A configuration may be adopted in which the display control unit displays the file by setting information indicating that the display is possible in the display attribute information.

  According to said structure, the information which shows that display is possible is set to the display attribute information of the file used as initialization object.

  Therefore, the file can be displayed on the display unit.

  Therefore, it is possible to easily return to the original use state before initialization.

  The information processing terminal may be realized by a computer. In this case, a control program for the information processing terminal for causing the information processing terminal to be realized by the computer by causing the computer to operate as each means, and A computer-readable recording medium on which it is recorded also falls within the scope of the present invention.

  The information processing terminal 1A is typically a mobile terminal such as a mobile phone or a smartphone, but is not limited thereto.

  Hereinafter, among users who use the information processing terminal 1A, users who use the information processing terminal 1A in a regular manner are referred to as “regular users”. An authorized user is a user who uses his / her IC card in the information processing terminal 1A and uses the information processing terminal 1A. On the other hand, a user who illegally uses the information processing terminal 1A of a regular user is referred to as “illegal user”. An unauthorized user is a user who uses an information processing terminal 1A by attaching an IC card other than a regular user to the information processing terminal 1A. When a regular user and an unauthorized user are not distinguished, they are simply written as “user”.

(Configuration of information processing terminal)
The configuration of the information processing terminal 1A will be described with reference to FIG. FIG. 1 is a block diagram showing a configuration of the information processing terminal 1A. As shown in the figure, the information processing terminal 1A includes a control unit 10A, a storage unit 20A, a card reading unit 30, a display unit 40, and an operation unit 50.

  First, the control unit 10A performs overall control of the information processing terminal 1A, and can be configured by, for example, a CPU (Central Processing Unit). The control unit 10A controls each of the storage unit 20A, the card reading unit 30, the display unit 40, and the operation unit 50. The detailed configuration of the control unit 10A will be described later.

  Next, the storage unit 20A (1) a control program for each unit executed by the control unit 10A, (2) an OS program, (3) an application program, and (4) various data read when executing these programs. It is something to remember. The storage unit 20A is configured by a nonvolatile storage device such as a flash memory. Further, the storage unit 20A is configured by a volatile storage device such as a RAM (Random Access Memory) as a work area for temporarily storing data in the process of executing the above-described various programs by the control unit 10A. Has an area.

  The storage unit 20A is not necessarily provided in the information processing terminal 1A. The information processing terminal can be accessed as an external storage device that can be attached to and detached from the information processing terminal 1A or an external storage device on a communication network. The structure connected to 1A may be sufficient.

  The storage unit 20A particularly includes an identification information storage unit 21 and a user data storage unit (storage unit) 22, as shown in FIG.

  The identification information storage unit 21 is a storage area for storing identification information (second identification information) (hereinafter referred to as regular identification information) of an IC card of an authorized user who uses the information processing terminal 1A.

  The user data storage unit 22 is an area for storing various files (hereinafter also referred to as user data) acquired and generated by the user using various functions and various applications provided in the information processing terminal 1A. A typical example of the file is an image captured by an imaging unit (not shown), voice recorded by a recording unit (not shown), mail data acquired / generated by an email application (not shown), and a document editing application (not shown). Document file, etc.

  Next, the card reading unit 30 reads information from an IC card attached to the information processing terminal 1A. In the present embodiment, in particular, identification information (first identification information) (hereinafter referred to as current identification information) of an IC card attached to the information processing terminal 1A is read.

  Next, the display unit 40 is a display device that displays an image based on an instruction from the control unit 10A. An LC (Liquid Crystal) display panel, an EL (Electro Luminescence) display panel, or the like can be used as the display unit 40. Although not shown, the control unit 10A or the display unit 40 is appropriately provided with a configuration necessary for displaying an image such as a VDP (Video Display Processor) and a VRAM (Video RAM).

  The display unit 40 is not necessarily provided inside the information processing terminal 1A, and may be configured as an external device. In this case, the information processing terminal 1A and the display unit 40 are connected by a cable that performs image transmission, such as a high definition multimedia interface (HDMI) cable, a digital visual interface (DVI) cable, or the like.

