The acquisition unit 53 also executes acquisition of backup information from the information processing device 7. Before information deletion is executed, a setting as to whether or not to back up information is acquired from a data table that manages settings related to the necessity of backup, and if the setting is to back up information, the acquisition unit 53 acquires backup information from the information processing device 7 to be deleted. In this embodiment, the acquisition unit 53 functions as an example of an acquisition means.

[0054] The display control unit 54 is mainly realized by the processing of the CPU 501 on the display 507 or the display 307 of the communication terminal 3, and performs display control of various screens and information (data) on the server device 5 or the communication terminal 3. The display control unit 54 also causes the communication terminal 3 to display the display screen generated by the server device 5 on the display 307 of the communication terminal 3 using a browser in HTML or the like. The display control unit 54 also causes the display 307 to display a screen for accepting an instruction to delete information stored in the information processing device. The display control unit 54 also causes the display 307 to display a screen for setting a period for storing the received information in the storage unit 5000 (an example of a storage means). The display control unit 54 also causes the display 307 to display a screen for accepting selection of the target information. The display control unit 54 also causes the display 307 to display a screen for accepting a deletion instruction for each information processing device 7. The display control unit 54 also causes the display 307 to display a screen for accepting selection of the information processing device 7. The display control unit 54 also causes the display 307 to display a screen for accepting instructions related to restoration. The display control unit 54 also causes the display 307 to display a screen on which information to be restored can be selected. The display control unit 54 further causes the display 307 to display a screen on which an information processing device 7 to be restored can be selected.

[0055] The display control unit 54 also has a function as a device management UI that displays various operation screens and notification screens on the communication terminal 3. When the deletion setting of the information stored in the information processing device 7 is saved, the display control unit 54 performs display control to notify the user that the deletion setting has been saved. The display control unit 54 further has a function of prompting the user to check whether or not there is a problem with the information deletion setting by displaying a warning message related to the deletion of information on the communication terminal 3. In this embodiment, the display control unit 54 functions as an example of a display control means.

[0056] The determination unit 55 is mainly realized by the processing of the CPU 501, and performs determination processing for the entire server device 5. The determination unit 55 also determines whether the information processing device 7 can be designated as a target for deleting information. In this case, the determination unit 55 checks the contents of a data table, which will be described later, and determines whether the information processing device 7 to be deleted is appropriate as a target for deleting information. In this embodiment, the determination unit 55 functions as an example of a determination means.

[0057] The execution control unit 56 is mainly realized by the processing of the CPU 501. The execution control unit 56 controls the execution when the information processing device 7 deletes information of its own device. When the setting for receiving information is not set, the execution control unit 56 deletes information based on a deletion request in a state in which the transmitting / receiving unit 51 does not receive information. The execution control unit 56 restores information deleted by the information processing device 7 to the information processing device 7 based on the information (device backup information) stored in the storage unit 5000. The execution control unit 56 has a function of operating the functions of the information processing device 7 from the device management UI. The execution control unit 56 is a functional unit that cooperates with the display control unit 54 when the communication terminal 3 displays a warning message related to the deletion of information. The execution control unit 56 deletes information from the information processing device 7. The execution control unit 56 acquires execution settings such as the information processing device 7 to be deleted and a schedule from a data table described later, and deletes information according to the settings. When the information is stored by the storage readout unit 59, the execution control unit 56 further controls the deletion of the information stored in the storage unit 5000 after the period accepted on the screen for setting the period for storing the information has elapsed. Specifically, when the information is stored in the storage unit 5000 of the server device 5 by the storage readout unit 59 in step S47, the execution control unit 56 executes the deletion of the information stored in the storage unit 5000. When the information is stored in a storage unit of a device other than the server device 5 by the storage readout unit 59 in step S47, the execution control unit 56 transmits an instruction to delete the information to the device other than the server device 5 that has the storage unit. In this embodiment, the execution control unit 56 functions as an example of a deletion control means and an example of a restoration control means.

[0058] The generation unit 57 is mainly realized by the processing of the CPU 501, and generates various data including various screen data to be displayed on the communication terminal 3. In this embodiment, the generation unit 57 functions as an example of a generation means.

[0059] The setting registration unit 58 is mainly realized by the processing of the CPU 501, and sets and registers information in various data tables managed by the server device 5. In this embodiment, the setting registration unit 58 functions as an example of a registration means.

[0060] The storage / reading unit 59 is mainly realized by the processing of the CPU 501 on at least one of the ROM 502, the EEPROM 504, the HD 505, and the recording medium 514, and stores various data (or information) in the storage unit 5000 and reads various data (or information) from the storage unit 5000. The storage / reading unit 59 stores the information received by the transmission / reception unit 51 in a storage means of a device other than the information processing device 7 to be deleted, or in a storage means of the server device. Specifically, the storage / reading unit 59 stores the information received by the transmission / reception unit 51 in the storage unit 5000 of the server device 5. In this embodiment, the storage / reading unit 59 functions as an example of a storage control means. The storage means may be, for example, a storage means of the other information processing device 7, an online storage connectable to the server device, or an external storage medium, as long as it is provided in a device other than the information processing device 7 to be deleted.

