  FIG. 1 is a schematic configuration diagram of a mobile phone terminal 1 according to a preferred embodiment of the present invention. As shown in FIG. 1, the cellular phone terminal 1 according to the present embodiment includes a data input function for creating and saving moving image data and text data used for e-mail transmission / reception, a voice communication function, and e-mail. This is a portable terminal device having a data communication function such as a transmission / reception function and a data display function related to telephone directory data, schedule data, moving image data, and the like. The present invention is not limited to a mobile phone terminal having such a communication function, and can be widely applied to information processing terminals such as a PDA and a portable personal computer that do not have a communication function.

  The cellular phone terminal 1 includes, as functional components, an input unit 11, a location information acquisition unit 12, a stored data storage unit (data storage unit) 13, a schedule information storage unit (schedule data storage unit) 14, A mode switching unit 15, a data display control unit 16, an information display unit (information display unit) 17, a saved data identification unit (saved data identification unit) 18, and a location information storage unit (location information storage unit) 19 And a storage data setting unit (storage data setting means) 20. Hereinafter, each component of the mobile phone terminal 1 will be described in detail.

  The input unit 11 is a part that receives data input and instruction input from a user or a communication network, and includes an input key, a touch panel, a keyboard, an imaging unit such as a digital camera unit, a wireless communication module, and the like. That is, the input unit 11 receives input of text data that is e-mail transmission data from a user and receives text data that is e-mail reception data using an e-mail reception function. The input unit 11 receives input of moving image data captured by the user using the imaging unit. The input unit 11 also receives an instruction input for setting a predetermined operation or operation mode from the user. Further, when receiving input of moving image data, the input unit 11 adds time information indicating an imaging time and location information indicating an imaging location to the moving image data. This location information is acquired by the location information acquisition unit 12 having a GPS (Global Positioning System) positioning function or a positioning function using the base station information in the communication network, and is passed to the input unit 11.

  Then, the input unit 11 stores the e-mail transmission data and moving image data created by the user and the received e-mail reception data together with the index data created for searching the saved data, each time the saved data Store in the storage unit 13. FIG. 2 is a diagram showing the configuration of the index data stored in the saved data storage unit 13. FIG. 2 (a) shows the configuration of the index data for moving image data, and FIG. The structure of the index data for e-mail transmission data is shown. As shown in FIG. 2A, the index data for moving image data includes data “date and time: 2010/2/2 12:00” indicating the date and time when the moving image was captured, and data indicating the imaging location “ The file name of the moving image data is “GPS location information: Akihabara” and data “secret flag: OFF” indicating whether or not the stored data is set in a secret state during normal mode (details will be described later). Saved as a data record associated with “file name: aaa.jpg”. Further, as shown in FIG. 2B, the index data for the e-mail transmission data includes e-mail transmission data “date / time: 2010/2/2 10:30” indicating the date and time when the e-mail was transmitted. The title name data “Title: Patent Review Meeting” in the data, the word data extracted from the e-mail transmission data “Body Extracted Words: Akiba, XXX Bill”, and whether or not the stored data is set in a secret state This data “secret flag: OFF” is stored as a data record associated with each other.

  Furthermore, the input unit 11 creates schedule data indicating the user's action schedule according to data input from the user, and stores the schedule data in the schedule information storage unit 14. FIG. 3 is a diagram showing a configuration of schedule data stored in the schedule information storage unit 14. As shown in the figure, the schedule data includes information “date and time: 2010/2/2 10:00 to 15:00” indicating a time zone corresponding to the schedule and information “schedule content: “Training” and information “place: Akihabara” indicating the place where the action is performed are stored as mutually associated data.

