Description

Seafood history management and statistical analysis system using blockchain {system for seafood history management and statistical analysis using blockchain}

The present invention relates to a marine product history management and statistical analysis system using a block chain, and more particularly, to a marine product history management and statistical analysis system using a block chain that improves information reliability and security by preventing fabrication and forgery of the origin of aquatic products in advance.

Since Bitcoin, the first blockchain-based application, was developed in 2009, blockchain has been applied to various fields, such as cloud storage services and block-chain computing services, as well as electronic money systems such as Bitcoin.

Here, Bitcoin is electronic money issued, stored, and distributed on a distributed network rather than a centralized organization such as a government or bank. Bitcoin was first issued in 2009 and has maintained its value as a currency without a centralized institution until now, and is rapidly increasing in terms of the number of users and transaction volume.

There is a block chain technology behind maintaining the monetary value of these bitcoins. At this time, blockchain is a technology that maintains security and integrity in a decentralized network environment without a centralized server, and based on these strengths, various computing data can be shared, and it has begun to be applied to systems other than electronic money.

For example, there is a cloud storage system using a block chain that issues its own coin to a storage provider, uses the disk space of another computer, and maintains reliability through division verification.

As another example, Ethereum is a platform that can register and run applications that perform smart contracts for electronic money. While Bitcoin simply provides electronic money remittance, Ethereum provides transactions based on contracts.

However, blockchain has an inefficient operating structure that wastes computing resources. Specifically, in the case of Bitcoin, it takes as much time as possible to verify the integrity of transaction transactions, and each participating node must store a 30Gbyte ledger. In addition, in order to approve a transaction, all nodes must verify the transaction through the ledger and approve the transaction based on the verification result. That is, all nodes participating in the blockchain must store all the same ledgers and perform all the same verification tasks. For these reasons, blockchain is very inefficient in terms of resources from the perspective of the entire network.

As mentioned, blockchain is the core technology used in Bitcoin for decentralized currency management. Blockchain maintains the integrity of transactions by making it impossible for any user to forge data without a central management authority.

In addition, in order to maintain the integrity of the blockchain, all participating nodes participating in the blockchain network store transaction details (books), and newly generated transaction transactions are inspected through the stored ledger.

For example, even if one participating node manipulates a transaction and conducts a double payment, all other nodes verify whether the double payment is made and reject the agreement, thereby rejecting the transaction approval. Therefore, data manipulation does not occur unless more than 51% of all nodes agree falsely.

On the other hand, research and development on aquatic product traceability management methods are being conducted to prevent fabrication and falsification of the origin of aquatic products.

However, research is being conducted to secure security that can prevent fabrication and falsification of the origin of aquatic products in the production, processing, distribution, and sales stages of aquatic products, but development is insufficient.

Korean Patent Registration No. 10-0704950

In order to solve the above problems, the present invention is to provide a marine product history management and statistical analysis system using a block chain in which manipulation of origin and forgery of aquatic products are prevented in advance and information reliability and security are improved.

