Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing the configuration of a computer terminal having a security management function for iconified information according to an embodiment of the present invention.

In the computer terminal of FIG. 1, 11 is an external input unit, which is registered in the card by passing a keyboard 11-1, a mouse 11-2, an ID card, etc. for inputting characters and numbers. The card reader 11-3 for reading the stored information.

An input signal determination unit 12 determines the type of the input signal from the external input unit 11, and controls the signal output destination based on this determination. A security information control unit 13 manages information such as personal identification information in the security information storage unit 14-1 based on a signal from the external input unit 11 received via the input signal unit 12.

Reference numeral 14 denotes a memory, which is composed of the above-mentioned security information storage unit 14-1 and a display information storage unit 14-2 in which various information for displaying on the display unit 17 is stored. .

Reference numeral 15 is a code comparing section, which is an input judging section 1.
The signal from 2 is compared with the password information stored in the security information storage unit, and the result of matching is output to the display control unit.

A display control unit 16 obtains necessary information from the display information storage unit 14-2 based on each input signal and controls the display on the display unit 17. Further, FIG. 2 is a diagram for explaining iconization and its redisplay according to the embodiment of the present invention.

In FIG. 2, an iconification request section 22 which is in the window 21 and requests to iconify the window, a code input window 23 which is displayed when a code input request is made to the user, and Icons 24-1 and 24-2 are shown.

FIG. 3 is a diagram showing an example of the security information storage unit shown in FIG. Reference numeral 31 is a window number registration unit that indicates the correspondence with each window. Further, a security registration unit 32 indicating whether or not security registration is performed for each window and a personal identification number registration unit 33 in which personal identification information is registered are shown. Then, in the security registration unit 32, “0” is not registered,
“1” indicates that there is security, and “2” indicates that there is no security.

First, the registration of security information will be described. A user (not shown) performing a certain work using the computer terminal interrupts the current work, and the display unit 1
When the window 21 displayed in 7 is temporarily iconized, the user operates the mouse 11-1 to select the iconification requesting section 22 in the window 21.
At this time, the input information determination unit 12 determines that the signal from the mouse 11-2 is a request signal for iconifying the window 21 displayed on the display unit 21, and the determination result is the security information control unit. Send to 13. When the security information control 13 receives the iconification request signal, the display control unit 16 prompts the user to enter the code input window 2
Notify to display 3. As a result, the display control unit 16
Reads out the information of the corresponding code input window 23 from the display information storage unit 14-2 and displays the code input window 23 on the display unit 21.

Here, the user inputs a code consisting of a combination of numbers and alphabets using the keyboard 11-1. In addition, when it is not necessary to perform security registration when converting to an icon, a normal iconizing process is performed by selecting an execution key (not shown) on the keyboard 11-1 without entering a code in the window 23. That is, it will be displayed as an icon that can be freely displayed again.

The input signal judging section 12 judges this every time the user inputs a code, and if it is a request signal for selecting another function, the iconification process is stopped and the display control section 16 is executed.
On the other hand, the display of the information that the user was working until immediately before is continued.

However, when a numeral or alphabet is input, the input signal determination unit 12 determines that a code is input and notifies the display control unit 16 of this. Then, when the display control unit 16 receives the notification from the input signal determination unit 12, the display information storage unit 14-2 displays a symbol such as "☆" in the corresponding portion of the window 23 in correspondence with the input digit number. Read from and display.

At this time, the input signal determination unit 12 also notifies the security information control unit 13 of the above-mentioned character or alphabet code, and the security information control unit 13 sends the security information storage unit 14-1 to the security information control unit 13-1 each time it is notified. After registering and completing the input of the required number of digits,
This is notified to the display control unit 16. When the display control unit 16 receives this notification, it performs a display (not shown) for confirming the input completion to the user, and if confirmed, it reads the icon information from the display information storage unit 14-2, and the window 21 Icon display (24-in FIG. 2
1 or 24-2).

An outline of the security information storage unit 14-1 is shown in FIG. 3, in which the security registration unit 32 and the code registration unit 3 indicating the presence or absence of security registration are shown.
There are three. In the window number registration unit 31, windows are numbered and registered in the order in which they are made into icons, and the presence / absence of security and personal identification information are registered for each window number. Here, the security registration unit 32 indicates the security status of the iconified window, 0 indicates unregistered, 1 indicates security, and 2 indicates no security. The personal identification information registration unit 33 is represented by 0 when not registered and is represented by 9 when there is no security. When security is registered, the code entered by the user is registered.

