Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to, for example, a key input H1ff for keying secret information.

(Prior Art) For example, when performing financial transactions such as withdrawing banknotes using a cash card and automatic banknote deposit/withdrawal device,
The user first inserts his/her cash card into the automatic banknote deposit/withdrawal device. Then, an instruction to input a pre-registered password on the keyboard is displayed on the display screen. The user manually inputs the password according to this instruction, and the input password is displayed as is on the display device. This is necessary for the user to confirm whether or not the password entered using his or her key has been entered correctly.

On the other hand, since the automated cash withdrawal device is installed in a public space such as a customer floor of a bank, there are often other users next to the user. Therefore, when the PIN number, which is confidential information, is displayed on the display screen when the key is manually operated, there is a risk that the PIN number may be known to others.

(Problems to be Solved by the Invention) In order to eliminate such inconveniences, it is conceivable to display, for example, a mark "*" or the like on the display screen corresponding to the number of digits of the password entered manually. With this method, the user knows the number of digits that have been input in the PIN number, but the user himself does not know whether the PIN number he has entered is correct.

This invention was made in consideration of the above circumstances, and its purpose is to allow users to confirm that the secret information they have entered is correctly entered, along with the number of digits, while maintaining secrecy. It is an object of the present invention to provide a key input device in which the present invention is implemented as follows.

[Structure of the Invention] [Means for Solving the Problem 1] The gist of the present invention is that when a key corresponding to information to be input is operated, the input information is not displayed during the key operation period or for a predetermined period of time. is displayed on the display section, but when the key is released or a predetermined time has elapsed, the display of the input information is erased and a predetermined symbol other than the input information is displayed instead. There is a particular thing.

(Function) 1 According to the present invention, input information is displayed on the display section for at least a predetermined period of time when a key is operated, so the user can confirm the information he or she has input, and then the symbol Since the digits are displayed, errors in information input are reduced, and troubles are reduced. In addition, only the digit of input information is displayed, and previously input information is displayed with only the digit as a symbol, so that confidential information will not be leaked to others.

(Example) The present invention will be explained in detail below with reference to illustrated embodiments.

FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention. In the figure, reference number 11 is an automatic banknote deposit/withdrawal device, and inside thereof, an information processing/exchange device 12 such as a CPU, a display device 13, and a keyboard 14 for inputting password information etc. are provided. . Information processing/interchange i! A password information verification unit 15 is provided in the A device 12.

For example, when a user wishes to withdraw a predetermined amount of money from the banknote automatic deposit/withdrawal device 11 having such a configuration, the user inserts the cash card 16, which serves as an information recording medium, in the user's possession. When the information processing/exchange HW 112 detects that the cash card 16 has been correctly inserted into the predetermined position, the information processing/exchange HW 112 sends a second message to the user.
The display shown in Figure (a) is performed on the display device 13.

Following this message, the user inputs his/her password information character by character from the keyboard 14. If the first character of the user's password information is "1", the key "1" is pressed and this "1" is displayed on the display device 13 as shown in FIG. 2(b). This allows the user to confirm his or her key-in information. The information processing/exchange device 12 has a separate surface attached to all the keys on the keyboard 14 that detects the pressed and released states of the keys, and displays the display device 1 while the keys are being pressed.
It also has a function to continue displaying the character corresponding to that key on the screen.

When the user releases his/her finger from the key "1", the information processing/switching device@12 detects this and erases the display of "1" on the display device 13, instead displaying the key "1" as shown in FIG. 2(C). Display the "*" symbol. By displaying this "*" symbol, the user can enter the number of key-in digits by 6'lH, but the key-in information cannot be determined by others. Of course, other symbols or character caps may be used instead of the "*" symbol.

As shown in FIG. 2(C), after the user releases the key "1", a message prompting the user to input the PIN information is displayed, so the user can input the second character "
2" key is pressed. When key “2” is pressed, the second
As shown in figure (d), the second digit PIN information “2” is [*
] symbol. While the key "2" is pressed, the display state shown in FIG. 2(d) is maintained. Therefore, the sooner the user releases his or her finger after Tl1i R, the less the risk of it being read by someone else.Moreover, the first digit character has already been displayed as an ``*'' symbol, and 1 The first and second digits are never read at the same time, providing extremely high level of confidentiality.

By repeating the above operations, all the predetermined digits of password information are entered manually. Through the above operations, the user can confirm which information is pressed each time a key is pressed.

If a character that does not correspond to the key you pressed is displayed, you can invalidate the password information you have entered up to that point. This means that even if the user intends to enter the PIN information correctly, a defective or malfunctioning information input device such as a keyboard, or a user's input error may occur, resulting in discrepancies at the stage of verifying the PIN information after entering the key manually. It is possible to prevent such inconveniences from occurring.

Furthermore, even when multiple characters are input with a single key operation due to key chattering, the number of digits of the input information is always displayed and can be confirmed, so there is no need to perform a collation operation even if there is an input error.

When the user inputs the password information, the input password information is sent to the verification device 15. On the other hand, nine registered passwords, which are registered in advance in the inserted cash card 16, are read and sent to the verification device 15. Both pieces of password information are collated by the collation device 15, and the result is displayed on the display device 13 as necessary. If they match, the process proceeds to the next operation for withdrawal.

In the above embodiment, a verification device is provided in the information processing/exchange device, but as shown in FIG. 3, a verification device 25 is provided in the cash card 16, and a password information record The password information registered in advance in the device 27 may be compared with the password information input from the keyboard 14.

The other configurations and operations are the same as those of the embodiment shown in FIG. 1, and therefore will not be described here.

FIG. 4 shows yet another embodiment.

In the embodiments shown in FIGS. 1 and 3, when verifying PIN information, a PIN information input device, such as a keyboard, is provided on the automatic banknote deposit/withdrawal device, and the PIN information is verified with the cash card inserted. However, the verification of the password information may be performed using only the information recording medium, for example, the cash card shown in FIG. 4.

In FIG. 4, the kit/bush card 36 includes an adjacent phase processing/exchanging device 32, a display device 33, a keyboard 34,
Verification device 36. A password information recording device 37 is provided. In this embodiment, a timer 3 is provided in the information processing/switching device 32.

This is to detect that a predetermined time has elapsed since the key operation No. 4 was performed.

In the embodiment shown in FIG. 4, the user goes to the bank where the transaction is to be made, and in front of the person in charge at the counter, the user 3.
6. Operate the verification key (not shown) on the top. Then, in response to this key operation, the information processing/exchange device 32 sends a message to the display device 3.
3, a command to display the message shown in FIG. 2(a) is output. When the user operates the [1] key in accordance with this message, the display shown in Figure 2(b) is displayed, and at the same time timer 3 is activated.
8 starts timing. The timer 38 is set for a predetermined period of time, e.g.
When the second hand finishes timing, the timer 38 indicates that the information processing/exchange device 3
