  Flg A 46, flg B 47, and flg C 48 are storage means each having a capacity of 1 bit. That is, flg A 46, flg B 47, and flg C 48 can store only two values of 0 or 1.

  The private data storage unit 49 (private data storage means) stores private data. Private data means, for example, telephone directory data, schedule data, image data, video data, outgoing / incoming history data, and the like.

  Next, the operation of the mobile phone 1 will be described with reference to FIGS. Note that the values of flgA46, flgB47, and flgC48 are set to 0 when the cellular phone 1 is powered on.

  First, in FIG. 4, when the cellular phone 1 is powered on (S100), the CPU 8 causes the first timer 24 to start measuring time (S110). Then, the CPU 8 once initializes the first timer 24 (S120). Next, the CPU 8 checks whether or not the movement detector 28 has detected movement of the mobile phone body 17 (S130). If the movement detector 28 has not detected the movement of the mobile phone body 17 (S130: YES), the CPU 8 compares the time measured by the first timer 24 with the first predetermined time (S140). If the time measured by the first timer 24 has reached the first predetermined time (S140: YES), the first loss determination unit 30 determines that the mobile phone 1 itself has been lost and performs the loss process. (S150).

  On the other hand, if the movement detection unit 28 detects the movement of the mobile phone body 17 in S130 (S130: NO), the first timer initialization unit 29 initializes the first timer 24 (S120). In S140, if the time measured by the first timer 24 has not reached the first predetermined time (S140: NO), the process returns to S130.

  In short, the first loss determination unit 30 determines that the mobile phone 1 itself has been lost when the first predetermined time has elapsed since the last movement of the mobile phone body 17 was detected. According to the above control flow, it is possible to detect the loss of the mobile phone 1 itself.

  Next, in FIG. 5, it is assumed that an incoming call occurs (S200). First, the CPU 8 checks whether flgA 46 is 0 (S210). When the value of flgA 46 is 0 (S210: YES), the second timer starting unit 31 causes the second timer 25 to start measuring time (S220). If the user does not respond to the incoming call (S240: YES), the CPU 8 sets the value of flgA 46 to 1 (S250). Subsequently, the CPU 8 determines whether the keyboard 12 has been operated (S260). If the keyboard 12 is not operated (S260: YES), the CPU 8 compares the time measured by the second timer 25 with the second predetermined time (S270). If the time measured by the second timer 25 has reached the second predetermined time (S270: YES), the second loss determination unit 33 determines that the mobile phone 1 itself has been lost and performs the loss process. (S280).

  On the other hand, when the value of flgA 46 is not 0 in S210 (S210: NO), the CPU 8 ends the process (S230). In S240, when the user responds to the incoming call (S240: NO), the second timer stop unit 32 stops the time measurement by the second timer 25 (S290), resets the second timer 25, and the CPU 8 Sets the value of flgA46 to 0 (S295) and ends the process (S296). In S260, when the keyboard 12 is operated (S260: NO), the second timer stop unit 32 stops the time measurement by the second timer 25 (S290), resets the second timer 25, and the CPU 8 , FlgA46 is set to 0 (S295), and the process is terminated (S296). In S270, if the time measured by the second timer 25 has not reached the second predetermined time (S270: NO), the process returns to S260.

  In short, the second loss determination unit 33 determines that the mobile phone 1 is in a lost state if there is no response from the user for a second predetermined time after a call has been received. According to the above control flow, it is possible to detect the loss of the mobile phone 1 itself.

  Next, in FIG. 6, it is assumed that an incoming mail has occurred (S300). First, the CPU 8 checks whether flgB47 is 0 (S310). When flgB47 is 0 (S310: YES), the third timer starting unit 34 causes the third timer 26 to start measuring time (S320). Then, the CPU 8 sets the value of flgB47 to 1 (S340). Subsequently, the CPU 8 determines whether the keyboard 12 has been operated (S350). If the keyboard 12 is not operated (S350: YES), the CPU 8 compares the time measured by the third timer 26 with the third predetermined time (S360). If the time measured by the third timer 26 has reached the third predetermined time (S360: YES), the third loss determination unit 36 determines that the mobile phone 1 itself has been lost and performs the loss process. (S370).

On the other hand, if the value of flgB47 is not 0 in S310 (S310: NO), the CPU 8 ends the process (S330). In S350, when the keyboard 12 is operated (S350: NO), the third timer stop unit 35 stops the time measurement by the third timer 26 (S380), resets the third timer 26, and the CPU 8 , FlgB47 is set to 0 (S390), and the process is terminated (S395).
In S360, if the time measured by the third timer 26 has not reached the third predetermined time (S360: NO), the process returns to S350.

  In short, the third loss determination unit 36 determines that the mobile phone 1 itself is in a lost state if there is no response from the user for a third predetermined time after an incoming mail. According to the above control flow, it is possible to detect the loss of the mobile phone 1 itself.

  Next, in FIG. 7, the control flow of the loss process will be described. First (S400), the CPU 8 checks whether the value of flgC48 is 0 (S410). If the value of flgC48 is 0 (S410: YES), the fourth timer starting unit 37 causes the fourth timer 27 to start measuring time (S420). Further, the CPU 8 sets the value of flgC48 to 1 (S440). Next, the access prohibition unit 40 protects the private data by making the private data inaccessible (S450). Then, the loss notification unit 41 transmits a loss notification email to another email address owned by the user (S460). Next, the CPU 8 determines whether a release mail has been received (S470). When the cancellation mail has not been received (S470: YES), the CPU 8 compares the time measured by the fourth timer 27 with the fourth predetermined time (S480). If the time measured by the fourth timer 27 has reached the fourth predetermined time (S480: YES), the private data erasure unit 42 transmits the private data to a predetermined server and saves it (S490). The target data is deleted (S500), and the process is terminated (S501).

  On the other hand, if the value of flgC48 is not 0 in S410 (S410: NO), the process ends (S430). In S470, when the release mail is received (S470: NO), the fourth timer stop unit 38 stops the time measurement by the fourth timer 27 (S510), and the CPU 8 sets flg A 46, flg B 47, and flg C 48. Each value is set to 0 (S520), the protection of private data is released (S530), the private data is returned to an accessible state, and the process is terminated (S501). In S480, when the time measured by the fourth timer 27 has not reached the fourth predetermined time (S480: NO), the process returns to S470.

  In short, since the private data is erased when the mobile phone 1 itself is lost, it is possible to prevent the private data from being viewed by a third party when lost. . In addition, since the private data is saved in advance before erasing the private data, the user can reacquire the private data as necessary.
