The present disclosure relates to a service providing server that provides a tournament game service that supports participation in a game tournament through the setting of a non-fungible token (NFT)-based user profile and the operating method thereof.
Recently, as various electronic terminals including desktop PCs, smart phones, tablet PCs, console game machines, etc., have been released, the number of persons who play games through the electronic terminals has increased.
In particular, the recent electronic terminals provide an environment which enables playing games with other persons through online, in that the electronic terminals enable online connections.
As such, as the environment to play the games with other persons online has widely spread, an interest in the introduction of a new business model using online-based games is also increasing.
Normally, the online-based games are designed to allow persons to compete with each other in an online environment, so it is possible to consider introduction of a predetermined tournament service using the online-based games.
For example, by holding a tournament competition using a number of games so that persons participate in the tournament of the game they want, the introduction of a business model that pays a certain reward to the winner who wins a specific tournament competition can be considered.
However, in order to provide a tournament platform service using these games, user management technology needs to be introduced, which allows anybody not to participate in the tournament, but allows only the users who qualify for participating in a predetermined tournament to participate in the tournament to improve the quality of the service.
In this regard, the introduction of service technology can be considered, which allows only predetermined certified members to participate in the tournament, and at the same time, issues a predetermined ticket for participating in the tournament, and allows only the persons who purchase this ticket to participate in the tournament of a specific game.
In addition, as the use of an NFT has increased recently, it is possible to use the method of issuing and managing a profile of a user who participates in the tournament as the NFT. Here, the non-fungible token (NFT) which means a ‘non-fungible token’ means a virtual asset that is impossible to replace each token with another token because a unique value is given to each token, and the NFT has an advantage of ensuring excellent reliability, and easily proving uniqueness and ownership of contents. Specifically, profile information of each user, which includes tournament participation history information of a user who participates in a tournament, level information calculated based on a tournament participation record, reward reception history information according to tournament participation, and information on the quantity of holding tickets for the tournament participation is included in an NFT and managed through a blockchain to support the user to own his/her own profile according to game tournament participation in the form of a predetermined virtual asset.
In that when the profile management through the NFT is performed, the information on the quantity of holding tickets to participate in the tournament can be included in the NFT of each user and managed through the blockchain, more reliable verification of a quantification of a user who intends to participate in the tournament may also be enabled.
The present disclosure has been made in an effort to provide a service providing server that provides a tournament game service that supports participation in a game tournament through the setting of a non-fungible token (NFT)-based user profile and the operating method thereof to support users to enjoy a game while competing by a tournament scheme jointly with other users in an online environment.

The game information storage unit 111 stores information on the number of required tickets for participating in tournaments of a plurality of predetermined respective games.
For example, the game information storage unit 111 may store information shown in Table 1 below.
The price information storage unit 112 stores purchase price information of the ticket for participating in the tournament.
For example, the price information storage unit 112 may store purchase price information of ‘5000 won per ticket’ as the purchase price information of the ticket.
When the profile generation unit 113 receives a new user registration request command for using the tournament game service from a first electronic terminal 10 of a first user, the profile generation unit 113 generates a first profile table for recording tournament participation history information of the first user, level information calculated based on a tournament participation record, reward reception history information according to tournament participation, and information on the quantity of holding tickets for the tournament participation.
In this regard, the first profile table may be configured in a form shown in Table 2 below.
indicates data missing or illegible when filed
Here, the level information means a kind of grade or score calculated based on a predetermined level calculation criterion according to the tournament participation record of the user. For example, when the level calculation criterion is designated so that the level is increased by ‘10 when winning the game by participating in a tournament for a specific game and the level is decreased by ‘5’ when losing the game, and when ‘user 1’ participates in the game, and wins 10 games and loses 5 games, the level of ‘user 1’ may be calculated as ‘75’. In addition, the ticket means a kind of token required for the user to participate in a tournament of a specific game.
The NFT generation unit 114 requests the first electronic terminal 10 to transmit identification information for identifying the first user, and when receiving first user identification information from the first electronic terminal 10, the NFT generation unit 114 generates a first NFT which includes the first profile table, and at the same time, includes the first user identification information as owner information.
Here, the first user identification information which means unique information for identifying the first user may become information such as a user ID for using the tournament game service, a wallet address for keeping cryptocurrency pre-issued for the first user, or a cellular phone number of a user.
