[Problems to be solved by the invention]
In such a network game, the player's malicious intentions such as “when the result of the session does not match the player's intention, the game device is turned off or reset to invalidate the session itself”. An act may be performed. In order to maintain the morality within the game world, it is desirable to detect and prevent such illegal acts as much as possible. However, it is difficult for only the server device to detect such an illegal act performed on the player's terminal device side. Therefore, a technique for detecting such fraudulent acts is strongly desired.
[0004]
The present invention has been made to solve such a problem, and is suitable for preventing a malicious act of a player as much as possible, a score system, a terminal device, a server device, a terminal method, a server method, and the above. An object is to provide a program realized by a computer.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, the following invention is disclosed in accordance with the principle of the present invention.
[0006]
The score system according to the first aspect of the present invention includes a server device and a terminal device, and is configured as follows. The server device and the terminal device communicate with each other by sending and receiving various messages. However, the “message” does not necessarily mean only a character string, but various data including binary data, various commands / It also includes commands and various signals.
[0007]
That is, the terminal device includes a start message transmission unit and a session storage unit, the start message transmission unit transmits a start message to start a session to the server device, and the session storage unit stores the session. The start is stored in a nonvolatile manner. Thus, the fact that each session has been started is managed on the terminal device side.
[0008]
Here, “non-volatile storage” includes, for example, storage in an EEPROM (Electrically Erasable Programmable Read Only Memory), a non-volatile storage medium such as a hard disk or a flexible disk. Moreover, in today's electrical appliances, a mode is adopted in which the main power switch determines whether or not to supply power at all, while the sub power switch switches the main body to a standby state to reduce power consumption. In this standby state, the stored contents are not erased. For example, it is a case where it is stored in a RAM (Random Access Memory) with a power backup. In addition, there are two stages for resetting the terminal device. Normally, the contents stored in a specific area in the storage area are maintained as they are (so-called “soft reset”), and all the contents in the storage area are obtained by a predetermined operation. When the area is cleared (so-called “full reset”), storing in an area that is not erased by soft reset is also included in “nonvolatile storage”.
[0009]
On the other hand, the server device includes a start message reception unit, a score calculation unit, an end message transmission unit, and a score storage unit. The start message reception unit receives a start message transmitted from the terminal device, and receives a score. The calculation unit starts the session specified in the received start message and calculates the score for the session, and the end message transmission unit terminates the session to the terminal device when the session ends. When the session ends, the score storage unit stores the session and the score calculated for the session in association with each other. Therefore, techniques for various battles, trading, and problem solving in a known game system can be applied to the score calculation process from the start to the end of the session. On the other hand, the score storage unit calculates a score calculated for the session, and corresponds to the score of the player using the terminal device in the session.
[0010]
The terminal device further includes an end message receiving unit, the end message receiving unit receives the end message transmitted from the server device, and the session storage unit ends the session related to the received end message. Further store in nonvolatile. That is, the fact that the session is ended is also managed on the terminal device side.
[0011]
On the other hand, the terminal device further includes a session inspection unit and an abnormal termination transmission unit, and the session inspection unit, when a predetermined condition is satisfied, out of the sessions stored in the session storage unit in a nonvolatile manner, It is checked whether there is a record that the start is recorded and that the end of the session is not recorded (hereinafter referred to as “abnormal end session”), and the abnormal end transmission unit has an abnormal end session as a result of the inspection. In the case, the abnormal termination message specifying the abnormal termination session is transmitted. In other words, if the abnormal termination occurs by comparing the start information and end information of the session managed by the terminal device, it is considered that there has been an illegal act by the player, and this is reported to the server device.
[0012]
Further, the server device further includes an abnormal termination receiving unit and a score updating unit, the abnormal termination receiving unit receives the abnormal termination message transmitted from the terminal device, and the score updating unit receives the abnormal termination received A predetermined penalty score is used instead of the score stored in association with the abnormal end session specified in the message. That is, if abnormal termination has occurred, “predetermined penalty score” is used instead of “calculated score” as the score for the user in the session in the subsequent processing. In order to prevent a player's fraud, it is desirable that the “predetermined penalty score” is a value that is less preferred by the player than the “calculated score”.
[0013]
According to the present invention, a fraudulent act such as power off or reset when the result of a session is not favorable for the player can be detected on the terminal device side to prevent such a fraudulent act as much as possible.