[0061] ●Target device information management table● Fig. 6 is a conceptual diagram showing an example of a target device information management table according to an embodiment. Note that the structure of the data table described below is an example, and is not limited to this. A target device information management DB 5001 configured by a target device information management table as shown in Fig. 6 is constructed in the storage unit 5000. In the target device information management table, items including a device display name, an IP address, a serial number, and a model name are associated with each target device ID, stored, and managed.

[0062] Of these, the target device ID is identification information that identifies the information processing device 7 that is to be the target for information deletion. The device display name is the name of the information processing device 7 that corresponds to the target device ID. The IP address is the IP address assigned to the target device. The serial number is the serial number of the target device. The model name is the model name of the target device. In this manner, the target device information management table stores and manages information on the information processing device 7 managed by the server device 5. The target device information management table makes it possible to specify the information processing device 7 from which information deletion or restoration is to be performed, from the device management UI via the display 307 of the communication terminal 3.

[0063] In this embodiment, the target device information management table (target device information management DB 5001) functions as an example of a target device information management means.

[0064] ●Device Information Deletion Target Management Table● Fig. 7 is a conceptual diagram showing an example of a device information deletion target management table according to an embodiment. Note that the data table structure described below is an example, and is not limited to this. A device information deletion target management DB 5002 configured by the device information deletion target management table as shown in Fig. 7 is constructed in the storage unit 5000. In the device information deletion target management table, the items of the deletion target device name, IP address, and device / group are associated with each target device ID, stored, and managed.

[0065] Of these, the deletion target device name is managed with the same contents as the device display name managed in the target device information management table. The device / group distinguishes whether the deletion target device is a device or belongs to a specific group. In this way, the device information deletion target management table holds information related to the device information deletion target of the information processing device 7. The device information deletion target management table allows the information processing device 7, from which information is to be deleted or restored, to be specified from the device management UI via the display 307 of the communication terminal 3.

[0066] In this embodiment, the device information deletion target management table (device information deletion target management DB 5002) functions as an example of a service management means. The target device information management table and the device information deletion target management table may be an integrated table. In this case, the integrated table can be used to specify the information processing device 7 from which information is to be deleted or restored, from a device management UI via a display of a communication terminal.

[0067] ●Device Information Deletion Settings Management Table● Fig. 8 is a conceptual diagram showing an example of a device information deletion setting management table according to an embodiment. Note that the data table described below is an example and is not limited to this. A device information deletion setting management DB 5003 configured by a device information deletion setting management table as shown in Fig. 8 is constructed in the storage unit 5000. In the device information deletion setting management table, the items of the device name to be deleted and the deletion schedule are associated with each target device ID, stored, and managed.

[0068] Among these, the deletion schedule includes the deletion start date and time and the deletion start time. These indicate the date and time information and the time information when the deletion target device is deleted. In this way, the device information deletion setting management table holds the execution settings (execution settings of the target information processing device 7, deletion schedule, etc.) when executing the deletion of information related to the information processing device 7.

[0069] In this embodiment, the device information deletion setting management table (device information deletion setting management DB 5003) functions as an example of a device information deletion setting management means.

[0070] ●Device Information Deletion Result Management Table● Fig. 9 is a conceptual diagram showing an example of a device information deletion result management table according to an embodiment. Note that the data table described below is an example and is not limited to this. A device information deletion result management DB 5004 configured by a device information deletion result management table as shown in Fig. 9 is constructed in the storage unit 5000. In the device information deletion result management table, the items of the device name to be deleted and the deletion result storage location are associated with each target device ID, stored, and managed.

[0071] Among these, the deletion result storage location indicates a location for storing the deletion result of the information related to the information processing device 7 to be deleted, and for example, a predetermined URL is specified. In this manner, in the device information deletion result management table, the location for storing the deletion result is associated with each information processing device 7 to be deleted, and is stored and managed.

[0072] In this embodiment, the device information deletion result management table (device information deletion result management DB 5004) functions as an example of a device information deletion result management means.

[0073] ●Backup necessity setting management table● Fig. 10 is a conceptual diagram showing an example of a backup necessity setting management table according to an embodiment. Note that the data table described below is an example and is not limited to this. A backup necessity setting management DB 5005 configured by a backup necessity setting management table as shown in Fig. 10 is constructed in the storage unit 5000. In the backup necessity setting management table, items such as backup necessity and device backup information retention period are associated with each other and stored and managed for each task ID.

[0074] Among these, the task ID is identification information for identifying the deletion task. The backup necessity is a flag for managing the necessity of backing up the information to be deleted from the information processing device 7 to be deleted before executing the deletion. The backup necessity is managed, for example, as "necessary (valid)" or "not necessary (invalid)". The device backup information storage period indicates the storage period of the backed up information, and is managed by a predetermined time or number of days. The storage period may be unlimited (unlimited). When the backup information is registered in step S47 of the deletion task described later, the device information deletion setting management table is referred to to identify the deletion start date and time, and when the storage period associated with the task has elapsed from the deletion start date and time, the server device may further have a storage deletion instruction unit that instructs the storage unit registered in the task to delete the information. In this way, in the backup necessity setting management table, the backup necessity and the storage period of the backup information are associated with each task to be deleted, and are stored and managed. It is also possible to consider a method in which the backup necessity setting management table does not associate with each task ID as described above, but unifies the backup necessity for each tenant using the management system. That is, when a backup necessity setting is accepted in steps S16 to S19 described later, the backup necessity setting management table for that tenant is updated. In this case, in step S42 described later, the backup necessity setting management DB 5005 is referenced to determine whether the tenant needs a backup.

