Reference numeral 25 denotes an authentication result transmitting unit that transmits power to each of the lock release devices 20;

Next, the operation will be described with reference to FIG. FIG. 2 is a flowchart showing the operation of the automatic dial lock system for a mobile phone according to Embodiment 1 of the present invention.

First, a specific (regular) user or service provider of the mobile phone 10 stores predetermined ID information set in advance in the code storage circuit 16 of the mobile phone 10 and the ID information of the unlocking device 20. In the circuit 21,
It is input and stored via a ROM writer (not shown) or the like.
The input of the ID information to the code storage circuit 16 of the mobile phone 10 may be performed via the input device 14. When the power of the mobile phone 10 is turned on, the mobile phone 1
0 is in the locked state.

When the power of the mobile phone 10 is turned on (step ST1), the authentication device 17 of the mobile phone 10 is activated.
Generates a random number and supplies it to the control unit 11. Control unit 11
Stores this random number in the code storage circuit 16 as an unlock code (step ST2). Code storage circuit 1
When the lock release code is stored in step 6, the authentication device 17 reads out the ID information and the lock release code stored when the power is turned on from the code storage circuit 16 and performs an authentication operation (arbitrary arithmetic operation or the like) (step). ST3), and supplies the result of the authentication calculation to the control unit 11. Upon receiving the result of the authentication operation, the control unit 11 sends the result of the authentication operation (first
Is stored in the code storage circuit 16.

Next, in order for the user of the mobile phone to perform operations such as calling or accessing personal information such as a memory dial, data is input by a series of key operations from the keyboard of the input device 14 (operation processing request, etc.). Is performed, the operation content corresponding to the data input by the series of key operations is supplied (notified) to the control unit 11. Control unit 1
1 reads the unlock code from the code storage circuit 16 and supplies it to the unlock code transmitting unit 12 at the timing when the operation content is supplied from the input device 14.
The unlock code transmitting unit 12 puts the unlock code on a weak radio wave and transmits it to the unlock device 20 carried (worn) by the user of the mobile phone (steps ST4 and ST5).

When the unlock code receiving section 22 of the unlock device 20 receives the unlock code transmitted from the mobile phone 10 via weak radio waves, it supplies the unlock code to the authentication device 23. When the unlocking code is supplied (received), the authentication device 23 of the unlocking device 20 reads out the ID information stored in the ID information storage circuit 21 in advance, and reads the ID information and the received unlocking code. Performs the authentication calculation (step ST6), and supplies the result of the authentication calculation to the authentication result transmitting unit 24. In addition, the authentication result transmitting unit 24 transmits the result of the authentication operation (second authentication operation result) supplied from the authentication device 23 to the mobile phone 10. (Step ST7)

The transmission output of the unlock code transmitting section 12 of the mobile phone 10 and the receiving sensitivity of the unlock code receiving section 22 of the unlocking device 20 are determined, for example, by the radio wave in the absence of an obstacle (shield). It is adjusted so that the reach distance is about 1 m. The authentication calculation algorithm used by the authentication device 23 of the lock release device 20 is the same as the authentication calculation algorithm of the authentication device 17 of the mobile phone 10.

Next, the authentication result receiving section 1 of the mobile phone 10
8 receives the result of the authentication calculation (second authentication calculation result) transmitted from the unlocking device 20 by a weak radio wave, and supplies the result to the control unit 11. The control unit 11 controls the code storage circuit 1
6, the result of the authentication operation (first authentication operation result) already stored in the memory is read, and the result of the received authentication operation (second authentication operation result) is read out.
And performs authentication (authentication determination by authentication processing) with the authentication operation result (step ST8).

When the results of the comparison and authentication match, the control unit 11 determines that the key input in step ST4 is a specific user (a mobile phone user who is permitted to use the key).
Is determined to be a key input by the user, the lock is released, the transmission operation and the operation of the memory dial and the like input from the input device 14 are validated in step ST4 (step ST9), and the transmission processing and the like are continued (step ST9). Processing can be continued until a series of key input processing is completed.)

