<Processing flow>
Subsequently, the processing flow of the information processing method according to the first embodiment will be described.

(Application registration process)
FIG. 8A is a sequence diagram showing an example of application registration processing according to the first embodiment. This process is an example of a process in which a developer or the like creates a custom UI application, a WF application, or the like using an information terminal 102 (or an image forming apparatus 400) or the like, and registers the created application in the service providing server 101. Shown. The web browser 701 and the custom UI creation unit 702 of FIG. 7 may be provided in the information terminal 102 or in the image forming apparatus 400.

In step S801, the developer or the like performs a template expansion operation for customizing the display screen of the application. For example, the developer or the like activates the customization tool 210 installed on the information terminal 102 or the like to execute the template expansion command.

In step S802, when the custom UI creation unit 702 receives the template expansion operation, it expands and displays the template file stored in advance. The template is a sample application or the like that serves as a template for customization, and is created in, for example, a language such as HTML, css, or Javascript.

In step S803, the developer or the like performs an operation of creating a custom UI application by using the expanded template. For example, a developer or the like creates (implements) a custom UI application 610 as shown in FIG. 6B.

The processing shown in steps S802 and S803 is an example, and the developer or the like may create (implement) a custom UI application without using the template.

After creating the custom UI application, the developer or the like performs the creation and registration process of the WF application as shown in steps S804 to S815, for example. Since the process of creating and registering the WF application is the same as the conventional technique disclosed in, for example, Patent Document 2 (Japanese Patent Laid-Open No. 2018-01479), detailed description thereof will be omitted here.

For example, in step S804, the developer or the like uses the web browser 701 to perform a display operation of the application setting screen.

In step S805, when the web browser 701 receives the display operation of the application setting screen by the developer or the like, the web browser 701 transmits the acquisition request of the application setting screen to the portal service unit 540.

In step S806, when the setting screen providing unit 541 of the portal service unit 540 receives the acquisition request of the application setting screen from the web browser 701, the setting screen providing unit 541 transmits the application setting screen to the web browser 701.

In step S807, the web browser 701 displays the application setting screen received from the setting screen providing unit 541.

In step S808, the developer or the like creates and registers the WF application by using the application setting screen displayed on the web browser 701. For example, a developer or the like creates a WF application by setting a process (for example, scanning, printing, etc.), a workflow, setting information, etc. to be executed when each operation button is selected, and performs a registration operation of the WF application. ..

In step S809, when the web browser 701 accepts the creation and registration operation of the WF application by the developer or the like, the web browser 701 transmits the registration request of the application requesting the registration of the WF application to the portal service unit 540.

In step S810, when the setting screen providing unit 541 of the portal service unit 540 receives the application registration request from the web browser 701, the received application registration request is notified to the application registration unit 542.

In step S811, the application registration unit 542 sends the notified application registration request to the application management unit 511 of the input / output service unit 510 to request the registration of the WF application.

In step S812, when the application management unit 511 receives the application registration request requesting the registration of the WF application, the application information 551 of the WF application is stored (registered) in the application information storage unit 550. Further, the application management unit 511 issues an application ID corresponding to the WF application stored in the application information storage unit 550.

In steps S813 to S815, the application management unit 511 notifies the web browser 701 via the portal service unit 540, for example, a completion notification indicating that the registration of the WF application is completed. The completion notification includes, for example, an application ID corresponding to the WF application stored in the application information storage unit 550.

In step S816, the web browser 701 displays a registration completion screen indicating that the registration of the WF application is completed. On this registration completion screen, for example, the application ID notified by the application management unit 511 is displayed. As a result, the developer or the like can confirm the application ID corresponding to the registered WF application.

(Custom UI information registration process)
FIG. 8B is a sequence diagram showing an example of the custom UI information registration process according to the first embodiment. This process may be executed, for example, following the application registration process shown in FIG. 8A, or may be executed at an arbitrary timing after the application registration process shown in FIG. 8A is executed.

In step S821, the developer or the like executes an operation of executing a deploy command that enables the customized application (custom UI application) to be used. For example, the developer or the like inputs the application ID confirmed in step S816 of FIG. 8A to execute the deploy command.