In order to solve the above problems, the present invention is a production history input module in which producer information that produced aquatic products is input and production history information about aquatic products is input; A distribution history input module in which distributor information for distributing aquatic products is input and distribution history information for aquatic products is input; A sales history input module in which seller information for selling aquatic products is input and sales history information for aquatic products is input; A web server that is individually connected to the production history input module, the distribution history input module, and the sales history input module through an Internet network, stores a blockchainized database, and manages a key ID for linking information for the blockchain; A plurality of distributed storage units that are individually connected to the web server through an Internet network and store a block-chained database for the producer information, production history information, distributor information, distribution history information, seller information, and sales history information, respectively; A marine product history storage unit that is communicatively connected to the web server and stores databases of the producer information, the production history information, the distributor information, the distribution history information, the seller information, and the sales history information; And a user terminal including a buyer terminal and a seller terminal that are communicatively connected to the web server through an Internet network and display a block-chained database for the producer information, the production history information, the distributor information, the distribution history information, the seller information, and the sales history information, wherein the aquatic product history storage unit collects and stores logs generated when the user terminal communicates with the web server, stores statistics on each data stored in the aquatic product history storage unit, and is communicatively connected to the aquatic product history storage unit. Further comprising a statistics generator for generating a graph and transmitting it to the user terminal, wherein the statistics generator extracts the production history information, the distribution history information, and the sales history information from the aquatic product history storage unit and connects them to each other to generate route mapping data in which a distribution route for each aquatic product is block-chained and mapped, and the statistics generator extracts the producer information, the distributor information, and the seller information from the aquatic product history storage unit to create a block chained personal log for each producer, distributor, and seller. The production history input module includes a first identification display unit provided as a beacon to input the producer information including data on aquaculture decoration identification number, farm manager, and farm address, and an identification input unit provided as an RFID tag and attached to the aquatic product to input the production history information including data on the history number, object identification number, country of origin, date of birth, registration date, expiration date, and quarantine information of each aquatic product, and the user terminal includes the identification input unit An identification recognition unit provided as an RFID reader so that the input unit is recognized, and the aquatic product history storage unit further stores location information data for a buyer's location set as an area within a predetermined radius centered on the purchaser terminal, The location information data is updated and stored in the aquatic product history storage unit in real time through the Internet network and the web server, and in the seller information, sales information data for an area within a predetermined radius range centering on the location where aquatic products are sold is stored, Includes a transaction recommendation unit that is communicatively connected to the aquatic product history storage unit and compares the location information data and the sales location information data, wherein the transaction recommendation unit generates transaction recommendation data for a seller when the location information data and the sales location information data overlap with each other, transmits it to the buyer terminal, measures the capacity of the database encoded with a preset classification code and stored in the aquatic product history storage unit, and selectively controls the measured capacity to increase or decrease. Classification codes for major classifications classified by species, classification codes for intermediate classifications, and data for each classification code for subclasses are allocated to a byte space of a predetermined first capacity, and the allocation control unit controls to reallocate the byte space to a second capacity equal to or greater than the first capacity when any one of the data for each classification code allocated to the byte space of the first capacity exceeds the first capacity.

Through the above solution, the present invention provides the following effects.

First, the history information database for aquatic products entered through each history input module of the production place, collection place, processing place, and sales place is blockchainized, and the web server manages the key ID for information linkage for the block chain. Since it provides a platform that can search for highly reliable history information that is prevented from forgery and alteration, information reliability and security can be significantly improved.

Second, the statistics generation unit extracts and connects producer information, production history information, distributor information, distribution history information, seller information, and sales history information from the aquatic product history storage unit, and the distribution route for each aquatic product is blockchainized and mapped. Since path mapping data and human statistical data are generated, users can easily search data that is block-chained and forgery and falsification can be prevented, thereby improving reliability and ease of use.

Third, when the transaction recommendation unit matches and overlaps the location information data set to the area within the radius of the purchaser terminal and the sales location information data for the area within the radius of the location where the seafood is sold, transaction recommendation data for the seller is generated and transmitted to the buyer terminal, so that you can receive highly reliable aquatic products with history forgery and falsification prevented.

Fourth, data for each classification code for each major category, middle category, and small category for each fish species is allocated to a byte space of a predetermined first capacity, and if any one of the data for each classification code exceeds the first capacity, the byte space is reallocated to a second capacity equal to or greater than the first capacity, so that the ease of product identification can be remarkably improved even when data is scaled and increased.

Fifth, the blockchainized database for each history information is distributed and stored in a distributed storage unit provided as a storage device connected to the web server through individual communication with the web server, so that even if one participating node changes the history information, all other nodes verify the manipulation and reject the agreement, so the change approval is rejected, so security can be significantly improved.

Here, the sales history information may be further stored in the identification input unit 10b through the sales history input module 30 .

In addition, the blockchainized database for the sales history information may be stored in a distributed storage unit provided as a storage device by being communicatively connected to the web server 40 through an internet network.

