DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0025]
(First embodiment)
FIG. 1 is a schematic diagram showing a configuration of an IC card system for a game machine according to a first embodiment of the present invention, and FIG. 2 is a schematic diagram showing a file configuration of an IC card applied to the IC card system for a game machine. FIG.
[0026]
The IC card system for game machines of this embodiment is an IC card applied to a game machine at an amusement (AM) facility such as a game center.
[0027]
Specifically, the IC card system for a game machine includes a plurality of stores A to N of an AM facility, and an overall counting device TC connected to these stores A to N. Since each store A to store N has the same configuration except for the number and arrangement of devices and game content, the configuration of store A will be described here as an example.
[0028]
The store A includes a game card data input device 10, a game machine 20 with R / W (reader / writer), an adding device 30, and a data totaling device 40. In addition, although the game card data input device 10, the game machine 20 with R / W, and the addition device 30 are not shown in figure, each arbitrary number is provided.
[0029]
The game card data input device 10 has a game token input function for inputting a game token (game execution right) into the electronic wallet of the IC card 50 shown in FIG. 2 and issuing the IC card 50 based on the inserted money. Yes. Note that the game token is used as a substitute for conventional money, and is specifically data indicating the degree of the right to execute the game, and a desired number of times according to the value. Has the function to allow the game to run. For example, a game token is usually a coin (small piece) made of metal or plastic, but in the present invention, it is digital data stored in an IC card, and the value can be increased or decreased by rewriting. Yes.
[0030]
In addition, it is preferable from the viewpoint of ensuring security that the game token is not compatible with the existing system and does not have cashability. In order to ensure the security of game token exchange, the game card data input device 10, the R / W-equipped game machine 20, and the adder device 30 substantially exchange game tokens with the IC card 50. A SAM (Secure Access Module) is installed.
[0031]
The R / W-equipped game machine 20 has a function of substantially reducing the value of the game token in the IC card 50 when the IC card 50 is inserted. Here, “substantially decrease” does not necessarily mean that the value of the digital data corresponding to the game token itself is decreased, and the degree of game execution right is set regardless of the increase or decrease of the value of this digital data. It shows that it is reduced.
[0032]
For example, if the increase / decrease in the level of the game execution right and the value of the digital data are the same, the value of the game token is increased in proportion to the amount of money inserted (0 → +), and the game is executed every time the game is executed. The token value is decreased (0 ← +).
[0033]
On the other hand, if the increase / decrease in the degree of the game execution right and the value of the digital data are reversed, the value of the game token is decreased in proportion to the amount of money inserted (− ← 0), and each time the game is executed The value of the game token is increased (− → 0).
[0034]
In any case, it goes without saying that the degree of game execution right and the amount of money inserted are proportional to each other. In other words, the game token has a property that it is substantially reduced every time the game is executed and increased in proportion to the amount of money inserted.
[0035]
Further, the R / W game machine 20 has a function of permitting game execution according to the value of the game token recorded in the IC card 50.
[0036]
In this embodiment, the case where the value of the game token in the IC card 50 is decreased every time the game is executed will be described as an example. As described above, the value of the game token is changed every time the game is executed. Even if it is increased, the operation is substantially the same.
[0037]
Further, the R / W-equipped game machine 20 is designed so that only the process of decreasing the value of the game token can be executed from the viewpoint of security against theft and the like, and the process of increasing the game token cannot be executed.
[0038]
The adding device 30 has a game token increasing function for substantially increasing the value of the game token in the IC card 50 based on the inserted money when the IC card 50 is inserted.
[0039]
A data totaling device (host computer) 40 is provided at each store to which the game machine with R / W 20 belongs, and the value of the game token input by the game card data input device 10 is reduced by the game machine 20 with R / W. The game token value and the game token value increased by the adder 30 are added to each IC card 50.
[0040]
The IC card 50 has an externally readable / writable memory, and in this memory, as shown in FIG. 2, an MF (Master File), PIN (Personal Identification Number), card ID, user information ( Gender, date of birth), DF (Dedicated File (electronic wallet (game token (can set the limit)))), security, URL (for all users), DF (game data, game results, URL (good results) It is configured to hold a file such as a user))), and a user ID assigned and managed independently of the card ID in the memory is printed or embossed on the surface of the IC card 50. Note that the user information is not limited to the date of birth, but age-related data such as age or age group, or a combination of one of them and a birthday can be used.
