Hereinafter, when there is no need to individually distinguish the personal computers 3-1 or 3-2, they are simply referred to as personal computers 3.

Next, transmission and reception of mail via the Internet 4 will be described.

The mechanism for sending or receiving a mail via the Internet 4 is very similar to the mechanism for sending a mail such as a postcard. In the case of mail, Write a letter, 2. 2. Post to the post. 3. Transfer between post offices; One letter arrives at the recipient through the four steps of delivering to the mailbox.

In the case of mail via the Internet 4, Write an email on the email sending and receiving program,
2. 2. Press the send button of the mail sending and receiving program.
3. Transfer between mail servers After going through the four steps of pressing the receive button of the mail sending and receiving program,
The email reaches the other party.

The mail sending / receiving program is a program for writing and sending mail to the other party, or receiving the mail sent by the other party. The mail sending / receiving program is also called a mailer, and has a function corresponding to a post and a mailbox.

Most mail sending / receiving programs have an editor function for displaying mail on a screen or writing mail. The user operates the mail sending / receiving program to send or receive mail.

As a typical mail sending / receiving program,
Microsoft's OutlookExpress (TM), Qualcomm's Eudora Pro (TM), and free software Becky! InternetMail or Al-Mail32.

The mail server plays the role of a post office, so to speak. The mail server receives the mail sent by the mail sending / receiving program, and sends the mail to the mail sending / receiving program. As a typical mail server program,
There is sendmail (trademark) of Sendmail Corporation.

The mail server has three main roles. First, the mail received from the mail sending and receiving program,
Properly sending to other mail servers. Second
Is to organize and manage mails received from other mail servers by destination (user). Third, sending the managed mail to the mail sending / receiving program in response to a request from the mail sending / receiving program.

The procedure for the mail sending / receiving program to send mail to the mail server is different from the procedure for the mail server to send mail to the mail sending / receiving program, and the communication procedure is different.

The communication procedure is called a protocol. The processing by which the mail sending and receiving program sends mail to the mail server and the processing by which the mail server sends mail to the mail server include SMTP (Simple Mail Transcript).
sfer protocol) is widely used.

The processing for receiving the mail from the mail server by the mail sending / receiving program includes POP3 (Post Office
Protocol Version 3) is widely used.

In the mail server, the port corresponding to SMTP and the port corresponding to POP3 are different from each other. When sending mail, the mail sending and receiving program communicates with the mail server via the port corresponding to SMTP,
When receiving mail, it communicates with the mail server via the port corresponding to POP3.

In the case of mail, a letter transmitted from a foreign country is stamped for each country passed. Similarly, the mail is also marked with a postmark.

When a mail is transmitted, postmark information is sequentially added to the head of the mail text each time the mail passes through the mail server. Since attached to the head, this postmark information is called a header.

The header is mainly composed of three blocks. The block attached to the mail transmission / reception program is arranged in the lowermost part (the part close to the text), and the blocks attached to the mail server are arranged in the two upper parts.

The header stores new information at the top.

The header information attached to the mail transmission / reception program includes the same information as the address of the letter. From stores the mail address of the sender, To stores the mail address of the destination, and Subject stores the title.

Of the blocks attached by the mail server, Re
In ceived, a time stamp is stored. form stores the name of the mail server that passed.

The mail server sends this mail
Add Received block. Therefore, the mail server through which the mail has passed can be known by checking the description of the Received block in order from the bottom to the top.

Next, the setting of the mail sending / receiving program will be described. The information that must be set correctly in order to send mail is the e-mail address corresponding to the mail sending / receiving program and the host name of the mail server corresponding to SMTP.

The e-mail address corresponding to the mail transmission / reception program is a source address corresponding to the sender name. When the e-mail address corresponding to the e-mail transmission / reception program is not set, the recipient of the e-mail cannot know the sender, and when the destination is unknown, the e-mail cannot be returned.

The mail transmission / reception program inserts an electronic mail address corresponding to the mail transmission / reception program into the From line in the header. The e-mail address corresponding to the mail transmission / reception program is also used as a destination when the other party writes a reply. Depending on the mail transmission / reception program, the destination of the reply can be changed by setting the item of the reply address.

The host name of the mail server to which the mail sending / receiving program sends mail is set as the host name of the mail server corresponding to SMTP. When sending a mail, the mail sending / receiving program sends the mail to the mail server based on the host name of the mail server corresponding to the SMTP. The host name is described as, for example, mailserver.so-net.ne.jp.

The e-mail address and the host name are described based on the domain name. In the domain name, the country name, the type of organization, and the company name are represented by connecting “.”. In a domain name, a larger section is located later.

The e-mail address is the user's name,
It is indicated by attaching "@" as a delimiter and further connecting a domain name.

The host name is expressed by adding "." As a delimiter to the server name and further connecting the domain name.

The electronic mail address or host name is a unique mail address or host name by being described as described above.

Upper and lower case letters are used for the domain name of the e-mail address and the host name, but these are not distinguished.

Next, transmission of mail to the mail server by the mail sending / receiving program will be described. The mail sending / receiving program must obtain the IP address corresponding to the host name when sending mail. The IP address is described by a combination of a numeral and “.”, For example, 192.168.0.1.

The DNS is a system for converting a host name into an IP address. Internet 4 has several DNs
S server is installed. When a host name is sent to one of the DNS servers, the DNS server returns an IP address corresponding to the host name.

For example, the DNS server 6-1 in FIG. 1 records an IP address aaaa in association with the host name A.

The mail sending / receiving program sends the I / O of the mail server from the DNS server immediately before accessing the mail server.
Ask your P address.

Next, the procedure for sending a mail from the mail sending / receiving program to the mail server will be described. The mail sending / receiving program and the mail server send mail from the mail sending / receiving program to the mail server according to the SMTP procedure.

The procedure of SMTP is TCP (Transmission Control).
l Protocol) setup, calling the mail server, preparing for transmission, notification of destination, transmission of text, confirmation of termination,
And termination of TCP. The processing of calling the mail server, preparing for transmission, notifying the destination, transmitting the text, and confirming the end are all composed of a request from the mail transmission / reception program and a reply from the mail server.

In the SMTP processing, the mail transmission / reception program and the mail server communicate with each other using a command statement and a reply code. For example, the command statement “RCPT from:
y@so-net.ne.jp ", the RCPT is a command to notify the mail destination, and the mail destination is y@so-net.ne.jp.
jp.

In the reply code, for example, “Yes”
250. To explain some of the reply codes, 251
Indicates "No such user exists", 450
Indicates "Mailbox is in use" and 451 indicates "
452 indicates "Insufficient resources for processing" and 501
Indicates "The command syntax is incorrect."
Indicates "command not available" and 550 indicates "mailbox does not exist".

The mail has a broadcast function. The lifetime broadcast function is a function to send an e-mail with the same text to many people.

