Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a user input recognition device provided in an automatic transaction device for performing a predetermined transaction and recognizing a predetermined user input based on a user operation.
[0002]
[Prior art]
Conventionally, an automatic transaction device that automatically performs a predetermined transaction with a user has been practically used. In the automatic transaction apparatus, an input of a personal identification number or the like is performed based on a user operation on an input mechanism such as a touch panel or a numeric keypad. The automatic transaction device realizes a transaction desired by the user based on the input. For example, an ATM (Automatic Teller Machine) of a financial institution is provided with a key input device such as a numeric keypad for inputting a personal identification number and a transaction amount. The user can realize a desired financial transaction by performing a key input.

[0004]
[Problems to be solved by the invention]
However, when the numeric keypad provided on the ATM is operated, the movement of the user's arm or finger may be peeped from behind, and the password or the like may be grasped. If the password is known to the malicious criminal, there is a possibility that the administrator and the user of the ATM will suffer enormous damage. In addition, even a simple transaction amount or the like is something that a normal user wants to keep secret.
[0005]
Of course, it is also conceivable to use an ATM configuration that is difficult to see from behind, or to provide each ATM in a private room isolated from the public. However, if such a method is used, the convenience of the ATM or the ATM corner is hindered, and a large cost is incurred for the ATM installer or manager.
[0006]
The above-described problem is not limited to the ATM but is a problem common to the case where a user input recognition device provided in an automatic transaction device and inputting a predetermined user input based on a user operation is used.
[0007]
The present invention has been made to solve the above-described problem, and has as its object to improve the confidentiality of user input in a user input recognition device provided in an automatic transaction device.
[0008]
[Means for Solving the Problems and Their Functions and Effects]
In order to solve at least a part of the problems described above, the present invention employs the following configuration.
A user input recognition device according to the present invention is a user input recognition device provided in an automatic transaction device for inputting a predetermined user input based on a user operation, wherein an input mechanism for the user to operate and the operation A recognition unit that recognizes the user input on the basis of the input mechanism, and a prohibition unit that prohibits the recognition unit based on the operation under a predetermined condition even when the input mechanism is operated. Is the gist.
[0009]
By doing so, the user input of the automated teller machine can be kept secret from a third party. This is because a third party must distinguish between operations performed by the user that are prohibited by the prohibited unit and those that are not. The user of the automatic transaction apparatus can conceal the specific contents of the transaction such as the personal identification number by exchanging the fake operation of deceiving or confusing the third party with the original operation. Also, due to such confidentiality, the degree of freedom of the configuration of the automatic transaction apparatus itself and its installation location is increased. This is because the operation of the user can be seen by a third party.
[0010]
In addition, as the automatic transaction device, various devices such as a bank ATM, a ticket vending machine such as a railway, a vending machine such as a beverage, and a ticket issuing machine can be applied.
[0011]
The input mechanism includes various means for mechanically, electrically, audioly, and optically acquiring user input.
Switches and sensors, and a liquid crystal touch panel can be used.
[0012]
The recognition unit may receive a signal such as electricity from the input mechanism, or may transmit a user operation by a physical or mechanical mechanism such as a hydraulic cable.
[0013]
The prohibition unit may determine the prohibition condition by software. Further, transmission of an electric signal may be physically or electrically interrupted. For example, a logic circuit or the like according to the prohibition condition may be used. Further, transmission such as a clutch or the like may be inhibited by a mechanical mechanism.
[0014]
Note that the user input recognition device may include a setting unit that stores the form and type of fake operation. Here, it is desirable that the storage be performed for each user. For example, when a numeric keypad is used, the depression of a key may be ignored for a set predetermined numerical value or numerical value sequence.
[0015]
The user input recognition device of the present invention further includes an output unit that outputs a visual or audible output that can be perceived by a user based on the operation, and the output unit outputs the output even when the prohibition is performed. May be performed.