  Next, the operation unit 50 receives an operation performed by the user on the information processing terminal 1A. The operation unit 50 is not particularly limited as long as the user can perform a desired operation, and may be a key provided on the surface of the main body of the information processing terminal 1A or a remote control. Further, in the case where the display unit 40 is a touch panel having both functions of image display and operation input, the display unit 40 may be configured to also function as the operation unit 50.

(Configuration of control unit)
Next, the control unit 10A will be described in detail. The control unit 10A includes an activation processing unit 11, an identification information verification unit (identification information verification unit) 12, an initialization processing unit (initialization unit) 13, a display control unit (display control unit) 15, and a file protection release unit (protection). Release means) 16.

  The activation processing unit 11 executes various processes for activating the information processing terminal 1A when the information processing terminal 1A is powered on.

  Next, the identification information collation unit 12 collates the current identification information read by the card reading unit 30 with the regular identification information stored in the identification information storage unit 21, and determines whether or not they match. To do.

  If the two match, it can be said that the information processing terminal 1A is being used by an authorized user. On the other hand, if the two do not match, it can be said that the information processing terminal 1A is being used by an unauthorized user.

  The verification process by the identification information verification unit 12 is typically called automatically during the startup process by the startup processing unit 11, but is automatically called during the initialization process by the initialization processing unit 13. Also good.

  Next, the initialization processing unit 13 executes an initialization process for deleting a file to be initialized stored in the storage unit 20A. The files to be initialized are typically various files stored in the user data storage unit 22.

  The initialization processing by the initialization processing unit 13 may be started when a user operation for instructing initialization is received by the operation unit 50, or is automatically called during the startup processing by the startup processing unit 11. May be.

  The initialization processing unit 13 displays a confirmation screen on the display unit 40 for confirming to the user whether or not the initialization can be performed before executing the initialization process and deleting the file. It is desirable to have a configuration that

  The initialization processing unit 13 further includes a file protection unit (file protection means) 14. When the current identification information and the regular identification information do not match as a result of the collation by the identification information collation unit 12, the file protection unit 14 causes the user data storage unit 22 to perform the initialization process without executing the initialization process. Control to prevent access to the stored file itself. As a result, it looks as if the initialization process has been executed for an unauthorized user, and the file stored in the user data storage unit 22 is protected.

  Various methods are conceivable as a method of controlling the access to the file itself so that it cannot be accessed. Typically, a method of hiding the file itself so that it cannot be seen by unauthorized users is preferable. When display attribute information indicating whether or not a file can be displayed is managed, the file protection unit 14 displays information indicating that the file stored in the user data storage unit 22 cannot be displayed when the file is hidden. Set in display attribute information. As a result, the file stored in the user data storage unit 22 is not displayed on the display unit 40 under the control of the display control unit 17 described later, and access to the file itself becomes impossible.

  The display attribute information indicating whether the file can be displayed may be managed for each file as (1) attribute information associated with the file, or (2) managed as attribute information associated with the user data storage unit 22. Alternatively, (3) it may be managed as information held in a holding unit such as a register that can be referred to by the display control unit 17.

  Other methods for controlling the access to the file itself to be inaccessible include a method of moving a file stored in the user data storage unit 22 to a storage unit that cannot be accessed by the user, or an access from the user. A method to treat it as an impossible “hidden file” can be considered.

  Next, when the current identification information matches the regular identification information as a result of the verification by the identification information verification unit 12, the file protection cancellation unit 19 accesses the file itself that has been disabled by the file protection unit 14 Is controlled to be possible.

  In other words, when the information processing terminal 1A returns to a situation where it is used by an authorized user, if the access to the file itself stored in the user data storage unit 22 is disabled, it can be accessed. And unprotect the file. As described above, when the display attribute information indicating whether or not a file can be displayed is managed, it is preferable to display the hidden file so that the file can be seen by the user.

