Description

[Technical field]

[0001] The disclosure relates generally to a blockchain network-based watch face non-fungible token (NFT) creation and trading system, and more specifically, to an apparatus and method for creating watch face NFTs and utilizing authentication marks therefor to activate trading of the watch face NFTs. [Background technology]

[0002] A blockchain network is a technology that distributes a ledger that records transaction information across a P2P network, rather than on a central server at a specific institution, and allows participants in the network to jointly record and manage it. In other words, blockchain technology operates in a way that multiple participants jointly manage data, eliminating the need for a traditional central administrator, and has various advantages, such as low infrastructure costs for system construction and increased data integrity the more participants there are. Such blockchain networks are being introduced and used in various fields where contracts are made between multiple participants.

[0003] With the continuous development of intelligent wearable devices, smart watches have become popular, and the number of consumers wearing smart watches in their daily lives is increasing. Consumers wear smart watches for various purposes, such as fashion, business, health, and sports, and accordingly, smart watches of various styles are being released one after another.

[0004] A smartwatch watch face is a screen displayed on the display of the smartwatch and is displayed electronically, so that the design of the watch face can be freely changed, unlike a conventional analog watch. That is, a smartwatch supports a user to manually change the display form of the watch face, and the user can freely change the display content of the watch face corresponding to the display part of the smartwatch according to his / her mood, state, style, etc. As a result, watch faces with various personalities and functions are being designed, and specialized manufacturers that support watch face design editing services have appeared.

[0005] Conventionally, a creator creates a watch face and shares it online, and a consumer downloads the watch face online and applies it to their own wearable device to set the watch face. Here, since a watch face is embodied in a software program, it is relatively easy to replicate, and one watch face design is often used by multiple consumers. Therefore, the conventional watch face NFT production and trading system has a problem in that it cannot meet the needs of consumers who value individuality and want to own a unique watch face.

[0006] The above-mentioned technology is technical information possessed by the inventor for the purpose of deriving the present invention or acquired in the process of deriving the present invention, and does not necessarily represent publicly known technology disclosed to the general public prior to the filing of the application of the present invention.

[0038] The watch face NFT production and trading system 100 refers to a system that mediates the trading of watch face NFTs online. Specifically, the watch face NFT production and trading system 100 refers to a system in which trading of watch faces and watch face NFTs between users is performed through a watch face trading webpage. According to the watch face NFT production and trading system 100, a creator can create a watch face according to his / her taste and intention using a watch face production application, and a purchaser can purchase the watch face created by the creator. Here, the intermediary service provider can connect the creator and the purchaser so that a transaction between the creator and the purchaser can be performed. Specifically, the intermediary service provider can create a watch face NFT using the watch face created by the creator and store it in a blockchain network. Thereafter, the intermediary service provider can mediate the transaction of the watch face NFT by selling the watch face NFT at the request of the purchaser. According to one embodiment of the present disclosure, the watch face NFT production and trading system 100 may include a producer terminal 110, a buyer terminal 120, a wearable device 121, a watch face NFT market server 130, a blockchain network 140, and a network 150.

[0039] The creator terminal 110 refers to an electronic device operated by a creator who creates and sells watch faces. The creator can create a watch face using the creator terminal 110 and request an intermediary service provider who mediates the transaction of the watch face to mediate the transaction of the watch face. That is, the creator terminal 110 can be equipped with a watch face creation application for creating a watch face, and the creator can create a watch face by designing the watch face using the watch face creation application. According to an embodiment of the present disclosure, the creator terminal 110 may be a fixed terminal embodied as a computer device or a mobile terminal. Specifically, the creator terminal 110 may refer to a smart phone, a mobile phone, a navigation system, a computer, a notebook computer, a digital broadcasting terminal, a personal digital assistant (PDA), a portable multimedia player (PMP), or a tablet PC.

[0040] The buyer terminal 120 refers to an electronic device operated by a buyer who purchases a watch face or a watch face NFT. The buyer can connect to a watch face trading webpage using the buyer terminal 120 to purchase a watch face or a watch face NFT, which can be applied to the wearable device 121. According to an embodiment of the present disclosure, the buyer terminal 120 may also be a fixed terminal embodied in a computer device, or a mobile terminal.