For example, if a plurality of mail addresses are described in the To line of the header, the mail sending / receiving program
The process of transmitting the PT command is repeated for each address described in the mail address.

The Cc (carbon copy) line or B
Broadcasting can also be performed using a special header such as a cc (blind carbon copy) line.

When a mail is transmitted using the Cc line or the Bcc line, the recipient of the mail knows that a copy of the mail has been received because his or her address is not described in the To line of the header. be able to.

When an e-mail is sent using the line Cc,
The header stores the mail address of the other party.
When the mail is transmitted using the Bcc line, the mail transmitting / receiving program deletes the Bcc line from the header after transmitting the RCPT command, and transmits the text. Bcc
Sending an e-mail using a line is effective when you do not want to inform the other party of the broadcast destination.

Next, a process in which the mail server searches for a mail server near the destination and transfers the mail server will be described. The process of transferring mail from the mail server to the mail server,
It is executed according to the procedure of SMTP.

In the process of transferring mail from the mail server to the mail server, the mail server sending the mail cuts out the domain name from the mail destination and sends the cut out domain name to the DNS server.

Since the DNS server records the relationship between the domain name and the host name of the mail server as an MX record, the host name of the mail server corresponding to the domain name is
Send the domain name to the mail server that sent it.

For example, the DNS server 6-2 in FIG. 1 records the host name B in correspondence with the domain name BBB.

The mail server receiving the host name sends the host name to the DNS server.

Since the DNS server records the relationship between the host name and the IP address as an A record, the DNS server transmits the IP address corresponding to the host name to the mail server that transmitted the host name.

For example, the DNS server 6-2 in FIG. 1 records the IP address bbbb in association with the host name B.

The mail server that has transmitted the IP address transmits the mail to the mail server corresponding to the domain name of the mail destination based on the above-described SMTP procedure.

The mail server can broadcast mail using a mailing list. When broadcasting mail using a mailing list, the alias function is used.

A mail server utilizing the alias function records a plurality of addresses in advance in groups corresponding to predetermined mail addresses (representative addresses). Upon receiving the mail addressed to the representative address, the mail server retransmits a copy of the mail to all of the plurality of addresses recorded corresponding to the representative address.
The mail server sends mails one after another to the registered mail addresses without rewriting the header.

The mail server corresponding to the domain name stores the received mail in a mailbox called a spool. The mail server manages the mail for each user, and distributes the mail when the receiving button of the mail sending / receiving program of the user corresponding to the destination is pressed.

The reason that the mail server does not transmit mail to the mail transmission / reception program based on SMTP may be because the device executing the mail transmission / reception program is not operating or is not connected to the Internet 4. It is.

The mail server sends mail to the mail sending / receiving program based on POP3. POP3 procedure is TC
Set up P, call mail server, authenticate user, check mailbox contents, check number of incoming calls,
The process consists of receiving the body text, requesting deletion, confirming termination, and terminating TCP. The process of calling the mail server, authenticating the user, checking the contents of the mailbox, checking the number of incoming calls, receiving the text, requesting deletion, and checking the end are all requests from the mail sending / receiving program and the reply from the mail server. It consists of.

The command text and reply code in POP3 are different from the command text and reply code in SMTP.

In POP3, mail reception processing is not executed unless the user is authenticated by the user ID and password registered in the mail server in advance.

FIG. 7 is a diagram for explaining a program executed by the PDA 1 for sending a mail. An operating system (hereinafter, referred to as an OS) 101 is a program that controls basic operations of the PDA 1.

The driver 102-1 is a program for controlling the display on the display unit 11. The driver 102-2 is
This is a program for controlling the operation of the touchpad control unit 38. The driver 102-3 is a program that controls the sound reproduction of the sound reproduction unit 42. Driver 102-4
Is a program for executing a process corresponding to the input of the jog dial 23.

The library 103 stores a plurality of processing routines used by an application program such as the mail transmission / reception program 104.

The mail transmission / reception program 104 includes the cradle 2-1 or 2-2, the personal computer 3
-1 or 3-2 and a program for sending or receiving a mail via the Internet 4.

The configuration of the program shown in FIG. 7 is the same as the configuration of a conventional program of a device for transmitting and receiving mail.

FIG. 8 is a diagram for explaining a program executed by the PDA 1 for transmitting a mail or receiving a mail. When receiving the mail from the mail server 5-2, the mail transmission / reception program 104 causes the display unit 11 to display, for example, an image shown in FIG. When displaying the received mail, the mail sending / receiving program 104 supplies the received mail to the interpreter 106.

The library 105 includes an interpreter 106
Contains the routines used when executing scripts.

[0124] The interpreter 106 is a program plugged into the mail transmission / reception program 104, extracts a script contained in the mail, and executes the extracted script. For example, the interpreter 106
In response to the execution of the script, the driver 102-1
A predetermined image is displayed on the display unit 11, and the driver 102-
3 causes the sound reproducing unit 42 to reproduce a predetermined sound.

The interpreter 106 causes the drivers 102-1 to 102-4 corresponding to the display unit 11 or the audio reproduction unit 42 to execute display or audio reproduction, etc., so that the display unit may differ depending on the model of the PDA 1. Even if the audio playback unit 11 or the audio playback unit 42 is different, the display or the audio playback by the interpreter 106 is executed reliably and accurately.

The interpreter 106 is connected to the display unit 11
Alternatively, the driver 102-1 to 102-4 corresponding to the device such as the sound reproducing unit 42 executes processing such as display or sound reproduction, so that various devices operating according to the execution contents of the script are stored in the PDA 1. Even if incorporated, the control of the device by the interpreter 106 is executed reliably and accurately.

Note that the mail sending / receiving program 104
When the script is included in the mail to be displayed, the interpreter 106 may be activated and the library 105 may be loaded.

FIG. 10 is a diagram for explaining the structure of the interpreter 106 in more detail. The interpreter 106 includes a syntax analysis module 121, an execution module 122, and an output module 123.

For example, as shown in FIG. 11, when the mail transmission / reception program 104 attempts to display the mail 151, the syntax analysis module 121 receives the mail 151 from the mail transmission / reception program 104 and includes the mail 151 in the received mail 151. The extracted script is extracted and supplied to the execution module 122.

FIG. 12 is a diagram showing an example of the structure of a mail 151 transmitted or received by the PDA 1. When the script is stored in the mail 151, the script is stored after the mail body. When the stored script requires data, the mail 151 stores data necessary for execution of the script by the interpreter 106 following the script.

The syntax analysis module 121 sends the mail 15
When data is stored together with the script in 1, the data is extracted together with the script, and the extracted data is supplied to the execution module 122 together with the script.

FIG. 13 is a view for explaining the flow of processing of the interpreter 106 when the mail 151 stores a script. When the script is extracted from the mail 151, the syntax analysis module 121 supplies the extracted script to the execution module 122.

