[0080] Hereinafter, preferred embodiments of the present disclosure will be described in detail with reference to the attached drawings. The advantages and features of the present invention, and methods for achieving them, will become clearer with reference to the embodiments described in detail below together with the attached drawings. However, the technical spirit of the present invention is not limited to the following embodiments but may be implemented in various different forms. The following embodiments are provided only to complete the technical spirit of the present invention and to fully inform those skilled in the art of the present invention of the scope of the present invention, and the technical spirit of the present invention is defined only by the scope of the claims.

[0081] In describing the present disclosure, if it is determined that a detailed description of a related known configuration or function may obscure the gist of the present invention, the detailed description will be omitted.

[0082] Unless otherwise defined, the terms (including technical and scientific terms) used in the following examples may be used with meanings commonly understood by those of ordinary skill in the art to which this disclosure pertains; however, this may vary depending on the intentions of engineers working in the relevant field, precedents, the emergence of new technologies, etc. The terminology used in this disclosure is for the purpose of describing the embodiments and is not intended to limit the scope of this disclosure.

[0083] In the following examples, singular expressions include plural concepts unless the context clearly specifies that they are singular. Furthermore, plural expressions include singular concepts unless the context clearly specifies that they are plural.

[0084] In addition, terms such as first, second, A, B, (a), (b), etc. used in the following embodiments are only used to distinguish certain components from other components, and the nature, order, or sequence of the components are not limited by the terms.

[0085] Various embodiments of the present disclosure will be described below with reference to the attached drawings.

[0086] Hereinafter, with reference to FIG. 1, an environment in which a celebrity-related item authentication system is implemented will be described. FIG. 1 is a diagram illustrating an environment in which a celebrity-related item authentication system according to some embodiments of the present disclosure is implemented.

[0087] Referring to FIG. 1, a celebrity-related item authentication system may be configured to include a service server (10), a seller terminal (11), a celebrity terminal (12), an appraiser terminal (13), a buyer terminal (14), and a blockchain network (15). However, the scope of the present disclosure is not limited thereto. In some cases, the celebrity-related item authentication system may be configured to further include modules / devices / systems not illustrated in FIG. 1. Alternatively, the celebrity-related item authentication system may be configured to exclude at least some of the components (10 to 14) illustrated in FIG. 1.

[0088] A seller terminal (11) can transmit a request for authenticity verification for an item to be sold to the service server (10). A request for authenticity verification for an item means a request for verification regarding whether the item has been used by a specific celebrity.

[0089] When the service server (10) receives a request for authenticity verification for an item from a seller terminal (10), it can generate a seller authentication result and an item identity verification result, and generate appraisal information based on the generated seller authentication result and item identity verification result. The seller authentication result may include information regarding whether another buyer and seller match the last transaction record recorded on the blockchain. Specifically, the service server (10) can record the data included in the registration transaction for the item and the transaction transaction for the item on a blockchain shared within the blockchain network (15). The data included in the registration transaction for the item and the transaction transaction for the item will be described in detail with reference to FIGS. 6 and 7.

[0090] The product identity certification results may include information on whether the two products are identical by comparing the product characteristic data of the product actually used by the celebrity with the product the seller intends to sell.

[0091] When generating a product identity authentication result, the service server (10) can transmit a photograph taken when registering an item that the seller wishes to sell to the appraiser terminal (13) and receive actual measurement values ​​of the item from the appraiser terminal (13). The service server (10) can use the received actual measurement values ​​to construct actual measurement data and use the actual measurement data to generate a product identity authentication result.

[0092] The service server (10) may transmit a request for authenticity verification, including emotional information generated for an item the seller wishes to sell, to the celebrity terminal (12). The celebrity terminal (12) may transmit authentication information to the service server (10) regarding the authenticity of the item the seller wishes to sell. The authentication information may include information regarding whether the celebrity has actually used the item.

[0093] The service server (10) can transmit the above-mentioned emotional information and the above-mentioned authentication information to the purchaser terminal (14). The purchaser terminal (14) can display the above-mentioned emotional information and the above-mentioned authentication information on a display screen, thereby allowing the purchaser to confirm whether or not to purchase the item to be sold.

[0094] Next, the blockchain network (15) may refer to a network formed by multiple blockchain nodes. Multiple blockchain nodes may share the same blockchain, and sharing the same blockchain here may mean that each blockchain node maintains a blockchain in which the same data is recorded through a consensus algorithm. The blockchain network (15) may record various data received from the service server (10) on the blockchain, and may guarantee the integrity of the data recorded through the blockchain. Those skilled in the art are likely already familiar with the operation of blockchain nodes, the principles of blockchain, etc., and therefore, a detailed description thereof will be omitted.

[0095] In some embodiments, the blockchain network (15) may be implemented as multiple sub-blockchain networks that share different blockchains. As illustrated in FIG. 3, if the blockchain network (15) supports a multi-channel function (e.g., Hyperledger Fabric), each of the sub-blockchain networks (31, 33, 35) may refer to a blockchain network that forms a different channel. Here, a channel may refer to a small-scale (or virtual) network formed on the blockchain network (15) or a communication path between blockchain nodes belonging to the networks. When a multi-channel is formed on the blockchain network (15), only blockchain nodes belonging to the same channel share the same blockchain (see 32, 34, 36). Those skilled in the art are likely already familiar with the operating principles of a multi-channel-based blockchain network, and therefore, a detailed description thereof will be omitted. In this embodiment, each of the sub-blockchain networks (e.g., 31, 33, 35) may operate in a different manner (e.g., have different access control settings) or may assume different roles (e.g., a specific blockchain network may assume an anchoring role), which will be described later.

[0096] Meanwhile, in some embodiments, components (10 to 15) of the celebrity-related item authentication system may communicate via a network. Here, the network may be implemented as any type of wired / wireless network, such as a Local Area Network (LAN), a Wide Area Network (WAN), a mobile radio communication network, or Wibro (Wireless Broadband Internet).

[0097] For ease of understanding, the following description assumes that all steps / operations of the methods described below are performed on the aforementioned service server (10). Therefore, if the subject of a specific step / operation is omitted, it can be understood that it is performed on the service server (10). However, in an actual environment, some steps / operations of the methods described below may be performed on other computing devices.

[0098] Hereinafter, the inter-component operations of the celebrity-related item authentication system will be described with reference to FIG. 2. FIG. 2 is a signal flow diagram illustrating the sequence in which celebrity-related item authentication and transaction methods according to some embodiments of the present disclosure are performed.

[0099] Referring to FIG. 2, the seller terminal (11) is a terminal of a seller who wishes to sell the first product, and can transmit a request for authenticity authentication for the first product to the service server (10) (S20).

[0100] When a seller terminal (11) transmits a request for authenticity verification for the first product to the service server (10), the service server (10) can generate a seller authentication result (S21). The seller authentication result may include information regarding whether the seller matches the last transaction record recorded on the blockchain within the blockchain network (15).

[0101] Thereafter, the service server (10) must configure actual measurement data for the first product to generate an item identity authentication result. To configure actual measurement data for the first product, the service server (10) can transmit data in which a photograph taken at the time of sale of the first product and actual measurement points in the photograph taken at the time of sale are overlaid to the appraiser terminal (13) (S22).

[0102] The emotional terminal (13) can measure actual values ​​for each of the actual measurement points of the first product based on a photograph taken at the time of sale of the first product, and transmit the measured actual values ​​to the service server (10) (S23).

[0103] Thereafter, the service server (10) can configure actual measurement data based on the received actual measurement values ​​and generate an article identity authentication result by comparing whether the actual measurement data and article characteristic data related to the first article are identical (S24).

[0104] Thereafter, the service server (10) can generate appraisal information for the first item based on the seller authentication results and the item identity authentication results (S25). The service server (10) can then send a request for authenticity verification for the first item, including the appraisal information, to the celebrity terminal (12) (S26). The request for authenticity verification may be a request to confirm whether the celebrity actually used the first item.

[0105] The celebrity terminal (12) can transmit authentication information regarding the authenticity of the first product to the service server (10) (S27). The authentication information may include information regarding whether the celebrity actually used the product.

[0106] Thereafter, the service server (10) can transmit emotional information and authentication information to the buyer terminal (14) (S28). The buyer terminal (14) can display the emotional information and authentication information on a display screen, thereby allowing the buyer to confirm whether or not to purchase the item to be sold.

[0107] According to embodiments of the present disclosure, there is an advantage in that the seller can perform an objective appraisal of an item to be sold and at the same time, perform a celebrity-specific authentication process for the item, thereby closely verifying whether the item is an item actually used by the celebrity.

[0108] Hereinafter, with reference to FIG. 4, a method for authenticating and trading celebrity-related items according to one embodiment of the present disclosure will be described. FIG. 3 is a flowchart illustrating the operation of a method for authenticating and trading celebrity-related items according to one embodiment of the present disclosure.

[0109] Referring to FIG. 4, the service server (10) may receive a request for authenticity verification for a first product the seller wishes to sell from the seller terminal (11) (S100). The request for authenticity verification refers to a request for verification regarding whether the first product has been used by a specific celebrity.

