Description

  The present invention relates to an information terminal having a security function, an information terminal control method, a control program, and a recording medium.

  In recent years, with the spread of information terminals having a security function, models that acquire position information of an information terminal using a GPS device and perform security management according to the acquired position information have been developed one after another.

  For example, Patent Document 1 discloses an information processing apparatus that performs security management using position information. Specifically, the information processing apparatus acquires position information of the information processing apparatus, and data for determining which functions are restricted among the functions of the information processing apparatus according to the position information. Based on the security policy data, the information processing apparatus restricts functions that require security management according to the position information.

  Patent Document 2 discloses a storage device having a security function. Specifically, the storage device detects the position of the storage device, the location where the storage device is located is preset, the preset location is compared with the measured location, and the measurement is performed. If the location is different from the preset location, access to the storage medium of the storage device is prohibited.

  Patent Document 3 discloses a portable terminal information management system for simultaneously satisfying the contradiction between convenience and safety of information. Specifically, the portable terminal information management system transfers display information stored in the memory card to the first storage unit or the second storage unit based on the current position of the user. That is, when it is determined that the user position information and the previous user position information do not match, the display information stored in the storage unit of the memory card, the first storage unit, or the second storage unit is changed to the other two. A storage position indicating which of the two storage units is to be stored is determined based on the changed user position information.

JP 2009-070073 (April 2, 2009) JP 2009-259115 A (released on November 5, 2009) JP 2010-086165 A (published on April 15, 2010)

  However, when performing security management according to location information, when location information and security functions are registered in advance in association with each other, the following problems occur because the location information is conventionally represented by longitude and latitude. It was. That is, it is difficult for the user of the information terminal to grasp the location indicated by the position information, and it is troublesome to register the position information in association with the security function. Furthermore, when the user confirms or changes the association information between the registered position information and the security function, it is difficult to know what setting (location information) is set.

  For example, the technique described in Patent Document 1 limits functions according to position information based on security policy data. However, in order to register the security policy data, it is necessary to grasp the position information. How to grasp the position information is not specifically described in the cited document 1. Moreover, it is difficult to confirm the range where the function is restricted, and it is also troublesome to change the range.

  The technique described in Patent Document 2 prohibits access to a storage medium when the measurement position is different from the set location. However, as in Patent Document 1, the user does not know how to register the setting location and how to confirm / change the setting location, and it is not easy for the user.

  The technique described in Patent Document 3 compares the user position information with the previous user position information and determines the storage position. However, the positional information and the security function are not registered in association with each other. Therefore, the user cannot manage the security function according to a predetermined location.

  The present invention has been made in view of the above-described problems, and its purpose is to easily associate and register position information and security functions, and information that can be easily confirmed / changed later. It is to realize a control method of a terminal and an information terminal, a control program, and a recording medium.

  In order to solve the above-described problem, an information terminal according to the present invention is an information terminal that restricts the function of the own information terminal according to the current position of the own information terminal, and includes a display unit that displays an image, and position information. And a storage unit for storing image data with position information to which is added, function restriction setting information indicating the content of the function of the own information terminal while displaying the image of the image data with position information on the display unit And a function restriction setting means for storing the function restriction setting information in the storage unit in association with the image data with position information.

  An information terminal control method according to the present invention is an information terminal control method that restricts functions of the own information terminal according to the current position of the own information terminal, wherein the information terminal displays an image. And a storage unit for storing the image data with position information to which the position information is added. The image of the image data with position information is displayed on the display unit, and the function restricts the function of the information terminal. It includes a function restriction setting step of specifying function restriction setting information to be shown and storing the function restriction setting information in the storage unit in association with the image data with position information.

  According to the above configuration, in the information terminal that restricts the function of the own information terminal according to the current position of the own information terminal, the position information is added with the function restriction setting information indicating the content that restricts the function of the own information terminal. The image data with position information is stored in the storage unit in association with the image data. Therefore, when the information terminal restricts the function of the own information terminal according to the current position of the own information terminal, the information terminal refers to the position information added to the image data with the position information, and the position information near the current position. The function of the self-information terminal can be restricted using the function restriction setting information associated with the image data with position information to which is added.

  In particular, in the information terminal, it is not the position information but the image data that is directly associated with the function restriction setting information. Therefore, when registering or changing the function restriction by associating the position information with the function restriction setting information, the user can perform the operation while viewing the image. Therefore, since the position indicated by the position information can be specifically recognized as an image, setting work is easy. Of course, in the image data with position information, it is desirable that position information such as the longitude and latitude of the position is added to the image data obtained by photographing the target at the position where the function restriction registration is desired.

  Furthermore, the information terminal according to the present invention includes a plurality of applications, and the function restriction setting information associated with one piece of image data with position information includes contents of function restrictions for the plurality of applications. It is characterized by being.