The execution module 122 that has received the supply of the script executes the script. Output module 12
3 displays an image, outputs sound, or outputs data 171 in accordance with the result of executing the script.
Is stored in the EDO DRAM 34, for example.

On the other hand, when the syntax analysis module 121 does not extract the script from the mail 151 (when the script is not included in the mail 151), FIG.
As shown in (1), the syntax analysis module 121 causes the mail transmission / reception program 104 to execute the subsequent processing, and normal mail processing is executed. At this time, the mail transmission / reception program 104 supplies text data 191 corresponding to the body of the mail 151 to the driver 102-1. The driver 102-1 causes the display unit 11 to display the body of the mail 151 based on the text data 191.

FIG. 15 shows a mail 151 for executing Othello.
It is a figure showing the example of. In the example shown in FIG. 15, the mail 151 is composed of a text and a script. The script included in the mail 151 shown in FIG. 15 is application / x-emma described by the MIME (Multi Purpose Internet Mail Extension) method.

In the mail 151 shown in FIG.
O: "Someone"<someone@sony.co.jp>"~" Othello 2
It is a hand. "" Corresponds to the text, "------ = _ NextPart_000_0
011_01BFA9E7.2EE28580 "to" ---- Next_Part (Wed_Apr_1
9_11: 42: 48_2000_705) ---- "corresponds to the script.

FIG. 16 is a diagram schematically showing execution of a script. Execution of a script is classified into an input unit and an execution unit.

At the input unit, the syntax analysis module 1
With 21, a script is extracted from the mail 151.

The execution section further comprises a data input section, a processing execution section, and an output section. In the data input unit, the execution module 122 includes, for example, the driver 1
At 02-1, an input image is displayed on the display unit 11, and the driver 102-2 controls the input from the touch pad control unit 38.

The input in the data input unit is performed by the execution module 122 by, for example, the tablet, key 22, jog dial 23, sensor, memory stick interface 35, external keyboard, modem, USB interface 36, infrared communication unit 40, or drive 5.
This is executed by controlling the driver corresponding to the second or the like.

In the processing execution unit, the execution module 12
2 executes the processing logic of the script.

In the output section, the output module 123
Corresponds to the processing in the processing execution unit, for example, causes the driver 102-1 to display the image of the processing result on the display unit 11, and causes the driver 102-3 to output the sound of the processing result to the sound reproduction unit 42. Output.

The output from the output unit is output from the output module 123 to, for example, the display unit 11, the modem, and the audio reproduction unit 4.
2. It is executed by controlling a driver corresponding to the memory stick interface 35, the USB interface 36, the infrared communication unit 40, the drive 52, or the like.

FIG. 17 is a diagram showing an example of a script for executing the Othello game. When the script shown in FIG. 17 is read by the interpreter 106, the execution module 122 invokes the onload () method, and as shown in the example of FIG. It is displayed on the display unit 11.

As shown in the example of FIG. 19, when the user inputs a new hand, the execution module 122 obtains the coordinates on the Othello board where the new hand has been input by using the ontap () method. The execution module 12 uses the check () method to determine whether the coordinates corresponding to the new hand satisfies the requirements specified in the Othello rule, and determines that the coordinates do not satisfy the requirements specified in the Othello rule. If it is done, an error message is notified by the confirm () method (an error message is displayed on the display unit 11), and the
Repeat execution of tap () method.

If it is determined that the new hand satisfies the requirements specified in Othello's rules, the execution module 1
In step 22, the face of the frame is updated by the update () method, as shown in FIG. The output module 123
As shown in FIG. 21, by the sendmail () method,
The process of sending the mail to the other party is executed, and the process ends with the exit () method.

Next, mail transmission processing by the PDA 1 executing the mail transmission / reception program 104 will be described with reference to the flowchart in FIG. In step S11, the mail sending / receiving program 104 causes the USB interface 36 to transmit the host name corresponding to the mail server 5-1 to the DNS server 6-1 via the cradle 2, the personal computer 3, and the Internet 4, An IP address corresponding to the mail server 5-1 is obtained from the server 6-1.

The processing of steps S12 to S18 is executed, for example, based on the SMTP procedure.

In step S12, the mail transmission / reception program 104 causes the USB interface 36 to specify the IP address via the cradle 2, the personal computer 3, and the Internet 4 to connect to the mail server 5-1. In step S13, the mail sending / receiving program 104
6 calls the mail server 5-1 via the cradle 2, the personal computer 3, and the Internet 4 (calls a mail server program (for example, sendmail (trademark) or the like) executed by the mail server 5-1).

In step S14, the mail sending / receiving program 104 causes the USB interface 36 to prepare the mail server 5-1 for sending mail (procedure for sending mail to the mail server program executed by the mail server 5-1). Will be notified). In step S15, the mail sending / receiving program 104
Notifies the USB interface 36 of the destination (mail address) of the mail to be transmitted to the mail server 5-1.

In step S16, the mail sending / receiving program 104 causes the USB interface 36 to send mail to the mail server 5-1. Step S17
, The mail transmission / reception program 104 causes the USB interface 36 to confirm completion of processing with the mail server 5-1.

In step S17, the mail transmission / reception program 104 causes the USB interface 36 to disconnect from the mail server 5-1 and the process ends.

As described above, the PDA 1 is connected to the mail server 5-
1 can send an email.

The process by which the mail server 5-1 transfers the mail to the mail server 5-2 is the same as the mail transmission process except for the process of obtaining the host name corresponding to the destination of the mail. Is omitted.

Next, mail reception processing by the PDA 1 executing the mail transmission / reception program 104 will be described with reference to the flowchart in FIG. In step S31, the mail transmission / reception program 104 causes the USB interface 36 to transmit the host name corresponding to the mail server 5-2 to the DNS server 6-2 via the cradle 2, the personal computer 3, and the Internet 4, An IP address corresponding to the mail server 5-2 is obtained from the server 6-2.

The processing of steps S32 to S40 is executed, for example, based on the POP3 procedure.

In step S32, the mail sending / receiving program 104 causes the USB interface 36 to specify the IP address via the cradle 2, the personal computer 3, and the Internet 4 to connect to the mail server 5-2. In step S33, the mail transmission / reception program 104
6 calls the mail server 5-2 via the cradle 2, the personal computer 3, and the Internet 4.

[0158] In step S34, the mail transmission / reception program 104 connects the PDA 1 to the USB interface 36.
Is transmitted to the mail server 5-2 via the cradle 2, the personal computer 3, and the Internet 4 to cause the mail server 5-2 to execute a user authentication process.

In step S35, the mail sending / receiving program 104 causes the mail interface 5-2 to confirm the contents of the mailbox (in which the mail addressed to the user of the PDA 1 is stored) in the USB interface 36.