In this regard, when the service providing server 110 of the present disclosure receives the first user identification information ‘1SASzdfe342sdfsdadZ09dfaawer123sdaf’ which is the wallet address for keeping the cryptocurrency of the first user from the first electronic terminal 10, the NFT generation unit 114 may generate the first NFT including the first profile table, and the first user identification information ‘1SASzdfe342sdfsdadZ09dfaawer123sdaf’ as the owner information.
When the first NFT is generated, the registration processing unit 115 registers and processes the first NFT in a predetermined blockchain network 100 for registering the NFT, and completes issuing the first NFT to complete new user registration.
In this case, according to an exemplary embodiment of the present disclosure, the registration processing unit 115 may generate a transaction including the first NFT, and then propagate the transaction to the blockchain network 100 in order to register and process the first NFT in the blockchain network 100. Then, any one node of a plurality of nodes 101, 102, 103, 104, 105, and 106 constituting the blockchain network 100 may generate a block including the transaction and propagate the generated block to the plurality of nodes 101, 102, 103, 104, 105, and 106. As a result, when the block is received in the plurality of nodes 101, 102, 103, 104, 105, and 106, the plurality of nodes 101, 102, 103, 104, 105, and 106 connects the block to blockchain data by a chain based on a previous block connected to blockchain data stored in each node by the chain to share the first NFT.
As such, when issuance of the first NFT is completed by the registration processing unit 115, the completion message transmission unit 116 generates a registration completion message indicating that issuance of the first NFT is completed and at the same time, indicating that the new user registration is completed, and transmits the registration completion message to the first electronic terminal 10.
In this case, when the first electronic terminal 10 receives the registration completion message from the service providing server 110 of the present disclosure, the first electronic terminal 10 may output the registration completion message on a screen as a text. Through this, the first user may confirm that issuance of the first NFT is completed and at the same time, that new subscription of the first user in the tournament game service is completed.
As such, when issuance of the first NFT is completed, the first user may perform purchasing a ticket for participating in a tournament of a predetermined game using the first electronic terminal 10. In this regard, the first user may access the service providing server 110 of the present disclosure, and then transmit a command of requesting purchasing tickets of a purchase quantity desired thereby, by using the first electronic terminal 10. In this regard, upon receiving the purchase request command of requesting
purchasing tickets as large as a first purchase quantity from the first electronic terminal 10 to the service providing server 110 of the present disclosure, the payment processing unit 117 requests transmission of payment means information to the first electronic terminal 10, and upon receiving first payment means information from the first electronic terminal 10, the payment processing unit 116 calculates a price corresponding to the first purchase quantity based on the purchase price information stored in the price information storage unit 112, and then perform payment processing for the calculated price based on the first payment means information.
For example, when the purchase price information of the ticket is designated as ‘5000 won per ticket’, and the service providing server 110 receives the purchase request command of requesting purchasing ‘5’ tickets from the first electronic terminal 10, the payment processing unit 117 may request transmission of the payment means information to the first electronic terminal 10, and when the service providing server 110 receives predetermined credit card information from the first electronic terminal 10 in response thereto, the payment processing unit 117 may calculate a price corresponding to the purchase quantity of ‘5’ tickets as ‘25000 won’ based on the purchase price information, and then perform payment processing for ‘25000 won’ based on the credit card information.
When the payment processing is completed, the profile update unit 118 generates a first transaction indicting that the first user possesses tickets of the first purchase quantity, and registers and processes the first transaction in the blockchain network 100 to process the quantity of holding tickets in the first profile table included in the first NFT registered in the blockchain network 100 to be increased by the first purchase quantity, and recorded.
In this regard, as in the above-described example, when the payment processing unit 117 completes payment processing for a price for a ticket purchase quantity of ‘5’, the profile update unit 118 generates the first transaction indicating that the first user possesses ‘5’ tickets, and registers and processes the first transaction in the blockchain network 100 to process the quantity of holding tickets in the first profile table included in the first NFT registered in the blockchain network 100 to be increased by ‘5’ which is the first purchase quantity, and recorded.
As a result, the first profile table shown in Table 2 above may be updated to Table 3 below.
In this case, according to an exemplary embodiment of the present disclosure, the profile update unit 118 may propagate the first transaction to the blockchain network 100 in order to register and process the first transaction in the blockchain network 100. Then, any one node of the plurality of nodes 101, 102, 103, 104, 105, and 106 constituting the blockchain network 100 may generate a block including the first transaction and propagate the generated block to the plurality of nodes 101, 102, 103, 104, 105, and 106. As a result, when the block is received in the plurality of nodes 101, 102, 103, 104, 105, and 106, the plurality of nodes 101, 102, 103, 104, 105, and 106 may record a quantity called ‘5’ as the information on the ticket holding quantity of the first user in the first profile table of the first NFT included in the blockchain data stored in each node based on the first transaction on the received block.