[0041]
On the other hand, the total tabulation device (total host computer) TC tabulates the tabulation results of the data tabulation devices 40 to 40N in all stores A to N.
[0042]
Next, the operation of the game machine IC card system as described above will be described.
Now, in the store A, it is assumed that money as bills or coins is inserted into the game card data input device 10 by the user. The game card input device 10 inputs a game token to the IC card 50 based on the amount of money inserted, inputs user information obtained by a user operation to the IC card 50, and issues the IC card 50. . Note that either the game token or the user information may be input first.
[0043]
The issued ID card 50 is inserted into a desired game machine 20 with R / W by the user. When the IC card 50 is inserted, the R / W-equipped game machine 20 reads out user information from the inserted IC card 50 and subtracts a game token having a value corresponding to one game fee. Allow execution.
[0044]
The IC card 50 holds a new balance reflecting the subtraction result. Thereby, a user plays the game of the game machine 20 with R / W.
[0045]
Upon completion of the game, the R / W-equipped game machine 20 cancels the game execution permission to disable the user operation and permits the IC card 50 to be discharged. Note that the game token in the IC card 50 may be newly subtracted by an operation corresponding to a continuation command, for example, before the game ends, while the game may be continued from the current state.
[0046]
Since the R / W-equipped game machine 20 can only reduce the game tokens, the game tokens in the IC card 50 cannot be increased even in the case of theft, so that excellent security against theft can be realized.
[0047]
Next, when the game token in the IC card 50 becomes small or zero as the game is executed, the user inserts the IC card 50 into the adding device 30 and inserts money as desired. .
[0048]
When the IC card 50 is inserted, the adding device 30 increases the game token in the IC card 50 based on the inserted money. Thereby, the IC card 50 can execute the game again on the R / W-equipped game machine 20.
[0049]
On the other hand, in such a store A, for example, the game card data input device 10, the R / W-equipped game machine 20, and the adding device 30 are requested by the user from the data totaling device 40 every predetermined time. The information and the updated (increased or decreased) game token information are paired and sent to the data counting device 40. Thereby, the data totaling device 40 can grasp the user and the game token (sales).
[0050]
Further, for example, when the game is finished with good results (high score), the game machine with R / W 20 sends the game result together with the user information of the IC card 50 to the data totaling device 40 by an operation corresponding to the totaling command. . Thereby, the data totaling device 40 can grasp the user with a good result (high score) and the game result thereof.
[0051]
In addition, the data totaling device 40 sends a set of user information and sales, or a set of user information and game results to the total counting device TC. The above operation is common to the stores A to N. Accordingly, the total counting device TC receives and counts the totaling results of the data totaling devices 40 to 40N in all the stores A to N, so that the user trends, sales and game results in all the stores A to N are obtained. Can be managed.
[0052]
As described above, according to the present embodiment, in each store A, the data totaling device 40 can grasp the sales amount of each R / W game machine 20 for each time zone, and each R / W for each time zone. Based on the user information in the game machine 20 with W, user information such as the user's age and sex in each R / W game machine 20 for each time zone can be grasped.
[0053]
In addition, these aggregated data can be used to set promotional prices flexibly, such as (1) timed promotional prices based on gender and age, (2) personalized services such as birthday promotional prices, etc. Or (3) by executing various plans such as providing a game results ranking announcement service in the store, it is possible to encourage further use of the game machine.
[0054]
On the other hand, in the entire store, the total counting device TC can manage user trends, sales, and game results in all stores A to N. As a result, for example, (1) basic marketing for planning and launching a new game can be easily realized, and (2) rankings of game results are tabulated and ranking information for all stores is stored in each store A to N. Can be used to arouse the use of the game machine, and (3) similarly, the ranking can be announced on the Internet homepage to arouse the use of the game machine.

This application example shows a form of mail-order sales in which goods can be purchased from the consumer game machine 60 with R / W in the home via the Internet.
[0079]
That is, the consumer game machine 60 with R / W selects an item to be purchased from the homepage by the user's operation. The host computer 80 of the home page identifies the user based on the card ID of the IC card 50 and issues a reception number, notifies the user of the reception number, and sets the combination of the card ID and the reception number to the total counting device TC. To give. The total tabulation device TC stores and maintains a set of a card ID and a reception number for a certain period until a payment notice is sent from a settlement organization 90 having a POS (Point 0f Sale) system such as a convenience store.
[0080]
Thereafter, the user carries the IC card 50 and goes to the settlement institution 90, and gives the receipt number to the store clerk.
