Embodiments of the present invention will be described below with reference to the drawings.

(First Embodiment) FIG. 1 is a schematic diagram showing a configuration of a game machine IC card system according to a first embodiment of the present invention, and FIG. 2 is applied to this game machine IC card system. FIG. 2 is a schematic diagram showing a file configuration of an IC card to be executed.

The IC card system for a game machine according to the present embodiment is one in which an IC card is applied to a game machine at an amusement (AM) facility such as a game center.

Specifically, the game machine IC card system includes a plurality of stores A to N in an AM facility and a total counting device TC connected to the stores A to N. The stores A to N have the same configuration except for the number and arrangement of the devices and the content of the game. Therefore, the configuration of the store A will be described here as an example.

Store A is a game card data input device 1
0, a game machine 20 with R / W (reader / writer), an adding device 30, and a data totaling device 40. Note that the game card data input device 10, the R / W-equipped game machine 20
Although not shown, the adder 30 is provided with an arbitrary number.

The game card data input device 10 inputs a game token (game execution right) to the electronic wallet of the IC card 50 shown in FIG. 2 based on the inserted money.
It has a game token input function for issuing the IC card 50. It should be noted that the game token is used as a substitute for conventional money, and specifically, is data indicating the degree of the right to execute a game,
It has a function of permitting execution of a desired game by the number of times corresponding to the value. 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. I have.

It is preferable that the game token is incompatible with the existing system and has no cash value from the viewpoint of ensuring security. In order to secure the security of the exchange of game tokens, the game card data input device 10, the R / W-equipped game machine 20, and the adding device 30 substantially exchange game tokens with the IC card 50. SAM (Secure
Access Module) is installed.

The R / W-equipped game machine 20 includes an IC card 50
Has a function of substantially reducing the value of the game token in the IC card 50 when is inserted. here,
"Substantially decrease" is not necessarily to reduce the value of the digital data corresponding to the game token, and regardless of the increase or decrease of the value of the digital data,
This indicates that the degree of the game execution right is reduced.

For example, when the degree of the game execution right and the increase / decrease of the value of the digital data are set to be the same, the value of the game token is increased in proportion to the amount of the inserted money (0 →
+), The value of the game token is reduced every time the game is executed (0 ← +).

On the other hand, when the degree of the game execution right and the increase / decrease of the value of the digital data are set to be opposite, the value of the game token is reduced in proportion to the amount of the inserted money (-← 0),
Each time the game is executed, the value of the game token is increased (−
→ 0).

Regardless of the setting, it goes without saying that the degree of the game execution right and the amount of money inserted are proportional to each other. That is, the game token has a property that it is substantially reduced every time the game is executed, and is increased in proportion to the amount of the inserted money.

The R / W game machine 20 has a function of permitting the execution of the game according to the value of the game token recorded on the IC card 50.

In the present embodiment, the case where the value of the game token in the IC card 50 is reduced every time the game is executed will be described as an example. Even if the value of is increased, the operation is substantially the same.

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 and the process of increasing the game token cannot be executed from the viewpoint of security against theft and the like.

When the IC card 50 is inserted, the adding device 30 operates based on the inserted money.
It has a game token increase function that substantially increases the value of the game token in the game token.

Data aggregation device (host computer) 4
0 is provided for each store to which the R / W-equipped game machine 20 belongs, and the value of the game token input by the game card data input device 10, the value of the game token reduced by the R / W-equipped game machine 20, and It has a function of totalizing the value of the game token increased by the adding device 30 for each IC card 50.

The IC card 50 has an externally readable / writable memory. In this memory, as shown in FIG. 2, an MF (Master File) and a PIN (Personal Identif.)
communication Number), card ID, user information (sex, date of birth), DF (DedicatedFile (electronic wallet (game token (limit can be set)))), security, U
RL (for all users), DF (for game data, game results, URL (for high-performance users)), and other files. The IC card 50 has a card ID in the memory on its surface. A user ID that is assigned and managed independently from the user ID is printed or embossed. Note that the user information is not limited to the date of birth, but may be an age, an age group, or a combination of one of them and a birthday.
Age-related data corresponding to the age can be used.

