20250131227
The present invention relates to a mobile communication terminal, a code display method, and a storage medium.
In recent years, mobile communication terminals such as smartphones display a code on their display screen, and this code is read by a code reader included in a money registry machine such as a POS (Point of Sales) register in a store or the like to make a payment (see Patent Literature 1). Also, in home delivery lockers and product receiving lockers, the code displayed on the display screen of a smartphone is read by a code reader, and after authentication of the code, the locker door is unlocked to allow users to receive products.
[PTL 1] Japanese Unexamined Patent Application Publication No. JP2018-074557
As described above, processes such as payment processing and unlocking locker doors are performed by having the code readers included in various code readers, such as POS registry machines and the like, home delivery lockers, and product receiving lockers, read the displayed codes. However, there have been problems in which the code displayed on the display screen is secretly captured and used illegally by a third party.
In this regard, a technology has been proposed in which the code is initially undisplayed and the code is made visible by touching two points on the screen with fingers. However, even with this technology, it is not possible to effectively prevent the code from being secretly captured.
The main object of the present invention is to provide a mobile communication terminal, a code display method, and a storage medium that effectively prevent a code from being secretly captured.
According to a first aspect of the present invention, there is provided a mobile communication terminal, including: a reception unit that accepts an instruction to display a code by using an input/output unit; and a display control unit that causes the code, the code being undisplayed, to be displayed when the display control unit detects a trigger indicating that the code is ready to be read.
According to a second aspect of the present invention, there is provided a code display method, including: monitoring, by using a code monitoring unit, a screen displayed on a touch panel of an input/output unit and detects whether or not a code is displayed; undisplaying, by using an undisplay unit, the code when the code is detected; and causing, by using a display control unit, the undisplayed code to be displayed when the display control unit detects a trigger indicating that the mobile communication terminal is ready for the code to be read.
According to a third aspect of the present invention, there is provided a computer-readable storage medium storing a program for a mobile communication terminal, wherein the program causes the mobile communication terminal to function as; a code monitoring unit that monitors a screen displayed on a touch panel of an input/output unit and detects whether or not a code is displayed; an undisplay unit that undisplays the code when the code is detected; and a display control unit that causes the undisplayed code to be displayed when the display control unit detects a trigger indicating that the mobile communication terminal is ready for the code to be read.
According to the individual aspects of the present invention, a mobile communication terminal, a code display method, and a storage medium that effectively prevent a code from being secretly captured are provided. The advantageous effects of the present invention are not limited to the above advantageous effect. The present invention may provide other advantageous effects, instead of or in addition to the above advantageous effect.
First, an outline of an example embodiment will be described. In the following outline, various components are denoted by reference characters for the sake of convenience. That is, the following reference characters are used as examples to facilitate the understanding of the present invention. Thus, the description of the outline is not intended to impose any limitations. In addition, unless otherwise specified, an individual block illustrated in the drawings represents a configuration of a functional unit, not a hardware unit. An individual connection line between blocks in the drawings signifies both one-way and two-way directions. An arrow schematically illustrates a principal signal (data) flow and does not exclude bidirectionality. In the present description and drawings, elements that can be described in a like way will be denoted by a like reference character, and redundant description thereof will be omitted as needed.
The mobile communication terminal 10 does not continue to display a code used for payment, or the like, but causes an undisplayed code to be displayed in response to detecting a trigger that indicates that the code is ready to be read. Therefore, there is virtually no time for a third party to secretly capture the code. Thus, according to the present application, secret capture of the code is effectively prevented.
The following is a detailed description of a mobile communication terminal, a program for a mobile communication terminal, an operation system program for a mobile communication terminal and a code display method, which effectively prevents secretly capturing a code, according to an example embodiment of the present invention. Note that the following description uses a money registry machine as an example of a code reader, but the code reader may include any device that operates by reading a code displayed on the mobile communication terminal 10, such as a delivery locker, a product receiving locker, or a washer/dryer in a laundromat, in addition to the money registry machine.
