Abstract

PROBLEM TO BE SOLVED: To simplify a log-in retrial procedure to a chat server and a chat channel by generating a name to be used for participating in a prescribed system, executing a procedure for participating in the system by using the name, and when the participation procedure is failed, changing the name. SOLUTION: A connection module 14 generates an integer R of four digits by a random number. Then a log-in name obtained by adding R to three alphabetical characters (e.g. 'USR') is generated and a server 2 is logged in by using the generated log-in name 'USR+R'. Then the module 14 judges whether log-in to the server 2 succeeds or not, and when the connection is rejected, the size of R is checked. Since the R is an integer of four digits, its maximum number is '9999', and when the R is the maximum number '9999', the number can not be increased furthermore (the log-in name can not be changed), so that log-in retrial is allowed to end.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transmission medium, an information processing method and an apparatus, and more particularly to a method for generating a login name used when a client device logs in to a server or a chat channel, and generates the generated login name. The present invention relates to a transmission medium, an information processing method and an apparatus for simplifying a connection procedure by changing a login name and re-login when login is not successful.

[0002]

2. Description of the Related Art In an IRC (Internet Relay Chat) system generally used as a chat system, it is necessary to log in to a chat server and further to a chat channel in the chat server. The input parameters required to log in to the chat server and log in to the chat channel are shown in FIG.
> ”. In other words, user ID, host name, server name, real name, nickname, channel name, etc. are specified as input parameters. Most of these input parameters are etiquette when chatting What is essentially required for the connection is a nickname which is a name representing a user at the time of chatting, and this nickname also serves as a login name as shown in FIG.

[0003] Also, nicknames are required to be expressed in half-width alphanumeric characters, and the number is limited to nine characters. And the simultaneous use of the same nickname by a plurality of users is not allowed.

Further, since the IRC system has been developed for communication using ASCII character strings, there are many chat servers that can communicate only with 7-bit data. Also, IRC
In this method, no confidentiality measures are taken for the contents of the chat, and the contents are sent to the network as it is.

[0005]

As described above, since simultaneous duplication of nicknames is not allowed, a predetermined user inputs the same login name as a nickname used by another user who has already logged in. If you try to log in to a server or chat channel, you will be denied login from the server or chat channel. In this case, the user needs to enter a nickname different from the nickname whose connection has been refused, and log in again. However, if the nickname re-entered is being used by another user, the connection is refused again. As a result, there is a problem that the time required for connection is long.

[0006] The present invention has been made in view of such a situation, and enables a user to use a free name on a chat in a duplicate manner with other users, and to log in to a chat server and a chat channel. This simplifies the retry procedure.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below. In order to clarify the correspondence between each means of the invention described in the claims and the following embodiments, each means is described. When the features of the present invention are described by adding the corresponding embodiment (however, an example) in parentheses after the parentheses, the result is as follows.

That is, the information processing apparatus according to claim 13 generates a name used when participating in a predetermined system (for example, step S2 in FIG. 2).
2), procedure means for performing a procedure for participation in the system using the name generated by the generation means (for example, step S23 in FIG. 2), and change means for changing the name if the participation procedure is not successful (for example, Step S2 in FIG.
6).

However, of course, this description does not mean that each means is limited to those described.

FIG. 1 shows an example of the configuration of an information processing system to which the present invention is applied. In this specification, the term “system” refers to an entire device or a portion including a plurality of devices or portions. In this system, a plurality of client devices 1-1 to 1-3 (hereinafter, referred to as client devices 1-1 to 1-3)
When it is not necessary to distinguish each of the client devices 1-1 to 1-3, it is simply described as the client device 1.)
Is connected to the server 2 via a network 3 represented by the Internet. This server 2 adopts the IRC method and uses 7-bit visible ASCII character string data (9
(5 characters) can be used for communication. Also, the server 2 has a plurality of chat channels 21-1 to 21-3 (hereinafter, when it is not necessary to distinguish each of the chat channels 21-1 to 21-3, it is simply referred to as the chat channel 21). Is provided.

Next, the configuration of the client device 1 will be described. The client device 1 includes a transmitting unit 11 for transmitting data, a receiving unit 12 for receiving data, and a tag filter for adding tag data indicating a message of the present chat system at the time of transmission, and confirming the tag data at the time of reception. 13 and a connection module 14 for performing connection processing for logging in to the server.

