Description

{Server system and method for confirming the ownership of a work of art and transferring the ownership of the work of art according to the transaction of the work of art}

The present invention relates to a server system and method for confirming the owner of a work of art and transferring the owner of the work of art according to a transaction of the work of art, and more specifically, to a server system and method for confirming the owner of the work of art and transferring the owner of the work of art according to a transaction of the work of art, in which works of art are registered in a server system, an encryption serial number and a second key for each work of art are stored, a first key is received from an owner terminal that owns the work of art, and the encryption serial number is decrypted based on the first key and the second key to derive information on the owner of the work of art matching the serial number stored in a blockchain server, thereby authenticating the ownership of the work of art.

There are many fakes in art, so it is essential to verify ownership when trading. To verify ownership offline, documents such as certificates of authenticity and certificates of authenticity are used, or appraisals are conducted by experts. These documents can be forged, so there is a problem that they are not completely reliable, and there is a burden of additional costs associated with hiring experts.

Online, it is possible to verify ownership using blockchain technology. Blockchain is a technology that encrypts and stores transaction history on a distributed network, so transaction history stored on the blockchain cannot be altered or deleted, making it highly reliable. If the ownership of a work of art is registered on the blockchain, the buyer can verify through the blockchain whether the seller is actually the owner of the work of art. In addition, since the authenticity of the work of art is also recorded on the blockchain, it is possible to verify whether the work of art is authentic without an expert inspection.

Accordingly, there is a need for an invention that can more easily verify ownership and store transaction history online using blockchain technology to transfer ownership.

Meanwhile, Korean Patent Publication No. 10-2023-0040734 discloses a method for encrypting transaction history verification and ownership transfer based on blockchain using distributed computing, the method including the steps of generating a first asset block through a preset consensus node of a private blockchain based on first asset information, generating at least one token corresponding to a digital security based on the first asset block, distributing the at least one token to at least one initial investor, and registering the at least one token distributed to the at least one initial investor on an exchange node.

Figure 3 schematically illustrates an ownership authentication unit (1100) according to one embodiment of the present invention.

As illustrated in FIG. 3, the ownership authentication unit (1100) may perform a first information receiving step of deriving an encryption serial number for an artwork selected by an owner terminal (2000) and receiving a first key input from the owner terminal (2000); a first decryption step of deriving a second key matching the encryption serial number based on the encryption serial number received in the first information receiving step, and deriving a decryption serial number that decrypts the encryption serial number based on the first key received in the first information receiving step and the second key; and a first owner verification step of querying the decryption serial number from the external blockchain server (4000) to receive owner information for a serial number corresponding to the decryption serial number, and confirming whether the owner information matches the self-information received in the first information receiving step.

In the server system (1000), a plurality of works of art may be stored as registered works of art, and an encryption serial number and a second key for each of the plurality of registered works of art may be pre-stored in the server system (1000). That is, the encryption serial number and the second key for each of the plurality of works of art may be stored as a pair, matching each other.

The blockchain server (4000) may store serial numbers and owner information for each of a plurality of registered artworks. That is, the serial numbers and owner information for each of a plurality of registered artworks may be stored as a pair.

The ownership authentication unit (1100) included in the server system (1000) performs the first information receiving step, the first decryption step, and the first owner verification step, thereby enabling the owner to authenticate the ownership of the artwork he or she owns (registered artwork registered in the server system (1000)).

Specifically, the owner terminal (2000) can select a work of art through an application and input the first key. Accordingly, the owner authentication unit (1100) can receive, from the owner terminal (2000) in the first information receiving step, a pre-stored encryption serial number, a first key, and self-information about the user of the owner terminal (2000) (the owner of the work of art) according to the work of art.

The above self-information may correspond to information that can identify the owner, and may correspond to a form corresponding to owner information stored in an external blockchain server (4000).

In the first decryption step, the encryption serial number received from the owner terminal (2000) is searched to derive an encryption serial number matching the encryption serial number for a plurality of registered artworks stored in the server system (1000), and a second key matching the encryption serial number can be derived. The owner authentication unit (1100) can, based on the first key received from the owner terminal (2000) and the second key matching the encryption serial number received from the owner terminal (2000), decrypt the encryption serial number using the first key and the second key as decryption keys to derive the decryption serial number.

