[0025]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to the drawings. 1 to 6 show a first embodiment of the present invention. The game site operating apparatus according to the present embodiment installs the game site 2 on the Internet, downloads the game program to the terminal 20 of the user who has accessed the game site 2,
It is configured to provide a prize when the result of the game executed at 0 is a win. In addition, the downloaded game program is inspected for tampering.

As shown in FIG. 1, the management of the game site 2 and the management of the contents are generally performed by the management office 1.
A server 10 for operating the game site 2 is installed in the management office 1. Also, server 1
The database 11 connected to 0 is a prize information storage unit 11a that stores various prize information, an advertisement information storage unit 11b that stores various advertisement information, a game storage unit 11c that stores various game programs, and tampering with game programs. It has a user registration unit 11d and the like for registering unauthorized users and the like. Of course, various prize information and advertisement information can be updated at any time.

The game program is created in, for example, the Java (registered trademark) (Java) language developed by Sun Microsystems, Inc.
If you include it in markup language format data,
It can be executed by Java-based search browsing software (browser). Game storage unit 11c of the database 11
The game program stored in is downloaded to the terminal 20 on the user side in response to a request from the search browsing software.

Of course, the game program is Java
The game program may be created in a language other than the language, but the game program according to the present embodiment is downloaded to the terminal 20 at a time together with image data such as a prize list and advertisements, and is executed independently on the terminal 20. It is possible. Further, the game site management program including the game program may be recorded in a magnetically or optically storable portable recording medium such as a CD-ROM, a magneto-optical disk or a floppy (registered trademark) disk.

In the game program, an authentication code for inspecting for tampering is embedded. The authentication code is, for example, an error detection code based on a checksum or CRC (Cyclic Redundancy Check ... Cyclic redundancy check) for the entire game program, or a specific code arranged in the program at address intervals according to a predetermined rule.

The server 10 displays the prize list on the user's terminal 20, and the prize selection acceptance means for accepting the selection of the prize desired by the user from the prize list, and the advertisement related to the advertisement related to the selected prize. It is possible to realize various functions of the related advertisement delivery means that is searched from and displayed on the terminal 20 and the game providing means that enables the terminal 20 to execute the game when the display of the advertisement is completed. In addition, the server 10 serves as a means for receiving a winning report including the address, name, etc. of the winning person by e-mail from the winning person, and a means for transmitting a winning confirmation notification e-mail including the winning number to the winning person. It fulfills the function of.

Further, the server 10 is an inspection means for inspecting whether or not the game program is falsified based on the authentication code included in the winning report and the game program itself, and is a sender of the winning report based on the falsified game program. Registration means for registering a user as an unauthorized user, transmission means for sending an unauthorized report e-mail indicating that tampering has been detected to winners, and prescribed countermeasures against access by registered unauthorized users. It fulfills the function of taking countermeasures.

The terminal 20 receives a communication service using a main body of a computer on the side of a player who uses a game site, a mobile phone, a personal digital assistant, a CATV (cable TV), a WebTV (web TV), a communication satellite or a communication satellite. It includes a television and a game console that can be used. These terminals 20 have predetermined functions such as Internet connection and electronic mail transmission / reception. The game site is built corresponding to the terminal 20 having various functions. It is preferable that the terminal 20 be a mobile phone, in view of the degree of its popularity and convenience.

When connecting to the game site 2 from the terminal 20, it is checked whether or not the user is an unauthorized user. If the user is an unauthorized user, access is denied. If the user is not an unauthorized user, the prize list is displayed on the display section 21 of the terminal 20. And the message "Please select a prize before starting the game" is displayed. The input unit 22 of the terminal 20 is used to select a desired prize from the prize list displayed on the display unit 21. In the present embodiment, the prize to be selected is set to one, but it may be set so that two or more predetermined plurality can be selected.

When the prize has been selected from the prize list,
The advertisement associated with the prize is displayed on the user's terminal, and then the predetermined game program is downloaded to the user's terminal 20. This allows the user to play the game on the terminal 20.

The game that can be executed on the terminal 20 by the game program is, for example, a pattern matching game that is like a slot machine. In the case of a pattern matching game,
After the three symbols are scroll-displayed on the display unit 21 of the terminal 20, the three symbols are stopped and displayed in a predetermined order, and if all three types of the symbols that are stopped and displayed are the same, "winning"
It will be.