[0075] In this embodiment, the backup necessity setting management table (backup necessity setting management DB 5005) functions as an example of a backup necessity setting management means.

[0076] ●Backup information management table● Fig. 11 is a conceptual diagram showing an example of a backup information management table according to an embodiment. Note that the data table described below is an example, and is not limited to this. A backup information management DB 5006 configured by a backup information management table as shown in Fig. 11 is constructed in the storage unit 5000. In the backup information management table, device backup information is associated with each target device ID, stored, and managed.

[0077] Among these, the device backup information includes the serial number of the information processing device 7. In this manner, in the backup information management table, various information of the information processing device 7 to be deleted is associated with each information processing device 7 from which information is deleted, and is stored and managed.

[0078] When restoring after storing device backup information in the backup information management table, the settings of the information processing device 7 to be deleted when setting a restoration task are selected from the information processing device 7 for which device backup information exists. Therefore, the server device 5 newly generates device information of the information processing device 7 for which backup is taken in the backup information management table and a task for setting the backup information of the information processing device 7. This eliminates the need for association between the setting (task ID) of the task for setting whether or not backup is required and the task information managed in the backup information management table.

[0079] In this embodiment, the backup information management table (backup information management DB 5006) functions as an example of a backup information management means.

[0095] [Processing or Operation of the Embodiment] Next, each process or operation in the information processing system according to the embodiment will be described with reference to FIGS.

[0096] <Processing including backup necessity setting processing> First, a process including a backup necessity setting process will be described. FIG. 14 is a sequence diagram showing an example of a process including a backup necessity setting process according to the embodiment. As shown in FIG. 14, the operation acceptance unit 32 of the communication terminal 3 accepts the start of a web browser (step S11). Specifically, a user who uses the management system 1 starts a web browser by accessing a device information management app or a predetermined URL using the communication terminal 3. As a result, the operation acceptance unit 32 of the communication terminal 3 accepts the start of the device information management app or the web browser. Note that after accepting the start of the device information management app or the web browser, a login process performed as necessary, establishment of a session between the communication terminal 3 and the server device 5, and the like are performed using, for example, a conventional method, and detailed explanations thereof will be omitted.

[0097] Next, the transmitting / receiving unit 31 transmits a screen data acquisition request to the server device 5 (step S12). As a result, the transmitting / receiving unit 51 of the server device 5 receives the screen data acquisition request transmitted by the communication terminal 3.

[0098] Next, the generating unit 57 of the server device 5 generates screen data (step S13). Specifically, the generating unit 57 generates backup necessity setting screen data at the time of deleting device information, which represents a backup necessity setting screen at the time of deleting device information, to be described later, based on the information included in the screen data acquisition request received at step S12.

[0099] Next, the transmitting / receiving unit 51 transmits a screen data acquisition response to the communication terminal 3 as a response to the screen data acquisition request (step S14). As a result, the transmitting / receiving unit 31 of the communication terminal 3 receives the screen data acquisition response transmitted by the server device 5. At this time, the screen data acquisition response includes device information deletion backup necessity setting screen data representing a device information deletion backup necessity setting screen.

[0100] Next, the display control unit 34 of the communication terminal 3 causes a backup necessity setting screen for device information deletion to be displayed on the display 307 of the communication terminal 3 (step S15).

[0101] ●Screen display example● Here, an example of a display screen in the communication terminal 3 will be described. FIG. 15 is a diagram showing an example of a backup necessity setting screen when deleting device information according to the embodiment. As shown in FIG. 15, a backup necessity setting screen 3111 when deleting device information is displayed by the display control unit 34 on the display 307 of the communication terminal 3. The backup necessity setting screen 3111 when deleting device information is one of the screens in the items of "Server setting" and "Device information deletion setting" in the "System" menu, and displays a radio button for selecting whether or not to back up device information before deletion (enabled or disabled), an input area for inputting the device backup information storage period, and a save button 3151 as a backup necessity setting when deleting device information. This allows the user to input and set whether or not to back up specific information of the information processing device 7 to be deleted, and the backup information storage period when performing backup.

[0102] 14, the judgment unit 35 of the communication terminal 3 judges whether a backup is necessary (step S16). Specifically, the judgment unit 35 checks whether a radio button for selecting whether a pre-deletion device information backup is necessary (enabled or disabled) displayed in step S15 is necessary (enabled or disabled).

[0103] When the radio button for "No (Disabled)" backup is selected, the operation accepting unit 32 accepts an operation of the disable button and an operation of the save button, and executes the processes of steps S19 to S22 described later (step S17).