In step S822, the custom UI creation unit 702 creates a compressed file of the custom UI application when it receives the execution operation of the deploy command by the administrator or the like.

In step S823, the custom UI creation unit 702 transmits a deployment request including the created compressed file and the application ID to the portal service unit 540.

In step S824, when the application registration unit 542 of the portal service unit 540 receives the deployment request from the custom UI creation unit 702, the compressed file included in the deployment request is decompressed.

In step S825, the application registration unit 542 verifies the decompressed file. For example, the application registration unit 542 confirms the file size of the decompressed file, the number of files to be included, the presence or absence of essential files, and the like. For example, in the information processing system 100 according to the present embodiment, the file with the file name "index.html" is an essential file. For example, the screen display processing unit 521 of the web service unit 520 makes it an essential file to always read the file with the file name "index.html" when displaying the application screen in the ifram 200. Therefore, for example, if the decompressed file does not include a file with the file name "index.html", the application registration unit 542 determines that there is a problem with the decompressed file.

If there is no problem with the decompressed file, the processes after step S826 are executed. On the other hand, if there is a problem with the decompressed file, the application registration unit 542 notifies the custom UI creation unit 702 that there is a problem with the compressed file, and cancels the execution of the processes after step S826.

In step S826, the application registration unit 542 stores the custom UI information 221 including the custom UI application in the custom UI storage unit 220. The custom UI information 221 includes the application ID input in step S821.

In step S827, the application registration unit 542 notifies the application management unit 511 of the input / output service unit 510 of the storage destination information of the custom UI information 221 and information such as the application ID.

In step S828, the application management unit 511 adds and stores the storage destination of the custom UI information 221 and the application ID, etc. notified from the application registration unit 542 to, for example, the application information 551 stored in step S812.

In steps S813 to S815 of FIG. 8A, the application management unit 511 transmits the completion notification to be notified to the web browser 701 including the application ID. Further, in step S821 of FIG. 8B, the developer or the like performs an execution operation of the deploy command by using the application ID displayed on the web browser 701. As a result, the application registration unit 542 can easily specify the application information 551 to which the storage destination of the custom UI information 221 is added in step S823.

In steps S829 and S830, the application management unit 511 notifies the custom UI creation unit 702 of the completion notification indicating that the deployment process is completed via the application registration unit 542.

By the above processing of FIGS. 8A and 8B, the custom UI application created and registered by the developer or the like can be used in the information processing system 100.

(Display processing of application screen)
FIG. 9A is a sequence diagram showing an example of display processing of the application screen according to the first embodiment. This process is performed on the application screens of the custom UI application (for example, the operation screens 230a and 230b as shown in FIG. 2) created and registered by the user using the image forming apparatus 400 by the processes shown in FIGS. 8A and 8B. ) Is displayed on the image forming apparatus 400.

In step S901, it is assumed that the web browser 701 of the image forming apparatus 400 displays, for example, a list screen 920 of applications that selectively displays one or more custom UI applications as shown in FIG. 9B. ..

FIG. 9B is a diagram showing an image of a list screen of applications according to the first embodiment. On the application list screen 920, for example, as shown in FIG. 9B, a plurality of selection buttons 921a to 921f for selecting a custom UI application registered in the service providing server 101 are displayed.

The application list screen 920 is displayed on the web browser 701, for example, by a menu display application that displays the menu screen of the image forming apparatus 400, based on the application list information notified from the web service unit 520.

FIG. 9C is a diagram showing an example of list information of applications according to the first embodiment. In the example of FIG. 9C, the application list information 930 includes information 931a to 931f of a plurality of applications. In the following description, "application information 931" is used when indicating information of an arbitrary application among the information 931a to 931f of a plurality of applications.

The application information 931 includes, for example, URL information 932 of the custom UI application, name information 933, icon information 934, and the like. For example, the menu display application displays the selection button 921a for selecting "application 1" on the application list screen 920 of FIG. 9B by using the name information 933 and the icon information 934 included in the application information 931a.