In step S36, the mail transmission / reception program 104 sends the PDA 1 to the USB interface 36.
The number of incoming e-mails to the user is transmitted to the mail server 5-2, and the number of incoming e-mails is received.

In step S37, the mail sending / receiving program 104 causes the USB interface 36 to send the mail addressed to the user of the PDA 1 to the mail server 5-2 and to receive the sent mail. In step S38, the mail transmission / reception program 104 causes the USB interface 36 to request the mail server 5-2 to delete the mail addressed to the user of the PDA 1. Mail server 5-2
Deletes the email addressed to the user of PDA1.

In step S39, the mail transmission / reception program 104 causes the USB interface 36 to confirm the end of processing with the mail server 5-2.

In step S40, mail transmission / reception program 104 causes USB interface 36 to disconnect from mail server 5-2, and the process ends.

As described above, the PDA 1 communicates with the mail server 5-
From 2, it is possible to receive a mail addressed to the user of the PDA1.

Next, the mail sending / receiving program 104 and the interpreter 106, which are executed when the mail sending / receiving program 104 displays the received mail, are executed.
The script processing of the PDA 1 will be described with reference to the flowchart of FIG. In step S51, the mail sending / receiving program 104 reads the received mail 151.

In step S52, the mail sending / receiving program 104 determines whether or not the read mail 151 includes a script. If it is determined that the script is included, the process proceeds to step S53, where the interpreter 106 to start. Mail sending and receiving program 1
04 interprets the read mail 151 into the interpreter 106
To supply.

The interpreter 106 may be activated in advance together with the mail transmission / reception program 104.

At step S54, the interpreter 1
The syntax analysis module 121 of 06 extracts a script included in the mail 151 based on the description of the mail 151. In step S55, the execution module 122 of the interpreter 106 executes the extracted script.

At step S56, the interpreter 1
The output module 123 executes display or audio output processing according to the result of the execution of the script. In step S57, the mail transmission / reception program 104 ends the interpreter 106, and the process ends.

If it is determined in step S51 that a script is not included, the processing corresponding to the script is not required, so that steps S53 to S5
7 is skipped, and the process ends.

As described above, when the script is included in the mail 151, the PDA 1 activates the interpreter 106 and executes the processing corresponding to the script.

The processing in step S52 is performed by the syntax analysis module 12 of the interpreter 106 that has been started in advance.
1 may be executed.

Next, the Othello process, which is a more specific example of script execution, will be described with reference to the flowchart in FIG. In step S71, the mail sending / receiving program 104 reads the received mail 151.

In step S72, the mail transmission / reception program 104 activates the interpreter 106. In step S73, the output module 123 of the interpreter 106 causes the display unit 11 to display the Othello board and the frame.

In step S74, the execution module 122 determines whether or not a new hand has been input. If it is determined that a new hand has not been input, the execution module 122 proceeds to step S74 until a new hand is input. And the process of the determination is repeated.

When it is determined in step S74 that a new hand has been input, the process proceeds to step S75, where the execution module 122 reads the coordinates of the new hand (indicating the position on the Othello board). In step S76, the execution module 122 determines whether the new hand satisfies the requirements specified in the Othello rule, and determines that the new hand satisfies the requirements specified in the Othello rule. If so, the flow advances to step S77 to place a frame at the position of the Othello board corresponding to the new hand.

In step S78, the execution module 122 updates the face of the frame, such as turning over a predetermined frame. In step S79, the output module 123
Displays the Othello board and the frame on the display unit 11.

In step S80, the output module 123 causes the USB interface 36 to communicate with a new hand. In step S81, the mail sending / receiving program 104 ends the interpreter 106, and the process ends.

If it is determined in step S76 that the new hand does not satisfy the requirements specified in the Othello rule, the process proceeds to step S82, where the output module 12
3 displays an error on the display unit 11 to notify the user of the error, and the procedure returns to step S74 to repeat the process from the input of a new hand.

As described above, the PDA 1 executes the Othello process based on the script included in the mail 151.

As described above, when the user attempts to read the mail 151, the PDA 1 executes the action desired by the sender of the mail 151. When the user does not read the mail 151, the PDA 1 does not execute the script included in the mail 151, so that the processing load of the script can be minimized.

Since the PDA 1 can execute various processes corresponding to the description of the script only by executing the interpreter 106, the data attached to the mail is compared with the case where the data is attached to the mail and transmitted. There is no need to store a large number of application programs corresponding to the types.

Further, since the interpreter 106 executes the script, if the interpreter 106 is securely implemented, the processing can be executed more safely than when the execution program attached to the mail is executed as it is. .

Next, a more detailed configuration of the interpreter 106 will be described.

FIG. 30 is a diagram showing an example of a more detailed configuration of the interpreter 106. As shown in FIG.

The mail parser 502, decoder 503, parser 505, data constructor 517, encoder 518, and mail generator 519 shown in FIG.
Corresponding to the syntax analysis module 121.

The script interpreter 506 in FIG.
Authentication encryption unit 507, resource access manager 50
8 and the storage module 511 correspond to the execution module 122 in FIG.

The I / O (Input / Output) module 510 in FIG. 30 corresponds to the output module 123 in FIG.

The mail transmission / reception program 104 supplies the mail 151 to be opened to the mail parsing unit 502 via the mail transmission / reception program plug-in interface 501, or acquires the mail 151 generated from the mail generation unit 519. I do.

The mail parsing unit 502 analyzes the syntax of the mail 151 supplied from the mail sending / receiving program 104 via the mail sending / receiving program plug-in interface 501, and extracts a script and data from the mail 151. Mail parsing unit 502
Supplies the script and data extracted from the mail 151 to the decoder 503.

A script is a type of program consisting of a series of instructions in which a processing procedure is described by character codes such as alphanumeric codes.

[0239] The decoder 503 decodes, for example, data encoded by a system such as Base64. Base64
Is an encoding method of binary data for converting data or a program into a sequence of 64 types of ASCII codes in order to transmit data or a program via a network transmitting only 7-bit data.

Note that the decoder 503 may decode the encoded script.

The decoder 503 is connected to the interface 50
4 to supply the script to the parsing unit 505,
The decrypted data is supplied to the script interpreter 506.

The syntax analyzer 505 replaces a predetermined character string included in the script with an intermediate code that can be processed by the script interpreter 506.
Here, when the intermediate codes are roughly classified, generally, (1)
Lexical columns, such as lexical analysis results and generated lexical columns,
(2) A tree structure such as a parse tree or syntax tree generated as a result of parsing, a tree structure such as a Polish notation, and (3) a class that is close to a machine language such as a virtual machine code called a triple or quadruple. However, in this specification, this intermediate code is used in the meaning of a parse tree.

In the Java language, the above (3) is called "byte code".

The intermediate code is an intermediate code temporarily created for convenience in the process of converting the original source code into the final executable form in the software program. By finely separating the conversion process from the source to the target in this way, it becomes easy to make the language processing system correspond to a plurality of platforms (targets).

