Description

Method for brokering data {METHOD FOR BROKERING DATA}

This disclosure relates to a method for brokering data, and specifically relates to a method for brokering data between a seller who wants to sell data and a buyer who wants to purchase data.

Among the terms mentioned in the recent European Union (EU) Commission meeting, there is a term called technological sovereignty. Technological sovereignty may be a new type of sovereignty, also called technological information or data sovereignty. Recognized from the aspect of the traditional concept of sovereignty as geographical territory, technological sovereignty can be understood as recognizing the economic value of the 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 held by individuals, there may be a need to be brokered with other people who purchase the data, or for individuals with such valuable data to be grouped.

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 an individual's data is valuable, its value can only be recognized when it is passed on to other individuals who can utilize the data. Additionally, even if an individual sells the data he or she owns 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's seller terminal. The server may obtain first data in response to the received sales request signal. After the first data is acquired, 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 portion of the sales cost obtained by selling the first data to the seller terminal. The server can deduct the commission to be earned by the server manager from the sales cost and then deliver the sales amount minus the commission to the seller terminal. Hereinafter, a method for mediating data performed by a server according to the present disclosure will be described through FIGS. 1 to 5.

1 illustrates an example system for performing a method for brokering 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 for implementing the server 100, so the server 100 may have more or less components than the components 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.

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

The control unit 110 can typically process the overall operation of the server 100. The control unit 110 processes signals, data, information, etc. input or output through the components of the server 100 or runs an application program stored in the storage unit 120 to provide or process appropriate information or functions to the user. can do.

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

In the present disclosure, when a purchase request signal for purchasing the first data is received from at least one buyer terminal 300, the control unit 110 determines a selling cost for selling the first data in response to the purchase request signal. You 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 wish to purchase the first data increases. Accordingly, the control unit 110 may determine the selling cost of the first data by increasing the cost of the first data as the number of times the first data is selected from each of the at least one buyer terminal 300 increases. Here, the operation of selecting the first data includes an operation of at least one buyer terminal 300 inquiring the first data to purchase the first data and an operation of the at least one buyer terminal 300 purchasing the first data. It may include at least one etc.

In this disclosure, cost of goods sold may be determined based on when the first data was generated. For example, it can 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 created before the first data. For example, the second data may be data related to the 2021 Korean professional baseball league. The first data may be data related to the 2022 Korean professional baseball league. The time when the communication unit 130 receives a purchase request signal for purchasing the first data from at least one buyer terminal 300 may be July 1, 2022. In this case, the control unit 110 may determine the selling cost of the first data to be more expensive 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 represent the number of queries related to the first data. A query can be understood as a search request signal for searching a search term related to first data. In other words, the control unit 110 may determine a sales cost for selling the first data based on the search volume of the search term related to the first data within a plurality of time intervals. For example, it can be assumed that the first data is data related to baseball. The time when the communication unit 130 receives a purchase request signal for purchasing the first data from at least one buyer terminal 300 may be July 1, 2022. The data that at least one buyer wanted could be data related to Korea's professional baseball league in 2022. In 2021, due to certain circumstances, keywords related to baseball may have been searched more than in other years. If many baseball-related keywords are searched, the cost of purchasing baseball-related data may increase. However, from the perspective of at least one buyer who wants to purchase first data related to baseball on July 1, 2022, the cost of the data he or she wants to purchase is high as many search terms are searched for a specific reason in 2021. If measured, it may feel unreasonable. This may be because at least one piece of data that the buyer wants is data related to Korea's professional baseball league in 2022. Accordingly, the control unit 110 may determine a parameter indicating 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 related to the first data within a time interval close to the time of receiving a purchase request signal for purchasing the first data from at least one buyer terminal 300. You can. The control unit 110 may determine a sales cost for selling the first data based on the determined number of queries. Accordingly, a larger sales cost may be determined for popular data that is currently popular and causes searches, inquiries, and downloads from many users, and a relatively lower sales cost may be determined for data that is somewhat less popular. Therefore, buyers who want to purchase data can purchase data efficiently. Additionally, because data that has become somewhat unpopular is relatively cheap, sellers who want to sell data can also continue to sell their data. Hereinafter, an example of a method by which the control unit 110 determines the selling cost will be described with reference to FIG. 2.

Storage unit 120 may include memory and/or persistent storage media. Memory is a flash memory type, hard disk type, multimedia card micro type, card type memory (e.g. SD or XD memory, etc.), and 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 It may include at least one type of storage medium.