The transmitting section 11 has an input section 111 for inputting a handle name and a user message and outputting the message to the message combining filter 112. The message combination filter 112 combines the handle name and the user message and outputs the combined message to the encryption filter 113. The encryption filter 113 encrypts the data sent from the message combination filter 112 and outputs the data to the tag filter 13.

The receiving section 12 decodes the data supplied from the tag filter 13,
Has a decoding filter 121 to be sent to the. The data output from the decoding filter 121 is separated into a handle name and a user message by a message separation filter 122 and sent to the display unit 123 for display.

Next, the operation will be described. First, an operation in which the connection module 14 generates a login name used to log in to the server 2 and attempts to log in to the server 2 will be described with reference to FIG.

First, in step S21, the connection module 14 generates a 4-digit integer R by using a random number. Next, in step S22, a login name is generated by adding R after three alphabetic characters (for example, “usr”) (the number of users that can be represented in this format is 10,000, and depending on the situation, You can change the number of letters of the alphabet and the number of digits of the integer to a total of 9 characters.)
In step S23, a login (connection (participation) procedure) to the server 2 is performed using the login name "usr + R" generated in step S22.

Next, the connection module 14 executes step S
At 24, it is determined whether or not the login to the server 2 is successful, and if the connection is successful, the login to the chat channel is started (the processing in that case will be described later). Is Step S2
Go to 5. In step S25, the magnitude of R is confirmed. Since R is a 4-digit integer, the maximum number is 9999. If R is smaller than the maximum number 9999, the process proceeds to step S26. If R is the maximum number 9999, the number may be further increased. No (cannot change login name by changing numbers)
So retry login.

In step S26, the value of R is incremented by one. Then, again at step S22
And join R with "usr" to generate a new login name. In step S23, login is performed again with a new login name. In this manner, the processing from steps S22 to S26 is repeated until the connection is established or R reaches the maximum number of times 9999.

In this manner, the login name is automatically generated, so that the user can save the trouble of performing the login operation. Also, usually, users often use alphabetic characters as login names,
Because few users use numbers, using numbers
Duplicate login names reduce the likelihood of a login being rejected (and thus cause a retry), as well as making it easier to change the login name.

As described above, in the present system, not only a login name is required to connect to the system, but also a login name is required to participate in a chat channel. Therefore, an operation in which the connection module 14 generates a login name used to log in to the chat channel 21 and attempts to log in to the chat channel 21 will be described next with reference to FIG.

First, in step S31, the connection module 14 checks the number N of users who are already connected to the chat channel 21, and then in step S32, three alphabetic characters (for example, "cnl").
To generate a login name with a 4-digit integer N appended. In step S32, login to the chat channel 21 is performed using the login name "cnl + N" generated in step S33.

Next, the connection module 14 executes step S
At 34, it is determined whether or not the login to the chat channel 21 has succeeded, and if the connection has succeeded, the chat is started (the processing in that case will be described later). Proceed to S35. In step S35, the magnitude of N is confirmed. Since N is a 4-digit integer, the maximum number is 9999. If N is smaller than the maximum number 9999, the process proceeds to step S36. If N is the maximum number 9999,
Since the number cannot be increased any more (the login name cannot be changed by changing the number), the login retry is terminated.

In step S36, the value of N is incremented by one. Then, again at step S32
Return to “cnl” and add N to generate a new login name. In step S33, login to the chat channel 21 is performed again with a new login name. In this way, the processing of steps S32 to S36 is repeated until the connection is established or N reaches the maximum number of 9999.

Although it is possible to make the login name used when joining the chat channel the same as the login name used when connecting to the system for the first time, the possibility of retry is reduced by changing the login name. .

As described above, when the user can log in to a predetermined chat channel, a chat is performed as follows. That is, the user operates the input unit 111 to input a handle name and a message.

The handle name and the user message input at the input unit 111 are sent to the message combination filter 112. In the message combination filter 112, the handle name and the user message sent from the input unit 112 are combined, and the data is sent to the encryption filter 113. In the encryption filter 113, the data input from the message combination filter 112 is encrypted and sent to the tag filter 13. The tag filter 13 adds the data sent from the encryption filter 113 to the
Tag data indicating a message of the present chat system is added and transmitted to the network 3.