For example, in Java, the source code is
Once converted to an intermediate code called bytecode,
The converted intermediate code is stored on the WWW server. The WWW server sends this bytecode to the WWW browser on the client side and sends it to the Java VM (Java Virt
ual Machine) interprets and executes the bytecode.
In this case, the Java VM absorbs differences between platforms (differences between CPUs and operating systems), so the bytecode itself does not depend on a specific platform. In this way, a platform-independent program environment is realized in Java while reducing the load imposed on execution (conversion from bytecode to executable code).

Also, in other high-level language compilers, instead of directly converting a source code into an execution program (usually a binary code that can be interpreted by a CPU),
Convert to intermediate code with a higher level of abstraction than the actual machine (there is no need to worry about the limitations of the actual machine architecture, so it is easier to optimize the code, etc.), and then the final executable In many cases, a method of generating a binary code is used.

The syntax analyzer 505 supplies a script in which a predetermined character string is replaced with an intermediate code to the script interpreter 506.

The script interpreter 506 supplies the script to the authentication encryption section 507, and the script
7 makes the script determine the validity.

The authentication encryption unit 507 calculates a hash value corresponding to the script by applying a hash function such as MD (Message Digest) 5 to the script. The authentication encryption unit 507 determines whether the calculated hash value and the data for authentication included in the script are the same.

FIG. 31 shows an example of a mail 151 including a script storing data for authentication.

In the mail 151 shown in FIG. 31, "<S
IGNATURE> ”and“ </ SIGNATURE> ”are data for authentication such as“ 347a9d8684ab96533fb6b51906fdacf9 ”.

Note that an electronic signature or a certificate may be stored in the mail 151 and the authentication encryption unit 507 may be authenticated based on the electronic signature or the certificate.

If it is determined that the calculated hash value is the same as the authentication data, the authentication encrypting unit 507 converts the data indicating that the script is valid, since the script has not been altered, into the script. It supplies to the interpreter 506.

If it is determined that the calculated hash value and the data for authentication are not the same, the authentication encryption unit 507 sends data indicating that the script is invalid to the script interpreter 5 because the script has been modified.
06.

The script interpreter 506 sends data indicating that the script is not valid, to the authentication encryption unit 50.
When supplied from 7, do not execute the script.

To supply.

The script execution unit 562 includes a conversion unit 611
Execute the script supplied from.

As described above, even if the transmission medium of the script is changed, the interpreter 106 can execute the script without changing the whole if only the part that depends on the transmission medium is changed.

Next, a process of executing a script attached to an e-mail by the interpreter 106 having the configuration shown in FIG. 30 will be described with reference to the flowcharts of FIGS.

[0309] In step S501, the mail sending / receiving program 104 determines whether or not the mail 151 to which the script is attached is to be displayed. If it is determined that the mail 151 to which the script is attached is not to be displayed. Returning to step S501,
The determination process is repeated.

[0310] If it is determined in step S501 that the mail 151 to which the script is attached is to be displayed, the flow advances to step S502, and the mail transmission / reception program 104 causes the mail 151 to be opened.
Is supplied to the mail parsing unit 502 via the mail transmission / reception program plug-in interface 501.

In step S 503, mail parsing section 502 extracts a script and data necessary for executing the script from mail 151 obtained from mail sending / receiving program 104. The data necessary for executing the script includes, for example, data corresponding to the value of the program counter or the value of the stack pointer indicating the execution state of the script when the script is interrupted, data indicating the arrangement of frames in the Othello game, animation , Data for updating a program, or data indicating the state of circulation of an e-mail.

[0312] The mail parsing unit 502 supplies the extracted script and data necessary for executing the script to the decoder 503.

At step S504, the decoder 50
Reference numeral 3 decodes data necessary for executing the script supplied from the mail parsing unit 502 by a method such as Base64.

At step S505, the decoder 50
3 supplies the script to the syntax analysis unit 505 via the interface 504.

At step S506, the decoder 50
3 supplies data necessary for executing the script to the script interpreter 506 via the interface 504.

At step S507, the syntax analysis unit 5
In step 05, a predetermined character string of the script supplied from the decoder 503 is replaced with an intermediate code that can be interpreted by the script interpreter 506. The syntax analysis unit 505 supplies the script in which a predetermined character string has been replaced to the script interpreter 506.

[0317] In step S508, the script interpreter 506 converts the script into an authentication encryption unit 507.
To make the authentication encryption unit 507 confirm the validity of the script. The authentication encryption unit 507 extracts, for example, authentication data included in the script supplied from the script interpreter 506, and generates a hash value by applying a hash function to the script.
The authentication encryption unit 507 determines the validity of the script based on whether the extracted authentication data and the generated hash value are the same.

The authentication encrypting unit 507 supplies data indicating whether the script is valid or not to the script interpreter 506.

[0319] In step S509, the script interpreter 506 determines whether or not the script is valid based on the data supplied from the authentication encryption unit 507. If the script is determined to be invalid, the script The process ends without executing the script because it has been modified.

[0320] If it is determined in step S509 that the script is valid, the flow advances to step S510, and the script interpreter 506 executes the script.

[0321] In step S511, the script interpreter 506 determines whether input / output, storage or reading of information, or access to an external application program is requested by executing the script. If it is determined that storage or reading of information or access to an external application program has been requested, the process advances to step S512 to execute the script
Causes the resource access manager 508 to execute input / output, storage or reading of information, or access of an external application program.

In step S513, the resource access manager 508 determines whether an input / output has been requested. If it is determined that the input / output has been requested, the process proceeds to step S514, where the input / output is Is displayed on the display unit 21 to determine whether or not to execute input / output based on the operation of the user.

If it is determined in step S514 that input / output is to be executed, the flow advances to step S515, where the resource access manager 508 executes the I / O module 5
10 to execute input / output processing such as displaying an image, and the procedure proceeds to step S516.

[0324] If it is determined in step S513 that no input / output has been requested, no input / output processing is required, so that the processing in steps S514 and S515 is skipped, and the procedure proceeds to step S516.

If it is determined in step S514 that the input / output is not to be executed, the input / output process must not be executed, and the process of step S515 is skipped.
The procedure proceeds to step S516.

In step S 516, the resource access manager 508 determines whether storage or reading of information has been requested. If it is determined that storage or reading of information has been requested, the process proceeds to step S 517, where I / O is performed. A dialog box is displayed on the display unit 21 for allowing the user to input whether or not the module 510 is to store or read the information, and whether to store or read the information based on the operation of the user. Is determined.

[0327] If it is determined in step S517 that storage or reading of information is to be performed, the process proceeds to step S517.
Proceeding to 518, the resource access manager 508
The storage module 511 is caused to execute a process of storing or reading information, such as storing data in the Flash ROM 33, and the procedure proceeds to step S519.

