[0008] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0009] 1 is a diagram showing an example of the configuration of an information processing system according to one embodiment of the present invention. The information processing system 100 according to this embodiment is an information processing system that performs inventory work on one or more managed terminal devices (managed terminal devices) and supports terminal device management operations. The information processing system 100 according to this embodiment includes an administrator terminal device 101, a server device 102, one or more managed terminal devices 103, and one or more user terminal devices 104.

[0010] The administrator terminal device 101, the server device 102, the managed terminal device 103, and the user terminal device 104 are connected via a network NW so as to be able to transmit and receive information to and from each other. Here, the network NW is not a public network, but a communication network that can be used only by limited information processing devices (users), a so-called closed network. In other words, the administrator terminal device 101, the server device 102, the managed terminal device 103, and the user terminal device 104 are connected to a closed network that is configured separately from a public network such as the Internet. Note that the transmission and reception of information between the administrator terminal device 101 and the server device 102, and the transmission and reception of information between the administrator terminal device 101 and the user terminal device 104 may be performed via a public network.

[0011] The administrator terminal device 101 is a terminal device that manages inventory work for the managed terminal device 103. For example, the administrator terminal device 101 issues a confirmation request to confirm the presence or absence of the managed terminal device 103 based on instructions from a user who is a system administrator. Hereinafter, the confirmation request to confirm the presence or absence of the managed terminal device 103 is also referred to as a "confirmation request for the managed terminal device 103." Also, for example, the administrator terminal device 101 holds a management ledger file related to the managed terminal device 103, and updates the information in the management ledger file based on an access log (log information) acquired from the server device 102. Also, for example, the administrator terminal device 101 may analyze the progress of the inventory work by referring to the management ledger file.

[0012] The server device 102 is a server device that receives access from the managed terminal device 103 during an inventory operation for the managed terminal device 103. For example, the server device 102 provides a web page for checking the presence or absence of the managed terminal device 103, detects access to the web page, and records information about the accessed managed terminal device 103 in an access log. Also, for example, the server device 102 provides the recorded access log to the administrator terminal device 101 in response to a request from the administrator terminal device 101.

[0013] The managed terminal device 103 is a terminal device that is the target of an inventory operation, and in this embodiment, it is assumed to be a smartphone as an example. For example, the managed terminal device 103 accesses the server device 102 based on a confirmation request from the administrator terminal device 101. In this embodiment, the managed terminal device 103 is a device that communicates via a closed network NW, and is assigned a fixed IP address, which is a fixed identifier that can be uniquely identified within the closed network. That is, a different fixed IP address is assigned to each managed terminal device 103, and the managed terminal device 103 and the fixed IP address are associated one-to-one. One managed terminal device 103 can be identified by the assigned fixed IP address. The fixed IP address assigned to the managed terminal device 103 is an example of a terminal device identifier or address information. Note that the managed terminal device 103 is not limited to a smartphone, and this embodiment can be applied to devices with communication functions such as tablet terminals and PCs (personal computers). In a public network, the IP addresses assigned to terminal devices are generally not fixed IP addresses but are randomly assigned from available IP addresses. Since a terminal device cannot be identified from such a randomly assigned IP address, a general terminal device in a public network that is not assigned a fixed IP address is not a terminal device to be managed in this embodiment.

[0014] The user terminal device 104 is a terminal device through which a legitimate user of the managed terminal device 103 receives a request for verification of the managed terminal device 103 from the administrator terminal device 101 .

[0015] 2 is a diagram showing an example of the hardware configuration of an information processing device 200 that can be used as various devices (e.g., the administrator terminal device 101, the server device 102, the managed terminal device 103, and the user terminal device 104) that make up the information processing system 100 in this embodiment shown in FIG. 1. The information processing device 200 has a CPU 201, a ROM 202, a RAM 203, an auxiliary storage device 204, and a network I / F 207. The information processing device 200 may also have at least one of an output device 205 and an input device 206. The CPU 201, the ROM 202, the RAM 203, the auxiliary storage device 204, the output device 205, the input device 206, and the network I / F 207 are communicably connected via a system bus 208.

[0016] The CPU (Central Processing Unit) 201 is a central processing unit that controls various operations of the information processing device 200. For example, the CPU 201 may control the operation of the entire information processing device 200. The ROM (Read Only Memory) 202 stores control programs, boot programs, etc. that can be executed by the CPU 201. The RAM (Random Access Memory) 203 is the main storage memory of the CPU 201, and is used as a work area or a temporary storage area for expanding various programs.

