Hereinafter, the program according to the present invention, the method of executing the program, and the embodiment of the terminal device will be described in detail with reference to the drawings.

(Example of execution method of the program according to the embodiment)
FIG. 1 is an explanatory diagram showing an embodiment of a method of executing a program according to an embodiment. In the example of FIG. 1, the terminal device 100 is a computer that operates a plurality of programs on its own device. The plurality of programs are, for example, a plurality of applications. Multiple applications include, for example, mobile applications and external applications.

In the following description, a mobile application may be referred to as a "mobile application". In the following description, an external application may be referred to as an "external application". The terminal device 100 is, for example, a smartphone or a tablet terminal.

Here, it may be desired to expand the functions of a mobile application that has been introduced or distributed in advance on a smartphone or the like and operates on the smartphone or the like. For example, it is conceivable to add a plug-in to a mobile application to expand the function of the mobile application and then distribute the mobile application to a smartphone or the like.

However, in this case, adding a plug-in to the mobile application causes an increase in the data size of the mobile application. Also, changing the plugin may lead to an increase in the data size of the mobile app. For this reason, when the mobile application is distributed, the communication load on the smartphone or the like is increased.

Further, in this case, the plug-in added to the mobile application uses the memory capacity allocated to the mobile application from the OS (Operating System) in common with the main routine of the mobile application. Therefore, the memory capacity used by the mobile application may be larger than the memory capacity allocated to the mobile application from the OS, and the memory capacity may be insufficient.

On the other hand, it is conceivable that the functions of the mobile application may be expanded by linking the mobile application with the external application. For example, a mobile application may activate an external application such as a barcode reader via a URL scheme (Uniform Resource Locator Scene). It is conceivable that the external application sends the data to the mobile application via the URL scheme.

However, in this case, since the external application uses the URL scheme, the mobile application is moved to the foreground each time the data is transmitted to the mobile application. Therefore, when the external application transmits a plurality of data to the mobile application, the convenience of the smartphone or the like may be reduced.

For example, it is conceivable that the user causes the external application to read multiple data one by one, but each time the external application reads the data, the external application sends the data to the mobile application and moves it to the background. Become. For this reason, the user has to move the external application back to the foreground each time the external application reads the data, which reduces the convenience of the smartphone or the like.

On the other hand, it is conceivable that the external application sends multiple data to the mobile application at once after the user has the external application read multiple data, but the external application reads some data. It may be forcibly terminated with and the read data may be lost. For this reason, the user will have the external application read some of the multiple data, and then if the external application is forcibly terminated, the user will be forced to read the multiple data again, reducing the convenience of smartphones and the like. Resulting in.

Further, in this case, the mobile application may receive data via the URL scheme even from a malicious application different from the launched external application. For this reason, mobile apps may reduce the security of smartphones and the like.

In addition, when the mobile app launches the external app, it passes the identification information that identifies the mobile app to the external app, and if the received data does not have that identification information, the data is discarded. It is possible that you will. However, even in this case, the mobile application cannot discard the data from the malicious application when the identification information passed to the external application in the past is diverted to the unauthorized application.

Therefore, in the present embodiment, the mobile application is included in the instruction issued to the external application via the URL scheme, and the cooperation between the applications is realized by using the instruction identification information that identifies the instruction itself. Explain how to execute an external application.

In the example of FIG. 1, the terminal device 100 can operate the first application 101 and the second application 102 on its own device. The first application 101 is an external application launched by the mobile application. The external application is, for example, a barcode reader. The second application 102 is a mobile application.

(1-1) The first application 101 is activated in response to an operation instruction including instruction identification information from the second application 102. For example, the mobile application launches an external application through the OS by executing a URL scheme that includes instruction identification information. As a result, the external application can acquire the instruction identification information.

(1-2) The first application 101 executes an operation corresponding to an operation instruction. The external application reads data from the barcode, for example, based on the user's operation input. As a result, the external application is the output target and can read the data to be acquired by the mobile application.

(1-3) When the operation includes the output of data, the first application 101 associates the data with the instruction identification information and stores the data in a storage area that can be referred to by the second application 102. The external application, for example, stores the read data in a storage area that can be referred to by the mobile application in association with the instruction identification information included in the operation instruction.

On the other hand, the second application 102 can read the data stored by the first application 101 from the storage area and acquire the data, and can use the data. As a result, the external application can realize the cooperation with the mobile application and can increase the functions of the terminal device 100 without adding a plug-in to the mobile application.

