JPH1153313A - Registered terminal identification method and device therefor - Google Patents

Abstract

PROBLEM TO BE SOLVED: To discriminate the communication terminals without using plural different user IDs, password numbers, etc., by adding a discrimination ID to a user ID when an access is carried out via a 1st terminal and using only a user ID when an access is carried out via a 2nd terminal. SOLUTION: A member 11 who is previously registered at an information management center 1 acquires a navigation CD-ROM to receive the services of the center 1 and also decides a user ID and a password number. When a navigation device 8 sends a message to the center 1, the user ID and password number are authenticated by an authentication server 3 via an access server 2 of the center 1. When the member 11 accesses the center 1 via a personal computer 9, he starts a personal computer CD-ROM to input the same user ID and password number as those which are used by the device 8. Then a discrimination ID is automatically added to the user ID of the personal computer CD-ROM.

In order to achieve the above-mentioned object, an invention according to claim 1 of the present invention is provided when an information management center can be accessed by a plurality of terminals by the same user. A method of identifying a registered terminal, wherein when the same user uses one user ID, when the first terminal accesses the information management center, the first terminal uses the identification ID as the user ID.
When accessing the information management center using the second terminal, the gist is that only the user ID is used, and the information management center authenticates the user authentication including the identification ID.

According to the first aspect of the present invention, when a user accesses the information management center with a terminal normally used,
When authentication is performed with a standard ID (= A) and the information management center is accessed with a terminal other than the above, the terminal automatically assigns an ID (= A +) to the ID (= A +
Since the authentication is performed in S), even if the user is the same user and the user ID used by the user is the same, different services can be used or access can be rejected for each terminal type used.

When the identification ID is obtained, the user ID composed of alphanumeric characters is divided into an alphabetic part and a numeric part, and each character of the alphabetic part is converted into a number whose correspondence is arbitrarily set in advance. , The sum is divided by a value p (arbitrary natural number), and the resulting remainder is converted back to alphabetic characters based on the correspondence,
This is defined as X, the sum of the numbers is divided by the value m (positive integer) for the number part, the obtained remainder is defined as Y, and X and Y are added to the user ID as identification IDs. ID.

[0009] The invention according to claim 3 of the present invention is a registered terminal identification device when an information management center can be accessed by a plurality of terminals by the same user. When accessing the information management center using an ID and the first terminal, the user ID is added to the user ID at the first terminal.
When only the user ID is used when accessing the information management center using the second terminal, whether or not an identification ID is added to the user ID for access to the information management center Determining means for determining whether or not the user ID is added to the user ID when the determining means determines that the user ID is added to the user ID. That is the gist.

As a result, the same user is assigned the same user I
Even if the information management center is accessed using a plurality of terminals using D, different services may be used or access may be rejected for each terminal type used, depending on the identification ID. Can be.

[0011]

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

FIG. 1 is a diagram showing a configuration according to an embodiment of a system to which a registered terminal identification method of the present invention is applied.

As shown in FIG. 1, an information management center 1 as a center server includes an access server 2 and an authentication server 3.
And the application server 4, and is connected to the network 5 via an arbitrary communication line (wireless / wired). This network 5 is a so-called mobile phone, PH
S, a public network, a dedicated line, the Internet, or the like.

The information management center 1 has the following functions. Function to accept access from general-purpose terminals and special terminals. Function to identify user ID and password.

The mobile body 6 is a vehicle (two-wheel or four-wheel), and includes a mobile phone (including a PHS; hereinafter, these are simply expressed as mobile phones) 7 as a general-purpose terminal and a navigation device (so-called “mobile phone”) connected thereto. Car navigation system) 8 is installed.

The general-purpose terminal has the following functions. A function to enter and issue a user ID and password for identifying an access user. Function to access the center server (information management center 1).

A personal computer 9 (PC (Pe
RPC (Personal Computer), PDC) is connected to the network 5 via an arbitrary communication line (wireless (including infrared rays, etc.) / wired) and has a CD-RO as a storage medium.
A large-capacity device such as M or DVD is prepared. Here, a case where a CD-ROM is used will be described as an example.

The special terminal has the following functions. A function to enter and issue a user ID and password for identifying an access user. A function to add an identification ID unique to a special terminal to a user ID. A function that can issue a user ID and password to which an identification ID unique to a special terminal is added. Function to access the center server.

The outline of the operation of the entire system will be described below.

A member 11 registered in advance in the information management center 1 obtains a navigation CD-ROM to receive the service of the information management center at the time of member registration, and also enters a user ID (= A) and a password. I have decided. The navigation device 8 mounted on the moving body (vehicle) 6 has a communication function, and can perform data communication with the information management center 1 using the mobile phone 7. When a call is transmitted from the navigation device 8 to the center, the user ID and the password are authenticated by the authentication server 3 through the access server 2 of the center. When authenticated, the navigation application stored in the application server 4 can be used.