In the display unit 21, one game unit starts from the simultaneous start of scroll display of three symbols until all three symbols are stopped and displayed in a predetermined order. In the downloaded game program, when the number of times the game is executed reaches a predetermined upper limit value (for example, 10 times), the game cannot be continuously executed anymore, and the game site 2 must be reconnected and a new download must be made. It is set not to become.

When the result of the game is a win, a win report mail can be sent from the terminal 20 to the server 10. That is, the winning report mail cannot be sent unless the winning is won. The winning report e-mail contains information such as the address, name, and telephone number of the winning person, as well as an authentication code embedded in a predetermined address of the game program or the game program itself.

When the winning report mail is received, the server 10 checks whether or not the game program has been tampered with, based on the authentication code or the sent game program itself. When tampering is detected, a message indicating that the winning is invalid is returned and the user is registered as an unauthorized user. On the other hand, when tampering is not detected, the winning number is issued, and the winning number and the contents of the winning report mail are registered in the database 11 in association with each other as information related to the prize recipient. Further, the server 10 is adapted to send a winning confirmation notification including a winning number to the terminal 20 by e-mail or the like.

When the game is played online without downloading the game program, the terminal 20 is simply used.
The winning number may be displayed on the display unit 21 of.
In such a case, the information regarding the winning numbers and the prize recipients is automatically stored in the database 11 of the server 10 when the result of the game is confirmed as winning.

The computer 30 of the store that can actually provide the prize is connected to the server 10 to store the winning number and the prize providing information stored in the database 11 of the server 10 and the winning number on the user side. The information related to the prize providing destination is collated, and if both match, the prize provided information related to the prize providing is transmitted to the server 10. As a store, a convenience store that is nationwide deployed is preferable from the viewpoint of convenience in providing prizes.

As described above, the server 10 that operates the game site 2, the terminal 20 of the user who uses the game site 2,
The explanation has been centered on the computer 30 in the store where the game is won as a result of the game and the prize is actually provided.
Next, the advertisement displayed with the game, and the server 1
Management of 0 will be briefly described.

As shown in FIG. 1, the advertiser, who is the prize provider, delivers the prize to the store where the prize is actually provided, and places the advertisement at the advertisement agency. Not limited to this, the advertiser does not have to be the same as the prize provider, and may have a certain relationship with respect to the prize provision.

The advertising agency sets up and manages the operation office 1 in which the server 10 is installed, and the operation office 1 requests the advertiser to place advertisements and provide prizes. The actual installation of the server 10 in the management office 1 and the management of the installed server 10 are performed by a business operator such as the system developer of the game site 2.

Next, the game site operating method will be described in more detail. This method is roughly divided into the selection of prizes from the prize list, the display of advertisements, the process of downloading the game program, and the game program based on the authentication code included in the winning report of the game sent from the user. The presence or absence of tampering is checked, and if there is no tampering, a winning number is given, a process of notifying them and a process of collating the winning number in response to an inquiry from the store exchanging the prize are executed. In addition, the game program downloaded to the terminal 20 and the program executed by the computer of the store for exchanging prizes constitute the present system.

FIG. 2 shows the processing performed by the server 10 when the game site is accessed from the user's terminal 20. When the user accesses the game site 2 for the purpose of downloading the game (step S1
01: Y), it is checked whether the user is an unauthorized user (step S102). For example, when the user's terminal is a mobile phone, this check is performed by checking whether the phone number matches the phone number registered in the database 11d as an unauthorized user. In addition, for example, the user ID or the user's e-mail address may be requested to be input, and the database 11d may be searched with these information to check whether the user is an unauthorized user.

As a result of the inspection, if the user is not an unauthorized user (step S103: N), the display unit 21 of the terminal 20 displays
The prize list and the message "Please select a prize before starting the game" are displayed (step S10).
4). At this time, not only the prize list and the message may be displayed, but also a brief description of the game may be displayed together.

The user uses the input unit 22 of the terminal 20 to
Select one prize from the prize list (step S
105: Y), the advertisement corresponding to the selected prize is displayed on the display unit 21 of the terminal 20 (step S106).
When the display of the advertisement ends (step S107:
Y), a predetermined game program is downloaded to the terminal 20 (step S108), and the process ends (END). As described above, in order for the user to play the game, it is a prerequisite that the user sees the advertisement regarding the prize based on the selection of the desired prize.

