 110 may collect commodity information corresponding to each link. The management platform 110 may further encrypt the commodity information and send the encrypted commodity information to the blockchain node 121 for distributed storage, so as to implement information interaction with the blockchain system 120.
In this embodiment, in the full link from the production to the sale of the goods, a plurality of transaction parties are often involved, for example, including a producer, a carrier, a distributor, a retailer, a manager, and the like, and these transaction parties may respectively configure corresponding management platforms 110 to respectively collect the respective goods information, thereby achieving flexibility of goods information collection. For example, the management platform 110 of the producer may be used to collect production information of goods, the management platform 110 of the carrier may be used to collect logistics information, the management platform 110 of the dealer may be used to collect sales information, and the like; after each management platform 110 collects the commodity information, it may send it to the corresponding blockchain node 121 for distributed storage.
In this embodiment, the commodity information may include information related to a full link from the raw material purchase to the commodity finally to the consumer. For example, the commodity information may include production information, logistics information, sales information, warranty information, and the like. The merchandise information may also include various types or formats of information such as paper documents or electronic data, etc. The management platform 110 may collect various kinds of commodity information, and may perform legal processing on the commodity information to satisfy corresponding rules. For example, the management platform 110 may collect paper documents of the commodities and electronize the paper documents, which is beneficial to better save information in the paper documents of the commodities, improve authenticity and integrity of the commodity information, and also can be used as a certification document of the commodities for subsequent checking of the commodities.
The management platform 110 may also interact with the blockchain system 120. For example, the management platform 110 may send the commodity information formed by processing the commodity by the transaction party to the blockchain node 121 in the blockchain system 120 for distributed storage. The management platform 110 may also obtain corresponding merchandise information through the blockchain system 120 for the transaction party to check the merchandise.
The management platform 110 is, for example, a computer, and can execute corresponding program instructions to collect commodity information or perform information interaction. Alternatively, the management platform 110 may also include a collection of multiple devices. For example, the management platform 110 may include a collection device, a processing device, a communication device, and the like for the commodity information, and the management platform 110 may collect the commodity information by using the corresponding collection device, process the commodity information by using the processing device, and send the commodity information to the block chain node 121 by using the communication device.
The blockchain system 120 of the present embodiment may include a plurality of blockchain nodes 121 for implementing distributed storage and sharing of commodity information. Blockchain node 121 may participate in endorsement, ordering, packing blocks, communication, accounting, etc. of the blockchain. For example, after receiving the commodity information sent by the management platform 110, the block chain nodes 121 may sort and pack the commodity information into blocks according to the corresponding rules of the block chain system 120, and then broadcast the blocks to the block chain network to implement distributed storage of the commodity information.
In this embodiment, the blockchain system 120 may be operated by a special organization or manager, and each transaction party may perform information interaction with the corresponding blockchain link point 121 through the management platform 110. Or, the transaction party may also operate one or more block chain nodes 121, and after acquiring the commodity information, the management platform 110 may send the commodity information to the block chain node 121 of the corresponding transaction party, and the block chain node 121 broadcasts the commodity information to the block chain network, so that the storage efficiency of the commodity information can be effectively improved.
In some embodiments, the blockchain node 121 of the blockchain system 120 may also include a production node. The production node is, for example, a blockchain link point 121 operated by the commodity producer, and can be used for realizing interaction between the commodity producer and the blockchain network. The production node can collect production batch information of the commodity and generate the identity of the commodity based on the production batch information. The identification may be used to distinguish between each batch of goods. The production node may also register the identity of the commodity on the blockchain, for example, broadcast the identity of the commodity to the blockchain network, so that other blockchain nodes 121 may store the identity after verifying that the identity is valid.
In some embodiments, the management platform 110 itself may also participate in the blockchain network as a blockchain node 121. The management platform 110 may broadcast the collected merchandise information directly to the blockchain network for distributed storage.