[0016]
This makes it difficult for a third party to distinguish between the original operation and the fake operation. This is because the visual or audible output is performed regardless of whether the operation is a fake operation. Note that the visual or auditory output can use display by a liquid crystal panel or a lamp, generation of an electronic sound, or the like.
[0017]
In the user input recognition device of the present invention, an instruction mechanism for inputting a predetermined dummy instruction may be provided, and the prohibition unit may perform the prohibition on the predetermined operation associated with the dummy instruction.
[0018]
In this manner, the fake operation can be used at a timing desired by the user.
[0019]
For example, a user input recognition device in which a password is input using a ten key and an invalid key may be used. When a numeric key on the numeric keypad is pressed simultaneously with an invalid key, the function of the prohibiting unit is ignored. Simultaneous pressing with an invalid key is a fake operation. By appropriately inserting the fake operation into the original operation, it is possible to prevent a third party from grasping the password by peeping at the operation.
[0020]
For example, the operation at the same time as the dummy instruction may be ignored, the operation immediately after the dummy instruction may be ignored, or the operation immediately before the dummy instruction may be invalidated. . When the operation immediately after the dummy instruction is ignored, the dummy instruction may have a predetermined expiration date.
[0021]
Further, the use of the dummy instruction may be forced by the user. This is for security reasons. For example, the input may be regarded as valid only when the dummy instruction is used in a predetermined number of times or more in a predetermined manner in inputting the password. Here, the predetermined mode may be determined according to the security level associated with the user.
[0022]
In the user input recognition device of the present invention, the instruction mechanism may be a key that can be pressed, and the prohibition unit may prohibit the operation at the same time as the key is pressed.
[0023]
For example, a numeric string representing a password or the like may be input by a user input recognition device having a numeric keypad having numeric keys of 0 to 9 and a key for inputting a dummy instruction.
[0024]
The pointing mechanism may use various switches, sensors, keys, and a liquid crystal touch panel that mechanically, electrically, audibly, and optically acquire user input. The instruction mechanism may have the same or similar configuration as the input mechanism, or may have a configuration that is significantly different from the input mechanism. The pointing mechanism may be provided near the input mechanism, or may be provided physically separated from the input mechanism.
[0025]
In the user input recognition device of the present invention, the input mechanism may include a key that can be pressed, and the recognition unit may perform the recognition based on the pressing.
[0026]
In the user input recognition device of the present invention, the key has two or more pressing modes, and the prohibiting unit prohibits the recognition based on the pressing when the pressing is performed in at least one of the modes. It may be.
[0027]
This makes it difficult for a third party to distinguish between the original operation and the fake operation. For example, the pressing mode can be distinguished by a pressing amount such as a half pressing / full pressing, a pressing force, a pressing portion, a pressing time, or a combination thereof.
[0028]
In the above-described case, a circuit configuration or the like in which a signal is not sent to the recognition unit when the button is pressed in the mode related to the fake operation may correspond to the prohibition unit. In such a case, the recognition unit only needs to recognize all signals detected from the key as being related to a non-fake operation.
[0029]
The present invention can be configured in various modes such as a control method of a user input recognition device and a user input recognition method, in addition to a mode as a user input recognition device. Further, these methods may be configured as a computer program itself realized by a computer or a signal which can be regarded as the same. Furthermore, you may comprise as a recording medium which recorded these computer programs.
[0030]
Examples of the storage medium include a flexible disk, a CD-ROM, a magneto-optical disk, an IC card, a ROM cartridge, a punched card, a printed matter on which a code such as a barcode is printed, and an internal storage device of a computer (a memory such as a RAM or a ROM). And various computer readable media such as external storage devices).
