[0001] The present disclosure relates to an information processing device, an information processing method, and an information processing program.

[0002] Conventionally, when capturing images using a camera mounted on a vehicle, there exists a recording device that takes into consideration the privacy of people in storage-prohibited areas. After the vehicle passes through an area where storage of video is prohibited in advance (storage-prohibited area), the recording device performs control to prohibit the storage of video if no incident or accident has occurred in the storage-prohibited area (see Patent Document 1).

[0003] Japanese Patent Application Laid-Open No. 2021-118499

[0004] Incidentally, at various organizational bases such as corporate offices and factories, photography may be prohibited in order to prevent the leakage of confidential information, etc. This photography prohibition may be uniform regardless of events such as incidents and accidents. The recording device described in Patent Document 1 is designed to save footage when an incident or accident occurs, but is not able to cope with a uniform photography prohibition.

[0005] The present disclosure provides an information processing device, an information processing method, and an information processing program that take security into consideration in a predetermined area.

[0006] An information processing device of one embodiment includes a memory unit that stores photography-prohibited area information regarding photography-prohibited areas, a first acquisition unit that acquires self-location information regarding the self-location of a terminal equipped with a camera from the terminal, a first determination unit that determines whether the self-location is within the photography-prohibited area based on the photography-prohibited area information stored in the memory unit and the self-location information acquired by the first acquisition unit, and an operation control unit that controls the terminal to perform a predetermined operation when the first determination unit determines that the self-location is within the photography-prohibited area.

[0007] The information processing device, information processing method, and information processing program disclosed herein can take security into consideration in areas where photography is prohibited (prescribed areas).

[0008] It is a diagram for explaining an overview of an information processing apparatus according to an embodiment. It is a block diagram for explaining an information processing apparatus according to an embodiment. It is a flowchart for explaining an information processing method according to an embodiment.

[0009] An embodiment will be described below.

[0010] [Outline of Information Processing Apparatus 100] First, an outline of an information processing apparatus 100 according to an embodiment will be described. Fig. 1 is a diagram for explaining an outline of an information processing apparatus 100 according to an embodiment.

[0011] The information processing device 100 may be configured, for example, as a deletion device that deletes images captured in a photography-prohibited area 210 (predetermined area) in consideration of security in the photography-prohibited area 210 (predetermined area). The information processing device 100 may also be configured as an activation prohibition device that prohibits activation of the camera 311 in the photography-prohibited area 210 (predetermined area). The information processing device 100 is not limited to the above-described exemplary device, and may constitute various other devices. The information processing device disclosed herein will create a foundation for industry and technological innovation and can contribute to the achievement of Goal 9 of the Sustainable Development Goals (SDGs). The information processing device 100 may be, for example, a computer such as a server, desktop, laptop, tablet, or smartphone.

[0012] The terminal 300 includes a camera 311. The terminal 300 may be a mobile terminal that can be moved, a portable terminal that can be carried, or the like. As a specific example, the terminal 300 may be a smartphone, a tablet, a laptop, a mirrorless camera, a single-lens camera, or the like. The terminal 300 is also capable of acquiring its own position (self-position). As an example, the terminal 300 acquires its own position information (self-position information) using GNSS, GPS, or the like.

[0013] The information processing device 100 may be arranged in, for example, a base station 200 that communicates with the terminal 300. The information processing device 100 stores information on a preset photography prohibited area 210 (photography prohibited area information).

[0014] The information processing device 100 acquires self-location information from the terminal 300. The information processing device 100 determines whether the self-location of the terminal 300 is within the photography-prohibited area 210 based on the photography-prohibited area information and the self-location information.

[0015] When the information processing device 100 determines that the self-location of the terminal 300 is within the photography-prohibited area 210, it controls the terminal 300 to perform a predetermined operation. As an example, when the self-location of the terminal 300 is within the photography-prohibited area 210 and an image is captured by the camera 311 mounted on the terminal 300, the information processing device 100 controls the terminal 300 to delete image information generated in response to the image capture. As another example, when the self-location of the terminal 300 is within the photography-prohibited area 210, the information processing device 100 controls the terminal 300 so that the camera 311 mounted on the terminal 300 is not activated (so that the application (program) of the camera 311 is not activated).

