However, the present invention may be embodied in many different forms and is not limited to the embodiments described herein. And in order to clearly explain the present invention in the drawings, parts irrelevant to the description are omitted, and similar reference numerals are attached to similar parts throughout the specification.

Throughout the specification, when a part is said to be "connected" to another part, this includes not only the case where it is "directly connected" but also the case where it is "electrically connected" with another element interposed therebetween. . In addition, when a certain component is said to "include", this means that it may further include other components without excluding other components unless otherwise stated.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

However, prior to explaining this, the meaning of the terms used below is first defined.

Hereinafter, 'online game' refers to a game service in which a game client program and a game server program cooperate and execute each other while exchanging data over a network. In the following, a client program for executing such an online game will be described as a 'game client' and a server program as a 'game server'.

In addition, below, 'game object' indicates graphic objects that are arranged in the above-described game space and affect game results. In particular, it includes objects that are selected, moved, or whose state is changed under the player's control, that is, the player's control objects. For example, it may be a character of a roll playing game (RPG), a card of a card game, or a block of a puzzle game. In addition, among the graphic objects arranged in the game space described above and influencing the game result, an object that affects the game object controlled by the player, but is not controlled by the player and is automatically moved or whose state is changed by the setting of the game itself. may include For example, it may be a non-player character (NPC) in an RPG or a feature in a shooting game.

And 'item' is a game element used to improve the player's game performance, which at least temporarily improves the game performance ability of the control target controlled by the player among the game objects described above, or the player's performance among the game objects. At least temporarily degrades the game performance ability of objects that hinder game performance or game objects controlled by the opposing player, or additionally gives the player a chance to perform a game, perform a specific action in the game, or exercise a special ability. It may be a game object that is given or other game elements. Items can be sold within the game, and items can be exchanged, traded, or gifted between players. In particular, these items are optional elements in the game where whether or not to use them is determined according to the player's choice. Each item may have properties, and may include one or more parameters related to the ability of the game object improved by the item.

On the other hand, a 'character' is a fictional character appearing in the game space, and is an object controlled by each player and a subject that performs game operations. As will be described later, each character is visualized as a 2D or 3D graphic image and can be defined by various attributes. Here, the attribute of the character may include one or more parameters related to the character's ability.

Hereinafter, 'game setting values' may include various types of parameters required to run an online game. For example, parameters related to the above-described item properties or character properties may be included. Specifically, parameters for forward movement speed and backward movement speed of a specific character may be included in game setting values, respectively. Also, as a specific example, a forward movement speed when the corresponding character uses a booster item may be included in the game setting value.

In addition, the game setting values may include setting values related to the operation of the game, for example, 'system setting values' for the game play environment or the start time and end time of the game. Specifically, for example, when a unit game starts, it may include a set value indicating a state in which an input signal received from each player can be processed. At this time, the system setting value may be set so that the value is changed for each of two or more different viewpoints for the operation of the game. For example, the system setting value, which had a False value within 3 seconds from the start of the unit game, is changed to a value of True after 3 seconds, so that players can control the character only after 3 seconds have elapsed from the start of the unit game. .

In addition to the terms defined above, terms that require explanation are separately explained below.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a configuration diagram of an online game system according to an embodiment of the present invention, FIG. 2 is a block diagram showing the configuration of a game play device according to an embodiment of the present invention, and FIG. 3 is an embodiment of the present invention. It is a block diagram showing the configuration of the game providing device according to the example.

As shown in FIG. 1 , the online game system 100 may include a game play device 10 and a game providing device 20, and the game playing device 10 and the game providing device 20 may include a network N ) to communicate with each other.

At this time, the 'network (N)' includes a local area network (LAN), a wide area network (WAN), a value-added network (VAN), a personal area network (PAN), It can be implemented in all types of wired/wireless networks such as mobile radio communication network, Wibro (Wireless Broadband Internet), Mobile WiMAX, HSDPA (High Speed Downlink Packet Access) satellite communication network, LTE (long term evolution) network, etc. have.

