The owner operates the telephone 500 to send the authentication data 506 to the security controller 501 (operation U2). In response, the security controller 501 returns a request confirmation 507 (operation S2).
[0009]
When the owner operates the telephone 500 and sends a protection request 508 to the security controller 501 (operation U3), the security controller 501 transmits a mobile terminal search request 510 to the PHS system DB 502 (operation S3). The PHS system DB 502 searches for the presence / absence of location registration, and sends the search result to the security controller 501 as a mobile terminal search response 511 (operation N1).
[0010]
When the position of the target portable terminal 503 is registered, the security controller 501 transmits an information protection instruction 512 to the portable terminal 503 (operation S4). The mobile terminal 503 that has received the information protection instruction 512 executes the protection program and sends a protection completion report / data accompanied by protection data to the security controller 501 (operation P1). When the lost important information in the portable terminal 503 is collected and invalidated in the security controller 501, the security controller 501 sends an end notification 509 to the telephone 500 to notify the owner (operation S5). .
[0011]
FIG. 6 is a block diagram showing a configuration of a portable electronic device having a personal authentication function based on biometric risk information proposed in Patent Document 2. Patent Literature 2 discloses a method of protecting confidential information by using personal authentication based on biometric information that cannot be stolen or imitated.
[0012]
In FIG. 6, a biometrics information input unit 614 measures and inputs biometrics information of a person to be authenticated. The biometric feature information extraction unit 615 extracts collation biometric feature information from the biometric information measured by the biometric information input unit 614. The reference biometric feature information storage unit 616 stores reference biometric feature information about the owner of the device in advance.
[0013]
The biometric feature information matching unit 617 compares the matching biometric feature information extracted by the biometric feature information extracting unit 615 with the reference biometric feature information stored in the reference biometric feature information storage unit 616. Compare and collate.
[0014]
When the biometrics characteristic information for verification is compared with the biometrics characteristic information for reference and the biometrics characteristic information for reference is recognized as the result of the verification, the display control unit 620 stores the secret information in a secret code. The secret information is read from the unit 619, and the secret information is controlled to be displayed on the information display unit 618.

[0032]
The input device 103 acquires the biometric information of the user who is the recognition target person, and passes the acquired biometric information to the personal authentication unit 102. Here, the biometric information is, for example, a fingerprint, palm print, finger type, voice, retina, iris, or the like.
[0033]
In the owner determination memory 104, the biological information of the owner is stored in advance as reference biological information.
[0034]
The personal authentication unit 102 compares the biometric information of the user who is the recognition target person acquired by the input device 103 with the biometric information of the owner stored in the owner determination memory 104 in advance, and The determination result of the owner / non-owner is passed to the CPU 101.
[0035]

[0039]
Next, the operation of the mobile phone terminal device configured as described above will be described. When the user turns on the main power supply 106, the CPU 101 first activates the personal authentication unit 102. When the user inputs biometric information into the mobile phone terminal device using the input device 103, the personal authentication unit 102 compares the biometric information of the input user with the biometric information of the owner in the owner determination memory 104. The match / mismatch is compared and collated, and the owner / non-owner determination result is passed to the CPU 101.
[0040]
If the determination result of the personal authentication is the owner, the CPU 101 performs control to shift the mobile phone terminal device to a state in which the normal function can be used, and releases the personal authentication mode. If so, the main power supply 106 is turned off.
[0041]
In addition, the CPU 101 monitors the use state in the normal function usable state, and controls the save / restore unit 105 when the unused state continues for a certain period of time to control the program counter, the application being executed, and the operation memory. Evacuate the area. At the same time, the CPU 101 activates the personal authentication unit 102 and enters a standby state.
[0042]
Since the personal authentication mode is maintained even after the non-use processing is performed as described above, when the user uses the mobile phone terminal again, the same personal authentication as described above is performed, and at the same time, the CPU 101 is activated. Changed to state.
[0043]
When the determination result of the personal authentication is the owner, the CPU 101 controls the saving / restoring unit 105 to restore the program counter, the application being executed, and the operation memory area, and return to the normal function usable state. Change state. This cancels the personal authentication mode. However, the CPU 101 does not cancel the personal authentication mode if the result of the personal authentication is a non-owner.