[0017] The auxiliary storage device 204 stores various data and programs. The auxiliary storage device 204 is realized by a storage device capable of temporarily or permanently storing various data, such as a non-volatile memory such as a hard disk drive (HDD) or a solid state drive (SSD).

[0018] The output device 205 is a device that outputs various types of information and is used to present various types of information to a user. For example, the output device 205 is realized by a display device such as a display. The output device 205 may present information to a user by displaying various types of display information. As another example, the output device 205 may be realized by an audio output device that outputs sounds such as voices and electronic sounds. In this case, the output device 205 may present information to a user by outputting sounds such as voices and electronic sounds. Furthermore, the device used as the output device 205 may be changed as appropriate depending on the medium used to present information to a user.

[0019] The input device 206 is used to receive various instructions from a user. For example, the input device 206 may include an input device such as a mouse, a keyboard, or a touch panel. As another example, the input device 206 may include a sound collection device such as a microphone to collect voices uttered by the user. In this case, various analytical processes such as acoustic analysis and natural language processing may be performed on the collected voice, and the content of the voice may be recognized as an instruction from the user. As another example, the input device 206 may include an imaging device such as a camera to capture an image. The device used as the input device 206 may be changed as appropriate depending on the method for recognizing instructions from the user. Multiple types of devices may be used as the input device 206.

[0020] The network I / F 207 is used for communication with external devices via a network. The device used as the network I / F 207 may be changed as appropriate depending on the type of communication path and the communication method used.

[0021] The CPU 201 loads a program stored in the ROM 202 or the auxiliary storage device 204 into the RAM 203 and executes this program, thereby realizing the functions of the devices shown in Fig. 3 and the processes shown in Fig. 5. The program for the information processing device 200 may be provided to the information processing device 200 by a recording medium such as a CD-ROM, or may be downloaded via a network, etc. When the program for the information processing device 200 is provided by a recording medium, the program recorded on the recording medium is installed in the auxiliary storage device 204 by inserting the recording medium into a predetermined drive device.

[0022] 2 is merely an example and does not necessarily limit the hardware configuration of the information processing device that constitutes the information processing system 100 in this embodiment. As a specific example, some components such as the input device 206 and the output device 205 may not be included. As another example, components according to the functions realized by the information processing device 200 may be added as appropriate.

[0023] Fig. 3 is a diagram showing an example of the functional configuration of the information processing system 100 according to this embodiment. In Fig. 3, the same components as those shown in Fig. 1 are denoted by the same reference numerals.

[0024] The following describes the administrator terminal device 101. The administrator terminal device 101 includes a communication unit 311, a control unit 312, an input / output control unit 313, an issuing unit 314, an acquiring unit 315, a management unit 316, an analyzing unit 317, and a storage unit 318.

[0025] The communication unit 311 is a communication interface that enables each component of the administrator terminal device 101 to transmit and receive information to and from other devices (e.g., the server device 102, the managed terminal device 103, and the user terminal device 104) via the network NW. The communication unit 311 can be realized, for example, by the network I / F 207. In the following description, when each component of the administrator terminal device 101 transmits and receives information to and from other devices, it is assumed that the transmission and reception of the information is performed via the communication unit 311 unless otherwise specified.

[0026] The control unit 312 is responsible for controlling each component of the administrator terminal device 101. The input / output control unit 313 executes various processes related to presenting various types of information to the user and accepting information input (e.g., instructions, etc.) from the user. For example, the input / output control unit 313 may execute processes related to presenting a UI (User Interface) and accepting input via the UI. This enables the administrator terminal device 101 to recognize instructions from the user and present the results of processing in accordance with those instructions to the user.

[0027] The issuing unit 314 issues a confirmation request to confirm the presence or absence of a managed terminal device 103 in an inventory operation regarding the managed terminal device 103. The issuing unit 314 issues a confirmation request to each managed terminal device 103, including access destination information to be accessed in order to confirm the managed terminal device 103. The access destination information is, for example, a URL (Uniform Resource Locator) of a web page provided by the server device 102 in order to confirm the managed terminal device 103.

[0028] The acquisition unit 315 requests an access log (log information) from the server device 102 and acquires the access log from the server device 102. This access log records information (including the access date and time, fixed IP address, etc.) of the managed terminal device 103 that accessed the server device 102 to check whether the managed terminal device 103 exists.