Referring to fig. 2, fig. 2 is a schematic flowchart of a block chain-based merchandise information management method according to a first embodiment of the present application. The embodiment comprises the following steps:
s101: the management platform electronizes the paper files of the commodities to form commodity data.
In this embodiment, the paper document of the commodity includes, for example, a raw material purchase document or contract of the commodity, a production record, a logistics transportation document, a transportation order, a warehouse receipt, a sales document, an identification document of a transaction party, other paper bills, and the like. The management platform can form the paper documents into commodity data in an electronic mode, so that the paper documents of commodities can be saved and managed conveniently, and the formed commodity data is more real and complete.
The merchandise data may include data of various types or formats, including, for example, picture, audio, video, electronic document, and the like. The management platform can be provided with a corresponding electronization unit for electronizing the paper files to form commodity data of corresponding types or formats. For example, in some embodiments, the management platform may include a scanning unit, and the management platform may also scan paper documents with the scanning unit to form merchandise data.
The scanning unit comprises a camera, for example, and the management platform can use the camera to shoot paper files of the commodities to form commodity data in a picture or video format. Or, the scanning unit may also include a scanner, and the management platform may scan the paper document of the commodity by using the scanner to form commodity data of a corresponding electronic document type.
In some embodiments, the management platform may also integrate merchandise data formed from multiple paper documents of the merchandise. For example, the management platform may integrate a plurality of electronic documents obtained by scanning a plurality of paper documents of a commodity into one electronic document in a corresponding order, which is beneficial to saving the storage space of commodity data and facilitating the orderly management of the commodity data of the plurality of commodities.
S102: the management platform encrypts at least the merchandise data to form encrypted electronic data.
In this embodiment, the management platform may encrypt the commodity data by using a corresponding encryption algorithm, thereby forming encrypted electronic data. The management platform can conceal the original information of the commodity data by encrypting the commodity data, and plays a role in protecting the safety and privacy of the commodity data. The management platform can encrypt the commodity data and can encrypt other data related to the commodity to form encrypted electronic data, so that the commodity information can be more complete.
The management platform can encrypt the commodity data in a plurality of encryption modes. For example, the management platform can encrypt the commodity data to form encrypted electronic data by adopting a symmetric encryption method, and the encryption operation is simple and quick and has high safety. Alternatively, the management platform may encrypt the commodity data by using an asymmetric encryption method. For example, the management platform may encrypt the commodity data by using a private key to form encrypted electronic data, and when another party needs to acquire content in the encrypted electronic data, the encrypted electronic data may be decrypted by using an authorized public key, so that the encryption key of the management platform may be effectively protected, and the security may be improved.
In some embodiments, the management platform may encrypt the commodity data to form a corresponding hash value by using a hash encryption method. The management platform can send the hash value as encrypted electronic data to the blockchain node for distributed storage, so that the storage space occupied by the blockchain account book data can be effectively saved, the accounting efficiency of the blockchain node is improved, and meanwhile, commodity data cannot be tampered.
In some embodiments, when encrypting the commodity data, the management platform may further process the commodity data in advance to extract the key commodity data, and then perform distributed storage on the key commodity data, so that the key commodity data may not be tampered, the storage space of the block chain node may be saved, and the efficiency is higher. For example, S102 may further include: the management platform screens and converts the commodity data to form key commodity data; the key good data is encrypted to form encrypted electronic data.
The management platform can screen the commodity data according to corresponding rules. For example, the management platform may filter the commodity data to filter out repeated data, wrong data, or incomplete data in the commodity data, or filter out data with incorrect type or format in the commodity data to improve the effectiveness and accuracy of the commodity data.