Meanwhile, the web server 40 is individually connected to the distribution history input module 20 and the sales history input module 30 including the production history input module 10, the collection history input module, and the processing history input module through the Internet network 1, and the producer information, the production history information, the distributor information, the distribution history information, the access history information, the auction history information, the processing history information, the seller information, and the sales history information. Each database for each database is stored, and it is preferable to store a block chained database for each database and to manage a key ID for information linkage for the block chain.

Further, it is preferable that the production history input module 10, the distribution history input module 20, and the sales history input module 30 are individually connected to the web server 40 through the Internet network 1.

In addition, the aquatic product history management system 100 using the blockchain is connected to the web server 40 and the Internet network 1 by individual communication, and the producer information, the production history information, the distributor information, The distribution history information, The seller information and the sales history information.

In detail, the distributed storage unit preferably includes the production site distributed storage unit, the collection site distributed storage unit, the processing site distributed storage unit, and the sales site distributed storage unit. Here, it is preferable that the distributed storage unit is connected to the web server 40 through the Internet network 1, and a blockchainized database for the producer information and the production history information is distributed and stored. In addition, it is preferable that the collection site distributed storage unit communicates with the web server 40 through the Internet network 1 and stores a blockchainized database for the access history information and the auction history information. In addition, it is preferable that the processing area distributed storage unit communicates with the web server 40 through the Internet network 1 and stores a blockchainized database for the processing history information in a distributed manner. In addition, it is preferable that the distributed storage unit is connected to the web server 40 through the Internet network 1, and a blockchainized database for the sales history information is distributed and stored. At this time, the web server 40 may perform interlocking of the production site distributed storage unit, the collection site distributed storage unit, the processing site distributed storage unit, and the sales site distributed storage unit with the blockchain database.

To this end, it is preferable that the web server 40 is provided so that an individual server for blockchain manages the web server 40 and the distributed storage unit and manages a key ID for information linkage for linkage. In addition, the aquatic product history management and statistical analysis system 100 using the blockchain preferably applies the distributed server management technology using blockchain security while providing the blockchain technology. In addition, the web server 40 is constructed by applying database encryption, hacking prevention, and database protection technology even in the application of security and data management methods, and can perform database encryption and occasional destruction by grafting a new system.

Here, a blockchainized database for the producer information, the production history information, the distributor information, the distribution history information, the access history information, the auction history information, the processing history information, the seller information, and the sales history information may be stored in the web server 40 and the distributed storage unit. At this time, the web server 40 may include a block generator, and the block generator may generate a plurality of blocks by encrypting and block-chaining each data of the producer information, the production history information, the distributor information, the distribution history information, the access history information, the auction history information, the processing history information, the seller information, and the sales history information. In addition, the web server 40 may store key values and sequence values set for encryption, and may store each data and blocks generated through the block generator.

In addition, the block is generated in plurality, including data generated for each data to which a key value and sequence value set for encryption are assigned, and is encrypted data and block chained through a hash function such as SHA-256. It is preferable. Here, SHA (Secure Hash Algorithm) is a standard hash algorithm announced by the National Institute of Standards and Technology (NIST) and is most widely used worldwide in the overall software market. SHA-1 and SHA-2 series are currently mainly used, and SHA-2 is divided into SHA-224, SHA-256, SHA-384, and SHA-512 in detail, and SHA-256 is the most used. And, SHA-256 is composed of 256 bits and returns a 64-character string. For example, the string "contract" can be converted into 64 digit data such as "875C2FD188350...1877005365BA2" through SHA-256.

In addition, the block includes a header and a body, and in the header, a hash value of an adjacent block for forgery prevention, a block version, a Merkle Root, and a nonce value are stored. At this time, the hash function means a function that changes any data having a certain length into certain data of a certain length, and the block means a space in which data on transaction records are collected to form a tree structure.

These blocks are created one by one at predetermined time intervals and spread throughout the network through the Internet network 1, and each block is chained and connected to each other to prove the integrity of the n-1th block through the hash tree structure. For example, since the hash value identical to that of the n-1 block exists in the header of the n-th block, it can be proved that the n-1 block has not been tampered with.

