[0033] According to an embodiment of the present invention, online activities include, but are not limited to, online games, portal services, and social network services (SNS). Furthermore, online games include various genres such as sports, massively multiplayer online role-playing games (MMORPGs), action online strategy games (AOS), first-person shooters (FPSs), trading card games (TCGs), and collectible card games (CCGs). Online games refer to games played in a competitive format between users and games played between users and a computer (e.g., AI). Of course, the types of online games are not limited to the above examples.

[0034] According to one embodiment of the present invention, a game providing device can acquire user information including HP information of a character corresponding to a user in a game service. The user information includes information related to the user's client tampering history. The game providing device can perform an operation to reduce the character's HP by a predetermined amount. The game providing device can determine whether client tampering has occurred by detecting whether there is a change in the character's HP information.

[0035] In one embodiment, the game providing device may receive a signal to end the game from a user. If the user desires to end the game, the game providing device may provide an interface allowing the user to input for ending the game. When the game providing device receives a signal to end the game from the user, the game providing device may determine client tampering by decreasing the character's HP by a predetermined amount. In one embodiment, the game providing device may determine client tampering by decreasing the character's HP by a predetermined amount at predetermined intervals while the user is using the game service. In one embodiment, the game providing device may set a period for performing the character's HP decrease operation.

[0036] According to one embodiment of the present invention, the game providing device may determine that client tampering has not occurred if a change in the character's HP information occurs due to an action to decrease the character's HP. In one embodiment, the game providing device may determine that client tampering has occurred if a change in the character's HP information occurs due to an action to decrease the character's HP. If the game providing device determines that client tampering has occurred, it may restrict the user's use of the game service. In one embodiment, the game providing device may determine a period for restricting the user's use of the game. In one embodiment, the game providing device may determine a level of restriction on the user's use of the game service based on a client tampering history included in the user information.

[0037] Hereinafter, a specific method for the game providing device to provide a game service will be described with reference to FIG. 2 and subsequent figures.

[0038] FIG. 2 is a diagram illustrating a method for determining whether a client has been tampered with according to an embodiment of the present invention.

[0039] Referring to Figure 2, the game providing device can determine whether a user has tampered with a client. In one embodiment, the game providing device can determine whether a user has tampered with a client based on HP information of a character corresponding to the user. Client tampering refers to a method in which a user sets a game character's HP so that it does not decrease in single-player genres such as action, RPG, and casual FPS, and can be used interchangeably with "invincible mode" in the present invention.

[0040] In one embodiment, the game providing device may acquire user information including HP information 210 of a character corresponding to a user. The HP information 210 corresponds to the physical strength of a character in a game service, and if the character's HP is depleted during game play, the character dies or undergoes a corresponding action. In one embodiment, if the character's HP is depleted, the user is penalized in the game service. For example, if the character's HP is depleted, the user loses any acquired goods or experience points.

[0041] In one embodiment, the user information includes, but is not limited to, information related to the user's client tampering history. The information related to the client tampering history refers to information related to whether the user tampered with the client while using a previous game service, and includes information related to the number of times the user tampered with the client. In one embodiment, the information related to the client tampering history includes information related to whether a user of the same account tampered with the client in another game. In one embodiment, the game providing device may determine a level of restriction on the user's use of the game service based on the information related to the client tampering history. Specific game service restrictions will be described below with reference to FIG. 6.

[0042] In one embodiment, the game providing device may reduce a character's HP by a predetermined amount based on the acquired user information. The game providing device may determine the amount of HP reduction for the character so as not to interfere with game operation. If the game providing device reduces the character's HP by an amount greater than the character's currently remaining HP, the character's HP will become 0. Therefore, the game providing device may determine the amount of HP reduction taking into account the currently remaining HP. For example, if the user's total HP is 615 and the character's current HP is 97, the user's character's HP will be reduced by 3 (220). In one embodiment, the game providing device may determine the amount of HP reduction taking into account the character's currently remaining HP. For example, if the user's HP is about 3, the game providing device may set the HP reduction to be an amount less than 1 so as not to interfere with game operation.

[0043] In one embodiment, the game providing device may receive a signal from a user to end the game. When the game providing device receives the signal from the user to end the game, the game providing device may perform an operation of reducing the character's HP by a predetermined amount. In one embodiment, the game providing device may perform an operation of reducing the character's HP by a predetermined amount at predetermined intervals. For example, the game providing device may perform an operation of reducing the character's HP every two hours during game play. Specific operations will be described below with reference to FIG. 4.