Meanwhile, the game play device 10 is an information processing device used by each user (hereinafter referred to as 'player') who plays the game, and executes the above-described game client so that each player receives an online game service.

The game play device 10 may be implemented as a computer, portable terminal, television, wearable device, etc. capable of connecting to a remote server through a network N or connecting to other terminals and servers. Here, the computer includes, for example, a laptop, desktop, or laptop equipped with a web browser, and the portable terminal is, for example, a wireless communication device that ensures portability and mobility. , PCS(Personal Communication System), PDC(Personal Digital Cellular), PHS(Personal Handyphone System), PDA(Personal Digital Assistant), GSM(Global System for Mobile communications), IMT(International Mobile Telecommunication)-2000, CDMA(Code Division Multiple Access)-2000, W-CDMA (W-Code Division Multiple Access), Wibro (Wireless Broadband Internet), Smart Phone, Mobile WiMAX (Mobile Worldwide Interoperability for Microwave Access), etc. (Handheld)-based wireless communication device may be included. In addition, television may include IPTV (Internet Protocol Television), Internet TV (Internet Television), terrestrial TV, cable TV, and the like. Furthermore, a wearable device is a type of information processing device that can be worn directly on the human body, such as, for example, a watch, glasses, accessories, clothes, shoes, etc. can be connected with

Meanwhile, the game providing device 20 may be implemented as a server-client system with the game play device 10 described above, and may be implemented as a normal server accepting access of the game play device 10 . That is, the game providing device 20 serves to execute a game server that operates together with a game client that is installed and driven in the game play device 10 . The game providing device 20 may be implemented as a group of server systems such as one or more hardware devices for executing a game server, a load balancing device, and a database.

Accordingly, the game play device 10 and the game providing device 20 implement an online game service while continuously communicating through the network N.

At this time, the game server and the game client respectively driven in the game providing device 20 and the game playing device 10 form a session to exchange data so that each player can play the game using a different user account. Here, the user account may be a pre-registered user account for a player who has already completed the membership registration process, or a temporary one-time user account.

Execution of the online game may be initiated by establishing a session between the game server and the game client for each account, and execution may be stopped by disconnecting and ending the session.

More specifically, the game play device 10 may include a client execution unit 11 as shown in FIG. 2 . The client execution unit 11 executes a game client installed in the game play device 10 . At this time, the game client tries to connect to the game server as soon as it is executed. Accordingly, the client execution unit 11 requests the game providing device 20 to establish a session between the game client and the game server by executing the game client.

At this time, when the client execution unit 11 executes the game client, it may receive account information from the player. In this case, the client execution unit 11 may transmit the input account information to the game providing device 20, thereby requesting session establishment for a user account corresponding to the account information.

Meanwhile, when the client execution unit 11 executes the game client, it may not receive account information from the player. In this case, the client execution unit 11 may request the game providing device 20 to establish a session for a one-time temporary account.

In addition, the client execution unit 11 stops execution of the game client when the game providing device 20 releases the session established between the game client and the game server. In particular, when the cause of the session release is due to the sanction of the game providing device 20, the game providing device 20 releases the session and at the same time sends a sanction message (a message notifying that the player has been sanctioned and sends information about the sanction period). may be included) to the game play device 10, and the client execution unit 11 may display a sanction message to the player while stopping the execution of the game client.

Also, the game play device 10 may include a setting value processing unit 12 . The setting value processing unit 12 receives one or more game setting values, in particular, a game setting value selected as a tamper monitoring target (hereinafter referred to as 'tamper monitoring target game setting value') from the game providing device 20, the received game setting value. The set values are duplicated and stored in the game play device 10 . At this time, the game providing device 20 executes a game client and establishes a session between the game client and the game server, and then whenever a unit game (each game round) is started, a plurality of tamper-monitored game setting values are provided. The game setting value can be transmitted to the game play device 10, and the setting value processing unit 12 copies and stores it.

