This is a flag provided to prevent repeated data erasing when the data erasing bit is received again after erasing the personal information data. The state of the data erased flag is stored in the storage unit 107. When the mobile phone 100 is powered on, after being read from the storage unit 107, the data erased flag is set based on the read data.

When the data erased flag is "OFF" (SA6: NO), the CPU 110 controls the storage unit 107 to determine that the personal information stored is not yet erased. Erases information data. The control program stores the personal information data in the storage unit 107.
It has a data table of address information (hereinafter, referred to as address information) indicating in which position of the non-volatile memory. When erasing the personal information data, the personal information data is erased based on this address information table. After erasing the personal information data, the CPU 110 sets the data erased flag to "ON" and stores the state in the storage unit 107 (SA7). In step SA6, "YE
If it is determined to be "S", the processing is terminated because the personal information data has already been erased. When the setting state of the data erase bit is “OFF” (SA4: NO), the data erased flag is set to “OFF”, the state is stored in the storage unit 107, and the process ends.

[1-2. Operation of First Embodiment] Next, the operation of the first embodiment of the present invention will be described. In the operation of the first embodiment of the present invention described below, the customer information management storage device 250 has already been powered on and the CPU 2
It is assumed that the initialization program is read from the ROM 256 by 58 and the initialization process is completed. afterwards,
It is assumed that the control CPU 258 has read the control program from the ROM 256 and is already executing it.

[1-2-1. Operation when Lock Bit is ON] The operation when the lock bit stored in the customer information management storage device 250 is set to “ON” will be described with reference to FIG. Here, the mobile phone 100
The legitimate owner loses the mobile phone 100, and the mobile phone 100 is operated by a person other than the legitimate owner.

In addition, the mobile phone network 200 indicates that the legitimate owner of the mobile phone 100 has lost the mobile phone 100.
The operator who operates the mobile telephone network 200 responds to the contact with the operator who operates the customer information management storage device 25.
It is assumed that the lock bit stored in the storage unit 255 is set to “ON” by operating 0. Further, here, it is assumed that only the lock bit is set to “on” and the data erasing bit is set to “off”.

First, when the power key of the operation section 104 of the mobile phone 100 is operated by the user of the mobile phone 100 to turn on the power, the mobile phone 100 is initialized by the CPU 110 and then read from the ROM 108 by the CPU 110. The control program is read and executed (step S
100).

In the mobile phone 100, when the control program is executed, the communication unit 102 receives, via the antenna 103, the notification information that periodically transmits the position information from the wireless base station 210 (step S10).
1). The received notification information is sent from the communication unit 102 to the CPU.
It is output to 110.

In the CPU 110 to which the notification information is input,
In order to use the service provided by the mobile telephone network 200, a location registration request for registering its location is generated.
This location registration request includes the terminal ID read from the ROM 108. The position registration request is sent to the CPU 110.
The communication unit 102 is controlled by the antenna 103, and is transmitted to the radio base station 210 that is transmitting the above-described notification information via the antenna 103. When the radio base station 210 receives the broadcast information, the base station controller 220 transmits the information. It is transmitted to the exchange 230 (step S102).

The location registration request received by the exchange 230 is further added with area information indicating the communication area handled by the exchange 230 and transmitted to the customer information management storage device 250 (step S10).
3).

The position registration request including the terminal ID and area information is sent to the communication unit 25 of the customer information management storage device 250.
2 is received by the CPU 258 from the communication unit 252.
Is output to. CPU 258 to which the position registration request is input
Then, a user data write request for writing the user data stored in the storage unit 255 to the subscriber information storage unit 231 of the exchange 230 is generated. This user data write request is sent by the CPU 258 to the communication unit 252.
Is controlled to be transmitted to the exchange 230 (step S104).

Upon receipt of the user data write request, the exchange 230 generates a user data write response in response to the request. This user data write response is transmitted from the exchange 230 and received by the customer information management storage device 250 (step S105).