[0104] On the other hand, when the radio button for backup "Necessary (enabled)" is selected, the operation accepting unit 32 accepts an operation of the disable button, an input of the device backup information storage period, and an operation of the save button (step S18). Specifically, the operation accepting unit 32 accepts the setting of the storage period based on an input to an input area for inputting the device backup information storage period displayed on the backup necessity setting screen 3111 at the time of deleting device information shown in FIG. 15.

[0105] Next, the transmitting / receiving unit 31 transmits a backup necessity setting request to the server device 5 (step S19). As a result, the transmitting / receiving unit 51 of the server device 5 receives the backup necessity setting request transmitted by the communication terminal 3. At this time, the backup necessity setting request includes backup necessity information (information selected by the radio button) and device backup information storage period information.

[0106] Next, the storage / reading unit 59 of the server device 5 saves the backup necessity setting at the time of deleting the device information (step S20). Specifically, the storage / reading unit 59 stores the backup necessity information (information selected by the radio button) and the device backup information storage period information included in the backup necessity setting request received in step S19 in the items corresponding to the task IDs in the backup necessity setting management DB 5005 (see FIG. 10). Note that, when the process of step S20 is executed, for example, the setting registration unit 58 issues a task ID, and the backup necessity information, the device backup information storage period, etc. are stored in the items corresponding to the issued task ID.

[0107] Next, the transmitting / receiving unit 51 transmits a backup necessity setting response as a response to the backup necessity setting request to the communications terminal 3 (step S21). As a result, the transmitting / receiving unit 31 of the communications terminal 3 receives the backup necessity setting response transmitted by the server device 5. At this time, the backup necessity setting response includes data storage result screen data representing a data storage result screen including the contents of the backup necessity setting at the time of deleting device information performed in step S20.

[0108] Next, the display control unit 34 of the communication terminal 3 causes the display 307 to display a data storage result screen (step S22). Specifically, the display control unit 34 causes the display 307 of the communication terminal 3 to display a data storage result screen as shown below.

[0109] The above is an explanation of each process according to the result of the backup necessity determination.

[0110] ●Screen display example● Here, an example of a display screen in the communication terminal 3 will be described. FIG. 16 is a diagram showing an example of a data storage result screen according to the embodiment. As shown in FIG. 16, a data storage result screen 3112 is displayed on the display 307 of the communication terminal 3 by the display control unit 34. The data storage result screen 3112 is one of the screens in the items of "Server setting" and "Device information deletion setting" in the "System" menu, and is a screen displayed in response to a user's input for the setting of whether or not to back up when deleting device information. In the data storage result screen 3112, a dialogue 3113 including a message indicating that the setting of whether or not to back up when deleting device information has been saved is popped up. The dialogue 3113 includes an OK button 3152 that the user can operate after confirming the message. This allows the user to transition to another screen.

[0111] In the information processing system according to this embodiment, for example, when the processes of steps S12 and S14, S19, and S21 described above are executed, other devices may exist between the communication terminal 3 and the server device 5. In other words, each piece of information (data) transmitted and received between the communication terminal 3 and the server device 5 may be configured to be transmitted and received once via another device (relay device, etc.). The above-mentioned configuration can be applied even when other processing steps exist between the communication terminal 3 and the server device 5.

[0112] <Processing including device information deletion input processing> Next, a process including the device information deletion input process will be described. Fig. 17A is a sequence diagram showing an example of a process including the device information deletion input process according to an embodiment. As shown in Fig. 17, the operation acceptance unit 32 of the communication terminal 3 accepts the start of a Web browser (step S31). Note that the process of step S31 is similar to step S11 described above, and therefore a detailed description thereof will be omitted.

[0113] The processing of the subsequent steps S32 to S34 is similar to the processing of steps S12 to S14 described above, and therefore detailed description thereof will be omitted. However, the screen data generated in step S33 is device environment setting task screen data, and the information transmitted to the communications terminal 3 in step S34 is the device environment setting task screen data.

[0114] Next, the display control unit 34 of the communication terminal 3 causes the display 307 of the communication terminal 3 to display a device environment setting task screen (step S35). The device environment setting task screen displayed in step S35 will be described later.

[0115] Next, the operation reception unit 32 receives an input for deleting device information as a task type (step S36). Specifically, the operation reception unit 32 receives the selection of the radio button for type: deleting device information (deleting device information) in the device environment setting task screen displayed on the display 307 in step S35.

[0116] Next, the operation receiving unit 32 receives a selection of a target device from the devices classified into the device information deletion target group (step S37). Specifically, the operation receiving unit 32 receives a selection of an item including address information of a device included in the device information deletion target group.

[0117] Next, the display control unit 34 displays a warning message for saving the task and a device information deletion confirmation screen on the display 307 of the communication terminal 3 (step S38). The device information deletion confirmation screen will be described later.