In the first owner verification step, the decryption serial derived in the first decryption step can be searched for in an external blockchain server (4000), and a serial corresponding to the decryption serial can be derived from among the serials pre-stored in the external blockchain server (4000), and the owner authentication unit (1100) can receive owner information stored matching the corresponding serial from the external blockchain server (4000). The owner authentication unit (1100) can determine whether the owner information received from the external blockchain server (4000) and the self-information received from the owner terminal (2000) match, and if the owner information and the self-information match, the owner can be authenticated as the user of the owner terminal (2000) for the corresponding artwork.

The art transaction section (1200) included in the server system (1000) performs the second information receiving step, the second decryption step, the second owner confirmation step, the initialization step, the setting receiving step, the matching step, and the information update step, so that the seller can transfer the ownership of the art piece he owns to the buyer. Details about this are described in FIG. 4 and FIG. 5.

FIG. 4 schematically illustrates the second information receiving step, the second decryption step, and the second owner verification step performed by the art transaction unit (1200) according to one embodiment of the present invention.

As illustrated in FIG. 4, the art transaction unit (1200) may perform a second information receiving step of receiving a first key input from a corresponding seller terminal (5000) that has registered the registered art piece for sale in a server system (1000), and self-information about the corresponding seller; a second decryption step of decrypting a pre-stored encryption serial number for the corresponding registered art piece based on the first key received in the second information receiving step and the pre-stored second key for the corresponding registered art piece, and deriving a decryption serial number; and a second owner verification step of checking the decryption serial number from the external blockchain server (4000) and receiving owner information about the serial number corresponding to the decryption serial number to confirm whether the owner information matches the self-information received in the second information receiving step.

As described above, a plurality of works of art may be registered as registered works of art in the server system (1000), and an encryption serial number and a second key for each of the plurality of registered works of art may be stored in advance. The encryption serial number and the second key for each of the plurality of registered works of art may be stored as a pair, matching each other.

The blockchain server (4000) may store serial numbers and owner information for each of a plurality of registered artworks. The serial numbers and owner information for each of a plurality of registered artworks may be stored as a pair.

A seller terminal (5000) can register a work of art (hereinafter referred to as a registered work of art) in a server system (1000) in order to sell the registered work of art it owns, and a buyer terminal (3000) can make a purchase request for the registered work of art on the server system (1000), and accordingly, the seller terminal (5000) can receive a sales request for the registered work of art from the server system (1000).

When a registered work of art is delivered by a seller, the seller can first authenticate ownership of the registered work of art to the server system (1000) in order to transfer ownership of the registered work of art. That is, ownership of the registered work of art can be authenticated to the server system (1000) using the seller terminal (5000).

The registered artwork can be selected through an application at the seller terminal (5000) and the first key can be entered. Accordingly, the artwork transaction department (1200) can receive the first key and self-information about the user of the seller terminal (5000) (owner of the registered artwork) from the seller terminal (5000) in the second information receiving step, and can derive an encrypted serial number for the registered artwork.

The above self-information may correspond to information that can identify the owner, and may correspond to a form corresponding to owner information stored in an external blockchain server (4000).

In the second decryption step, the encryption serial number received from the seller terminal (5000) can be searched to derive an encryption serial number matching the encryption serial number for a plurality of registered artworks stored in the server system (1000), and a second key matching the encryption serial number can be derived. The art transaction unit (1200) can, based on the first key received from the seller terminal (5000) and the second key matching the encryption serial number received from the seller terminal (5000), decrypt the encryption serial number using the first key and the second key as decryption keys to derive the decryption serial number.

In the second owner verification step, the decryption serial derived in the second decryption step can be searched for in an external blockchain server (4000), and a serial corresponding to the decryption serial can be derived from among the serials pre-stored in the external blockchain server (4000), and the art transaction unit (1200) can receive owner information stored matching the corresponding serial from the external blockchain server (4000). The art transaction unit (1200) can determine whether the owner information received from the external blockchain server (4000) and the self-information received from the seller terminal (5000) match, and if the owner information and the self-information match, the owner can be authenticated that the user of the seller terminal (5000) is the owner of the corresponding registered art piece. Thereafter, the seller terminal (5000) that has been authenticated as the owner can register the sale of the corresponding registered art piece.

Since the sale of the registered artwork is registered in the server system (1000), the server system (1000) can update the owner information of the registered artwork. This will be described later.

Figure 5 schematically illustrates the initialization step, matching step, and ownership update step performed by the art transaction unit (1200) according to one embodiment of the present invention.