The control unit 101 includes an arithmetic apparatus such as a CPU (Central Processing Unit).
The input/output unit 102 includes a touch panel 102A that performs input by contact and display, an imaging unit 102B that includes an imaging device such as a camera and a light, a sound collection unit 102C that includes a sound collection device such as a microphone, and a vibration unit 102D that includes a vibration device such as a vibrator.
The storage unit 103 includes a storage device such as a ROM (Read Only Memory), a RAM (Random Access Memory), or a nonvolatile storage device such as a flash memory.
The storage unit 103 stores an OS (Operating System) 103A that is a so-called operation system program, an undisplay application 103B that is a program for the mobile communication terminal, and a general application 103C.
The OS 103A controls operation of each device in the mobile communication terminal 10, as well as instructs and monitors execution and suspension of each application.
The undisplay application 103B monitors contents of a screen displayed on the touch panel 102A and when a code, such as a bar code or 2D code, is displayed, the undisplay application 103B undisplays the code.
The general application 103C causes a code to be displayed on the touch panel 102A for payment or the like.
The control unit 101 reads the OS 103A from the storage unit 103 and sequentially executes the OS 103A, operates each device under the supervision of the OS 103A, and sequentially reads and executes each application.
The detection unit 104 includes an attitude detection unit 104A that includes a gyro sensor or the like to detect an attitude of the mobile communication terminal 10, and an illuminance detection unit 104B that includes a photoelectric element that detects brightness and outputs a signal.

The communication unit 105 communicates with a money registry machine such as a POS register via the short-range communication unit 105C.
The money registry machine 20 can be a so-called POS register or a money registry machine using a so-called tablet terminal. The money registry machine 20 using a tablet terminal will be described below as an example.
The money registry machine 20 includes a POS control unit 201, a POS input/output unit 202, a POS storage unit 203, a POS communication unit 204, a code reader 205, and a hand scanner 206.
The POS control unit 201 includes an arithmetic apparatus such as a CPU.
The POS input/output unit 202 includes an input/output device such as a touch panel, camera, and microphone.
The POS storage unit 203 stores an operation system program as well as a payment application that registers money and makes a payment.
The control unit 201 reads out and sequentially executes the operation system, operates each device under supervision of the operation system, and reads out and executes each application sequentially.
The POS communication unit 204 includes a short-range communication device such as a Bluetooth (registered trademark) or the like that performs short-range communication.
The code reader 205 emits a laser beam onto a code, reads the code from reflected light, converts the reflected light into an electrical signal, and outputs the electrical signal.
The hand scanner 206 is a portable device that emits a laser beam onto a code, reads out the code from reflected light, converts the reflected light into an electrical signal, and outputs the electrical signal.
In step 302, the control unit 101 monitors the screen displayed on the touch panel 102A by using the undisplay application 103B. When the control unit 101 determines that a code is displayed on the touch panel 102A, the control unit 101 undisplays the code.
The control unit 101 undisplays the code by one of the following methods using the display control unit 12.
In step 303, the control unit 101 determines whether there is a trigger to cause the code to be displayed by using the undisplay application 103B. When the control unit 101 determines that there is the trigger (Y in step 303), the flow proceeds to step 304, and when the control unit 101 does not determine that there is the trigger (N in step 303), the flow returns to step 303.
Here, the trigger will be explained. The trigger means a state of the mobile communication terminal 10 in which the mobile communication terminal 10 is in a state where a code is ready to be read.
Examples of the trigger include any of the following states.
In step 304, the control unit 101 displays the code. When the code is removed, the control unit 101 displays the removed code, and when the mask image is displayed, the control unit 101 removes the mask image from the screen.
At this time, the control unit 101 vibrates the mobile communication terminal 10 by using the vibration unit 102D or turns on the light of the imaging unit 102B. Alternatively, the control unit 101 may notify the user that the code has been displayed by generating a sound such as “beep” from a speaker included in the mobile communication terminal 10, so that the user can check that the code has been displayed without checking the screen.
