In fact, luxury goods are difficult to access by the general public because of their high consumer prices, but low-priced counterfeit goods that are replicas of luxury goods form a relatively low price range, are almost identical to genuine goods, and are difficult to distinguish with the human eye, Since there is no proper way to clearly distinguish between genuine and counterfeit products in the process (especially online), consumers who want to purchase luxury goods at reasonable prices are deceived into purchasing counterfeit goods as genuine products. There are many consumers who buy counterfeit products even though they know they are not.

Conventionally, in order to determine the authenticity of products circulated or sold in the market, a method of enclosing a quality assurance certificate with a product or a method of attaching a barcode, a guarantee mark or a hologram sticker to the product is used.

However, most anti-counterfeiting/counterfeiting/forgery prevention technologies, including quality assurance cards, certification marks, hologram stickers, QR codes, as well as RFID, fluorescent inks, etc. Because it is possible, there is a problem that it is difficult to trust that it is genuine by itself.

3 is a flowchart of a block chain-based product quality assurance and transaction history management method according to another embodiment of the present invention.

Referring to FIG. 3 , in step S110 , the server 100 may obtain a token issuance request for one or more products from the manufacturer. For example, the server 100 may provide a user interface (UI) for providing a block chain-based product quality assurance and transaction history management method, and may receive a token issuance request from the manufacturer through the UI. and receive payment for the token to be issued through the payment process of the UI.

At this time, the server 100 may determine the amount of tokens to be issued according to the number of tokens to be issued and a token issuance method. It is not limited thereto, and various factors such as the manufacturer's grade according to a preset standard (e.g., a grade set differently according to the number of token issuance requests per unit period or the number of issued tokens per unit period) may be applied together and can be determined. .

Here, the token issuance request means a request to issue a blockchain-based token as a quality assurance certificate for a specific product, and attribute information about the product (eg, product type, etc.), the number of tokens to be issued, and tokens may include information on at least one of the issuance methods, but is not limited thereto.

In addition, here, the token may include a non-fungible token (NFT) of the Ethereum Request for Comment (ERC)-721 standard, but is not limited thereto.

In step S120, the server 100 may issue a token for the product in response to the token issuance request obtained from the manufacturer in step S110.

In various embodiments, the server 100 issues tokens for a plurality of products in response to obtaining a token issuance request for the plurality of products, and tokens corresponding to the plurality of products based on attributes for the plurality of products. You can decide how to issue

For example, when the server 100 obtains a token issuance request for a plurality of products from the manufacturer, the server 100 may determine the attributes of the plurality of products, and the attributes of the plurality of products are set as the first attribute (eg, limited edition). product), a plurality of tokens including a unique identifier code without mutual regularity may be independently issued corresponding to each of the plurality of products.

In addition, when the attribute for the plurality of products includes the second attribute (eg, mass-produced product), the server 100 may provide a plurality of tokens including a unique identifier code having mutual regularity to each of the plurality of products. can be issued at the same time.

In general, there is a need for manufacturers to have a higher value than other mass-produced products in the same or similar fields for products that produce and sell only a small number of predetermined products, such as limited edition products. According to these needs, the server 100 according to various embodiments of the present invention generates tokens that are independently distinguished by issuing tokens corresponding to each product individually for products that want to have a high value, such as a limited edition product, By recording this on the block chain network (step S130 to be described later), each token and the product corresponding to the token can be evaluated with a higher value compared to the mass-produced product.

On the other hand, in order to record and register token information on the blockchain network, a predetermined registration fee (gas, a fee when executing a smart contract according to a transaction for token movement or ownership change) is required. Since the proportion according to the number of times to register information about the token is greater than the proportion according to the number of information about the token to be registered at one time of registration, as described above, tokens for each product are individually issued, and the When recording and registering individually on the network, a large registration fee is incurred.

That is, if tokens are individually issued as above for mass-produced and sold products, such as mass-produced products, and they are individually registered on the blockchain network, excessive costs are reduced in the process of issuing and registering tokens for product assurance. There is a problem that it has to spend, and thus the profit of the manufacturer may be reduced. In addition, if the price of a product is raised in order to solve the problem of decreasing profits, there is a problem that the sales volume of the product may be adversely affected.

Accordingly, the server 100 simultaneously issues a plurality of tokens including a unique identifier code with mutual regularity (eg, consecutive numbers) for a plurality of products mass-produced and sold, such as a mass-produced product, and At the same time, by recording on the blockchain network, it has the advantage of saving the registration fee compared to the method of issuing tokens individually for each product and recording on the blockchain network.