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

For example, the first data may exist in the seller's seller terminal 200. 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.

In another example, the first data may reside in an external data platform associated with 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. If 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 located 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.

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

In the present disclosure, the seller terminal 200 may be a seller's terminal that wishes to sell data.

At least one purchaser terminal 300 may include typical computer hardware (e.g., a device that may include computer processors, memory, storage, input and output devices, and other components of conventional computing devices; electronic communication devices such as routers, switches, etc. devices (electronic information storage systems such as network-attached storage (NAS) and storage area networks (SAN)) 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 buyer terminal 300 may include a personal computer (PC), a notebook (note book), a mobile terminal, a smart phone, a tablet PC, etc. owned by the buyer. It can include all types of terminals that can access wired/wireless networks.

In the present disclosure, the at least one buyer terminal 300 may be a terminal for each of at least one buyer who wishes 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 the blockchain protocol. The blockchain mainnet 400 can issue tokens according to a predetermined protocol and record and verify transactions regarding token ownership. In Figure 1, a single blockchain mainnet 400 is shown for convenience, but the embodiment is not limited thereto. The server 100 can communicate with multiple different types of blockchain mainnets 400. Each blockchain mainnet 400 can be operated by a blockchain protocol that supports NFT. Blockchain protocols that support NFT include Ethereum, WAX, FLOW, and Binance Smart Chain, but embodiments are not limited thereto. NFTs can be issued according to protocols such as Ethereum, WAX, and FLOW Binance Smart Chain mentioned above. The amount of NFT issued may be limited. For example, the issuance quantity of NFT may be 1. However, the embodiment is not limited thereto. The issuance quantity of NFT may be a number greater than 1. The issuance volume of NFTs may be significantly smaller than that 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 can cause nodes to record sales costs or transactions in blocks through a consensus algorithm. If sales costs are recorded on a blockchain network, it is virtually impossible for sales costs to be forged or altered. Accordingly, malicious users can be prevented from hacking and modifying records of sales expenses through their terminals.

The network 500 may be a closed network such as a Local Area Network (LAN) or a Wide Area Network (WAN), or an open network such as the Internet. The Internet uses the TCP/IP protocol and several services that exist at its upper layer, such as HTTP (Hyper Text Transfer Protocol), Telnet, FTP (File Transfer Protocol), DNS (Domain Name System), SMTP (Simple Mail Transfer Protocol), and SNMP. It refers to a worldwide open computer network structure that provides (Simple Network Management Protocol), NFS (Network File Service), and NIS (Network Information Service).

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

FIG. 2 is a flowchart illustrating an example of a method by which a server mediates data according to some embodiments of the present disclosure. FIG. 3 is a graph illustrating an example of a method by 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 the first data from at least one purchaser terminal 300 (S110).

Specifically, the communication unit 130 may receive a search request for searching a search word related to the first data from at least one purchaser terminal 300. In response to a search request, the control unit 110 may transmit information related to at least one data corresponding to the search term to at least one purchaser terminal 300. At least one data may include first data. Information related to at least one data may include, for example, the name of each of the at least one data, a summary of each of the at least one data, the size of each of the at least one data, or the 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 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.

In another example, the first data may reside in an external data platform associated with 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 control unit 110 may determine a sales 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 can be understood as a search request signal for searching a search term related to first data. In other words, the control unit 110 may determine a sales cost for selling the first data based on the search volume of the search term related to the first data. The control unit 110 may determine the selling cost for selling the first data by setting a higher cost as the search volume of the search term related to the first data increases within a plurality of time sections.

Specifically, selling cost can be determined based on the equation below.

here, is the size of selling costs, may be any natural number. is a natural number and may be an index representing each time section. Is It may be a weight given corresponding to the th time section. is the search volume of the search term related to the first data, May be a constant representing the length of one time interval. for example, may be an index representing a time interval such as one hour, one month, or one year. and Is It may be the search volume of the th time section.

Although not disclosed in this embodiment, , It will be obvious to those skilled in the art that the sales cost of second data, third data, etc. can also be calculated according to the search volume of related search words associated with each.

For convenience of explanation of the above equation, reference may be made to FIG. 3.

Figure 3(a) and Figure 3(b) are graphs to explain an example of a method by which a server determines a sales cost according to some embodiments of the present disclosure.