Further, the terminal device 100 can suppress an increase in the data size of the mobile application by linking the mobile application and the external application. Then, the creator of the mobile application does not have to change the mobile application and does not have to increase the data size of the mobile application even if the external application is changed to increase the data size of the external application. Therefore, if the creator re-distributes the external application, the mobile application does not have to be re-distributed, and the communication load on the terminal device 100 can be reduced. Similarly, the creator does not have to redistribute the external app even if the mobile app is changed.

Further, the terminal device 100 can allocate memory capacity to the mobile application and the external application, respectively, depending on the OS. Therefore, the terminal device 100 can reduce the possibility that the memory capacity used by the mobile application becomes larger than the memory capacity allocated to the mobile application from the OS and the memory capacity becomes insufficient. Similarly, in the terminal device 100, the memory capacity used by the external application becomes larger than the memory capacity allocated to the external application from the OS, and the possibility that the memory capacity becomes insufficient can be reduced.

In addition, the external application can save the data each time it acquires the data. Therefore, the external application can reduce the possibility of losing data even if it is forcibly terminated. In addition, the external application can reduce the possibility of losing the data without transmitting the data to the mobile application each time the data is acquired.

In addition, the external application does not have to send the data to the mobile application each time the data is acquired to move the mobile application to the foreground. For this reason, when the user tries to input the operation to acquire multiple data in succession, the external application moves the mobile application to the foreground each time the data is acquired, which makes it difficult for the user to input the operation. It is possible to reduce the possibility of doing so.

The recording medium I / F 204 is, for example, a disk drive, an SSD (Solid State Drive), a USB (Universal Serial Bus) port, or the like. The recording medium 205 is a non-volatile memory that stores data written under the control of the recording medium I / F 204. The recording medium 205 is, for example, a disk, a semiconductor memory, a USB memory, or the like. The recording medium 205 may be detachable from the terminal device 100. The recording medium 205 may store the application according to the embodiment.

The touch panel 206 has a display for displaying data such as documents, images, and functional information, as well as a cursor, an icon, or a toolbox. The touch panel 206 is provided on the display or on the outer peripheral portion of the display, and has a detection device for detecting the contact position of the user on the touch panel 206. The detection device detects the contact position by using, for example, a resistance film method, a capacitance method, an ultrasonic method, an optical method, an electromagnetic induction method, or the like.

(Example of functional configuration of terminal device 100)
Next, a functional configuration example of the terminal device 100 will be described with reference to FIG.

FIG. 6 is a block diagram showing a functional configuration example of the terminal device 100. The terminal device 100 includes an activation unit 601, an execution unit 602, and an output unit 603.

The activation unit 601 to the output unit 603 are functions that serve as control units. Specifically, the activation unit 601 to the output unit 603 may cause the CPU 201 to execute a program stored in a storage area such as the memory 202 or the recording medium 205 shown in FIG. 2, or the network I / F 203. To realize the function. The processing result of each functional unit is stored in a storage area such as the memory 202 or the recording medium 205 shown in FIG. 2, for example.

The activation unit 601 activates the first application 101. The first application 101 is an application that operates on the terminal device 100. The first application 101 is, for example, an external application. The activation unit 601 activates the first application 101, for example, based on an operation instruction including instruction identification information from the second application 102. The second application 102 is an application that operates on the terminal device 100. The second application 102 is, for example, a mobile application. The instruction identification information is, for example, an identification ID. The operation instruction includes, for example, an identification ID that identifies the operation instruction. The operation instruction may further include the path of the target file as a storage destination for storing the data obtained by the operation corresponding to the operation instruction. The operation instruction is, for example, a URL scheme.

Specifically, the activation unit 601 activates the external application by executing the URL scheme including the identification ID created by the mobile application. As a result, the external application can acquire the identification ID that identifies the URL scheme based on the URL scheme, and the target file that is the save destination for saving the data obtained by performing the operation corresponding to the URL scheme. You can get the path of.

The execution unit 602 executes the first application 101. The execution unit 602 executes the operation corresponding to the operation instruction by executing the first application 101. The operation is, for example, reading data from a barcode and outputting read data. For example, when the operation includes the output of data, the execution unit 602 associates the data with the instruction identification information and stores the data in a storage area that can be referred to by the second application 102.

The execution unit 602 reads data from the barcode based on the URL scheme from the mobile application, for example, by executing the external application, and saves the data in the target file in association with the identification ID. As a result, the execution unit 602 can make the mobile application specify and acquire the data created by the external application corresponding to the URL scheme created by the mobile application.