In addition, the game providing device 20 may repeatedly transmit game setting values to the game play device 10 after a unit game starts until it ends.

In addition, when a plurality of game setting values including game setting values subject to tamper monitoring are received from the game providing device 20, the setting value processing unit 12 may apply them to the game setting values of the game client.

In addition, the game play device 10 according to an embodiment of the present invention may include a setting value comparison unit 13 . The setting value comparing unit 13 compares the game setting value applied to the game client with the game setting value received from the game providing device 20 and copied and stored.

At this time, all of the game setting values transmitted by the game providing device 20 may be tamper monitoring targets, or only some of them may be tamper monitoring targets and may be compared in the setting value comparison unit 13. For example, when the game providing device 20 transmits a total of 50 parameters as game setting values, the game play device 10 may compare only 10 pre-selected parameters among them as game setting values subject to tamper monitoring.

In addition, the setting value comparing unit 13 compares the game setting value applied to the game client and the game setting value copied as it is transmitted by the game providing device 20, and the comparison result data including information on the type of parameters that do not match. can create Alternatively, based on information about the type or value of the parameter that does not match, it is possible to determine whether or not to modulate the game setting value, and to generate data as a result of comparing the information on whether or not to modulate. That is, the comparison result data may include a simple comparison result or may include a determination of whether to modify based on the simple comparison result.

In addition, the setting value comparison unit 13 obtains system setting values applied to the game client for at least two points of time, respectively, in relation to system setting values set to have different values for at least two different time points among game setting values. Thus, it can be transmitted from the game providing device 20 and compared with the copied and stored system settings. That is, by comparing system setting values for each time point and generating comparison result data, it is possible to detect modulation.

As an example, a system applied to a game client at one or more points in the range within 3 seconds from the start of the game, in relation to a system setting value set so that a value of False is maintained within 3 seconds from the start of the game and changed to a value of True after 3 seconds. You can check whether the setting value is changed to True in advance. In other words, according to the replicated system setting value, even the system setting value obtained at any point in time must remain False within the range of at least 3 seconds. can be the basis for determining that

In addition, the game play device 10 may transmit comparison result data generated by the setting value comparison unit 13 to the game providing device 20 . At this time, since the game providing device 20 in the embodiment of the present invention can transmit the game setting value to the game play device 10 when each unit game starts, the comparison result data is also the game providing device whenever each unit game starts. (20) can be passed. In addition, since the game providing device 20 may transmit game setting values to the game play device 10 several times from the start of each unit game until the end of each unit game according to the embodiment, the game providing device 20 Whenever new game setting values are provided to the game play device 10 , new comparison result data may be transmitted to the game providing device 20 .

In this way, since the game play device 10 side detects whether or not the game setting value of the game client is tampered with in real time while the game is in progress, whether or not hacking is determined, there is no need to develop and use a separate security program for each hacking program. You can minimize the effort to determine whether or not. In particular, since it detects not the hacking program that causes the game client tampering, but the tampering of the game settings itself, which is the result of using the hacking program, it has the advantage of being able to efficiently detect hacking caused by different causes. Furthermore, since game setting values subject to tamper monitoring can be appropriately selected according to hacking patterns and frequencies of players, resources required for hacking monitoring can be minimized.

Meanwhile, as shown in FIG. 3 , the game providing device 20 may include a session management unit 21 that establishes a session between a game server and a game client. When a game client is executed in the game play device 10, the game client forms a session with the game server and operates. A session can be selectively formed or rejected by referring to the stored sanction status information.

Sanction status information will be described later, but may be stored in association with each registered user account or each IP address of the game play device 10 using a one-time temporary account. When determining a sanction for a temporary account, the account information of each pre-registered user account including the sanction period or the IP address of the game play device 10 using the temporary account may be recorded.