In the customer information management storage device 250, the communication unit 252 receives the user data write response, and the received response is transmitted from the communication unit 252 to the CPU 258. When this response is input to the CPU 258, C
The storage unit 255 is controlled by the PU 258, and step S
The user data including the lock bit and the data erasing bit designated by the terminal ID received in 103 is read.
After the user data is read, the communication unit 252 is controlled by the CPU 258 and the read user data and the terminal ID are transmitted to the exchange 230 (step S10).
6).

After the step S106, the customer information management storage device 250 stores the area information, which is the position information for managing the position of the mobile phone 100, in association with the terminal ID (step S107).

In the exchange 230, when the user data and the terminal ID transmitted from the customer information management storage device 250 are received, the received user data is stored in the subscriber information storage unit 231 in association with the terminal ID. (Step S1
08). After the user data is stored in the subscriber information storage unit 231, the exchange 230 generates a temporary ID, which is an identifier for identifying the mobile phone 100 different from the terminal ID, and stores the temporary ID in association with the above-mentioned terminal ID. It Thereafter, the temporary ID is used as an identifier for identifying the mobile phone 100 between the exchange 230 and the mobile phone 100.
The reason why the terminal ID is not used as an identifier for identifying the mobile phone 100 is that communication may be intercepted if wireless communication is performed using a fixed identifier.

When the temporary ID is generated, the generated temporary I
The lock bit and the data erasing bit of the subscriber information stored in D and the subscriber information storage unit 231 are transmitted to the mobile phone 100 (step S109).

In the mobile phone 100, when the communication unit 102 receives the temporary ID, the lock bit and the data erase bit via the antenna 103, the received information is transmitted to the CPU 110. CP whose temporary ID was received
At U110, a temporary ID assignment response is generated as a response to the reception of the temporary ID. This temporary ID assignment response is transmitted via the antenna 103 when the communication unit 102 is controlled by the CPU 110.
The temporary ID assignment response is received by the wireless base station 210 and transmitted to the exchange 230 via the base station controller 220 (step S110).

After transmitting the temporary ID allocation response, the CPU 110 carries out the processing when the lock bit and the data erase bit illustrated in FIG. 5 are received. According to the flowchart illustrated in FIG. 5, the setting states of the received lock bit and data erase bit are determined. In this case, since the setting state of the received lock bit is "on", the CPU 110 sets the dial lock flag to "on". Thereafter, the user operates the operation unit 10
4 is operated and a call instruction is input from the user of the mobile phone 100, the CPU 110 refers to the dial lock flag before the call is started. In this case, since the dial lock flag was set to "on",
The CPU 110 does not connect the call and disables the call.

As described above, in the portable telephone, the dial lock is performed immediately after the power is turned on and it becomes impossible to make a call.

[1-2-2. Operation when Lock Bit is Off] Next, an operation when the setting state of the lock bit is “off” will be described with reference to FIG. 7. Here, it is assumed that the mobile phone 100 returns to the legitimate owner and is operated by the legitimate owner. In addition, the legitimate owner of the mobile phone 100 informs the operator who operates the mobile phone network 200 that the mobile phone 100 is back, and the operator who operates the mobile phone network 200 responds to the notification. It is assumed that the lock bit stored in the storage unit 255 is set to “off” by operating the customer information management storage device 250. In addition, the data erase bit is set to “off”.

In FIG. 7, the operation from step S200 to step S210 is the same as the operation from step S100 to step S110 in FIG. 6, so the description thereof will be omitted.

After transmitting the temporary ID assignment response (step S210), the CPU 110 performs the process when receiving the lock bit and the data erase bit illustrated in FIG. According to the flowchart illustrated in FIG. 5, the setting states of the received lock bit and data erase bit are determined. In this case, since the setting state of the received lock bit is “off”, the CPU 110 sets the dial lock flag to “off”. After that, when the user of the mobile phone 100 operates the operation unit 104 and inputs a call instruction, the CPU 110 refers to the dial lock flag before starting the call. In this case, since the dial lock flag is set to “off”, the CPU 110 enables the call and the mobile phone 10
0 authorized users will be able to make calls.