In various embodiments, when the plurality of products are mass-production products of the same type, the server 100 may issue one token corresponding to the plurality of products, and divide the issued token according to the number of the plurality of products. Thus, a plurality of unit tokens may be generated, and each of the plurality of generated unit tokens may be allocated to each of a plurality of products. For example, when the server 100 receives a token issuance request for 1000 products of the same type, it issues one token for 1000 products, divides it into 1000 unit tokens, and provides each of the 1000 products. Unit tokens can be allocated.

In various embodiments, the server 100 determines the attribute for a specific product based on the token issuance request for the specific product, but if the specific product is a product that can be held by dividing ownership by a certain ratio, Multiple tokens can be issued for Through this, the server 100 may set the ownership stake for the corresponding product according to how many tokens the user has corresponding to the corresponding product.

In various embodiments, the server 100 may recycle tokens previously issued to each of a plurality of products without issuing a new token for a specific product in some cases.

For example, in the case of a product having a lifespan of a certain period, when the lifespan expires, the product can no longer be used or resold and is discarded. recorded on the table.

In consideration of this point, the server 100 provides a token corresponding to a product for which a preset period (eg, a period longer than the product lifespan) has elapsed based on the token issuance time among a plurality of products having a lifespan of a predetermined period. You can classify and store and manage (recycled tokens) according to By allocating to , it is possible to prevent wasted tokens from being generated.

Thereafter, the server 100 may record on the block chain network that the recycling token corresponds to the newly allocated product, and that the owner of the product corresponding to the recycling token is the manufacturer.

Here, the token recycling method performed by the server 100 is described as recycling a token corresponding to the product when a product having a lifespan of a predetermined cycle expires, but is not limited thereto, and has no lifespan. Tokens for products can also be recycled. For example, the server 100 may receive a return request for a token corresponding to the product from the owner set in advance for a specific product, and in response to the return request, set the token corresponding to the product as a recycling token and classify it separately can be stored and managed. In this case, the server 100 may provide a predetermined reward to the user who has returned a specific token.

Here, in the block chain-based product quality assurance and transaction history management method according to various embodiments of the present invention, it is explained that the token issuance method is automatically determined by analyzing the properties of the product, and the token is issued accordingly. , but not limited thereto, by providing the manufacturer with information on the token issuance method that is implemented in the form of directly inputting the token issuance method from the manufacturer, or determined by analyzing the properties of the product, so that the manufacturer can determine the appropriate issuance method for the product It may be implemented in a form that assists in making a decision.

In step S130, the server 100 may record information about the token issued in step S120 on the blockchain network. For example, the server 100 provides information about the token (eg, information about a product corresponding to the token, a unique identifier code of the token, and information about the owner (eg, the wallet of the user who owns the product corresponding to the token) address, and the first owner is the manufacturer), etc.), and by transmitting the created block on the blockchain network, information about the token can be distributed and stored on the distributed database of the blockchain network. have.

Here, the token issued by the server 100 is a non-fungible token (NFT) of the ERC-721 standard based on Ethereum, and the blockchain network may be an Ethereum network, but is not limited thereto.

In various embodiments, when the server 100 obtains an activation request for the first product from the user, based on whether information about the first token corresponding to the first product is recorded on the blockchain network It may be determined whether the first product is genuine. Hereinafter, it will be described with reference to FIGS. 4 to 6 .

4 is a flowchart for explaining a genuine product authentication method and an owner registration method for a product in various embodiments, and FIG. 5 is a flowchart illustrating a genuine product authentication process and an owner registration process for a primary purchaser of a product in various embodiments. 6 is a diagram illustrating a genuine product authentication process for a secondary purchaser of a product and a change owner registration process according to various embodiments of the present disclosure.

4 to 6 , in step S210 , the server 100 may obtain a genuine product authentication request for the first product from the user who purchased the first product. For example, the server 100 may provide a UI for providing a product activation service to the user terminal 200, and information about the first token issued in response to the first product through the UI (eg, : A request for activation of the first product including a unique identification code) may be input.

Here, the first token is implemented in a form in which at least a portion can be attached (eg, an adhesive material (eg, an adhesive) is applied to at least a portion of a printed matter on which the first token (or a unique identification number of the first token) is printed. ), attached to at least a part of the first product, or implemented in an independent form (eg, a chip, USB, etc.) and enclosed with the first product, and the user Information on the token or information on the first token implemented in the form of a chip or USB may be input through the UI, but is not limited thereto.

In step S220, the server 100 determines whether or not information on the first token is recorded on the block chain network based on the information about the first token input from the user, thereby determining whether the first product is genuine. can judge

In step S230, when it is determined that the information on the first token is not recorded on the block chain network through step S220, the server 100 may determine that the first product corresponding to the first token is a counterfeit product, , a genuine product authentication result including information on the determination result (eg, information guiding that the first product is a counterfeit product) may be provided to the user.