[0081]
In the settlement institution 90, a computer with R / W (not shown) reads the card ID of the IC card 50 by the operation of the store clerk and sends the input reception number and card ID to the total counting device TC. The total counting device TC confirms whether or not there is a combination of the stored card ID and receipt number, and transmits it to the R / W-equipped computer of the clearing house 90. Thereafter, the R / W-added computer displays a reply that the application is valid and prints out an invoice for the article via the printer.
[0082]
Hereinafter, when the user obtains the price in the same way as the payment of the public utility bill etc., the bar code of the invoice is read by the R / W-equipped computer, and a notification indicating that the price of the goods has been paid is sent to the total counting device TC. Sent out. The invoice is handed over to the user after the receipt is pressed.
[0083]
Upon receipt of the notice of payment, the total tabulation device TC contacts the article identification information, the user's name and address set, for example, with the article delivery department, and executes a process for delivering the article to the user's home.
[0084]
As described above, according to the present embodiment, since the price is not settled on the Internet and the goods are delivered after the price is received, mail order on the Internet can be operated extremely safely.
[0085]
In addition, when the URL differs according to the game result, the sales amount of the article can be estimated for each homepage based on the number of URLs issued.
[0086]
(Fourth embodiment)
Next, an IC card system for a game machine according to a fourth embodiment of the present invention will be described with reference to FIG.
[0087]
In other words, the present embodiment is a modification of the first embodiment and is intended to improve security. Specifically, both the IC card 50 and the game machine 20 with R / W are connected to each other. It has a mutual authentication security function to confirm each other.
[0088]
Here, in addition to the functions described above, the IC card 50 is stored in the card ID for calculating authentication data based on the diversified encryption key or in the IC card 50 itself according to the request of the game machine 20 with R / W. A function for sending authentication data calculated using its own diversified encryption key or a game token value to the game machine 20 with R / W, and a game with R / W received from the game machine 20 with R / W Security in which the machine 20 calculates a diversified encryption key based on the card ID of the IC card 50 and confirms the payment request for the authentication data or the game token calculated using the key, and executes countermeasures such as communication disconnection when it is illegal It has a function.
[0089]
In addition to the configuration described above, the R / W-equipped game machine 20 confirms the authentication data transmitted from the IC card 50, the card ID, and the game token value, respectively. It has a security function to execute the countermeasure process.
[0090]
Further, the game machine 20 with R / W is different from the first embodiment from the viewpoint of speeding up the processing, and each game (new execution, re-execution, or continuation) in the game machine 20 of the self-game machine 20 is performed. The game token is not subtracted, and the game token in the IC card 50 is substantially subtracted only once at the end of the entire game where the user leaves the game machine 20 of the user.
[0091]
However, the game machine with R / W 20 can execute the above-described security function even when the game token is substantially subtracted for each game, as in the first embodiment. Conversely, it goes without saying that the function of substantially subtracting the game token only once at the end of the entire game may be applied to the R / W-equipped game machine 20 of the first embodiment.
[0092]
Next, the operation of the game machine IC card system as described above will be described. In addition, the overlapping description is abbreviate | omitted and the part relevant to the security function between IC card 50 and the game machine 20 with R / W is described here.
First, when the IC card 50 is inserted into the R / W of the R / W-equipped game machine 20, the R / W-equipped game machine 20 is based on the ID information with the IC card 50 as shown in FIG. So-called dynamic authentication is performed with involuntary elements such as random numbers using a diversified encryption key.
[0093]
For this, a card ID that the IC card 50 has uniquely is used. Further, the R / W-equipped game machine 20 stores a key (so-called master key) that is a source for calculating a diversified encryption key from the ID information.
[0094]
The IC card 50 has a diversified encryption key calculated and stored using a master key at the time of initialization.
[0095]
Dynamic authentication is performed as follows.
That is, the IC card 50 stores therein the authentication data calculated and transmitted by the R / W game machine 20 using the authentication data verification diversified encryption key calculated based on the card ID of the IC card 50. By verifying with the authentication data verification diversified encryption key, it is determined whether or not the R / W-equipped game machine 20 is an officially manufactured machine (forged machine). The processing is immediately terminated due to disconnection of communication, etc., but when the machine is officially manufactured, the authentication data calculated using the diversified encryption key for authentication data calculation stored in the IC card 50 itself is attached with R / W. In order to make the game machine 20 verify, it will respond to reading of necessary information.