Further, the operation may include an operation of interrupting the process performed at the start of the first application 101 or terminating the first application 101 when the instruction identification information does not satisfy a predetermined condition. For example, if the identification ID does not match the preset format, the execution unit 602 may interrupt the process performed when the external application is started and terminate the external application. The format is, for example, the format of the first character of the identification ID. The format may be, for example, a format in which the identification ID includes parity. As a result, the execution unit 602 can prevent the external application from being used by the malicious application.

For example, when the instruction identification information has been acquired in the past and the predetermined time has elapsed from the time when the instruction identification information was acquired, the execution unit 602 interrupts the process performed when the external application is started. , You may quit the external application. As a result, the execution unit 602 can prevent the external application from being used by the unauthorized application even when the unauthorized application diverts the identification ID created in the past by the mobile application.

Further, the operation instruction may further include information indicating a storage area designated for the second application 102 and in which the instruction identification information is stored. The storage area in which the instruction identification information is stored is, for example, a target file. The execution unit 602 saves the identification ID in the target file by the external application, for example, in response to the activation of the external application. As a result, the execution unit 602 can store the identification ID in the target file as information indicating that the external application has been started.

For example, when the execution unit 602 saves the data in the target file, the execution unit 602 may save the point-of-sale information about the data in association with the data. Specifically, the execution unit 602 stores point-of-sale information indicating a time point when data is acquired, a time point when data is created, a time point when data is saved, and the like. As a result, the execution unit 602 can store information for the mobile application to determine the operating state of the external application.

The execution unit 602 executes the second application 102. By executing the second application 102, the execution unit 602 identifies information indicating a storage area that can be referred to by the first application 101 and the operation instruction in the operation instruction to the first application 101. It can include instructional identification information. Then, the execution unit 602 can issue an operation instruction to the first application 101.

The execution unit 602, for example, includes a URL scheme that is an operation instruction to an external application, an identification ID that identifies the URL scheme, and a path of a target file that is a storage destination of data acquired by the external application. Can be issued. As a result, the execution unit 602 can have the external application save the data in the target file in association with the identification ID. Therefore, the execution unit 602 can enable the mobile application to identify and acquire the data corresponding to the issued URL scheme.

The execution unit 602 monitors the storage area by executing the second application 102, and is stored in the storage area in association with the instruction identification information by the first application 101 activated in response to the operation instruction. Get the data. The execution unit 602 can, for example, monitor the target file and acquire the data written in the target file in association with the identification ID by the external application.

Further, the execution unit 602 may delete the data from the storage area when the difference between the time when the operation instruction is issued and the time when the data is written to the storage area is equal to or more than the threshold value. For example, when the difference between the issue date and time of the instruction management DB 300 and the input date and time of the file DB 500 is equal to or greater than the threshold value, the execution unit 602 deletes the data without acquiring data from the target file. As a result, the execution unit 602 can suppress the deterioration of security.

Further, when the execution unit 602 acquires the data, the execution unit 602 may delete the data from the storage area. For example, when the execution unit 602 acquires data from the target file, the execution unit 602 duplicates the data in the content DB 400 and deletes the data from the target file. As a result, the execution unit 602 can prevent the data written by the external application from being illegally used later and suppress the deterioration of security.

The output unit 603 has a function of outputting the data acquired by the first application 101 and the second application 102. Further, the output unit 603 may further have a function of outputting information indicating the activation state and the cooperation state of the first application 101 and the second application 102. The output format is, for example, display on a display, display on a touch panel 206, print output to a printer, transmission to an external device by network I / F 203, or storage in a storage area such as a memory 202 or a recording medium 205. Is.

(Example 1)
Next, Example 1 will be described with reference to FIGS. 7 and 8.

7 and 8 are explanatory views showing the first embodiment. In the example of FIGS. 7 and 8, the terminal device 100 can operate the mobile application 710 and the external application 720 on the own device. The mobile application 710 has a UI processing unit 711 and an application management unit 713.

The UI processing unit 711 provides one or more contents via the browser 712. The UI processing unit 711 receives an operation input from the user 701 via the browser 712. The application management unit 713 activates the external application 720. The application management unit 713 has a monitoring unit 714. The monitoring unit 714 monitors the data stored in the external application 720.

In the example of FIG. 7, (7-1) the mobile application 710 requests the UI processing unit 711 to start the external application 720 from the user 701 using the touch panel 206 or the like in any of the contents provided by the browser 712. Accepts the operation input to be performed. The mobile application 710 notifies the application management unit 713 from the UI processing unit 711 of the operation input requesting the activation of the external application 720.