Here, the aquatic product history management and statistical analysis system 100 using the blockchain does not require the issuance of coins and requires fast performance, so it requires the construction of a permissioned blockchain, and is open to the outside like a public blockchain. Because it is not a structure in which anyone can participate as a member of a node, it is possible to configure a node responsible for storing and sharing blockchain ledgers.

Meanwhile, the web server 40 preferably includes a client node, an agreement node, a peer node, and an authentication node. It is preferable to understand that the client node, the agreement node, the peer node, and the authentication node are provided as an architectural configuration. In detail, the client node is preferably provided to generate a transaction on behalf of the user terminal 60, call chaincode execution, request transaction assurance, collect transaction assurance responses, and generate transaction proposals. And, it is preferable that the agreement node is provided to receive the transaction proposal generated by the client node.

In addition, the peer node includes a ledger for storing transaction information to maintain a blockchain and a state store for storing state information according to transaction execution results, and receives a transaction generated from the client node and confirms the transaction, Orders transactions proposed by the client node according to a consensus algorithm, receives them from the peer node, and receives transaction and state update information in the form of a block from the consensus node. In detail, the client node can invoke chaincode execution by creating a transaction on behalf of the user terminal 10 corresponding to the user. That is, the client node may request a transaction guarantee and collect a transaction assurance response by generating a transaction and submitting the transaction to an endorsing peer node of the peer node.

Then, the client node that has collected the transaction assurance response generates a transaction-proposal and delivers it to the consensus node. Then, the peer node not only commits the transaction, but also maintains the block chain by being composed of a ledger that stores transaction information and a state store that stores state information according to transaction execution results.

Also, the peer node receives transaction and state update information in the form of a block from the consensus node. Here, some of the peer nodes constituting the peer node additionally serve as endorsing peers, and these endorsing nodes can execute the corresponding chaincode and guarantee the result according to the endorsing request of the client. The endorsement node and endorsement method are determined by the endorsement policy associated with that chaincode, which can be written along with the chaincode and co-located when the chaincode is deployed on the blockchain.

And, the consensus node is provided to sequence the transactions proposed by the client node according to a consensus algorithm and safely deliver them to the peer node. Here, the client node transmits a message including a transaction to the consensus node through a channel, and the agreement node orders the transaction messages and delivers them to all peer nodes connected to the channel. Accordingly, it is possible to provide an atomic broadcast service that guarantees that transaction messages delivered to each peer node are safely delivered in the same order.

On the other hand, the authentication node is preferably provided to issue credentials indicating authority for network access after verifying the identity of the node accessing the network, and individually issue a key ID for information linkage for the block chain. At this time, the authentication node may issue a public key certificate suitable for a service and a corresponding private key as credentials through a certification authority based on a public key infrastructure (PKI).

Accordingly, the web server 40 can perform quick data lookup through the construction of an index database and a state database for a blockchain database. That is, the web server 40 manages the block number or hash value in the database, and when searching for related data, it is possible to search the block using the block chain index.

In addition, the web server 40 can quickly retrieve transaction details by searching only the corresponding block by using the block number or hash value managed separately through the index database, and configures the state database to manage the current state data of the ledger and manage the latest values of all keys included in the transaction log. In addition, the web server 40 can manage keys by range, use a composite key to search all assets owned by a specific entity, and update information on keys to the latest state at all times, so that the basic status can be confirmed without direct inquiry on the ledger.

Meanwhile, the web server 40 generates a registration certificate for authenticating registration of the user terminal 60, and generates a transaction certificate independently of the registration certificate, but the transaction certificate can be individually generated by the web server 40 whenever a transaction is requested from the previously registered user terminal 60 so as to block identification of the issuer, i.e., the registration certificate for each terminal, by hackers only with transaction details.

