  A CPU 22 includes a ROM 24 that stores various programs and the like, and a RAM 26 that provides a work area to be used when the CPU 22 executes various programs. A memory such as a flash ROM 28 for storing the user's password and operation prohibition state information indicating the operation prohibition state, other information necessary for the mobile phone, and a VRAM 30 for storing image information captured from the camera function are used as memories. . Reference numeral 32 denotes a data processing unit when the cellular phone 2 is lost to realize the operation of the embodiment.

  FIG. 2 shows the configuration of the data processing unit 32 when lost. In the embodiment, when the mobile phone 2 is lost, a predetermined command and password are transmitted from a new mobile phone, a support center, a personal computer, etc. to the lost mobile phone 2 using e-mail or the like. The data processing unit 32 refers to the command search unit 40 for searching for a command from the received mail header and the like, the command list 44 and the like, and detects a predetermined command transmitted when the mobile phone is lost. A command analysis unit 42 is provided. In the embodiment, a plurality of lost commands are provided as will be described later, and different operation prohibition processing is performed for each command.

  The data processing unit 32 uses a password storage buffer 48, and a password verification unit 46 for verifying whether the received password is correct, or internal information for transmitting internal information of the mobile phone 2 if the passwords match. A transmission unit 50 and an operation prohibition processing unit 52 that performs processing for setting an operation prohibition state according to the received command are provided. Here, the transmission destination of the internal information is a sender of the received mail, a support center, a mail address of a predetermined transmission destination designated by a command, or the like. A transmission information table 60 for storing internal information to be transmitted is shown in FIG. 3, and leakage prohibition information (area A) is included as a lock information in a part of each information. After the transmission information is transmitted, the operation prohibition processing unit 52 performs processing such as prohibiting power-on or not displaying the lock information according to the command. The command list 44, password storage buffer 48, and transmission information table 60 are stored in a flash ROM or the like.

  FIG. 3 shows the transmission information table 60. Area A and area B are provided in table 60, lock information for prohibiting leakage is stored in area A, and setting information for user convenience is stored in area B. Information included in the table 60 as transmission information can be arbitrarily determined. In the embodiment, all the information in the table 60 is transmitted to a predetermined destination. However, in the operation prohibiting process, for example, processing for making the information on the area A impossible to display and making the information on the area B displayable is performed. That is, the transmission information table 60 includes information that is convenient for the user but should not be leaked to others (area A), and information that can be seen by others as information for convenience (area B). Each is provided separately to perform different processing. Further, for example, the information on the area A may be deleted without being transmitted, and only the information on the area B, which is information for the user's convenience, may be transmitted. Note that the transmission information and the information to be deleted may be specified by a command.

  The operation of the embodiment will be described with reference to FIGS. In FIG. 4, when a mobile phone is lost, stolen, etc., the mail address, command, and password of the mobile phone etc. are written in the header and body text of the new mobile phone, the support center, the mobile phone lost from the personal computer, etc. To send mail (steps S1 to S4). The mail transmission is repeated at predetermined intervals until the connection is successful. The mobile phone automatically receives the mail when the power is turned on. This may be provided as a standard function of the mobile phone, or may be set by the user himself.

  When the connection is successful, a command, a password, and the like are transmitted (steps S3 and S4), and the lost cellular phone receives these (step S5). If the received mail contains a command related to loss (step S6) and the passwords match (step S7), the internal information shown in FIG. 3 is transmitted to the mail sender (steps S8 and S9). Next, in accordance with the status setting command, processing for prohibiting the operation of the lost mobile phone, erasing internal information, and the like are performed, and the operation is disabled (steps S10 and S11). When the internal information is transmitted to a support center, a personal computer, or the like, the user can obtain the same usability without performing an operation such as resetting by downloading the internal information to a new mobile phone.

  Next, FIG. 5 shows internal information transmission processing (step S8 in FIG. 4), and FIG. 6 shows operation prohibition processing. In FIG. 5, the lost mobile phone obtains the mail address of the information transmission destination from the received electronic mail or the like (step S20), and the transmission information stored in the transmission information table of FIG. (Steps S21 and S22). At this time, a transmission information address table (not shown) storing the addresses of the individual transmission information is provided to be referred to, and the transmission information is obtained from the stored addresses and transmitted to the destination mail address or the like. It is good to do.

FIG. 6 shows a process for setting the operation prohibited state defined for each state setting command. In this process, the memory management after the transmission of the internal information and the state of the mobile phone are set. In the figure, for example, when there is no possibility that the mobile phone can be found due to theft or the like, by sending a command: XXXX, all the memories are erased and the power ON is set to an impossible state. Command: AAAA can be turned on, but in order to prevent unauthorized use by a third party, the lock information (information in area A in FIG. 2) is deleted and the entered passwords match. However, lock information cannot be displayed and communication functions cannot be used. However, there is no particular problem even if the setting information related to usability (information in area B in FIG. 3) is displayed.
In the command: BBBB, the power is turned on, and if the entered passwords match, it is made available again. If the mobile phone cannot be found temporarily but it is likely that it will come out, it can be temporarily relieved by temporarily disabling it with this command. If the mobile phone is found, the operation prohibition state can be canceled by inputting the password, and the mobile phone can be used again.

  These commands can be selected according to the state in which the mobile phone is lost. For example, the command: BBBB can be transmitted when it is not found now but there is a high possibility that it has been left somewhere in the house, and the command: XXXX can be transmitted when it is stolen.

As described above, according to the embodiment, in case of loss or theft, the user can collect necessary information by sending and receiving emails, and can maintain the user-friendliness up to that time without the need for resetting with a new mobile phone. . After the user has obtained the necessary information, unauthorized use can be prevented by prohibiting the use of the cellular phone or by erasing the internal information. In addition, a plurality of settings can be set as the operation prohibition state, and it is possible to deal with each of cases where there is no possibility of being found, and where there is concern about whether it will be found.