[0047]
(Embodiment 2)
FIG. 2 is a block diagram showing a configuration of the mobile phone terminal device according to Embodiment 2 of the present invention. In FIG. 2, the same reference numerals are given to components that are the same as or equivalent to the configuration shown in FIG. Here, a description will be given focusing on a portion relating to the second embodiment.
[0048]
In the mobile phone terminal device 200 according to the second embodiment shown in FIG. 2, in the configuration shown in FIG. 1, a personal authentication activation unit 201 that activates the personal authentication unit 102 and an owner / non-owner A control unit 202 that receives the determination result of the user and an AND circuit 203 that uses the output of the control unit 202 as one input.
[0049]
The personal authentication activation unit 201 is an interface with the user, and activates the personal authentication unit 102 in response to the operation of the user. The user's actions include, for example, the act of removing the lid of the camera lens when the input device 103 is a camera, the act of operating the keys of the mobile phone terminal device, and the case where the mobile phone terminal device is foldable And flip opening.
[0050]
The control unit 202 sets the output to a high level when the result of determination by the personal authentication unit 102 is the owner, and sets the output to a low level when the result is a non-owner.
[0051]
Further, a main power supply 204 is provided in place of the main power supply 106, and an auxiliary power supply 205 is added. The main power supply 204 is, for example, a battery pack, and supplies an nLVA signal indicating a mounted state to the other input of the AND circuit 203. The nLVA signal is a signal that becomes high when worn and becomes low when not worn.
[0052]
The auxiliary power supply device 205 supplies power to the personal authentication unit 102, the input device 103, the owner determination memory 104, the personal authentication start unit 201, and the control unit 202.
[0053]
When the output of the AND circuit 203 is at a high level indicating reset release, the main power supply device 204 performs an ON operation, and supplies power to each unit not using the auxiliary power supply device 205 such as the CPU 101 and the save / restore unit 105 as a power supply.

When the user inputs biometric information into the mobile phone terminal device using the input device 103, the personal authentication unit 102 compares the biometric information of the input user with the biometric information of the owner in the owner determination memory 104. The match / mismatch is compared and the owner / non-owner determination result is passed to the control unit 202.
[0056]
When the determination result from the personal authentication unit 102 indicates that the user is not the owner, the control unit 202 sets the output to a low level, so that the output of the AND circuit 203 is output from the nLVA signal from the main power supply device 204. Irrespective of the level of, the level is low. As a result, the main power supply device 204 does not receive the reset release signal from the AND circuit 203, and thus does not perform the ON operation.
[0057]
On the other hand, when the determination result from the personal authentication unit 102 indicates that the user is the owner, the control unit 202 sets the output to a high level. When the main power supply 204 is mounted, the nLVA signal is at a high level. As a result, the output of the AND circuit 203 becomes high level, and the main power supply device 204 receives the reset release signal from the AND circuit 203 and turns on.
[0058]
When power is supplied, the CPU 101 performs control to shift the mobile phone terminal device to a state where a normal function can be used. Then, the CPU 101 monitors the use state in the normal function usable state.
[0059]
If the CPU 101 has not been used for a certain period of time, the CPU 101 controls the save / restore unit 105 to save the program counter, the application being executed, and the operation memory area. At the same time, the CPU 101 activates the personal authentication unit 102 and enters a standby state.
[0060]
Since the personal authentication mode is maintained even after the non-use processing is performed as described above, when the user uses the mobile phone terminal device again, the CPU 101 determines whether the owner / user input from the personal authentication unit 102 is used. If the determination result of the non-owner is the owner, the evacuation / restoration unit 105 is controlled to restore the program counter, the application being executed, and the operation memory area, and return to the normal function usable state. To change. This cancels the personal authentication mode. However, the CPU 101 does not cancel the personal authentication mode if the result of the personal authentication is a non-owner.
[0061]
At this time, even when the personal authentication unit 102 is activated, the owner of the mobile phone terminal device is preset to receive various information services such as incoming calls and e-mails, news and weather forecasts. It is possible to do.
[0062]
As described above, according to the second embodiment, personal information can be protected when a terminal is lost or stolen without using a wireless network. Information can be protected.
[0063]
In addition, even if the personal authentication has been performed, if the personal information has not been used for a certain period of time, the personal authentication is performed again. Therefore, even if the personal information is lost or stolen when browsing the personal information, the personal information can be protected.
[0064]
In addition, since the power supply to the personal authentication unit is performed by the auxiliary power supply and the main power supply is not consumed by the authentication operation of the personal authentication unit, the mobile phone terminal can be used for a long time.