[0044] In one embodiment, the game providing device may restore the character's HP after determining whether the user has tampered with the client by an amount equal to the amount of HP that was reduced to determine whether the user has tampered with the client. For example, if the game providing device reduces the character's HP by 3 and then determines that the user has not tampered with the client, the game providing device may restore the character's HP by 3.

[0045] In one embodiment, the game providing device can detect whether there is a change in the HP information of a character based on the user's action of reducing HP. The game providing device can determine whether the client has tampered with the client based on the detection result. For example, if the game providing device reduces the user's HP by about 3 but there is no change in the HP amount, the game providing device determines that the user has tampered with the client. If there is a change in the HP amount due to the game providing device's action of reducing the user's HP, the game providing device determines that the user has not tampered with the client. Specific examples will be described below with reference to FIG. 5.

[0046] In one embodiment, if the game providing device determines that client tampering has occurred, it can restrict the user's use of the game service. The game providing device can determine a game service usage restriction level based on user information. For example, the game service usage restriction level can be determined based on whether the user has previously tampered with the client or the number of times the user has tampered with the client. Specific game service usage restrictions will be described below with reference to FIG. 6.

[0047] FIG. 3 is a flowchart illustrating a method for determining client tampering according to an embodiment of the present invention.

[0048] Referring to FIG. 3, the operation performed by the game providing device to determine whether a user's client has been tampered with is disclosed.

[0049] In step S310, the game providing device may acquire user information including HP information of a character corresponding to the user on the game service, The user information includes any information related to the user on the game service.

[0050] In one embodiment, the game providing device may acquire all information generated by a user's use of the game service. The user information may include HP information. HP information is information corresponding to a character's health in the game service, and may include, but is not limited to, information related to the character's total HP, the character's current HP, the amount of HP lost due to client tampering, the amount of HP lost due to damage, or the amount of HP recovered by an item. In one embodiment, the user information may include information related to the user's client tampering history. The information related to the client tampering history may include information related to whether the user has tampered with the client while using the game service, and, if the user has tampered with the client, information related to the number of times the user has tampered with the client.

[0051] In step S320, the game providing device may perform an operation of decreasing the HP of the character by a predetermined amount based on the user information. The game providing device may decrease the HP of the character based on the user information acquired in step S310.

[0052] In one embodiment, the game providing device may determine or change the amount of HP of a character to be reduced. The game providing device may determine the amount of HP of a character to be reduced based on user information. If the character's current HP is low, the amount of HP to be reduced may be small enough to not interfere with game operation. For example, if the character's current HP remaining is about 5, the character's HP may be reduced by an amount of 1 or less to prevent the character from dying. In one embodiment, the game providing device may determine the amount of HP to be reduced, taking into account the character's HP at the time the client tampering action is performed.

[0053] In one embodiment, the game providing device may perform an operation of reducing the HP of a character when receiving a signal from a user to end the game. The game providing device may perform an operation of reducing the HP of a character in step S320 to determine whether the user has tampered with the client before ending the game. In one embodiment, the game providing device may perform an operation of reducing the HP of a character at predetermined intervals. The game providing device may set a period to check whether the user has tampered with the client at certain intervals. For example, the game providing device may perform an operation of reducing the HP of a user every two hours.

[0054] In step S330, the game providing device may detect whether there is a change in the HP information of the character based on the action of decreasing the HP of the character. The game providing device may detect whether there is a change in the HP information of the character based on the action of step S320.

[0055] In one embodiment, the game providing device may detect whether a character's HP has decreased by a predetermined amount based on the character's HP information included in the user information.

[0056] In one embodiment, when a character's HP is reduced by an action to reduce the character's HP, the game providing device may perform an action to restore the reduced HP. When a character's HP is reduced by an action to reduce the character's HP for determining client tampering, the game providing device may restore the reduced HP for normal game operation. For example, when a character's HP is reduced by 3 and the game providing device detects that the character's HP has been reduced by 3 due to the action, the game providing device may restore the character's HP by 3.

[0057] In step S340, the game providing device may determine whether the client has been tampered with based on the detection result. The game providing device may determine whether the user has tampered with the client based on step S330.