[0118] <Processing including pre-deletion backup setting processing> Next, a process including a pre-deletion backup setting process will be described. FIG. 17B is a sequence diagram showing an example of a process including a pre-deletion backup setting process according to the embodiment. The transmitting / receiving unit 31 of the communication terminal 3 transmits a confirmation result to the server device 5 (step S41). As a result, the transmitting / receiving unit 51 of the server device 5 receives the confirmation result transmitted by the communication terminal 3. At this time, the confirmation result includes a task ID for identifying the task input on the device information deletion confirmation screen displayed in the above-mentioned step S38, each input of "Yes" or "No" indicating the input confirmation result, and selected data. The selected data as an example of the confirmation result further includes various information stored in the information processing device 7 to be deleted.

[0119] Next, the judgment unit 55 of the server device judges whether or not a pre-deletion backup setting is necessary (step S42). Specifically, the judgment unit 55 searches the backup necessity setting management DB 5005 (see FIG. 10) using the task ID received in step S41 as a search key to read corresponding backup necessity information and judge whether or not a backup is necessary. In other words, the judgment unit 55 judges whether or not a setting is made to save information when the information is deleted.

[0120] If the server device 5 determines that the pre-deletion backup setting is "no" (if the setting to save information is not made), the server device 5 does not send an acquisition request to the information processing device 7, and the execution control unit 56 executes the processing of steps S48 to S53 described below (step S43).

[0121] On the other hand, if it is determined that the pre-deletion backup setting is "necessary" (if the setting is set to save information), the transmitting / receiving unit 51 transmits an acquisition request to the information processing device 7 (step S44). As a result, the transmitting / receiving unit 71 of the information processing device 7 receives the acquisition request transmitted by the server device 5. At this time, the acquisition request may include a target device ID that identifies the information processing device 7.

[0122] Next, the acquisition unit 73 of the information processing device 7 acquires device backup information (step S45). Specifically, the acquisition unit 73 reads and acquires the information of the information processing device 7 stored in a predetermined area of ​​the storage unit 7000 via the memory reading unit 79.

[0123] Next, the transmitting / receiving unit 71 transmits an acquisition response to the server device 5 as a response to the acquisition request received in step S44 (step S46). As a result, the transmitting / receiving unit 51 of the server device 5 receives the acquisition response transmitted by the information processing device 7. At this time, the acquisition response includes the device backup information associated with the device ID read in step S45.

[0124] Next, the setting registration unit 58 of the server device 5 registers the device backup information (step S47). Specifically, the setting registration unit 58 registers the device backup information received in step S46 in each item (serial number, etc.) of the device backup information associated with the device ID of the backup information management DB 5006 (see FIG. 11).

[0125] The above is an explanation of each process according to the result of the determination as to whether or not a pre-deletion backup setting is required.

[0126] Next, the transmitting / receiving unit 51 of the server device 5 transmits a deletion request to the information processing device 7 (step S48). As a result, the transmitting / receiving unit 71 of the information processing device 7 receives the deletion request transmitted by the server device 5.

[0127] There are two types of deletion requests: immediate deletion, in which deletion is performed immediately, and managed deletion, in which deletion is performed after schedule management. In managed deletion, the server device 5 transmits a deletion request to the information processing device 7 when it knows that the date and time for deletion has arrived. Here, in the case of managed deletion, the backup processing of steps S44 to S47 described above (from the request to obtain device backup information to registration) needs to be performed before the date and time for managed deletion.

[0128] Furthermore, in response to a deletion request transmitted from the server device 5, the information processing device 7 from which information is to be deleted is provided with an API (function) for deleting device information of its own device. Therefore, the transmitting / receiving unit 51 of the server device 5 can request the API from the information processing device 7 to delete desired information from the information processing device 7. On the other hand, if the information processing device 7 uses an API that specifies specific information, the server device 5 may transmit a deletion request specifying the information to be deleted to the information processing device 7.

[0129] The information processing device 7 may have an API (API1) for deleting information other than the network information, and then an API (API2) for deleting the network information. In this case, the server device 5 may first transmit a deletion request including API1 to the information processing device 7 to execute a series of processes related to deleting information other than the network information, and then transmit a deletion request including API2 to the information processing device 7 to execute a series of processes related to deleting the network information. In this way, the server device 5 can specify (transmit a deletion request to) the information processing device 7 to delete information for each unit grouped in the API. Here, a certain unit grouped in the API includes information divided by a setting unit such as app settings, other than the above-mentioned network information / network information.

[0130] Next, the execution processing unit 76 of the information processing device 7 executes the deletion of the device information by executing the task (step S49). Specifically, the execution processing unit 76 executes the deletion of the device information (e.g., account information, address information) stored in the information processing device 7 based on the API information received in step S48 by executing the task, and overwrites (or deletes) the contents of the corresponding items in the account information management DB 7001 (see FIG. 12) and the address information management DB 7002 (see FIG. 13) with the deletion execution results.

[0131] Next, the transmitting / receiving unit 71 transmits a deletion response to the server device 5 as a response to the deletion request received in step S48 (step S50). As a result, the transmitting / receiving unit 51 of the server device 5 receives the deletion response transmitted by the information processing device 7. At this time, if the information has been normally deleted in step S49, the deletion response includes deletion certificate data proving that the deletion has been executed.

[0132] Next, the acquisition unit 53 of the server device 5 acquires a deletion certificate (step S51). Specifically, the acquisition unit 53 acquires, via the transmission / reception unit 51, the deletion certificate data received in step S50.