[0016] As a specific example, the information processing device 100 acquires from the terminal 300 high-precision location information (location information obtained by combining communication systems such as GNSS (GPS) and Wi-Fi (registered trademark), a six-axis acceleration sensor (not shown), and map matching) possessed by the terminal 300, as well as location information of the photographer estimated from an image acquired by an application on the camera 311 of the terminal 300. When a photography-prohibited area 210 is registered in advance, if the information processing device 100 detects that the terminal 300 (the terminal 300's own position) is inside the photography-prohibited area 210, it prohibits the storage of images captured by the camera 311, deletes the images, and outputs a warning (security alert). By providing such a function, the information processing device 100 can allow even a commonly available terminal 300 to be brought into the photography-prohibited area 210. Such a function of the information processing device 100 may be provided as an information processing program.

[0017] [Details of Information Processing Apparatus 100] Next, the information processing apparatus 100 according to an embodiment will be described in detail. Fig. 2 is a block diagram for explaining the information processing apparatus 100 according to an embodiment.

[0018] The information processing device 100 includes, for example, a communication unit 121, a storage unit 122, a display unit 123, a speaker 124, and a control unit 110. The communication unit 121, the storage unit 122, the display unit 123, and the speaker 124 may be an embodiment of an output unit. The control unit 110 includes, for example, a first acquisition unit 111, a first determination unit 112, a second acquisition unit 113, a second determination unit 114, and an operation control unit 115. The control unit 110 may be configured, for example, by an arithmetic processing unit of the information processing device 100. The control unit 110 (for example, an arithmetic processing unit) may realize the functions of each unit (for example, the first acquisition unit 111, the first determination unit 112, the second acquisition unit 113, the second determination unit 114, and the operation control unit 115) by, for example, appropriately reading and executing various programs stored in the storage unit 122. In other words, the functions of each unit may be realized by computer implementation.

[0019] The communication unit 121 is, for example, a communication interface that can transmit and receive various information to and from a device (external device) outside the information processing device 100. The external device may be, for example, a terminal 300 or the like.

[0020] The storage unit 122 may store, for example, various information and programs. Examples of the storage unit 122 may be a memory, a solid state drive, a hard disk drive, etc. Note that the storage unit 122 may be, for example, a storage area or a server on a cloud.

[0021] The memory unit 122 stores photography-prohibited area information related to the photography-prohibited area 210. The memory unit 122 may store, as the photography-prohibited area information, information on the closed area indicated by the coordinates 211 of the photography-prohibited area 210 and the time when photography is prohibited. The photography-prohibited area 210 may be an area where photography is prohibited that is set in advance by various organizations such as a company or a government agency. The photography-prohibited area 210 may be a closed area in which coordinates 211 of multiple positions are set on the boundary (outer edge) of the area. The photography-prohibited time may be the time when photography is prohibited in the photography-prohibited area 210. The photography-prohibited time may be the start time and end time (time period) when photography is prohibited. Furthermore, information on images of the photography-prohibited area 210 may be recorded in the photography-prohibited area information. The image of the photography-prohibited area 210 may be, for example, an image of the scenery of the photography-prohibited area 210 (e.g., a still image or a video).

[0022] The display unit 123 is a display capable of displaying, for example, various characters, symbols, images, and the like.

[0023] The speaker 124 outputs, for example, voice and sound.

[0024] The first acquisition unit 111 acquires self-location information relating to the self-location of the terminal 300 from the terminal 300 equipped with the camera 311. That is, the first acquisition unit 111 acquires the self-location information from the terminal 300 via the communication unit 121. The self-location information is location information relating to the location (self-location) of the terminal 300. The self-location is the location of the terminal 300.

[0025] The first determination unit 112 determines whether the self-location is within the photography-prohibited area 210, based on the photography-prohibited area information stored in the storage unit 122 and the self-location information acquired by the first acquisition unit 111. That is, the information processing device 100 determines whether the self-location of the terminal 300 is inside or outside the photography-prohibited area 210, based on the photography-prohibited area information and the self-location information.