[0058] In one embodiment, if the game providing device detects a change in the HP information of a character due to an action to decrease the character's HP, it may determine that the user has not tampered with the client. If the game providing device detects no change in the HP information of a character due to an action to decrease the character's HP, it may determine that the user has tampered with the client. If the character's HP does not decrease despite an action to decrease the character's HP, the game providing device may determine that the user has tampered with the client, i.e., used the game service in invincible mode.

[0059] In one embodiment, if the game providing device determines that a user has tampered with a client, the game providing device may restrict the user's use of the game service. The game providing device may restrict the user's use of the game service for a user who has fraudulently used the game service through client tampering. For example, the game providing device may restrict the user's access to the game for a certain period of time or restrict the user from connecting to the game using the ID.

[0060] In one embodiment, the game providing device may determine a level of restriction on game service use for a user who has tampered with a client based on user information, including information on the user's client tampering history, including, but not limited to, information on whether the user has tampered with a client while using the game service or information on the number of times the user has tampered with a client.

[0061] In one embodiment, the user information includes information regarding whether the user has tampered with a client in another game using the same account. For example, even if a user is currently playing game "A," the game providing device may acquire information regarding whether the user has tampered with a client in another game using the same account. The game providing device may determine the level of restriction on the user's use of the game service based on the acquired information.

[0062] If a particular user tampers with the client multiple times, the game providing device may restrict the user's use of the game service. For example, if a user tampers with the client once, the game providing device may restrict the user's use of the game service for one week, or may reset the goods and experience points acquired through the game service on that date. If the user tampers with the client twice, the game providing device may impose stronger restrictions on the user. The game providing device may restrict a user who tampers with the client more than a predetermined number of times from using the game service at all. A specific example will be described below with reference to FIG. 6.

[0063] FIG. 4 is a diagram illustrating a method for determining whether a client has been tampered with based on a game end signal according to an embodiment of the present invention.

[0064] Referring to FIG. 4, the game providing device can receive a signal to terminate the game service from the user, and can perform an operation to determine whether the client has been tampered with based on the signal.

[0065] In one embodiment, the game providing device may receive a signal 410 from a user indicating that the user wishes to end the game. When the game providing device receives the signal 410 to end the game from the user, the game providing device may perform an operation to determine whether the client has been tampered with. When the game providing device receives the signal to end the game, the game providing device may perform an operation to reduce the HP of the character by a predetermined amount.

[0066] In one embodiment, the game providing device may reduce a character's HP 420 by a predetermined amount 430 to determine whether a client has tampered. In one embodiment, the game providing device may set the amount of HP to be reduced to determine whether a client has tampered. The game providing device may set the amount of HP to be reduced to based on the character's HP information. In one embodiment, the HP information is information corresponding to the character's physical strength in the game service, and may include, but is not limited to, the character's total HP, the character's current HP, the amount of HP to be reduced due to client tampering, the amount of HP reduced due to in-game damage, or the amount of HP recovered by an item. For example, if a character's HP is about 4, the HP may be reduced by a small amount (e.g., a value less than 1) to prevent the character from dying.

[0067] In one embodiment, the game-providing device may perform an operation of reducing the HP of a character to determine whether a client has been tampered with at a predetermined interval. The game-providing device may set a period for performing the operation of reducing the HP of a character to periodically check for client tampering, not just when receiving an end signal. For example, the game-providing device may perform the operation of reducing the HP of a character every two hours. In one embodiment, the game-providing device may determine the period based on client tampering history information included in the user information. For example, for a user who has a history of client tampering, the game-providing device may perform the operation of reducing the HP of a character at more frequent intervals to check for client tampering.

[0068] In one embodiment, the game providing device may detect whether there is a change in HP information due to an action that reduces the HP of a character. The game providing device may determine whether a user has tampered with a client based on the detection result. In one embodiment, if the game providing device determines that a user has tampered with a client, it may restrict the user from using the game service. In one embodiment, the game providing device may determine a level of restriction on the user who has tampered with a client based on client tampering history information included in the user information. A specific example is shown in FIG. 6.

[0069] In one embodiment, if a character's HP fluctuates due to an action that reduces the character's HP and it is determined that client tampering has not been performed, the game providing device may restore the character's HP to the extent that it has been reduced.