  According to the above configuration, further, by extracting one piece of image data with position information, it is possible to restrict functions for a plurality of applications, so that registration and change of function restrictions are easy.

  Furthermore, in the information terminal according to the present invention, the storage unit includes a folder for each function restriction setting information, and the function restriction setting unit displays the image data with position information and the folder on the display unit. At the same time, it is characterized in that function restriction setting information to which the folder is assigned is associated with the image data with position information moved to the folder by the user.

  According to the above configuration, since a folder is prepared for each function restriction setting information, all image data with position information under one folder is associated with the function restriction setting information to which the folder is assigned. It will be.

  Therefore, data such as a management table for managing image data with position information and function restriction setting information in association with each other is not necessary, and memory can be saved. In addition, since the user operation for registering or changing the function restriction is also a movement of the image data between the folders, the user can operate intuitively and is easy.

  Furthermore, an information terminal according to the present invention includes an imaging unit that captures an image to generate image data, a position acquisition unit that acquires a current position of the own information terminal when the imaging unit captures an image, and the imaging unit that generates the information terminal. Image data generation means with position information for generating the image data with position information by adding the position information acquired by the position acquisition means to the image data.

  According to the above configuration, image data with position information can be easily generated by adding position information such as the latitude and longitude of the position to the image data obtained by photographing the target at the position where the function restriction is to be registered. can do. Therefore, it becomes easy to register or change the function restriction by associating the position information with the function restriction setting information.

  The information terminal may be realized by a computer. In this case, the information terminal control program for causing the information terminal to be realized by the computer by causing the computer to operate as the respective means, and the program recorded therein. Computer-readable recording media are also within the scope of the present invention.

  As described above, an information terminal according to the present invention includes a display unit that displays an image, and a storage unit that stores image data with position information to which position information is added, and stores the image of the image data with position information. A function restriction that is displayed on the display unit, specifies function restriction setting information indicating the content of restricting the function of the own information terminal, and stores the function restriction setting information in the storage unit in association with the image data with position information. The configuration further includes setting means.

  In the information terminal control method according to the present invention, the information terminal includes a display unit that displays an image, and a storage unit that stores image data with position information to which the position information is added. An image of image data is displayed on the display unit, function restriction setting information indicating contents for restricting the function of the own information terminal is specified, and the function restriction setting information is associated with the image data with position information and the storage unit The function restriction setting step is stored in the method.

  According to the above configuration, it is not the position information but the image data that is directly associated with the function restriction setting information. Therefore, when registering or changing the function restriction by associating the position information with the function restriction setting information, the user can perform the operation while viewing the image. Therefore, since the position indicated by the position information can be specifically recognized as an image, there is an effect that the setting operation is easy.

  An information terminal according to an embodiment of the present invention will be described below with reference to the drawings. Note that the information terminal according to the present embodiment is realized as a mobile phone. For this reason, hereinafter, the information terminal according to the present embodiment is simply referred to as a mobile phone.

  However, the present invention can be applied not only to mobile phones but also to information terminals generally provided with a security function.

[First Embodiment]
One embodiment of the present invention will be described below with reference to FIGS.

(Outline of processing)
An outline of the processing of this embodiment will be described with reference to FIG. FIG. 2 is a diagram illustrating an example of the processing outline of the present embodiment, and is a diagram illustrating an example in which security management is performed by dividing a position into a workplace and a place other than the workplace. (A) of FIG. 2 is a figure which shows the scene which preserve | saves the image image | photographed with the camera with a positional information. (B) of FIG. 2 is a figure which shows the scene which switches a security level based on position information.

  As shown in FIG. 2A, first, the user photographs his / her workplace with a camera. After shooting, in the mobile phone 1 (information terminal; see FIG. 1), position information indicating the shooting location (that is, position information in the vicinity of the workplace) is added to the shot image and stored.

  Then, configure security settings. Here, the security setting is a setting of a security level and an effective range.

  A specific setting method will be described later. Here, for example, the security level is set to “low”, and the effective range is set to “20 m” (that is, 20 meters). In the above case, the mobile phone 1 sets the security level to “low” within a radius of 20 m centering on the position information added to the image, and sets the security level to “high” outside the above range. Means managing security.

  Then, as shown in FIG. 2B, when the user having the mobile phone 1 is at his / her workplace (that is, within a radius of 20 m centering on the position information added to the photographed image). Mobile phone 1 automatically sets the security level to “low”. On the other hand, when the user is outside his / her workplace (that is, outside the above range), the mobile phone 1 automatically sets the security level to “high”.

  Next, the security level and effective range will be described with reference to FIG.

  FIG. 3 is a diagram illustrating an example of a management table that stores setting information related to the security function in the present embodiment. FIG. 3A is a management table showing a security state corresponding to each image. FIG. 3B is a management table showing the effective state of the security function corresponding to each security level.

