Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a method for connecting a communication line between a computer, etc. and its terminal, and particularly to a communication line that can prevent unauthorized use of the computer, etc. from the terminal. This relates to the connection method.

[Prior art and its problems]

Traditionally, when computers, etc. (hereinafter referred to as computers) were to be used jointly from terminals in remote locations using communication lines, dedicated lines were installed in the same company or group to connect the computers and terminals. Ta. However, in recent years, as the processing power of computers has improved and the number of users has increased, the number of terminal devices has increased rapidly.

In Central Africa, computer-based voice response services currently being planned for banks and other institutions will be used for general home appliances.

It is said that it will be possible to use computer-based services from the stuffing machine. When providing computer services to such a large number of terminals, it is an economical burden to install a dedicated line for each terminal. Therefore, in such a case, it is clear that it is better to use a public line.

However, in the case of a dedicated line, the computers that can be used are limited to the terminal connected to the dedicated port 11, whereas in the case of a public line, a third party's terminal can be used via the exchange. There is a possibility that it will be connected.

Conventionally, when using a computer from a terminal, in order to confirm the terminal or confirm the user, the terminal usually sends a message such as the terminal number or user number (hereinafter these two numbers are abbreviated as ID). A measure is taken to prevent unauthorized use by a third party by entering the code number of the computer and comparing it with a code that has already been registered in the computer.

However, if this ID is known to a third party, there is a risk that the computer will be used illegally.

However, when using a public line, there is currently no way to confirm the other party other than checking the ID.

[Purpose of the invention]

The present invention was created in view of these circumstances, and its purpose is to provide a method that can prevent unauthorized computer use with a much higher degree of accuracy than ever before, with a very simple device configuration. It is in.

[Summary of the invention]

The present invention provides the computer with the ID of the user or terminal.
In response to this, register the dial number of the user or terminal in advance, and when the line is connected in response to a call or LK from the terminal, the above ID will be entered on the computer side.
After inputting 1, the line is forcibly disconnected and the input ID is
The line is connected again from the computer side and the terminal is called using the registered dial number corresponding to the .

〔Effect of the invention〕

According to the present invention, a public line is used as a communication line between a computer and a terminal, and the line is connected only to terminals registered in advance, like a conventional private line.

Therefore, even if a third party learns the terminal number or user number used to use the computer, it not only prevents the third party from using the computer illegally, but also makes it economical to use public lines. It can also be expected to have a positive effect.

[Embodiments of the invention]

An embodiment of the present invention will be described below.

FIG. 1 is a schematic configuration diagram when the line connection method of the present invention is applied to a computer system having a voice response device.

In FIG. 1, 1a, 1b, . These telephones connect to the public telephone line and the exchange 2 in the telephone office.
A normal call can be made between any telephones. 3
is a computer system installed within banks, etc.
The line connection device 3a can also be used to perform data communication with terminals at other branches (not shown), for example, by using the public telephone line network. A voice response device 3b is connected to the computer system 3, and is configured to automatically provide deposit notifications, balance inquiries, and other services to depositors 9.

Next, the operation of this system will be explained. FIG. 2 is a diagram illustrating a computer system to which the present invention is applied and the usage status of its users.

For example, an elderly user calls up the computer system 3 by dialing the Senkou computer system using the telephone 1a at the user's home. As shown in FIG. 1, an appropriate number of lines are connected to the exchange 2 according to the traffic of the computer system 3, and the exchange 2 selects an empty line, 11! The I u machine 1a and the computer system 3 are connected.

The line tangent device i 3 a performs connection for calls from the line in the computer system 3.

When the connection is completed, the computer 3C is connected via the control line 3d.
is notified, the instruction from the computer 3C is transmitted from the control line 3e to the voice response device 3b, and the response message "
Please enter the name of the service and it will be communicated to the elderly person using the service. Here, the elderly user sends, for example, a code number 4 RORO KU for checking the balance from the phone. This code number is input as a dial signal to the computer 3C via the line connection device 3a, and the computer 3C decodes this code number and learns that the elderly person is requesting a balance inquiry. In response, the response device 3bK instructs the response device 3bK to send a message saying, "This is an inquiry about Kumadaka from the computer 3cH response (■)...". User A uses this message to input his passbook number and code number via the telephone. The computer 3c that entered this information in the same way as above checks whether the passbook number and PIN number match those registered in advance.If they match, it responds (Rino1 hangs up and waits). After this message is sent, the line is temporarily disconnected from the computer system 3 of user A1.

After that, after a predetermined period of time, the computer 3C instructs the line connection device 3a to dial the telephone number of user A that has been registered in advance in correspondence with the passbook number, and the line connection device 3a performs the dialing operation. , In response to the response (off-hook) from the telephone 1a, the voice response device 3b sends out the response ``The balance is...''.

The above is a case where a legitimate depositor uses the computer service, but even if a third party were to know the bankbook number and PIN of the elderly person using the account, they would not be able to receive the computer service fraudulently. , it is impossible to receive the service unless a third party has the opportunity to use the telephone 1a at the elderly person's home.

By the way, in the case of a voice response system such as a scissors as described above, there is no practical problem even if the terminals (telephones) that can be used by the user are limited to terminals that are registered in advance.

In addition, in cases where usable terminals are limited, such as computer systems within the same company or group, by applying the present invention, third party terminals can be used in the same way as when using a private line while using a public line. It is possible to prevent unauthorized use by persons and also obtain economic benefits.

As explained above, according to the present invention, the telephone number of the user or the terminal is registered in advance in the computer system, and when the line is connected in response to a call from the terminal, the terminal After entering the ID from the user, the line is disconnected, and the terminal is called again using the pre-registered phone number based on the entered ID to connect the line, so the public i-line can be used by an unspecified number of people. Even if
Computer fraud can be prevented, and furthermore, it is possible to obtain a mitigating effect.

[Other embodiments of the invention]

It should be noted that the present invention is not limited to the above embodiments.

In the case of a computer system and a general terminal, first input only the terminal number and disconnect the line, then enter the terminal number in advance and use the recorded telephone number to connect the line. It is also possible to connect the . In this way, multiple users can use the same terminal.

Furthermore, the present invention can be implemented only when a predetermined process is requested of the computer system. For example, in the case of the above-mentioned voice response system, if it does not cause direct damage to the user, such as a balance inquiry service, even if a third party uses it illegally, it will be connected as before, and other depositors' accounts will be connected. This can also be done only in cases where there is a risk of harm to the user, such as requesting a transfer.

Moreover, it is a -Y state of computer-based services. It can also be applied to storage and distribution services of voice, text, facsimile, etc., as well as to distribution of drug type information according to user requests.