Further, when the selection button 921a is selected, the menu display application transmits a display request of the application screen including the URL information 932 included in the application information 931a to the web service unit 520. In the present embodiment, the URL information 932 includes the application ID 935 as information for identifying the custom UI application. However, the information for identifying the custom UI application is not limited to the application ID 935, and for example, information other than the application ID such as the application name may be used.

The menu display application also displays the other selection buttons 921b to 921f on the application list screen 920 of FIG. 9B based on the application information 932b to 932f.

Here, returning to FIG. 9A, the description of the sequence diagram will be continued.

In step S902, the user performs a start operation of the custom UI application. For example, when the user wants to start the "application 1" on the application list screen 920 as shown in FIG. 9B, the user selects the selection button 921a of the "application 1".

In step S903, when the web browser 701 of the image forming apparatus 400 receives the start operation of the custom UI application by the user, the web browser 701 transmits an application screen display request to the screen display processing unit 521 of the web service unit 520. The display request of this application screen includes URL information 932 including the application ID 935 of the selected custom UI application.

In step S904, when the frame outer display processing unit 601 of the screen display processing unit 521 receives the display request of the application screen, the custom UI library 222 is acquired from the custom UI storage unit 220. This custom UI library 222 includes common scripts (for example, scripts for copy processing, scripts for scanning processing, etc.) that can be used from the custom UI application displayed in ifram 200.

In step S905, the frame outer display processing unit 601 of the screen display processing unit 521 notifies the frame inner display processing unit 602 of a display request requesting the display of the in-frame element (app screen of the custom UI application). The display request of the element in the frame includes, for example, the application ID acquired from the URL information 932 included in the display request of the application screen. Alternatively, the display request of the element in the frame may include the URL information 932 included in the display request of the application screen instead of the application ID.

In step S906, the frame inner display processing unit 602 acquires the custom UI information 221 corresponding to the application ID included in the display request of the in-frame element from the custom UI storage unit 220.

In step S907, the frame inner display processing unit 602 notifies the frame outer display processing unit 601 of the application information acquisition request requesting the acquisition of the application information 551 corresponding to the custom UI application. The application information acquisition request includes, for example, the application ID acquired from the display request of the in-frame element.

In step S908, the frame outer display processing unit 601 notifies the interface unit 603 of the application execution unit 522 of the application information acquisition request notified from the frame inner display processing unit 602.

In step S909, when the interface unit 603 receives the application information acquisition request from the frame outer display processing unit 601, the interface unit 603 requests the application management unit 511 of the input / output service unit 510 to acquire the application information corresponding to the application ID. To do.

In step S910, the application management unit 511 notifies the interface unit 603 of the application execution unit 522 of the application information corresponding to the requested application ID. For example, the application management unit 511 acquires the application information including the requested application ID from the application information 551 stored in the application information storage unit 550, and notifies the interface unit 603. This application information includes, for example, information such as a workflow (processing procedure) executed by the custom UI application.

In steps S911 and S912, the interface unit 603 notifies the frame inner display processing unit 602 of the acquired application information via the frame outer display processing unit 601.

In step S913, the frame inner display processing unit 602 constructs a display screen of the application to be displayed in the frame by using the acquired application information and the custom UI information. For example, the frame inner display processing unit 602 creates a customized display screen 201 (application screen of a custom UI application) as shown in FIG.

In step S914, the frame inner display processing unit 602 displays the in-frame element (application screen of the custom UI application).

In step S915, the frame outer display processing unit 601 transmits the application screen of the custom UI application to the web browser 701. For example, as shown in the operation screen 230a of FIG. 2, the frame outer display processing unit 601 transmits the operation screen 230a for displaying the application screen of the custom UI application to the web browser 701 and displays it in the ifram 200.

In step S916, the web browser 701 of the image forming apparatus 400 displays the application screen transmitted from the frame outer display processing unit 601. For example, as shown in the operation screen 230a of FIG. 2, the web browser 701 displays an application screen (operation screen 230a) for displaying the customized display screen 201 (application screen of the custom UI application) in the ifram 200.

