Description

A method for brokering data {METHOD FOR BROKERING DATA}

The present disclosure relates to a method for mediating data, and specifically relates to a method for mediating data between a seller who wants to sell data and a buyer who wants to purchase data.

Among the terms mentioned at the recent European Union (EU) Executive Committee meeting, the term “Technological Sovereignty” exists. Technology sovereignty may be a new kind of sovereignty, also called technological information or data sovereignty. Technology sovereignty recognized from the aspect of the traditional sovereign concept of geographic territory can be understood as recognizing the economic value of data held by users.

The value and usefulness of personal data can be further increased when combined with other people's data or public data. Therefore, in order to utilize the potential benefits of data possessed by individuals, it may be necessary to mediate with other people who will purchase the data, or to group individuals with such valuable data.

However, it may not be easy for individuals to find buyers for the data they hold. The value of data cannot be absolute, and even if the data an individual possesses is valuable data, its value can only be recognized when it is delivered to other individuals who can utilize the data. In addition, even if an individual sells his or her own data to another individual, receiving monetary goods from the other individual may not be guaranteed.

In the present disclosure, the server may receive a sales request signal for selling the first data held by the seller from the seller terminal of the seller. The server may obtain first data in response to the received sales request signal. After obtaining the first data, the server may receive a purchase request signal for purchasing the first data from at least one purchaser terminal. In response to the purchase request signal, the server may sell the first data. When the first data is sold, the server may transfer at least a part of the sales cost obtained by selling the first data to the seller terminal. The server may transfer the sales amount excluding the commission to the seller terminal after excluding the commission to be obtained by the manager of the server from among the selling costs. Hereinafter, a method for mediating data performed by a server according to the present disclosure will be described with reference to FIGS. 1 to 5.

1 illustrates an exemplary system for performing a method for mediating data in accordance with some embodiments of the present disclosure.

Referring to FIG. 1 , the server 100 may include a control unit 110, a storage unit 120, and a communication unit 130. However, the above-described components are not essential to implement the server 100, so the server 100 may have more or fewer components than those listed above.

Server 100 may include any type of computer system or computer device, such as, for example, a microprocessor, mainframe computer, digital processor, portable device or device controller, and the like.

Server 100 may include typical computer hardware (e.g., computer processors, memory, storage, input and output devices, and other devices that may include components of conventional computing devices; electronic communications devices such as routers, switches, etc.; network attachments). A combination of storage (electronic information storage systems, such as network-attached storage (NAS) and storage area networks (SAN)) and computer software (ie, instructions that cause a computing device to function in a particular way). may be used to achieve desired system performance.

The control unit 110 may typically handle overall operations of the server 100 . The control unit 110 provides or processes appropriate information or functions to the user by processing signals, data, information, etc. input or output through the components of the server 100 or by running an application program stored in the storage unit 120. can do.

The control unit 110 may be composed of one or more cores, such as a central processing unit (CPU), a general purpose graphics processing unit (GPGPU), a tensor processing unit (TPU), and the like. It may include a processor for data analysis of.

In the present disclosure, when a purchase request signal for purchasing first data is received from at least one purchaser terminal 300, the controller 110 determines a selling cost for selling the first data in response to the purchase request signal. can The cost of the first data may increase as the value of the first data increases. The value of the first data may be evaluated higher as there are more other users who need the first data. In other words, the cost of the first data may increase as the number of buyers who want to purchase the first data increases. Accordingly, the controller 110 may determine the selling cost of the first data in such a way that the cost of the first data increases as the number of times the first data is selected from each of the at least one purchaser terminal 300 increases. Here, the operation of selecting the first data includes an operation in which at least one purchaser terminal 300 searches for the first data in order to purchase the first data and an operation in which the at least one purchaser terminal 300 purchases the first data. etc. may include at least one.