[0026] The terminal 300 acquires its own position using, for example, GNSS, GPS, etc. In this case, if the communication state of the terminal 300 with the satellite 400 (see FIG. 1 ) that provides the GNSS and GPS, i.e., the satellite signal reception state, is relatively poor, the accuracy of the acquired own position (position information) becomes relatively poor.

[0027] Therefore, the first determination unit 112 may estimate the location of the terminal 300 based on an SRS (Sounding Reference Signal) when communicating with the terminal 300, and may determine whether the terminal 300 is located within the photography-prohibited zone 210 based on the estimated location and its own location based on the own location information acquired by the first acquisition unit 111. That is, the first determination unit 112 may, for example, identify the base station 200 that has the strongest SRS when the terminal 300 communicates with the base station 200, and estimate that the terminal 300 is located within the communication range of the base station 200. When the first determination unit 112 identifies that the base station 200 at which the information processing device 100 (its own device) is located has the strongest SRS, it may estimate that the terminal 300 is located within the communication range of the base station 200 at which the information processing device 100 (its own device) is located. When the communication range of the base station 200 includes all or part of the photography prohibited area 210, if the terminal 300 is present within the communication range of the base station 200, the first determination unit 112 may determine that there is a possibility that the terminal 300 is within the photography prohibited area 210. In this case, the first determination unit 112 may further determine that the terminal 300 is within the photography prohibited area 210 if the self-position based on the self-position information of the terminal 300 is within the photography prohibited area 210.

[0028] Furthermore, for example, if the photography-prohibited area 210 is indoors, the terminal 300 located in the photography-prohibited area 210 cannot acquire its own position because it has difficulty communicating with the satellite 400. In this case, if the terminal 300 takes an image using the camera 311 when it is unable to acquire its own position, the terminal 300 transmits an image (image information) generated by the image capture to the information processing device 100.

[0029] That is, when the terminal 300 cannot acquire its own position, the second acquisition unit 113 acquires image information generated by capturing an image using the camera 311. That is, the second acquisition unit 113 acquires the image information from the terminal 300 via the communication unit 121. The image information records a scene (subject) around the terminal 300 captured by the camera 311 of the terminal 300. The image information may be, for example, information about a still image or a video.

[0030] The second determination unit 114 determines whether the image captured by the camera 311 was captured in the photography-prohibited zone 210 based on the image of the photography-prohibited zone 210 recorded in the photography-prohibited zone information stored in the storage unit 122 and the image information acquired by the second acquisition unit 113. That is, the second determination unit 114 uses, for example, image recognition technology such as AI to compare the image captured by the camera 311 (image based on image information) with the image of the photography-prohibited zone 210 recorded in the photography-prohibited zone information, and if it estimates that the subjects recorded in both images are the same, it determines that the image captured by the camera 311 was captured in the photography-prohibited zone 210. In other words, in this case, the second determination unit 114 determines that the image capture position is within the photography-prohibited zone 210. On the other hand, if the second determination unit 114 does not estimate that the subjects recorded in both images are the same (are not the same), it determines that the image captured by the camera 311 was captured outside the photography-prohibited zone 210. In other words, in this case, the second determination unit 114 determines that the image capturing position is outside the photography prohibited area 210 .

[0031] The operation control unit 115 controls the terminal 300 to perform a predetermined operation when the first determination unit 112 determines that the terminal's own location is within the photography-prohibited area 210. Furthermore, the operation control unit 115 may control the terminal 300 to perform a predetermined operation when the second determination unit 114 determines that the imaging position of an image is within the photography-prohibited area 210. Note that when the first determination unit 112 (or the second determination unit 114) determines that the terminal's own location is within the photography-prohibited area 210, the operation control unit 115 may control the terminal 300 to perform a predetermined operation if it is a photography-prohibited time (time zone) recorded in the photography-prohibited area information. In this case, the operation control unit 115 may control the terminal 300 to perform a predetermined operation if the time to capture the image, the time the image was captured, and the time recorded in the image match the photography-prohibited time (within the time zone) recorded in the photography-prohibited area information.