In this embodiment, the management platform may also select important data to be linked and stored according to the function of the corresponding transaction party. For example, the management platform of the manufacturer can screen the commodity data, and extract the relevant commodity data such as the identity certification document of the production party, the production batch number of the commodity, the production time, the production equipment information and the like; the management platform of the carrier can screen the commodity data and extract the carrier identification data, the logistics personnel identification data, the logistics transportation bill, the transportation route and other related commodity data. The management platform can extract important commodity data for distributed storage by screening the commodity data, so that the validity of the commodity information can be ensured, and the simplified commodity data is favorable for the high efficiency of subsequent commodity information query.
The management platform screens the commodity data, can select accurate and effective commodity data, and then can perform format conversion on scattered commodity data so as to integrate the commodity data into a required data format. For example, the commodity data screened out by the management platform has two types of picture formats and video formats, and the management platform converts the commodity data in the picture format into the data in the corresponding video format through format conversion and integrates the data into a whole to form the key commodity data, so that the ordered management of the commodity data is facilitated, and the calculation amount of the commodity data when the block chain nodes store the commodity data in a distributed manner can be saved.
In this embodiment, the management platform may further store the complete commodity data, for example, the complete commodity data is stored in a local storage or a cloud storage of the management platform. A commodity information sharing database can be established among the management platforms, and each management platform can also store the acquired complete commodity data in the sharing database, so that traders in each link of commodity circulation can inquire and verify the commodity information.
S103: the management platform sends the encrypted electronic data to the blockchain node.
In this embodiment, the management platform may send the encrypted electronic data to the blockchain node for distributed storage. For example, the management platform may send the encrypted electronic data to a sorting node in the blockchain system, and the encrypted electronic data is sorted and packaged by the sorting node and then broadcast to the blockchain network for distributed storage. Alternatively, the management platform may send the encrypted electronic data to the corresponding block chain node operated by the transaction party, and the block chain node of the transaction party broadcasts the encrypted electronic data to the block chain network.
In this embodiment, when the management platform sends the encrypted electronic data to the blockchain node, the private key can be used to sign the encrypted electronic data, so that the identity validity of the blockchain node verification management platform can be facilitated, and the identity of the corresponding transaction party can be conveniently determined by the identity of the management platform when the commodity information is verified.
In some embodiments, the management platform may further perform hash encryption on the commodity data to form a corresponding hash value, and then send the hash value to the block chain node for distributed storage. The block chain nodes store the hash values in the block chains, so that a large amount of commodity data does not need to be stored, the storage space of the block chain nodes is saved, and once the commodity data is modified, the hash values formed by encrypting the commodity data are changed and cannot be matched with the hash values stored in the block chains, so that the irreparable modification of the commodity data can be ensured.
S104: the block link points distributively store the encrypted electronic data.
In this embodiment, after receiving the encrypted electronic data from the management platform, the blockchain nodes may sort and pack the encrypted electronic data into blocks, and then broadcast the blocks to the blockchain network for distributed storage, and the nodes in the blockchain system may synchronize the latest blocks to store complete blockchain data.
In some embodiments, the management platform operates a blockchain node corresponding to the transaction party, and the management platform may further send the encrypted electronic data to a corresponding blockchain node of the transaction party, and the blockchain node broadcasts the encrypted electronic data to a blockchain network for sorting and packaging. The transaction party's blockchain link points may also synchronize new blocks to preserve complete blockchain data. Or, when the management platform itself serves as a blockchain node, the encrypted electronic data may also be directly broadcast to a blockchain network for distributed storage, and a complete blockchain may be synchronized to facilitate subsequent query of the commodity information.
In some embodiments, the blockchain system may provide a special blockchain link point, such as a sorting node, for sorting and packaging the commodity information into blocks. After receiving the encrypted electronic data, the sorting node can sort and pack the encrypted electronic data into blocks according to the rule of the block chain system, and then broadcast the new blocks to the block chain network for distributed storage. The sequencing nodes can also be packed in sequence without depending on the calculation for taking the corresponding accounting right, so that the calculation power of the sequencing nodes can be effectively saved, and the block packing efficiency is improved.