In step 305, the control unit 101 determines whether the trigger has been disappeared. When the control unit 101 determines that the trigger has been disappeared (Y in step 305), the flow proceeds to step 306, and when the control unit 101 does not determine that the trigger has been disappeared (N in step 305), the flow returns to step 305.
Here, the term “the trigger has been disappeared” means a state in which the control unit 101 is no longer able to detect the above-mentioned trigger.
In step 306, the control unit 101 again undisplays the code.
In step 307, the control unit 101 determines whether a termination instruction to the general application 103C has been input. When the control unit 101 determines that the termination instruction has been input (Y in step 307), the control unit 101 terminates processing of the general application 103C, and when the control unit 101 does not determine that the termination instruction has been input (N in step 307), the flow returns to step 303.
As described above, the mobile communication terminal 10 of the first example embodiment includes the reception unit 11, which accepts an instruction to display a code by using the input/output unit 102, and the display control unit 12, which causes to be displayed an undisplayed code when the display control unit 12 detects a trigger indicating that the code is ready to be read.
Moreover, the undisplay application 103B, which is the program for the mobile communication terminal of this example embodiment, causes the mobile communication terminal 10 to function as a code monitoring unit, an undisplay unit, and a display control unit. The code monitoring unit monitors a screen displayed on the touch panel 102A of the input/output unit 102 and detects whether or not a code is displayed. The undisplay unit undisplays the code when the code is detected. When the display control unit detects a trigger indicating that the code is ready to be read, the display control unit causes the undisplayed code to be displayed.
Furthermore, in a code display method of this example embodiment, the code monitoring unit monitors a screen displayed on the touch panel 102A of the input/output unit 102 and detects whether or not a code is displayed. The undisplay unit undisplays the code when the code is detected. When the display control unit detects a trigger indicating that the mobile communication terminal 10 is ready for the code to be read, the display control unit causes the undisplayed code to be displayed.
As described above, the mobile communication terminal 10 according to the first example embodiment does not continue to display a code used for payment, or the like, but causes a code that is an undisplayed code to be displayed in response to detecting a trigger indicating that the code is ready to be read. Therefore, there is practically no time during which a third party can secretly capture the code. Therefore, according to the first example embodiment, it is effective to provide the mobile communication terminal that effectively prevents a code from being secretly captured.
The configuration of the mobile communication terminal 10 of a second example embodiment is the same as that of the mobile communication terminal 10 of the first example embodiment. Therefore, description of the configuration of the mobile communication terminal 10 of the second example embodiment is omitted.
In step 402, the control unit 101 monitors a screen displayed on the touch panel 102A by using the undisplay application 103B. When the control unit 101 determines that a code is displayed on the touch panel 102A, the control unit 101 undisplays the code.
The control unit 101 uses the display control unit 12 to undisplay the code by one of the following methods.
In step 403, the POS control unit 201 starts communication with the mobile communication terminal 10 when the POS control unit 201 determines that the mobile communication terminal 10 has entered the range where the mobile communication terminal 10 can communicate by a short-range communication device by using the POS communication unit 204.
In step 404, the control unit 101 starts communication with the money registry machine 20 in response to a request for communication from the money registry machine 20.
In step 405, the POS control unit 201 determines whether there is a trigger instruction. When the POS control unit 201 determines that there is the trigger instruction (Y in step 405), the flow proceeds to step 406, and when the POS control unit 201 does not determine that there is the trigger instruction (N in step 405), the flow returns to step 405.
Here, the trigger instruction means pressing a code display button 804A (see
An operator of the money registry machine 20 presses the code display button 804A after confirming that a user has made the mobile communication terminal 10 ready to read the code. Note that when the money registry machine 20 includes a separate user screen, the POS control unit 201 can also cause the code display button to be displayed separately on the user screen. In this case, the user presses the code display button at an arbitrary timing.