  As shown in FIG. 3A, for example, the line corresponding to the number “1” is centered on the position information added to the image file “IMG0001.jpg” in the effective range within the radius “20 m”. This indicates that the security level is set to “high”.

  As shown in (b) of FIG. 3, the security level “high” is, for example, a security level for the “standby screen”, “mail”, “phone”, “phone book”, and “image list” functions. It is defined to set the function to ON. That is, when the security level is set to “high”, the above five functions cannot be used by the user.

  Further, for example, the line corresponding to the number “3” shown in FIG. 3A is centered on the position information added to the image file “dcf0023.jpg”, and within the effective range within the radius “100 m”. This indicates that the security level is set to “low”.

  As shown in FIG. 3B, the security level “low” is set to OFF for the functions other than the “phone book”, for example, and for the “phone book” function, It is defined to set the security function to ON. That is, when the security level is set to “low”, only the “phone book” function is restricted so that it cannot be used, and functions other than the “phone book” (“standby screen”, “mail”, “phone” and “image” “List”) is ready for use.

  In the present embodiment, it is assumed that position information is added to all the image files described in the “file name” column in the management table shown in FIG. In this embodiment, as a method for adding position information, position information such as a geotag is added to Exif data of an image file. The method for adding the position information is not particularly limited as long as the image file and the position information can be managed in association with each other, and the position information may be held as integral data with the image file as in the present embodiment. Alternatively, it may be held as separate data. That is, for example, the position information may be data separate from the image file, and the image file and the position information may be associated with each other and managed by the management table.

  In the present embodiment, the effective state of the security function of the management table shown in FIG. 3B may be determined in advance or can be changed by a user operation. It may be.

  In the present embodiment, the security level is always “high” outside the effective range. The security level outside the effective range may be changeable by a user operation.

  Furthermore, the processing outline of the present embodiment is not limited to the processing outline shown in FIG.

  For example, with regard to (a) in FIG. 2, the image used for the image with position information is not limited to the image captured by the camera of the own device, and an image transferred from an external device may be used. Further, the position information may not be added to the image from the beginning, but may be added later by using software (for example, Kashmir, AbleCV, etc.) for adding the position information.

  Further, regarding FIG. 2B, when managing security functions, as described above, according to the management table shown in FIG. 3B, security functions corresponding to a plurality of functions are turned on for each security level. / OFF may be switched all at once, or the security function may be switched on / off for each function (for example, “mail”, “phone”, etc.) depending on whether the mobile phone is within the effective range. .

(Main components of mobile phone)
The configuration of the mobile phone 1 according to the present embodiment will be described with reference to FIG. FIG. 1 is a block diagram showing a main configuration of the mobile phone 1.

  As shown in FIG. 1, the mobile phone 1 includes a GPS 10, a storage unit 20, an input unit 30, a display unit 40, and a control unit 50. The mobile phone 1 may include members such as a speaker, a microphone, and a battery in addition to these members, but these members are not shown because they are not related to the features of the invention.

  The GPS 10 receives radio waves transmitted from an artificial satellite and measures the longitude and latitude and altitude of the current position. Note that the present location is not limited to GPS, and any device that can identify the current location may be used. For example, the current location may be received from the base station through communication with the base station.

  The storage unit 20 executes a control program and an OS program executed by the control unit 50, and when the control unit 50 executes various functions of the mobile phone 1 (for example, security setting and security function switching described later). Various data to be read are stored. In the present embodiment, the storage unit 20 stores, for example, data such as image data, a management table ((a) and (b) in FIG. 3), and current security setting information. The storage unit 20 is realized by, for example, an EPROM, an EEPROM, a flash memory, or the like, which is a nonvolatile memory capable of rewriting contents. Note that the storage unit that stores information that does not require rewriting of contents may be realized by a ROM that is a read-only semiconductor memory, not shown, different from the storage unit 20.

  The input unit 30 acquires a user operation instruction and generates an instruction signal.

  The display unit 40 displays an image in accordance with an instruction from the control unit 50. The display unit 40 only needs to display an image in accordance with an instruction from the control unit 50. For example, an LCD (liquid crystal display), an organic EL display, a plasma display, or the like can be applied.

  The control unit 50 performs various calculations by executing a program read from the storage unit 20 to a temporary storage unit (not shown), and comprehensively controls each unit included in the mobile phone 1. .

  For convenience of explanation, in the control unit 50, a block B1 surrounded by a broken line is a functional block for switching the security function, and a block B2 surrounded by a broken line is a functional block for performing security setting. .