Next, the case where the iconified information is expanded on the display unit 17 again will be described. In this case, the user has a keyboard 11-1 or a mouse 11-
2 is operated to request display of an icon for redisplaying information, for example, the icon 24-1. At this time, as in the above, the input signal determination unit 12 determines that the content of the signal is a redisplay request, and this signal, that is, the redisplay request signal and the file number (here, number 1) is sent to the code comparison unit 15. send. The code comparison unit 15 refers to the security registration unit 32 in the security information storage unit 14-1 and confirms whether the window number 1 is saved in security. In this case, the information in the security registration unit 32 is "1". Therefore, it is determined that there is security, and the display control unit 16 is notified that the display of the code input window 23 is prompted. Display control unit 1 that received this notification
Reference numeral 6 reads the information in the code input window 23 from the display information storage unit 14-2 and displays it on the display unit 17.
When the code input window 23 is displayed, the user inputs the code using the keyboard 11-1.
Also at this time, similarly to the above, when a key other than the code input target such as a character or a number is pressed, the icon restoration process is stopped.

Here, when the code is correctly input, the display control unit 16 displays a symbol such as "*" at the relevant portion of the window 23 in correspondence with the input digit number.
The data is read from 4-2 and displayed. The code is sent from the input judging unit 12 to the code comparing unit 15, and the code comparing unit 15 compares the code of the file number 1 with the personal identification information registering unit 33. Since “0,0,1,2,3” is registered in the password information registration section 33, if the user inputs “0,0,1,2,3”, the code comparison section 15 will match. It is determined that the result of this match is the display control unit 16
Sent to Then, the display control unit 16 receives this notification, reads the information corresponding to the icon 24-1 from the display information storage unit 14-2, and displays it on the display unit 17. If there is an error in the user's code input, the code input window 23 is displayed again, and the user is instructed to re-input. If the user repeatedly makes an input error, for example, if the user makes an error three times in a row, the user may not accept any further input.

The security of the iconified window is maintained as described above. Next, another embodiment will be described. In the above-described embodiment, when the window is redisplayed, the user is prompted to input the personal identification information every time the corresponding icon is selected, and when the input personal identification information matches the registered one, Although it is displayed as a window, input of personal identification information may be prompted in advance. In this case, the user inputs the personal identification information, and only the icon corresponding to the window that matches the input personal identification information can be re-displayed as a window, and the display method different from other icons is used to inform the user. Notice.

More specifically, when the computer terminal is powered on, a plurality of icons 24-is displayed on the display unit 17.
A code input window 23 is displayed at the same time as 1, 24-2. At this time, the icon corresponding to the window that is not restricted to the user and the icon that can be displayed in the window when the password information is input are displayed separately. For example, red may be used for those requiring illegal input due to personal identification, and blue may be used for those having no limitation on the user.

When the user uses the icon which only the user can display in the window, the mouse 11-2
Use to enter the code input window 23 into a state in which personal identification information can be input, and then enter the code input window 23
Enter the password information for. When the personal identification code is input, it is determined in the code comparison unit 15 whether the personal identification information input to the security information registration unit 14-1 is registered, and if there is a corresponding one, the fact is displayed. When the notification is sent to the control unit 16 and the notification is received, the display control unit 16 changes the display color to, for example, green in order to indicate that the display of the corresponding icon (for example, 24-2) can be used. In this case, a plurality of windows corresponding to the same password information may exist, or the password information may be set for each window. The icon 24-2 displayed in green is displayed as the window 21 by selecting it with the mouse 11-2. As described above, in other embodiments, the icon corresponding to the window in which the password information needs to be input is displayed from the beginning on the display unit 17, but immediately after the power of the computer is turned on, it is restricted to the user. It is also possible to display only the icon corresponding to the non-existing window, and after the password information is input by the user, display the icon corresponding to the window that matches this password information.

Further, the input of personal identification information is performed by the keyboard 11-
Rather than using 1, the card reader 11-3 is provided,
For example, an employee ID card owned by the user may be used. In this case, the reliability of the confidentiality is further improved because the window cannot be redisplayed without the card as compared with the case of using the keyboard.

[0032]

As described above, according to the present invention, when redisplaying an iconified window, it is possible to set such that redisplay cannot be performed unless the personal identification information is selectively input. It becomes impossible for a third party to refer to it freely, and the confidentiality of such information can be easily managed.