Through this, although there is one ECA for each participant registered on the web server 40, there may be several TCAs, and by minimizing the possibility of reasoning about the correlation between ECA and TCA, it is possible to issue a certificate usable by the TLS protocol, which is a secure communication protocol, by generating public and private keys necessary for identifying registered participants who establish network connections for identified participants.

In detail, the client node, the peer node, and the consensus node may be managed through the web server 40 as an authentication authority. That is, the web server 40 issues a certificate that certifies that the registered participant is correct through the Enrollment Certification Authority (ECA), and issues another transaction certificate (TCA) whenever a registered user posts a transaction so that the issuer of the registration certificate cannot be identified only with the transaction details. In addition, although there is one ECA for each participant registered on the web server 40, there may be several TCAs. By making it impossible to infer a correlation between ECA and TCA, a certificate usable by the TLS protocol, which is a secure communication protocol, can be issued by generating a public key and a private key necessary for verifying a registered participant establishing a network connection for a participant identified through TLS_CA.

In addition, when each peer node registers itself in the membership service on the blockchain network through TLS, the web server 40 undergoes certificate-based authentication through the TLS Handshake process, and if the certificate is invalid, the peer node can be controlled to prevent access to the membership service. Further, communication between the peer nodes is performed through TLS authentication, and for TLS-based communication, a certificate is required for each communication section, that is, a section between an authentication node, the peer node, and each peer node. Through this, the web server 40 generates a registration certificate for the user terminal 60, but independently generates a transaction certificate when a transaction is requested from the user terminal 60. By minimizing the possibility of inferring the correlation between the registration certificate and the transaction certificate, security can be remarkably improved.

On the other hand, the user terminal 60 is communicatively connected to the web server 40 through the Internet network 1, and includes a buyer terminal 61, a seller terminal 62, and a producer terminal 63 displaying a block chained database for the producer information, the production history information, the distributor information, the distribution history information, the access history information, the auction history information, the processing history information, the seller information, and the sales history information. It is desirable.

Also, the user terminal 60 preferably includes an identification recognition unit 60a provided as an RFID reader to recognize the identification input unit 10b. For example, the identification recognition unit 60a may be provided as an RFID reader and built into the purchaser terminal 61 provided as a smart phone. In addition, producers and sellers connect to the web server 40 through the Internet network 1 using the producer terminal 63 and the seller terminal 62 to access and manage aquatic products at the production site, collection site, and processing site. History management such as movement and object management can be easily performed. In addition, the purchaser approaches the identification unit 60a provided in the purchaser terminal 61 at the place of sale to the identification input unit 10b installed by attaching an RFID tag to one side of a fish species corresponding to mackerel or the like of 30 cm or more, and approaches the producer information, the production history information, the access history information, the auction history information, the processing history information, the seller information, The sales history information can be easily inquired.

On the other hand, the aquatic product history storage unit 50 is communicatively connected to the web server 40, and is preferably provided as a storage device for storing each database for the producer information, the production history information, the distributor information, the distribution history information, the access history information, the auction history information, the processing history information, the seller information, and the sales history information. The aquatic product history storage unit 50 is preferably provided to collect and store logs generated when the user terminal 60 communicates with the web server 40.

In addition, the aquatic product history management and statistical analysis system 100 using the blockchain is connected to the aquatic product history storage unit 50 and generates a statistical graph for each data stored in the aquatic product history storage unit 50. It is preferable to further include a statistics generating unit 70 for transmitting to the terminal 60.

Here, the statistics generating unit 70 extracts and connects the producer information, the production history information, the distributor information, the distribution history information, the entry and exit history information, the auction history information, the processing history information, the seller information, and the sales history information from the aquatic product history storage unit 50, and connecting them to each other to generate route mapping data in which the distribution route for each aquatic product is block chained and mapped. At this time, mapping means that each history information stored for aquatic products is extracted as map data stored in the aquatic product history storage unit 50 and a distribution route is created as a point, line, plane, etc. on the map data.