Therefore, when the game play device 10 attempting access requests session formation for a registered user account, the session management unit 21 checks the sanction status of the user account and rejects the access if it falls within the current sanction period. can do.

Similarly, the session management unit 21 checks the IP address of the game play device 10 when the game play device 10 attempting access requests session formation using a one-time temporary account, and sanctions in relation to the IP address. If the status information is registered, the sanction status can be checked, and access can be rejected if it falls within the current sanction period.

However, when the session management unit 21 normally establishes a session with the game play device 10 that has attempted to connect, the server execution unit 22 executes the game server so that an online game can be played between the game client and the game server. let it commence That is, the server execution unit 22 is a component of the game providing device 20 that executes a game server.

Furthermore, the session management unit 21 terminates the session when the sanctions decision unit 26, which will be described later, determines the sanctions for the account corresponding to the game client that has already formed a session with the game server and is running. You can stop running the game server. That is, the session management unit 21 may immediately stop the bad player's game play by terminating the session formed between the game server and the game client in response to a real-time sanction measure to be described later.

Also, the game providing device 20 may include a setting value transmission unit 23 . The setting value transmitter 23 may transmit one or more game setting values to the game play device 10 when the execution of the online game starts. In this case, the game setting value may include a plurality of setting values necessary for playing the game, and at least some of the setting values among them may be the setting value selected as the above-mentioned setting value of the game to be monitored for tampering.

In particular, the set value transmission unit 23, after the online game is executed, when the online game is composed of a unit game, which is an independent game round that is distinguished from each other (for example, players wait in a waiting room and play a game group) If formed, game setting values may be transmitted to the game play device 10 every time a unit game is started (when a unit game is performed for the formed game group). In addition, the setting value transmitting unit 23 may repeatedly transmit game setting values to the game play device 10 after a unit game starts until it ends according to an embodiment. In particular, if it is determined that the game client has not been tampered with as a result of the determination of the tamper detection unit 24, which will be described later, and the unit game has not ended, game setting values may be transmitted to the game play device 10 again.

In addition, the game providing device 20 may include a tamper detection unit 24 that detects tampering based on the comparison result data when the above-described comparison result data is received from the game play device 10 . As described above, the comparison result data may include information on parameters having different values among the game setting value provided by the setting value transmission unit 23 and the game setting value applied to the game client. In this case, the tamper detection unit ( 24) may go through a process of determining whether or not to modulate again based thereon. In addition, when the comparison result data includes information on whether the game play device 10 has already determined whether or not it has been tampered with, the tamper detection unit 24 can immediately determine tampering of the game setting value by receiving it.

Meanwhile, the game providing device 20 according to an embodiment of the present invention may include a modulation/record management unit 25 . Whenever the tamper detection unit 24 detects tampering of the game client, the tamper record management unit 25 stores an account corresponding to a session formed between the game client and the game server (a one-time temporary account using a pre-registered user account and IP address). may include an account) and may store modulation records. That is, the tamper record management unit 25 may store the tamper record in association with the account information or IP address of a pre-registered user account. information may be included.

In addition, the game providing device 20 according to an embodiment of the present invention may include a sanction decision unit 26 . The sanction decision unit 26 may determine whether or not to sanction the game play device 10 when the above-described tamper detection unit 24 confirms tampering with the game setting value. In addition, the sanction decision unit 26 may also determine the sanction period when determining whether to sanction.

The sanction decision unit 26 may refer to the tamper record stored by the tamper record management unit 25 in determining whether or not to suspend the sanction and the sanction period. For example, the sanction decision unit 26 may not take a sanction action when tampering is detected for the first time in relation to an account for which tampering details are never recorded in the tampering record. However, in relation to an account that already has a history of tampering, it is possible to determine a sanction so that a disciplinary action is taken, and furthermore, a longer sanction period can be determined as the frequency of tampering increases.

When the sanction decision unit 26 determines whether or not to sanction and the sanction period, the sanction status information including information about whether or not to sanction and the sanction period is sent to the corresponding account (including pre-registered user accounts and one-time temporary accounts using IP addresses). It can be stored in association with the account information or IP address of the user.