  In this case, the file protection cancellation unit 19 sets information indicating that the file stored in the user data storage unit 22 can be displayed in the display attribute information when displaying the file. Thus, the file stored in the user data storage unit 22 is displayed on the display unit 40 under the control of the display control unit 17 described later.

  Next, the display control unit 17 controls whether or not to display the file on the display unit 40 in accordance with the display attribute information of the file. Specifically, when the display attribute information of the file indicates that it can be displayed, the display control unit 17 controls the display unit 40 to display the file. On the other hand, when the display attribute information of the file indicates that display is not possible, the display control unit 17 controls not to display the file on the display unit 40.

(Processing flow in information processing terminal)
Next, an example of the flow of processing in the information processing terminal 1A will be described with reference to FIG. FIG. 2 is a flowchart illustrating an example of a process flow in the information processing terminal 1A.

  First, when the activation processing by the activation processing unit 11 is started when the power of the portable information terminal 1A is turned on in the state where the IC card is mounted on the portable information terminal 1A (step (hereinafter, simply “S”). 11), the identification information collation unit 12 collates the current identification information read by the card reading unit 30 with the regular identification information stored in the identification information storage unit 21 (S12 (identification information)). Matching step)).

  If the two do not match (“does not match” in S12), the initialization processing unit 13 displays a confirmation screen on the display unit 40 to confirm to the user whether or not the initialization may be executed. (S13).

  If initialization is selected on the confirmation screen (YES in S14), the file protection unit 14 stores the file stored in the user data storage unit 22 without deleting the file to be initialized. Control to prevent access to itself. Specifically, the file protection unit 14 stores the information stored in the user data storage unit 22 by setting information indicating that the file stored in the user data storage unit 22 cannot be displayed in the display attribute information. The hidden file is hidden (S15 (file protection step)).

  Thereafter, the startup process started in step S11 is continued (S16). Even when it is selected not to initialize on the confirmation screen (NO in S14), the startup process started in step S11 is continued (S16).

  On the other hand, when the current identification information read by the card reading unit 30 matches the regular identification information stored in the identification information storage unit 21 (“match” in S12), the current identification information is stored in the user data storage unit 22. If access to the file itself is impossible (YES in S17), the file protection release unit 19 controls the access to the file itself that has been made inaccessible. Specifically, the file protection cancellation unit 19 stores information indicating that the file stored in the user data storage unit 22 can be displayed in the display attribute information, thereby storing the file in the user data storage unit 22. The file being displayed can be displayed on the display unit 40 (S18).

  Thereafter, the startup process started in step S11 is continued (S16). Even if the file stored in the user data storage unit 22 is not in an inaccessible state (NO in S17), the startup process started in step S11 is continued (S16).

(Effects produced by this embodiment)
As described above, according to the configuration of the information processing terminal 1A, even when the initialization process is started when the information processing terminal 1A is being used by an unauthorized user, the information processing terminal 1A is stored in the user data storage unit 22. Access to the file is disabled. Therefore, while it is possible to prevent the file from being actually erased, it can appear to an unauthorized user as if it had been initialized.

  Furthermore, since the file can be accessed when the information processing terminal 1A is used by a legitimate user, the original use state before initialization can be easily restored.

[Reference form]
By the way, if an unauthorized user realizes that the countermeasures against unauthorized use are taken, the unauthorized user may turn off the information processing terminal, and the information processing terminal may be left to run out of battery power. The possibility increases. In the case of a mobile phone, if the power is turned off or the remaining battery power is exhausted, information on the mobile phone cannot be updated on the communication network side, so even a telecommunications carrier can specify the location of the mobile phone. It becomes difficult. As a result, it becomes difficult to find a mobile phone used by an unauthorized user, and the possibility of returning to a legitimate user is reduced.

  Therefore, a reference form for solving the above problem will be described with reference to FIGS. In addition to the configuration of the information processing terminal 1A described above, the information processing terminal 1B according to the present embodiment includes data indicating the location and situation where the information processing terminal 1B is used by an unauthorized user (hereinafter also referred to as situation data). ) Is transmitted to a preset notification destination without being understood by an unauthorized user.

