Description

  The present invention relates to an automatic teller machine that is installed in a financial institution or the like and is excellent in security when inputting a password. The present invention relates to an automatic teller machine with extremely high security that contributes to convenience.

As an automatic teller machine for inputting a password used for identity verification or the like, for example, an ATM installed in a store of a financial institution is known.
In this ATM, when entering a password, what is mainly selected and pressed a number displayed on a display unit such as a touch panel is the mainstream, the shape and color of the pressed key is visually changed, The user can operate the screen while confirming the pressed password.

However, as for the PIN number input key in the automatic teller machine, since the arrangement is generally fixed, if the ATM arrangement pattern is known, the key on the screen cannot be seen when the cash is withdrawn. However, there is a problem that it is possible to know which key is pressed by the position and movement of the arm and elbow, and important information such as a password is leaked to others. In recent years, ATMs have been placed in public spaces such as airports and stations from financial institutions, and as a result, further security problems have arisen.
Japanese Patent Laid-Open No. 10-105781 For this reason, Japanese Patent Application Laid-Open No. 17-135224 proposes an apparatus that can change the arrangement contents of numeric keys at the time of input of a personal identification number to enable input. Patent Document 2 proposes a device that changes the arrangement contents of the numeric keys every time an input is made.

However, today, with the aging of the population, there is a demand for a display that is easy to see for the elderly, and the display is enlarged and the display screen is tilted to make it easier to see. Therefore, there is a high possibility that peeping from behind is easy, and there is a problem that even if the means as described in Patent Documents 1 and 2 are adopted, processing of the entire input becomes easy to see.
The present invention has been made in view of the above circumstances, and relates to an automatic teller machine that is excellent in security when inputting a password. More specifically, the present invention can avoid damages due to the exception of the back as much as possible. An object of the present invention is to provide an automatic teller machine with extremely high security that contributes to the convenience of elderly people and the like.

The present invention comprises an automatic teller machine comprising a touch panel and a display, wherein an input key is displayed on the touch panel and a password can be input by pressing the input key. Provided is an automatic teller machine characterized by displaying an input key not to be displayed and a guidance display indicating a key arrangement of the input key.
Further, the cash dispenser displays the input key and / or the guidance display so that the display can be moved to an arbitrary position.
Furthermore, an automatic teller machine in which the display is inclined is provided.

In an information terminal placed in a public space such as an automatic teller machine, the user refers to a guidance display when inputting information such as a personal identification number that has security problems when viewed by others. Since the actual password can be input with a blank key that does not display the arrangement, even if the position pressed by the user can be seen from behind, it is possible to prevent a problem that the input password is known to others.
In addition, the present invention can display the input key and / or the guidance display displayed on the display so as to be movable to an arbitrary position at the time of password input, so that only the guidance display is moved in front of the user's eyes. You can easily perform input operations using the input keys while looking at the guidance, so even if you can see it from behind, you will not know what the secret is, and you can also hide the guidance display from behind the view. Further improvement can be achieved.

  And according to the present invention, since it can be suitably adopted as a screen to be displayed on an inclined display, it can be suitably adopted for an ATM having an inclined display, and security problems due to peeping can be avoided. Excellent convenience can be imparted by the synergistic effect of tilt and security. In particular, by moving the input keys and the guidance display according to the convenience of the user, at least one of the keys can be hidden, making it difficult to easily understand the password even when viewed from behind. .

  Hereinafter, although the automatic transaction apparatus of this invention is demonstrated concretely with reference to drawings, this invention is not restrict | limited to the following Example.

  FIG. 1 is a block diagram showing a device configuration of an automatic teller machine 100 according to one embodiment of the present invention. In the figure, 110 is a main processing unit including a central processing unit, 120 is a storage unit, 121 is a main program unit that stores a main program in the storage unit 120, and 122 is a unit that converts information related to a password in the storage unit 120. The code number conversion unit 130, 130 is a touch panel that accepts user operations, and 140 is a display that displays according to instructions from the main calculation unit 110. The touch panel 130 is disposed on the display 140, and when the user presses a key displayed on the display 140, the touch panel 130 is configured to detect corresponding position information.