[0110] Thereafter, the service server (10) can generate appraisal information for the first item (S200). The appraisal information may be generated by querying and comparing transaction records and item characteristic data based on the first item's unique ID stored in the item identification chip embedded in the first item. The first item's unique ID and item characteristic data may be data recorded on a blockchain within the blockchain network (15). The method for generating appraisal information will be described in detail later.

[0111] Thereafter, the service server (10) may transmit an authenticity verification request, including emotional information, to the celebrity terminal (12), which is the terminal of the original owner of the first item (S300). The authenticity verification request may be a request to confirm whether the celebrity actually used the first item.

[0112] Thereafter, the service server (10) may receive authentication information regarding the authenticity of the first product from the celebrity terminal (12) in response to the authenticity verification request (S400). The authentication information may include information regarding whether the celebrity actually used the product.

[0113] Upon receiving the authentication information from the celebrity terminal (12), the service server (10) may credit a portion of the sales proceeds of the first item to the account of the celebrity, the original owner (S500). By providing a reward for the celebrity authenticating the authenticity of the first item through the celebrity terminal (12), the service server can encourage the celebrity to be more meticulous in authenticating the authenticity of the item the seller wishes to sell.

[0114] If the service server (10) receives authentication information from the celebrity terminal (12) confirming that the first item is genuine, a portion of the sales proceeds from the first item can be credited to the seller's account (S600). By offering a reward for providing items actually used by celebrities to a platform that provides celebrity-related item authentication and transaction methods according to the present disclosure, sellers can encourage the use of the platform to trade celebrity-related items.

[0115] According to embodiments of the present disclosure, there is an advantage in that the seller can perform an objective appraisal of an item to be sold and at the same time, perform a celebrity-specific authentication process for the item, thereby closely verifying whether the item is an item actually used by the celebrity.

[0116] Hereinafter, with reference to the drawings below in FIG. 5, a method for a service server (10) to generate emotional information will be described.

[0117] FIG. 5 is an exemplary diagram illustrating an article to be authenticated according to another embodiment of the present disclosure.

[0118] Referring to FIG. 5, a first article (40) that a seller wants to sell is illustrated. The first article (40) has a built-in article identification chip (41) that can prove that the article was used by the celebrity when the celebrity sells the article through a service provider via a service server (10). A service provider using the celebrity-related article authentication and transaction method according to the present disclosure may insert the article identification chip (41) into a specific location of the first article (40) in advance. The article identification chip (41) may be a chip with a unique ID assigned to each chip, such as an NFC chip, but the present disclosure is not limited thereto. The service server (10) may scan the article identification chip (41) and generate a seller authentication result and an article identity authentication result using the first article unique ID stored in the article identification chip (41).

[0119] Hereinafter, with reference to FIGS. 6 and 7, a description will be given of the transactions performed by the service server (10) in the process of generating emotional information using blockchain technology.

[0120] FIG. 6 is a diagram illustrating a registration transaction of an item recorded in a blockchain within a blockchain network (15) according to another embodiment of the present disclosure.

[0121] Referring to FIG. 6, a registration transaction (20) for an item recorded on a blockchain is illustrated. The registration transaction (20) may include the item's unique ID (21), item characteristic data (52), celebrity information (23), and transaction records (24). However, the scope of the present disclosure is not limited thereto, and in some cases, it may be configured to include additional information not shown in FIG. 6.

[0122] A registration transaction (20) may be a transaction initially performed by a service provider through the service server (10) when a celebrity sells an item he or she used through the service provider through the service server (10). Items registered according to the registration transaction (20) may be maintained and managed by the service server (10).

[0123] The unique ID (21) may be an ID identified through an item identification chip embedded in the product by a service provider that provides services through a service server (10) when the celebrity sells the product they used, to distinguish that the product was used by the celebrity. The service server (10) may search for information related to the unique ID (21) on the blockchain within the blockchain network (15) to generate a seller authentication result or an item identity authentication result.

[0124] The product characteristic data (52) may be data including information about the characteristics of an item used by a celebrity. The product characteristic data (52) may include multiple (characteristic, value) data. For example, assume that the item used by the celebrity is a luxury bag, the first characteristic is a logo type, and the logo types range from the first to the tenth logo types, each of which has a distinct shape. The logo type of the first item may be the fourth logo type. In this case, the product characteristic data for the first characteristic may include (logo type, fourth type) data.

[0125] Celebrity information (23) may be information containing personal information such as the name of a celebrity who used the product.

[0126] A transaction record (24) may be a record of a transaction of an item. Transaction records (24) may be continuously generated through the resale of an item. Therefore, a transaction record (24) may include multiple transaction records. A transaction record (24) may be generated by a transaction transaction of an item recorded on a blockchain. The transaction transaction of an item may be recorded on a blockchain within a blockchain network (15). The following describes the transaction record (24) with reference to FIG. 7. FIG. 7 is a diagram illustrating a transaction transaction of an item recorded on a blockchain within a blockchain network (15) according to another embodiment of the present disclosure.

[0127] Referring to Figure 7, a transaction (24) of goods recorded in a blockchain is illustrated.

[0128] Each transaction record or transaction transaction (24) may include information about the transaction hash value, TxnHash, status information regarding whether the transaction was successfully concluded, timestamp information regarding the time the transaction was concluded, From information recording the seller's wallet ID, To information recording the buyer's wallet ID, Value information recording the price of the item that is the subject of the transaction, Transaction Fee information recording the transaction fee, and a unique ID information that can identify the traded item. However, the present disclosure is not limited thereto, and in some cases, the transaction transaction (24) may include other information. For example, when trading an item, authentication information may also be included where the celebrity, who is the original owner of the item, certifies that the item was used by him / her.

[0129] Hereinafter, a method for generating emotional information according to one embodiment of the present disclosure will be described with reference to FIG. 8. FIG. 8 is a detailed flowchart illustrating some operations of the celebrity-related item authentication and transaction method described with reference to FIG. 4.

[0130] Referring to FIG. 8, the service server (10) can scan the product identification chip embedded in the first product delivered from the seller to obtain the first product unique ID stored in the product identification chip (S210). The first product and the product identification chip embedded in the first product are as described in FIG. 5. As described with reference to FIG. 6, the first product unique ID may be an ID identified through the product identification chip embedded in the first product that a celebrity used, when the celebrity sold the first product that he or she used through a company that provides services through the service server (10), to distinguish that the product is the first product that the celebrity used.

[0131] The service server (10) can retrieve the last transaction record related to the unique ID of the first item from the first blockchain (S211). The first blockchain refers to a blockchain within the blockchain network (15). Since all registration transactions and transaction transactions for the first item are recorded on the first blockchain, the service server (10) can always retrieve transaction records and item characteristic data for the first item. The last transaction record may be configured as described with reference to FIG. 7.

[0132] Thereafter, the service server (10) can generate a seller authentication result by checking whether the buyer (information on To in FIG. 7) according to the last transaction record matches the seller selling the first product (S212). The service server (10) can obtain the seller's wallet ID by looking up the ID of the seller terminal (11). The service server (10) can generate a seller authentication result by checking whether the obtained seller's wallet ID matches the buyer's wallet ID according to the last transaction record.

[0133] Thereafter, the service server (10) can generate emotional information including the seller authentication result (S213). If the buyer according to the last transaction record matches the seller of the first item, the service server (10) can generate a seller authentication result indicating that the buyer according to the last transaction record matches the seller of the first item. If the buyer according to the last transaction record does not match the seller of the first item, the service server (10) can generate a seller authentication result indicating that the buyer according to the last transaction record does not match the seller of the first item.

[0134] According to this embodiment, the emotional information provided to the celebrity can include information about whether the seller is the owner of the item as recorded in the blockchain transaction records, based on blockchain-based transaction records. Therefore, this embodiment offers the advantage of allowing the celebrity to more closely verify the authenticity of an item by referencing the seller's authentication results when verifying its authenticity.

[0135] Hereinafter, with reference to FIG. 9, a method for generating emotional information according to one embodiment of the present disclosure will be described. FIG. 8 is a detailed flowchart illustrating some operations of the celebrity-related item authentication and transaction method described with reference to FIG. 4.

[0136] Referring to FIG. 9, the service server (10) can scan the product identification chip embedded in the first product delivered from the seller and obtain the first product unique ID stored in the product identification chip (S220).

[0137] Thereafter, the service server (10) can retrieve product characteristic data related to the first product's unique ID from the first blockchain (S221). The first blockchain may be a blockchain within a blockchain network (15). Since all registration transactions and transaction transactions for the first product are recorded on the first blockchain, the service server (10) can always retrieve transaction records and product characteristic data for the first product.

[0138] Thereafter, the service server (10) can generate a product identity authentication result by comparing the product characteristic data with the actual measurement data for the first product (S222).

[0139] Hereinafter, product characteristic data will be described with reference to FIG. 10. FIG. 9 is a diagram illustrating product characteristic data according to another embodiment of the present disclosure.