In the present disclosure, the selling cost may be determined based on a time point when the first data is generated. For example, it may be assumed that the first data is data related to baseball. The server 100 may hold second data similar to the first data. The second data may also be data related to baseball. The second data may be data generated before the first data. For example, the second data may be data related to the Korean professional baseball league in 2021. The first data may be data related to the Korean professional baseball league in 2022. The point in time when the communication unit 130 receives a purchase request signal for purchasing the first data from at least one purchaser terminal 300 may be July 01, 2022. In this case, the controller 110 may determine the selling cost of the first data to be higher than that of the second data.

According to some embodiments of the present disclosure, the selling cost may be determined according to a parameter associated with the first data within a plurality of time intervals. Here, the parameter may indicate the number of queries related to the first data. A query may be understood as a search request signal for searching for a search word related to the first data. In other words, the controller 110 may determine a sales cost for selling the first data based on a search volume of a search word related to the first data within a plurality of time intervals. For example, it may be assumed that the first data is data related to baseball. The point in time when the communication unit 130 receives a purchase request signal for purchasing the first data from at least one purchaser terminal 300 may be July 01, 2022. The data that at least one buyer wanted could be data related to Korea's professional baseball league in 2022. In 2021, keywords related to baseball may have been searched more compared to other years due to specific circumstances. When many baseball-related keywords are searched for, the cost of purchasing baseball-related data may increase. However, from the point of view of at least one buyer who wants to purchase the first data related to baseball on July 01, 2022, the cost of the data he/she wants to purchase is high as the number of search terms is searched for a specific reason in 2021 If measured, it can feel absurd. It may be because the data that at least one buyer wants is data related to Korea's professional baseball league in 2022. Accordingly, the controller 110 may determine a parameter representing the number of queries related to the first data within a plurality of time intervals. For example, the control unit 110 determines the number of queries associated with the first data within a time interval close to the time when a purchase request signal for purchasing the first data is received from at least one purchaser terminal 300 . can The controller 110 may determine a selling cost for selling the first data based on the determined number of queries. Accordingly, a larger selling cost may be determined for popular data that is currently popular and causes search, inquiry, and download from many users, and a relatively low selling cost may be determined for data that has become somewhat popular. Therefore, buyers who want to purchase data can purchase data efficiently. In addition, since data that is somewhat out of popularity is relatively cheap, sellers who want to sell data can also sell their data steadily. Hereinafter, an example of a method for determining the sales cost by the controller 110 will be described with reference to FIG. 2 .

The storage unit 120 may include a memory and/or a permanent storage medium. Memory is a flash memory type, a hard disk type, a multimedia card micro type, a card type memory (eg SD or XD memory, etc.), RAM (Random Access Memory, RAM), SRAM (Static Random Access Memory), ROM (Read-Only Memory, ROM), EEPROM (Electrically Erasable Programmable Read-Only Memory), PROM (Programmable Read-Only Memory), magnetic memory, magnetic disk, optical disk At least one type of storage medium may be included.

In the present disclosure, the storage unit 120 may store first data of the seller.

As an example, the first data may exist in the seller terminal 200 of the seller. The communication unit 130 may receive a sales request signal for selling the first data from the seller terminal 200 . In response to the sales request signal, the communication unit 130 may receive first data from the seller terminal 200 . The control unit 110 may store the received first data in the storage unit 120 .

As another example, the first data may exist in an external data platform related to the seller. The communication unit 130 may receive a sales request signal for selling the first data from the seller terminal 200 . In response to the sales request signal, the communication unit 130 may transmit a request signal for transferring or copying the first data from the external data platform to the external data platform. When transmission of the first data from the external data platform to the server 100 is permitted in response to the request signal, the communication unit 130 may receive the first data from the external data platform. The control unit 110 may store the received first data in the storage unit 120 .

The communication unit 130 is between the server 100 and the communication system, between the server 100 and the seller terminal 200, between the server 100 and at least one buyer terminal 300, and between the server 100 and the blockchain mainnet. It may include one or more modules that enable communication between 400 or between server 100 and network 500 .