In addition, the statistics generator 70 extracts the producer information, the production history information, the distributor information, the distribution history information, the access history information, the auction history information, the processing history information, the seller information, and the sales history information from the aquatic product history storage unit 50 to generate block-chained personal statistical data for each producer, distributor, and seller.

And, the statistics generating unit 70 may transmit the generated route mapping data and the personal statistics data to the user terminal 60 through the web server 40 and the Internet network 1 . Through this, the user can easily query the data that is block-chained and forgery and falsification can be prevented, thereby improving reliability and ease of use.

For example, referring to FIG. 2, the user can use the blockchain-based aquatic product history management and statistical analysis system 100 on a web page where each database can be used, the initial screen / search process, login, personal screen, post-login / search, search results, and statistical analysis pages. You can be provided with a marine product history tracking function on each screen. At this time, the statistics generating unit 70 may be provided as an arithmetic processing device utilizing big data and machine learning, and the user may be provided with a history tracking function for which route the seafood is distributed, which fish species, and which company it is.

In addition, the statistics generating unit 70 needs to analyze multidimensional statistics such as origin, unstructured information, and distribution information through data mining in order to implement multidimensional statistical analysis information such as history tracking and production origin for aquatic products. Therefore, it is possible to implement detailed management of production, processing, distribution, and consumption history in detail by implementing detailed history management through the application of blockchain distributed storage technology. In addition, it includes block chain application contents for each stage of arrival, processing, storage, collection, and sale. Data generated at each process stage is managed through distributed storage, and when the corresponding data forms a pattern, it can be equipped to provide multi-dimensional statistical analysis information through big data analysis and mining technology.

Here, the statistics generating unit 70 can generate statistical reporting data through log analysis and e-commerce analysis as a multi-dimensional statistical analysis function. Statistical analysis data on distribution and sales companies can be created. In addition, the statistics generating unit 70 can provide a statistical information search function classified into each category such as by period and by fishery product, and a function that can search accurate statistical information by setting detailed search conditions for each category. In addition, the statistics generating unit 70 can convert the data to Excel so that the searched statistical information can be utilized to provide download and print functions, structure and manage the stored data, and provide useful market statistical information to aquatic product history-related companies and support organizations as a report. Furthermore, the statistics generating unit 70 may utilize stored data to reprocess information and provide related information to users.

On the other hand, the aquatic product history storage unit 50 further stores location information data for the location of the buyer set as an area within a preset radius around the purchaser terminal 61, and the seller information preferably stores sales location information data for an area set as an area within a preset radius around the location where aquatic products are sold. At this time, the location information data for the location of the purchaser set to an area within a predetermined radius around the purchaser terminal 61 is the aquatic product history storage unit 50 through the Internet network 1 and the web server 40. It can be updated and stored in real time. For example, an area within a preset radius range centered on the purchaser terminal 61 in the whereabouts information data, and an area within a preset radius range centered on a location where aquatic products are sold in the sales location information data may be set to 3 km, etc., but is not limited thereto. At this time, it is preferable to understand that the location where the seafood is sold is set as the center point of the location coordinates of the fish market, large mart, and the like.

In addition, the aquatic product history management and statistical analysis system 100 using the block chain is communicatively connected to the aquatic product history storage unit 50, compares the location information data and the sales location information data, and when matched, a transaction recommendation unit 80 for generating transaction recommendation data for a seller and transmitting it to the buyer terminal 61.

Here, the transaction recommendation unit 80 generates transaction recommendation data when the location information data and the sales location information data match and overlap each other, and transmits the data to the purchaser terminal 61 through the web server 40 and the Internet network 1. Also, the transaction recommendation unit 80 may not generate transaction recommendation data when the location information data and the sales location information data do not match and overlap each other.

Therefore, when the transaction recommendation unit 80 matches and overlaps the location information data set to the area within the radius range of the buyer terminal 61 and the sales location information data for the area within the radius range of the location where the marine product is sold, transaction recommendation data for the seller is generated and transmitted to the buyer terminal 61, so that the user can receive highly reliable marine products that are prevented from forgery or falsification of the history.