  In the present embodiment, the control unit 50 includes, as the block B1, a position information acquisition unit 501 (position information acquisition unit), an image file extraction unit 502, an image file selection unit 503, a setting information specifying unit 504, and a current setting. An information acquisition unit 505 and a security function control unit 506 are provided. Further, the block B2 includes a display control unit 507, an operation acquisition unit 508, an image file analysis unit 509, and a security setting unit 510 (function restriction setting unit). Each unit (501 to 510) of the control unit 50 can be realized by the CPU reading and executing a program stored in a storage device realized by a ROM or the like to a temporary storage unit realized by a RAM or the like. .

  Below, first, each part with which block B1 is provided is demonstrated.

  The position information acquisition unit 501 reads out longitude and latitude position information acquired from the GPS 10.

  The image file extraction unit 502 includes a position information acquisition unit 502 within an effective range (see (a) of FIG. 3) associated with the image from images with position information stored in the storage unit 20. Extracts information including the position information read out.

  When there are a plurality of images extracted by the image file extraction unit 502, the image file selection unit 503 selects one image according to a priority determination method described later.

  The setting information specifying unit 504 specifies the security level based on the extracted (or sorted) image with reference to the management table shown in FIG. 3A, and based on the specified security level. Referring to the management table shown in FIG. 3B, the security setting information (function restriction setting information) of each function is specified.

  The current setting information acquisition unit 505 acquires the current security setting information from the storage unit 20.

  The security function control unit 506 compares the security setting information specified by the setting information specifying unit 504 with the current security setting information acquired by the current setting information acquisition unit 505. The security state is changed based on the security setting information specified by the unit 504.

  Next, each part with which block B2 is provided is demonstrated.

  The display control unit 507 generates an image to be displayed on the display unit 40 and outputs the generated image to the display unit 40.

  The operation acquisition unit 508 acquires the instruction signal generated by the input unit 30.

  The image file analysis unit 509 analyzes whether or not position information is added to the image file, and extracts the position information when it is added. Further, it is analyzed whether or not information such as a security level and an effective range is associated with the image file, and when it is associated, the information is extracted.

  The security setting unit 510 associates the security setting information input by the user acquired by the operation acquisition unit 508 with the image selected by the user, and saves it in the management table shown in FIG.

(Security setting process flow)
The flow of security setting processing in the mobile phone 1 will be described with reference to FIGS. FIG. 4 is a flowchart showing an example of security setting processing in the mobile phone 1. FIG. 5 is a screen transition diagram illustrating an example of security setting processing in the mobile phone 1.

  As shown in FIG. 4, first, the display control unit 507 controls to create a list of images on the mobile phone 1 and display the list on the display unit 40 (S101). FIG. 5A is a diagram illustrating an example of an image list screen displayed on the display unit 40. Here, an image without position information may also be included.

  Next, when image data is selected by a long press or the like, the operation acquisition unit 508 detects an input of “image data selection” (S102). Then, the image file analysis unit 509 is notified of information for identifying the selected image (in this embodiment, “file name”).

  Next, the image file analysis unit 509 reads the image file from the storage unit 20 based on the “file name” notified by the operation acquisition unit 508, and determines whether or not position information is added to the image file. Analyze (S103). When the image file analysis unit 509 determines that position information has been added (Yes in S103), the display control unit 507 displays “security” on the display unit 40 together with buttons such as “edit” and “wallpaper registration”. The image operation menu on which the “” button is displayed is displayed. FIG. 5B shows an example of an image operation menu with a “security” button.

  On the other hand, when the image file analysis unit 509 determines that position information is not added (No in S103), the display control unit 507 displays a normal image operation menu on the display unit 40 (S104).

  The normal image operation menu is a menu displayed after long-pressing one image from the image list screen in a normal case (position information is not added to the image data). Specifically, in the normal image operation menu, buttons such as “Edit” and “Register Wallpaper” are displayed, but the “Security” button is not displayed or is displayed in gray, etc. It is impossible. Since the normal image operation menu and the processing after the normal image operation menu are displayed are not related to the feature points of the present invention, the illustration of the menu and the subsequent processing are omitted.

  Next, when the “security” button is selected in the image operation menu with the “security” button, the operation acquisition unit 508 detects “select security” (S106). Then, this is notified to the image file analysis unit 509.

  When the image file analysis unit 509 receives the notification from the operation acquisition unit 508, the image file analysis unit 509 refers to the management table shown in FIG. 3A based on the “file name” of the selected image. The security level and effective range associated with the “file name” are displayed (S107). For example, if the image does not exist in the management table shown in FIG. 3A, the security level is “none” and the effective range is “none” as default values (S107). FIG. 5C is a diagram illustrating an example of a display when the current security setting of an image is a default value.

  Next, the operation acquisition unit 508 acquires the “security level” (for example, high, medium, low, etc.) input by the user from the input unit 30 (S108). FIG. 5D illustrates an example of a “security level” setting screen.