*The x-axis of the graph shown in (a) of Figure 3 may represent an index representing each time section. The x-axis can also represent the passage of time. The y-axis may represent the search volume of a search term related to the first data. a1 may represent the first search volume of the search term related to the first data in the first time period. The control unit 110 has an index indicating a time section. By assigning 1 to , the first search amount of the search term related to the first data in the first time period can be determined. a2 may represent the second search volume of the search term related to the first data in the second time period. The control unit 110 has an index indicating a time section. By assigning 2 to , the second search amount of the search word related to the first data in the second time period can be determined. And, a3 may represent the third search volume of the search word related to the first data in the third time period. The control unit 110 has an index indicating a time section. By assigning 3 to , the third search amount of the search term related to the first data in the third time period can be determined. The control unit 110 weights the search volume within each time section. can be given. The control unit 110 sets the weight based on the time when a purchase request signal for purchasing the first data is received from at least one buyer terminal 300. size can be determined. For example, the control unit 110 assigns a high weight to a time section close to the point at which the purchase request signal is received. size can be determined. This may also mean that the control unit 110 assigns a high weight to the search volume in a time section close to the time when the purchase request signal is received. For example, the second time section may be a time section when time has elapsed compared to the first time section. The third time section may be a time section when time has elapsed compared to the second time section. For a specific example, the first time period may be from January 1, 2020 to December 31, 2020. The second time segment may be from January 1, 2021 to December 31, 2021. The third time segment may be from January 1, 2022 to December 31, 2022. Here, the range of time intervals may be the same, and a constant It can be decided as. The control unit 110 controls the weight given to the second search amount (a2) in the second time period. The size of is the weight given to the first search amount (a1) in the first time interval. It can be determined to be larger than the size of . The control unit 110 controls the weight given to the third search amount (a3) in the third time section. The size of is the weight given to the second search amount (a2) in the second time interval. It can be determined to be larger than the size of . According to one embodiment, the control unit 110 uses a monotone increasing weight function. with the entered value can be decided. Monotonically increasing may mean that the function does not decrease in the defined section. That is, the interval in the function according to the present disclosure is from 1 to It can be defined as: starts from 1 It can be determined in a non-decreasing form during the interval up to. This may be to determine a larger sales cost for popular data that is currently popular and causes searches, inquiries, and downloads by many users, and to determine a relatively low sales cost for data that is somewhat less popular.

Specifically, referring to (b) of FIG. 3, the 1-1 search amount (b1) of the 1-1 time section in FIG. 3 (b) is the 1-2 search amount of the 1-2 time section. It may be more than the amount (b2). This may be because the popularity of baseball, a search term related to the first data, was greater in 2020 than in 2021. Additionally, the 1-2 search amount (b2) in the 1-2 time section may be greater than the 1-3 search amount (b3) in the 1-3 time section. This may be because the popularity of baseball, a search term related to the first data, was greater in 2021 than in 2022. In short, the search volume for the search term baseball related to the first data may gradually decrease. However, the time when 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 buyer terminal 300 may be some day in 2022. . If the value of baseball-related data decreases because the search volume for baseball-related search terms decreases compared to the previous year, users who sell baseball-related data may judge the decision on sales costs to be unreasonable. If the value of baseball-related data decreases because the search volume for baseball-related search terms decreases compared to the previous year, users may not create baseball-related data. Therefore, the control unit 110 uses a monotonically increasing or strong monotonically increasing weight function. with the entered value can be decided. For example, when the control unit 110 determines the sales cost of the first data based on the 1-1 search volume (b1) in the 1-1 time interval, the weight can be determined as the first size. When the control unit 110 determines the sales cost of the first data based on the 1-2 search volume (b2) in the 1-2 time period, the weight may be determined as a second size that is relatively larger than the first size. When the control unit 110 determines the sales cost of the first data based on the 1-3 search volume (b3) in the 1-3 time period, the weight may be determined as a third size that is relatively larger than the second size. Accordingly, a larger sales cost may be determined for popular data that is currently popular and causes searches, inquiries, and downloads from many users, and a relatively lower sales cost may be determined for data that is somewhat less popular.

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

In the present disclosure, cost information may include sales costs and a virtual wallet address for receiving sales costs. Here, the virtual wallet may be a virtual wallet that can store tokens or cryptocurrency. A virtual wallet address may be an address that allows other users to transfer cryptocurrency to a virtual wallet. The cost of sale may represent the amount of at least one token required for at least one buyer to purchase the first data.

When the sales cost is deposited from at least one buyer terminal 300, the communication unit 130 may transmit the first data to at least one buyer terminal 300 (S140).