[0014]
In the score system of the present invention, the storage medium for storing the session and the score is not necessarily provided in the server device, and is disposed on the terminal device side, and the score or the like is placed on the terminal device side by instruction control from the server device. It can be configured to be stored and updated on the terminal device side. According to the present invention, the score can be distributedly managed by the terminal device by instruction control from the server, instead of centrally managing the score by the server.
[0015]
Further, in the score system of the present invention, the session inspection unit can be configured to perform inspection on the assumption that a predetermined condition is satisfied when the terminal device starts operation. In other words, the abnormal end check of the session is performed when the game apparatus is turned on and the game is started, or when the game apparatus is reset and the game is started. In addition, the session inspection unit can be configured to perform an inspection before the start message transmission unit transmits a new session start message. That is, before starting a new session, first, it is checked whether fraud has been performed in an existing session.
[0016]
According to these inventions, it becomes possible to detect whether or not the player is not cheating at an appropriate timing on the terminal device side.
[0017]
Further, in the score system of the present invention, the session storage unit further stores “to end the session related to the received end message” in a nonvolatile manner, and “starts the session related to the received end message” The session inspecting unit deletes “to do” from itself, and among the sessions stored in a non-volatile manner in the session storage unit, the fact that the session is to be started is stored and the fact that the session is to be terminated is not recorded Instead of “a session in which the session storage unit stores the fact that the session is to be started in a nonvolatile manner” is set as an “abnormal end session”, the presence / absence of the session can be checked. That is, only the session start information is stored in the session storage unit, and when the session is ended, the session start information is deleted from the session storage unit.
[0018]
According to the present invention, even if a device has a limited storage capacity, such as an external memory used in a game device, session information can be managed on the terminal side to check for abnormal termination.
[0019]
A terminal device according to another aspect of the present invention is a terminal device of the score system. A server device according to another aspect of the present invention is a server device of the score system.
[0020]
A terminal method according to another aspect of the present invention communicates with a server device, and transmits a start message transmission step, a session start storage step, an end message reception step, a session end storage step, a session inspection step, and an abnormal end transmission. The process is comprised as follows.
[0021]
That is, in the start message transmission step, a start message to start the session is transmitted to the server device. In the session start storage step, information to start the session is stored in a nonvolatile manner. In the end message reception step, the server device is stored. In the session termination storage step, the fact that the session related to the received termination message is terminated is further stored in a nonvolatile manner.
[0022]
Further, in the session inspection process, when a predetermined condition is satisfied, among the sessions stored in the nonvolatile memory, information indicating that the session is started is stored, and information indicating that the session is ended is not recorded (hereinafter, “ In the abnormal termination transmission step, if there is an abnormal termination session, an abnormal termination message designating the abnormal termination session is transmitted.
[0023]

[0048]
(Score system outline configuration)
FIG. 2 is a schematic diagram showing a schematic configuration of the score system according to the present embodiment. Hereinafter, a description will be given with reference to FIG.
[0049]
In the score system 201, a plurality of terminal devices 211 and a server device 231 are connected via the Internet 251. In a competitive network game, a game is played between players using each terminal device 211, winning or losing is determined, a predetermined score is given to the winner, and a predetermined deduction is given to the loser As a matter of course, the game corresponds to “session”, and the score and deduction points correspond to “score”. In addition, in the network game of buying and selling or item exchange type, currency and items are exchanged in the game world, or items are exchanged. This increases or decreases the number of currencies and items owned by each player. Such trading / exchange is equivalent to a “session”, and an increase / decrease in the number corresponds to a “score”. Furthermore, in a problem-solving network game, a player is given a certain task, and various parameters increase or decrease depending on whether or not the problem can be solved. Is equivalent to.
[0050]
FIG. 3 is an explanatory diagram showing message exchange between each terminal device 211 and the server device 231. FIG. 3A shows message exchanges from the start to the end of the session. Hereinafter, a description will be given with reference to FIG.
[0051]
First, a session start message 301 is transmitted from each terminal device 211 to the server device 231. When the server device 231 receives the session start message 301, the server device 231 starts the session. If necessary, the server device 231 exchanges a message (indicated by a dotted arrow in the figure) necessary for the session progress with the terminal 211. Continue processing until the session ends. When the session ends, the server device 231 calculates a score for the player of each terminal device 211 and transmits a session end message 302 to each terminal device 211. Each terminal device 211 receives the session end message 302 and, if necessary, displays a score as a result of the session, various parameters obtained by accumulating the scores, and the like.