[0140] The product characteristic data may be data included in the registration transaction of the first product recorded on the first blockchain. As previously described with reference to FIG. 6, the product characteristic data (52) may be data including information on the characteristics of an item used by a celebrity. The product characteristic data (52) may include multiple (characteristic, value) data. For example, referring to FIG. 9, it is assumed that the first item used by the celebrity is a luxury bag (90), the first characteristic is a logo type, and the logo types range from the first logo type to the tenth logo type, and each logo type has a distinct shape. The logo type (91) of the first item may be the fourth logo type. In this case, the product characteristic data for the first characteristic may include (logo type, fourth type) data.

[0141] In one embodiment, each of the plurality of (characteristic, value) data included in the product characteristic data may be composed of (encrypted characteristic, encrypted value). At this time, the encrypted characteristic may be a characteristic identifier encrypted by the public key of the service server (10), and the encrypted value may be a value encrypted by the public key of the service server (10), and the public key of the service server (10) may be a public key according to a PKI (Public Key Infrastructure) structure. That is, the plurality of (characteristic, value) data included in the product characteristic data may be encrypted by the public key of the service server (10) and then stored in the blockchain.

[0142] When implementing PKI, asymmetric encryption is performed using a public key and a private key pair. While the public key of the service server (10) can be freely shared and accessed by all entities, the private key is always kept private and secure, and can only be accessed by the administrator on the service server (10) side who has been issued the private key. Therefore, in the above embodiment, since the encrypted characteristics and encrypted values ​​can only be decrypted using the private key of the service server (10), it is possible to prevent entities other than the administrator on the service server (10) from acquiring multiple (characteristic, value) data included in the product characteristic data.

[0143] Therefore, according to the above embodiment, there is an advantage in that attempts to counterfeit the first article can be blocked at the source by preventing the (characteristic, value) data included in the article characteristic data of the first article from being leaked to the outside.

[0144] Hereinafter, a method for generating an item identity authentication result will be described with reference to FIGS. 11 and 12. FIGS. 11 and 12 are diagrams illustrating UI screens displayed on an emotional terminal according to another embodiment of the present disclosure.

[0145] In one embodiment, the service server (10) may retrieve a photo taken during registration of the first item corresponding to the unique ID of the first item. The photo taken during registration of the first item may be information included in the registration transaction of the item recorded on the blockchain within the blockchain network (15). The photo taken during registration of the first item may be overlaid with item characteristic data unique to the first item. For example, referring to FIG. 11, a photo (100) taken during registration of the first item is illustrated. The first item may be a luxury bag, the first characteristic (100a) may be a logo type (100b), and the logo type (100c) of the first item may be Type 1.

[0146] Thereafter, the service server (10) can display actual measurement points corresponding to each of the plurality of (characteristic, value) data included in the product characteristic data by overlaying them on the photograph taken when registering the first product. For example, referring to FIG. 11, the service server (10) can display actual measurement points by overlaying them on the photograph taken when registering the first product (100) by indicating that the logo type (100b) (=product characteristic data) of the first product is type 1 (100c).

[0147] In one embodiment, the service server (10) may not display values ​​corresponding to actual measurement points on the photograph taken when registering the first item. For example, referring to FIG. 12, the service server (10) may display on the photograph (100) taken when registering the first item that the first item is a luxury bag and that the first characteristic (110a) is a logo type (110b), but may not display that the logo type (110b) requiring actual measurement is Type 1. This has the advantage of allowing the appraiser to conduct an objective appraisal without having to know in advance the values ​​corresponding to specific characteristics when measuring the first item.

[0148] Meanwhile, the service server (10) can transmit a photo taken when selling the first item to the appraiser terminal (13). The appraiser terminal (13) can display the received photo taken when selling the first item and the photo taken when registering the first item side by side on the display unit of the appraiser terminal (13). For example, referring to FIG. 10, the appraiser terminal (13) can display a photo taken when selling the first item (100) and a photo taken when selling the first item (101) side by side on the display unit of the appraiser terminal (13).

[0149] Thereafter, the appraiser can compare the photos taken when registering the first item with the photos taken when selling the first item, and input the actual measurement values ​​for the actual measurement points in the photos taken when selling the first item into the appraiser terminal (13). The appraiser terminal (13) can transmit the actual measurement values ​​for the actual measurement points in the photos taken when selling the first item to the service server (10). The service server (10) can receive the actual measurement values ​​for each actual measurement point from the appraiser terminal (13).

[0150] For example, referring to FIG. 11, the appraiser can compare a photo (100) taken when registering the first item and a photo (101) taken when selling the first item, and input the actual measurement value for the type (101a) of the logo, which is the actual measurement point of the photo taken when selling the first item, into the input unit (102) of the appraiser terminal. The appraiser terminal (13) can transmit the actual measurement value (e.g., Type 1) for the type (101a) of the logo, which is the actual measurement point of the photo (101) taken when selling the first item, to the service server (10). Thereafter, the service server (10) can configure actual measurement data using the actual measurement value received from the appraiser terminal (13). For example, referring to FIG. 11, if the appraiser appraises the logo type, which is the first characteristic of the luxury bag, as type 1 in the photo (101) taken when the first item was sold, the actual data regarding the logo type may be composed of (logo type, type 1). On the other hand, if the appraiser appraises the logo type, which is the first characteristic of the luxury bag, as type 2 in the photo (101) taken when the first item was sold, the actual data regarding the logo type may be composed of (logo type, type 2).

[0151] Meanwhile, in one embodiment, instead of the appraiser directly comparing the photo taken when registering the first item with the photo taken when selling the first item, the appraiser uses an artificial intelligence-based image recognition deep learning model distributed to the appraiser terminal (13) to compare the photo taken when registering the first item with the photo taken when selling the first item, thereby determining whether the item according to the photo taken when registering the first item and the item according to the photo taken when selling the first item are the same item. At this time, the artificial intelligence-based image recognition deep learning model can determine whether the item characteristic data related to the first item in the photo taken when registering the first item and the item characteristic data related to the first item in the photo taken when selling the first item match using deep learning technology.

[0152] Thereafter, the emotional terminal (13) can transmit to the service server (10) the determination result as to whether the product according to the photograph taken when registering the first product and the product according to the photograph taken when selling the first product are the same product. The service server (10) can use the determination result to generate a product identity authentication result.

[0153] According to this embodiment, instead of employing an appraiser in the appraisal process to generate product identity authentication results, there is an advantage in that more accurate appraisal results can be provided by using an artificial intelligence-based image deep learning model.

[0154] This is explained again with reference to Figure 9.

[0155] The service server (10) can generate a product identity authentication result by comparing the product characteristic data with the actual measurement data for the first product (S222).

[0156] Let me explain using the previous example.

[0157] As shown in FIG. 11, the first product is a luxury bag (100), the first characteristic (100a) is a logo type (100b), and the logo type (100c) of the first product may be Type 1. In other words, the product characteristic data for the first characteristic of the first product may be data including (logo type, Type 1).

[0158] At this time, if the appraiser appraises the logo type (100b), which is the first characteristic (100a) of the luxury bag (100), as type 1, and the actual measurement data regarding the logo type (= first characteristic) is composed of (logo type, type 1), the product characteristic data regarding the first characteristic of the first product and the actual measurement data regarding the first characteristic match. Accordingly, the service server (10) can generate a product identity authentication result indicating that the product characteristic data regarding the first characteristic of the first product and the actual measurement data regarding the first characteristic match.

[0159] On the other hand, if the appraiser appraises the logo type (100b), which is the first characteristic (100a) of the luxury bag (100), as type 2, and the actual measurement data for the logo type (= first characteristic) is composed of (logo type, type 2), the product characteristic data for the first characteristic of the first product and the actual measurement data for the first characteristic do not match. Accordingly, the service server (10) can generate a product identity authentication result indicating that the product characteristic data for the first characteristic of the first product and the actual measurement data for the first characteristic do not match.

[0160] Thereafter, the service server (10) can generate emotional information including the product identity authentication result (S223).

[0161] According to this embodiment, the emotional information provided to the celebrity can include information about whether the actual measurement results of the item match the characteristics recorded on the blockchain, based on blockchain-based product transaction records. Therefore, this embodiment has the advantage of allowing the celebrity to more closely verify the authenticity of an item by referencing the product identity verification results when verifying its authenticity.

[0162] Meanwhile, in one embodiment, the service server (10) may transmit celebrity characteristic data that is distinct from the characteristic data included in the emotional information generated regarding the first item to the celebrity terminal (12) and that can only be identified by the celebrity who actually used the first item. The celebrity characteristic data may be data regarding characteristics that are displayed on the first item and that can only be identified by the celebrity. For example, referring to FIG. 13, let's say the first item is a luxury bag (130) used by a celebrity. If the celebrity sells the luxury bag (130) through a company that provides services via the service server (10), the celebrity may sign the name "Kim Bae-woo" (132), which cannot be identified with the naked eye, at the bottom of the luxury bag (130) so that only the celebrity can identify it. The signature may be celebrity characteristic data that only the celebrity can identify.

[0163] The above celebrity characteristic data may be data stored only in the service server (10). By preventing the service server (10) and third parties other than the celebrity from identifying the celebrity characteristic data, there is an advantage in that the celebrity can more closely authenticate the authenticity of the first product.