The block link points store the encrypted electronic data in a distributed manner, so that the encrypted electronic data cannot be tampered, and the security and the reliability of corresponding commodity information can be protected. The encrypted electronic data stored on the blockchain may also be used for a transacting party's inquiry for merchandise information. For example, a transaction party of a commodity may request commodity information of the commodity from any blockchain node or an information query channel provided by the blockchain system, so as to be used for verification of the commodity information or authentication or anti-counterfeiting of the commodity.
The management platform of the embodiment electronizes the paper documents of the commodities to form commodity data, can effectively store the information of the paper documents in each link of commodity circulation, and is favorable for improving the authenticity, accuracy and integrity of commodity information; the commodity information is encrypted and then sent to the block chain nodes for distributed storage, so that the commodity information is protected from being tampered, privacy of the commodity information can be protected after the commodity information is encrypted and safety of the commodity information is effectively improved.
In this embodiment, the sequence of steps S101 to S104 is the description sequence in this embodiment, and is not limited to the sequence of the block chain-based product information management method in the execution process in this embodiment, and on the premise that the method can be implemented, some steps may be executed simultaneously or individually by exchanging the sequence.
Referring to fig. 3, fig. 3 is a flowchart illustrating a commodity information management method based on a block chain according to a second embodiment of the present application. This embodiment is further described on the basis of the first embodiment of the block chain-based product information management method of the present application, and the same steps as those in the first embodiment of the block chain-based product information management method of the present application are not described herein again. The embodiment comprises the following steps:
s201: the management platform electronizes the paper files of the commodities to form commodity data.
S202: the management platform acquires the identity of the commodity.
The identification of the goods may be used to identify each good individually or in batches to distinguish it from other goods. The identity may include a string of characters, a graphic code, and the like. The management platform can obtain the identity of the commodity by identifying the identity imprinted on the outer package of the commodity; or the management platform can also receive the identity transmitted by other equipment or receive the input identity through the man-machine interaction interface.
In this embodiment, the identity of the commodity may be configured by the producer of the commodity based on the relevant production information of the commodity. For example, the producer may generate an identification of the good based on production lot information for the good. The production lot information of the commodity includes, for example, information on a production side, a production lot number, production time, production amount, production equipment information, production responsibility information, and the like. The producer may configure the identity of the goods based on some or all of the information therein. For example, in a specific embodiment, the producer of the commodity in the production lot information is XX, the production time is 2020, 4 months and 1 day, and the corresponding production equipment number is E07, the producer can generate the commodity id XXE0720200401 0200720401. When each piece of goods in the same batch of goods needs to be identified separately, the production party can also configure a corresponding number of each good, and generate an identity of the goods based on the production batch information of the goods and the corresponding number, so that each piece of goods in the same batch of goods can be distinguished. For example, in the above specific embodiment, the batch of products has 100 products, and one product has the product number of 007, the manufacturer can configure the product with the product identification of XXE 0720200401007. The production side is favorable for distinguishing each commodity by configuring the serial number for each commodity in the same batch of commodities, the identification generated based on the production batch information and the serial number of the commodity can be used for distinguishing each commodity, the identification of the commodities in the same batch is related, the related commodities in the same batch can be conveniently determined in time when the commodities have problems, and the quality control of the commodities is favorable.
Optionally, the identity of the commodity may also be generated by encrypting the production batch information of the commodity by the producer. For example, the producer may encrypt the production batch information of the commodity to generate a character string with a specific length, where the character strings formed by encrypting different production batch information are different, and the character string may be used as the identification of the commodity. Therefore, the privacy of the commodity production batch information can be effectively protected, and commodities of each batch can be effectively distinguished. The producer can also combine the character string formed by encrypting the production batch information and the serial number of the commodity as the identity of the commodity so as to effectively distinguish each commodity.
In some embodiments, the article may be further configured with an identity tag for obtaining an identity of the article through the identity tag.