[0031]

B. Functional block configuration:
C. processing:
D. Double key:
E. FIG. Circuit configuration:
F. Other variations:
[0032]
A. System configuration :
FIG. 1 is an explanatory diagram illustrating a schematic configuration of an automatic transaction apparatus 100 as an embodiment. The automatic transaction apparatus 100 as an ATM is an apparatus that performs transactions such as cash deposit / withdrawal and transfer in accordance with a user operation. The automatic transaction apparatus 100 has a function of performing a predetermined transaction with the user based on the operation of the operation unit 200 by the user. The user can perform a desired transaction by selecting a transaction subject, designating a transaction amount, and inputting a password through the operation unit 200.
[0033]
In the embodiment, the description will be made assuming that the personal identification number is a four-digit number string, but the present invention is not limited to such a case. Further, in the embodiment, description will be made mainly on the case of inputting a password, but the same applies to the case of inputting a transaction amount.
[0034]
As shown by a broken line in the figure, the automatic transaction apparatus 100 includes various units used for transactions.
The card handling unit 101 reads information recorded on various magnetic stripe cards used in financial institutions such as so-called cash cards. In these cards, a financial institution number, a customer account number, and the like are recorded in a predetermined format, and this information is used for specifying an account to be traded, authenticating the customer, and the like. The passbook handling unit 102 reads information recorded on a magnetic stripe card of the passbook, and prints a deposit / withdrawal record on the passbook.
[0035]
The transfer of the bill with the customer is performed by the bill handling unit 103. The bill handling unit 103 discriminates the bill inserted by the customer when depositing the bill, classifies the bill by denomination, and stores it. At the time of withdrawal, a banknote of the amount specified by the customer is paid out and delivered to the customer through the cash slot.
[0036]
The operation unit 200 has an interface for displaying information for a transaction and an interface for receiving a customer operation. FIG. 1 also shows an enlarged view of the operation unit 200. The operation unit 200 has a key mechanism 210, a sound mechanism 230, and a display mechanism 250.
[0037]
The key mechanism 210 has nine numeric keys associated with the numbers 0 to 9 and an invalid key 220. For example, in FIG. 1, the numeric key associated with the numeral 1 is the numeric key 260. The user inputs a four-digit password by sequentially pressing numeric keys associated with the respective numbers. However, pressing a numeric key functions effectively only when the invalid key 220 is not pressed simultaneously.
[0038]
Instead of the key mechanism 210, various switches and sensors for mechanically, voicely, electrically, and optically acquiring user operations, a liquid crystal touch panel, and the like may be used.
[0039]
The sound mechanism 230 is a mechanism that emits a beep sound. The sound mechanism 230 includes a speaker, an electronic sound generation circuit, and the like. The electronic sound is emitted in response to the pressing of a numeric key of the key mechanism 210. Note that the electronic sound is also emitted when the numeric key is pressed simultaneously with the invalid key 220.
[0040]
The display mechanism 250 can be configured using a liquid crystal display mechanism. The display mechanism 250 has a function of displaying an asterisk “*”. The displayed asterisk 240 or the like is increased by one each time a numeric key is pressed. The increase of the asterisk 240 or the like is also performed when the numeric key is pressed simultaneously with the invalid key 220.
[0041]
In the present embodiment, the operation unit 200 is configured by a combination of the display mechanism 250, the key mechanism 210, and the like, but is not limited to such a case. The display mechanism 250 and the key mechanism 210 may be integrally configured by a liquid crystal touch panel. Further, the sound mechanism 230 may be separate from the operation unit 200.
[0042]
The operation of each unit is controlled by the control unit 300. The control unit 300 is configured as a microcomputer having a CPU, a memory, and a hard disk therein. The control unit 300 is connected to the communication unit 104. The control unit 300 communicates with a server (not shown) connected via a network by the communication unit 104. The control unit 300 implements a transaction according to a user operation while using the communication. For example, the communication number is verified using the communication.
[0043]
B. Functional block configuration:
FIG. 2 is an explanatory diagram showing a functional block configuration of the automatic transaction apparatus 100. In the present embodiment, the functional blocks of the automatic transaction apparatus 100 are constructed as software by recording a program for realizing each function in the memory of the control unit 300. In addition, all or some of the functional blocks of the automatic transaction apparatus 100 can be constructed by hardware.