  Subsequently, the operation acquisition unit 508 acquires an “effective range” (security range) (for example, a radius of 20 m, 100 m, 1000 m, etc.) input by the user from the input unit 30 (S109). FIG. 5E is a diagram illustrating an example of a selection screen for “effective range” (security range).

  Subsequently, the operation acquisition unit 508 receives the instruction signal generated by the input unit 30 (S110). When the operation acquisition unit 508 receives a “cancel” signal from the input unit 30 (No in S110), the screen returns to the current security status display screen of the image (S107; see FIG. 5C).

  On the other hand, when the operation acquisition unit 508 receives an “OK” signal from the input unit 30 (Yes in S110; see FIG. 5F), the “security level”, “effective range”, and The file name of the selected image is transmitted to the security setting unit 510.

  Then, based on the information received from the operation acquisition unit 508, the security setting unit 510 sets security setting information in which “security level” and “effective range” are associated with the “file name” of the image in ( It is stored in the management table shown in a) (S111). FIG. 5G is a diagram illustrating an example of a screen displayed when information received from the operation acquisition unit 508 is stored in the management table illustrated in FIG.

(Flow of security function switching process)
A flow of security function switching processing in the mobile phone 1 will be described with reference to FIG. FIG. 6 is a flowchart showing an example of the security function switching process in the mobile phone 1.

  As shown in FIG. 6, first, the position information acquisition unit 501 acquires the current position from the GPS 10 (S201).

  Subsequently, the image file extraction unit 502 uses the position information acquisition unit 501 to add an effective range (see (a) of FIG. 3) associated with the image from the images stored in the storage unit 20. The image including the acquired current position is searched and extracted (S202).

  Next, the image file extraction unit 502 determines whether there is the extracted image (S203).

  On the other hand, when it is determined that there is the extracted image (Yes in S203), the image file extraction unit 502 determines whether there are a plurality of the determination target images (S205).

  When the image file extraction unit 502 determines that there are a plurality of extracted images (Yes in S205), the image file selection unit 503 selects the image with the highest priority.

  Here, the priority order determination method in the present embodiment will be described with reference to FIG. FIG. 7 is a diagram illustrating a basic pattern when there are a plurality of images including the current position. A circle area in FIG. 7 indicates an effective range associated with the image, and a shadow area indicates a portion where the effective range overlaps. FIG. 7A is a diagram illustrating an example of the case where all overlap within the effective range associated with the extracted image (completely included in one effective range). FIG. 7B is a diagram illustrating an example in which the effective ranges associated with the extracted images partially overlap.

  As a method for determining the priority order in the present embodiment, first, as shown in FIG. 7A, when all overlap within the effective range associated with the extracted image, the innermost effective range is determined. The security setting information associated with the held image is valid. Furthermore, when there are a plurality of effective ranges on the innermost side and the effective ranges partially overlap as shown in FIG. 7B, the security level is one of the plurality of effective ranges. The security setting information associated with the image having the highest effective range is made valid.

  The priority determination method is not particularly limited as long as it is possible to identify security setting information by selecting one image. For example, the highest security level or the lowest security level is always selected. May be.

  The image file selection unit 503 first selects an image having the innermost effective range in the pattern shown in FIG. 7A based on the priority order determination method (S206). Subsequently, the image file selection unit 503 selects an image having an effective range with the highest security level in the pattern shown in FIG. 7B (S207). Thus, one image is selected.

  Specifically, for example, in the pattern shown in FIG. 7A, an image having the innermost effective range is selected. As a result, one image or a plurality of images that overlap a part of the effective range are selected. When one image is selected, the process of S207 may be omitted. However, when a plurality of images are selected, the security pattern in the pattern shown in FIG. Select the image with the highest effective range. As a result, one image is selected.

  Then, the setting information specifying unit 504 specifies the security level to be set based on the management table shown in FIG. 3A (S208).

  On the other hand, when the image file extraction unit 502 determines that the extracted images are not plural (one image) (No in S205), the setting information specifying unit 504 displays the management table shown in FIG. The security level to be set is specified based on (S208).

  If the image file extraction unit 502 determines that there is no extracted image (No in S203), the setting information specifying unit 504 determines that the setting information specifying unit 504 is out of the effective range (the image including the current position does not exist, that is, the current position Is not included in any of the effective ranges associated with the image), and the security level to be set is specified (S204). In this embodiment, since the security level outside the effective range is always “high”, the security level to be set is specified as “high”.

  After the setting information specifying unit 504 specifies the security level to be set, the setting information specifying unit 504 notifies the security function control unit 506 of the specified security level.

  Next, the current setting information acquisition unit 505 acquires the current security setting information from the storage unit 20 and notifies the security function control unit 506 of the current security setting information.

  Then, the security function control unit 506 compares the security level to be set notified by the setting information specifying unit 504 with the current security setting information notified by the current setting information acquisition unit 505 (S209).