Merchant terminal 200 may include typical computer hardware (e.g., computer processor, memory, storage, input and output devices, and other components of existing computing devices; electronic communication devices such as routers, switches, etc.; networks; A combination of electronic information storage systems such as network-attached storage (NAS) and storage area network (SAN) and computer software (ie, instructions that cause a computing device to function in a particular way). may be used to achieve desired system performance. The seller terminal 200 may include a PC (personal computer), a notebook (note book), a mobile terminal, a smart phone (smart phone), a tablet PC (tablet pc), etc. owned by the seller, It may include all types of terminals capable of accessing wired/wireless networks.

In the present disclosure, the seller terminal 200 may be a terminal of a seller who wants to sell data.

At least one purchaser terminal 300 may include typical computer hardware (eg, computer processor, memory, storage, input and output devices, and other components of conventional computing devices; electronic communications such as routers, switches, etc.) Devices; electronic information storage systems such as network-attached storage (NAS) and storage area networks (SANs) and computer software (i.e., instructions that cause a computing device to function in a particular way). ) may be used to achieve the desired system performance. At least one purchaser terminal 300 may include a personal computer (PC), a notebook (note book), a mobile terminal (mobile terminal), a smart phone (smart phone), a tablet pc (tablet pc), etc. owned by the purchaser. and may include all types of terminals capable of accessing wired/wireless networks.

In the present disclosure, at least one purchaser terminal 300 may be a terminal of each of at least one purchaser who wants to purchase data.

The blockchain mainnet 400 may be a network that launches and operates a blockchain project. The blockchain mainnet 400 is composed of an unspecified number of nodes, and can record transactions and verify them by a blockchain protocol. The blockchain mainnet 400 can issue tokens according to a predetermined protocol and record and verify transactions for ownership of tokens. In FIG. 1, one block chain mainnet 400 is shown for convenience, but the embodiment is not limited thereto. The server 100 may communicate with a plurality of blockchain mainnets 400 of different types. Each blockchain mainnet 400 can be operated by a blockchain protocol that supports NFTs. Blockchain protocols that support NFT include Ethereum, WAX, FLOW, Binance Smart Chain, etc., but the embodiment is not limited thereto. NFTs can be issued according to protocols such as Ethereum, WAX, and FLOW Binance Smart Chain. The issuance amount of NFT may be limited. For example, the issue amount of NFT may be 1. However, the embodiment is not limited thereto. The issuance amount of NFT may be a number greater than 1. The issuance volume of NFTs may be significantly smaller than the issuance volume of fungible tokens.

In the present disclosure, when the sales cost is determined, the control unit 110 transmits the sales cost or a transaction including the sales cost to at least one node included in the blockchain mainnet 400 through the communication unit 130, thereby providing a plurality of can cause the nodes of to write a sale cost or transaction into a block via a consensus algorithm. When the sales cost is recorded on the blockchain network, it is virtually impossible for the sales cost to be counterfeited or tampered with. Accordingly, malicious users can be prevented from hacking and modifying sales cost records through their own terminals.

The network 500 may be a closed network such as a local area network (LAN) and a wide area network (WAN) or an open network such as the Internet. Internet consists of the TCP/IP protocol and several services that exist on its upper layer, namely HTTP (Hyper Text Transfer Protocol), Telnet, FTP (File Transfer Protocol), DNS (Domain Name System), SMTP (Simple Mail Transfer Protocol), SNMP (Simple Network Management Protocol), Network File Service (NFS), and Network Information Service (NIS).

Hereinafter, a specific method for the server 100 to mediate data will be described.

2 is a flowchart illustrating an example of a method in which a server mediates data according to some embodiments of the present disclosure. 3 is a graph for explaining an example of a method in which a server determines a sales cost according to some embodiments of the present disclosure.