FIG. 2 is a flowchart of information processing in the automatic teller machine shown in FIG. 1, and describes a password input process of the automatic teller machine 100 according to the present invention.
Here, the processing of the automatic teller machine according to the present embodiment will be described using the reference numerals in FIG. 1 and the flowchart in FIG. 2. First, the user places a cash card or the like at a predetermined position of the automatic teller machine 100. A predetermined card is inserted, and what kind of processing is desired is selected according to the content displayed on the display 140. The encryption process of the present invention corresponds to a specific process selected from these processes, and is used at the time of a process requiring password input such as balance inquiry / withdrawal. Therefore, when it is not necessary to input a personal identification number as in the case of payment, the processing is started there and the processing of the present invention is not performed.

In the present invention, the user is instructed to start processing when encryption input such as transfer / withdrawal is required. (S-0).
In response to this instruction, the main calculation unit 110 extracts the personal identification number information stored in the main program unit 121 of the storage unit 120 (S-1).

  Then, based on the extracted information, the personal identification number conversion unit 122 converts the personal identification key in accordance with a predetermined method and outputs it on the display 140. Here, the personal identification number conversion unit 122 records personal identification number information that can be extracted from the main program unit 121 in the personal identification number information storage unit 202 of the personal identification number conversion table as shown in FIG. 3 (S-2). ).

  In the personal identification number conversion table of FIG. 3, the personal identification key 1 position information and the personal identification key 2 position information indicate what kind of personal identification key is pressed when the personal identification key 1 is pressed. Key 1 corresponds to an input key, and PIN key 2 corresponds to a guidance display. The personal identification number information storage unit 202 indicates a number that is actually pressed. For example, when the position “K10” of the personal identification key 1 is pressed, the actual personal identification number is “0”. Although defined, such a definition is appropriately selected according to usage settings and is not particularly limited.

When processing by the conversion unit is performed, an input key is displayed on the display. The screen at this time is shown in FIG. That is, FIG. 4A shows an initial state of the personal identification number input screen 50, which is displayed at two locations of the personal identification key 1 (51) and the personal identification key 2 (52) on one display (S- 3).
In the secret key 1 (51), K1 to K10 key information is assigned to each numeric key. Also, the code key 2 (52) is assigned numbers K11 to K20 to the respective numeric keys, and the correspondence between the code key 1 (51) and the code key 2 (52) is a code number conversion as shown in FIG. Managed by the conversion table of the unit 122.

  In this embodiment, the secret key 1 (51) is located in the center, and the numbers are displayed in a blank so that the arrangement is not known. The personal identification key 2 (52) is arranged at the bottom of the screen, and the number of the input arrangement of the personal identification key 1 is displayed. That is, K1 to K10 indicate keys corresponding to K11 to K20 in the table shown in FIG. 3, and the display of K1 to 10 in FIG. 4 is expressed as a non-display blank key.

Therefore, when the user inputs the personal identification number, as shown in FIG. 4B, the personal identification number displayed on the personal identification key 2 (guidance display) (52) is confirmed as the guidance display while confirming the personal identification number. Each key of the touch panel 130 of key 1 (input key) (51) is pressed. Nothing is actually displayed on the password key 1 and only the key portion is output, but the portion actually corresponding to the password key 1 is pressed while referring to the password key 2 (52). This makes it possible to perform password input. Therefore, even if the input is looked into from behind, the input portion is blank, so it is not possible to know what key is pressed by just looking.
The personal identification key 2 does not have a function as a key, and is configured to accept only the personal identification key 1 (51) (S-4).

The main operation unit 110 performs a procedure for the pressed key in accordance with the main program 121 for the input password. This is compared with the contents of the personal identification key 1 position information 200, personal identification key 2 position information 201, and personal identification number information storage unit 202 stored in the personal identification number conversion unit 122, and shows what actual number is pressed as the personal identification number. Determine (S-5).
When such operations are repeated and a predetermined number is set as the password, for example, the predetermined number is 4 digits, the main calculation unit 110 determines each of the 4 digits, and if the 4-digit password is not input, S Returning to -4, the next password is retaken (S-6).