[0096]
Next, the R / W-equipped game machine 20 calculates a diversified encryption key for calculating authentication data based on the card ID of the IC card 50, and verifies the authentication data transmitted from the IC card 50. It is determined whether or not the IC card 50 is officially issued (forged IC card). When the IC card 50 is a forged IC card, the processing is terminated by disconnecting the communication, etc., and the counterfeit IC card is used by an administrator or the like. Inform you that
[0097]
In the above-described so-called dynamic mutual authentication process, authentication data verification from the R / W-equipped game machine 20 by the IC card 50 and authentication data verification from the IC card 50 by the R / W-added game machine 20 are performed. The order of the two processes may be changed.
[0098]
In the above example, the symmetric encryption key method (so-called common encryption key method) is used for explanation, but the verification flow is the same in the case of the asymmetric encryption method (so-called public encryption key method).
[0099]
Note that the above-described dynamic authentication may be performed during the process of subtracting and adding game tokens held by the IC card 50 and the R / W game machine 20.
The dynamic authentication can also be performed between the IC card 50 and the adding device 30.
[0100]
Further, the R / W-equipped game machine 20 requests the IC card 50 to transmit the value of the game token when the determination result indicates an officially issued IC card.
[0101]
Thereby, the IC card 50 transmits the value of the currently remaining game token to the game machine 20 with R / W.
[0102]
Next, the R / W-equipped game machine 20 determines the magnitude relationship between the value of the game token received from the IC card 50 and the value of the game token required to execute its own game, and the game received from the IC card 50 When the token value is less than the game token value required for game execution, the user is notified that the game cannot be executed, and the IC card 50 is ejected from the R / W.
[0103]
Further, the R / W-equipped game machine 20 executes its own game when the value of the game token received from the IC card 50 is equal to or greater than the value of the game token required for game execution. As a result, the user plays the game in the same manner as described above, and when the game ends, inputs a command as desired, and re-executes (replays) or continues the game.
[0104]
The R / W-equipped game machine 20 subtracts the value of the game token required for game execution from the value received from the IC card 50 at the end of the game, for example, and subtracts the value of the game token when the game is re-executed or continued. And the magnitude relation between the value of the game token required for game execution. Here, when the value of the subtracted game token is less than the value of the game token required for game execution, the re-execution or continuation of the game is stopped and the process of the game function is forcibly terminated.
[0105]
Subsequently, when the game function is forcibly ended or the game is arbitrarily ended in this way, the R / W-equipped game machine 20 issues a payment request to pay the value obtained by integrating the subtraction result of the game token to the IC card. Give to 50.
[0106]
The IC card 50 determines whether or not the value of the game token received from the R / W game machine 20 is valid, and the determination result is incorrect (the payment request value does not indicate the characteristics of the game token). If the determination result is valid, the game token in the memory is reduced by the amount required for payment, and the fact that the game token has been reduced is R /. Notify game machine 20 with W.
[0107]
Next, the R / W-equipped game machine 20 determines whether or not the notification from the IC card 50 is valid, and ends the process when the determination result is incorrect, but when the determination result is valid, The ID and the value of the reduced game token (and the user information described above) are transmitted to the data totaling device 40.
[0108]
After the transmission is completed, the R / W-equipped game machine 20 ends the process and ejects the IC card 50 from the R / W.
[0109]
As described above, according to the present embodiment, in addition to the effects of the first embodiment, the security system always operates between the IC card 50 and the R / W game machine 20 for each device. Since the security function is realized without providing the security device, the security can be improved and the security processing capability and processing speed can be improved.
[0110]
Specifically, in the first embodiment, the security system always operates between the IC card 50 and the adding device 30 for each device. Since the security system is added, the security can be further improved.
[0111]
In addition, the above-described security function is partly or entirely stored in the SAM (mounted in the game machine 20 with R / W and the adder 30) and assigned to it, thereby concealing information and calculation processes. High security can be realized.
[0112]
In the first and fourth embodiments, the case where the value of the digital data of the game token is decreased corresponding to the number of times of game execution has been described for convenience of understanding. Even if the configuration is such that the value of the digital data of the game token is increased, as described above, since the game token is substantially decreased, the present invention can be similarly implemented to obtain the same effect.
[0113]
In addition, the present invention can be implemented with various modifications without departing from the gist thereof.
[0114]
【The invention's effect】
As described above, according to the present invention, it is possible to provide an IC card system for a game machine that can execute a game without carrying money.