[0032] In this case, the operation control unit 115 may at least one of deleting images captured within the photography-prohibited zone 210 and prohibiting activation of the camera 311, as control of the predetermined operation of the terminal 300. That is, as an example, when the self-position of the terminal 300 is within the photography-prohibited zone 210 and an image is captured by the camera 311 mounted on the terminal 300, the information processing device 100 may control the terminal 300 via the communication unit 121 to delete image information generated in response to the image capture. As another example, when an image captured by the camera 311 of the terminal 300 is captured within the photography-prohibited zone 210, the information processing device 100 may control the terminal 300 via the communication unit 121 to delete image information generated in response to the image capture. As another example, the information processing device 100 may control the terminal 300 via the communication unit 121 so that the camera 311 mounted on the terminal 300 is not activated (so that an application (program) of the camera 311 is not activated) when the self-position of the terminal 300 is within the photography-prohibited zone 210. As another example, the information processing device 100 may control the terminal 300 via the communication unit 121 so that the camera 311 mounted on the terminal 300 is not activated (so that an application (program) of the camera 311 is not activated) when an image captured by the camera 311 of the terminal 300 is captured within the photography-prohibited zone 210.

[0033] As a control of a predetermined operation on the terminal 300, the operation control unit 115 may cause the terminal 300 to output a notification that the image will be deleted when an image captured in the photography-prohibited zone 210 and stored in the terminal 300 is to be deleted. As an example, when deleting the image described above, the operation control unit 115 may notify the terminal 300 in advance via the communication unit 121 that the image will be deleted. In this case, upon receiving the notification transmitted from the operation control unit 115, the terminal 300 may display the notification on the display unit (terminal display unit 312 (see FIG. 1)) of the terminal 300 and may output a voice or sound of the notification from the speaker (terminal speaker 313 (see FIG. 1)). This enables the terminal 300 to prompt the user of the terminal 300 to delete the image themselves.

[0034] The operation control unit 115 may perform control to grasp the imaging behavior of the terminal 300 and output a warning when at least one of the cases where the first determination unit 112 determines that the self-location is within the photography-prohibited zone 210 and the second determination unit 114 determines that the imaging position of the image is within the photography-prohibited zone 210. The operation control unit 115 may perform control to display a warning on the display unit 123 of the information processing device 100 and output a warning sound and voice from the speaker 124 of the information processing device 100. Furthermore, together with the above-mentioned warning (or after the warning), the operation control unit 115 may continuously acquire at least one of the self-location of the terminal 300 (self-location information) and the image captured by the terminal 300 (image information), and monitor (grasp) the movement of the terminal 300 and the imaging behavior of the terminal 300.

[0035] The operation control unit 115 may control the device to output a warning history. The operation control unit 115 may aggregate warning outputs to generate a history (history information) and control the output unit to output the history (warning history). That is, the operation control unit 115 may, for example, control the communication unit 121 to transmit the warning history to an external device (not shown). The external device here may be, for example, a server or a user terminal. The user terminal is a terminal used by a user of the information processing device 100 (e.g., a monitor, etc.) and may be a desktop, laptop, tablet, smartphone, etc. The operation control unit 115 may, for example, control the storage unit 122 to store the warning history. The operation control unit 115 may, for example, control the display unit 123 to display the warning history.

[0036] Note that, when photography is permitted within the photography-prohibited area 210 due to public opening or the like, the operation control unit 115 may receive in advance the area and times (start time and end time) during which photography is permitted and register this in the photography-prohibited area information. In this case, the operation control unit 115 may not implement the functions of the control unit 110 (e.g., the operation control unit 115, etc.) described above with respect to photography behavior of the terminal 300 in the area and time during which photography is permitted. That is, in this case, the operation control unit 115 may not delete images in the terminal 300 and may enable activation of the camera 311. Furthermore, the operation control unit 115 may not grasp the photography behavior of the terminal 300 and may not output a warning.

