Abstract

PURPOSE:To improve a supervisory function for the abnormality of a system by recognizing the time over of a key input interval at a terminal equipment by a host device. CONSTITUTION:A terminal equipment 1 is equipped with an input device 3 and a data display part 7, and the transfer of data between a host device 20 is performed through a communication control part 2. Also, the equipment is equipped with a key input supervisory part 8 and an automatic log-off request generating part 13, and when a key input time value exceeds a prescribed time, it transmits automatically a log-off requesting message to the host. Thereby, the host can recognize the abnormality of the system and after the transmission of an alarm message to the terminal equipment, it cancels a long-on state.

Description

[Detailed Description of the Invention] [Field of Application of the Invention] This invention solves the risk of unauthorized operation by a third party in a terminal device used in a financial institution when the operator of the terminal device connects to a host and leaves his/her seat. It is a useless thing that diminishes sexuality.

[Background of the invention]

In a bank online system in which a host and a terminal are connected online, the method for checking whether there is an abnormality in the response time of the terminal on the host side is conventionally known as Japanese Patent Laid-Open No. 5
As shown in Publication No. 7-209560, the host (master calculation $) fin periodically sends a check signal to each terminal connected to itself, and monitors the response from each terminal to the check signal. Measures were being taken.

This method is certainly effective in terms of monitoring that the terminal equipment is working properly, but the responsiveness of the operator in a certain transaction state (which varies depending on the transaction)
There is no consideration given to the point of monitoring, and this method can usually only be used as a means of confirming the normality of the line or terminal device itself.

Therefore, the usual method for monitoring the response time in the transaction status is for the host to have response time monitoring data in the transaction status of each terminal and check it at the host. This becomes a processing burden on the post side, which provides this service. Furthermore, with this method, it is impossible for the host to monitor the interval between keystrokes of the terminal device. This means that there is a risk that a legitimate operator may leave his/her seat connected (logged on) to the host for some reason, and a third party may perform operations during that time and allow fraudulent transactions.

[Purpose of the invention]

An object of the present invention is to solve the above-mentioned conventional problems, and to provide a terminal device that monitors the operator's keystroke interval and the response time to the host.
By providing a function to automatically notify the host when the time value is abnormally long, this is to prevent unauthorized operations by a third party due to the operator leaving his/her seat, etc.

[Summary of the invention]

The feature of this invention is that, in order to achieve the above-mentioned object, the terminal device is provided with a key human power monitoring section and an automatic logoff request generating section, and when the key human power time value exceeds the set time, the host By automatically sending a logoff request message, the host becomes aware of the abnormality, sends a warning message to the terminal device, and then releases the logon state.

[Embodiments of the invention]

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

FIG. 1 shows a processing block diagram of a terminal device and a host device. The terminal device 1 has an input section d3 and a data display section 7, and exchanges data with the host device 20 via the communication control section 2.

Step 105 If there is data instructing data input monitoring from the input device 3 in the [LOGON OKJ data], the input/output data processing section 5 changes that value to the set value A9. Then, the setting is set to 1B11, and a monitoring start signal is output to the input monitoring section 8.

Step 106: The input monitoring unit 8 starts counting up the cuff/resistance A10 and the counter J312 based on this signal.

Step 107...When data is input from the input device 3, it is transferred to the input/output data processing section 5 via the data input section 4, and at the same time, the presence of the input is reported to the input monitoring section 8. Ru.

Step 108: When the input monitoring section 8 receives this report, it clears the counter A10 and starts current up again from that state.

Step 109...The operator presses the end button after completing the data input.

That data is also Input/output data processing via management department 4 It is passed to the ring part 5.

Step 110...The input/output data processing section 5
As a result, a key manual power prohibition signal is outputted to the data input section 4, and at the same time, a monitoring end signal is outputted to the % input monitoring section 8.

Step 111...The input monitoring section 8 uses this signal to set the counter A10. And stop counting up Kajunta B12.

Step 112...The operator's input data is sent to the host device 20.

Step 113...The host device 20 processes the received data in the terminal data processing unit 22, generates response data, adds data instructing the next input monitoring, and sends the terminal device 20 to the terminal device 20. Send to.

Step 114...The terminal device 1 outputs the answer data to the data display section 7, and also outputs the set value A9. A set value B110 is set, and a monitoring start signal is output to the input monitoring section 8. Further, an input permission signal is outputted to data manual @4.

Step 115... In this way, monitoring of operator inputs begins again.

Next, the process to be performed when the key manual monitoring times out will be explained with reference to FIG.