[0044]
The control unit 310 controls each functional block.
[0045]
The card control unit 301 controls the card handling unit 101. Similarly, the passbook control unit 302, the deposit / withdrawal control unit 303, and the communication unit 304 control the passbook handling unit 102, the bill handling unit 103, and the communication unit 104, respectively.
[0046]
The input unit 311 receives a signal related to a user's key input from the key mechanism 210, and detects the user's pressing of the numeric key or the invalid key 220.
[0047]
The audio unit 312 causes the audio mechanism 230 to generate an electronic sound. The display unit 313 causes the display mechanism 250 to perform display. The control unit 310 causes the electronic sound to be generated and the display to be performed in response to the detection of the user pressing the numeric key on the input unit 311.
[0048]
The storage unit 314 sequentially stores the four-digit numeric password in response to a user's key press on the input unit 311. After all four-digit numerical values are input, control unit 310 verifies the password. The verification is performed using the communication via the communication unit 304.
[0049]
C. processing:
FIG. 3 is a flowchart showing the numerical value string input processing. With this processing, a four-digit numerical password is input.
[0050]
In step Sa0, the input unit 311 detects that a numeric key has been pressed.
[0051]
In step Sa1, it is checked whether or not the pressing is simultaneous pressing with the invalid key 220. The control unit 310 can know via the input unit 311 whether or not simultaneous depression with the invalid key 220 is performed.
[0052]
In step Sa2, a process of adding the content stored in the storage unit 314 is performed. If simultaneous depression is detected in step Sa1, the storage addition in step Sa2 is not performed.
[0053]
In step Sa3, the display content of the display mechanism 250 is changed. Specifically, one additional asterisk “*” is displayed. The addition is performed irrespective of whether or not the user presses the key simultaneously with the invalid key 220. The total number of asterisks 240 displayed on the display mechanism 250 indicates the total number of depressions of the numeric keys.
[0054]
In step Sa4, the audio unit 312 generates an electronic sound. The generation of the electronic sound is also performed regardless of whether the user presses the key simultaneously with the invalid key 220.
[0055]
In step Sa5, it is checked whether the storage of the four numerical values in the storage unit 314 is completed. If completed, in step Sa6, the control unit 310 verifies the password consisting of the four numerical values. If the input of the four numerical values is not completed, the process returns to the step Sa0 to acquire the next input of the numeric keys.
[0056]
FIG. 4 is an explanatory diagram showing a specific example of the numeric string input processing. FIG. 4 shows the presence / absence of voice / display output and the storage status of the storage unit 314 at each timing of pressing the numeric keys in steps Sb1 to Sb5.
[0057]
Regarding step Sb1 in FIG. 4, first, it is detected in step Sa0 in FIG. 3 that the numeric key 260 (see FIG. 1) corresponding to the numerical value 1 is depressed. Subsequently, it is determined in step Sa1 that pressing the numeric key is not simultaneous pressing with the invalid key 220. Since the input of the numerical value 1 is the first input, additional storage of the numerical value 1 is performed in step Sa2 in the storage unit 314 in which no numerical value is stored. Further, the display content of the display mechanism 250 is changed from a state where nothing is displayed to a state where one “*” is displayed in step Sa3. Generation of an electronic sound is also performed in step Sa4. At the stage of step Sb1 in FIG. 4, since only one numerical value has been input, the process returns to step Sa0 based on the determination in step Sa5.
[0058]
In step Sb2 of FIG. 4, the numeric key corresponding to the numerical value 2 is pressed. Thus, the display content of the display mechanism 250 becomes “**”, and the storage content of the storage unit 314 becomes “12”. Also, the electronic sound of the sound mechanism 230 is generated again. The same applies to the input of the numerical value 3 in step Sb3, and the display content is “***” and the storage content of the storage unit 314 is “123”.