[0133] Next, the transmitting / receiving unit 51 transmits the screen data to the communication terminal 3 (step S52). As a result, the transmitting / receiving unit 31 of the communication terminal 3 receives the screen data transmitted by the server device 5. At this time, the screen data includes the above-mentioned deletion certificate data.

[0134] Next, the display control unit 34 of the communication terminal 3 causes the display 307 of the communication terminal 3 to display the deletion certificate screen (step S53). Then, by performing the processes up to step S53, the sequence process related to the deletion of the information stored in the information processing device 7 is ended.

[0135] Through the processes described above, information stored in the information processing device 7 to be deleted is deleted. Below, examples of display screens displayed on the communication terminal 3 in the processes described above will be described.

[0136] ●Screen display example● FIG. 18 is a diagram showing an example of a device environment setting task screen according to the embodiment. This screen example is a screen display example executed in step S35 described above.

The device environment setting task screen 3114 is one of the screens in the item "Device Environment Setting Task" of the "Device Environment Setting" menu, and a screen related to a task of deleting device information is displayed as a device environment setting task. As details on the device environment setting task screen 3114, it is possible to input or select by radio button for items including name, description, and type. The device environment setting task screen 3114 shows a state in which the radio button for "Device Information Deletion" is selected as a type. This allows the user to select and input a setting for executing "Device Information Deletion" as a deletion type for the information processing device 7 to be deleted.

[0137] ●Screen display example● FIG. 19 is a diagram showing an example of a device type selection screen according to the embodiment. This screen example is a screen display example executed in step S37 described above. As shown in FIG. 19, a device type selection screen 3115 is displayed by the display control unit 34 on the display 307 of the communication terminal 3. The device type selection screen 3115 may be a screen that displays the same content as the device environment setting task screen 3114 shown in FIG. 18. In the device type selection screen 3115, a dialogue 3116 including the device address of the information processing device 7 is popped up. That is, the device type selection screen 3115 is an example of a screen that accepts an instruction to delete information stored in the information processing device 7 for each information processing device, and is an example of a screen that selects an information processing device to be deleted. Furthermore, it is an example of a screen that accepts the selection of the information processing device 7 to be deleted, which is an information processing device 7 from which information is deleted based on an instruction to delete information stored in the information processing device 7. The dialogue 3116 includes an OK button 3153 and a cancel button 3154 that can be operated by the user after selecting the device type of the information processing device 7. This allows the user to select the information processing device 7 to be deleted and reflect it. Specifically, in step S44, the transmitting / receiving unit 51 of the server device 5 transmits an acquisition request based on the device ID of the information processing device selected on the device type selection screen 3115.

[0138] ●Screen display example● FIG. 20 is a diagram showing an example of a device information deletion confirmation screen according to the embodiment.

Note that the dialogue 3118 includes a Yes button 3155 and a No button 3156. This allows the user to determine whether or not to save the task of deleting information. That is, the device information deletion confirmation screen 3117 is an example of a screen for accepting an instruction to delete information stored in the information processing device 7 to be deleted. In this way, the device information deletion confirmation screen 3117 is a screen for accepting an instruction to delete information stored in the selected information processing device 7 after the information processing device 7 to be deleted is selected on the above-mentioned device type selection screen 3115. Note that the device type selection screen 3115 for selecting the information processing device 7 to be deleted and the device information deletion confirmation screen 3117 for accepting an instruction to delete information may be either one screen (the same screen).

[0139] ●Screen display example● FIG. 21 is a diagram showing an example of a deletion certificate display instruction screen according to the embodiment. This screen example is a screen display example executed in step S53 described above. As shown in FIG. 21, a deletion certificate display instruction screen 3119 is displayed by the display control unit 34 on the display 307 of the communication terminal 3. The deletion certificate display instruction screen 3119 is one of the screens in the item "Device Environment Setting Task" of the "Device Environment Setting" menu, and displays a screen related to a task for deleting device information as a device environment setting task. The deletion certificate display instruction screen 3119 displays each item including a template name (task type) showing a task log and its detailed results, a start date, an end date, a model name, an address, a serial number, a function, a function detail, a result, a reason, and the like. The deletion certificate display instruction screen 3119 further displays a PDF button 3157. This allows the user to operate the PDF button 3157 to display the PDF data of the deletion certificate.

[0140] ●Screen display example● Fig. 22 is a diagram showing an example of a device information deletion certificate screen according to the embodiment. This screen example is a screen displayed by operating the PDF button 3157 displayed on the above-mentioned deletion certificate display instruction screen 3119. As shown in Fig. 22, a device information deletion certificate 3120 is displayed on the display 307 of the communication terminal 3 by the display control unit 34. The device information deletion certificate 3120 displays the serial number, model name, and deletion date and time of the information processing device 7 that has been deleted, but this is merely an example and is not limited to these. This allows the user to grasp and confirm the details of what kind of device the information processing device 7 that has been deleted was.