As a result of the inspection, when the user is found to be an unauthorized user (step S103: Y), a message to the effect that access to the game site is denied is displayed based on the previous unauthorized activity (step S109). ) End the process.

FIG. 3 shows a flow when the downloaded game program is executed on the terminal 20. First, the game start screen is displayed on the display unit 21 of the terminal 20 (step S201). When the user starts the game (step S202: Y), "1" is added to the game execution count (step S203) and the game is executed (step S204).

In the game, symbols are scroll-displayed on the display unit 21 of the terminal 20 like a slot machine. Here, after three symbols are scroll-displayed, they are stopped and displayed one by one in a predetermined order. When all the symbols are stopped and displayed, if all three types of symbols are the same, "winning"
Becomes As a result of the game, including the case where the two symbols are in the same reach state, eventually, if all three symbols are not in the same state, the game will be lost.

When the game ends (step S205:
Y), it is determined whether or not the result of the game is a win (step S206). If the game result is a win (step S
206: Y), the game screen changes to a mail transmission screen,
An e-mail of a winning report can be sent from the terminal 20 to the server 10. When sending the winning report e-mail, the terminal 20 accepts the input of information (for example, address, name, age, occupation, etc.) relating to the prize recipient (winner), and the information and the game program in advance. The e-mail of the winning report including the authentication code embedded in the predetermined address (address) is transmitted to the server 10 (step S207). Instead of the authentication code, the game program itself may be converted into a file and used as an attachment file of the winning report e-mail.

Since the winning confirmation e-mail is returned from the server 10 which has received the winning report e-mail, the terminal 20 receives this (step S20).
8). The winning confirmation notification e-mail contains the winning number issued by the server 10. Then, the game program is set so that the game cannot be executed again, and the process is terminated (step S210). If tampering is detected in the tampering inspection performed on the server 10 side based on the transmitted e-mail of the winning report, an e-mail indicating that tampering was detected instead of the winning confirmation notification Will be sent.

If the result of the game is not a win (step S206; N), it is determined whether or not the number of executions is less than the upper limit number, and if it is less (step S209; N), the process returns to step S202, and again. Make the game executable.
If the number of executions has reached the upper limit, (step S
209; Y), and thereafter, the game program is set so as not to be executed, and the process is terminated (step S21).
0).

By setting an upper limit on the number of games that can be continuously executed on the terminal 20, if the number of games executed reaches the upper limit, even if a prize is selected on the display unit 21 of the terminal 20, the game is played. Becomes unexecutable, and prompts the user to log off from the game site 2 and connect again to the game site 2. As a result, existing users can be repeatedly attracted to the game site 2 as repeaters, and the chances of showing the updated latest advertisement can be increased.

FIG. 4 shows a process of receiving a winning report or transmitting a winning confirmation notice by the server 10. The server 10 receives the winning report e-mail from the terminal 20 by the winning report receiving means (step S3).
01), based on the authentication code included in the winning report or the game program attached to the winning report, it is checked whether the game program has been tampered with in the user's terminal 20 (step S302). For example, the presence or absence of tampering is checked by checking whether the sent authentication code matches a predetermined code, or by checking the attached game program itself with the game program that should have been sent.

If tampering is not detected (step S303: N), a winning number is assigned (step S3).
04). In addition, the assigned winning number and the information related to the prize recipient (winner) included in the received email of the winning report are stored in association with each other (step S305). Further, the electronic mail related to the winning confirmation notification including the previous winning number is returned to the sender user of the previous winning report electronic mail (step S306).

If falsification is detected (step S
303: Y), the user is registered in the database 11d as an unauthorized user (step S307). For example, when the user's terminal 20 is a mobile phone, the telephone number, the sender's mail address of the winning report, the user ID if there is a user ID, etc. are registered as information for identifying an unauthorized user. Thereafter, an e-mail indicating that the present winning is invalid because tampering has been detected is returned to the sender user of the e-mail of the previous winning report (step S308). It should be noted that identification information such as the name and ID of the game program and version information are managed in order to match with the authentication code and the game program, and at the server 10, these identification information and the authentication code or the game program itself. Are registered for verification.

FIG. 5 and FIG. 6 show the processing relating to the actual provision of prizes. When the user who wins the game receives the prize at the store, if the computer 30 of the store connects to the server 10 (step S401), the collation screen is transmitted from the server 10 and the collation screen is displayed on the display unit of the computer 30 of the store. Is displayed (step S
402).