[0059]
In step Sb4 of FIG. 4, the numerical key corresponding to the numerical value 4 and the invalid key 220 are simultaneously pressed. In this case, since it is detected in step Sa1 in FIG. 3 that the pressing of the numeric key is the simultaneous pressing with the invalid key 220, the storage addition processing in step Sa2 is not performed. Therefore, the storage content of the storage unit 314 is maintained at “123”. However, the display content of the display mechanism 250 is changed to “****” in step Sa3, and an electronic sound is also generated in step Sa4.
[0060]
Finally, in step Sb5 of FIG. 4, the input of the numerical value 5 is performed not by pressing the invalid key 220 at the same time but by itself. As a result, the display content becomes “****” and the storage content becomes “1235”. Since it is known in step Sa5 that the storage unit 314 is in a state of storing a numerical sequence of four numerical values, the control unit 310 verifies the password “1235” in step Sa6.
[0061]
According to the automatic transaction apparatus 100 described above, even when the operation of the user is seen by a third party, the password input by the operation can be kept secret from the third party. When the invalid key 220 is not pressed at all, it functions as a general numeric keypad.
[0062]
Note that the invalid key 220 may be pressed alone instead of being pressed simultaneously with the numeric keys. For example, when the invalidation key 220 is pressed alone, the storage addition process in step Sa2 is not performed, but only the display process in step Sa3 and the generation of the electronic sound in step Sa4 may be performed.
[0063]
Further, in the embodiment, the pressing of the numeric key while the invalid key 220 is pressed is invalidated, but the pressing of the numeric key immediately after or immediately before the pressing of the invalid key 220 may be invalidated. .
[0064]
When the pressing of the numeric key immediately before the pressing of the invalid key 220 becomes invalid, in the example shown in FIG. 4, the key of the numerical value 4 is pressed alone in step Sb4, and after the pressing, between steps Sb4 and Sb5 When the invalid key 220 is pressed, a numerical value string “1235” is input.
[0065]
When the pressing of the numeric key immediately after the pressing of the invalid key 220 becomes invalid, in the example shown in FIG. 4, the key of the numerical value 4 is pressed alone in step Sb4, and before the pressing, the steps Sb3 to Sb4 are performed. When the invalid key 220 is pressed during the period, the numerical value string “1235” is input. In such a case, pressing a numeric key after a predetermined expiration date has passed since the pressing of the invalid key 220 may be valid.
[0066]
When the pressing of the numeric key immediately after or immediately before the pressing of the invalid key 220 is to be invalid, the display change and the generation of the electronic sound may be performed simultaneously with the single pressing of the invalid key 220, or It may be performed only for pressing.
[0067]
The automatic transaction apparatus 100 may include a setting unit that stores the form and type of the fake operation. Here, it is desirable that the setting be performed for each user. For example, the key press may be ignored for a set predetermined numerical value or numerical value sequence. In such a case, the determination process in step Sa1 of FIG. 3 performs the storage addition process of step Sa2 by comparing the form and type of the actual operation of the user with the form and type of the user stored in the setting unit. Or not.
[0068]
D. Double key:
FIG. 5 is an explanatory diagram showing a key input process using a double key.
The double key 400 has two pressing modes. The double key 400 is configured by combining a capacitance type key 401 and a mechanical key 402. The capacitance type key 401 is a key that is turned on / off in accordance with contact / non-contact of a user's finger or the like. The mechanical key 402 is a key that is turned on when a certain force is applied in addition to a simple contact of a finger or the like.
[0069]
FIG. 5 shows a state in which the double key 400 is pressed down by a deep touch and a state in which the double key 400 is pressed down by a shallow touch. When pressed down by a shallow touch, the capacitance type key 401 is turned on, but the mechanical key 402 remains off. When pressed down by a deep touch, both the capacitance type key 401 and the mechanical key 402 are turned on.