[0070] FIG. 5 is a diagram illustrating a specific method for determining whether a client has been tampered with according to an embodiment of the present invention.

[0071] 5, the game providing device can acquire user information including the HP information of the character, and can determine whether the client has been tampered with based on the HP information of the character.

[0072] In one embodiment, the game providing device may perform an operation of reducing the HP of a character by a predetermined amount 510 to determine whether client tampering has occurred. The game providing device may determine the amount of HP to reduce based on the character's HP information. For example, if a character's total HP is 615 and its current HP is 97, the game providing device may reduce the character's HP by 5. The game providing device may determine the amount of HP to reduce so that the character's HP does not reach 0. In one embodiment, after determining client tampering, the game providing device may restore the character's HP by the amount of the reduced HP.

[0073] In one embodiment, the game providing device may determine whether a user has tampered with a client based on an action to reduce a character's HP. The game providing device may detect whether there is a change in the character's HP information based on the action, and determine whether client tampering has occurred based on the detection result. In one embodiment, the game providing device may determine that client tampering has occurred if there is no change in the character's HP information based on the action to reduce the character's HP. For example, if a character's HP is reduced by about 5 from 97, but the character's HP information remains at 97 without any change (520a), the game providing device may determine that the user has tampered with a client.

[0074] In one embodiment, the game providing device may determine that client tampering has not occurred if there is a change in the character's HP information due to an action to decrease the character's HP. For example, if the character's HP is decreased from 97 to 92 due to an action to decrease the character's HP by about 5 (520b), the game providing device may determine that the user has not tampered with the client and has used the game service normally.

[0075] In one embodiment, the game providing device can determine whether a client has been tampered with based on the character's HP information and restrict the user from using the game service. Game service restrictions will be described below with reference to FIG.

[0076] In one embodiment, when a character's HP is reduced by an action of reducing the character's HP, the game providing device may perform an action of restoring the reduced HP. When a character's HP is reduced by an action of reducing the character's HP for determining client tampering, the game providing device may determine client tampering and then restore the reduced HP.

[0077] FIG. 6 is a diagram illustrating a method for restricting use of a game service when a client is tampered with, according to an embodiment of the present invention.

[0078] Referring to FIG. 6, if the game providing device determines that a client has been tampered with, it can restrict the user from using the game service.

[0079] In one embodiment, the game providing device may determine whether a client has been tampered with based on the character's HP information. If the game providing device determines that a user has tampered with a client, it may restrict the user's use of the game service. In one embodiment, the game providing device may restrict (610) the user's access to the game service for a certain period of time. For example, if the game providing device determines that a particular user has tampered with a client as the user finishes a game at 15:45 on April 6, 2024, it may restrict the user's use of the game service for one week. If the user attempts to reconnect to the game service, the game providing device may notify the user that their game use has been restricted due to a violation of the operating policy. The game providing device may also notify the user of information regarding the date and time when the game use restriction will be lifted (15:45 on April 13, 2024).

[0080] In one embodiment, the game providing device can notify the user of the reason why the user's use of the game service has been restricted. For example, the game providing device can provide information so that the user can check the reason for the restriction on game use on their personal page.

[0081] In one embodiment, the game providing device may initialize the goods and experience points acquired through game play on the date on which the user is determined to have tampered with the client. For example, the game providing device may initialize the experience points, items, goods acquired while using the game service in invincible mode, and information related to quests completed by the user through the tampered client.

[0082] In one embodiment, the game providing device may determine a level of restriction on a user's use of the game service based on user information, including information on the user's client tampering history, including, but not limited to, information on whether the user has a history of client tampering, information on the number of times the user has tampered with the client, etc.

[0083] In one embodiment, the information regarding the client tampering history includes information regarding whether a user of the same account has a history of client tampering in another game. For example, even if a user plays game "A," the game providing device may use history information regarding whether the user has performed client tampering in game "B" with the same account.

[0084] The game providing device can determine the level of restriction on the use of game services for a user based on information related to the client tampering history. For example, a user who has tampered with a client once can be restricted from using the game service for one week. The game providing device can impose stronger restrictions on a user who has tampered with a client multiple times. In one embodiment, the game providing device can use whether or not the user has a history of client tampering in other games to determine the level of restriction on the use of game services for the user.