If it is determined in step S516 that storage or reading of information has not been requested, the processing of storing or reading information is not necessary, so that the processing of steps S517 and S518 is skipped, and the procedure proceeds to step S516. Proceed to S519.

If it is determined in step S517 that storage or reading of information is not to be performed, processing of storing or reading information must not be performed, so that the processing of step S518 is skipped, and the procedure proceeds to step S519. move on.

[0330] In step S519, the resource access manager 508 executes the schedule book program 5
12, it is determined whether or not access to an external application program such as the address book program 513, the memo pad program 514, the TODO book program 515, or the application program 516 is requested, and the access to the external application program is requested. If it is determined that the access has been made, the process proceeds to step S520, where a dialog box is displayed on the display unit 21 for allowing the user to input whether or not the I / O module 510 accesses the external application program. It is determined whether or not to access an external application program based on the operation.

If it is determined in step S520 that access to an external application program is to be executed, the flow advances to step S521, where the resource access manager 508 accesses the external application program, and the flow advances to step S522.

If it is determined in step S519 that access to the external application program has not been requested, access to the external application program is not required, and therefore, step S520 is not necessary.
And the process of step S521 is skipped, and the procedure proceeds to step S522.

If it is determined in step S520 that the access to the external application program is not to be executed, the process of accessing the external application program must not be executed.
Step 21 is skipped, and the procedure proceeds to step S52.

If there are a plurality of types of games other than the Othello game stored in the PDA 1, the user selects the game he or she wants to play on the display unit 21 and changes the identification information of the game. And sends a matching request mail to the lobby service server 801 via the Internet 4.

[0448] When the matching request mail is transmitted from the PDA 1, the lobby service server 801 similarly determines the match of the opponent based on the identification information of the game desired by the user to be played in the electronic mail. A waiting-for-match user information database 817 that manages users who have sent matching request mails to request matching.
(FIG. 54). Then, the lobby service server 801 searches the waiting-for-match user information database 817 and, when determining that there is another user who wants to play the same game, matches the two users.

[0449] For example, the user of the PDA 1-1 sends an inquiry request mail for the Othello game, and the PDA 1-1
Similarly, if the user of the PDA 1-2 has transmitted the matching request mail about the Othello game before the user of the PDA-1, the lobby service server 801 sets the PDA
A match is made between the user 1-1 and the user of the PDA 1-2 so that a match in the Othello game can be made.

Then, PDA1-1 and PDA1 that were agreed
The -2 user can alternately input pieces as described with reference to FIG. 51 or FIG. 52, transmit and receive an e-mail including the Othello game script 531 and play the Othello game.

Also, the lobby service server 801 performs processing such as converting the e-mail address of an e-mail transmitted and received between the matched users so that the opponent does not know the identity of the matched user. Do.

That is, the electronic mail including the arrangement information of the frames input by the user of the PDA 1-1 is not directly transmitted to the PDA 1-2 but is transmitted once to the lobby service server 801 and the mail address of the PDA 1-1 ( For example, "aaa.n
e.jp ") is converted to, for example, a mail address of the lobby service server 801 (for example," server.co.jp "), and then transmitted to the PDA 1-2. Similarly, the e-mail transmitted from the PDA 1-2 is transmitted to the lobby service server 801.
In the mail address of the PDA 1-2 (for example, "bb
b.ne.jp ") is converted to the mail address of the lobby service server 801 (for example," server.co.jp "),
Sent to PDA 1-1.

[0453] Thus, the users who have been invited as opponents can each compete in the game without knowing their personal information such as their mail addresses. In other words, it is possible to prevent a so-called mischief mail or the like from being transmitted from the opponent after the battle of the game ends.

FIG. 54 is a block diagram showing a configuration example of the lobby service server 801.

[0455] The CPU 811 controls the overall operation of the lobby service server 801 according to a program stored in the ROM 812 or a program loaded from the storage unit 820 into the RAM 813. RAM 813 also contains C
Data and the like necessary for the PU 811 to execute various processes are appropriately stored.

[0456] CPU 811, ROM 812, and RAM 813
Are connected to each other via a bus 814. The input / output interface 815 is also connected to the bus 814. And this input / output interface 8
15 are connected to various devices.

The user information database 816 during the battle is
Inquired and records information about users in battle. As in the above example, the user of PDA1-1 and PDA1-
When two users are referred to and are fighting, their email addresses, information identifying the type of game being played, and the like are recorded.

[0458] Matching waiting user information database 817
Records information about the user waiting for the match with the opponent. For example, if the matching request mail is transmitted from the PDA 1-1 and there is no other user requesting a match in the same game, the match waiting user information database 817 stores the PDA 1 as information on the match waiting user. -1 is recorded, and identification information of a game that the user of the PDA 1-1 desires to play is recorded.

That is, when the match request mail is transmitted, the CPU 811 (competition user search program 843 (FIG. 55) described later) determines the same game based on the game identification information included in the e-mail. It is determined whether or not there is another user requesting the opponent by searching the information recorded in the battle waiting user information database 817.

[0460] Then, the information recorded in the waiting-for-combat user information database 817 as the information about the waiting-for-combat user is moved to the in-combat user information database 816 when it is matched with the opponent.

The input unit 818 is composed of a keyboard, a mouse, and the like, and is operated by the administrator of the lobby service server 801. The output unit 819 is a CRT (Cathode Ray Tu
be), a display such as an LCD, a speaker, etc., and provides various information to an administrator of the lobby service server 801. The storage unit 820 is configured by a hard disk or the like, and stores, for example, a program executed by the CPU 811 and various information.

The communication unit 821 is composed of a modem, a terminal adapter, and the like, and is connected to the Internet 4 and, for example, a matching request mail transmitted from the PDA 1-1 to 1-N or a connection between the two matched PDA 1s. Receive email sent and received by. Then, the communication unit 82
No. 1 indicates that the email address of the email sent and received between the two PDA 1s converted by the CPU 811 (mail address conversion program 845) is
The data is transmitted to the PDA 1 designated as the transmission destination.

The input / output interface 815 also has
A drive 822 is connected as necessary, and a magnetic disk 823, an optical disk 824, a magneto-optical disk 825, a semiconductor memory 826, or the like is appropriately mounted, and a computer program read therefrom is stored in the storage unit 820 as necessary. Installed.

FIG. 55 is a functional block diagram showing an example of a program executed by the CPU 811. The various programs illustrated in FIG. 55 are realized, for example, by expanding a program stored in the ROM 812 or a program stored in the storage unit 820 into the RAM 813.

[0465] The mail transmission / reception program 841 is a PDA1
The communication unit 821 receives and receives the e-mail transmitted by the communication unit 821 via the input / output interface 815 and the bus 814. In addition, the mail transmission / reception program 841 controls the communication unit 821 to transmit e-mails whose e-mail addresses have been changed, which are transmitted and received between the inquired PDA 1, for example.