[0164] Thereafter, the celebrity may authenticate the authenticity of the first item only when the service server (10) receives a response that matches the celebrity characteristic data. By authenticating the authenticity of the first item only when the celebrity specifies the celebrity characteristic data, the reliability of the authentication information regarding the authenticity of the celebrity's first item can be enhanced.

[0165] Meanwhile, in one embodiment, the service server (10) may transmit authentication information and emotional information received from the celebrity terminal (12) to the purchaser terminal (14) of the first product. The emotional information may include the seller authentication result described with reference to FIG. 8 and / or the product identity authentication result described with reference to FIG. 9.

[0166] According to this embodiment, by transparently providing the appraisal information generated in the process of a celebrity authenticating the authenticity of the first product to the purchaser terminal (14) and the authentication information directly provided by the celebrity regarding the authenticity of the first product, there is an advantage in that a fair transaction can be provided by allowing the purchaser to transact with confidence that the first product is an item actually used by a celebrity.

[0167] FIG. 14 is a hardware configuration diagram of a computing system according to some embodiments of the present disclosure. The computing system (1000) of FIG. 14 may include one or more processors (1100), a system bus (1600), a communication interface (1200), a memory (1400) for loading a computer program (1500) executed by the processor (1100), and a storage (1300) for storing the computer program (1500).

[0168] The computing system (1000) of FIG. 14 may present a hardware structure of one or more computing systems constituting the service server (10) described with reference to FIG. 1, for example.

[0169] The processor (1100) controls the overall operation of each component of the computing system (1000). The processor (1100) can perform operations for at least one application or program for executing methods / operations according to various embodiments of the present disclosure. The memory (1400) stores various data, commands, and / or information. The memory (1400) can load one or more computer programs (1500) from the storage (1300) to execute methods / operations according to various embodiments of the present disclosure. The storage (1300) can non-temporarily store one or more computer programs (1500).

[0170] The computer program (1500) may include one or more instructions implementing methods / operations according to various embodiments of the present disclosure. When the computer program (1500) is loaded into the memory (1400), the processor (1100) may execute the one or more instructions to perform the methods / operations according to various embodiments of the present disclosure.

[0171] In one embodiment, the computer program (1500) may include instructions for performing an operation of receiving a request for authenticity verification for a first product from a seller terminal of a seller who wishes to sell the first product, an operation of generating appraisal information for the first product, an operation of transmitting an authenticity verification request including the appraisal information to a celebrity terminal that is a terminal of the original owner of the first product, an operation of receiving authentication information regarding the authenticity of the first product from the celebrity terminal as a response to the authenticity verification request, and an operation of accumulating a portion of the sales proceeds of the first product to the account of the original owner.

[0172] In one embodiment, the computer program (1500) may further include instructions for performing an operation of accumulating a portion of the sales proceeds of the first product to the seller's account when authentication information that the first product is genuine is received from the celebrity terminal.

[0173] Hereinafter, with reference to FIG. 15, the configuration and operation of an item ownership management system according to some embodiments of the present disclosure will be described. FIG. 15 is a system configuration diagram for explaining the configuration and operation of an item ownership management system according to some embodiments of the present disclosure.

[0174] Referring to FIG. 15, the product ownership management system may include a service server (10), a seller terminal (11), a buyer terminal (12), and a blockchain network (13). However, the scope of the present disclosure is not limited thereto. In some cases, the product ownership management system may be configured to further include modules / devices / systems not illustrated in FIG. 15. Alternatively, the product ownership management system may be configured to exclude at least some of the components (10 to 13) illustrated in FIG. 15.

[0175] The service server (10) may be a server that provides resources related to a used goods transaction service operated by an entity operating a used goods transaction platform. In response to a request for ownership transfer for an item from a seller terminal (11) of a seller seeking to sell an item used by a celebrity, the service server (10) may perform a prescribed ownership transfer process, thereby transferring ownership of the item from the seller to the buyer.

[0176] The service server (10) can perform an authentication process to determine whether the item is genuine and actually used by a celebrity, by referencing a registration transaction (see FIG. 16) recorded in a blockchain node on the blockchain network. The authentication process is described in detail with reference to FIGS. 19 to 24.

[0177] Based on the result of the authentication process, the service server (10) may transmit a buyer identification information input request to the seller terminal (11) requesting the input of the buyer's identification information to transfer the ownership of the item actually used by the celebrity. If, as a result of the authentication process, the item the seller wishes to sell is an item actually used by the celebrity, the service server (10) may transmit a buyer identification information input request to the seller terminal (11) to transfer the ownership of the item the seller wishes to sell. On the other hand, if, as a result of the authentication process, the item the seller wishes to sell is not an item actually used by the celebrity, the service server (10) may transmit a notification of this fact to the seller terminal (10) and may not record the transaction record regarding the item actually used by the celebrity in the transaction transaction (see FIG. 17). This will be described in detail with reference to FIG. 25.

[0178] When the service server (10) receives the buyer's identification information from the seller terminal (11), it can send a request for confirmation of ownership transfer to the buyer terminal (12) corresponding to the buyer's identification information, confirming whether the seller has received the item to which the seller wishes to transfer ownership. When the service server (10) receives a response confirming the transfer of ownership of the item from the buyer terminal (12) in response to the confirmation of ownership transfer, the service server (10) can record the ownership transfer details for the item in the transaction transaction (see FIG. 17) of the item recorded in the blockchain node on the blockchain network (13). As a result, the ownership of the item can be definitively transferred from the seller to the buyer. This will be described in detail with reference to FIGS. 26 and 27.

[0179] The seller terminal (11) may be a terminal of a seller seeking to sell items used by a celebrity. The seller terminal (11) may be a terminal of a seller using a second-hand transaction platform operated by the operator of the service server (10). The seller terminal (11) may transmit to the service server (10) a request for transfer of ownership of the item, the scan results of the item identification chip embedded in the item, and the identification information of the buyer seeking to transfer ownership of the item.

[0180] The buyer terminal (12) may be a terminal of a buyer who has purchased an item used by a celebrity from a seller. The buyer terminal (12) may be a terminal of a buyer using a second-hand transaction platform serviced by the operator of the service server (10). In this case, the buyer terminal (12) may transmit a response confirming the transfer of ownership of the item (= a response confirming the transfer of ownership of the item) to the service server (10) in response to a request for confirmation of ownership transfer received from the service server (10).

[0181] Meanwhile, the buyer terminal (12) may be a terminal of a buyer who does not use the second-hand transaction platform serviced by the operator of the service server (10). In this case, the purchase may be made through a private contract between the seller and the buyer, not through the second-hand transaction platform serviced by the operator of the service server (10). The service server (10) may transmit installation guidance content for the second-hand transaction platform to the buyer terminal (12). In this case, after installing the second-hand transaction platform, the buyer terminal (12) may respond to the ownership transfer confirmation request sent by the service server (10) only through the second-hand transaction platform. In this case, instead of providing the buyer with a certificate of authenticity and ownership change information regarding the second-hand transaction of an item used by a celebrity, the buyer may be encouraged to install and use the second-hand transaction platform. Therefore, there is an advantage in that the number of users of the second-hand transaction platform can be increased.

[0182] A blockchain network (13) may refer to a network formed by multiple blockchain nodes. Multiple blockchain nodes may share the same blockchain. Sharing the same blockchain here may mean that each blockchain node maintains a blockchain in which the same data is recorded through a consensus algorithm. The blockchain network (13) may record various data received from the service server (10) on the blockchain and may ensure the integrity of the data recorded through the blockchain. Those skilled in the art are likely already familiar with the operation of blockchain nodes and the principles of blockchain, and therefore, a detailed description thereof will be omitted.

[0183] Meanwhile, in some embodiments, components (10 to 13) of the celebrity-related item authentication system may communicate via a network. Here, the network may be implemented as any type of wired / wireless network, such as a Local Area Network (LAN), a Wide Area Network (WAN), a mobile radio communication network, or Wibro (Wireless Broadband Internet).

[0184] For ease of understanding, the following description assumes that all steps / operations of the methods described below are performed on the aforementioned service server (10). Therefore, if the subject of a specific step / operation is omitted, it can be understood that it is performed on the service server (10). However, in an actual environment, some steps / operations of the methods described below may be performed on other computing devices.

[0185] Hereinafter, with reference to FIGS. 16 and 17, a description will be given of transactions recorded in the process of managing ownership of goods by the service server (10) using blockchain technology.

[0186] FIG. 16 is a diagram illustrating a registration transaction of an item recorded on a blockchain within a blockchain network, referenced in some embodiments of the present disclosure.

[0187] Referring to FIG. 16, a registration transaction (20) for an item recorded on a blockchain is illustrated. The registration transaction (20) may include unique identification information (21) for the item, item characteristic data (22), celebrity information (23), and transaction records (24). However, the scope of the present disclosure is not limited thereto, and in some cases, it may be configured to include additional information not shown in FIG. 16.

[0188] A registration transaction (20) may be a transaction initially performed by a service provider through the service server (10) when a celebrity sells an item he or she used through the service provider through the service server (10). Items registered according to the registration transaction (20) may be maintained and managed by the service server (10).