In step 406, the POS control unit 201 transmits a trigger to the mobile communication terminal 10 to cause the code to be displayed on the mobile communication terminal 10.
In step 407, the control unit 101 displays the code when the control unit 101 receives the trigger. When the code has been removed, the control unit 101 displays the removed code, and when a mask image has been displayed, the control unit 101 removes the mask image from the screen.
In step 408, the POS control unit 201 determines whether there is a deletion instruction. When the POS control unit 201 determines that there is the deletion instruction (Y in step 408), the flow proceeds to step 409, and when the POS control unit 201 does not determine that there is the deletion instruction (N in step 408), the flow returns to step 408.
Here, the deletion instruction means pressing a code undisplay button 804B (see
When an operator of the money registry machine 20 confirms that the money registry machine 20 has completed reading the code, the operator presses the code undisplay button 804B. Note that when the money registry machine 20 includes a separate user screen, the POS control unit 201 can also cause the code undisplay button to be displayed separately on the user screen. In this case, a user presses the code undisplay button at an arbitrary timing.
In step 409, the POS control unit 201 transmits to the mobile communication terminal 10 an undisplay trigger that causes the code to be undisplayed on the mobile communication terminal 10.
In step 410, the control unit 101 undisplays the code again when the control unit 101 receives the undisplay trigger.
In step 411, the control unit 101 terminates the communication with the money registry machine 20.
In step 412, the POS control unit 201 terminates communication with the mobile communication terminal 10.
As described above, the mobile communication terminal 10 in the second example embodiment causes an undisplayed code to be displayed in response to a trigger from the money registry machine 20.
Moreover, the undisplay application 103B, which is the program for the mobile communication terminal, causes the mobile communication terminal 10 to function as a code monitoring unit, an undisplay unit, and a display control unit. The code monitoring unit monitors a screen displayed on the touch panel 102A of the input/output unit 102 and detects whether or not a code is displayed. The undisplay unit undisplays a code when the code is detected. When the display control unit receives a trigger indicating that the code is ready to be read from the money registry machine 20, the display control unit causes the undisplayed code to be displayed.
Therefore, according to the second example embodiment, it is effective to provide the mobile communication terminal that enables a code to be reliably read by the money registry machine 20 and also effectively prevents the code from being secretly captured.
The configuration of the mobile communication terminal 10 of a third example embodiment is the same as that of the mobile communication terminal 10 of the first example embodiment, except that the undisplay application 103B of the mobile communication terminal 10 of the first example embodiment is embedded in the OS 103A.
The operation of the mobile communication terminal 10 in this example embodiment is the same as that of the mobile communication terminal 10 in the first example embodiment, except that the OS 103A performs the operation of the undisplay application 103B.
The OS 103A, which is the operation system program for the mobile communication terminal of this example embodiment, causes the mobile communication terminal 10 to function as a reception unit, a code monitoring unit, an undisplay unit, and a display control unit. The reception unit accepts an instruction to display a code by using the input/output unit 102. The code monitoring unit monitors the screen displayed on the touch panel 102A of the input/output unit 102 and detects whether or not a code is displayed. The undisplay unit undisplays the code when the code is detected. When the display control unit detects a trigger indicating that the code is ready to be read, the display control unit causes the undisplayed code to be displayed.
Therefore, according to the third example embodiment, it is effective to provide the mobile communication terminal that effectively prevents a code from being secretly captured without launching the undisplay application 103B.
The configuration of the mobile communication terminal 10 of a fourth example embodiment is the same as that of the mobile communication terminal 10 of the second example embodiment, except that the undisplay application 103B of the mobile communication terminal 10 of the second example embodiment is embedded in the OS 103A.
The operation of the mobile communication terminal 10 in this example embodiment is the same as that of the mobile communication terminal 10 in the second example embodiment, except that the OS 103A performs the operation of the undisplay application 103B.