The e-mail obtained by the mail transmission / reception program 841 is stored in the database management program 841.
2, or supplied to the mail address conversion program 845.

The database management program 842 manages information stored in the battle user information database 816 and the battle waiting user information database 817. For example, the database management program 842
When the match request mail is supplied, the opponent is searched by the opponent user search program 843 in the subsequent stage, and when it is determined that there is an opponent, information on the matched user is compared The information is recorded in the information database 816.

On the other hand, the database management program 842
If the match user search program 843 determines that there is no opponent, the match request mail is sent to the user waiting for the match, for example, the PDA1 mail address and the identification information of the game desired to be matched. The information is recorded in the information database 817.

[0469] In response to an instruction to search for an opponent from the database management program 842, the opponent user search program 843 determines the game identification information included in the e-mail sent from the PDA 1 (the user can play the opponent). Based on the desired game identification information), a search is made in the battle waiting user information database 817.

[0470] If it is determined that there is another user who is searching for an opponent of the same game in addition to the user who transmitted the match request mail, the match user search program 843 matches both users. , And notifies the database management program 842 of information on both users. Also, the information about the two users who have been matched is notified to the mail generation program 844.

[0471] The mail generation program 844 generates an e-mail for notifying that an opponent has been found, for example, to both users matched by the opponent user search program 843, and sends it via the mail transmission / reception program 841. To send.

[0472] The mail address conversion program 845 is
The e-mail address containing the script, which is transmitted and received to play the game between the paired PDAs 1, is converted to, for example, the e-mail address of the lobby service server 801. For example, PDA1-1 to PDA1-
When the e-mail sent to the e-mail 2 is supplied from the e-mail transmission / reception program 841, the e-mail address conversion program 845 sends the e-mail address of the PDA 1-1 (for example, “aaa.ne.jp”) to the lobby service server 801.
(For example, “server.ne.jp”). The e-mail whose e-mail address has been converted is output to the e-mail transmission / reception program 841 and transmitted to the PDA 1 designated as the destination.

The game battle program 846 includes, for example,
Compete with a user waiting for a match with an opponent in a predetermined game. That is, the user recorded in the battle waiting user information database 817 can play against the game battle program 846 until the user is matched with the opponent. Naturally, the user of the PDA 1 can also access the lobby service server 801 to play the game battle program 846.

First, with reference to the flowchart of FIG. 56, the processing of the PDA 1 for transmitting a matching request mail to the lobby service server 801 will be described.

In step S3001, the mail generation unit 519 in FIG. 30 stores the script generated and supplied by the script interpreter 506 and data such as game identification information, for example, as described above. Generate request email.

[0476] In step S3002, the mail sending / receiving program 104 sends the matching request mail supplied from the mail generating unit 519 via the mail sending / receiving program plug-in interface 501 to the lobby service server 801. The process of transmitting the matching request mail is executed, for example, by operating a predetermined button (tapped by the user) displayed on the Othello game screen.

In step S3003, the mail transmission / reception program 104 shown in FIG. 30 is transmitted from the lobby service server 801 via each unit as described above.
It is determined whether an e-mail notifying that the opponent has been found has been received, and the process waits until it is determined that the e-mail has been received.

[0478] If the mail transmission / reception program 104 determines in step S3003 that the e-mail transmitted from the lobby service server 801 has been received notifying that the opponent has been found, the process proceeds to step S3003.
Proceed to 4. The data contained in the received email is
As described above, it is supplied to the script interpreter 506 via each unit.

[0479] In step S3004, script interpreter 506 controls I / O module 110 to cause display unit 21 to display a message included in the electronic mail.

FIG. 57 shows that in step S3004,
FIG. 3 is a diagram showing an example of an e-mail displayed on a display unit 21. As shown in the figure, for example, a message such as "An opponent has been found. Please compete in the Othello game" is displayed.

Then, in step S3005, a match of the Othello game is executed with the matched user. The processing executed in step S3005 is basically the same as that in FIGS. 52 and 53 except that the e-mail address of the opponent is converted and displayed, for example, to the e-mail address of the lobby service server 801. Since this is a process, its description is omitted.

Next, the opponent matching process of the lobby service server 801 will be described with reference to the flowcharts of FIGS. 58 and 59.

In step S3011, the mail transmission / reception program 841 controls the communication unit 821 to
Receives the matching request email sent from.
The sender of the e-mail is included in the matching request email
It contains the email address of the PDA 1 and the identification information of the game that you want to play. Then, the mail transmission / reception program 841 outputs the obtained matching request mail to the database management program 842.

In step S3012, the database management program 842 determines whether the
The identification information of the game included in the matching request mail supplied from 41 is acquired (extracted). And
The database management program 842 notifies the match user search program 843 of the identification information.

In step S3013, the match user search program 843 to which the game identification information has been notified searches the match waiting user information database 817 based on the identification information. Then, step S301
In 4, it is determined whether or not there is another user waiting for a match for the same game as the user who transmitted the matching request mail.

[0486] If it is determined in step S3014 that the opponent user search program 843 has no opponent, the process proceeds to step S3015, where the information on the user who transmitted the e-mail is used as the information on the user waiting for the battle, as the user information database. 817. For example, the mail address of the PDA 1 and the identification information of the game for which a match is desired are recorded in the match waiting user information database 817.

Thereafter, the flow returns to step S3011 and the subsequent processing is repeatedly executed.

On the other hand, in step S3014, the opponent user search program 843 has an opponent (there is another user registered in the opponent waiting user information database 817 in association with the same game identification information).
If it is determined, the process proceeds to step S3016. And
The opponent user search program 843 notifies the database management program 842 that an opponent has been found.

[0489] In step S3016, the database management program 842 matches both users based on the notification from the battle user search program 843, and retrieves the information of the searched user (the user waiting for the battle) and the current time. Then, the information on the user who transmitted the matching request mail is recorded in the user information database 816 during battle as information on the user during battle.

[0490] For example, the user of the PDA 1-1 transmits an Othello game matching request mail, and the information on the user of the PDA 1-2 is stored as the information on the user waiting for the Othello game in the battle waiting user information database 8.
17 is registered, the database management program 842 causes the in-flight user information database 817 to record the email addresses of the PDA 1-1 and PDA 1-2.

Then, in step S3017, the mail generation program 844 generates an e-mail notifying that the opponent has been found to the PDA 1 used by the inquired user, and sends the e-mail to the PDA 1 via the mail transmission / reception program 841. Send to

As in the example described above, when the user of the PDA 1-1 and the user of the PDA 1-2 are referred to as opponents, the mail generation program 844 causes the communication unit 821
To generate and send an e-mail notifying the PDA 1-1 and PDA 1-2 that an opponent has been found. Thereby, the user of the PDA 1-1 and the PDA 1-2
Of users can compete in, for example, an Othello game.