As illustrated in FIG. 5, the art transaction unit (1200) initializes the first key and derives an encryption key based on the second key when the owner information and the self-information match in the second owner verification step to verify the owner and receives a sale registration for the registered art piece from the seller terminal (5000); receives, from the buyer terminal (3000) of the buyer who received the registered art piece, buyer information about the buyer and a set first key set by the buyer for the first key; derives a modified second key for the second key based on the set first key and the encryption key, and matches an encryption serial number for the registered art piece with the modified second key; And based on the above-mentioned first key and the second key for change, a decryption serial is derived by decrypting the corresponding encryption serial, and an information update step of searching for the corresponding decryption serial from the external blockchain server (4000) and updating the owner information for the serial corresponding to the decryption serial with the purchaser information can be performed.

In the second owner verification step, if it is confirmed that the owner of the registered work of art is a user of the seller terminal (5000) and the server system (1000) receives a sales registration from the seller terminal (5000), the initialization step can be performed.

In the initialization step, the art transaction department (1200) can initialize the first key for the seller terminal (5000). For example, the first key can be made null. In addition, in the initialization step, an encryption key can be derived based on the second key.

The above encryption key may be stored in preparation for the return of registered artwork without being deleted from the server system (1000). Details on this will be described later.

The above encryption key may correspond to a decryption key capable of decrypting the encryption serial. According to one embodiment of the present invention, the encryption key may be derived based on the second key and the encryption serial. According to another embodiment of the present invention, the encryption key may be derived based on the first key and the second key before initialization.

According to one embodiment of the present invention, when a sale is registered from a seller terminal (5000) to a server system (1000), the first key for the seller terminal (5000) is initialized to a null state, so that the seller terminal (5000) can have the effect of not being able to authenticate ownership from the moment of sale registration.

In the case where the user (buyer) of the purchaser terminal (3000) receives the registered artwork, selects the registered artwork through the purchaser terminal (3000) using an application implemented in the server system (1000), and enters the first key setting for the first key, the artwork transaction department (1200) can perform a setting reception step of deriving an encryption serial number of the registered artwork from the purchaser terminal (3000) and receiving buyer information about the user of the purchaser terminal (3000) and the first key setting.

The above setting first key may correspond to a key set by the purchaser in the null state.

In the matching step, a change second key can be derived based on the setup first key received from the purchaser terminal (3000) and the encryption key derived in the initialization step. The change second key and the setup first key can correspond to a decryption key for decrypting the encryption serial.

Next, in the matching step, the second change key can be matched with the encryption serial number of the registered artwork. That is, the encryption serial number and the second change key can be matched and stored in the server system (1000).

In the ownership update step, the encrypted serial number received from the purchaser terminal (3000) can be decrypted based on the first key set from the purchaser terminal (3000) and the second key changed from the matching step to derive a decrypted serial number, and the decrypted serial number can be searched for in an external blockchain server (4000), and a serial number corresponding to the decrypted serial number can be derived from among the serial number stored in the external blockchain server (4000), and the art transaction department (1200) can update the owner information stored by matching the serial number with the purchaser information received from the purchaser terminal (3000).

Figure 6 schematically illustrates an art rental unit (1300) according to one embodiment of the present invention.

As illustrated in FIG. 6, the server system (1000) further includes an art rental unit (1300), and the art rental unit (1300) receives a rental request from a rental terminal (6000) for a rental user who wishes to rent a registered art piece registered in the server system (1000) at all times, and when receiving a rental approval from an owner terminal (2000) for the owner of the registered art piece, receives a first key from the owner terminal (2000) and authenticates the ownership of the registered art piece based on the first key, and changes the first key for the registered art piece according to the rental user so that the ownership can be transferred to the rental user during the rental period of the registered art piece, and the art rental unit (1300) includes: a rental reception step of receiving a rental request for the rental art piece and a set first key from the rental user terminal (6000); A third information receiving step of receiving a first key input from the owner terminal (2000) and self-information about the owner from the owner terminal (2000), and deriving an encryption serial number for the rental artwork; A third decryption step of deriving a second key matching the encryption serial number based on the encryption serial number derived in the third information receiving step, and deriving a decryption serial number by decrypting the encryption serial number based on the first key received in the third information receiving step and the second key; A third owner verification step of querying the decryption serial number from the external blockchain server (4000) and receiving owner information about the serial number corresponding to the decryption serial number to confirm whether the owner information matches the self-information received in the third information receiving step; And in the third owner verification step, if the owner information and the self-information match and the owner is verified, and a rental approval for the rental artwork is received from the owner terminal (2000), the first key is initialized, and a rental initialization step of storing the set first key received in the rental reception step as the first key can be performed.