Referring to FIG. 2 , the communication unit 130 may receive a purchase request signal for purchasing first data from at least one purchaser terminal 300 (S110).

Specifically, the communication unit 130 may receive a search request for searching for a search word related to the first data from at least one purchaser terminal 300 . In response to a search request, the controller 110 may transmit information related to at least one piece of data corresponding to a search word to at least one purchaser terminal 300 . The at least one piece of data may include first data. The information related to the at least one data may include, for example, a name of each of the at least one data, a summary of each of the at least one data, a size of each of the at least one data, or an owner of each of the at least one data. The communication unit 130 may receive a purchase request signal for purchasing first data among at least one piece of data from at least one purchaser terminal 300 .

Meanwhile, the first data may be data obtained from the seller.

Specifically, the communication unit 130 may receive a sales request signal for selling the first data from the seller terminal 200 . In response to the sales request signal, the control unit 110 may obtain first data through the communication unit 130 .

As an example, the first data may exist in the seller terminal 200 . In response to the received sales request signal, the communication unit 130 may receive first data from the seller terminal 200 .

As another example, the first data may exist in an external data platform related to the seller. In response to the received sales request signal, the control unit 110 may transmit a request signal for transferring or copying the first data from the external data platform to the external data platform through the communication unit 130 . In response to the request signal, the communication unit 130 may receive first data from an external data platform.

In response to the purchase request signal, the controller 110 may determine a selling cost for selling the first data according to parameters related to the first data within a plurality of time intervals (S120). Here, the parameter may indicate the number of queries related to the first data. A query may be understood as a search request signal for searching for a search word related to the first data. In other words, the controller 110 may determine a sales cost for selling the first data based on a search volume of a search word related to the first data. The controller 110 may determine a selling cost for selling the first data in a manner of setting a higher cost as the search volume of the search word related to the first data increases within a plurality of time intervals.

Specifically, the sales cost may be determined based on the following equation.

It may be greater than the amount (b2). This may be because the popularity of baseball, which is a search term related to the first data, was greater in 2020 than in 2021. Also, the 1-2 retrieval amount b2 of the 1-2 th time interval may be greater than the 1-3 retrieval amount b3 of the 1-3 hr time interval. This may be because the popularity of baseball, which is a search term related to the first data, was greater in 2021 than in 2022. In short, the search volume of the search word related to the first data may gradually decrease. However, the time at which the communication unit 130 receives a purchase request signal for purchasing the first data or a search request signal for searching the first data from at least one purchaser terminal 300 may be any day in 2022. . When the value of baseball-related data decreases because the search volume of baseball-related search terms has decreased compared to the previous year, users selling baseball-related data may determine that the sales cost is unreasonable. When the value of baseball-related data decreases because the search volume of baseball-related search terms has decreased compared to the previous year, users may not generate baseball-related data. Therefore, the control unit 110 determines the weight function of a monotonically increasing form or a strong monotonically increasing form.

can decide For example, when the controller 110 determines the selling cost of the first data based on the 1-1 search quantity b1 of the 1-1 time interval, the weight

can be determined as the first size. When the controller 110 determines the selling cost of the first data based on the 1-2 search quantity b2 of the 1-2 time interval, the weight

may be determined as a second size relatively larger than the first size. When the controller 110 determines the selling cost of the first data based on the 1-3 search quantities b3 of the 1-3 time interval, the weight

may be determined as a third size relatively larger than the second size. Accordingly, a larger selling cost may be determined for popular data that is currently popular and causes search, inquiry, and download from many users, and a relatively low selling cost may be determined for data that has become somewhat popular.

Referring back to FIG. 2 , the communication unit 130 may transmit cost information including the determined selling cost to at least one purchaser terminal 300 (S130).

