Specifically, the service providing apparatus may be in a state in which a database in which information about a plurality of blockchain-based networks is stored is built in advance. In this case, the database may be in a state in which information on blockchain-based networks corresponding to a plurality of types is stored. For example, the database may be in a state in which information on cost, information on period, and information on speed are stored similarly or identically to each item included in the condition information.

In other words, the service providing apparatus may pre-build a database for storing information of the object to be compared in order to determine the first channel based on condition information for the object obtained from the user terminal. For example, the service providing apparatus may be in a pre-built or pre-built state in which a database in which information on a plurality of blockchain-based networks is stored as shown in Table 1 below.

In such a situation, the service providing device can compare information and condition information on a plurality of blockchain-based networks included in the database, and based on the comparison result, a network having the most similar value to each item included in the condition information. may be determined as a network corresponding to the first channel. For example, the service providing apparatus may determine, as a network corresponding to the first channel, a network including the most items having the smallest difference from the plurality of items included in the condition information.

Thereafter, the service providing apparatus may encrypt the history information related to the transaction history performed based on the NFT issued for the object using the first encryption method set to be used in the determined first channel ( S422 ).

Specifically, the service providing device is the number of times registered with a blockchain-based network, which can mean a history of registration in a blockchain-based network based on the NFT issued to the object, and the number of times that transactions have been performed based on the NFT (to the object You can check information on the number of transfers and takeovers) as history information.

Here, the service providing apparatus may transmit the history information on the object encrypted by the first encryption method to the first server that manages the blockchain-based network corresponding to the first channel. Accordingly, the first server that manages the blockchain-based network corresponding to the first channel may receive history information about the object encrypted by the first encryption method from the service providing device.

Thereafter, the first server managing the blockchain-based network corresponding to the first channel transmits the history information about the object encrypted by the first encryption method received from the service providing device to the blockchain-based network corresponding to the first channel. can be registered in That is, the first server may register the history information on the object encrypted by the first encryption method on the block in the block chain-based network corresponding to the first channel.

Referring again to FIG. 4 , the service providing apparatus performing the service providing method for object authentication management using dual channel-based NFT according to an embodiment of the present invention is determined based on the first channel information and condition information. The object information on the object may be encrypted and registered in the network corresponding to the second channel supporting the first channel to be used in the second encryption method (S430).

6 is a flowchart illustrating a method in which second encryption is performed in a service providing method for object authentication management using dual channel-based NFT according to an embodiment of the present invention.

Referring to FIG. 6 , a service providing apparatus performing a service providing method for object authentication management using dual-channel-based NFT according to an embodiment of the present invention determines a criterion according to information on a first channel determined in a database. A plurality of satisfied networks may be determined as candidate channels that are candidates for determining the second channel ( S431 ).

Specifically, the service providing apparatus may check the criteria according to the information on the first channel determined based on the condition information and the information on the blockchain-based networks corresponding to the plurality of types stored in advance in the database.

In this case, the service providing apparatus may identify a plurality of networks compatible with the network corresponding to the first channel among the blockchain-based networks corresponding to the plurality of types stored in advance in the database. Thereafter, the service providing apparatus may determine the identified plurality of networks as candidate channels that are candidates for determining the second channel. The second channel is connected to a separate server independently of the blockchain network and may represent a database having a data communication function.

Thereafter, the service providing apparatus may determine a network satisfying a condition according to the condition information among a plurality of networks determined as a candidate channel to be a candidate as a second channel supporting the first channel ( S432 ).

Here, the specific process of determining, in the service providing apparatus, a network that satisfies the condition according to the condition information among a plurality of networks determined as the candidate channel as the second channel supporting the first channel, is similar to that previously described with reference to step S421. or the same. However, it may be different only for a portion determined by the service providing device from among a plurality of networks determined as a candidate channel rather than being determined from among a plurality of blockchain-based networks included in the database.

Thereafter, the service providing apparatus may obtain information on the first encryption method and encrypt the information and object information on the first encryption method using the second encryption method set to be used in the determined second channel ( S433 ).

Specifically, the service providing apparatus may acquire an identifier for detecting decryption based on the first encryption method as information on the first encryption method preset to be used in the first channel.

Additionally, the service providing device includes object information that may correspond to information other than the history information about the object (eg, information about the owner who owns the object, and the type of object (eg, in the case of art, artwork) If there is information on the type of copyright and copyright, information on the right holder who holds the copyright) can be obtained. The object information represents additional information regarding main transaction information of the object.

Thereafter, the service providing apparatus may encrypt the obtained information on the first encryption method and the obtained object information using a preset second encryption method to be used in a second channel determined as a channel supporting the first channel.

Thereafter, the service providing apparatus may store and register the encrypted first encryption method information and object information in the second server managing the network corresponding to the second channel ( S434 ). In this way, the service providing device stores only the minimum main transaction information in the first server based on the block chain, and stores the remaining additional information in the second server implemented in a separate encryption method to register and issue the NFT certificate. The effect of increasing both speed and speed can be expected.

Here, the specific process of storing and registering the information on the first encryption method and the object information encrypted in the service providing device in the second server that manages the network corresponding to the second channel is similar to that previously described with reference to step S423 or the same.