[0189] The unique identification information (21) may be unique identification information identified through an item identification chip embedded in the item to distinguish that the item was used by the celebrity when the celebrity sold the item through a service provider that provides services via the service server (10). The service server (10) may retrieve information related to the unique identification information (21) on the blockchain within the blockchain network (13) to obtain item characteristic data related to the unique identification information of the item.

[0190] The product characteristic data (22) may include information about the characteristics of an item used by a celebrity. The product characteristic data (22) may include multiple (characteristic, value) data. For example, assume that the item used by the celebrity is a luxury bag, the first characteristic is a logo type, and that there are logo types from the first to the tenth logo types, each with a distinct shape. The logo type of the first item may be the fourth logo type. In this case, the product characteristic data for the first characteristic may include (logo type, fourth type) data.

[0191] Celebrity information (23) may be information containing personal information such as the name of a celebrity who used the product.

[0192] Transaction records (24) may be records of goods traded. Transaction records (24) may be continuously generated through the resale of goods. Therefore, transaction records (24) may include multiple transaction records. Transaction records (24) may be generated by a transaction of goods recorded on a blockchain. Transactions of goods may be recorded on a blockchain within a blockchain network (13).

[0193] Hereinafter, a transaction record (24) will be described with reference to FIG. 17. FIG. 21 is a diagram illustrating a transaction of goods recorded on a blockchain within a blockchain network, as referenced in some embodiments of the present disclosure.

[0194] Referring to Figure 17, a transaction (24) of goods recorded on a blockchain is illustrated.

[0195] Each transaction record or transaction transaction (24) may include information about the transaction hash value, TxnHash, status information regarding whether the transaction was successfully concluded, timestamp information regarding the time the transaction was concluded, information about From where the seller's wallet ID or identification information is recorded, information about To where the buyer's wallet ID or identification information is recorded, information about Value where the price of the item that is the subject of the transaction is recorded, information about Transaction Fee where the transaction fee is recorded, and information about a unique ID that can identify the traded item. However, the present disclosure is not limited thereto, and in some cases, the transaction transaction (54) may include other information. For example, when trading an item, authentication information may also be included where the celebrity who is the original owner of the item certifies that the item was used by him / her.

[0196] Hereinafter, the general operation of a method for managing ownership of an article according to some embodiments of the present disclosure will be described with reference to FIG. 18. FIG. 18 is a signal flow diagram illustrating the general operation of a method for managing ownership of an article according to some embodiments of the present disclosure.

[0197] Referring to Fig. 18, the seller terminal (11) can transmit a request for transfer of ownership of the first product to be sold to the service server (10) (S1000).

[0198] Hereinafter, step S1000 will be further described with reference to FIGS. 19 and 20. FIG. 19 is an exemplary diagram of a certificate list screen for items displayed on a seller terminal according to some embodiments of the present disclosure. FIG. 20 is an exemplary diagram of a certificate screen for a specific item displayed on a seller terminal according to some embodiments of the present disclosure.

[0199] Referring to FIG. 19, a certificate list screen for items displayed on a seller terminal (11) is illustrated. Referring to the certificate list screen, certificates for various items owned by the seller are listed. Regarding the item at the top, a representative thumbnail (50) of the first item the seller intends to sell, the certificate issuance date (51), the certificate title (52) based on the product name of the first item, and the certificate status (53) for the first item are illustrated.

[0200] The certificate status (53) may indicate the validity of the certificate for the product. The certificate status (53) may be "certificate valid" if the seller owns the certificate. The certificate status (53) may be "transfer request in progress" if the product is in the process of being transferred from the seller to the buyer, indicating that a certificate transfer request for the product is in progress. The certificate status (53) may be "receipt confirmation in progress" if the product has been transferred from the seller to the buyer and the buyer is confirming receipt of the certificate for the product.

[0201] When a seller clicks the certificate status (53) on the certificate list screen of an item displayed on the seller terminal (11), a certificate screen for a specific item as shown in Fig. 20 may be displayed on the seller terminal (11).

[0202] Referring to FIG. 20, a certificate screen for a first product displayed on a seller terminal is illustrated. The certificate screen for the first product may include a product image (60), product name (63), product information (64), and product description (65) for the first product.

[0203] Product information (64) may include information about the unique identification number stored in the registration transaction of the first product, the first owner of the first product (e.g., in the case of products used by a celebrity, the first person to purchase the first product from the celebrity), the date of issuance of the certificate for the first product, and the current owner (e.g., the seller in this disclosure).

[0204] Product description (65) is a brief description of the first product, and may include, for example, a description and image of information about a specific celebrity actually using the first product.

[0205] When the seller clicks the directional button (61, 62) displayed in the product image (60) field, he / she can check an actual photograph corresponding to the characteristics of the product characteristic data for the first product recorded in the registration transaction of the first product.

[0206] When a seller clicks the transaction history confirmation button (66) displayed on the seller terminal (11), the transaction history for the first item can be confirmed. The transaction history for the first item may be based on information recorded in the registration transaction and transaction transaction for the first item recorded on the blockchain node of the blockchain network (13).

[0207] When the seller clicks the ownership transfer button (66) displayed on the seller terminal (11), the seller terminal (11) can transmit a request for ownership transfer for the first item to the service server (10). When the seller clicks the ownership transfer button (66) displayed on the seller terminal (11), a screen representing the ownership transfer process illustrated in FIG. 21 can be displayed on the seller terminal (11).

[0208] Hereinafter, with reference to FIG. 21, the ownership transfer process received from the seller terminal (11) will be described in detail. FIG. 21 is an exemplary diagram of a screen showing the ownership transfer process displayed on the seller terminal according to some embodiments of the present disclosure.

[0209] Referring to Figure 21, the operations that must be performed to transfer ownership of the first article are illustrated.

[0210] The product verification process (70) may be a process of scanning an product identification chip embedded in a first product. If the first product is traded on a second-hand transaction platform operated by the operator of the service server (10), the operator of the service server (10) may pre-install an product identification chip capable of identifying the first product in the first product. The product identification chip may be a QR code or an NFC (Near Field Communication) chip. However, the scope of the present disclosure is not limited thereto, and any type of chip or recognition means may be used as long as the product identification chip can be recognized and the recognized information transmitted to the service server (10) when the seller tags or scans the seller terminal (11) in close proximity to the product identification chip. When the seller clicks the product verification process (70), a pop-up screen may be displayed on the seller terminal (11) guiding the scanning of the product identification chip embedded in the first product. The detailed operation of the product verification process (70) is described in detail with reference to FIG. 22.

[0211] The product appraisal process (71) may be a process for assessing whether the unique characteristics of the first item are maintained. The unique characteristics of the first item, i.e., the product characteristic data, may be recorded in the registration transaction for the first item described above. Specifically, the product characteristic data may include information about the characteristics of items used by celebrities. The product characteristic data may include multiple (characteristic, value) data. When a seller clicks the product appraisal process (71), a screen guiding the product appraisal may be displayed on the seller terminal (11). The detailed operations of the product appraisal process (71) will be described in detail with reference to FIGS. 23 and 24.

[0212] The recipient information input process (72) may be a process in which the seller inputs the identification information of the buyer to whom the seller wishes to transfer ownership of the first item. When the seller clicks the recipient information input process (72), a screen for entering recipient information may be displayed on the seller terminal (11). This will be described in detail with reference to FIG. 25.

[0213] The ownership transfer application process (73) may be a process in which the seller transmits a request for ownership transfer of the first item to the service server (10). When the seller terminal (11) transmits a request for ownership transfer to the service server (10), the status of the ownership transfer application process (73) may be a 'request' status.

[0214] Meanwhile, each process (70, 71, 72) may be displayed as a 'completed' state if the authentication or the task to be performed for the process has been completed. On the other hand, each process (70, 71, 72) may be displayed as an 'incomplete' state (74) if the authentication or the task to be performed for the process has not been completed.

[0215] Again, this is explained with reference to Fig. 18.

[0216] When the service server (10) receives a request for transfer of ownership of the first item (S1000), the service server (10) can transmit a scan request of the item identification chip embedded in the first item to the seller terminal (11) (S2000). The seller can scan the item identification chip embedded in the first item using the seller terminal (11). As described above, when the first item is traded on a second-hand transaction platform operated by the operator of the service server (10), the operator of the service server (10) can pre-install an item identification chip capable of identifying the first item as the first item. The item identification chip may be a QR code or an NFC (Near Field Communication) chip.

[0217] Thereafter, the seller terminal (11) can transmit the scan result of the product identification chip in response to the scan request to the service server (10) (S3000).

[0218] Hereinafter, the process for a scan request described in S2000 and S3000 will be described with reference to FIG. 22. FIG. 22 is an exemplary diagram illustrating a screen indicating a scan request for an item identification chip displayed on a seller terminal according to some embodiments of the present disclosure.

[0219] Referring to Fig. 22, a scan request page is illustrated. When a seller clicks the product confirmation process (70) on the screen of Fig. 21, a pop-up screen (80) may be displayed on the seller terminal (11) guiding the seller to scan the product identification chip embedded in the first product.

[0220] The pop-up screen (80) may include a GIF message that prompts the seller terminal (11) to tag the product identification chip of the first product. By tagging the seller terminal (11) with the product identification chip of the first product, the seller can scan the product identification chip embedded in the first product.