The art rental unit (1300) can temporarily change the owner of a rental art piece rented from a renter terminal (6000) to the user of the renter terminal (6000) by performing a rental reception step, a third information reception step, a third decryption step, a third owner step, and a rental initialization step.

Specifically, the rental terminal (6000) can select the corresponding rental artwork and input the first setting key through an application. Accordingly, the artwork rental unit (1300) can receive a rental request for the rental artwork and the first setting key from the rental terminal (6000) at the rental reception stage.

The owner terminal (2000) can select the rental artwork through the application and input the first key, so that in the third information receiving step, the owner terminal (2000) can receive the first key and the user's self-information about the owner terminal (2000), and can derive an encryption serial number for the rental artwork.

The above self-information may correspond to information that can identify the owner, and may correspond to a form corresponding to owner information stored in an external blockchain server (4000).

In the third decryption step, the encryption serial number received from the owner terminal (2000) is searched to derive an encryption serial number matching the encryption serial number for multiple artworks stored in the server system (1000), and a second key matching the encryption serial number can be derived. The artwork rental unit (1300) can, based on the first key received from the owner terminal (2000) and the second key matching the encryption serial number received from the owner terminal (2000), decrypt the encryption serial number using the first key and the second key as decryption keys to derive the decryption serial number.

In the third owner verification step, the decryption serial derived in the third decryption step can be searched for in an external blockchain server (4000), and a serial corresponding to the decryption serial can be derived from among the serials pre-stored in the external blockchain server (4000), and the artwork rental unit (1300) can receive owner information stored matching the corresponding serial from the external blockchain server (4000). The artwork rental unit (1300) can determine whether the owner information received from the external blockchain server (4000) and the self-information received from the owner terminal (2000) match, and if the owner information and the self-information match, the owner can be authenticated to verify that the owner of the artwork is the user of the owner terminal (2000).

In the third owner verification step, if it is confirmed that the owner of the rental artwork is the user of the owner terminal (2000) and the server system (1000) receives rental approval from the owner terminal (2000), the rental initialization step can be performed.

In the rental initialization step, the art rental unit (1300) can initialize the first key for the owner terminal (2000). For example, the first key can be made null, and the first key set for the renter terminal (6000) received in the rental reception step can be stored as the first key.

In addition, in the rental initialization step, an encryption key can be derived based on a second key matching the corresponding encryption serial stored on the server system (1000). The encryption key can correspond to a decryption key capable of decrypting the encryption serial, and is as described above.

According to one embodiment of the present invention, since the first key set in the renter terminal (6000) during the rental period can be stored as the first key, the owner can be temporarily transferred to the renter terminal (6000) during the rental period, thereby achieving the effect.

In the case where the user of the rental terminal (6000) receives the rental artwork and selects the rental artwork through the rental terminal (6000) using an application implemented in the server system (1000), and enters the first key for the first key, the artwork rental unit (1300) may receive, from the rental terminal (6000), self-information about the user of the rental terminal (6000) and the first key, derive an encryption serial number of the registered artwork, derive a second key based on the first key received from the rental terminal (6000) and the encryption key derived in the rental initialization step, and perform a reset step of matching the second key with the encryption serial number and storing it.

The above-mentioned second change key and the above-mentioned first setting key may correspond to a decryption key for decrypting the encryption serial.

The art rental unit (1300) can perform a rental update step, and in the rental update step, the encrypted serial number received from the rental terminal (6000) can be decrypted based on the first key set from the rental terminal (6000) and the second key changed from the reset step to derive a decrypted serial number, and the decrypted serial number can be searched for in an external blockchain server (4000), and a serial number corresponding to the decrypted serial number can be derived from among the serial number stored in the external blockchain server (4000), and the ownership authentication unit (1100) can update the owner information stored matching the serial number with the self information received from the rental terminal (6000).

The art rental unit (1300) can further perform a rental return step, and the rental return step can receive a return request and a setup first key from the owner terminal (2000), initialize the setup first key, and receive a reset first key as the first key from the owner terminal (2000).

The artwork rental unit (1300) can further perform a rental recovery step, and the rental recovery step can initialize the set first key and receive a reset first key as the first key from the owner terminal (2000) if the owner terminal (2000) does not return the rental artwork after the rental period.

That is, in the rental return stage and rental recovery stage, by receiving the reset first key as the first key from the owner terminal (2000), the ownership of the rental artwork can be transferred to the owner terminal (2000) according to the reset first key. Details on this follow the above description.