[0029] The management unit 316 manages the management ledger file related to the managed terminal device 103 stored in the storage unit 318. For example, the management unit 316 updates the information in the management ledger file based on the access log of the server device 102 acquired by the acquisition unit 315 and stores the updated information in the storage unit 318. Specifically, the management unit 316 extracts a fixed IP address from the access log of the server device 102 acquired by the acquisition unit 315, and updates the information in the management ledger file to information indicating that confirmation has been completed for the managed terminal device 103 corresponding to the fixed IP address.

[0030] The analysis unit 317 analyzes the management ledger file related to the managed terminal device 103 stored in the storage unit 318 and outputs the analysis result. For example, the analysis unit 317 analyzes the management ledger file and generates a progress status file indicating the progress status of inventory work related to the managed terminal device 103.

[0031] The storage unit 318 schematically shows a storage area for storing various data, various programs, etc. For example, the storage unit 318 may store data and programs for each component of the administrator terminal device 101 to execute processing. The storage unit 318 may also store a management ledger file related to the managed terminal device 103, or a progress status file indicating the progress status of inventory work, etc.

[0032] Next, a description will be given of the server device 102. The server device 102 includes a communication unit 321, a control unit 322, an input / output control unit 323, a reception unit 324, a recording unit 325, and a storage unit 326.

[0033] The communication unit 321 is a communication interface that allows each component of the server device 102 to send and receive information to and from other devices (e.g., the administrator terminal device 101, the managed terminal device 103, and the user terminal device 104) via the network NW. The communication unit 321 can be realized, for example, by the network I / F 207. In the following description, when each component of the server device 102 sends and receives information to and from other devices, it is assumed that the information is sent and received via the communication unit 321 unless otherwise specified.

[0034] The control unit 322 is responsible for controlling each component of the server device 102. The input / output control unit 323 executes various processes related to presenting various information to the user and accepting information input (e.g., instructions, etc.) from the user. For example, the input / output control unit 323 may execute processes related to presenting a UI via another device and processes related to accepting input via the UI. This enables the server device 102 to recognize instructions from the user and present the results of processing in accordance with those instructions to the user.

[0035] The reception unit 324 receives access from the managed terminal device 103 during an inventory operation for the managed terminal device 103. For example, the reception unit 324 receives access from the managed terminal device 103 in response to a confirmation request from the administrator terminal device 101 to a web page for confirming the managed terminal device 103.

[0036] The recording unit 325 acquires the IP address of the managed terminal device 103 whose access has been accepted by the accepting unit 324, and records the date and time of the access and the acquired IP address in the access log.

[0037] The storage unit 326 schematically shows a storage area for storing various data, various programs, etc. For example, the storage unit 326 may store data and programs for executing processes by each component of the server device 102. The storage unit 326 may also store an access log related to accesses from the managed terminal device 103.

[0038] Next, a description will be given of the managed terminal device 103. The managed terminal device 103 includes a communication unit 331, a control unit 332, an input / output control unit 333, an imaging unit 334, and a storage unit 335.

[0039] The communication unit 331 is a communication interface that enables each component of the managed terminal device 103 to send and receive information to and from other devices (e.g., the administrator terminal device 101, the server device 102, and the user terminal device 104) via the network NW. The communication unit 331 can be realized, for example, by the network I / F 207. In the following description, when each component of the managed terminal device 103 sends and receives information to and from other devices, it is assumed that the information is sent and received via the communication unit 331 unless otherwise specified.

[0040] The control unit 332 is responsible for controlling each component of the managed terminal device 103. The input / output control unit 333 executes various processes related to presenting various types of information to the user and accepting information input (e.g., instructions) from the user. For example, the input / output control unit 333 may execute processes related to presenting a UI and accepting input via a UI. This enables the managed terminal device 103 to recognize instructions from the user and present the user with the results of processing in accordance with those instructions.

[0041] The imaging unit 334 includes an imaging device such as a camera, and captures an image by capturing an image. For example, when access destination information is provided using a two-dimensional code (e.g., a QR code (registered trademark)) in the confirmation request of the managed terminal device 103, the imaging unit 334 captures the two-dimensional code to capture an image. Also, for example, the imaging unit 334 may capture and capture an image related to reading a URL using an application in order to acquire access destination information in the confirmation request of the managed terminal device 103.