[0221] Meanwhile, the seller can close the pop-up screen (80) by clicking the cancel button (82) displayed on the pop-up screen (80).

[0222] Again, this is explained with reference to Fig. 18.

[0223] When a scan result of the product identification chip embedded in the first product is received in response to a scan request for the product identification chip (S3000), the service server (10) may transmit a buyer identification information input request to the seller terminal (11) based on the scan result, requesting the input of the buyer's identification information to transfer the ownership of the first product (S4000). The seller may input the buyer's identification information through the seller terminal (11). The buyer's identification information may be the buyer's representative phone number. However, the scope of the present disclosure is not limited thereto, and the buyer's identification information may be in any form as long as it can identify the buyer. This will be described in detail with reference to FIG. 25.

[0224] Afterwards, the seller terminal (11) can transmit the buyer's identification information entered by the seller to the service server (10) (S5000).

[0225] Thereafter, the service server (10) may transmit a request for confirmation of ownership transfer to the purchaser terminal (12) corresponding to the received purchaser identification information, confirming whether ownership of the first item has been transferred (S6000). The request for confirmation of ownership transfer may confirm whether the purchaser has transferred possession of the first item from the seller and acquired ownership of the first item from the seller. This will be described in detail with reference to FIGS. 26 and 27.

[0226] The buyer can write a response to the request for confirmation of ownership transfer via the buyer terminal (12). The buyer terminal (12) can then transmit the response to the request for confirmation of ownership transfer to the service server (10) (S7000). The response to the request for confirmation of ownership transfer may be a response confirming the transfer of ownership of the first item or a response rejecting the transfer of ownership of the first item.

[0227] Thereafter, based on the response to the request for confirmation of ownership transfer, the service server (10) can record the ownership transfer for the first item in the transaction transaction for the first item recorded in the blockchain node on the blockchain network (13) (S8000). That is, the service server (10) can record the transfer of ownership for the first item from the seller to the buyer in the transaction transaction for the first item recorded in the blockchain node on the blockchain network (13). Therefore, by recording the ownership for the first item in the blockchain node, data integrity regarding the ownership transfer can be guaranteed.

[0228] According to this embodiment, a seller can perform a verification process to determine whether the item they are selling has actually been used by a celebrity. Based on the results, the ownership transfer status of the item can be recorded on a blockchain node. Therefore, this embodiment can effectively ensure transaction security in the second-hand trading of items actually used by celebrities.

[0229] Hereinafter, the product appraisal process (71) illustrated in FIG. 21 will be described in detail with reference to FIG. 23. FIG. 23 is a detailed flowchart illustrating the detailed operations of the method for managing ownership of goods according to some embodiments of the present disclosure, as described with reference to FIG. 18.

[0230] The service server (10) can determine whether the identification information of the first article, identified based on the scan result of the article identification chip embedded in the first article, matches the unique identification information stored in the registration transaction of the genuine article corresponding to the first article (S3100). The identification information of the first article may be an NFC serial number recognized through tagging between the seller terminal (11) and the article identification chip of the first article. The genuine article may be an article actually used by a celebrity, and may be a product that was first recorded in a blockchain node and sold by the operating entity operating the service server (10).

[0231] If the S3100 judgment result shows that the identification information of the first product and the unique identification information of the genuine product do not match, the service server (10) may send a message to the seller terminal (11) informing that the transfer of ownership of the genuine product is not possible, and terminate the process of transferring ownership of the first product.

[0232] On the other hand, if the determination result of S3100 is that the identification information of the first article matches the unique identification information of the genuine article, the service server (10) can retrieve the article characteristic data related to the unique identification information of the genuine article (S3200). The article characteristic data is data included in the registration transaction of the genuine article recorded in the blockchain node on the blockchain network (13) and may include multiple (characteristic, value) data. Since all registration transactions and transaction transactions for the first article are recorded in the blockchain node on the blockchain network (13), the service server (10) can always retrieve the transaction records and article characteristic data for the first article.

[0233] Thereafter, the service server (10) can transmit a request for transmission of a photograph taken of the characteristics included in the product characteristic data for the first product to the seller terminal (11) (S3300).

[0234] When the service server (10) receives a photograph of a characteristic included in the product characteristic data for the first product as a response to the transmission request from the seller terminal (11) (S3400), the service server (10) can compare the received photograph with image data corresponding to the characteristic included in the product characteristic data (S3500). The service server (10) can determine whether the photograph of the first product and the image data taken at the time of registration of the genuine product match by comparing the photograph of the first product with the photograph taken at the time of registration of the genuine product using an artificial intelligence-based image recognition deep learning model (S3500). The service server (10) can determine whether the first product and the genuine product are identical by comparing the photograph of the first product with the photograph taken at the time of registration of the genuine product.

[0235] If the judgment result of S3500 is that the photograph of the first product and the image data taken at the time of registration of the genuine product do not match, the service server (10) can send a message to the seller terminal (11) requesting a request from the customer center or a message requesting re-photography of the first product, and terminate the ownership transfer process for the seller's ownership transfer request.

[0236] If the judgment result of S3500 is that the photograph of the first item matches the image data taken when registering the authenticity, the service server (10) may transmit a buyer identification information input request to the seller terminal (11) requesting the input of identification information of the buyer who wishes to transfer ownership of the first item (S4000). In other words, step S4000 may be performed only when the first item is certified as authentic.

[0237] According to this embodiment, the stability of second-hand transactions for items used by celebrities can be guaranteed by performing a process to verify whether the item the seller wants to sell is genuine.

[0238] Hereinafter, the embodiment described with reference to FIG. 23 will be described in more detail with reference to FIG. 24. FIG. 24 is an exemplary diagram of a screen indicating a request for transmission of a photograph of an item displayed on a seller terminal according to some embodiments of the present disclosure.

[0239] Referring to FIG. 24, the service server (10) can use an artificial intelligence-based image recognition deep learning model to compare a photograph (240) taken at the time of registration of a genuine product with a photograph (242) taken of the first product. Using the result of the comparison, the service server (10) can determine whether the photograph of the first product and the image data taken at the time of registration of the genuine product match (243). If the determination result shows that the photograph of the first product and the image data taken at the time of registration of the genuine product do not match, a notification may be displayed on the screen of the seller terminal (11) indicating that the photograph of the first product and the image data taken at the time of registration of the genuine product do not match. If the determination result shows that the photograph of the first product and the image data taken at the time of registration of the genuine product match, a notification may be displayed on the screen of the seller terminal (11) indicating that the photograph of the first product and the image data taken at the time of registration of the genuine product match.

[0240] The seller takes a picture of the first product using the camera mounted on the seller terminal (11), and the picture of the first product can be displayed at the bottom of the screen of the seller terminal (11) (241).

[0241] By clicking the directional button (244, 245), the seller can request or confirm a determination of whether the image corresponding to multiple product characteristic data related to the unique identification information of the genuine article matches the photograph of the first article. The seller terminal (11) screen may include a determination data count (246) that can confirm the number and order of product characteristic data.

[0242] Hereinafter, with reference to FIG. 25, a request for inputting buyer identification information according to some embodiments of the present disclosure will be described. FIG. 25 is an exemplary diagram illustrating a screen representing a request for inputting buyer identification information according to some embodiments of the present disclosure.

[0243] Referring to Figure 25, the seller can enter the identification information (250) of the buyer (recipient) to whom the ownership of the first item is to be transferred. The seller can enter the buyer's identification information (250), such as the buyer's phone number, and click the "Search" button (251).

[0244] When the service server (10) searches for the buyer's identification information (250), if the buyer is a member of a second-hand transaction platform operated by the operator of the service server (10), the service server (10) can display the buyer's ID information (252) existing on the second-hand transaction platform. The seller can confirm the buyer by clicking the 'Confirm' button (253). Meanwhile, if the searched buyer's ID information (252) is not the ID of the buyer who wishes to transfer the ownership of the first item, the seller can search again for the ID of the buyer who wishes to transfer the ownership of the first item by clicking the 'Re-Search' button (254).

[0245] On the other hand, there may be a case where the seller accurately enters the buyer's phone number and clicks the 'Search' button (251), but the buyer is not a member of the second-hand transaction platform operated by the operator of the service server (10). In this case, the service server (10) may transmit membership inducing content to the buyer's terminal (12) corresponding to the buyer's phone number entered by the seller, inducing membership in the second-hand transaction platform. The service server (10) may transmit the membership inducing content by sending an SMS message to the buyer's terminal (12). For example, the SMS message may send a message inviting the buyer to become a member of the second-hand transaction platform in order to obtain an official certificate of authenticity of the first article, along with a link for installing the second-hand transaction platform.

[0246] The above-mentioned membership registration inducement content may include content regarding a certificate of authenticity for the first item that the seller wishes to transfer to the buyer and information regarding a change in ownership of the first item. The certificate of authenticity may be in the form illustrated in FIG. 20. The information regarding the change in ownership of the first item may be a notice informing the buyer that if they sign up for the second-hand trading platform, the current owner recorded on the certificate of authenticity of the first item will change from the seller to the buyer.