[0052]
FIG. 3B shows message exchanges when it is found as a result of the examination in the terminal device 211 that the session has ended abnormally. Hereinafter, a description will be given with reference to FIG. When abnormal termination is detected by the terminal device 211, an abnormal termination message 303 is transmitted to the server device 231. Upon reception of the abnormal termination message 303, the server device 231 searches for a score that has been calculated and stored in correspondence with the session specified in this, and uses the “penalty score” in the subsequent processing in place of the score. I decided to. In addition, a penalty message 304 notifying that a penalty has been imposed is transmitted to the terminal device 211. Upon receiving the penalty message 304, the terminal device 211 reports to the player that a penalty has been imposed.
[0053]
Below, the structure of the terminal device 211 of this embodiment and the server apparatus 231 is demonstrated in detail.
[0054]
(Terminal device)
FIG. 4 is a schematic diagram illustrating a schematic configuration of the terminal device 211 of the score system. FIG. 5 is a flowchart showing the flow of terminal session processing executed by the terminal device 211. FIG. 6 is a flowchart showing the flow of the terminal abnormality detection process executed by the terminal device 211 of the score system. Hereinafter, description will be given with reference to these drawings.
[0055]
The terminal device 211 communicates with the server device 231, and includes a start message transmission unit 401, a session storage unit 402, an end message reception unit 403, a session inspection unit 404, and an abnormal end transmission unit 405.
[0056]
First, terminal session processing will be described. This is a process executed in the terminal device 211 from the start to the end of a certain session, and is typically started when the player inputs an instruction to the game device 100 to start the session. The
[0057]
When the terminal session process is started, first, the start message transmission unit 401 transmits a start message to start the session to the server device 231 (step S501). The start message includes the communication identifier (IP address, MAC address, etc.) of the game device, the player identifier (user name at the contract provider, character name operated by the player, etc.), etc. Various types of information such as whether to conduct a session with a proper content (buying or selling, exchange, battle, problem solving, etc.) can be included. Accordingly, the CPU 101 functions as the start message transmission unit 401 in cooperation with the NIC 109.
[0058]
On the other hand, the session storage unit 402 stores in a nonvolatile manner that the session is started (step S502). Information stored in a nonvolatile manner can include the content of the start message, the time when the start message is transmitted, and the like. In an embodiment in which session processing proceeds after a response indicating that a session is started from the server device 231 in response to the start message, the session identifier specified in the response may be included. Therefore, a storage device such as the external memory 106 or a hard disk functions as the session storage unit 402.
[0059]
Thereafter, depending on the type of session, the terminal device 231 and other terminal devices 211 communicate with each other as appropriate to perform various processes (indicated by dotted arrows in the flowchart). The end message transmitted from the device 231 is received (step S503). In general, the end message includes information for identifying a session. Further, information such as a score calculated for the session and various parameters for the player may be included. However, depending on the type of game, the number of available sessions may be one at a time. In this case, it may be simply a notification that the current session has ended. Therefore, the CPU 101 functions as the end message receiving unit 403 in cooperation with the NIC 109.
[0060]
Then, the CPU 101 causes the session storage unit 402 to further store in nonvolatile information that the session related to the received end message is to be ended (step S504), and ends this processing. Therefore, in this embodiment, when a session is normally started and ended, both start information and end information for the session are stored in the session storage unit 402.
[0061]
On the other hand, if the user turns off the power of the game apparatus 100, resets it, or removes the external memory 106 in the middle of completing the session after the session is started, the session storage unit 402 stores Only the start information of the session is stored. At this time, the session is referred to as an “abnormal end session”. In the terminal abnormality detection process described below, this property is used to detect whether the session has ended abnormally.
[0062]
The terminal abnormality detection process is triggered by the following event.
(1) When the game apparatus 100 is turned on and a game program is loaded and executed.
(2) When the game apparatus 100 is reset and the game program is loaded and re-executed.
(3) In step S501, before attempting to transmit a session start message to start a new session.
(4) When no instruction is input from the player for a certain period of time while the session is not being performed during the game.
In all these cases, the terminal abnormality detection process may be executed, or any one of them may be selected and executed.
[0063]
When the terminal abnormality detection process is started, the session inspection unit 404 examines the session storage unit 402 and inspects whether there is an abnormal termination session (step S601). In the present embodiment, as described above, the start information of a session is stored, but when the end information of the session is not stored, an abnormal end session exists. Therefore, the CPU 101 functions as the session inspection unit 404 in cooperation with the external memory 106 and the like. As a result of the inspection, if there is no abnormal termination session (step S601; No), this process is terminated.