[0037] Furthermore, within the photography-prohibited area 210, information permitting photography as an exception (exception) may be posted. That is, a two-dimensional information code such as a QR code (registered trademark) or a barcode indicating that photography is permitted as an exception within the photography-prohibited area 210 may be posted within the photography-prohibited area 210. As described above, when the terminal 300 receives a notification to delete an image and displays the notification on the terminal display unit 312 in accordance with the control of the operation control unit 115, and photographs the two-dimensional information code with the camera 311, the terminal 300 may transmit information to the information processing device 100 indicating that photography is permitted as an exception within the photography-prohibited area 210. Upon receiving the information via the communication unit 121, the operation control unit 115 may determine that photography is permitted as an exception within the terminal 300, and may not delete the image in the terminal 300 and may enable the activation of the camera 311. In this case, the operation control unit 115 may not grasp the photography behavior of the terminal 300 and may not output a warning.

[0038] [Information Processing Method] Next, an information processing method according to an embodiment will be described with reference to Fig. 3, which is a flowchart illustrating the information processing method according to an embodiment.

[0039] In step ST101, the storage unit 122 stores photography-prohibited area information regarding the photography-prohibited area 210. The storage unit 122 may store, as the photography-prohibited area information, information on the closed area indicated by the coordinates 211 of the photography-prohibited area 210 and information on the time when photography is prohibited.

[0040] In step ST102, the first acquisition unit 111 acquires, from the terminal 300 equipped with the camera 311, self-location information relating to the self-location of the terminal 300.

[0041] In step ST103, the first determination unit 112 determines whether the self-location is within the photography prohibited area 210 based on the photography prohibited area information stored in step ST101 and the self-location information acquired in step ST102. The first determination unit 112 may estimate the location of the terminal 300 based on an SRS (Sounding Reference Signal) when communicating with the terminal 300. In this case, the first determination unit 112 may determine whether the self-location is within the photography prohibited area 210 based on the estimated location and the self-location based on the self-location information acquired in step ST102.

[0042] In step ST104, if the terminal 300 is unable to acquire its own position (self-position information) (in step ST102), the second acquisition unit 113 acquires image information generated by capturing an image with the camera 311 of the terminal 300.

[0043] In step ST105, the second judgment unit 114 judges whether the image captured by the camera 311 of the terminal 300 was captured in the photography-prohibited area 210 based on the image of the photography-prohibited area 210 recorded in the photography-prohibited area information stored in step ST101 and the image information acquired in step ST104.

[0044] In step ST106, if the operation control unit 115 determines in step ST103 that the own position is within the photography-prohibited zone 210, the operation control unit 115 controls the terminal 300 to perform a predetermined operation. Furthermore, if the operation control unit 115 determines in step ST105 that the image capture position is within the photography-prohibited zone 210, the operation control unit 115 may control the terminal 300 to perform a predetermined operation. In this case, as control of the predetermined operation on the terminal 300, the operation control unit 115 may delete images captured within the photography-prohibited zone 210 that are stored in the terminal 300 and prohibit activation of the camera 311. As control of the predetermined operation on the terminal 300, if the operation control unit 115 deletes images captured within the photography-prohibited zone 210 that are stored in the terminal 300, the operation control unit 115 may cause the terminal 300 to output a notification that the images will be deleted. When at least one of the cases where it is determined in step ST103 that the self-location is within the photography-prohibited area 210 and the case where it is determined in step ST105 that the photography position of the image is within the photography-prohibited area 210, the operation control unit 115 may grasp the photography behavior of the terminal 300 and perform control to output a warning. In this case, the operation control unit 115 may perform control to output a history of the warning.