In such a situation, an operator of the service providing server 110 according to the present disclosure may hold a tournament competition for each of the plurality of games in order to provide the tournament game service, and in this case, the operator may open a tournament session of each of the plurality of games online in order to allow the members to participate in the tournament competition for each of the plurality of games online through electronic terminals held by the members.
In this regard,
As a result, the first user who completes the new user registration in the tournament game service accesses the service providing server 110 through the first electronic terminal 10 thereof to view a waiting room screen having a Ul illustrated in
In this case, when the first user clicks on the tournament session for the first game represented by reference numeral 211 through the first electronic terminal 10, the first electronic terminal 10 may transmit, to the service providing server 110 of the present disclosure, an access request command to the tournament session.
In this case, according to an exemplary embodiment of the present disclosure, the service providing server 110 as a component for processing an access request command to the tournament session received from the first electronic terminal 10 may further include a confirmation unit 119 and an access permission unit 120.
When the confirmation unit 119 receives an access request command to a tournament session (the tournament session means a session opened for users accessing the tournament session through the electronic terminal to play the first game jointly online) opened for a first game which is any one of the plurality of games, from the first electronic terminal 10 after the registration processing of the first transaction in the blockchain network 100 is completed, the confirmation unit 119 requests transmission of identification information for identifying the first user, to the first electronic terminal 10, and when receiving the first user identification information from the first electronic terminal 10, the confirmation unit 119 inquires the first NFT registered in the blockchain network 100 based on the first user identification information, and confirms the quantity of holding tickets of the first user recorded in the first profile table included in the first NFT.
In this regard, as in the above-described example, when it is assumed that the first user identification information ‘1SASzdfe342sdfsdadZ09dfaawer123sdaf’ is recorded as the owner information in the first NFT, and the quantity of ‘5’ is recorded in the first profile table included in the first NFT as the information on the ticket holding quantity of the first user, the confirmation unit 119 inquires the first NFT registered in the blockchain network 100 based on the first user identification information ‘1SASzdfe342sdfsdadZ09dfaawer123sdaf’ to confirm ‘5’ which is the information on the ticket holding quantity of the first user recorded in the first profile table included in the first NFT.
The access permission unit 120 confirms a first required number which is the number of required tickets for participating in the tournament of the first game by referring to the game information storage unit 111, and when it is confirmed that the ticket holding quantity of the first user is equal to or more than the first required number, the access permission unit 120 permits the access to the tournament session of the first electronic terminal 10 to process the first electronic terminal 10 to access the tournament session.
In this regard, when it is assumed that information is stored in the game information storage unit 111 as in Table 1 above, the first game is referred to as ‘game 2’, and the quantity of holding tickets held by the first user is confirmed as ‘5’, the quantity of holding tickets held by the first user is equal to or more than ‘1’ which is the first required number for participating in the tournament for ‘game 2’, so the access permission unit 120 permits the first electronic terminal 10 to access the tournament session for ‘game 2’ to process the first electronic terminal 10 to access the tournament session.
Through this, the first user accesses the tournament session for the first game by using the first electronic terminal 10 to play the first game jointly with other users who access the tournament session in the form of the tournament online.
As such, when the access of the first electronic terminal 10 to the tournament session is permitted, the profile update unit 118 generates first tournament participation history information including date/time information at a current time and tournament information for the first game, and then generates a second traction indicating that the first tournament participation history information is new tournament participation history information for the first user, and at the same time, the first user exhausts tickets as large as the first required number, and register and process the second transaction in the blockchain network 100 to process the first tournament participation history information to be recorded in the first profile table included in the first NFT registered in the blockchain network 100, and at the same time, the quantity of holding tickets in the first profile table to be reduced and recorded by the first required number.
In this regard, as in the above-described example, when the first required number is ‘1’ as the first electronic terminal 10 accesses a tournament session for ‘game 2’, the profile update unit 118 generates first tournament participation history information including the date/time information at the current time and tournament information for ‘game 2’, and then generates a second traction indicating that the first tournament participation history information is new tournament participation history information for the first user, and at the same time, the first user exhausts tickets as large as ‘1’ which is the first required number, and register and process the second transaction in the blockchain network 100 to process the first tournament participation history information to be recorded in the first profile table included in the first NFT registered in the blockchain network 100, and at the same time, ‘5’ which is the quantity of holding tickets in the first profile table to be reduced by ‘1’ which is the first required number, and changed and recorded to ‘4’.
