1. Field of the Invention
The present invention relates to a technique for managing a game apparatus such as an arcade game apparatus or the like using encrypted information.
2. Description of the Related Art
There has been known a penny arcade where game apparatuses are set up to have arcadians enjoy playing games and to receive payments in exchange for services rendered from the arcadians. The manager of the penny arcade sets the arcade game apparatus and manages the penny arcade. However, in many cases, the manager does not always possess the game apparatuses. The manager is permitted (licensed) to merely operate the game apparatuses under conditions predetermined between the manager and a supplier (hereinafter referred to as manufacturer) for game apparatus and game software. The manager can set up the game apparatuses in the penny arcade without cost or at very low cost instead of risking the possibility of purchasing the game apparatuses (software), and the manager pays a fixed royalty to the manufacturer from the sales.
Such a business model makes it possible to share the risk and profit speedily and appropriately between the developer of the game apparatus and the manager of the penny arcade as supplying new titles of games in response to the change in taste, which the fickle arcadians have. Then, this will be mainstream from now on in connection with the business model of the penny arcade.
In this business model, it is very important to correctly grasp the actual working state of the game apparatus periodically. Namely, the royalty is collected based on information about how many times the game is played and how many coins are put in the apparatus, and the operation of the game must be stopped when the period of a contract expires.
By the way, since the penny arcades are provided in amusement areas, and sightseeing spots all over the country, the technician must be on a business trip periodically to check the working state of the game apparatus, stop the apparatus whose period of contract has expired, and restart the game apparatus whose period of contract has been renewed, so that extremely much management cost is required.
The penny arcades in many places and the management center of the manufacturer are connected to each other over the network (Internet), a public telephone line and the like, making it possible to mange the game apparatuses at remote sites. However, there is difficulty in adopting such a method of remote control across the board since the facility environment for the penny arcades vary and there is a cost bearing problem.
There can be considered the method in which the management of operating the game apparatuses is left to the penny arcade and billing process is carried out based on the sales report from the penny arcade. This method, however, has a problem in which the actual state of the penny arcade and the truth of the sales report cannot be easily confirmed.

These objects and other objects and advantages of the present invention will become more apparent upon reading of the following detailed description and the accompanying drawings in which:
An embodiment of the present invention will be specifically described with reference to the drawings accompanying herewith.
As illustrated in
As illustrated in
The main controller 11 and the aforementioned processing and managing modules are implemented when a CPU, which is built in the game apparatus 10, reads a given control program recorded on a control program recording area (not shown) appropriately and executes it. This program may be one that is recorded on a transportable recording medium such as a CD-ROM, and the like. Also, this program may be one that forms the above modules and various kinds of DBs in cooperation with an operating system, which is built in the game apparatus 10 and which is mounted on a computer main body, and/or a BIOS (Basic Input Output System).
The password analyzing processor 12 has a function of analyzing an encrypted game apparatus license data (license password) inputted from the keyboard to return such encrypted data to license data of a plaintext (non-encrypted data). On the other hand, the password generation processor 15 has a function of encrypting working state data of the interior of the game apparatus 10 to generate encrypted working state data (management password). The generated management password is outputted from the aforementioned display device or printer via the input/output controller 19.
Regarding the encrypting and decoding technique used in the password analyzing processor 12 and the password generation processor 15, the encryption technique, which is generally known, for example, DES (Data Encryption Standard) and the like, is used. However, they are not limited to the specific encryption technique and any encryption technique may be possible if it is a technique that makes it difficult to decode the encrypted password in a rational effort range.
The timer 16 is a calendar and timer capable of setting year, month, day, and time from the outer unit. Normally, the manager of the penny arcade sets the date and time at the time of setting up the apparatus, thereafter the timer 16 performs the time counting operation automatically and serves as an internal calendar and timer of the game apparatus 10. The RTC 17 is a timer that performs the time counting operation in accordance with date and time information, which is set based on Greenwich Mean Time at a manufacturing time. The RTC 17 has a unique power source. The use of these timers will be more specifically described later.
The data storage 18 is a storing section for storing a game program executed by the game apparatus and various kinds of data necessary for operating the apparatus.
The password generating processor 42 has a function of encrypting ID of the licensing game apparatus inputted from the keyboard and the license condition to generate license data (hereinafter referred to as license password) of the encrypted game apparatus. The password analyzing processor 43 analyzes working state data (hereinafter referred to as management password) of the game apparatus inputted from the keyboard and encrypted to return such encrypted data to management state data of a plaintext (non-encrypted data). The analyzed management password is outputted from the aforementioned display device or printer via the input/output controller 45.