In step S240, when it is determined that information on the first token is recorded on the block chain network through step S220, the server 100 may determine that the first product corresponding to the first token is genuine, , an activation result including information on the determination result (eg, information guiding that the first product is genuine) may be provided to the user.

As described with reference to FIG. 3 , the server 100 issues a token corresponding to the genuine product and records it on the blockchain network as the manufacturer requests token issuance to produce a genuine product and sell it. That is, the fact that the token information is recorded on the blockchain network means that the manufacturer has formally requested the issuance of the token, which means that the product corresponding to the token is a genuine product. , it is possible to accurately determine whether the product corresponding to the token is genuine or not even by checking whether information about the token is recorded on the blockchain network.

In addition, since the server 100 distributes and stores information about the token on the block chain network, information about the token recorded on the block chain network cannot be forged or falsified, so check whether the information about the token is recorded The reliability of the judgment result (whether the first product is genuine or not) derived according to whether the product is genuine or not can be secured.

Thereafter, the server 100 may perform a procedure of registering the user as the owner of the first product in response to determining that the first product is genuine through the above process.

In step S250 , the server 100 may determine whether there is a preset owner of the first product before performing the procedure of registering the user as the owner of the first product. For example, the server 100 may determine the presence or absence of a preset owner according to whether the current owner of the first product is a manufacturer based on information about the first token recorded on the block chain network.

As an example, when the preset owner of the first product is the manufacturer, the server 100 provides information on the owner of the token corresponding to the first product on the block chain network of the manufacturer that produces and sells the first product. If it is set as a wallet address, it can be determined that there is no preset owner for the first product, and when the preset owner is not a manufacturer, that is, information about the owner of the token corresponding to the first product is If it is not the wallet address of the manufacturer, it may be determined that there is a preset owner for the first product. However, the present invention is not limited thereto.

In step S260 , when it is determined that there is no preset owner of the first product, the server 100 may generate a first transaction for registering the user as the owner of the first product. For example, when there is no preset owner for the first product, the server 100 may generate a transaction for moving the first token from the manufacturer's wallet to the user's wallet, but is not limited thereto.

In step S270 , when it is determined that there is a preset owner of the first product, the server 100 may generate a second transaction for changing the owner of the first product from the preset owner to the user.

For example, if there is a preset owner for the first product, the server 100 may identify the preset owner and user based on the wallet address by calling the preset owner and user's wallet, and the preset owner and a second transaction for moving the first token from the preset owner's wallet to the user's wallet in response to the user being identified may be generated.

In this case, in some cases, the seller who wants to sell counterfeit products purchases only tokens from the user who purchased the genuine product in order to sell the counterfeit product produced by them as genuine products, or purchase tokens (or information about tokens) from the user who purchased the genuine product. There may be cases where it is stolen and sold with or attached to a counterfeit product.

For the purpose of preventing this, when it is determined that there is a preset owner for the first product, the server 100 proves that the user actually purchased the product from the preset owner, that is, that a real transaction was performed. Proving evidence may be requested, and accordingly, the second transaction may be generated only when the user is authenticated as having actually purchased the product based on the evidence uploaded from the user.

In addition, as the pre-set owner of the genuine product loses or steals the product to which the token is attached (or the token itself implemented in an independent form), a third party who is not the pre-set owner of the product sells or sells the product For the purpose of preventing the sale of tokens corresponding to the product, the server 100 not only authenticates that the user actually purchased the product based on the evidence uploaded from the user as described above, but also allows the user to make a transaction. By verifying whether a target is a preset owner (eg, based on a wallet address between transaction targets), the second transaction can be generated only when the target who sold the product to the user is the preset owner.

In addition, for the purpose of preventing a seller who produces and sells counterfeit products by chance, acquires one token or a small amount of tokens corresponding to genuine products, copies them and applies them to a large number of products and sells them, ) is to move the corresponding token from the preset owner's wallet to the user's wallet even if the information about the corresponding token is recorded on the blockchain network when a large number of activation requests based on the same token are input within a preset period. The second transaction may not be generated.

In step S280, the server 100 records the first transaction generated in step S260 on the block chain network, so that the owner of the first product can be set as the user who purchased the product.

In addition, the server 100 may change the owner of the first product from a preset owner to a user by recording the second transaction generated in step S270 on the block chain network.

That is, the server 100 may provide information so that the authentication procedure for the genuine product and the current owner of the genuine product can be known through the above process.

In addition, the server 100 continuously records the transaction for the change of owner on the blockchain network as the owner of the product changes, so that not only information on who the current owner is, but also how much the owner has changed That is, it is possible to provide information on how many used transactions for the corresponding product have been made.

Referring to FIG. 7 , a block chain-based product quality assurance and transaction history management method according to various embodiments of the present invention aims to issue tokens serving as a guarantee at low cost in large quantities.