As described above, when the lock bit is set to "OFF", the dial lock is released and the mobile phone 100 can talk.

[1-2-3. Operation when Data Erase Bit is ON] Next, the operation when the data erase bit stored in the customer information management storage device 250 is set to “ON” will be described with reference to FIG. Here, it is assumed that the legitimate owner of the mobile phone 100 loses the mobile phone 100, and the mobile phone 100 is operated by a person other than the legitimate owner. Further, the legitimate owner of the mobile phone 100 informs the operator who operates the mobile phone network 200 that the mobile phone 100 has been lost, and the operator who operates the mobile phone network 200 responds to the contact with the customer information. It is assumed that the data erase bit stored in the storage unit 255 is set to “ON” by operating the management storage device 250. Further, here, it is assumed that the lock bit is set to “off”.

In FIG. 8, the operation from step S300 to step S310 is the same as the operation from step S100 to step S110 in FIG. 6, and therefore its explanation is omitted.

The CPU 110 of the mobile phone 100 performs the processing when the lock bit and the data erase bit illustrated in FIG. 5 are received after transmitting the temporary ID allocation response (step S310). According to the flowchart illustrated in FIG. 5, the setting states of the received lock bit and data erase bit are determined. In this case, since the received data erase bit is set to “ON”, the CPU 110 causes the storage unit 10 of the mobile phone 100 to operate.
7 is controlled to erase the stored personal information data (step S311). After the personal information data is erased, the data erased flag is set to “ON” and the state is stored in the storage unit 107. By setting the erased flag to "ON", it is determined whether or not the personal information data has already been erased before the personal information data is erased as shown in FIG. When the data erased flag is set to "ON", the data erase operation is not repeated even if the data erase bit is received again.

As described above, when the mobile phone 100 is powered on, the personal information data stored in the storage unit 107 is immediately erased. As a result, it is possible to prevent the private information stored in the mobile phone from being stolen.

[2-1-2. Configuration of Mobile Phone] FIG. 13
FIG. 6 is a block diagram illustrating a hardware configuration of the mobile phone 100 according to the second embodiment. In FIG.
The same parts as those in the hardware configuration of the mobile phone 100 according to the first embodiment are designated by the same reference numerals, and the description thereof will be omitted. The mobile phone 100 according to the second embodiment is the first
The difference from the mobile phone 100 according to the embodiment is that the biometrics unit 111 is provided and the program stored in the ROM 108 is different.

The biometrics section 111 is used to input information about the human body of the user of the mobile phone in order to confirm the legal owner of the mobile phone 100. The biometrics unit 111 is, for example, a CCD (Charge-Cou
pled devices) have semiconductor elements that convert optical information into electrical signals, and information specific to the human body such as the iris (black eye pattern of the eyeball) is input.

The ROM 108 has a terminal ID and a control program different from the control program according to the first embodiment. The mobile phone protection function realized by the control program according to the second embodiment will be described below.

(Mobile Phone Protection Function) FIG. 14 shows the processing when the mobile phone 100 receives the lock bit and the data erase bit stored in the customer information management storage device 250 in the second embodiment of the present invention. It is a flowchart which illustrates a flow.

Upon receiving the lock bit and the data erasing bit, the CPU 110 of the mobile phone 100 first determines the setting state of the lock bit (step SE1), and sets the dial lock flag based on the determination result.
Since the dial lock flag is the same as that described in the first embodiment, its description is omitted. In the mobile phone 100, when the user operates the operation unit 104 to input a call instruction, the dial lock flag is referred to before the call is started to determine whether or not the dial lock is performed. When the dial lock flag is “ON”, the CPU 110 does not establish a call connection for a call and disables the call.

When the setting state of the received lock bit is "ON" (SE1: YES), the dial lock flag is set to "ON" to disable the call (SE).
2). When it is determined to be "NO" in step SE1, the following process is performed without doing anything.