On the other hand, the total counting device (entire host computer) TC counts the counting results of the data counting devices 40 to 40N in all the stores A to N.

Next, the operation of the above-described game machine IC card system will be described. Now, at store A,
It is assumed that money as bills or coins is inserted into the game card data input device 10 by a user. The game card input device 10 inputs a game token to the IC card 50 based on the amount of money inserted, and inputs user information obtained by a user operation to the IC card 50.
And issues the IC card 50. Any of the game token and the user information may be input first.

The issued ID card 50 is inserted into the desired R / W-equipped game machine 20 by the user. R / W

The user information to be updated and information on the updated (increased or decreased) game token are sent to the data totaling device 40 as a set. Thus, the data totaling device 40 can grasp the user and the game token (sales amount).

Also, for example, when the game ends with a good result (high score), the R / W
The attached game machine 20 sends the game result to the data totaling device 40 together with the user information of the IC card 50. Thereby, the data totaling device 40 can grasp the user who has a good result (high score) and the game result.

The data totaling device 40 sends a set of user information and sales amount, or a set of user information and game result to the overall totaling device TC. The above operation is common to each of the stores A to N. Therefore, the total counting device TC
Then, the data totaling device 4 in all the stores A to N
By receiving and totaling the totaling results of 0 to 40N,
In all stores A to N, user trends, sales, and game scores can be managed.

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-equipped game machine 20 for each time period, and Based on the user information in each R / W-equipped game machine 20, user information such as the age and gender of the user in each R / W-equipped game machine 20 in each time zone can be grasped.

Using these aggregated data, the promotion price can be flexibly adjusted, for example, (1) a time-limited promotion price can be set according to gender and age, and (2) a personalized service such as a birthday promotion price. , And (3) executing a variety of projects such as a game performance ranking announcement service in a store, to further encourage the use of the game machine.

On the other hand, in the store as a whole, the total counting device TC can manage user trends, sales and game results in all stores A to N. This allows
For example, (1) basic marketing for planning and launching a new game can be easily realized, (2) ranking of game results is totaled, and stores A to N are made to announce ranking information for all stores. (3) Similarly, the ranking can be announced on the home page of the Internet to encourage the use of the game machine.

The part related to the security function between and will be described. First, the IC card 50 is set to the R / W
/ W, the R / W-equipped game machine 20 causes an involuntary element such as a random number to be interposed between the IC card 50 and the IC card 50 using a diversified encryption key based on ID information, as shown in FIG. Also, so-called dynamic authentication is performed.

For this purpose, a card ID which the IC card 50 has uniquely is used. The R / W-equipped game machine 20 stores a key (so-called master key) serving as a source for calculating a diversified encryption key from the ID information.

At the time of initialization of the IC card 50, a diversified encryption key is calculated using a master key and stored.

The dynamic authentication is performed as follows. That is, the IC card 50 is a game machine 20 with an R / W.
The authentication data calculated and transmitted using the authentication data verification diversifying encryption key calculated based on the card ID of the card 50 is verified by the authentication data verification diversification encryption key stored therein, thereby achieving R / It is determined whether or not the W-attached game machine 20 is an officially manufactured machine (a forged machine). If the machine is a forged machine, the processing is immediately terminated by disconnecting the communication. IC
The authentication data calculated using the authentication data calculation diversified encryption key stored in the card 50 itself is transferred to the R / W-equipped game machine 2.
In order to verify to 0, it is necessary to read necessary information.

Next, the R / W-equipped game machine 20 calculates a diversifying 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. Thus, it is determined whether or not the IC card 50 has been officially issued (a forged IC card). If the forged IC card is a forged IC card, the processing is terminated by cutting off the communication and the like. Notifies that the card has been used.