Next, the store clerk asks the user who came to exchange the prize for the winning number and the address name, and inputs the winning number and user information from the input unit of the computer 30 of the store. The information input here is transmitted to the server 10 (step S403). The server 10 side judges whether or not the received information and the information stored in the server 10 side match, and the collation result is sent to the computer 30 and displayed on its screen (step S40).
4).

If both pieces of information match, it can be confirmed that the person is a genuine winner, and therefore the store actually provides the prize, and then transmits the prize submitted information to the server 10 (step S405). On the other hand, if both information does not match,
No prizes will be handed over. By such processing, it is possible to prevent illegal prize acquisition, and the server 1
The 0 side can also confirm whether or not the actual prize is provided.

That is, the server 10, which has received a collation inquiry from the computer 30 of the store, collates the winning number and the like, as shown in FIG. 6, and stores the information input in the store and the server side. It is determined whether certain information matches each other (step S501). Then, the collation result is returned to the computer 30 of the store (step S5).
02).

If the collation succeeds (step S50)
3; Y), the prize submission completion information is received from the computer 30 of the store, and the completion of the delivery of the prize is registered (step S504). If the collation is not successful (step S502; N), the process is terminated without registering the delivery completion (end).

When the game site operating program for realizing the processing operation of the game site operating device is executed by a computer such as the server 10, the program is stored in an auxiliary storage device such as a hard disk device in the computer. Set it in the main memory and execute it.

As described above, the game site management program is stored in a portable recording medium such as a CD-ROM for sale, or stored in a recording device of a computer connected via a network such as the Internet. It can also be transferred to another computer via a network.

Next, a second embodiment of the present invention will be described. In the second embodiment, based on the authentication code embedded in the game program, the user's terminal 20 checks whether the game program has been tampered with,
The inspection result is reported to the server 10.

FIG. 7 shows a terminal 2 according to the second embodiment.
0 processing is shown. Steps S601 to S606 are the same as those shown in FIG. 2, and a description thereof will be omitted. When the game is over and the result is a win (step S606: Y), it is checked whether the game program has been tampered with based on the authentication code embedded in the game program in advance. For example, if the authentication code is a CRC code for the entire game program, a CRC code for the entire game program is generated at the terminal 20, and this is compared with the authentication code. Determines that the program has been tampered with. Of course, CR
A checksum or the like may be used instead of the C code.

When tampering is not detected (step S608: N), the game screen is changed to the mail transmission screen, and the winning report e-mail can be transmitted from the terminal 20 to the server 10. When sending the winning report e-mail, the prize recipient (winner) on the terminal 20
Input of information (for example, information such as address, name, age, occupation, etc.) relating to the above is received, and an e-mail of a winning report including these information is transmitted to the server 10 (step S60).
9).

If falsification is detected (step S
608: Y), and since tampering has been detected, a message indicating that the winning of this time is invalid is displayed on the display unit of the terminal 20 (step S611), and thereafter, an illegal report e-mail is sent from the terminal 20 to the server 10. Is transmitted (step S612). The fraud report contains information for registering fraudulent users. For example, the mail address of the user, the telephone number of a mobile phone, and the like.

FIG. 8 shows the processing of the server 10 when an electronic mail is received from the user's terminal. If the received e-mail is a winning report e-mail (step S701: Y), a winning number is assigned (step S702), the winner information in the winning report is registered in the database (step S703), and the winning number is set. The e-mail containing the winning confirmation notification is returned to the sender of the e-mail of the winning report (step S704). If the received e-mail is a fraud report (step S705: Y), fraudulent user registration is performed based on the user information included in the fraud report (step S706).

Although the embodiments of the present invention have been described above with reference to the drawings, the specific configuration is not limited to these embodiments, and there are changes and additions within the scope not departing from the gist of the present invention. However, it is included in the present invention.

The authentication code is not limited to the one exemplified in the embodiment, and may be any code capable of checking the presence or absence of tampering.

In the embodiment, when the result of the game is a win, the server 10 sends the win number proving the win to the terminal 20 by e-mail. However, the present invention is not limited to this. In particular, when the game is played online without downloading the game program, the server 10 may simply display the winning number on the display unit 21 of the terminal 20. In such a case, the information regarding the winning numbers and the prize recipients is automatically stored in the database 11 of the server 10 when the result of the game is confirmed as winning.