[0041] The wearable device 121 refers to a wearable computing device that can be worn by a consumer. The wearable device 121 can refer to a computer in a wearable form such as a watch, glasses, etc. In the following, the wearable device 121 refers to, but is not limited to, a smart watch.

[0042] The watch face NFT market server 130 refers to a device operated by an intermediary service provider that operates an online shopping mall for trading watch faces and watch face NFTs. The watch face NFT market server 130 can perform general functions required in the process in which a creator and a buyer trade watch faces. Here, the trade can include both a single-price trade and a trade by auction. The watch face NFT market server 130 can support the trade of watch faces and watch face NFTs between a creator and a buyer through a watch face trading website. Here, the intermediary service provider can mint a watch face created by a seller and store it in a distributed manner in a blockchain network, and when there is a purchase request from a buyer, can mediate the trade of the watch face by conducting a trade through the seller's and buyer's virtual wallets. According to an embodiment of the present disclosure, the watch face NFT market server 130 can be embodied as a computer device or multiple computer devices that provide instructions, codes, files, contents, services, etc., and can store various data such as operation information for operating a shopping mall and sales information of watch face NFTs in a database.

[0043] The blockchain network 140 refers to a network node that uses blockchain technology. Specifically, the blockchain network 140 may refer to a network embodied by a technology that stores data that must be managed in a distributed data storage environment called a "block" formed by linking small data in a chain based on a P2P method, so that no one can arbitrarily modify the stored data and anyone can see the results of the changes. In the block, all data propagated to users before the block is found is recorded and can be transmitted equally to all users in a P2P method. Therefore, users cannot arbitrarily modify or omit data. A block has a link between the date it is found and the previous block, and such a collection of blocks can be called a blockchain, and blockchain technology can be a technology that bundles many records. When the watch face NFT market server 130 receives information about the user address, configuration, and price for the watch face NFT, it can store it in the blockchain network 140 via IPFS (interplanetary file system).

[0045] According to the watch face NFT production and trading system 100, a producer transmits a watch face that he / she has created to an intermediary service provider, and the intermediary service provider uses the transmitted watch face to mint and create a watch face NFT, which can be uploaded to a distributed file system and stored in a blockchain network. Here, the distributed file system is a P2P (peer to peer) distributed network that can host and back up data in multiple nodes, and can refer to IPFS. In addition, the intermediary service provider can upload sales information of the watch face NFT to a watch face trading webpage, and a purchaser can check the sales information of the watch face NFT and purchase it to trade the watch face.

[0046] Here, the intermediary service provider can prove that the watch face NFT has been embodied as an NFT by adding an authentication mark to the watch face in the process of creating the watch face NFT and then minting the watch face with the authentication mark. A specific configuration and operation of the watch face NFT creation and trading system 100 will be described in detail below.

[0047] FIG. 2 shows a schematic diagram 200 of a configuration of a watch face NFT creation and trading system 100 according to various embodiments of the present disclosure.

[0048] The creator terminal 110 performs a function of creating a watch face using a watch face creation application and transmitting the watch face to an intermediary service provider. The creator terminal 110 can generate a watch face by combining and editing watch face assets. Specifically, a creator can create a watch face through a watch face creation application displayed on the display of the creator terminal 110. The creator terminal 110 can transmit the created watch face together with the sales conditions desired by the creator to the watch face NFT market server 130.

The consumer terminal 120 can then transmit the purchased watch face NFT to the wearable device 121. As a result, the wearable device 121 can display the watch face NFT purchased by the consumer on the display 123.

[0050] The watch face NFT market server 130 functions to mediate transactions of watch face NFTs between creators and buyers using watch faces received from the creator terminal 110. The watch face NFT market server 130 can create watch face NFTs from watch faces and upload the watch face NFTs to a distributed file system. In addition, the watch face NFT market server 130 can upload sales information of watch face NFTs to a watch face trading website and support the provision and payment services of watch face NFTs in response to a purchase request from a buyer.

[0051] Furthermore, the watch face NFT market server 130 can mediate the trading of NFT image-based watch faces by uploading watch faces created from NFT images to a watch face trading website. That is, the watch face NFT market server 130 can control a watch face trading webpage where watch faces including NFT images and watch face NFTs can be traded.