[0064]
On the other hand, when there is an abnormal end session (step S601; Yes), the abnormal end transmission unit 405 transmits an abnormal end message specifying the abnormal end session (step S602). The abnormal termination message needs to include information for identifying the abnormal termination session. Therefore, the CPU 101 functions as the abnormal end transmission unit 405 in cooperation with the NIC 109.
[0065]
And the penalty message transmitted from the server apparatus 231 is received (step S603). As will be described later, the server device 231 determines whether the abnormal termination session is caused by the terminal device 211 or the server device 231. If it is the former, the penalty message specifies that a penalty score has been imposed on the player. In the latter case, description information for the session is appropriately designated.
[0066]
Next, information on the penalty message is displayed to the player (step S604), and the session start information and end information stored in the session storage unit 402 are deleted as necessary, and the contents of the session storage unit 402 are organized. After securing a storage area that will be used in the subsequent processing (step S606), the present processing is terminated.
[0067]
Note that session start information is stored in the session storage unit 402 in a nonvolatile manner, but a mode in which the session start information is deleted from the session storage unit 402 after receiving a session end message may be employed. In this case, when the start information is stored in the session storage unit 402, the session is an abnormal end session.
[0068]
(Embodiment of server device)
FIG. 7 is a schematic diagram showing a schematic configuration of the server device of the score system. FIG. 8 is a flowchart showing the flow of server session processing executed in the server device. FIG. 9 is a flowchart showing a flow of server abnormality detection processing executed in the server device. Hereinafter, description will be given with reference to these drawings.
[0069]
The server device 231 communicates with the terminal device 211, a start message reception unit 701, a score calculation unit 702, an end message transmission unit 703, a score storage unit 704, an abnormal end reception unit 705, and a score update unit 706. . Here, the server device 231 takes a form in which the NIC 109 waits for reception of various messages transmitted from each terminal device 211. Therefore, after receiving the message, the contents of the message are scrutinized to determine the type of the message. If it is a session start message, server session processing is started, and if it is an abnormal end message, a server error is detected. The process is started, and if it is another message, the process corresponding to the message is executed.
[0070]
First, when the server session process is started, the start message receiving unit 701 receives the start message transmitted from the terminal device 211 (step S801). The start message received via the NIC 109 is expanded in the RAM 103, the contents are examined, and various session processes are executed according to the contents (indicated by dotted arrows in the figure). . At this time, communication with the terminal device 211 may be performed as appropriate. Moreover, the aspect which notifies a terminal device that the session was received with the identifier attached | subjected to the said session is employable.
[0071]
Then, the score calculation unit 702 starts a session specified by the received start message, and calculates a score for the session (step S802). As described above, the score calculation method is determined according to the game type and specifications. Therefore, the CPU 101 functions as the score calculation unit 702.
[0072]
When the session ends, the end message transmission unit 703 transmits an end message indicating the end of the session to the terminal device 211 (step S803). Although it is desirable to include an identifier for distinguishing the ended session in the end message, as described above, such an identifier may not be necessary depending on the type of game. Therefore, the CPU 101 functions as the end message transmission unit 703 in cooperation with the NIC 109.
[0073]
Next, the score storage unit 704 stores the session and the score calculated for the session in association with each other (step S804), and ends the process. Information sufficient to identify the person affected by the cumulative addition by the score, such as the identifier assigned to the session, the identifier of the terminal that started the session, and the identifier of the player who started the session are stored as session information. Will be. Therefore, typically, the hard disk included in the server device 231 functions as the score storage unit 704.
[0074]
On the other hand, when the server abnormality detection process is started, the abnormal termination receiving unit 705 receives the abnormal termination message transmitted from the terminal device 211 (step S901). Therefore, the CPU 101 functions as the abnormal end reception unit 705 in cooperation with the NIC 109. As described above, the abnormal termination message includes information for identifying a session that has terminated abnormally.
[0075]
Next, the score update unit 706 checks whether the abnormal end session specified in the received abnormal end message is stored in the score storage unit 704 (step S902), and if it is stored (step S902; Yes), the score The update unit 706 stores a predetermined penalty score in place of the associated and stored score (step S903), transmits a penalty message indicating that to the terminal device 211 (step S904), and performs this processing. finish. Therefore, the CPU 101 functions as the score update unit 706 in cooperation with a hard disk or the like.
[0076]
If it is not stored (step S902; No), the session has ended abnormally because it is considered that the session ended abnormally, not due to the player's fraud, but due to a malfunction of the server device 231. However, a penalty message indicating that no penalty is imposed is transmitted to the terminal device 211 (step S905), and this process is terminated.
[0077]