[0042] The storage unit 335 schematically shows a storage area for storing various data, various programs, etc. For example, the storage unit 335 may store data and programs for each component of the managed terminal device 103 to execute processing.

[0043] Next, a description will be given of the user terminal device 104. The user terminal device 104 includes a communication unit 341, a control unit 342, an input / output control unit 343, and a storage unit 344.

[0044] The communication unit 341 is a communication interface that allows each component of the user terminal device 104 to send and receive information to and from other devices (e.g., the administrator terminal device 101, the server device 102, and the managed terminal device 103, etc.) via the network NW. The communication unit 341 can be realized, for example, by the network I / F 207. In the following description, when each component of the user terminal device 104 sends and receives information to and from other devices, it is assumed that the information is sent and received via the communication unit 341 unless otherwise specified.

[0045] The control unit 342 is responsible for controlling each component of the user terminal device 104. The input / output control unit 343 executes various processes related to presenting various information to the user and accepting information input (e.g., instructions, etc.) from the user. For example, the input / output control unit 343 may execute processes related to presenting a UI and accepting input via the UI. This enables the user terminal device 104 to recognize instructions from the user and present the results of processing in accordance with those instructions to the user.

[0046] The storage unit 344 schematically shows a storage area for storing various data, various programs, etc. For example, the storage unit 344 may store data and programs for each component of the user terminal device 104 to execute processing.

[0047] FIG. 4 is a diagram illustrating a management ledger file related to the managed terminal device 103. This management ledger file is held, for example, in the administrator terminal device 101. As shown in FIG. 4, the management ledger file manages, as information related to the managed terminal device 103, the terminal management number of the managed terminal device 103 and the IP address (fixed IP address within a closed network) assigned to the managed terminal device 103. The management ledger file also manages the department and user name using the managed terminal device 103, and the user's email address. The management ledger file also manages, as information indicating the status of inventory work, the date on which a request to confirm the presence or absence of the managed terminal device 103 was made and the date on which the confirmation was completed. Therefore, if the date on which a request to confirm the presence or absence of the managed terminal device 103 was made is recorded but the date on which the confirmation was completed is not recorded, it can be determined that the managed terminal device 103 has not been confirmed in the inventory work. This information is managed for each managed terminal device 103. 4, the date on which a confirmation request was made and the date on which confirmation was completed are managed as information indicating the status of the inventory work, but the status of the inventory work may be managed using something like a flag indicating whether a confirmation request was made by the managed terminal device 103 and whether confirmation was completed. Also, the example shown in FIG. 4 is just one example, and the present invention is not limited to this, and other information may also be managed in the management ledger file.

[0048] Next, a process relating to an inventory of the managed terminal device 103 in the information processing system of this embodiment will be described with reference to Fig. 5. Fig. 5 is a diagram for explaining a process example of the information processing system of this embodiment.

[0049] When an inventory operation for the managed terminal device 103 is started, the administrator terminal device 101 issues a confirmation request for the managed terminal device 103 via the issuing unit 314 (501), the confirmation request including access destination information for the managed terminal device 103 to be accessed in order to confirm the managed terminal device 103. For example, the administrator terminal device 101 requests the confirmation of the managed terminal device 103 by sending a request email or the like to the user terminal device 104, with a QR code attached that indicates the access destination information, as illustrated as 601 in FIG. 6(A). By sending the confirmation request for the managed terminal device 103 including the access destination information to a terminal device other than the managed terminal device 103 in this way, for example, if the managed terminal device 103 is owned by a person other than the authorized user, the confirmation in the inventory operation cannot be completed, thereby enhancing security. Note that the administrator terminal device 101 may request the confirmation of the managed terminal device 103 by sending a request email or the like to the managed terminal device 103, with a URL of the access destination included as a link, as illustrated as 602 in FIG. 6(B). Furthermore, the present invention is not limited to these, and other methods may be applied as long as they can present access destination information for checking the terminal device 103 to be managed to the user.

[0050] In the following description, it is assumed that the access destination information for checking the managed terminal device 103 is represented by a QR code. When a confirmation request for the managed terminal device 103 issued by the administrator terminal device 101 is received, the user of the managed terminal device 103 photographs the QR code attached to the confirmation request using the managed terminal device 103. As a result, the managed terminal device 103 acquires an image of the QR code using the imaging unit 334. Then, the managed terminal device 103 acquires access destination information (the URL of a web page provided by the server device 102 for confirming the managed terminal device 103) from the acquired image of the QR code (502).