  If the result of the comparison is “different” (Yes in S209), the security function control unit 506 changes the security state to the security level to be set (S210). Then, the newly set security level is stored in the storage unit 20 as current setting information. Thereafter, the control unit 50 determines whether or not to end the security function switching process (S211).

  On the other hand, if the comparison result is “same” (No in S209), the control unit 50 determines whether or not to end the security function switching process (S211).

  When the control unit 50 determines to end the security function switching process (Yes in S211), the control unit 50 ends the security function switching process (S212). On the other hand, when the control unit 50 determines not to end the security function switching process (No in S211), the position information acquisition unit 501 repeatedly acquires the current position from the GPS (S201).

[Second Embodiment]
In the first embodiment, the example in which the security setting is performed from the image list screen in the mobile phone 1 has been described. However, as the second embodiment, when the mobile phone 2 (information terminal) captures an image with the camera, At the same time, an example of performing security setting will be described in detail with reference to FIGS.

  In addition, about the same component as 1st Embodiment, the same member number is attached | subjected and the description is abbreviate | omitted. Here, differences from the first embodiment will be mainly described, and components that are not particularly described have the same configurations and functions as those of the first embodiment.

(Main components of mobile phone)
A configuration of the mobile phone 2 according to the present embodiment will be described with reference to FIG. FIG. 8 is a block diagram showing a main configuration of the mobile phone 2.

  As shown in FIG. 8, the mobile phone 2 further includes a camera 60, a camera control unit 511 (imaging unit) as a block B2 of the control unit 50, and an image finishing unit 512 (image data generation unit). Other than that, the configuration is the same as that of the mobile phone 1 shown in FIG.

  The camera 60 is for taking a photograph or the like.

  The camera control unit 511 activates the camera 60 or causes it to take a picture.

  The image finishing unit 512 finishes an image photographed by the camera 60 with or without position information and stores it in the storage unit 20. Here, it is assumed that the position information is acquired by the GPS 10 at the time of shooting with the camera 60, immediately before shooting or immediately after shooting, under the control of the position information acquisition unit 501.

(Security setting process flow)
A flow of security setting processing in the mobile phone 2 will be described with reference to FIGS. 9 and 10. FIG. 9 is a flowchart illustrating an example of security setting processing in the mobile phone 2. FIG. 10 is a screen transition diagram illustrating an example of security setting processing in the mobile phone 2.

  As shown in FIG. 9, first, the camera control unit 511 activates the camera photographing process and displays a screen capable of photographing (S301). (A) of FIG. 10 is a figure which shows an example of the screen after starting a camera imaging | photography process.

  Then, the camera control unit 511 determines whether or not to end the camera shooting process due to the pressing of the clear key or the like, or due to timeout (S302). If the camera control unit 511 determines to end the camera shooting process (Yes in S302), it ends the camera shooting process (S303).

  On the other hand, when the camera control unit 511 determines not to end the camera shooting process (No in S302), the operation acquisition unit 508 receives the user's shooting instruction signal (when it detects that the user has pressed the shutter). The camera control unit 511 is notified. Upon receiving the notification from the operation acquisition unit 508, the camera control unit 511 causes the camera 60 to perform camera shooting (S304).

  Subsequently, the image finishing unit 512 determines whether or not to save an image captured by the camera as an image with position information (S305). FIG. 10B is a diagram illustrating an example of a screen after an image is captured by the camera.

  If it is determined that the image finishing unit 512 does not store the image with position information (No in S305), the image finishing unit 512 stores the captured image as a normal image (image without position information) in the storage unit 20 (S306). Thereafter, the display control unit 507 causes the display unit 40 to display a screen (see (h) in FIG. 10) that can be taken after the camera is activated (S301).

  On the other hand, if the image finishing unit 512 determines that the image is to be stored as an image with position information (Yes in S305), the image finishing unit 512 acquires the current position from the position information acquisition unit 501, adds it to the captured image, and stores it in the storage unit 20. Save (S307).

  Next, the display control unit 507 displays default security setting information on the display unit 40 (S308). The default security setting information is information in which the security level is “none” and the effective range is “none”. In other words, the security level is not set. FIG. 10C shows a screen on which default security setting information is displayed.

  Next, the operation acquisition unit 508 detects and determines whether or not the user has selected the “setting” button (see FIG. 10C) (S309).

  When the operation acquisition unit 508 detects that the user has selected the “cancel” button (see FIG. 10C) (that is, the “set” button has not been selected) (No in S309), display control is performed. The unit 507 causes the display unit 40 to display a screen (see (h) of FIG. 10) that can be taken after the camera is activated (S301).

  On the other hand, when the operation acquisition unit 508 detects that the user has selected the “Setting” button (Yes in S309), the “security level” (for example, high, medium, Low) is acquired (S310). FIG. 10D is a diagram illustrating an example of a “security level” setting screen.