Similarly, another client device (for example,
Data transmitted from the client device 1-2) via the network 3 is input to the tag filter 13. In the tag filter 13, it is confirmed whether or not tag data indicating that the message is a chat channel message to which the client apparatus 1-1 is logged in is added to the data transmitted from the network 3. When it is confirmed that the data is from the client device 1 on a predetermined chat channel, the tag data is removed from the data and sent to the decoding filter 121. In the decoding filter 121, the tag filter 13
Is decoded and sent to the message separation filter 122. In the message separating filter 122, the data sent from the decoding filter 121 is separated into a handle name and a user message,
Sent to 3. On the display unit 123, the handle name and the user message sent from the message separation filter 122 are displayed.

As described above, since the server 2 employs the IRC method, each client device 1 converts an 8-bit data string used for chat into a 7-bit visible ASCII character string and transmits it to the server 2. There is a need to. This process is performed by the encryption filter 113. So next,
A procedure in which the encryption filter 113 of FIG. 1 encrypts an 8-bit data string into a 7-bit visible ASCII character string will be described.

As shown in FIG. 4, the 7-bit visible ASCII character string is in the range of 20h to 7Eh. If this range is defined as a basic space, the range of 8-bit data (00h to FFh) can be expressed in the basic space. To do so, it is necessary to divide the range of 8-bit data into four spaces. Also, it is necessary to add an escape code to identify each space. A code of space 0 is used as the escape code, and the escape code is not used for any purpose other than the escape code. Therefore, this escape code cannot be used for chat.

The range of 8-bit data can be classified into the following four spaces. That is, the range from 00h to 1Fh is space 3, and the escape code representing this space is "=". The basic space in the range from 20h to 7Eh is defined as space 0. Since the data in this space is used as it is, no escape code is required. The range from 7Fh to BFh is space 1, and the escape code representing this space is "+". Further, the range from C0h to FFh is space 2, and an escape code representing this space is "-".
And

The data belonging to the space 1 to the space 3 can be obtained by subtracting 50h, subtracting 90h, or adding 30h, respectively, to obtain a 7-bit visible AS excluding an escape code.
It can be converted to data in the range of CII character strings (2Fh to 7Eh).

According to the above principle, the encryption filter 11
3 executes processing as shown in the flowcharts of FIGS.

First, in step S51, one-byte data is read from a character string to be transmitted. In step S52, it is determined whether the character string to be transmitted ends. If the character string to be transmitted does not end, the process proceeds to step S53.

In step S53, it is determined whether or not the read data belongs to space 0. If it does, the process proceeds to step S601, and if not, the process proceeds to step S54. In step S54, it is determined whether or not the read data belongs to the space 1. If it does, the process proceeds to step S611; otherwise, the process proceeds to step S55.
In step S55, it is determined whether the read data belongs to the space 2 or not.
The process proceeds to step S631, if not, to step S631.

In step S601, step S601
Data read at 51 is 7-bit visible ASCII
Converted to characters. Next, in step S602, the data converted in step S601 is referred to as ra
nd-key (converts one 7-bit visible ASCII character into another 7-bit visible ASCII character using a keyword as a parameter,
Or the inverse transform function) can be used to determine the other 7-bit visible ASCI
Converted to I character (encrypted).

In step S611, step S
The data read at 51 is subtracted by 50h,
Converted to 7-bit visible ASCII characters. Next, in step S612, the data converted in step S611 is converted into another 7-bit visible ASCII by the rand-key.
Converted to characters. Further, in step S613, an escape code “+” indicating that the data is in space 1 is added to the data converted in step S612.

In step S621, step S
The data read at 51 is subtracted by 90h,
Converted to 7-bit visible ASCII characters. Next, in step S622, the data converted in step S621 is converted into another 7-bit visible ASCII by the rand-key.
Converted to characters. Further, in step S623, an escape code "-" indicating that the data is in space 2 is added to the data converted in step S622.

In step S631, step S63
The data read at 51 is added by 30h,
Converted to 7-bit visible ASCII characters. Next, in step S632, the data converted in step S631 is converted into another 7-bit visible ASCII by rand-key.
Converted to characters. Further, in step S633, an escape code “+” indicating that the data is in space 3 is added to the data converted in step S632.