The member 11 can receive the service of the information management center 1 using not only the navigation device 8 but also the personal computer 9 provided in the office or at home. In this case, the CD-RO for the personal computer is
M10 is obtained in advance. Here, the same user ID used when using the navigation device 8 is used as the user ID.

When the member 11 accesses the information management center 1 through the personal computer 9, as shown in FIG.
First, in step S15, the same user ID (= A) and personal identification number used in the navigation device 8 are input. The activated CD-ROM software is stored in step S17.
Then, S of the identification ID is automatically given to A of the user ID. Therefore, when transmitting from the personal computer 9 to the information management center 1, the user ID is transmitted as A + S. When the authentication server receives the user ID (= A + S),
By recognizing the use from the personal computer 9, the personal computer dedicated service is provided (step S19).

If the use of the communication line is above a certain level and there is no room for the use of the communication line, the connection from the personal computer is disconnected. Of course, it is also possible to restrict the use from the reverse navigation device 8.

Next, a method of adding an identification ID (= S) to a user ID will be described.

First, the user ID (= A) for the personal computer 9
The method for obtaining the following will be described. Here, the navigation ID (alphanumeric characters) is divided into alphabetic and numeric characters, each character is converted into a number according to the conversion rule, and the sum is divided by the value p (arbitrary natural number) of the number of characters set in the conversion rule. , The remainder obtained is converted to an alphabetic character by the conversion rule, and this is set to X, while the sum of the numbers is divided by the value m (positive integer) of the number of numbers used in the conversion rule, and the obtained remainder is Y S (XY) is added to the ID to obtain a personal computer ID.

1. Navigation ID (6 alphanumeric characters)
Characters) into alphabets and numbers.

Alphabet portion: -1: Each character is converted into a number according to the conversion rule, and the sum is divided by the number 52 of twice the number of 26 English characters (the sum of uppercase and lowercase numbers). −2: The remainder is converted back to alphabetic characters according to the conversion rules, and this is set to X.

Numerical part: −1: The sum of the numbers is divided by 10. −2: The remainder is Y.

2. X and Y are added to the original ID to obtain an ID of eight half-width alphanumeric characters.

[Alphabetic and numeric conversion rules] A: 0 B: 1 H: 7 Y: 24 Z: 25 a: 26 b: 27 c: 28 y: 50 z: 51 , 0: 0 1: 1 2: 2 9: 9 Next, a specific example will be described. Here, it is assumed that the navigation user ID is 0AXK68.

English letters:

A (0), X (23), K (10): 0 + 23 + 10 = 33 mod (33, 26) = 7 → H Numerical part: 0 + 6 + 8 = 14 mod (14, 10) = 4 The user ID is as follows.

Before conversion 0AXK68 After conversion 0AXK68H4 For simplicity of explanation, the navigation user ID is made up of 6 characters, but it goes without saying that the number of characters is not limited in this embodiment.

Next, another example of the above algorithm will be described.

The information management center 1 can manage a normal ID (= X) of a certain user and a value (X + S) obtained by adding a special terminal ID (= S) to X.

When a certain user accesses the information management center 1 with the navigation device 8 (general-purpose terminal), authentication is performed with a normal ID. When accessing with the personal computer 9 (special terminal), authentication is performed with X + S.

Here, if only the information management center 1 is permitted to access a certain user from the personal computer 9, the user ID at the time of access by the navigation device 8 is not managed, so that the same user can Even if there is, authentication can be disabled.

1. The ID provided to the user (six single-byte alphanumeric characters) is divided into alphabetic characters and numeric characters.

Alphabet part: -1: Each character is converted into a number according to the conversion rules, and the sum is divided by 26. −2: Add the remainder [Remainder A] to each character (after digit conversion). -3: The remainder obtained by dividing the value by 26 (the number from A to Z) is converted back to alphabetic characters according to the conversion rules and used.

Numerical part: −1: The sum of the numbers is divided by 10. −2: The remainder obtained by adding the remainder [Remainder B] to each and dividing by 10 is used. -3: [Remainder A] is added before the converted character, and [Remainder B] is added after.

[Alphabet and Number Conversion Rules] A: 1 B: 2... Y: 25 Z: 26 As described above, with the spread of the intranet, a user or service remotely accessing an in-house server or the like from the outside. In this embodiment, the general user ID is used at the time of access from the general-purpose terminal, and the special terminal identification ID is added to the normal user ID at the time of the access from the special terminal. And special terminals. As a result, even when the same user ID is issued, the connection between the special terminal and the general-purpose terminal and the service to be provided can be distinguished.

In the above description, the case where the combination of the navigation device and the personal computer is used has been described as an example. However, the present invention is not limited to this. For example, the combination of a portable personal computer, a PDA, a workstation, etc. Of course, it may be. In addition, the medium for receiving the service is not limited to the CD-ROM, and another medium such as a floppy disk, an MO, or the like may be used.

[0042]

As described above, according to the present invention, the same user and the user ID used by the user
However, the same service can be used for different terminal types to be used, and different services can be used, and access can be denied.