The encryption technique used in the password generating processor 42 must be the same as the encryption technique used in the password analyzing processor 12 of the game apparatus 10. Also, the encryption technique used in the password analyzing processor 43 must be the same as the encryption technique used in the password generating processor 15 of the game apparatus 15. Namely, it is required that the password analyzing processor 12 of the game apparatus 10 should correctly analyze the license password generated by the password generating processor 42 of the managing apparatus 40. Moreover, it is required that the password analyzing processor 43 of the managing apparatus 40 should correctly analyze the management password generated by the password generating processor 15 of the game apparatus 10. It is possible to use the encryption technique common to these password generating and analyzing processors 12, 15, 42, and 43.
The main controller 11 and the aforementioned processing (modules) are implemented when a CPU, which a computer main body built in the managing apparatus 10 has, reads a given program recorded on a program storing area (not shown) appropriately and executes it. This program may be one that is recorded on a transportable recording medium such as a CD-ROM, and the like. Also, this program may be one that forms the above modules and various kinds of DBs in cooperation with an operating system, which is mounted on the computer main body built in the managing apparatus 40, and/or a BIOS (Basic Input Output System).
Sequentially, an explanation will be given of the management of the game apparatus using the game apparatus management system according to this embodiment.
First, an initial setting of the game apparatus 10 will be explained with reference to
It is assumed that the penny arcade newly sets up the game apparatus 10 based on the license contract. When the game apparatus 10 is started (Step 101, hereinafter simply referred to as S), the software execution controller 13 of the main controller 11 reads a start-up control program (not shown) from the management data storage 32 of the data storage 18 and requests the inputs of date sear, month, day) and current time (S102). When the manager of the rental destination enters these inputs, the software execution controller 13 compares information of inputted date and time with date and time outputted from the RTC 17 (S103), and determines whether or not such information is included within a given time difference range (S104). The location where the game apparatus 40 is not limited to Japan, and a predetermined time difference is set to be allowable within an appropriate range as considering the case in the apparatus is set up at the foreign location. In the case where the inputted date and time are within the range of the predetermined time difference (S104: YES), the software execution controller 13 sets the inputted date and time to the timer 16 (S105). In the case where the inputted date and time are not within the range of the predetermined time difference (S104: NO), the software execution controller 13 determines it as an error, and requests the re-input until the suitable date and time are inputted (S102). Thus, comparison between the so-called reference date and time data supplied from the RTC 17 and date and time data to be inputted is performed, and input data, which largely deviates, is not set to the timer 16. This makes it possible to prevent unauthorized operation of date and time data. Even if time set to the timer 16 is lost for some reasons, the current date and time is reset according to the same procedure.
An explanation will be next given of the license management of the game apparatus using this management system.
Back to
An explanation will be next given of the input of the password and the following operation with reference to
Sequentially, the software execution controller 13 extracts the game apparatus ID data from the analytical result, and compares the extracted game apparatus ID with ID of the game apparatus 10 prestored in the apparatus ID storage 30 to determine whether they match each other or not (S203). When they do not match each other (S203: NO), the software execution controller 13 displays that the license password is incorrect on the display device (S211), and waits until a new password is inputted (S201). When they match each other (S203: YES), the software execution controller 13 extracts license period data from the analytical result and determines whether or not current date data outputted from the timer 16 is between the license start time and the license end time (S204).
In the case where the determination result is affirmative (S204: YES), the software execution controller 13 displays the analyzed license period on the display device, and confirms whether or not the displayed period is correct (S205).
In the case where the confirmation by the licensee can be obtained (S205: OK), the software execution controller 13 permits the execution of the game program, and the main controller 11 starts the execution of the game program stored in the game program storage 31 (S206).
This makes it possible for the licensee to start the business operation of the game apparatus 10 (S207). After starting the business operation, the working state managing unit 14 of the game apparatus 10 records data of at least the sales (the cumulative number of coins received by the coin storing apparatus) and data of the number of playing times into the working state storage 34 of the data storage 18.
In the case where the determination result is negative (S204: NO), the software execution controller 13 prohibits the main controller 11 from executing the game program stored in the game program storage 31 (S208), and requests the input of the license password again until a suitable license password is inputted (S201). Accordingly, the license cannot start the business operation of the game apparatus 10.
Thereafter, the software execution controller 13 of the game apparatus 10, which has started to execute the game program, determines whether or not current date and time data is between the license start time and the license end time (S209) periodically (e.g., once a day) to check whether or not the license period is not ended.
In the case where the license period has not ended (S209: NO), the software execution controller 13 permits the main controller 11 to continue the execution of the game program.
In the case where the determination result is positive (S209: YES), the software execution controller 13 instructs the main controller 11 to stop the execution of the game program, so that the main controller stops the execution of the game program (S210). After that, the software execution controller 13 requests the input of the license password again (S201). In this case, the software execution controller 13 may display a message stating that the license period is ended on the screen page of the display device concurrently.