As described above, after the processing of step S602, step S613, step S623, and step S633, the next 1-byte data is read.
It returns to step S51. As described above, the processing of steps S51 to S633 is repeated until the end of the character string to be transmitted is confirmed in step S52.

In step S52, when the end of the character string to be transmitted is confirmed, in step S70 the character string converted by the function using the keyword as a parameter
By rearranging the order of the bit visible ASCII character strings by a predetermined method, the encryption is further performed, and then the encryption is terminated.

Further, referring to FIG. 10, encryption filter 113 of FIG. 1 has four arbitrary 2-byte data, AB35
The above processing will be specifically described by taking as an example a case where h, 1A77h, 6BE9h, and 11DCh are encrypted into 7-bit visible ASCII characters.
Here, the rand-key is a function for shifting one character upward (to a character represented by a larger number).

In step S51, ABh is read. Next, in step S54, it is determined that ABh belongs to space 1. Then, in step S611, ABh is subtracted by 50h to become 5Bh.
Converted to bit visible ASCII character "[". Next, in step S612, "[" is shifted upward by one character to become "$". Next, in step S613, "
Escape data “+” is added to “＼” to become “+ ＼”.

Further, in step S51, the following 1
Byte data 35h is read. In step S53, it is determined that 35h belongs to space 0. Step S
In 601, 35h is a 7-bit visible ASCII character "5"
Is converted to Next, in step S602, "
5 "is shifted upward by one character to become" 6 ".

Similarly, the processing from step S51 to step S633 is repeated six times, and the 2-byte data shown in FIG. 10 is a 7-bit visible ASCII character string "+ $ 6 = Lxl
−Z = BM ”.

Finally, in step S70, this data is rearranged to, for example, "-Z-Llx = B＼M6 = +".

As described above, 8-bit data is converted to 7-bit AS
By converting to CII visible characters, a system provided by an IRC server can use a wider range of characters for chat. In addition, the encryption can ensure the secrecy of data.

FIG. 11 shows an example of a display screen on the display unit 123 of the client device 1 in FIG. In this example, the user is chatting using the handle name “Taro”. At the lower part of the display screen, the transmitted / received message and the handle name of the user who generated the message are displayed. At the top of the screen, a space is provided for the user to input a handle name and a message. The user must enter a handle before sending the message. After entering the handle name and message, click the "Send" button,
Messages can be sent. Since the user only needs to know the handle name to chat, and does not need to know the login name, the login name is not displayed on the chat screen as shown in FIG.

However, the server 2 needs to manage the nickname and the message used by each user in association with each other. FIG. 12 shows an example of this management of the server 2.

The server 2 manages both the client device 1 that logs in in the above-described process and another client device that logs in in the same manner as the conventional method. The user with the nickname “cnl0001” connected to the chat system using the client device 1 used the login name “usr0001” when connecting to the system, but used the login name “cnl000” when participating in the chat channel.
1 ”, so the final nickname is“ cn
l0001 ". This user uses the kanji character" Taro "as the handle name. Since the handle name is not a nickname, you can use non-alphanumeric characters. In addition, the user is, "Hello, how are you?" It has occurred a message. Although the handle name "Taro" and the message are actually encrypted, the handle name and the message are shown in an unencrypted state for convenience of explanation.

The user with the nickname "ICHIRO" connected to the system by using another client device also uses "ICHIRO" as the handle name. Login name "usr000" using this client device 1
The user who logs in to the system at 2 "uses the same login name when joining the chat channel. In this chat system, the handle name is not used for login. The same handle name is used for the same chat channel. If so, the user can change the handle to another handle if necessary.

Note that the program for performing each of the above processes is F
In addition to transmission media consisting of information recording media such as D and CD-ROM,
It can be transmitted to the user via a network transmission medium such as the Internet or a digital satellite.

[0056]

As described above, the transmission medium according to the first aspect, the information processing method according to the twelfth aspect, and the first aspect.
According to the information processing apparatus described in No. 3, a name used when participating in a predetermined system is generated, a procedure for participating in the system is performed using the generated name, and when the participation procedure is not successful, Since the name is changed, the procedure for joining the system can be simplified.