[0045] [Regarding Functions and Circuits] Next, the functions and circuits of the information processing device 100 described above will be described. Each unit of the information processing device 100 may be realized as a function of a computer's arithmetic processing device or the like. That is, the first acquisition unit 111, the first determination unit 112, the second acquisition unit 113, the second determination unit 114, and the operation control unit 115 (control unit 110) of the information processing device 100 may be realized as a first acquisition function, a first determination function, a second acquisition function, a second determination function, and an operation control function (control function) by the computer's arithmetic processing device or the like. An information processing program can cause a computer to realize each of the above-mentioned functions. The information processing program may be recorded on a computer-readable non-transitory storage medium, such as a memory, a solid-state drive, a hard disk drive, or an optical disc. The storage medium may also be referred to as a non-transitory computer-readable medium that stores the information processing program. The information processing program may also be transmitted online. As described above, each unit of the information processing device 100 may be realized by a computer's arithmetic processing device or the like. The arithmetic processing device or the like may be configured, for example, by an integrated circuit or the like. For this reason, each unit of the information processing device 100 may be realized as a circuit constituting an arithmetic processing device or the like. That is, the first acquisition unit 111, the first determination unit 112, the second acquisition unit 113, the second determination unit 114, and the operation control unit 115 (control unit 110) of the information processing device 100 may be realized as a first acquisition circuit, a first determination circuit, a second acquisition circuit, a second determination circuit, and an operation control circuit (control circuit) constituting an arithmetic processing device or the like of a computer. Furthermore, the communication unit 121, the memory unit 122, the display unit 123, and the speaker 124 (output unit) of the information processing device 100 may be realized as, for example, a communication function, a memory function, a display function, and a speaker function (output function) including the functions of an arithmetic processing device or the like. Furthermore, the communication unit 121, the memory unit 122, the display unit 123, and the speaker 124 (output unit) of the information processing device 100 may be realized as, for example, a communication circuit, a memory circuit, a display circuit, and a speaker circuit (output circuit) by being configured using integrated circuits or the like.Furthermore, the communication unit 121, memory unit 122, display unit 123, and speaker 124 (output unit) of the information processing device 100 may be configured, for example, as a communication device, a memory device, a display device, and a speaker device (output device) by being composed of multiple devices.

[0046] The information processing device 100 can combine one or any combination of the above-described units. In this disclosure, the term "information" is used, but the term "information" can be replaced with "data," and the term "data" can be replaced with "information."

[0047] [Aspects and Effects of the Present Embodiment] Next, one aspect of the present embodiment and the effects of each aspect will be described. Note that each aspect described below is an example at the time of filing, and the present embodiment is not limited to the aspects described below. In other words, the present embodiment is not limited to each aspect described below, and may be realized by appropriately combining each of the above-mentioned parts. Furthermore, a lower aspect may in some cases cite any of the higher aspects. Furthermore, the effects of the present embodiment described below are only examples, and the effects of each aspect are not limited to those described below. Furthermore, each aspect may, for example, achieve at least one of the effects described below.

[0048] (Aspect 1) An information processing device of one aspect includes: a storage unit that stores photography-prohibited area information regarding photography-prohibited areas; a first acquisition unit that acquires self-location information regarding the self-location of a camera-equipped device from the device; a first determination unit that determines whether the self-location is within the photography-prohibited area based on the photography-prohibited area information stored in the storage unit and the self-location information acquired by the first acquisition unit; and an operation control unit that controls the device to perform a predetermined operation when the first determination unit determines that the self-location is within the photography-prohibited area. This allows the information processing device to take security into consideration in photography-prohibited areas (predetermined areas). That is, the information processing device can, for example, delete images taken within the photography-prohibited area. Furthermore, the information processing device can prohibit the launch of a camera application within the photography-prohibited area. In other words, the information processing device can prevent information within the photography-prohibited area and the state of the photography-prohibited area from being leaked. Furthermore, the information processing device can save companies that manufacture and sell devices the effort of developing, manufacturing, and selling devices with functions that restrict camera activation and delete images, thereby reducing the burden on those companies. Furthermore, even if a user of the terminal casually takes a photo in a photography prohibited area, the information processing device can prevent the image from being made public. In other words, the information processing device can prohibit the user from being given special treatment such as being able to take photos in a photography prohibited area.

[0049] (Aspect 2) In one aspect of the information processing device, the first determination unit may estimate the location of the terminal based on a sounding reference signal (SRS) transmitted when communicating with the terminal, and determine whether the terminal is located within a photography-prohibited area based on the estimated location and a self-location based on self-location information acquired by the first acquisition unit. This allows the information processing device to estimate the possibility that the terminal is located within a photography-prohibited area based on the SRS, even when reception conditions for a signal (satellite signal) acquired by the terminal are relatively poor. Furthermore, if the information processing device determines that the terminal is located within a photography-prohibited area based on the SRS and if the self-location of the terminal based on the signal (satellite signal) is within the photography-prohibited area, the information processing device can determine that the terminal is located within the photography-prohibited area. In other words, the information processing device can improve the accuracy of determining that the terminal is located within a photography-prohibited area, even when reception conditions for a signal (satellite signal) acquired by the terminal are relatively poor.