As a result, the first profile table shown in Table 3 above may be updated to Table 4 below.
In this case, according to an exemplary embodiment of the present disclosure, the profile update unit 118 may propagate the second transaction to the blockchain network 100 in order to register and process the second transaction in the blockchain network 100. Then, any one node of a plurality of nodes 101, 102, 103, 104, 105, and 106 constituting the blockchain network 100 may generate a block including the second transaction and propagate the generated block to the plurality of nodes 101, 102, 103, 104, 105, and 106. As a result, when the block is received in the plurality of nodes 101, 102, 103, 104, 105, and 106, the plurality of nodes 101, 102, 103, 104, 105, and 106 may record the first tournament participation history information in the first profile table of the first NFT included in the blockchain data stored in each node based on the second transaction in the received block, and at the same time, change and record ‘5’ which is the information on the quantity of holding tickets of the first user to ‘4’.
In this case, according to an exemplary embodiment of the present disclosure, upon receiving the access request command to the tournament session opened for the first game from the first electronic terminal 10, the service providing server 110 performs the certification for the first user, and then only when it is confirmed that the first user is a certified member, the service providing server 110 may further include a configuration of conducting a process for determining whether to allow the first electronic terminal 10 to access the tournament session based on the ticket held by the first user.
In this regard, the completion message transmission unit 116 may include a component which stores in predetermined certification information for certifying the first user in a member database (not illustrated) afterward in the process of completing the new user registration for the first user.
In this regard, as issuance of the first NFT for the first user is completed, when the registration completion message is transmitted to the first electronic terminal 10, the completion message transmission unit 116 may request transmission of a public key for electronic signature verification and e-mail address information held by the first user, to the first electronic terminal 10.
In this case, it is assumed that a predetermined first private key for an electronic signature and a first public key corresponding thereto are pre-stored in the first electronic terminal 10. As a result, when the first electronic terminal 10 receives a transmission request of the public key and the e-mail address information from the service providing server 110 of the present disclosure, the first electronic terminal 10 may receive, from the first user, information on a first e-mail address according to an account of the first user, and then, transmit, to the service providing server 110 of the present disclosure, the first public key stored in the first electronic terminal 10, and the information on the first e-mail address received from the first user.
As such, when the service providing server 110 of the present disclosure receives the first public key corresponding to the first private key pre-stored in the first electronic terminal 10, and the information on the first e-mail address from the first electronic terminal 10, the completion message transmission unit 116 may store, in the member database, the first user identification information, and the first public key and the information on the first e-mail address to correspond to each other.
In this case, according to an exemplary embodiment of the present disclosure, the confirmation unit 119 as a component for conducting user certification may include an event generation unit 123, a certification information generation unit 124, an operating unit 125, a signature request unit 126, a certification processing unit 127, and a confirmation processing unit 128.
The event generation unit 123 generates a certification event for conducting e-mail based user certification for the first user when receiving the access request command to the tournament session opened for the first game from the first electronic terminal 10.
The certification information generation unit 124 randomly generates, when the certification event is generated, a n (n is a natural number of 2 or more)-digit first certification number, randomly generates a certification value constituted by a natural number having a size of 9 or less, and then, performs a modulo operation having the certification value as a divisor for respective digit numbers constituting the first certification number to generate an n-digit second certification number.
For example, when n is ‘3’, the certification information generation unit 124 randomly generates a 3-digit first certification number as ‘642’, randomly generates the certification value as ‘5’, and then performs a modulo operation having ‘5’ which is the certification value as the divisor for ‘‘6’, ‘4’, and ‘2’ which are respective digit numbers constituting the first certification number to generate a 3-digit second certification number as ‘142’.
The operating unit 125 generates a column vector having respective digit numbers constituting the first certification number as components and a row vector having respective digit numbers constituting the second certification number as components, and operates a matrix multiplication between the column vector and the row vector to generate an operation matrix of an n×n size, and then operates Frobenius Norm of the operation matrix. Here, Frobenius Norm means L2-Norm that represents the size of the matrix.