The RFID label can be a passive label, and when the RFID label of the commodity enters a magnetic field emitted by the RFID read-write unit, the RFID label can send the stored identity mark or other related information to the RFID read-write unit by virtue of energy obtained by induced current. The RFID tag may also be an active tag, which may automatically send the RFID reader/writer unit the identification or other relevant information stored therein.
In some embodiments, the producer of the goods configures the identity of the goods, and may also register the identity of the goods with the blockchain. For example, the producer may send the identity of the commodity to the blockchain link point in the blockchain system, and after the identity is correctly stored in a distributed manner, it is indicated that the identity of the commodity is valid. After the management platform obtains the identity of the commodity, the management platform can also obtain the identity list registered on the block chain, and verify the validity of the identity of the commodity, so that the possibility of commodity counterfeiting can be effectively reduced.
For example, the management platform may match the identifier with an identifier in an identifier list on the blockchain, and query whether the identifier is correctly registered on the blockchain. The management platform can further verify whether the identity of the commodity is cancelled or not so as to verify whether the identity is valid or not. If the management platform verifies that the identity of the commodity is correct and valid, the following steps can be continuously executed; if the identity is not verified or is invalid by the management platform, the following steps can be refused to be executed.
S203: the management platform encrypts at least the merchandise data to form encrypted electronic data.
In this embodiment, when encrypting the commodity data, the management platform may obtain other related data of the commodity and encrypt the data together to form encrypted electronic data. For example, the article may be configured with an RFID tag, and the management platform may perform read and write operations on the RFID tag using an RFID read/write unit. The management platform can also be provided with a positioning unit, and after the RFID reading and writing unit is used for reading the RFID label of the commodity, the management platform can also be positioned by the positioning unit so as to obtain the current position information of the commodity.

The management platform can also encrypt the temperature data, the humidity data and the commodity data to form encrypted electronic data, and send the encrypted electronic data to the block chain nodes for distributed storage, so that the environmental information in the commodity production or transportation process can be effectively stored.
The management platform can also read the temperature data and the humidity data when the RFID reading and writing unit is used for reading the identity of the commodity in the RFID label, so that the operation steps of the management platform can be saved. The management platform can also update the temperature data and the humidity data to a shared database of commodity information, so that other transaction parties can conveniently inquire the temperature data and the humidity data. Optionally, the environment detection module of the RFID tag may also measure the temperature and humidity of the environment where the commodity is located at preset intervals, and store the temperature data and humidity data measured for many times, so as to facilitate monitoring the environmental change of the commodity during the process of multi-turn or long-distance transportation, so as to determine the cause of the problem in time when the quality of the commodity is problematic due to the change of the environment, and facilitate the transaction party to determine the responsible party of the problem.
Optionally, the management platform may further read the identification, the temperature data, and the humidity data of the commodity in the RFID tag by using the RFID reading/writing unit, and automatically trigger the positioning unit to perform positioning to obtain the current position information of the commodity. The management platform may encrypt the temperature data, the humidity data, the current location information, and the merchandise data to form encrypted electronic data.
In some embodiments, the management platform may also verify the merchandise data and other data to determine if the merchandise is satisfactory before encrypting the merchandise data and other related data to form encrypted electronic data. For example, the management platform may determine whether the environmental data and the quality data of the product satisfy a predetermined product requirement, so as to determine whether the product has a quality failure or an illegal operation.
The preset commodity requirements can be used for standardizing the rules of management and operation of each transaction party on commodities in the commodity circulation process. The preset commodity requirements comprise, for example, relevant rules of environmental information and quality information of each link of commodity production, transportation, storage and sale. For example, in the commodity production process, the production environment, raw materials, performance detection modes and the like of commodities can be specified in preset commodity requirements; for another example, in the process of transporting commodities, the transportation duration, transportation mode, transportation environment, commodity package and the like of the commodities can be specified in the preset commodity requirements.