  Returning to FIG. 1, the data display control unit 16 stores the stored data in order to display the data stored in the stored data storage unit 13 on the information display unit 17 such as a display device in response to an instruction input from the user. The data read from the unit 13 is converted into a data format that can be displayed on the information display unit 17 and output to the information display unit 17. For example, the data display control unit 16 displays a menu screen for displaying a menu item for selecting processing contents in response to a user instruction input, and displays e-mail data or a moving image from the displayed menu items. When an instruction input for selecting display of image data is received, e-mail data or moving image data is read from the stored data storage unit 13 and displayed. More specifically, the data display control unit 16 displays a list of folders in the storage data storage unit 13 that stores moving image data in response to an instruction input by the user, and then inputs an instruction to select a specific folder from the user. Is received, the moving image data stored in the specific folder is displayed in a list. Further, the data display control unit 16 displays a list of e-mail transmission data and e-mail reception data in response to an instruction input from the user, and accepts an instruction input for selecting specific e-mail data from the list. If it is, the detailed contents of the e-mail data are displayed.

  Here, the data display control unit 16 limits the data to be displayed on the information display unit 17 in accordance with the data display mode set by the mode switching unit 15 described later. Specifically, when the mode set by the mode switching unit 15 is a secret mode that allows data to be freely viewed, the data display control unit 16 stores stored data in response to an instruction input from the user. All data stored in the unit 13 can be displayed. On the other hand, when the mode set by the mode switching unit 15 is a normal mode that restricts data browsing, the data display control unit 16 is designated in advance for an instruction input from the user. Data other than specified data can be displayed. More specifically, the data display control unit 16 refers to the index data (FIG. 2) stored in the storage data storage unit 13, and the storage data in which the secret flag included in the index data is set to “ON”. With respect to, by controlling the output to the information display unit 17, the stored data is controlled so as not to be browsed. In this case, when a list display of moving image data or e-mail data is requested, the data display control unit 16 displays a list of stored data excluding stored data whose browsing is restricted. This makes it impossible to display the non-browsing target moving image data in an enlarged manner or to display the detailed contents of the non-browsing target e-mail data.

  The mode switching unit 15 switches the data display mode between the secret mode and the normal mode in response to an instruction input instructing mode switching from the user. That is, when the switching from the normal mode to the secret mode is instructed, the mode switching unit 15 receives the input of authentication information such as a password from the user and executes user authentication. Then, when the user authentication is successful, the mode switching unit 15 switches the data display mode from the normal mode to the secret mode, and sets the data display mode of the data display control unit 16 accordingly. In addition, when the switching from the secret mode to the normal mode is instructed, the mode switching unit 15 switches the data display mode of the data display control unit 16 without requesting authentication information from the user.

  The stored data specifying unit 18 stores the location information and time information included in the schedule data stored in the schedule information storage unit 14 and the location information included in the stored data when storing the stored data in the stored data storage unit 13. The stored information in which the location information and the time information do not match is specified by collating with the time information. That is, the saved data specifying unit 18 reads schedule data in which a time zone including the time indicated by the date and time information included in the index data stored in the saved data storage unit 13 is set from the schedule information storage unit 14. Further, the saved data specifying unit 18 determines whether or not the location information included in the read schedule data matches the location information included in the index data corresponding to the corresponding saved data. Then, the storage data specifying unit 18 delivers information (for example, the file name of the moving image data, the date and time of the e-mail data, and the title) specifying the storage data whose location information and time information do not match to the storage data setting unit 20. .

  For example, when data as shown in FIGS. 2A and 3 is targeted, the saved data specifying unit 18 includes a time zone including the date and time “2010/2/2 12:00” included in the index data. Read the schedule data corresponding to “2010/2/2 10: 00-15: 00”. Then, the stored data specifying unit 18 compares the location information “Akihabara” included in the schedule data with the location information “Akihabara” included in the index data, and determines that they are “match”. On the other hand, when the data as shown in FIGS. 2B and 3 is targeted, the saved data specifying unit 18 includes a time zone including the date and time “2010/2/2 19:30” included in the index data. Read the schedule data corresponding to “2010/2/2 18: 00-22: 00”. Then, the stored data specifying unit 18 determines that the location information “Ginza” included in the schedule data and the location information “Gion, Maiko, XX bun” included in the index data are “mismatched”. To do. At this time, when the e-mail data is targeted as the saved data, the saved data specifying unit 18 selects location information from the data of the “title” and “text extracted word” of the index data.