After the processing relating to the lock bit is completed,
The CPU 110 determines the setting state of the data erase bit (SE3). When the setting state of the data erase bit is "ON" (SE3: YES), it is determined whether the data erased flag is "ON" (S).
E4). Since this data erased flag is the same as the data erased flag described in the first embodiment, the description thereof will be omitted.

When the data erased flag is "OFF" (SE4: NO), it is determined that the data relating to the personal information has not been erased yet, and the CPU 110 erases the personal information data and backs up the personal information data. Processing is performed (SE5). The data erasing process and the data backup process will be described later. Step SE4
When it is determined to be “YES” in step S3, the process ends without doing anything.

(Data Erasing and Data Backup Function) FIG. 15 is a flow chart exemplifying the flow of the data erasing process of step SE5 shown in FIG. CP
In order to back up the personal information data to be erased, U110 generates a backup request for requesting the backup of the personal information data, and sends it to the customer information management storage device 250 having the function of backing up the personal information data (step SF1). .

After transmitting the backup request, the CPU 110
Waits for a certain period of time until the backup permission response for permitting the backup transmitted from the customer information management storage device 250 is transmitted (SF2). When the CPU 110 receives the backup permission response (SF2: YE
S), the personal information data to be erased is read from the storage unit 107, and the read personal information data and address information are transmitted to the customer information management storage device 250 (SF3). When the backup permission response is not received (SF2: N
O), and after finishing the processing of step SF3, CP
The U 110 controls the storage unit 107 to erase stored data relating to personal information. After that, the data erased flag is set to “ON” and the state is set in the storage unit 1.
It is stored in 07 (SF4).

(Bit information changing function) FIG. 16 shows that the cellular phone 100 determines the legitimacy of the user of the cellular phone 100 and turns the lock bit and the data erasing bit set to "on" to "off". It is a flow chart which illustrates the flow of processing at the time of setting.

When the user of the mobile phone 100 inputs an instruction to judge the validity of the user of the mobile phone 100 into the operation unit 104, the CPU 110 performs the processing illustrated in FIG. First, the CPU 110 waits until the data of the iris of the user of the mobile phone 100 read by the biometrics unit 111 is input (step SG1: NO). When the iris data of the user is input (SG1: YES), the input iris data is compared with the iris data of the valid user stored in the storage unit 107, and the current user is identified. It is determined whether the user is a legitimate user (SG2). When the input iris data is not the same as the iris data stored in the storage unit 107 (SG2: NO), it is determined that the current user is not a valid user, and the process ends.

If "YES" is determined in step SG2, it is determined whether the setting state of the lock bit is "ON" (SG3). When the lock bit is set to "ON", the dial lock flag is set to "OFF" and the dial lock is released (SG
3). When the setting state of the lock bit is "OFF" (SG3: NO), the lock bit is already "OFF", and therefore the following process is performed without performing the process related to the dial lock flag.

Next, the CPU 110 determines whether or not the setting state of the data erase bit is "ON". If the setting state of the data erase bit is “OFF” (SG
5: NO), the process regarding the bit information is ended without performing the process regarding the data erase bit.

When the setting state of the data erasure bit is "ON" (SG5: YES), the erased personal information data is restored, so that the data is erased from the customer information management storage device 250. A data request for the backed up data is transmitted (SG6).

After transmitting the data request, CPU 110 waits for a certain period of time until personal information data and address information backed up from customer information management storage device 250 are transmitted (SG7).

When the personal information data and the address information are received (SG7: YES), CPU 110 controls storage unit 107 to store the received personal information data in storage unit 107 based on the address information ( SG
8). When the personal information data and the address information are not received for a certain period of time, the following processing is performed without performing the restoration processing of the personal information data (SG7: NO).

After the processing relating to the restoration of the personal information data is completed, CPU 110 sets the data erased flag to “off” and stores the state in storage unit 107. After that, a bit change request for changing the setting states of the lock bit and the data erase bit stored in the customer information management storage device 250 to “OFF” is generated and transmitted to the customer information management storage device 250 ( SG9).