The management platform determines whether the environmental information and the quality information of the commodity meet the preset commodity requirement, for example, by extracting corresponding data from the commodity data and other related data, and comparing the extracted data with corresponding rules in the preset commodity requirement. For example, the temperature range of the preset commodity requirement during commodity transportation is 0-10 ℃, the temperature data of the management platform in the commodity transportation process is 7 ℃ after the RFID label of the commodity is scanned, and the management platform determines that the temperature of the commodity during transportation meets the preset commodity requirement.

Before encrypting the commodity data and other related data to form encrypted electronic data, the current management platform can also verify whether the historical information of the commodities stored on the block chain meets the preset commodity requirement so as to determine whether the commodities have unqualified quality or illegal operation and the like.
The management platform can request part or all of the historical information corresponding to the identification from the block chain nodes by using the identification of the commodity, and checks the historical information of the commodity after decryption to verify the quality of the commodity or the authenticity and validity of the commodity information, so that the management platform can be favorable for managing and controlling the quality of the commodity, is favorable for finding the root of the problem and determining the responsible party of the problem when the quality problem or illegal operation occurs in the commodity, and effectively reduces the loss of a transaction party.
The management platform can encrypt the commodity data and other related data to form encrypted electronic data after verifying that the commodity data and other related data meet the preset commodity requirements. If the management platform verifies that the data which do not meet the requirement of the preset commodity exist, the management platform can also send out a commodity unqualified message so that a trading party can quickly check the commodity and stop loss in time.

Specifically, the management platform can associate the encrypted electronic data with the identity of the commodity and then send the encrypted electronic data to the block chain nodes for sequencing and packaging, so that the ordered management and efficient query of the stored commodity information by the block chain nodes are facilitated.
When the management platform sends the associated encrypted electronic data and the identity identifier to the block chain nodes, the encrypted electronic data can be signed by using the private key, so that the identity validity of the management platform can be verified by using the block chain nodes, and the identity of the corresponding transaction party can be conveniently determined by the identity of the management platform when the commodity information is subsequently checked.
S205: the block link points distributively store the encrypted electronic data.
In this embodiment, after the block chain node receives the encrypted electronic data from the management platform, the encrypted electronic data and other information associated with the corresponding identifier stored in the block chain may be stored in association according to the identifier associated with the encrypted electronic data, so as to facilitate subsequent quick inspection of the information related to the commodity stored in the block chain.
In this embodiment, the management platform associates the encrypted electronic data with the identity, and after the block link point stores the encrypted electronic data in a distributed manner, the associated encrypted electronic data may be queried by using the identity of the commodity. The encrypted electronic data stored on the blockchain may also be used for a transacting party's inquiry for merchandise information. For example, a transaction party of a commodity may obtain an identification of the commodity by scanning an RFID tag of the commodity, and request to obtain encrypted electronic data corresponding to the identification stored in the blockchain from a blockchain link point or a corresponding information query channel by using the identification. Or the transaction party can participate in the blockchain network to serve as a blockchain with synchronous and complete blockchain nodes, and after acquiring the identity of the commodity, the transaction party can directly inquire corresponding encrypted electronic data from the blockchain stored by the transaction party. The transaction part can also decrypt the encrypted electronic data by using the corresponding secret key after acquiring the encrypted electronic data so as to acquire corresponding commodity data or other related data.
In some embodiments, stored in the blockchain is a hash value obtained by hash-encrypting the commodity data and other related data, and the hash value can also be used for verifying the authenticity and accuracy of the commodity information. For example, the transaction party may obtain the hash value of the commodity through the block chain node or the corresponding information query channel by using the commodity identifier, and determine the management platform corresponding to the encrypted electronic data by using the signature corresponding to the encrypted electronic data. The management platform can provide commodity data or other related data corresponding to the encrypted electronic data to the transaction party after verifying that the identity and the commodity identification of the transaction party are correct.