In the present disclosure, the cost information may include a sales cost and a virtual wallet address for receiving the sales cost. Here, the virtual wallet may be a virtual wallet capable of storing tokens or cryptocurrencies. The virtual wallet address may be an address indicating that other users can transfer cryptocurrency to the virtual wallet. The selling cost may indicate an amount of at least one token required for at least one purchaser to purchase the first data.

The communication unit 130 may transmit the first data to the at least one purchaser terminal 300 when the sales cost is received from the at least one purchaser terminal 300 (S140).

Specifically, the controller 110 may determine whether at least one token corresponding to the selling cost has been deposited into a virtual wallet associated with the server 100 . When it is determined that at least one token has been deposited, the controller 110 may transmit the first data to the at least one purchaser terminal 300 through the communication unit 130 .

According to some embodiments of the present disclosure, the control unit 110 determines the sales cost encrypted with the private key of at least one purchaser terminal 300 and uploaded to the InterPlanetary File System (IPFS) associated with the server 100. Deposit results can be obtained. IPFS can be a network for sharing and storing data in a distributed file system. The deposit result may be a result of a query indicating that at least one purchaser terminal 300 has delivered at least one token to the virtual wallet address of the server 100 . The control unit 110 encrypts the first data using the identification information of at least one purchaser terminal 300 and a hash value generated as the at least one purchaser terminal 300 uploads the selling cost to IPFS. can do. The control unit 110 may transmit the encrypted first data to at least one purchaser terminal 300 through the communication unit 130 . Alternatively, the controller 110 may upload the first data to IPFS through the communication unit 130 . Accordingly, the at least one purchaser terminal 300 may obtain the first data by decrypting the first data using the private key of the at least one purchaser terminal 300 .

According to some embodiments of the present disclosure, when at least one token corresponding to a selling cost is acquired from at least one purchaser terminal 300, the control unit 110 may burn a portion of the at least one token. there is. Burning a portion of at least one token may be understood as transferring a portion of at least one token to a virtual wallet address without a private key. Since the virtual wallet address does not have a private key, a portion of the at least one token sent to the virtual wallet address cannot be used by others. Accordingly, an operation of transmitting at least one token to a virtual wallet address in which a private key does not exist can be understood as meaning that at least one token is incinerated. Depending on the embodiment, the tokens collected in the virtual wallet address may actually be erased.

The controller 110 may match and record the reward determined based on the sales cost with the seller terminal 200 (S150). Here, the reward may mean a reward obtained by the seller as the first data is sold.

For example, the controller 110 may determine 90% of the sales cost deposited from at least one purchaser terminal 300 as a reward. The above example is an example for helping understanding of the description, and is not limited thereto. The controller 110 may record the determined reward by matching it with the seller terminal 200 . The seller of the seller terminal 200 may convert the reward into at least one token and withdraw the reward when a certain amount or more is recorded. Hereinafter, an example in which the seller of the seller terminal 200 converts the reward into at least one token and receives the reward will be described with reference to FIG. 3 .

According to the configuration described above, the server 100 may acquire first data that the seller wants to sell from the seller terminal 200 . The server 100 may receive a purchase request signal for purchasing the first data from at least one purchaser terminal 300 . As the purchase request signal is received, the server 100 may determine a selling cost of the first data. When the seller determines the selling cost for selling the first data, a fair value may not be assigned. This may be because the seller is a person who created the first data or a person who wants to gain a profit by selling the first data. Accordingly, the server 100 may determine a sales cost for selling the first data according to parameters related to the first data within a plurality of time intervals. Accordingly, the first data can be priced reasonably, and furthermore, the purchase and sale of the data can be actively performed.

Meanwhile, according to some embodiments of the present disclosure, the seller of the seller terminal 200 may be paid by converting a reward matched with the seller terminal 200 and recorded into at least one token. Hereinafter, an example in which the server 100 according to the present disclosure provides at least one token in response to a request from the seller terminal 200 will be described with reference to FIG. 4 .

4 is a flowchart illustrating an example in which a server provides at least one token in response to a request from a seller terminal, according to some embodiments of the present disclosure.