In this regard, as in the above-described example, when the first certification number is generated as ‘642’ and the second certification number is generated as ‘142’ through the certification information generation unit 124, the operating unit 125 generates a column vector having respective digit numbers constituting ‘642’ which is the first certification number as components as
generates a row vector having respective digit numbers constituting ‘142’ which is the second certification number as components as ‘[1 4 2]’, and then operates the matrix multiplication between the column vector and the row vector to generate an operation matrix having a size of 3×3 as
and operate Frobenius Norm of the operation matrix.
The signature request unit 126 requests transmission of identification information for identifying the first user to the first electronic terminal 10, and when receiving the first user identification information from the first electronic terminal 10, confirms the first e-mail address stored to correspond to the first user identification information from the member database, sends a certification e-mail including the first certification number with the first e-mail address as a receiver, and then transmits the certification value to the first electronic terminal 10, and at the same time, requests the electronic signature based on the first certification number and the certification value.
For example, as in the above-described example, when the first certification number and the certification value are set to ‘642’ and ‘5’, respectively, the signature request unit 126 may request the transmission of the identification information for identifying the first user to the first electronic terminal 10, and when receiving the first user identification information from the first electronic terminal 10, confirms the first e-mail address stored to correspond to the first user identification information from the member database, and then send a certification e-mail including ‘642’ which is the first certification number with the first e-mail address as the receiver. Then, the signature request unit 126 may transmit ‘5’ which is the certification value to the first electronic terminal 10, and at the same time, request the electronic signature based on the first certification number and the certification value.
In this case, according to an exemplary embodiment of the present disclosure, upon receiving the electronic signature request from the service providing server 110 jointly with the certification value, the first electronic terminal 10 may display a message for requesting the first user to input the first certification number included in the certification e-mail received by an account according to the first e-mail address into the first electronic terminal 10.
In this case, when the first user inputs, into the first electronic terminal 10, the first certification number included in the certification e-mail received by the account according to the first e-mail address in response to the message, the first electronic terminal 10 performs the modulo operation having the certification value as the divisor for the respective digit numbers constituting the first certification number to generate the n-digit second certification number, and then generate a column vector having respective digit numbers constituting the first certification number as components and a row vector having respective digit numbers constituting the second certification number as components, and operates the matrix multiplication between the column vector and the row vector to generate the operation matrix of the n×n size, and then sign the Frobenius Norm of the operation matrix with the first private key for the first user stored in the first electronic terminal 10 to generate a first electronic signature value, and transmit the generated first electronic signature value to the service providing server 110 of the present disclosure.
In this regard, as in the above-described example, when the first certification number and the certification value are ‘642’ and ‘5’, respectively, the first electronic terminal 10 may display a message for requesting the first user to input the first certification number included in the certification e-mail received by the account according to the first e-mail address into the first electronic terminal 10 when receiving the electronic signature request from the service providing server 110 jointly with ‘5’ which is the certification value.
Then, the first user logs into the account according to the first e-mail address to confirm the certification e-mail, and confirms ‘642’ which is the first certification number included in the certification e-mail to input ‘642’ which is the first certification number into the first electronic terminal 10.
As such, when the first user inputs ‘642’ which is the first certification number included in the certification e-mail into the first electronic terminal 10, the first electronic terminal 10 performs a modulo operation having ‘5’ which is the certification value as the divisor for ‘‘6’, ‘4’, and ‘2’ which are respective digit numbers constituting the first certification number to generate a 3-digit second certification number as ‘142’.
Then, the first electronic terminal 10 generates a column vector having respective digit numbers constituting ‘642’ which is the first certification number as components as
and generates as a row vector having respective digit numbers constituting ‘142’ which is the second certification number as components as ‘[1 4 2]’, and then operates the matrix multiplication between the column vector and the row vector to generate an operation matrix of a 3×3 size as
Thereafter, the first electronic terminal 10 operates the Frobenius Norm of the operation matrix, and then performs the electronic signature for the Frobenius Norm based on the first private key pre-stored in the first electronic terminal 10 to generate the first electronic signature value and transmit the first electronic signature value to the service providing server 110 of the present disclosure.
Upon receiving the first electronic signature value in response to the electronic signature request from the first electronic terminal 10, the certification processing unit 127 extracts the first public key stored to correspond to the first user identification information from the member database, and then compares a value acquired by decoding the first electronic signature value based on the first public key and the Frobenius Norm of the operation matrix with each other, and when it is confirmed that both values coincide with each other, completes the certification for the first user.
When the certification for the first user is completed, the confirmation processing unit 128 inquires the first NFT registered in the blockchain network 100 based on the first user identification information to confirm the ticket holding quantity of the first user recorded in the first profile table included in the first NFT.