[0247] In this case, the response to the request for confirmation of transfer of ownership to confirm whether or not the ownership of the first item has been transferred can only be performed on the second-hand transaction platform by the buyer registering as a member on the second-hand transaction platform.

[0248] According to this embodiment, if the buyer is not a member of the secondhand trading platform operated by the operator of the service server (10), the buyer can be registered on the secondhand trading platform instead of providing the buyer with a certificate of authenticity for the first item and a method for proving ownership transfer status. Therefore, this embodiment has the effect of increasing the number of users of the secondhand trading platform.

[0249] Below, with reference to FIG. 27, a process for requesting and responding to a confirmation of ownership transfer is described. FIG. 27 is an exemplary diagram illustrating a screen displaying a request for confirmation of ownership transfer of an item displayed on a purchaser's terminal according to some embodiments of the present disclosure.

[0250] Referring to Figure 27, a screen identical to the certificate screen for the item illustrated in Figure 20 is illustrated. With respect to the current owner information (120) regarding the item, it may be indicated that the transfer of ownership of the item is in progress until the purchaser responds to the request for confirmation of ownership transfer and the service server (10) receives the response.

[0251] The buyer can respond to the request for confirmation of ownership transfer by clicking the "Accept Ownership" button (121). When the buyer clicks the "Accept Ownership" button (121), a screen related to the ownership transfer process, as illustrated in FIG. 27, may be displayed.

[0252] Below, the ownership transfer process is described with reference to FIG. 27. FIG. 27 is an exemplary diagram of a screen indicating a request for confirmation of ownership transfer of an item displayed on a purchaser terminal according to some embodiments of the present disclosure.

[0253] Referring to Figure 27, the tasks that must be performed to confirm the transfer of ownership are illustrated.

[0254] The product verification process (270) may be a process of scanning an product identification chip embedded in a first product. If the first product is traded on a second-hand trading platform operated by the operator of the service server (10), the operator of the service server (10) may pre-install an product identification chip capable of identifying the first product in the first product. The product identification chip may be a QR code or an NFC (Near Field Communication) chip. However, the scope of the present disclosure is not limited thereto, and any type of chip or recognition means may be used as long as the product identification chip can be recognized and the recognized information transmitted to the service server (10) when the buyer tags or scans the buyer terminal (12) in close proximity to the product identification chip. When the buyer clicks the product verification process (270), a pop-up screen may be displayed on the buyer terminal (12) guiding the buyer to scan the product identification chip embedded in the first product. The detailed operation of the product verification process (270) is as described with reference to FIG. 22.

[0255] The product appraisal process (271) may be a process for assessing whether the unique characteristics of the first item are maintained. The unique characteristics of the first item, i.e., the product characteristic data, may be recorded in the registration transaction for the first item described above. Specifically, the product characteristic data may include information about the characteristics of items used by celebrities. The product characteristic data may include multiple (characteristic, value) data. When a buyer clicks the product appraisal process (271), a screen guiding the product appraisal may be displayed on the buyer terminal (12). The detailed operations of the product appraisal process (271) are as described with reference to FIGS. 23 and 24 .

[0256] The ownership acquisition process (272) is a process that can perform a response confirming the transfer of ownership of the first item. When the buyer clicks the ownership acquisition process (272), a pop-up screen (not shown) may be displayed asking the buyer to confirm whether to definitively transfer ownership of the first item. By clicking "Confirm ownership transfer" displayed on the pop-up screen, the buyer can definitively transfer ownership of the first item from the seller to the buyer. If ownership of the first item is definitively transferred from the seller to the buyer, a "Confirmed" status (274) may be displayed for the ownership acquisition process (272).

[0257] Meanwhile, each process (270, 271, 272) may be displayed as a 'completed' state if the authentication for the process or the task to be performed has been completed. On the other hand, each process (270, 271, 272) may be displayed as an 'incomplete' state (273) if the authentication for the process or the task to be performed has not been completed.

[0258] According to this embodiment, the authenticity of the first item can be guaranteed by both the seller and buyer performing the product verification and appraisal processes. Therefore, this embodiment has the effect of improving transaction security for the first item.

[0259] Meanwhile, in one embodiment, if a response confirming the transfer of ownership of the first item is received in response to a request for confirmation of ownership transfer to confirm whether or not the ownership of the first item has been transferred, the service server (10) may take measures to prevent the display of authenticity authentication information of the first item when the seller terminal (11) scans the item identification chip embedded in the first item. In this case, for example, if seller ID information is obtained on a second-hand transaction platform serviced by the operating entity operating the service server (10) through NFC tagging, the service server (10) may set the seller terminal (11) to prevent the display of the authenticity authentication information of the first item. However, the scope of the present disclosure is not limited thereto, and various forms of measures may be performed.

[0260] According to this embodiment, if ownership of an authentic item has been definitively transferred from the seller to the buyer, the seller can prevent cases where a counterfeit item is disguised as genuine by attaching an identical product identification chip to the counterfeit item and scanning it. Therefore, this embodiment can have the effect of improving the security of transactions for items actually used by celebrities.

[0261] Meanwhile, in one embodiment, there may be a case where the service server (10) repeatedly transmits multiple ownership transfer confirmation requests to the purchaser terminal (12) according to a preset cycle a preset number of times (e.g., once a day), but no response is received from the purchaser terminal (12) to all of the multiple ownership transfer confirmation requests. That is, there may be a case where the service server (10) repeatedly transmits ownership transfer confirmation requests, but the purchaser does not take any action.

[0262] In this case, to prevent a situation of absence of ownership of the first item and thus incomplete ownership information, the service server (10) may record a deregistration transaction for the first item in a blockchain node on the blockchain network (13). The deregistration transaction may be recorded in the transaction record (24) of the registration transaction (20). The deregistration transaction may be a transaction that includes information regarding a situation in which a transfer of ownership of the first item was requested, but the buyer did not respond to a request for confirmation of the transfer of ownership.

[0269] In some embodiments of the present disclosure, the item identifier may be obtained as a result of the user terminal (282) performing short-range wireless communication with the micro storage device (283-1) of the first item (283).

[0270] In some other embodiments of the present disclosure, the short-range wireless communication may be, but is not limited to, any one of Wi-Fi, Bluetooth, Near Field Communication (NFC), and Zigbee.

[0271] According to another embodiment of the present disclosure, the product transaction service server (280) can use the product identifier included in the certificate provision request to search for the current owner of the first product (283) corresponding to the product identifier in the product transaction history data.

[0272] A product transaction history server (281) according to one embodiment of the present disclosure may be a server that stores history information of each transaction through a used product transaction service served by a product transaction service server (280).

[0273] In some embodiments of the present disclosure, the product transaction service server (280) may transmit a request to the product transaction history server (281) to inquire about information related to the product identifier and the current owner of the first product (283), and may obtain the ID of the purchaser of the last transaction of the first product (283) from the product transaction history server (281).

[0274] In some other embodiments of the present disclosure, the product transaction history server (281) may be a storage system that stores the transaction history for the first product (283) in the form of a transaction in a blockchain network.

[0275] According to another embodiment of the present disclosure, the product transaction service server (280) can determine whether the current owner and the user of the user terminal (282) are matched.

[0276] In some embodiments of the present disclosure, the product transaction service server (280) may determine whether the current owner of the first product (283) and the user of the user terminal (282) correspond based on the result of comparing the ID of the purchaser of the last transaction of the first product (283) received from the product transaction history server (281) and the ID of the user of the user terminal (282) that sent the request for providing a certificate for the first product (283).

[0277] According to another embodiment of the present disclosure, the product transaction service server (280) may transmit data of a certificate corresponding to the product identifier of the first product (283) to the user terminal (282) based on a determination that the current owner of the first product (283) and the user of the user terminal (282) correspond to each other.

[0283] Additionally, the method for authenticating and trading celebrity-related items according to the present embodiment may be performed by one or more computing systems. Furthermore, the method for authenticating and trading celebrity-related items according to the present embodiment may perform some operations by a first computing device, while the remaining operations may be performed by a second computing device. For example, some operations of the method for authenticating and trading celebrity-related items according to the present embodiment may be performed by an on-premise physical server, while the remaining operations may be performed by a cloud compute instance. Furthermore, for example, some operations of the method for authenticating and trading celebrity-related items according to the present embodiment may be performed by a product transaction service server, while the remaining operations may be performed by a user terminal. Hereinafter, if the entity performing each operation is omitted, it will be understood that the entity performing the operation is the computing system.

[0284] FIG. 29 is a flowchart of a method for providing a product certificate according to another embodiment of the present disclosure.

[0285] FIG. 30 is a sequence diagram of a method for providing a product certificate according to another embodiment of the present disclosure.

[0286] In step S10 illustrated in FIG. 30, the user terminal (282) performs NFC (Near Field Communication) reading on the micro storage device (283-1) of the first article (283), and in step S11, as a result of performing the NFC reading, the article identifier of the first article (283) can be received from the micro storage device (283-1) of the first article (283).

[0287] In some embodiments related to step S11, the product identifier of the first product (283) may mean identification information for specifying the first product (283) among a plurality of products stored in the product transaction history server (281).

[0288] In step S2900 illustrated in FIGS. 29 and 30, the product transaction service server (280) may receive a request for provision of a certificate including a product identifier of the first product (283) from a user terminal (282).