  The stored data specifying unit 18 performs processing based on hierarchical data stored in advance in the location information storage unit 19 when collating the location information included in the schedule data with the location information included in the stored data. To do. FIG. 4 shows an example of the structure of the hierarchical data stored in the location information storage unit 19. As shown in the figure, in the location information storage unit 19, a plurality of location information including “Layer 1: Tokyo”, “Layer 2: Akihabara”, and “Layer 3: Akiba, XXX Building, Otaku” are hierarchical. Stored in association with. Therefore, the saved data specifying unit 18 determines that the location information matches when two pieces of location information included in the schedule data and the saved data are associated with each other in the hierarchical data. For example, if the location information is “Akiba” and “Otaku”, they belong to the same upper layer “Layer 2: Akihabara”, so that they are determined to match. Further, when the location information is “XXX building” and “Akihabara”, it is determined that the upper layer and the lower layer are related to each other because they are related to each other and are matched.

  Returning to FIG. 1, the saved data setting unit 20 sets the saved data specified by the saved data specifying unit 18 so that it cannot be viewed on the information display unit 17. Specifically, the saved data setting unit 20 searches the saved data storage unit 13 for index data corresponding to the saved data specified by the saved data specifying unit 18, and sets the secret flag included in the corresponding index data to “ON”. Update to "".

  Next, referring to FIG. 5, the operation of the mobile phone terminal 1 will be described, and the data browsing control method in the mobile phone terminal 1 will be described in detail. FIG. 5 is a flowchart showing an operation at the time of saving the saved data by the mobile phone terminal 1.

  First, when saved data such as e-mail data and moving image data is created by the input unit 11 and stored in the saved data storage unit 13, search of schedule data is started when triggered (step S101). Then, schedule data including time information that matches the time information included in the saved data is extracted from the schedule information storage unit 14 by the saved data specifying unit 18 (step S102). Thereafter, the stored data specifying unit 18 collates the location information included in the extracted schedule data with the location information included in the stored data (step S103).

  If the location information does not match as a result of the above collation (step S103; NO), the stored data setting unit 20 sets the secret flag of the corresponding stored data to “ON”, and the stored data is viewed in the normal mode. Is set to an impossible state (step S104). On the other hand, when the location information matches (step S103; YES), the operation is performed so as not to update the secret flag of the corresponding stored data.

  Next, it is determined whether or not there is other schedule data that matches the time information included in the stored data (step S105). If there is other schedule data (step S105; NO), the next After the schedule data is read (step S106), the processes of steps S102 to S104 are repeated. If there is no other schedule data (step S105; YES), the storage process for the corresponding storage data is terminated.

  According to the mobile phone terminal 1 described above, schedule data including location information and time information is stored in the schedule information storage unit 14 in advance, and the stored data stored in the storage data storage unit 13 is stored by the storage data specifying unit 18. The stored data whose location information and time information included in the stored data do not match the schedule data is specified from among the stored data, and the specified stored data cannot be viewed on the information display unit 17 by the stored data setting unit 20. Is set to the correct state. As a result, browsing of stored data accompanying actions deviating from a preset schedule is automatically restricted. As a result, by appropriately determining the level of confidentiality based on the schedule information, it is possible to easily prevent browsing of stored data with high confidentiality by a third party.

  In addition, when the stored data specifying unit 18 determines that the location information matches, it determines whether the two location information is hierarchically associated with each other based on the hierarchical data stored in the location information storage unit 19. Therefore, it is possible to appropriately determine the location relationship between the schedule data and the stored data.

  In addition, this invention is not limited to embodiment mentioned above. For example, the timing at which the saved data and the schedule data are collated is not limited to when the saved data is created. For example, the collation processing by the saved data specifying unit 18 may be periodically activated for the saved data stored in the saved data storage unit 13. Further, the collation process may be started at a timing when an instruction input from the user is received via the input unit 11.