(Processing when scanning is executed)
FIG. 10 is a sequence diagram showing an example of processing at the time of scanning execution according to the first embodiment. This process shows, for example, an example of a predetermined process executed by the information processing system 100 in response to a user's operation on the application screen displayed by the display process of the application screen shown in FIG. 9A. Here, it is assumed that the "start scanning" button for requesting the execution of the scanning process is displayed on the application screen of the custom UI application displayed in the ifram 200 of the web browser 701 of the image forming apparatus 400. I do.

In step S1001, the user presses the "scan start" button displayed on the application screen of the custom UI application displayed by the web browser 701 of the image forming apparatus 400.

In step S1002, the web browser 701 notifies the frame inner display processing unit 602 of the screen display processing unit 521 that the "scan start" button has been pressed.

In step S1003, the frame inner display processing unit 602 notifies the frame outer display processing unit 601 of a scan execution request requesting execution of the scan process by the image forming apparatus 400.

In step S1004, the frame outer display processing unit 601 notifies the interface unit 603 of the application execution unit 522 of the scan execution request received from the frame inner display processing unit 602. The frame outer display processing unit 601 performs this processing by executing the script of the custom UI library 222 described above.

In step S1005, the interface unit 603 of the application execution unit 522 executes the scan execution API included in the web API 704 of the image forming apparatus 400.

The process shown in step S1005 is an example. For example, the application execution unit 522 may execute the scan execution API of the image forming apparatus 400 via the logic processing unit 512 of the input / output service unit 510. Alternatively, the application execution unit 522 may execute the scan execution API of the image forming apparatus 400 via the SDK (Smart SDK JS) or the like for using the API of the image forming apparatus 400 provided in the service providing server 101. good.

In step S1006, the web API 704 of the image forming apparatus 400 notifies the image forming unit 705 of the scan execution command when the scan execution API is executed.

In step S1007, when the image forming unit 705 receives the scan execution command from the web API 704, the image forming unit 705 executes the scan process.

In steps S1008 and S1009, the interface unit 603 of the application execution unit 522 notifies the frame inner display processing unit 602 of the completion notification indicating that the scan process has been executed via the frame outer display processing unit 601.

In step S1010, the frame inner display processing unit 602 of the screen display processing unit 521 notifies the web browser 701 of the image forming apparatus 400 that the scanning process has been executed.

As shown in FIGS. 9A and 10, the frame inner display processing unit 602 has functions (for example, application information acquisition processing and scanning) provided in the information processing system 100 via the frame outer display processing unit 601 and the interface unit 603. Execution processing, etc.) is used.

This is because, as described above, in the "iframe" used for the frame in the present embodiment, the option "sandbox" is effectively set from the viewpoint of security. By enabling this option, it is possible to suppress the execution of unauthorized processing by the content (custom UI application) in the iframe. On the other hand, by enabling this option, the function provided in the information processing system 100 cannot be directly used from the contents in the iframe.

Therefore, in the present embodiment, the frame outer display processing unit 601 receives the request from the frame inner display processing unit 602 and executes the script of the custom UI library 222 to process information from the custom UI application in the ifram 200. The functions of the system 100 can be used.

As described above, according to the present embodiment, the developer or the like can freely customize the display screen of the application displayed by the electronic device 103 such as the image forming apparatus 400 by creating a custom UI application in which the display screen is customized. Will be able to.

[Second Embodiment]
In the second embodiment, an example will be described in which the service providing server 101 has an information management unit that manages temporary information used by the application for each application.

FIG. 11 is a diagram showing an example of the functional configuration of the web service unit according to the second embodiment. The web service unit 520 according to the second embodiment includes an information management unit 1101 in addition to the functional configuration of the web service unit 520 according to the first embodiment shown in FIG.

The information management unit 1101 is realized by, for example, an application other than the ifram 200 executed by the CPU 301 of FIG. The information management unit 1101 manages temporary information used by the application (custom UI application) in the ifram 200 for each application.