  Subsequently, the operation acquisition unit 508 acquires the “effective range” (security range) (for example, a radius of 20 m, 100 m, 1000 m, etc.) input by the user from the input unit 30 (S311). FIG. 10E is a diagram showing an example of a selection screen for “effective range” (security range).

  Subsequently, the operation acquisition unit 508 determines a user input signal from the input unit 30 (S312). When the operation acquisition unit 508 receives a “cancel” signal from the input unit 30 (No in S312), the operation acquisition unit 508 returns to the default security setting information display screen (S308; see FIG. 10C).

  On the other hand, when the operation acquisition unit 508 receives the “OK” signal from the input unit 30 (Yes in S312; see FIG. 10F), the “security level”, “effective range”, and The file name of the selected image is transmitted to the security setting unit 510.

  Then, the security setting unit 510 stores the security setting information in the management table shown in FIG. 3A based on the information received from the operation acquisition unit 508 (S313). FIG. 10G is a diagram illustrating an example of a screen displayed when information received from the operation acquisition unit 508 is stored in the management table illustrated in FIG.

  Thereafter, the display control unit 507 causes the display unit 40 to display a screen (see (h) in FIG. 10) that can be taken after the camera is activated (S301).

[Third Embodiment]
In the first and second embodiments, the example in which the security level and the effective range are selected by the user and the security setting is performed in the mobile phones 1 and 2 has been described. In the telephone 3 (information terminal), an example is shown in which a setting folder comprising a combination of a security level and an effective range is prepared in advance, and security setting is performed by dropping an image file into the setting folder. This will be described in detail based on the above.

  In addition, about the same component as 1st Embodiment, the same member number is attached | subjected and the description is abbreviate | omitted. Here, differences from the first embodiment will be mainly described, and components that are not particularly described have the same configurations and functions as those of the first embodiment.

(Main components of mobile phone)
The configuration of the mobile phone 3 is the same as the configuration of the mobile phone 1 shown in FIG. 1 except that there is no management table shown in FIG. The description is omitted. That is, in the present embodiment, the setting folder is used instead of the management table shown in FIG.

(Security setting process flow)
A security setting process flow in the mobile phone 3 will be described with reference to FIGS. 11 and 12. FIG. 11 is a flowchart illustrating an example of security setting processing in the mobile phone 3. FIG. 12 is a screen transition diagram illustrating an example of security setting processing in the mobile phone 3.

  As shown in FIG. 11, first, the display control unit 507 creates a list of setting folders and a list of image files in the mobile phone 3 and controls them to be displayed on the display unit 40 as a security setting screen. (S401). (A) of FIG. 12 is a figure which shows an example of the security setting screen currently displayed on the display part 40. As shown in FIG.

  The setting folder will be described with reference to FIG. FIG. 13 is a tree structure diagram showing the relationship between the setting folder and the image file. In the present embodiment, the setting folder exists under the image folder together with the image file. Among the image files, the security setting is performed by moving an image file with position information to the setting folder.

  Here, the security state of the image file existing under each setting folder is not determined by the image file alone, but is determined by which folder it is under. For example, an image file under the “high / 20 m” folder is an image whose security level is set to “high” within an effective range within a radius “20 m” centering on the position information added to the image file. It is a file.

  Further, the image file without position information may be controlled not to be dropped on the operation screen, or may be controlled not to be displayed on the security setting screen. Alternatively, the image file with position information and the normal image file without position information may be displayed so as to be distinguished.

  Next, the operation acquisition unit 508 determines whether or not to end the security setting by detecting that the clear key or the like is pressed (S402). When the operation acquisition unit 508 determines to end the security setting (Yes in S402), the control unit 50 ends the display of the security setting screen.

  On the other hand, when the operation acquisition unit 508 determines not to end the security setting (No in S402), the operation acquisition unit 508 determines whether or not the image file with position information has been dropped into the setting folder (S403).

  When the operation acquisition unit 508 determines that the image file with position information has not been dropped into the setting folder (No in S403), the display control unit 507 controls the display unit 40 to continue displaying the security setting screen. (S401).

  On the other hand, when the operation acquisition unit 508 determines that the image file with position information has been dropped into the setting folder (see (b) in FIG. 10) (Yes in S403), the security setting unit 510 converts the image file into the above-described image file. Move to the setting folder (see (c) of FIG. 10) and perform security setting (S404).

  Thereafter, the display control unit 507 controls the display unit 40 to continue displaying the security setting screen (see FIG. 10D) (S401).

(Flow of security function switching process)
The flow of security function switching processing in the mobile phone 3 will be described with reference to FIG. FIG. 14 is a flowchart illustrating an example of security function switching processing in the mobile phone 3.