[0141] ●Management status after deleting the account information management table● Fig. 23 is a conceptual diagram showing an example of the account information management table according to the embodiment after information has been deleted. The state shown is one in which the information managed in the account information management DB 7001 managed by the information processing device 7 has been deleted by the process of step S49 described above.

That is, Fig. 24 shows a state in which other account IDs are represented by "···", and each item associated with those account IDs is also displayed by "···".

[0143] In the information processing system according to this embodiment, for example, when the processes of steps S44 and S46, and steps S48 and S50 described above are executed, other devices may exist between the server device 5 and the information processing device 7. In other words, each piece of information (data) transmitted and received between the server device 5 and the information processing device 7 may be configured to be transmitted and received once via another device (relay device, etc.). The above-mentioned configuration can be applied even when other processing steps exist between the server device 5 and the information processing device 7.

[0144] <Restoration process for deleted information> Next, a process of restoring deleted information will be described with reference to Fig. 25A, which is a sequence diagram showing an example of a process including a device information restoring task selection process according to an embodiment.

[0145] First, the operation acceptance unit 32 of the communication terminal 3 accepts the start of a Web browser (step S61). Note that the process of step S61 is similar to the above-mentioned step S11 (S31), and therefore a detailed description thereof will be omitted.

[0146] The subsequent processing of steps S62 to S64 is similar to the processing of steps S12 (S32) to S14 (S34) described above, and therefore detailed description thereof will be omitted. However, the screen data generated in step S63 and the data transmitted to the communication terminal 3 in step S64 are device information restoration task creation screen data related to a screen for creating a device information restoration task. At this time, the information included in the screen data acquisition request transmitted to the server device 5 in step S62 is information for generating the device information restoration task creation screen data.

[0147] Next, the display control unit 34 of the communication terminal 3 causes the display 307 of the communication terminal 3 to display a device information restoration task creation screen (step S65). The device environment setting task screen displayed in step S35 will be described later.

[0148] Next, the operation acceptance unit 32 accepts a selection input on the device information restoration task creation screen (step S66). Specifically, the operation acceptance unit 32 accepts the selection of the radio button for Type: Device Information Restoration (Device Information Restoration) on the device information restoration task creation screen displayed on the display 307 in step S65.

[0149] The subsequent processing of steps S67 to S69 is similar to the processing of steps S62 to S64 described above, and therefore detailed description thereof will be omitted. However, the screen data generated in step S68 and the data transmitted to the communication terminal 3 in step S69 are restore target device selection screen data relating to a screen for selecting a restore target device. At this time, the information included in the screen data acquisition request transmitted to the server device 5 in step S67 is information for generating the restore target device selection screen data.

[0150] Next, the display control unit 34 of the communication terminal 3 displays a restoration target device selection screen on the display 307 of the communication terminal 3 (step S70). The restoration target device selection screen displayed in step S70 will be described later.

[0151] Next, the operation reception unit 32 receives a selection input on the restore target device selection screen (step S71). Specifically, the operation reception unit 32 receives a selection input of desired information displayed in the dialog of "Type: Device Backup Information" in the restore target device selection screen displayed on the display 307 in step S70.

[0152] FIG. 25B is a sequence diagram showing an example of processing including a post-restoration backup information deletion necessity setting process according to the embodiment.

[0153] The processing of steps S81 to S83 is similar to the processing of steps S67 to S69 described above, and therefore detailed description thereof will be omitted. However, the screen data generated in step S82 and the data transmitted to the communication terminal 3 in step S83 are post-restoration backup information deletion necessity setting screen data relating to a screen for setting whether or not backup information needs to be deleted after restoration is performed. At this time, the information included in the screen data acquisition request transmitted to the server device 5 in step S81 is information for generating post-restoration backup information deletion necessity setting screen data.

[0154] Next, the display control unit 34 of the communication terminal 3 displays a post-restoration backup information deletion necessity setting screen on the display 307 of the communication terminal 3 (step S84). The post-restoration backup information deletion necessity setting screen displayed in step S84 will be described later.

[0155] Next, the operation reception unit 32 receives a selection input on the backup information deletion necessity setting screen after restoration execution (step S85). Specifically, the operation reception unit 32 receives various inputs including an input to a save button in the backup information deletion necessity setting screen after restoration execution displayed on the display 307 in step S84.

[0156] Next, the transmitting / receiving unit 31 transmits a setting request to the server device 5 (step S86). As a result, the transmitting / receiving unit 51 of the server device 5 receives the setting request transmitted by the communication terminal 3. At this time, the setting request includes device information restoration information, restoration target device information, post-restoration backup information, and save button information as the input / selection data input in steps S66, S71, and S85. Note that the process of step S86 may be separately executed after the process of step S66, the process of step S71, and the process of step S85 described above.

[0157] Next, the setting registration unit 58 of the server device 5 sets (registers) the device information restoration (step S87). Specifically, the setting registration unit 58 stores the device information restoration information related to the setting of the device information restoration received in step S86 in a predetermined area of ​​the memory unit 5000 of the server device 5 via the memory readout unit 59. Note that the setting registration unit 58 may store the device information restoration information in a dedicated data table instead of in the predetermined area of ​​the memory unit 5000.