[0051] Next, the terminal device 103 to be managed accesses a web page of the server device 102 for confirming the terminal device 103 to be managed, which is the access destination, based on the acquired access destination information (503).

[0052] When the server device 102 receives, via the receiving unit 324, access from the managed terminal device 103 to a Web page for checking the managed terminal device 103, the recording unit 325 acquires the IP address of the managed terminal device 103 and records it in the access log (504). Fig. 7 is a diagram illustrating the access log of the server device 102. As shown in Fig. 7, the access log 701 records the date and time when the Web page for checking the managed terminal device 103 was accessed and the IP address 702 of the managed terminal device 103 that made the access.

[0053] Next, the server device 102 notifies the accessed terminal device 103 that confirmation of the terminal device 103 has been completed (505). In this way, the IP addresses of the terminal devices 103 to be managed that have accessed the server device 102 in response to a request from the administrator terminal device 101 to confirm the terminal devices 103 to be managed are recorded in the access log of the server device 102 .

[0054] Thereafter, the administrator terminal device 101 requests the access log from the server device 102 via the acquisition unit 315 based on instructions from the user who will be the system administrator (506). In response to this request, the server device 102 transmits to the administrator terminal device 101 an access log in which the IP addresses of the managed terminal devices 103 that accessed the server device 102 are recorded (507). As a result, the administrator terminal device 101 acquires the access log of the server device 102. Note that while the acquisition of the access log of the server device 102 is performed based on instructions from the user, the present invention is not limited to this, and for example, the administrator terminal device 101 may automatically perform the acquisition at a predetermined timing (every few hours, every day, etc.).

[0055] The administrator terminal device 101, which has acquired the access log of the server device 102, extracts the IP address from the acquired access log using the management unit 316 (508). The administrator terminal device 101 then updates and saves the information in the management ledger file based on the IP address extracted from the access log by the management unit 316 (509). Specifically, the administrator terminal device 101 compares the IP address extracted from the access log with the IP addresses managed in the management ledger file, and updates the information to indicate that confirmation has been completed for the managed terminal device 103 to which an IP address matching the IP address extracted from the access log is assigned. The administrator terminal device 101 may also generate and save a progress status file that indicates the progress of inventory work for the managed terminal device 103 based on the information in the management ledger file.

[0056] 8 is a diagram showing an example of an output of the progress status of inventory work obtained by analyzing the management ledger file. The analysis unit 317 of the administrator terminal device 101 may, for example, analyze the progress status of inventory work for the entire target or the progress status of inventory work for each department from the information in the management ledger file, and present the results to the system administrator, user, etc. by displaying a graph as shown in display example 801. By outputting the analysis results of the progress status of inventory work, etc., it becomes possible to easily grasp the progress status of the entire target or each department. For example, it is possible to urge departments that are behind in inventory work to carry out their work promptly, or to raise awareness of the need to carry out inventory work by comparing with other departments.

[0057] As described above, according to this embodiment, a confirmation request is issued to the managed terminal device 103, and the presence or absence of the managed terminal device 103 is confirmed based on a record of access from the managed terminal device 103 in response to the confirmation request. This makes it possible to reliably confirm the presence or absence of the managed terminal device 103 in an inventory work related to the managed terminal device 103. Furthermore, the administrator terminal device 101 updates the information in the management ledger file based on the IP address of the managed terminal device 103 extracted from the access log of the server device 102, thereby reducing the workload involved in the inventory work related to the managed terminal device 103. For example, an inventory work related to the managed terminal device 103 can be performed without the need for an operator to input responses from users or to actually check the items, thereby reducing the workload and time involved in the confirmation work and reducing the workload.

[0058] In the above explanation, an example has been described in which the server device 102 accepts access from the managed terminal device 103 in response to a confirmation request, records the IP address of the managed terminal device 103 in an access log, and the administrator terminal device 101 acquires the access log from the server device 102 and updates the information in the management ledger file. However, this is not limited to this, and the server device 102 may hold information in the management ledger file and update the information in the management ledger file based on the recorded access log. In this case, the server device 102 may also analyze the management ledger file. The server device 102 may then provide the administrator terminal device 101 with information on the updated management file and the analysis results of the management ledger file.