[0050] (Aspect 3) An information processing device of one aspect includes a second acquisition unit that acquires image information generated by capturing an image with a camera when the device cannot acquire its own location, and a second determination unit that determines whether an image captured by the camera was captured in the capturing prohibited area based on an image of the capturing prohibited area recorded in capturing prohibited area information stored in a storage unit and the image information acquired by the second acquisition unit, wherein the operation control unit may control the device to perform a predetermined operation when the second determination unit determines that the capturing position of the image is within the capturing prohibited area. In this way, the information processing device can determine whether the location of the device (capturing position) is within the capturing prohibited area based on an image captured by the camera of the device, even when the capturing prohibited area is set in a location where signal (satellite signal) reception conditions are relatively poor, such as indoors.

[0051] (Aspect 4) In the information processing device of one aspect, the operation control unit may control the predetermined operation of the terminal by deleting images captured in the photography-prohibited area and prohibiting activation of the camera, thereby enabling the information processing device to take security into consideration in the photography-prohibited area (predetermined area).

[0052] (Aspect 5) In the information processing device of one aspect, the operation control unit may control the predetermined operation of the terminal so that, when an image captured in a photography-prohibited area and stored in the terminal is to be deleted, the operation control unit causes the terminal to output a notification that the image will be deleted. This allows the information processing device to provide advance notice to the user of the terminal.

[0053] (Aspect 6) In an information processing device according to an aspect, the storage unit may store, as the photography-prohibited area information, information on a closed area indicated by coordinates of the photography-prohibited area and information on a time when photography is prohibited. This allows the information processing device to set the photography-prohibited area.

[0054] (Aspect 7) In an information processing device of one aspect, the operation control unit may be configured to control the information processing device to grasp the image capturing behavior of the device and output a warning when at least one of the first determination unit determines that the device's own location is within a photography-prohibited zone and the second determination unit determines that the image capturing position of the image is within a photography-prohibited zone. This allows the information processing device to grasp the photography behavior of the device within the photography-prohibited zone, track the subsequent movement of the device, and grasp the photography behavior of the device.

[0055] (Aspect 8) In one aspect of the information processing device, the operation control unit may be configured to control the output of a warning history. This allows the information processing device to take security into consideration in photography-prohibited areas (predetermined areas). Furthermore, by aggregating the output of warnings and compiling them as a history, the information processing device can grasp the frequency of photography in photography-prohibited areas for each user and determine whether the user poses a security threat.

[0056] (Aspect 9) In one aspect of the information processing method, a computer including a storage unit that stores photography-prohibited area information regarding photography-prohibited areas acquires, from a camera-equipped terminal, self-location information regarding the self-location of the terminal, a first determination step that determines whether the self-location is within the photography-prohibited area based on the photography-prohibited area information stored in the storage unit and the self-location information acquired by the first acquisition step, and an operation control step that controls the terminal to perform a predetermined operation when the first determination step determines that the self-location is within the photography-prohibited area. This allows the information processing method to achieve the same effects as the information processing device of the above-mentioned aspect.

[0057] (Aspect 10) An information processing program of one aspect causes a computer having a storage unit that stores photography-prohibited area information regarding photography-prohibited areas to implement the following: a first acquisition function that acquires self-location information regarding the self-location of a camera-equipped terminal from the terminal, a first determination function that determines whether the self-location is within the photography-prohibited area based on the photography-prohibited area information stored in the storage unit and the self-location information acquired by the first acquisition function, and an operation control function that controls the terminal to perform a predetermined operation when the first determination function determines that the self-location is within the photography-prohibited area. As a result, the information processing program can achieve the same effect as the information processing device of the above-mentioned aspect.