From the above explanation, it is understandable that the business operation of the specific game apparatus can be executed for only a given period using the encrypted license password.
An explanation will be next given of the management of the working state of the game apparatus 10 with reference to
The manufacturer that has received the management password inputs the management password to the managing apparatus 40. When the management password is inputted from the keyboard, the password analyzing processor 43 of the managing apparatus 40 analyzes the inputted management password. The analyzed working state data is outputted in a visible form from the display apparatus or the printer.
Back to
From the above explanation, the manufacturer can grasp the working state of the specific game apparatus and charge the licensee the amount using the encrypted license password transmitted from the penny arcade.
Though the above has explained the present invention based on the specific embodiment, and it is needless to say that the present invention can adopt other embodiment without limiting to the above embodiment.
For example, the above embodiment has explained the case in which the manufacturer sets the license period and permits the game apparatus to be operated for only the license period. However, the other conditions may be possible. For example, the arrival at a predetermined sales after starting the operation of the game apparatus may be set as a license ending condition, and the arrival at predetermined number of times the game is played may be set as a license ending condition. In this case, instead of license period data, data indicative of a licensing method (period, the number of playing times or sales) and the content of a license (data indicative of the limit of period, the upper limit number of times the game is played or sales) may be encrypted and put in the license password generated by the managing apparatus 40.
For example, in the case where a license password is generated based on the conditions that the game ID is 123, the license method is 2, and the license condition is 1500 (times), x (=12321500) is calculated using the following equation:
x=(game apparatus ID×100000)+(license method×10000)+(license content)
The calculated x is substituted into the known encryption function f(x) to obtain license password y=f(x).
If the license password y is substituted into a code function g(y), which is an inverse function of the above encryption function, an original code sequence x (=12321500) is uniquely obtained. From the obtained x, a license condition can be given:
Game apparatus ID=x÷100000
License method=(x−game apparatus ID×100000)÷10000
License content=(x−game apparatus ID×100000−(license method×1000))
Each data of the given game apparatus ID, license method, and license content is stored in the license condition storage 33 (S301).
The software execution controller 13 extracts the game apparatus ID data from the analytical result, and compares the extracted game apparatus ID with ID of the game apparatus 10 prestored in the apparatus ID storage 30 to determine whether they match each other or not (S302). When they do not match each other (S303: NO), the software execution controller 13 displays that the license password is incorrect on the display device (S304), and waits until a new password is inputted (S201). When they match each other (S302: YES), the software execution controller 13 extracts data of the license method from the analytical result, and specifies the kind of data (S303). In the case where the license method is 1 (period), the operations afterward are the same as those of the aforementioned embodiment, and processing is back to S204 of
In the case where the license method is the number other than 1 (namely, the number of playing times or sales) (S305: NO), the software execution controller 13 permits the execution of the game program, and the main controller 11 starts the execution of the game program stored in the game program storage 31 (S306). In the case where the license condition is not the period, comparison and determination relating to the date and time are not performed.
Thereafter, the software execution controller 13 of the game apparatus 10, which has started to execute the game program, checks data stored in the working state storage 34 periodically (e.g., after the end of one game) to determine whether or not the current number of playing times or sales is within the range of the limitation (S307).
In the case where the determination result is affirmative (S307 YES), the software execution controller 13 permits the main controller 11 to continue the execution of the game program. In the case where the determination result is negative (S307: NO), the software execution controller 13 prohibits the main controller 11 from executing the game program (S308), and waits until a new password is inputted (S201).
The above embodiment has explained the case in which the game apparatus 10 is suddenly stopped when the license period expires or the number of playing times or sales exceeds the limitation. However, the following method may be executed.
Namely, it is calculated how many days are left before the license period is ended or how many sales or playing times are left before they reach the limitation. Then, when the remainder of the license period becomes less than predetermined days (e.g., one month) or the remainder of the sales or playing times becomes less than a predetermined value (e.g., 100 Yen or 10 playing times), a screen page urging the manager of the penny arcade to renew the license contract may be displayed on the display device.
From the above explanation, it is understandable that there is disclosed the technique for managing the game apparatuses remotely without providing any special facilities to the penny arcade. According to the present invention, it is possible to start and stop an operation of the game apparatus based on a given contract condition and to transmit the working state during that time accurately to the manufacturer without using a data communication line and the like.
Various embodiments and changes may be made thereunto without departing from the broad spirit and scope of the invention. The above-described embodiment intended to illustrate the present invention, not to limit the scope of the present invention. The scope of the present invention is shown by the attached claims rather than the embodiment. Various modifications made within the meaning of an equivalent of the claims of the invention and within the claims are to be regarded to be in the scope of the present invention.