[0052] The watch face NFT market server 130 may add an authentication mark to the watch face so that a purchaser who has purchased a watch face NFT can confirm that the watch face NFT he or she has purchased is an NFT. That is, the watch face NFT market server 130 may add an authentication mark to inform the purchaser that the watch face NFT is produced as an NFT, unlike a general watch face, and the wearable device 121 may display the watch face NFT to which the authentication mark is applied on the display.

According to an embodiment of the present disclosure, a resource of a watch face NFT may be stored in a distributed file system through the watch face NFT marketplace 410. In addition, an NFT market service application 411 for trading watch face NFTs may be called in the watch face NFT marketplace 410. Sales information of the watch face NFT may be uploaded to a watch face trading webpage through the NFT market service application, and a subscriber of the trading intermediary service may check the watch face NFTs for sale through the webpage.

[0066] A purchaser can access a watch face trading webpage via a mobile application 421, select a watch face NFT that the purchaser wishes to purchase, and request a purchase. When a purchaser requests a purchase of a watch face NFT, the watch face NFT market server 130 can control the resource of the watch face NFT to be transmitted from the distributed file system to the purchaser terminal 120. To this end, a digital wallet 423 can be linked to the watch face NFT marketplace 410, and a purchaser can use the purchased watch face by purchasing a watch face NFT and then transmitting it to the wearable device 121.

[0067] The watch face NFT market server 130 may add an authentication marker to a watch face while a buyer is in the process of applying a watch face NFT that has been minted and converted into an NFT in the watch face NFT marketplace 410 to a wearable device. Watch face NFTs are difficult to replicate and have unique characteristics because they are stored through a blockchain network, and the watch face NFT market server 130 may add an authentication marker to a watch face to increase buyers' desire to purchase watch face NFTs.

[0068] The authentication mark may refer to any mark that serves to verify that the watch face is an NFT. According to an embodiment of the present disclosure, the authentication mark may refer to a circular image of a preset color and shape, a graphic image such as a hexagon, and any other form of image for verifying the NFT, and may be added to the background of the watch face screen and displayed.

[0069] Specifically, the watch face NFT market server 130 may generate watch face NFT indicator information for an authentication indicator to be added to a watch face in the process of generating a watch face NFT. The watch face NFT market server 130 may select an authentication indicator corresponding to a color of a background image asset of the watch face, and the indicator information may indicate selection information for the authentication indicator. For example, the watch face NFT market server 130 may extract a main color from a background image asset of the watch face and select a hexagonal image of a complementary color of the main color as an authentication indicator. The watch face NFT market server 130 may add an authentication indicator to the watch face using the indicator information and mint the watch face to which the authentication indicator is added. As a result, a watch face NFT to which an authentication indicator that certifies that it has been converted into an NFT is added may be generated.

[0070] The watch face NFT market server 130 may upload sales information such as sales conditions and prices of the watch face NFT received from the creator terminal 110 to a watch face trading webpage. A purchaser may check the sales information of the watch face NFT on the watch face trading webpage and then transmit a purchase request for the watch face NFT he or she desires. When the watch face NFT market server 130 receives a purchase request for the watch face NFT, it may control the resource of the watch face NFT to be transmitted to the purchaser terminal 120 via the distributed file system. The purchaser terminal 120 may use the watch face NFT by transmitting the watch face NFT provided from the distributed file system to the wearable device 121.

[0071] The watch face NFT market server 130 may provide the creator or purchaser with the option of whether or not to add an authentication mark when the creator creates a watch face from an NFT image stored in the digital wallet 403 using the watch face creation application 401. When a watch face is created using an NFT image, the created watch face has unique characteristics even if it is not converted into an NFT, so the watch face NFT market server 130 may add an authentication mark for the NFT to a watch face created using an NFT image, but may provide the creator or purchaser with the option of whether or not to add the mark.

[0072] Specifically, the watch face NFT market server 130 identifies whether the received watch face is a watch face created using an NFT image. According to an embodiment of the present disclosure, the watch face NFT market server 130 can identify whether the watch face is created from an NFT image by checking whether the NFT image is used in the watch face creation application 401. When a watch face is created from an NFT image, the watch face NFT market server 130 can generate watch face NFT indicator information for an authentication indicator to be added to the watch face NFT. According to an embodiment of the present disclosure, the watch face NFT market server 130 can extract a main color from a background image asset of the watch face and select a circular shape of a complementary color of the main color as the authentication indicator. Thereafter, the watch face NFT market server 130 can transmit a confirmation request to the creator terminal 110 inquiring whether to apply the selected authentication indicator and receive a selection response requesting application of the authentication indicator. The watch face NFT market server 130 can confirm the selection response and add the authentication indicator to the watch face NFT.