In the above-described processing of so-called dynamic mutual authentication, authentication data verification from the R / W-equipped game machine 20 by the IC card 50 and IC data verification by the R / W-equipped game machine 20 are performed.
The order of the two processes of verifying the authentication data from the card 50 may be interchanged.

In the above example, the description has been made using the symmetric encryption key system (so-called common encryption key system). However, the verification flow is the same for the asymmetric encryption system (so-called public encryption key system).

The above-mentioned dynamic authentication may be performed at the time of the processing of subtracting and adding the game tokens possessed by the IC card 50 and the R / W-equipped game machine 20. Further, the above-described dynamic authentication can be performed between the IC card 50 and the adding device 30.

When the determination result indicates an officially issued IC card, the R / W-equipped game machine 20 requests the IC card 50 to transmit the value of the game token.

As a result, the IC card 50 transmits the value of the currently remaining game token to the R / W-equipped game machine 20.

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. When the value of the received game token is less than the value of the game token required to execute the game, the user is notified that the game cannot be executed, and R / W
Is ejected from the IC card 50.

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 to execute the game, the R / W-equipped game machine 20 executes its own game. Accordingly, the user plays the game as described above, and when the game is over, inputs a command as desired, and re-executes (replays) or continues (continues)
ue).

The R / W-equipped game machine 20 subtracts the value of the game token required to execute the game from the value received from the IC card 50 at the end of the game, for example, when the game is re-executed or continued. The value of the token,
A magnitude relationship with a game token value required for game execution is determined. Here, when the value of the subtracted game token becomes less than the value of the game token required for executing the game, the re-execution or continuation of the game is stopped, and the process of the game function is forcibly terminated.

Subsequently, when the game function is forcibly terminated or the game is arbitrarily terminated, the R / W-equipped game machine 20 issues a payment request to pay a value obtained by integrating the result of subtracting the game token. Is given to the IC card 50.

The IC card 50 is used for the R / W-equipped game machine 20.
It is determined whether or not the value of the game token received from the payment request is valid. If the determination result is incorrect (the value of the payment request does not indicate the characteristics of the game token or is larger than the value in the memory, etc.) When the result of the determination is valid, the game token in the memory is reduced by the amount of the payment request, and the R / W-equipped game machine 20 is notified that the game token has been reduced.

Next, the R / W-equipped game machine 20 determines whether or not the notification from the IC card 50 is valid, and terminates the process if the result of the determination is incorrect, but the determination result is valid. At times, the card ID and the value of the reduced game token (and the user information described above) are transmitted to the data totaling device 40.

After the transmission is completed, the R / W-equipped game machine 20 terminates the processing and ejects the IC card 50 from the R / W.

As described above, according to the present embodiment, the first
In addition to the effects of the embodiment, since the security system always operates for each device between the IC card 50 and the R / W-equipped game machine 20, the security function is realized without providing a dedicated security device. In addition, security performance can be improved, and security processing capability and processing speed can be improved.

More specifically, in the first embodiment, the security system always operates for each device between the IC card 50 and the adding device 30. However, the IC card 50 and the game machine with R / W Since a security system between 20 and 20 is added, the security can be further improved.

The above-mentioned security function is partially or wholly stored in the above-mentioned SAM (mounted on the R / W-equipped game machine 20 and the adder 30), thereby providing information and calculation processes. High security can be realized by concealing the information.

In the first and fourth embodiments,
For convenience of understanding, the case where the value of the digital data of the game token is reduced according to the number of game executions has been described. However, the configuration is not limited to this, and the value of the digital data of the game token is increased according to the number of game executions. However, since the number of game tokens is substantially reduced as described above, the present invention can be implemented in the same manner and the same effect can be obtained.

In addition, the present invention can be variously modified and implemented without departing from the gist thereof.