On the other hand, the game providing device 20 according to an embodiment of the present invention can search and view the sanction status information stored by the sanction decision unit 26, which is for some administrators who have been granted access to the sanction state information. It may be allowed only for accounts. At this time, the administrator terminal (not shown) accessing the sanction status information of the game providing device 20 using the administrator account may be a general information processing device.

In this way, when tampering of the game client is confirmed, the game providing device 20 does not remove or block the hacking program that is executed in the game play device 10 and causes the tampering, but rather protects the player who uses the hacking program. By stopping the game play in real time, the players themselves can be induced to stop using and delete the hacking program.

In addition, since bad players are excluded from the game in real time by the game providing device 20, damage to good players can be prevented in advance and fairness of the game can be maintained. In particular, whenever a unit game is started, it is determined whether or not the game client of the players participating in the game has been tampered with, so damage to other players can be minimized.

In addition, for accounts that have been sanctioned after tampering with the game client, the sanction period is determined and managed, so game access can be blocked immediately without the need to determine tampering whenever a player using the account accesses the game again. . Therefore, each account can be managed efficiently. In particular, since players who do not use a pre-registered user account and use a temporary account such as an experience ID play the game using a new temporary account every time, conventionally, bad players who repeatedly tamper with the game client using the temporary account There was a problem that was difficult to sanction them. However, in the embodiment of the present invention, this problem can also be solved by the game providing device 20 managing the sanction status information for the players of these temporary accounts using IP addresses.

Hereinafter, a tamper detection method for a game client and a real-time game control method using the same will be described with reference to FIGS. 4 and 5 .

4 is a flowchart illustrating a tamper detection method and a real-time game sanctioning method using the same according to an embodiment of the present invention, and FIG. 5 is a process of providing sanction status information in a real-time game sanctioning method according to an embodiment of the present invention. It is an example diagram for explaining.

The tamper detection method and the real-time game control method according to the embodiment shown in FIG. 4 are time-sequential in the online game system 100, game play device 10, and game providing device 20 shown in FIGS. 1 to 3. Include steps to be processed. Therefore, even if the contents are omitted below, the contents described above with respect to the online game system 100, the game play device 10, and the game providing apparatus 20 shown in FIGS. It can also be applied to the tamper detection method and the real-time game sanctioning method according to the example.

As shown in FIG. 4 , the real-time game control method starts from step S111 in which a game client is executed in the game play device 10 and connection to the game providing device 20 is requested.

Accordingly, when the game play device 10 requests access using a pre-registered user account, the game providing device 20 uses the account information of the corresponding user account, or the game play device 10 provides a one-time temporary When access is requested using an account, the previously stored sanction status information is checked using the IP address (S121).

As a result of the check, if the account requested for access by the game play device 10 falls within the current restriction period (S122), the game providing device 20 rejects the access and ends the process.

However, in step S122, if it is determined that the account requested by the game play device 10 does not fall within the sanctions period, the game providing device 20 establishes a session between the game client running on the game play device 10 and the game server. It is formed (S131), and the game client and game server communicate with each other using the formed session so that the online game is executed (S132).

Meanwhile, the game play device 10 and the game providing device 20 cooperate with each other while executing the online game in step S132 to detect tampering of the game client (S133).

A specific process of performing step S133 for detecting tampering of the game client, that is, a tampering detection method, will be described later.

If tampering of the game client is detected in step S133, the game providing device 20 can immediately release the session established between the game client and the game server (S134) and terminate the execution of the online game (S135).

However, according to embodiments, the game providing device 20 may selectively perform a process of releasing the session and ending the execution of the game through a process of determining sanctions again, even if tampering is detected in step S133. That is, when tampering is detected, the game providing device 20 checks the previous tampering record of the account, and determines sanctions only when the number of tampering occurrences is greater than a preset value or when the tampering frequency occurring within a certain period is greater than a preset value. and may cause the game to terminate execution.