As a specific example, the first custom UI application developed by company A is loaded in the workflow200, and this first custom UI application is a process of sending scanned sentences to the input e-mail address. (Workflow) shall be executable. In addition, this first custom UI application temporarily stores the once input e-mail address (temporary information) in the information management unit 1101 outside the ifram 200. As a result, when another custom UI application (for example, a second custom UI application developed by Company B) is loaded in the ifram 200, the first custom UI application is temporarily stored in the information management unit 1101. Information can be reused.

The information management unit 1101 can use, for example, the "local storage" of the web browser 701 to manage the temporary information used by the custom UI application. local Store is a function that saves arbitrary data on the client side (web browser 701) by using Javascript. For example, in the local Storage, a storage area corresponding to each custom UI application is prepared, such as a storage area for the custom UI application of company A and a storage area for the custom UI application of company B. The information stored in the storage area for the custom UI application of company A can be reused from the custom UI application of company A, but cannot be used from the custom UI application of another company.

For example, the information management unit 1101 manages the information temporarily stored by the first custom UI application so that it cannot be accessed when the second custom UI application is loaded in the ifram 200. By managing the temporary information used by the custom UI application for each custom UI application in this way, for example, the temporary information stored by the first custom UI application can be stored by the second custom UI application. , Rewriting, etc. can be effectively suppressed.

The portal service unit 540 according to the third embodiment includes a vulnerability inspection unit 1201 in addition to the functional configuration of the portal service unit 540 according to the first embodiment shown in FIG. The vulnerability inspection unit 1201 may be included in the application registration unit 542.

The vulnerability inspection unit 1201 inspects the vulnerability of the custom UI application realized by the program executed by the CPU 301 of FIG. 3 and registered in the service providing server 101 by the developer or the like.

For example, the vulnerability inspection unit 1201 inspects the vulnerability of the decompressed custom UI application when the application registration unit 542 verifies the decompressed file in step S825 of FIG. 8B. For example, if the decompressed custom UI application has an input form, the vulnerability inspection unit 1201 verifies whether there is an injection attack (cross-site scripting, SQL injection, etc.) or other vulnerabilities.

As a specific example, the Vulnerability Inspection Unit 1201 registers in advance the knowledge necessary for solving the problem of what kind of conditions should be met and what kind of processing should be executed for vulnerability inspection as a rule. deep. In addition, the vulnerability inspection unit 1201 may detect vulnerabilities in the decompressed custom UI application based on a rule such as detecting vulnerabilities when the registered rules are met.

When the vulnerability inspection unit 1201 finds a vulnerability in the custom UI application, the application registration unit 542 cancels the registration of the custom UI application in which the vulnerability is found, for example.

The vulnerability inspection unit 1201 may be provided by the service providing server 101, and may be provided outside the portal service unit 540, for example. Further, the timing at which the vulnerability inspection unit 1201 inspects the vulnerability of the custom UI application may be a timing other than the registration of the custom UI application, such as when the custom UI application is loaded into the ifram 200.

In addition, the third embodiment can be implemented in combination with the second embodiment.

[Fourth Embodiment]
In the fourth embodiment, an example will be described in which the service providing server 101 has a public management unit that manages setting information indicating whether or not to permit the publication of the custom UI application registered by the developer. Here, the scope of disclosure indicates the scope of disclosure among developers who develop custom UI applications. With this function, developers who develop custom UI apps can choose whether to develop all custom UI apps by themselves or to develop custom UI apps using custom UI apps developed by other developers. Will be able to.

FIG. 13 is a diagram showing an example of the functional configuration of the portal service unit according to the fourth embodiment. The portal service unit 540 according to the fourth embodiment includes a public management unit 1301 in addition to the functional configuration of the portal service unit 540 according to the first embodiment shown in FIG. The public management unit 1301 may be included in the setting screen providing unit 541.

The public management unit 1301 manages setting information indicating whether or not to allow the publication of the custom UI application realized by the program executed by the CPU 301 of FIG. 3 and registered in the service providing server 101 by the developer or the like. To do.

For example, the public management unit 1301 sets a setting screen for setting whether or not to allow the publication of the custom UI application registered in the service providing server 101 by the developer or the like on the information terminal 102 (or the image forming device 400) or the like. It can be displayed on the web browser 701.