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

According to some embodiments of the present disclosure, the control unit 110 encrypts 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. You can obtain deposit results. IPFS can be a network for sharing and storing data in a distributed file system. The deposit result may be the 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 sales 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 control unit 110 may upload the first data to IPFS through the communication unit 130. Accordingly, at least one purchaser terminal 300 can 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 the sales cost is obtained 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 can be understood as transferring a portion of at least one token to a virtual wallet address without a private key. Because the virtual wallet address does not have a private key, some portion of at least one token sent to the virtual wallet address cannot be used by others. Therefore, the operation of transmitting at least one token to a virtual wallet address for which a private key does not exist can be understood to mean burning at least one token. Depending on the embodiment, tokens collected in the virtual wallet address may actually be erased.

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

For example, the control unit 110 may determine 90% of the sales cost deposited from at least one buyer terminal 300 as a reward. The above-mentioned example is an example to help understand the explanation, and is not limited thereto. The control unit 110 may match the determined reward with the seller terminal 200 and record it. If the seller of the seller terminal 200 has recorded a certain amount of rewards or more, the seller can convert the reward into at least one token and withdraw it. Hereinafter, an example in which a seller of the seller terminal 200 converts a reward into at least one token and receives payment will be described with reference to FIG. 3.

According to the above-described configuration, the server 100 can obtain the 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 buyer terminal 300. As the purchase request signal is received, the server 100 may determine the selling cost of the first data. If the seller determines the selling cost for selling the first data, a fair value may not be set. This may be because the seller is the person who created the first data or is trying to make 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 set at a reasonable price, and further, the purchase and sale of data can be actively carried out.

Meanwhile, according to some embodiments of the present disclosure, the seller of the seller terminal 200 may convert the reward recorded by matching with the seller terminal 200 into at least one token and receive payment. 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.

FIG. 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 seller terminal 200 to the first virtual wallet associated with the seller terminal 200 (S210). The withdrawal request signal may include information about the amount of tokens for which the seller wishes to withdraw at least one token.

The control unit 110 may determine whether the reward can be converted into at least one token based on the withdrawal request signal and the reward recorded by matching with the seller terminal 200 (S220).

For example, in the storage unit 120, information about the ratio representing the size of the reward required per token may be pre-stored in a table or the like. For example, the size of reward required per token may be 10. If the size of the reward recorded and matched to the seller terminal 200 is 10, and a withdrawal request signal to withdraw one token is received from the seller terminal 200, the control unit 110 can convert the reward into a token. there is. The above-mentioned example is an example to help understand the explanation, and is not limited thereto.

If it is determined that conversion is possible (S230, Yes), the control unit 110 may convert the reward into at least one first token. And the control unit 110 may pay at least one converted token to the seller terminal 200 through the communication unit 130 (S240). For example, the control unit 110 may pay at least one token to the first virtual wallet associated with the seller terminal 200. The seller may withdraw at least one token issued to the first virtual wallet.

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

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

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

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

The control unit 110 may incinerate at least a portion of at least one converted token (S242). Here, burning part of at least one token can be understood to mean sending 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 seller terminal 200 may be 20. The control unit 110 can transmit one token out of 20 tokens to a virtual wallet address without a private key through the communication unit 130. Because the virtual wallet address does not have a private key, tokens sent to the virtual wallet address cannot be used by other people. Therefore, the operation of transferring a token to a virtual wallet address for which a private key does not exist can be understood to mean incinerating the token. Depending on the embodiment, tokens collected in the virtual wallet address may actually be erased.

The control unit 110 may pay at least one partially incinerated token to the seller terminal 200 through the communication unit 130 (S243).

Specifically, the control unit 110 may pay at least one partially burned token to the first virtual wallet associated with the seller.

The incineration of tokens may be used by the administrator of the server 100, a company issuing tokens related to the server 100, or a cryptocurrency exchange to limit the supply of tokens distributed in the market. If token issuance is not limited and is supplied indefinitely, the value of tokens held by sellers or buyers may fall. Accordingly, when the server 100 converts a reward into at least one token, it can incinerate at least a portion of the converted at least one token. In addition, the server 100 may pay at least one token of which at least a portion has been burned to the seller terminal 200. 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, and the general principles defined herein may be applied to other embodiments without departing from the scope of the disclosure. Thus, the present disclosure is not limited to the embodiments presented herein but is to be interpreted in the broadest scope consistent with the principles and novel features presented herein.