Subsequently, the game providing device 20 may store a modulation record for detected modulation in association with account information or an IP address of an account corresponding to a session formed between a game client and a game server (S126). Similarly, when a sanction is determined for a specific account, the game providing device 20 may store sanction status information including information on whether or not a sanction is imposed and a sanction period.

In this way, since whether or not the game client is tampered with is detected in real time and the corresponding player is immediately excluded from the game, damage to good players can be minimized and fairness of the game can be maintained. Accordingly, the number of players leaving the game can be minimized.

Here, looking at step S133, that is, the tamper detection method, while the game client and the game server cooperate to execute the online game (S132), the game providing device 20 can detect the start of a new unit game ( S123).

Accordingly, the game providing device 20 may transmit game setting values including game setting values subject to tamper monitoring to the game play device 10 whenever a new unit game is started (S124).

Meanwhile, the game play device 10 receiving the game setting values applies the received game setting values to the game client (S112), and at the same time copies and stores the game setting values provided from the game providing device 20 (S113). .

Subsequently, the game play device 10 compares the settings applied to the game client with the settings copied and stored in step S113 to generate comparison result data, and transfers the generated comparison result data to the game providing device 20. It is transmitted to (S115).

Accordingly, the game providing device 20 receiving the comparison result data detects whether or not the game client has been tampered with based on the comparison result data (S125).

At this time, if tampering of the game client is detected, as described above, in step S134, the session between the game client and the game server is released to end the game execution (S135).

However, if tampering of the game client is not detected in step S125, it is checked whether the unit game ends (S127), and steps S124 and S112 to S115 are repeatedly performed until the unit game ends, thereby tampering with the game client. The process of determining whether or not (S125) may be continued.

Meanwhile, if it is determined that the unit game is ended in step S127, the start of a new unit game is waited for again.

That is, in the tamper detection method according to an embodiment of the present invention, it is not to detect whether or not a hacking program is executed in the game play device 10, but to determine the main variables affecting game play according to the execution result of the hacking program. By using a method of detecting whether or not (game setting values) has changed, it is possible to determine whether hacking has occurred if major variables have been tampered with as a result of execution of any hacking program. This has the advantage of being able to detect hacking with minimal effort.

In particular, the effort required for hacking detection can be minimized by limiting the game setting values compared in step S114 to the preset tamper monitoring target game setting value, not all game setting values that can be applied to the game client. In this case, the tamper monitoring target The game setting value may be selected as a higher game setting value having a high modulation frequency based on the collected modulation records.

On the other hand, in such a tamper detection method and real-time game sanction method, a web page or a separate application is used as an administrator terminal (not shown) requesting sanction status information from the game providing device 20 to provide sanction state information. A step (not shown) may be further included, and an example thereof is shown in FIG. 5 .

Among one or more administrator accounts that can access the game providing device 20, there may be an administrator account to which access to sanction status information is granted, and the administrator terminal uses the administrator account to access the game providing device 20. You can request a search for sanction status information with In this case, a web page W as shown in FIG. 5 may be provided to the manager terminal.

The web page (W) may include an input interface (I) for inputting an identifier of a player to be searched. Also, an input interface P for setting a search target period may be included. When a manager sets an identifier of a search target player or a search target period and selects a search request button (S), a search result table (T) may be provided as shown.

The search result table T may include various field information included in sanction status information, and may include sanction period information such as sanction start time and sanction end time, and may include identification information of a player subject to sanction. . In addition, information on the type of modulation according to the modulated game setting value, the number of times the modifier is detected, the game type of the unit game in which the modifier is detected, and information about the virtual map or track applied to the unit game in which the modulator has occurred may be included. .

However, this is just an example, and the administrator can selectively search and view sanction status information according to search conditions, so that it can be used in the process of selecting or updating game setting values subject to tamper monitoring.