The OS 103A, which is the operation system program for the mobile communication terminal of this example embodiment, causes the mobile communication terminal 10 to function as a reception unit, a code monitoring unit, an undisplay unit, and a display control unit. The reception unit accepts an instruction to display a code by using the input/output unit 102. The code monitoring unit monitors the screen displayed on the touch panel 102A of the input/output unit 102 and detects whether or not the code is displayed. The undisplay unit undisplays the code when the code is detected. When the display control unit receives a trigger from the money registry machine 20 indicating that the code is ready to be read, the display control unit causes the undisplayed code to be displayed.
Therefore, according to this example embodiment, it is effective to provide the mobile communication terminal that effectively prevents the code from being secretly captured without launching the undisplay application 103B.
The configuration of the mobile communication terminal 10 of a fifth example embodiment is the same as that of the mobile communication terminal 10 of the first example embodiment, except that the undisplay application 103B of the mobile communication terminal 10 of the first example embodiment is embedded in the general application 103C.
The operation of the mobile communication terminal 10 of this example embodiment is the same as that of the mobile communication terminal 10 of the first example embodiment, except that the general application 103C performs the operation of the undisplay application 103B.
The general application 103C, which is the program for the mobile communication terminal of this example embodiment, causes the mobile communication terminal 10 to function as a code monitoring unit, an undisplay unit, and a display control unit. The code monitoring unit detects a presence or absence of a code displayed on the touch panel 102A of the input/output unit 102. The undisplay unit undisplays the code when the code is detected. When the display control unit detects a trigger indicating that the code is ready to be read, the display control unit causes the undisplayed code to be displayed.
Therefore, according to the fifth example embodiment, it is effective to provide the mobile communication terminal that effectively prevents the code from being secretly captured without launching the undisplay application 103B.
The configuration of the mobile communication terminal 10 of a sixth example embodiment is the same as that of the mobile communication terminal 10 of the second example embodiment, except that the undisplay application 103B of the mobile communication terminal 10 of the second example embodiment is embedded in the general application 103C.
The operation of the mobile communication terminal 10 of this example embodiment is the same as that of the mobile communication terminal 10 of the second example embodiment, except that the general application 103C performs the operation of the undisplay application 103B.
The general application 103C, which is the program for the mobile communication terminal of this example embodiment, causes the mobile communication terminal 10 to function as a reception unit, a code monitoring unit, an undisplay unit, and the display control unit. The reception unit accepts an instruction to display a code by using the input/output unit 102. The code monitoring unit detects a presence or absence of the code to be displayed on the touch panel 102A of the input/output unit 102. The undisplay unit undisplays the code when the code is detected. When the display control unit receives a trigger indicating that the code is ready to be read from the money registry machine 20, the display control unit causes the undisplayed code to be displayed.
Therefore, according to the sixth example embodiment, it is effective to provide the mobile communication terminal that effectively prevents a code being secretly captured without launching the undisplayed code application 103B.
To force the code to be displayed, a user operates the mobile communication terminal 10 to set a consent button 503 to “Yes”. When the control unit 101 detects that the consent button is “Yes”, the control unit 101 displays the code regardless of a presence or absence of a trigger.
To force the code to be displayed, a user operates the mobile communication terminal 10 to set the consent button 503 to “Yes”. When the control unit 101 detects that the consent button is “Yes”, the control unit 101 displays the code regardless of a presence or absence of a trigger.
The confirmation pop-up 803 includes a code display button 804A that instructs the money registry machine 20 to transmit a trigger to the mobile communication terminal 10, and a code undisplay button 804B that instructs the money registry machine 20 to transmit an instruction to undisplay a code to the mobile communication terminal 10.
Thus, the effect is that the operator of the money registry machine 20 can safely control that the code on the mobile communication terminal 10 is displayed or undisplayed. The effect is that a user can safely control that the code on the mobile communication terminal 10 is displayed or undisplayed when a separate user screen is included on the money registry machine 20.