On the other hand, the aquatic product history management and statistical analysis system 100 using the blockchain measures the capacity of the database coded with a preset classification code and stored in the aquatic product history storage unit 50, and increases or decreases the measured capacity. It may further include an allocation control unit 90 that selectively controls to decrease.

Here, in the aquatic product history storage unit 50, data for a classification code for a major classification, a classification code for a middle classification, and a classification code for a subclass classified by fish species of aquatic products may be allocated to a byte space of a predetermined first capacity.

For example, each data for each classification code for a major classification, a classification code for a middle classification, and a classification code for a subclass classified by fish species of aquatic products is a two-digit number between "01" and "99", respectively. It can be allocated to the byte space of the first capacity.

At this time, the existing classification code may be assigned a total of six digit codes with two digit codes, respectively, for major classification, middle classification, and small classification. That is, if the 6-digit classification code for the ship supplies is known, the purchaser can easily check the corresponding history through the purchaser terminal 61.

Here, as the fish species are gradually added during the operation of the aquatic product history management and statistical analysis system 100 using the blockchain, the classification code for the major classification, the classification code for the middle classification, and each classification code for the sub classification may increase. A plurality of classification codes for the same classification name may be assigned randomly rather than assigned numbers adjacent to each other.

At this time, conventionally, when the number of classification codes exceeds "99", code values are temporarily assigned and used in other major classification codes. That is, if a code value is temporarily assigned and used in another major classification code, it becomes difficult to identify a product with a classification code, and there is a concern that a clear classification standard cannot be presented as a code.

Therefore, the allocation control unit 90 controls to reallocate the byte space to a second capacity equal to or greater than the first capacity, when any one of the data for each classification code allocated to the byte space of the first capacity exceeds the first capacity.

For example, when the allocation control unit 90 detects that the capacity of a classification code allocated to a byte space of a first capacity corresponding to a two-digit number between "01" and "99" exceeds the capacity, the allocation control unit 90 may reallocate a byte space to a second capacity equal to or greater than the first capacity between "001" and "999" for the classification code exceeding the capacity.

Through this, data for each classification code for each major category, middle category, and small category for each fish species is allocated to a byte space of a preset first capacity, and the allocation control unit 90 reallocates the byte space to a second capacity equal to or greater than the first capacity when any one of the data for each classification code exceeds the first capacity, so that the ease of product identification can be remarkably improved even when data is scaled and increased.

In this way, the producer information, the production history information, the distributor information, the distribution history information, the seller information, and the sales history information database for aquatic products input through the production history input module 10, the distribution history input module 20, and the sales history input module 30 are blockchainized, and the web server 40 manages the key ID for information linkage for blockchain to provide a platform that can search highly reliable history information that is prevented from forgery and alteration. Safety and security can be significantly improved.

In addition, the production history information, the entry and exit history information, the auction history information, and the processing history information generated in the production area, the collection area, and the processing area during the distribution process of the seafood product are additionally corrected and input to the identification input unit 10b attached as an RFID tag to the seafood product, and when the buyer approaches the identification recognition unit 60a provided as an RFID reader in the sales place to the identification input unit 10b within a preset radius, the buyer terminal 61 Through this, it is possible to easily inquire various history information on fishery products that are prevented from forgery and alteration, so the convenience of use can be remarkably improved.

Furthermore, the production history information, the access history information, the auction history information, and the processing history information are distributed and stored in a distributed storage unit including a production site distributed storage unit, a collection site distributed storage unit, a processing area distributed storage unit, and a sales area distributed storage unit provided as a storage device connected to the web server 40 by individual communication with the web server 40. Since it is rejected, security can be significantly improved.

In addition, transactions generated by client nodes are submitted, transactions are confirmed, and transactions proposed by client nodes are ordered and delivered to peer nodes, and transaction messages are safely transmitted in the same order through peer nodes that receive transaction and state update information in the form of blocks from consensus nodes. As such, it is possible to provide a platform that operates stably.