[0073] Thereafter, the watch face NFT market server 130 can sell the watch face created from the NFT image using the same procedure as the selling procedure of the watch face NFT. The watch face NFT market server 130 can upload sales information for the watch face created from the NFT image or the watch face NFT minted from the watch face created from the NFT image to the watch face trading webpage, and receive a purchase request from the buyer terminal 120. When the watch face NFT market server 130 receives a purchase request for the watch face NFT, it can transmit the resource of the watch face NFT to the buyer terminal 120. The buyer terminal 120 can use the watch face created from the NFT image by transmitting the resource of the watch face NFT provided from the distributed file system to the wearable device 121.

[0074] The watch face NFT market server 130 may create a security indicator from an identifier of a creator who created the watch face in order to further enhance security for the watch face NFT. The watch face NFT market server 130 may extract a plurality of indicator units from the identifier of the creator and generate additional information on the order, position, and manner in which the plurality of indicator units are added. The watch face NFT market server 130 may then generate a security indicator from the plurality of indicator units using the additional information and add the security indicator to the watch face to generate a deformed watch face. The watch face NFT market server 130 may generate a watch face NFT by minting the deformed watch face.

[0075] Specifically, the watch face NFT market server 130 extracts a plurality of sign units from the creator's identifier. The creator's identifier may indicate a pin number of the creator consisting of a plurality of letters and numbers, and the watch face NFT market server 130 may extract a plurality of sign units by breaking down the creator's identifier into character units. According to an embodiment of the present disclosure, if the creator's identifier is 132465, the watch face NFT market server may extract 1, 3, 2, 4, 6, and 5 as a plurality of sign units.

[0076] The watch face NFT market server 130 then generates additional information for the position where the sign unit is added and the method of addition. Within the screen of the watch face, multiple pixels may be arranged along a shape pattern, and the additional information may indicate the position where each of the sign units is arranged along the shape pattern.

[0077] The watch face NFT market server 130 can determine a shape pattern according to the number of sign units and place multiple sign units at each of the vertex positions according to the shape pattern. For example, if the multiple sign units are 1, 3, 2, 4, 6, and 5, the watch face NFT market server 130 can determine a hexagonal shape pattern and associate 1, 3, 2, 4, 6, and 5 with each of the vertices of the hexagon. Thereby, the positions of the sign units 1, 3, 2, 4, 6, and 5 in the watch face screen can be determined.

[0078] The watch face NFT market server 130 generates a security sign using the additional information. After the sign unit is arranged, the watch face NFT market server 130 can change the RGB color value of the pixel at the position where the sign unit is arranged. According to an embodiment of the present disclosure, the watch face NFT market server 130 can generate a security sign by changing the RGB color value of the pixel at which the sign unit is arranged to a value obtained by subtracting a value corresponding to the sign unit from the RGB color value of the pixel at which the sign unit is arranged. If the color change is large, the buyer is likely to recognize the security sign, so the watch face NFT market server 130 can determine the color of the unit sign to be similar to the surrounding color so that the buyer cannot visually detect the sign. For example, after sign units 1, 3, 2, 4, 6, and 5 are arranged in a hexagonal shape pattern, the watch face NFT market server 130 can subtract 1 from the first RGB color value for the pixel position where 1 is arranged and subtract 3 from the second RGB color value for the pixel position where 3 is arranged. In this manner, the watch face NFT market server 130 can modify the pixel values ​​of all six pixels to generate a security signature.

[0079] The watch face NFT market server 130 can generate a modified watch face by adding a security tag to the watch face, and can generate a watch face NFT by minting the modified watch face. The watch face NFT thus generated has high security because a tag corresponding to the creator's identifier is added.

[0080] FIG. 5 shows an example of a watch face creation application 401 and an authentication indicator 500 in a watch face NFT creation and trading system 100 according to various embodiments of the present disclosure.