Referring to FIG. 4 , the communication unit 130 may receive a withdrawal request signal for withdrawing at least one token from the merchant terminal 200 to the first virtual wallet associated with the merchant terminal 200 (S210). The withdrawal request signal may include information about the amount of tokens that the seller wants to withdraw at least one token.

The controller 110 may determine whether or not the reward can be converted into at least one token based on the withdrawal request signal and the reward matched with the merchant terminal 200 and recorded (S220).

For example, the storage unit 120 may pre-store information on a ratio indicating the amount of reward required per token through a table or the like. For example, the amount of reward required per token may be 10. When the size of the reward matched with the merchant terminal 200 and recorded is 10, and a withdrawal request signal for withdrawing one token is received from the merchant terminal 200, the control unit 110 may convert the reward into a token. there is. The above example is an example for helping understanding of the description, and is not limited thereto.

When it is determined that conversion is possible (S230, Yes), the controller 110 may convert the reward into at least one first token. In addition, the control unit 110 may provide the converted at least one token to the seller terminal 200 through the communication unit 130 (S240). For example, the controller 110 may provide at least one token to a first virtual wallet related to the seller terminal 200 . The seller may withdraw at least one token paid to the first virtual wallet.

When it is determined that conversion is impossible (S230, No), the controller 110 may not convert the reward into at least one token. In this case, the control unit 110 may generate information indicating that the reward cannot be converted into at least one token, and transmit the information to the seller terminal 200 through the communication unit 130 .

Meanwhile, according to some embodiments of the present disclosure, the server 100 may incinerate a portion of the at least one token before providing the at least one token to the seller terminal 200 . Hereinafter, an example of a method of incinerating at least one token by the server 100 according to some embodiments of the present disclosure will be described with reference to FIG. 5 .

5 is a flowchart illustrating an example of a method of burning at least one token by a server according to some embodiments of the present disclosure.

Referring to FIG. 5 , the controller 110 may convert the reward into at least one token (S241).

The control unit 110 may burn at least a portion of the converted at least one token (S242). Here, the meaning of burning a part of at least one token may be understood as transferring a part of at least one token to a virtual wallet address without a private key.

For example, the number of tokens converted in response to the withdrawal request signal from the merchant terminal 200 may be 20. The control unit 110 may transmit one token out of 20 tokens to a virtual wallet address without a private key through the communication unit 130 . Since the virtual wallet address does not have a private key, tokens sent to the virtual wallet address cannot be used by others. Therefore, an operation of transmitting a token to a virtual wallet address where a private key does not exist can be understood as meaning that the token is incinerated. Depending on the embodiment, the tokens collected in the virtual wallet address may actually be erased.

The control unit 110 may provide at least one token of which at least a part is burned to the seller terminal 200 through the communication unit 130 (S243).

Specifically, the controller 110 may provide at least one token, at least partially burned, to a first virtual wallet associated with a seller.

The incineration of tokens may be used for the purpose of limiting the supply of tokens circulated in the market by the manager of the server 100, a token issuing company related to the server 100, or a cryptocurrency exchange. If the supply of tokens is not limited and the supply is unlimited, the value of the tokens held by the seller or buyer may decrease. Accordingly, when the server 100 converts the reward into at least one token, at least a portion of the converted at least one token may be burned. And, the server 100 may pay the seller terminal 200 at least one token, at least a part of which is burned. Accordingly, the value of the token issued by the server 100 can be maintained.

The description of the presented embodiments is provided to enable any person skilled in the art to make or use the present disclosure. Various modifications to these embodiments will be apparent to those skilled in the art of this disclosure, and the general principles defined herein may be applied to other embodiments without departing from the scope of this disclosure. Thus, the present disclosure is not to be limited to the embodiments presented herein, but is to be interpreted in the widest scope consistent with the principles and novel features presented herein.
