Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a password input device for inputting a password in an automatic teller machine (ATM machine) or the like.

[0002]

2. Description of the Related Art In a conventional general ATM machine, at the time of inputting a personal identification number, numbers 0 to 9 delimited by a rectangular frame are sequentially displayed in a horizontal line on a touch panel type liquid crystal screen, and a corresponding numeral portion is displayed. Was pressed by the finger of the input person, and the password was input one digit at a time.

[0003] However, even if it is assumed that the liquid crystal screen is invisible to anyone other than the input person, there is a risk that the input number may be inferred by a third party based on the movement and position of the input person's finger.

[0004] As a solution to this, Japanese Patent Laid-Open Publication No. Hei 3-22555.
In Japanese Unexamined Patent Publication No. 6, the numbers displayed side by side in a row
Rather than arranging in the order of nine, arranging them randomly at each time makes it difficult for a third party to guess.

In Japanese Patent Laid-Open Publication No. Hei 7-320124, a display unit for repeatedly displaying numbers 0 to 9 one by one in order, and when a certain number is displayed, the number is used as a password. By providing a single button that can be entered, it is difficult for third parties to infer.

[0006]

However, in Japanese Unexamined Patent Publication No. Hei 3-225556, there is a problem that the input user is difficult to search for a desired numeral because the digit strings are arranged at random. Then, since numbers are displayed one by one in order, there is a problem that the input user is unnecessarily waited until the desired number is displayed.In each case, the trouble of the input user when inputting the password is reduced. Is increasing.

[0007] An object of the present invention is to prevent a third party from inferring a password from the movement or position of a finger of the input person at the time of inputting the password, and to increase the trouble of the input person. An object of the present invention is to provide a personal identification number input device capable of easily inputting a personal identification number while ensuring high secrecy.

[0008]

According to the present invention, there is provided a personal identification number input device for an automatic teller machine or the like for displaying and inputting a personal identification number on a display unit.
Display control means for displaying a rotating dial and a pointer for aligning the numerals of 0 to 9 on the screen of the display unit as an image and operating the dial to rotate the rotating dial on the screen; And a number determining means for determining the number indicated by the number on the rotating number plate by operating a button.

The display control means randomly associates the numeral on the rotating numeral plate with the pointer each time the password input is started. Further, the display control means displays a digit number display field on the screen of the display unit, and displays the digit determined by the number determination means in the digit number display field.

[0010]

Next, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows an ATM machine to which a password input device according to the present invention is applied. On the upper surface of the main body 1 of the ATM machine, a dial 3 for selecting a password and a button 4 for confirming the password are provided in front of a display section 2 for displaying various information. 1 has a display unit 2
Is provided with a processing unit 5 that performs various processes such as a display control function for controlling the password, a password input control function, and a password determination function.

On the display unit 2, a rotating number plate 6, a digit number display field 7, and a pointer 8 as shown in FIG. 2 are simultaneously displayed as images by the display control function of the processing unit 5. FIG.
FIG. 2 is a system diagram of a display unit 2, a dial 3, a button 4, and a processing unit 5.

The rotating number plate 6 is an image in which a circular plate is equally divided in the circumferential direction by lines, and numerals from 0 to 9 are distributed and displayed in ten divided portions. When the finger is picked and turned, it appears as if the disk is rotating in conjunction with the finger, and furthermore, as shown in FIG. 4, when the dial 3 is turned clockwise, it is turned counterclockwise. When turned in the counterclockwise direction, the direction of rotation and the amount of rotation in the counterclockwise direction are the same.

In the present example, the number-of-digits display field 7 is formed of four quadrangular sections arranged in a horizontal line because the number of digits of the input personal identification number is four. The pointer 8 is a reference for matching any one of the numbers on the rotating number plate 6, and in the case of this example, is an inverted triangle. Rotate the rotating number plate 6 to place an arbitrary number on the pointer 8 and press the button 4 to input the number indicated by the number, and to enter the corresponding digit in the digit number display column 7 as shown in FIG. Is displayed to indicate that the input has been made.

Next, the operation from the start to the end of the input of the personal identification number will be described.

At the start of the input of the personal identification number, the processing section 5 first causes the display section 2 to display a rotating number plate 6, a digit number display field 7, and a pointer 8. At this time, one of the numbers from 0 to 9 on the rotating number plate 6 matches the pointer 8, and the matching number is randomized as shown in FIG. Has become. Thereafter, the processing unit 5 is in a state of waiting for input using the dial 3, the button 4, and the like. In addition, the number displayed on the rotating number plate 6 is always displayed in the same direction even when rotated, so that it is easy for the input person to see.

Then, when the input person turns the dial 3, the processing unit 5 detects the rotation, and as shown in FIG. 4, the rotary numeral plate 6 rotates according to the rotation direction and the rotation amount of the dial 3. To control the display unit 2.

When the input user presses the button 4 when an arbitrary number on the rotating number plate 6 matches the pointer 8, the processing unit 5
Detects that the button 4 has been pressed, acquires the number on the rotating number plate 6 indicated by the pointer 8 as one digit of the password at that time, and indicates that one digit has been entered in the digit number display field 7. Is displayed. In the example of FIG. 5, “4” is input as the first digit of the personal identification number, and a mark is displayed in the frame of the first digit of the digit number display field 7.

When the operation for the number of digits required as the password is repeated in this manner, the input of the password is completed.

[0020]

As described above, according to the present invention, a rotating numeral plate and a pointer are displayed as images on a screen of a display unit.
The input user turns the dial to make the rotating number plate appear to be rotating, and when an arbitrary number on the rotating number plate matches the pointer, the input user presses a button to change the number to a password. Since it is fixed as one digit, the input user's finger only operates one dial and one button,
Since there is no correlation between the position of the finger and the number to be input, the password is not guessed by a third party from the movement or position of the finger of the input person. As a result, it becomes possible to input a password having a higher security level.

Also, since numbers 0 to 9 are arranged in order on the rotating number plate, it is very easy to search for a desired number from among them, and the rotating operation of the dial and the rotating display of the rotating number plate can be performed. Since it is easy to intuitively connect, the operability of the input user is not impaired, and the input user can quickly and easily input the personal identification number.

According to the second aspect of the invention, each time the password input is started, the number on the rotating number plate is made to randomly correspond to the pointer, so the initial state of the rotating number plate is randomly input as the dial rotation amount. The numbers are not correlated, making it more difficult for third parties to make inferences.

According to the third aspect of the present invention, the number of digits display field is displayed on the screen of the display unit, and the determined digits are displayed in the number of digits display field, so that the input number of digits can be easily confirmed. Become.