  As shown in FIG. 14, first, the position information acquisition unit 501 acquires the current position from the GPS 10 (S601).

  Subsequently, the image extraction unit 502 searches for and extracts an image including the current position acquired by the position information acquisition unit 501 in the effective range of the setting folder from images under each setting folder. (S602).

  Next, the image file extraction unit 502 determines whether there is the extracted image (S603).

  When the image file extraction unit 502 determines that there is no extracted image (No in S603), the setting information specifying unit 504 refers to the security setting information outside the effective range and specifies the security level to be set. (S604). In the present embodiment, the security level outside the effective range is always specified as “high”.

  On the other hand, when it is determined that there is the extracted image (Yes in S603), the image file extraction unit 502 determines whether there are a plurality of the determination target images (S605).

  When the image file extraction unit 502 determines that there are a plurality of extracted images (not one) (Yes in S605), the image file selection unit 503 uses the priority described in FIG. 7 in the first embodiment. Based on the order determination method, one image with the highest priority is selected. Specifically, first, in the pattern shown in FIG. 7A, an image having the innermost effective range is selected (S606). Subsequently, the image file selection unit 503 selects an image having an effective range with the highest security level in the pattern shown in FIG. 7B (S607). As a result, one image is selected.

  The setting information specifying unit 504 specifies the security level to be set based on the folder name of the setting folder including the selected one image (S608).

  On the other hand, when the image extraction unit 502 determines that there are not a plurality of extracted images (one image) (No in S605), the setting information specifying unit 504 sets the setting folder including the extracted one image. The security level to be set is specified based on the folder name (S608).

  After the setting information specifying unit 504 specifies the security level to be set, the setting information specifying unit 504 notifies the security function control unit 506 of the specified security level.

  Next, the current setting information acquisition unit 505 acquires the current security setting information from the storage unit 20 and notifies the security function control unit 506 of the current security setting information.

  The security function control unit 506 compares the security level to be set notified by the setting information specifying unit 504 with the current security setting information notified by the current setting information acquisition unit 505 (S609).

  If the comparison result is “different” (Yes in S609), the security function control unit 506 changes the security state to the security level to be set (S610). Then, the newly set security level is stored in the storage unit 20 as current setting information. Then, the control unit 50 determines whether or not to end the security function switching process (S611).

  On the other hand, when the result of the comparison is “same” (No in S609), the security function control unit 506 determines whether or not to end the security function switching process (S611).

  When the control unit 50 determines to end the security function switching process (Yes in S611), the control unit 50 ends the security function switching process (S612). On the other hand, when the control unit 50 determines not to end the security function switching process (No in S611), the position information acquisition unit 501 repeatedly acquires the current position from the GPS 10 (S601).

  In the above description, the image file is actually moved to the setting folder as the file is moved on the screen. However, the security assigned to the setting folder on the screen is not actually moved. For the setting, only the security setting information (security level, effective range) of the management table may be rewritten. In this case, it is not necessary to actually move the image file, and the processing speed can be improved.

[Fourth Embodiment]

FIG. 15 is a flowchart illustrating an example of security setting processing in the mobile phone 4. FIG. 16 is a screen transition diagram illustrating an example of security setting processing in the mobile phone 4.

  As shown in FIG. 15, first, the display control unit 507 creates a list of icons and a list of images on the mobile phone 4 and controls them to be displayed on the display unit 40 as a security setting screen ( S701). FIG. 16A is a diagram illustrating an example of a security setting screen displayed on the display unit 40. For example, for an icon displayed as “high / 100”, the security level is set to “high” in an effective range within a radius “20 m” centering on the position information added to the image file where the icon is dropped. Icon to set. As described above, the display screen displays a list of icons to which each security setting is assigned together with the image file.

  Note that an image file without position information may be displayed in gray so that an icon cannot be dropped on the image file, or may be controlled not to be displayed on the security setting screen. Alternatively, the image file with position information and the normal image file without position information may be displayed so as to be distinguished.

  Next, the operation acquisition unit 508 determines whether or not to end the security setting due to the pressing of the clear key or the like (S702). When the operation acquisition unit 508 determines to end the security setting (Yes in S702), the control unit 50 ends the display of the security setting screen.

  On the other hand, if the operation acquisition unit 508 determines not to end the security setting (No in S702), the operation acquisition unit 508 determines whether the icon has been dropped on the image file with position information (S703).

  When the operation acquisition unit 508 determines that the icon has not been dropped on the image file with position information (No in S703), the display control unit 507 controls the display unit 40 to continue displaying the security setting screen ( S701).

  On the other hand, when the operation acquisition unit 508 determines that the icon has been dropped onto the image file with position information (see FIG. 16B) (Yes in S703), the security setting unit 510 indicates that the dropped icon indicates Based on the security setting information, the security setting information is stored in the management table shown in FIG. 3A (S704).