  According to the first embodiment, in a highly public automatic teller machine or the like, when there is a security problem such that a personal identification number can be seen by a third party, the number pushed from behind the user can be seen. Can be prevented. When viewed from the back, the number is not displayed on the input key, so it is not known which number is being pressed. It is effective in improving security while maintaining ease of pressing keys.

  FIG. 5 is a block diagram showing a device configuration of the automatic teller machine according to the second embodiment. Hereinafter, in the description of the second embodiment, the same portions as those in the first embodiment are denoted by the same reference numerals, and Description is omitted.

  In the second embodiment, in addition to the information input device of the first embodiment, a display position management unit 123 of the password 2 (52) is further added to the storage unit 120. The display position management unit 123 can change the position of the personal identification key 2 (52), which is a guidance display, from the touch panel 130 to be movable, and depending on which position on the display 140 the user displays the personal identification key 2 The position information of the main calculation unit 110 is calculated and displayed on the display 140.

FIG. 6 is a flowchart of the information processing in FIG. 5, and the information processing operation of the second embodiment is basically the same as that of the first embodiment, but in the step (S-7) added in the second embodiment, The processing of the secret key 2 display position management unit 123 is further performed.
That is, after the information related to the display of the personal identification number is converted by the personal identification number conversion unit 122 (S-2), the position on the display for displaying the information is calculated based on the positional information of the main arithmetic unit. When done, it is displayed in two places on the display (S-3). The display on this screen is shown in FIG. As shown in FIG. 7A, the window (52-b) of the personal identification key 2 on the personal identification number input screen 50 is displayed as a separate window at the position (Xa, Ya) calculated in the above steps.

  Then, when the user inputs the personal identification number, the user presses the portion corresponding to each key of the touch panel 130 of the personal identification key 1 (51) while confirming the numerical arrangement displayed on the personal identification key 2 (52). (S-4), the user can move the window (52-b) of the personal identification key 2 by an operation such as dragging. When moved in this way, the operation returns to S-3, the display position of the window (52-b) of the secret key 2 is calculated at the dragged position, and dragged as shown in FIG. 7 (b). The display is performed again at the position (S-7).

The main operation unit 110 performs a procedure for the pressed key in accordance with the main program 121 for the input password. This is compared with the contents of the personal identification key 1 position information 200, personal identification key 2 position information 201, and personal identification number information storage unit 202 stored in the personal identification number conversion unit 122, and shows what actual number is pressed as the personal identification number. Determine (S-5).
When such operations are repeated and a predetermined number is set as the password, for example, the predetermined number is 4 digits, the main calculation unit 110 determines each of the 4 digits, and if the 4-digit password is not input, S Returning to -4, the next password is retaken (S-6).

  In the second embodiment, since the display position of the key indicating the numerical arrangement can be freely changed, it can be displayed at a position easy for the user to see. In addition, since the key indicating the numerical arrangement can be displayed at a position where the user cannot look into from behind, the security is improved as compared with the first embodiment.

The present invention is not limited to the illustrated embodiment, and various modifications can be made. Examples of such modifications include the following.
In the embodiment, the arrangement of the numeric keys to be displayed is as shown in the figure, but the present invention is not limited to this arrangement, and the numeric keys may be displayed in a random arrangement. The password can be changed as appropriate not only with numbers but also with symbols, characters, and other various displays.
Further, the size of the numeric keys displayed on the display may be freely changed such as enlargement or reduction, and the display position of the numeric keys may be changed any number of times during the input.

  Further, in the embodiment, the input password is four digits, but the present invention is not limited to this. Furthermore, the password can be displayed so that the order of password input can be visually understood, as in a normal ATM. For example, when inputting a 4-digit number, “XXXXX” and four “ It is also possible to display it with “○” and input it while recognizing where the part represented by “●” is visually so that it becomes “● ○○○” when one is input.

  Furthermore, the present invention can be suitably used not only as a flat display but also as a screen to be displayed on a tilted display, and in particular, can be suitably used for a tilted display that is easy to see for the elderly. And since the problem of security by peeping can be avoided, excellent convenience can be given by the synergistic effect of these inclination and security. By moving the input key or the guidance display according to the convenience of the user, at least one of the keys can be hidden, so that it is possible to avoid understanding the password easily even when viewed from behind.