  Furthermore, the processing of step 21 and step S22 may be executed in parallel with the processing of steps S11 to S15.

(Effects produced by this reference form)
As described above, according to the configuration of the information processing terminal 1B, when the unauthorized user inserts the unauthorized user's IC card and activates the information processing terminal 1B, the unauthorized user's IC card is contacted from the unauthorized user's IC card. Along with the identified telephone number, status data including at least one of image, sound, and positioning information is transmitted.

  Therefore, the authorized user can know early that the lost information processing terminal 1B is being used by an unauthorized user.

  Furthermore, there is a high possibility that the location of the information processing terminal 1B can be determined based on the transmitted telephone number and status data.

  Furthermore, since the communication carrier can confirm where the unauthorized user's IC card is used because it is connected to the communication network, the possibility of specifying the location of the information processing terminal 1B is increased.

  Furthermore, since the situation data can be transmitted without being noticed by the unauthorized user, the possibility that the unauthorized user continues to use the information processing terminal 1B increases. If it continues to be used, it is considered that an unauthorized user periodically charges the information processing terminal 1B, so that it is also possible to avoid running out of power due to the remaining battery level. Therefore, since possibility of pinpointing the position of a portable information terminal can be raised, it becomes easy to find the portable information terminal used by the unauthorized user, and possibility that it will return to a regular user's hand will become high.

(Modification)
In the reference form described above, the information processing terminal 1B is configured to include both a function relating to initialization and a function relating to transmission of status data. However, since both functions are independent of each other, both functions are not necessarily provided. It is not necessary to prepare at the same time. That is, a configuration having only a function related to transmission of status data may be used.

[Additional Notes]
Finally, each block (particularly, the control units 10A and 10B) of the information processing terminals 1A and 1B may be configured as hardware by a logic circuit formed on an integrated circuit (IC chip). Alternatively, it may be realized by software using a CPU.

  When implemented by software, the information processing terminals 1A and 1B include a CPU that executes instructions of a control program that implements each function, a ROM (read only memory) that stores the program, and a RAM (random access) that develops the program. memory), a storage device (recording medium) such as a memory for storing the program and various data. An object of the present invention is a record in which a program code (execution format program, intermediate code program, source program) of a control program of the information processing terminals 1A and 1B, which is software that realizes the above-described functions, is recorded in a computer-readable manner. This can also be achieved by supplying a medium to the information processing terminals 1A and 1B and reading and executing the program code recorded on the recording medium by the computer (or CPU or MPU).

  Examples of the recording medium include tapes such as magnetic tapes and cassette tapes, magnetic disks such as floppy (registered trademark) disks / hard disks, and disks including optical disks such as CD-ROM / MO / MD / DVD / CD-R. IC cards (including memory cards) / optical cards, semiconductor memories such as mask ROM / EPROM / EEPROM / flash ROM, logic circuits such as PLD (Programmable Logic Device), etc. it can.

  The information processing terminals 1A and 1B may be configured to be connectable to a communication network, and the program code may be supplied via the communication network. The communication network is not particularly limited. For example, the Internet, intranet, extranet, LAN, ISDN, VAN, CATV communication network, virtual private network, telephone line network, mobile communication network, satellite communication. A net or the like is available. Further, the transmission medium constituting the communication network is not particularly limited. For example, even in the case of wired such as IEEE 1394, USB, power line carrier, cable TV line, telephone line, ADSL line, etc., infrared rays such as IrDA and remote control, Bluetooth ( (Registered trademark), IEEE802.11 radio, HDR (High Data Rate), NFC (Near Field Communication), DLNA (Digital Living Network Alliance), mobile phone network, satellite line, terrestrial digital network, etc. .

  Thus, in this specification, the means does not necessarily mean physical means, but includes cases where the functions of the means are realized by software. Further, the function of one means may be realized by two or more physical means, or the functions of two or more means may be realized by one physical means.
