Description

Blockchain-based authenticity check system and its driving method {System for Detecting Counterfeit product based on block chain and Driving Method thereof}

The present invention relates to a system for checking authenticity based on a block chain and a method of driving the same, and more particularly, to a system for checking authenticity based on a block chain using a QR code including genuine product data of a product, and a driving method thereof.

In general, producers attach specific trademarks to their products and sell them so that consumers can identify their own products and other people's products.

In addition, the consumer can purchase the product by recognizing that the product is a product produced by a specific producer through the trademark. In other words, consumers can trust the product according to their brand recognition and function as an identification mark.

However, due to the development of counterfeit technology, it is difficult for consumers to identify counterfeit products with the naked eye.In recent years, manufacturers have developed and provided anti-counterfeiting devices or genuine identification devices that can determine whether or not a product is genuine by incorporating various scientific technologies. have.

For example, the conventional alcohol anti-counterfeiting service system registered with the Korean Intellectual Property Office (Registration Patent No. 10-1441057, registration date: September 5, 2014) registered identification codes of alcoholic beverages corresponding to disposable products on the central server. When a user who purchases the alcoholic beverage in the state transmits a product identification code, the central server matches the transmitted product identification code with the registered identification codes to check whether they matched, and notifies the user of the confirmed result. , It guides users to check whether the container of the liquor product has been reused.

However, in the conventional mainstream anti-counterfeiting service system, in order to transmit the identification codes of products to the central server, the user obtains the identification codes of products from the mainstream products by wireless reception of the radio (Rfid) tag attached to the mainstream products. Therefore, by attaching wireless tags to all liquor products manufactured and produced, manufacturing costs are increased, and in the case of a central server that registers and manages identification codes of liquor products, the central server is managed by the company that manufactures or distributes the liquor. There is a problem in not recognizing this when forged by a managing company.

On the other hand, blockchain is currently famous as the underlying technology of digital currency such as Bitcoin and Ethereum, but its underlying technology has potential to be used in a wide range of industries such as logistics, asset management, health, voting, and public sectors, as well as finance and investment. Fortune-telling.

Blockchain provides confidence in the immutability of records and a consistent agreed state by allowing all participants on the network to transparently verify transaction records without an authorized intermediary. In addition, the smart contract function that guarantees automatic execution according to conditions allows the development of applications that provide new trust models in various fields.

Meanwhile, in the process of realizing this potential, issues such as how to secure the demand for personal information protection in the transparency provided by technology, and how to newly interpret legal requirements established according to the existing centralized environment It has emerged and is becoming the focus of discussion.

A number of consortiums have been organized around IT (information technology) companies, financial sectors, and governments to realize the possibility of such a blockchain, and various development efforts are being made at home and abroad. Meanwhile, in recent years, there is a growing demand for standardization to support the realization of these technologies and to provide appropriate guidelines for interoperability and safety. In order to meet these demands, ISO and ITU-T, representatives of public standardization organizations in 2017, started standardization activities related to blockchain in earnest.

It is an exemplary diagram for explanation.

In one embodiment, the blockchain-based authenticity check system 10 is operated in conjunction with a blockchain network that processes transactions related to the generation and use of genuine product data.

Blockchain network consists of a number of nodes connected by a network.

Each node is a computing terminal or server, and stores the transaction message ledger (hereinafter referred to as the blockchain ledger) in which transaction messages are recorded in a blockchain. Therefore, all nodes synchronize with each other and have the same blockchain ledger.

Specifically, a transaction message (or message) is a message representing one transaction, such as a message requesting personal information, an authentication result message, a message providing personal information, and the like. The hash value of each transaction message is calculated, and the hash values are formed in a blockchain.

At this time, the blockchain ledger includes both a block chain consisting of hash values of each message as a chain of blocks and a transaction message (or message). By viewing the message of the blockchain ledger, the contents of the message can be viewed, and the authenticity of the message can be verified by authenticating the hash value of the blockchain.

In particular, when a node performs a transaction, it adds a new transaction message to its blockchain ledger and transmits the added block information to other nodes. Additional information or blocks are added to the existing blockchain ledger as a blockchain.

In addition, other nodes receive block information added from the previously updated node and add block information to their own blockchain ledger. Preferably, the node transmits update information (additional information) about the blockchain to be added to nodes located around it.

Then, the neighboring nodes record the update information on the blockchain in their own blockchain ledger, and transmit it to their neighboring nodes again. Therefore, all nodes located in the blockchain network synchronize the blockchain ledger and all have the same blockchain ledger containing genuine product data.

The blockchain-based authenticity check system 10 is a method in which the producer terminal 12, the intermediate seller terminal 16, and the purchaser terminal 14 operate directly as a block chain node or access the block chain node. Is included in the blockchain ledger, added, or extracted so that it can be verified.

Blockchain-based authenticity check system 10 according to an embodiment is a user operating in conjunction with a camera so that a producer registers genuine product data for a product and a buyer can check whether the product to be purchased is a genuine product.