[0158] Next, the setting registration unit 58 sets (registers) the restoration target device information (step S88). Specifically, the setting registration unit 58 stores the restoration target device information related to the settings of the restoration target device received in step S86 in a predetermined area of ​​the storage unit 5000 of the server device 5 via the storage reading unit 59. Note that the setting registration unit 58 may store the restoration target device information in a dedicated data table instead of in the predetermined area of ​​the storage unit 5000.

[0159] Next, the setting registration unit 58 sets (registers) the post-restoration backup information (step S89). Specifically, the setting registration unit 58 stores the post-restoration backup information relating to the post-restoration backup settings received in step S86 in a predetermined area of ​​the memory unit 5000 of the server device 5 via the memory readout unit 59. Note that the setting registration unit 58 may store the post-restoration backup information in a dedicated data table instead of in a predetermined area of ​​the memory unit 5000.

[0160] After the process of step S89, the transmitting / receiving unit 51 of the server device 5 may transmit to the communication terminal 3 a setting response as a response to the setting request executed in step S86.

[0161] Next, a process according to the presence or absence of a restore task will be described. Fig. 25C is a sequence diagram showing an example of a process including a restore task presence determination process according to the embodiment.

[0162] The determination unit 55 of the server device 5 determines whether or not there is a restoration task (step S91). Specifically, the determination unit 55 reads information stored in each predetermined area of ​​the storage unit 5000 of the server device 5 via the storage reading unit 59, and determines whether or not the information related to the device information restoration stored in the processes of steps S87 to S89 described above has been set (registered).

[0163] If it is determined that there is no restoration task, the execution control unit 56 ends the process related to restoration and exits this sequence (step S92).

[0164] On the other hand, if it is determined that a restoration task is "present," the acquisition unit 53 acquires device backup information of the target device (step S93). Specifically, the acquisition unit 53 searches the backup information management DB 5006 using, for example, the serial number, which is an example of the restoration target device information, as a search key from the information read out in step S91 via the storage reading unit 59, to read out the corresponding device backup information (serial number).

[0165] Next, the transmitting / receiving unit 51 transmits a device information restoration task execution request to the information processing device 7 (step S94). As a result, the transmitting / receiving unit 71 of the information processing device 7 receives the device information restoration task execution request transmitted by the server device 5. At this time, the device information restoration task execution request includes the serial number, account name, account password, name, email address, etc., as the device backup information read out in step S93.

[0166] Next, the registration management unit 78 of the information processing device 7 restores (registers) the device backup information (step S95). Specifically, the registration management unit 78 restores (registers) the account name, account password, name, and email address, for example, of the device backup information received in step S94, to the corresponding items of the account information management DB 7001 (see FIG. 12) and the address information management DB 7002 (see FIG. 13) via the storage and reading unit 79.

[0167] Next, the transmitting / receiving unit 71 transmits a device information restoration task execution response as a response to the device information restoration task execution request to the server device 5 (step S96). As a result, the transmitting / receiving unit 51 of the server device 5 receives the device information restoration task execution response transmitted by the information processing device 7. At this time, the device information restoration task execution response includes restoration execution result information relating to the restoration execution result.

[0168] Next, the transmitting / receiving unit 51 of the server device 5 transmits a device information restoration task display request to the communications terminal 3 (step S97). As a result, the transmitting / receiving unit 31 of the communications terminal 3 receives the device information restoration task display request transmitted by the server device 5. At this time, the device information restoration task display request includes restoration execution result screen data based on the restoration execution result information received by the server device 5 from the information processing device 7 in step S96.

[0169] Next, the display control unit 34 of the communication terminal 3 causes a device information restoration task execution result screen to be displayed on the display 307 of the communication terminal 3 (step S98).

[0170] 25D is a sequence diagram showing an example of a process including a maintenance process or a deletion process of backup information according to the embodiment. The determination unit 55 of the server device 5 determines whether to leave the backup information (step S101). Specifically, the determination unit 55 reads information related to the post-restoration backup information deletion necessity setting as the post-restoration backup information selected by the user in step S84 and set (registered) in step S89 from a predetermined area of ​​the storage unit 5000 via the storage readout unit 59, and makes a determination.

[0171] When it is determined that the backup information needs to be maintained (kept), the setting registration unit 58 maintains the device backup information of the target device (step S102). Specifically, the setting registration unit 58 maintains the information stored in the backup information management DB 5006 (see FIG. 11).

[0172] On the other hand, if it is determined that the backup information needs to be maintained (kept), the setting registration unit 58 deletes the device backup information of the target device (step S103). Specifically, the setting registration unit 58 deletes information that is to be deleted from among the information stored in the backup information management DB 5006 (see FIG. 11).

[0173] The processes in steps S101 to S103 and the processes in steps S97 and S98 described above may be executed asynchronously with each other, so that either process may be executed first.

[0174] Then, by carrying out the processes of steps S91 to S103, the sequence process relating to the restoration after the deletion of the information of the information processing device 7 to be deleted is completed.

[0175] ●Screen display example● FIG. 26 is a diagram showing an example of a device information restoration task creation screen according to the embodiment. This screen example is a screen display example executed in step S65 described above.