Further, the mobile application 710 notifies the application management unit 713 from the UI processing unit 711 of the content ID of the content for which the operation input has been accepted. As a result, the mobile application 710 can notify the application management unit 713 which external application 720 is to be activated and which content uses the data stored in the external application 720.

(7-2) The mobile application 710 generates an identification ID for identifying an operation instruction to be issued next by the application management unit 713. Further, the mobile application 710 generates a target file in the file DB 500 in which data is saved by the external application 720 activated by the operation instruction to be issued next by the application management unit 713, and generates a path of the target file. Further, the mobile application 710 generates a content ID of the content for which the operation input is accepted by the application management unit 713.

The mobile application 710 is stored in the instruction management DB 300 in association with the generated identification ID, the path, and the content ID by the application management unit 713. The mobile application 710 creates a URL scheme that serves as an operation instruction including the generated identification ID and the path by the application management unit 713. The mobile application 710 starts monitoring the writing status of the data to the generated target file by the monitoring unit 714. As a result, the mobile application 710 can reduce the time required from the external application 720 writing the data to the target file until the data is acquired. Further, since the mobile application 710 does not include the content ID in the URL scheme, the possibility that the content ID is diverted to the unauthorized application can be reduced.

(7-3) The mobile application 710 executes the URL scheme created by the application management unit 713. As a result, the mobile application 710 can start the external application 720 through the OS. Further, the mobile application 710 can cause the external application 720 to perform a predetermined operation corresponding to the operation instruction and save the data in the target file. Further, since the mobile application 710 does not pass the content ID to the external application 720, the possibility that the content ID is diverted to the unauthorized application can be reduced.

(7-4) The external application 720 is started through the OS. When the external application 720 is started, the identification ID included in the URL scheme and the path of the target file are acquired. The external application 720 associates the acquired identification ID with the input date and time based on the acquired path, and saves the acquired identification ID in the target file of the file DB 500. The mobile application 710 acquires data such as an identification ID and an input date and time written in the target file by the monitoring unit 714 and stores the data in the content DB 400.

As a result, the mobile application 710 can detect that the external application 720 is activated by the monitoring unit 714 even if the external application 720 does not respond to the URL scheme. Further, the mobile application 710 can acquire the date and time when the external application 720 is activated by the monitoring unit 714. The mobile application 710 can grasp whether or not the external application 720 has been successfully started by the monitoring unit 714. Next, the description shifts to FIG.

In the example of FIG. 8, (8-1) the external application 720 acquires data in response to an operation input from the user 701 using a touch panel 206 or the like. The external application 720 realizes the function of a barcode reader, for example, and reads data from the barcode.

(8-2) The external application 720 encrypts the read data by using the identification ID. The external application 720 stores the acquired identification ID, the encrypted data obtained by encryption, and the input date and time in association with each other in the target file of the file DB 500 based on the acquired path. Here, the external application 720 may also encrypt the identification ID and the input date and time stored in the target file. As a result, the external application 720 can improve the security.

(8-3) The mobile application 710 acquires the identification ID written in the target file, the encrypted data, and the input date and time by the monitoring unit 714, and decrypts the encrypted data. The mobile application 710 may delete the encrypted data without decrypting it if the acquired identification ID is an identification ID for which a predetermined time has elapsed since it was generated, based on the issue date and time of the instruction management DB 300. Further, when the mobile application 710 acquires the encrypted data, the mobile application 710 deletes the encrypted data from the target file. As a result, the mobile application 710 can prevent the acquired encrypted data from being used by an unauthorized application and can improve security.

(8-4) If the identification ID acquired by the monitoring unit 714 is an identification ID for which a predetermined time has not elapsed since it was generated, the mobile application 710 can be used as the identification ID acquired based on the instruction management DB 300. Identify the corresponding content ID. The mobile application 710 stores the identification ID acquired by the monitoring unit 714, the data obtained by decoding, and the specified content ID in association with each other in the content DB 400. Thereby, the mobile application 710 can specify which content is to be used for the acquired data.

(8-5) The mobile application 710 is moved to the foreground by the UI processing unit 711 in response to an operation input from the user 701 using the touch panel 206 or the like. As a result, the mobile application 710 does not move to the foreground when the external application 720 continuously acquires a plurality of data, and it is easy to input the operation of the user 701 via the external application 720. can do.