In step S3018, the mail generation program 844 determines, for example,
An e-mail is generated to prompt the PDA 1 to input an Othello frame first, and the e-mail transmission / reception program 841
To send over. That is, for example, in the case of a game in which hands are input alternately, such as an Othello game, among the matched users, the user who has transmitted the matching request mail to the lobby service server 801 first (waiting for a match) User) is the first player.

For example, as described above, when the user of the PDA 1-2 is waiting for a match, and the user of the PDA 1-1 sends an inquiry request mail, and the user of the PDA 1-2 is invited to the match, the PDA 1-1 The second user inputs the first move. Naturally, the first user and the second user may be determined by e-mail or the like between the two users who have been contacted.

In the PDA 1 on the leading side, for example, an Othello game board is displayed on the display unit 21 by the above-described script processing, and the user inputs (places) a frame by a predetermined operation. Then, the mail sending / receiving program 84
1 controls the communication unit 821, and in step S3019, transmits the e-mail including the frame arrangement information (the input frame position information on the Othello game board) transmitted from the PDA 1-1 on the leading side. Receive.

[0496] The mail transmission / reception program 841 outputs the received e-mail to the mail address conversion program 845.

The mail address conversion program 845 is
In step S3020, the mail address of the e-mail supplied from the mail address transmission / reception program 841 is converted into, for example, the mail address of the lobby service server 801 and the mail transmission / reception program 841 is executed.
To the PDA 1 on the back side.

That is, for example, the e-mail address “bbb.ne.jp” of the e-mail including the frame arrangement information, which is input by the PDA 1-2 and transmitted to the PDA 1-1, is
The email address of the lobby service server 801 "serve
r.co.jp ".

[0499] Therefore, after receiving the e-mail transmitted via the lobby service server 801, the PD on the hand side
In A1-1, the mail address of the lobby service server 801 is displayed without displaying the mail address of the PDA 1-2 on the leading side. Also, on the rear PDA 1-1, a frame input by the user of the front PDA 1-1 is displayed on the Othello game board.

Then, the user of the PDA 1-1 on the back side is
A frame is input (placed) in accordance with the position of the frame input by the user on the leading side.

[0501] An e-mail including frame arrangement information input by the user of the PDA 1-1 on the rear side is transmitted to the lobby service server 801 via the Internet 4.

[0502] In step S3021, the mail transmission / reception program 841 controls the communication unit 821 to receive the e-mail transmitted from the PDA 1 on the back side. The received e-mail is sent to the PDA
1 is supplied to the mail address conversion program 845 in the same manner as the e-mail transmitted from 1.

[0503] The mail address conversion program 845 is
In step S3022, similarly to the processing in step S3020, the e-mail address of the e-mail transmitted from the PDA 1 on the back side is converted into, for example, the e-mail address of the lobby service server 801, and the mail is sent to the PDA 1 on the front side. The data is transmitted via the transmission / reception program 841.

[0504] In step S3023, the database management program 842 checks the e-mail transmitted and received between the PDA 1 in the battle, determines whether or not the Othello game has ended, and if it determines that the Othello game has not ended, Returning to step S3019, the subsequent processes are repeatedly executed.

On the other hand, in step S3023, when the database management program 842 determines that the match of the Othello game has ended, the database management program 842 deletes the information on the user who was playing the match, which is recorded in the user information database 816 during the match. Thus, the processing is terminated.

[0506] By the above processing, the inquired users do not share their PDA1's e-mail address with their opponents. It is possible to prevent a mischievous electronic mail from being sent.

[0507] Also, the administrator of the lobby service server 801 can acquire information such as which user likes which game,
For example, it is possible to distribute an advertisement mail related to a game in accordance with each user's preference.

[0508] As described above, the lobby service server 801 may provide a user waiting for a battle with the game battle program 846. For example, when the game played by the game battle program 846 is the Othello game, the position information of the pieces generated by the game battle program 846 is:
The electronic mail is supplied to the mail generation program 844 to generate an electronic mail with an Othello game script attached thereto, and then the electronic mail is transmitted to the PDA 1 used by the user waiting for the battle.

[0509] Then, an e-mail requesting a match with the opponent is newly received, and the game specified by the e-mail is currently in the game competition program 84.
In the case where the user who is fighting with the game No. 6 is the same as the game that the player wants to fight, the battle with the game fighting program 846 is ended, and the user who sent the e-mail is referred to.

[0510] In the above example, the game to be played is the Othello game. However, any game can be played as long as the game can be played by sending and receiving electronic mail. Further, the game battle is realized by two users, but may be realized by a larger number of users.

[0511] Further, as long as the terminal can be connected to the Internet 4, any terminal that performs the battle may be used.
That is, the above-mentioned lobby service can be used by operating a personal computer or a mobile phone (digital mobile phone with camera 301).

The series of processes described above can be executed by hardware, but can also be executed by software. When a series of processing is executed by software, a program constituting the software can execute various functions by installing a computer built into dedicated hardware or installing various programs. It is installed from a recording medium into a possible general-purpose personal computer or the like.

As shown in FIG. 54, a recording medium for recording a program installed in a computer and made executable by the computer includes a magnetic disk 823 (including a floppy disk) and an optical disk 824.
(CD-ROM (Compact Disc-Read Only Memory), DVD (Dig
Ital Versatile Disc), magneto-optical disc 825
(Including MD (Mini-Disc)) or semiconductor memory 8
26 or Flash ROM 3 in which programs are stored temporarily or permanently
3 and a hard disk (storage unit 820 (FIG. 54)). The recording of the program on the recording medium
This is performed using a wired or wireless communication medium such as the public line network 202, the local area network, the Internet 4, or digital satellite broadcasting via an interface such as a router or a modem as necessary.

[0514] In this specification, the step of describing a program to be recorded on a recording medium may be performed in a chronological order according to the described order. This also includes processing executed in parallel or individually.

[0515] In this specification, the system is
It represents the entire device composed of a plurality of devices.

[0516]

According to the information processing apparatus and method, the recording medium, and the program of the present invention, a first e-mail transmitted from an information processing terminal via a network and requesting selection of an opponent of a game. And the identification information for identifying the game, which is included in the received first electronic mail, and the mail address of the information processing terminal are stored in association with each other. Also, based on the identification information, it is determined whether there is another information processing terminal which is a game opponent and stored in association with the same identification information, and it is determined that another information processing terminal exists. In this case, a second e-mail for executing the game, which is transmitted and received between the information processing terminal and another information processing terminal, is received. Further, the first e-mail address for identifying the transmitting terminal of the received second e-mail is
The second e-mail converted to the second e-mail address and converted to the first e-mail address of the transmitting terminal is transmitted to the information processing terminal or another information processing terminal designated as the transmission destination. So that your opponent does not know your personal information such as your email address,
You can play network games.