[0070]
Here, the case where the capacitance type key 401 and the mechanical key 402 are combined to form a double key has been described as an example, but the present invention is not limited to such a case. Various keys can be used as long as the key has two or more pressing modes.
[0071]
The key input process shown in FIG. 5 is a process in which a process corresponding to the processes of steps Sa0 to Sa4 in the case shown in FIG. The process in FIG. 5 differs from the key input process in FIG. 3 in that the process in step Sc1 is performed instead of step Sa1.
[0072]
If it is detected in step Sc1 that the touch mode is a shallow touch, the processing from step Sa3 is performed without performing the storage addition processing in step Sa2. This is the same as when simultaneous depression with an invalid key is detected in step Sa1 in FIG. Further, when it is detected in step Sc1 that the pressing mode is a deep touch, a storage addition process in step Sa2 is performed. This is the same as the case where the single press of the numeric key is detected in step Sa1 in FIG.
[0073]
According to the automatic transaction apparatus using the dual key 400 described above, it is difficult for a third party to distinguish between key presses in which memory addition is performed and key presses in which memory addition is not performed. Can be. Further, the user can use a general ordinary interface by using only a deep touch.
[0074]
For a user who is unfamiliar with the operation, generation of an electronic sound in step Sa4 and addition of an asterisk display in step Sa3 may not be performed when a key with a shallow touch is pressed. Conversely, a setting may be made such that storage addition is performed even when the key is pressed with a shallow touch.
[0075]
E. FIG. Circuit configuration:
FIG. 6 is an explanatory diagram illustrating a key mechanism 210a according to a modification. The key mechanism 210a has a numeric key 250a and an invalid key 220a. The numeric key 250a and the invalid key 220a send a signal related to the depression of the numeric key 250a to the control unit 300a via the electric circuit 500a. Although FIG. 6 illustrates only the numeric key 250a associated with the numerical value 1 for convenience of description, the same applies to numeric keys related to other numerical values.
[0076]
The key mechanism 210a sends, to the control unit 300a, a storage addition signal relating to addition of numerical value storage to the storage unit 314, and a display / voice signal relating to display of the display mechanism 250 and voice transmission of the voice mechanism 230.
[0077]
When the numeric key 250a is not depressed, the storage additional signal and the display / audio signal are both off. When the numeric key 250a is pressed down, the display / audio signal is turned on. The storage addition signal is also basically turned on, but in the case of simultaneous depression with the invalid key 220a, the storage addition signal remains off. Note that the same applies to a numeric key other than the numeric key 1, and the storage additional signal related to the numeric key is shut off by pressing the invalid key 220a.
[0078]
In the key input process (steps Sa0 to Sa4 in FIG. 3) when the key mechanism 210a in FIG. 6 is used, the storage addition process is performed in step Sa2 simply in response to acquiring the storage addition signal in step Sa0. I suffice. Steps Sa1, Sa3, and Sa4 are unnecessary. However, the display / audio processing corresponding to steps Sa3 and Sa4 is separately performed according to the display / audio signal.
[0079]
By using the key mechanism 210a having the electric circuit 500a described above, the secret number can be kept secret with a simple device configuration.
[0080]
Note that a circuit that is the same as or similar to the electric circuit 500a may be used in combination with the above-described double key.
[0081]
Further, in the above case, the electric signal to the control unit 300a is cut off by the electric switch. However, the electric signal may be cut off electrically by a logic circuit or the like. Further, the blocking may be performed by a mechanical mechanism. For example, there is a case where the depression of the invalid key 220a mechanically disconnects the depression of the numeric key 250a and the ON / OFF of the electric switch 501a.
[0082]
As described above, the user input recognition device according to the present invention has been described based on the embodiments. However, the embodiments of the present invention described above are for facilitating understanding of the present invention, and do not limit the present invention. Absent. The present invention can be changed and improved without departing from the spirit and scope of the claims.