[0289] For example, referring to FIG. 31, the user terminal (282) may obtain an item identifier of the first item (283) stored in the micro storage device (283-1) of the first item (283) as a result of performing short-range wireless communication with the micro storage device (283-1) of the first item (283). In addition, the user terminal (282) may transmit a request for providing a certificate including the item identifier of the first item (283) to the item transaction service server (280). This may be understood as a request specifying that a certificate for the first item (283) be provided among the item identifiers for each of the plurality of items stored in the item transaction service server (280).

[0290] In step S2910 illustrated in FIG. 29, the product transaction service server (280) can search for the current owner of the first product (283) corresponding to the product identifier in the product transaction history data.

[0291] Step S2910 is described in detail with reference to FIGS. 30 and 32.

[0292] Steps S2911 and S2912 illustrated in FIG. 30 may be understood as being part of step S2910.

[0293] In step S2911 illustrated in FIG. 30, when the product transaction service server (280) receives a request for providing a certificate including the product identifier of the first product (283) from the user terminal (282), it can transmit a request to the product transaction history server (281) to inquire about the current owner of the first product (283).

[0294] In some embodiments related to step S2911, when the product transaction service server (280) receives a request for providing a certificate including a product identifier of the first product (283) from a user terminal (282), the product transaction service server (280) may transmit a request to the product transaction history server (281) to transmit a transaction history related to the first product (283).

[0295] In step S2912, the goods transaction service server (280) can receive the ID of the purchaser of the last transaction of the first goods from the goods transaction history server (281).

[0296] In some embodiments related to step S2912, the product transaction service server (280) may determine the purchaser corresponding to the purchaser ID of the last transaction among multiple transactions corresponding to the product identifier of the first product (283) existing in the transaction history related to the first product (283) received in step S2911 as the current owner of the first product (283).

[0297] For example, referring to FIG. 32, the product transaction service server (280) may transmit a request to the product transaction history server (281) to search for the current owner of the first product (283), and the product transaction history server (281) may transmit the purchaser ID (322-1) of the fifth transaction (322), which is the most recent transaction existing in the first transaction table (321), which is product transaction history data corresponding to the product identifier of the first product (283), to the product transaction service server (280).

[0298] For another example, referring to FIG. 32, when the product transaction history server (281) receives a request for transmitting the transaction history of the first product (283) including the product identifier of the first product (283) from the product transaction service server (280), the product transaction service server (280) may transmit information of the first transaction table (321), which is product transaction history data corresponding to the product identifier of the first product (283), to the product transaction service server (280). In addition, the product transaction service server (280) may determine the fifth transaction (322), which is the most recent transaction existing in the first transaction table (321), as the last transaction for the first product (283), and determine the buyer corresponding to the buyer ID (322-1), which is buyer identification information of the fifth transaction (322), as the current owner of the first product (283).

[0299] Here, the seller identification information in the first transaction table (321) may be the user ID of the seller of each transaction existing in the first transaction table (321) on the used goods transaction service. In addition, the buyer identification information may be the user ID of the buyer of each transaction existing in the first transaction table (321) on the used goods transaction service.

[0300] According to this embodiment, the product transaction service server (280) can clearly record evidence of the authenticity of a product by recording the transaction history of a specific product, and can achieve the effect of preventing unfair ownership disputes of the specific product.

[0301] In step S2920 illustrated in FIG. 29, the product transaction service server (280) can determine whether the current owner searched in step S2910 and the user of the user terminal are the same.

[0302] In some embodiments related to step S2920, for example, referring to FIG. 32, the goods transaction service server (280) can determine whether the ID of the user terminal (282) that sent the request for providing a certificate for the first goods (283) logging in to the used goods transaction service matches the buyer ID (322-1) of the fifth transaction (322) of the first transaction table (321).

[0303] In step S2930-2 illustrated in FIGS. 29 and 30, if it is determined in step S2920 that the current owner of the first product (283) and the user of the user terminal (282) are the same person, the product transaction service server (280) can determine whether the difference between the timestamp of the first transaction corresponding to the product identifier of the first product (283) and the activation timestamp of the micro storage device (283-1) of the first product (283) is less than a reference value.

[0304] In some embodiments related to step S2930-2, the activation timestamp of the micro-storage device (283-1) of the first article (283) may mean time information when the micro-storage device (283-1) of the first article (283) was first activated. Here, the micro-storage device (283-1) of the first article (283) may be a device that is activated when at least one transaction for the first article (283) has been completed. In addition, the activation timestamp of the micro-storage device (283-1) of the first article (283) may be stored in the micro-storage device (283-1) of the first article (283), but in some other embodiments, the activation timestamp of the micro-storage device (283-1) of the first article (283) may be stored in the article transaction service server (280).

[0305] In some other embodiments related to step S2930-2, the activation timestamp of the micro storage device (283-1) of the first article (283) may mean a time within a reference value from the time when the micro storage device (283-1) of the first article (283) was first inserted into the first article (283).

[0306] In some other embodiments related to step S2930-2, the certificate provision request of step S2900 may be a request including an activation timestamp of the micro storage device (283-1) of the first article (283).

[0307] For example, referring to FIG. 33, when the time stamp validity standard is 30 minutes, the activation timestamp (283-1a) of the micro storage device (283-1) of the first item (283) is 23:15:30 on October 6, 2023, and the timestamp (331-1) of the first transaction (331), which is the first transaction of the first transaction table (321) of the first item (283), is 23:11:45 on October 6, 2023, the item transaction service server (280) activates the micro storage device (283-1) of the first item (283) because the time difference between the activation timestamp (283-1a) of the micro storage device (283-1) of the first item (283) and the timestamp (331-1) of the first transaction (331) is less than 30 minutes. The device (283-1) can be determined to be valid.

[0308] In the case of malicious users of the product transaction service, there is a risk of deceiving buyers by falsifying information stored in the micro-storage device, thereby making them believe they are the current owner of the first product (283). According to the present embodiment, the product transaction service server (280) can also achieve the effect of ensuring the validity of the micro-storage device included in each product by managing the activation timing of the micro-storage device.

[0309] In some other embodiments related to step S2930-2, the product transaction service server (280) may determine that the micro-storage device (283-1) of the first product (283) is a valid micro-storage device only when the difference in coordinates between the initial activation location of the micro-storage device (283-1) of the first product (283) and the location of the initial transaction related to the first product (283) is less than a threshold value.

[0310] Step S2930-1 is described with reference to FIGS. 29 and 30.

[0311] In some embodiments related to step S2930-1, if the product transaction service server (280) determines in step S2910 that the ID of the current owner of the first product (283) and the ID of the user of the user terminal (282) do not match, the product transaction service server (280) may display information about the current owner of the first product (283) on the screen through the interface of the used product transaction service of the user terminal (282).

[0312] According to this embodiment, if the user of the user terminal (282) is the last purchaser of the first product (283) but cannot obtain a certificate, the product transaction service server (280) can recognize that there was an error in the user's purchase of the first product (283).

[0313] In some other embodiments related to step S2930-1, if the product transaction service server (280) determines in step S2910 that the ID of the current owner of the first product (283) and the ID of the user of the user terminal (282) do not match, the product transaction service server (280) may transmit a notification message including the fact that a request for providing certificate information for the first product (283) was performed by the user of the user terminal (282) to the user terminal (not shown) of the current owner of the first product (283).

[0314] According to this embodiment, the product transaction service server (280) can achieve the effect of encouraging the current owner of the first product (283) to take appropriate action by notifying the current owner of the first product (283) that an attempt has been made to perform an abnormal transaction on the first product (283).

[0315] For example, referring to FIG. 34, when the user ID of the used goods transaction service logged into the user terminal (282) is 'qwdok221' and the buyer ID (322-1) of the fifth transaction (322), which is the last transaction in the first transaction table (321) of the first item (283), is 'sstt422', the item transaction service server (280) may transmit information including the buyer ID (322-1) of the fifth transaction (322) to the user terminal (282) and transmit a notification message to the user terminal (341) of the current owner of the first item (283) notifying that there has been an abnormal attempt to acquire a certificate by the user of the user terminal (282).

[0316] In one embodiment, the computer program (1500) may include instructions for performing the following operations: receiving a request for transferring ownership of the first article from a seller terminal of a seller who is the original owner of the first article; transmitting a request for scanning an article identification chip embedded in the first article to the seller terminal in response to receiving the request for transferring ownership; receiving, from the seller terminal, a scan result of the article identification chip in response to the scan request; transmitting, based on the scan result, a request for inputting buyer identification information requesting input of identification information of a buyer who wishes to transfer ownership of the first article to the seller terminal; receiving, from the seller terminal, the identification information of the buyer in response to the request for inputting the buyer identification information; transmitting, to the buyer terminal corresponding to the identification information of the buyer, a request for confirming ownership transfer to confirm whether or not ownership of the first article is to be transferred; receiving, from the buyer terminal, a response to the request for confirming ownership transfer; and recording, based on the response to the request for confirming ownership transfer, the details of the transfer of ownership of the first article in a transaction transaction of the first article recorded in a blockchain. there is.