On the other hand, the code storage circuit 1 of the mobile phone 10
6 is different from the ID information stored in the ID information storage circuit 21 of the unlocking device 20, or the authentication algorithm of the authentication device 17 of the mobile phone 10 and the authentication device of the unlocking device 20 are different. If the result of the comparison authentication does not match, for example, when the authentication algorithm in 23 is different (when the mobile phone 10 and the unlocking device 20 are not compatible), the control unit 11 returns to step ST4. The key input is determined to be a key input by a non-specific user (a mobile phone user who is not permitted to use),
Unlocking is not performed, and the operation input in step ST4 is invalidated and discarded (step ST10). For example, the transmission operation or the memory access operation input in step ST4 on the display unit 15 is invalid. Is displayed.

Further, during the execution of the permitted transmission processing (transmission operation, access operation to personal information such as memory dial, etc.), the control unit 11 responds to an operation newly notified (input) from the input device 14. Is treated as a locked state. further,
After the permitted calling process is completed, a new input device 14 is set.
In response to the operation notified from, the control unit 11 transmits the unlocking code to the unlocking device 20 again to perform the authentication process. That is, it is possible to continue the operation for a series of key-input processing requests only for a period until a series of processing is completed with respect to the operation once the dial lock is released.

After transmitting the unlock code to the unlock device 20, if the authentication calculation result is not received from the unlock device 20 after a predetermined time has passed, the control unit 11 It is determined that there is no specific user (user permitted to use) near 10, the input operation is discarded without unlocking, and the display operation unit 15 of the mobile phone 10 is determined. A message is displayed indicating that the input call operation or memory access operation is invalid.

In the above-mentioned invention, in the event that the unlocking device 20 is forgotten or lost, for example, the password is unlocked by inputting a password or the like from the mobile phone 10, and the key is released. It is also possible to adopt a configuration having a function that enables the operation.

Also, for some reason (system failure, etc.)
In the case where the authentication has failed, the mobile phone 10 may be configured to display a message prompting the user to input a password at the time of the authentication failure. When a password is not manually input after a certain period of time, or when an incorrect password is continuously input a predetermined number of times, the mobile phone 10 is automatically activated. It is also possible to adopt a configuration in which the power supply is turned off.

Further, unauthorized access of the mobile phone 10 due to authentication failure at the time of outgoing call / memory dial access, etc.
If the call is made a predetermined number of times in succession, an automatic call is made to one or more emergency contact numbers registered in the mobile phone 10 in advance (for example, the number of a home fixed phone or a family mobile phone). It is also possible to adopt a configuration having a function of notifying that there has been unauthorized access.

In order to reduce power consumption, the unlocking device 20 is configured to receive an unlocking code from the mobile phone 10 so that the main power supply starts up from the power saving standby state. Alternatively, when the mobile phone 10 is used, the power of the unlocking device 20 may be turned on at the same time as the mobile phone 10.

Further, between the mobile phone 10 and the unlocking device 20, each data is exchanged (communicated) by carrying the authentication calculation result and the unlocking code on a communication medium such as a weak radio wave. Therefore, the strength of a communication medium (signal) such as a weak radio wave between the mobile phone 10 and the unlocking device 20 may be automatically controlled (more weakly) according to the communication status of each data. .

As described above, according to the first embodiment, in the conventional method, the unlock code is transmitted from the unlock device 40 to the mobile phone 30 at a constant period. When the user performs an operation (key input) such as calling or accessing personal information such as a memory dial, the authentication calculation result is transmitted from the unlocking device 20 to the mobile phone 10.
The effect of remarkably suppressing the power consumption of the lock release device 20 can be obtained.

Further, in the conventional method, once locked, there is a problem that the lock cannot be released until the time corresponding to the lock release code transmission cycle in the lock release device 40 elapses at the longest. According to 1, there is an effect that it is possible to transition from the locked state to the unlocked state in real time.

Further, once unlocked by an operation such as calling and memory dialing, only the operation concerned can be accepted, and the operation inputted thereafter is in a locked state. It is possible to obtain an effect of preventing a malicious use by a third party due to forgetting to set a lock (for example, a function of the mobile phone 10 alone that invalidates a key input at all) or misplacement.

Further, in the authentication processing, an unlock code is generated not by a predetermined numerical value (code) but by a random number, and the mobile phone 10 and the unlock device 20 respectively perform an authentication calculation from the unlock code and the ID information. By doing so, the result of each authentication operation (first and second
The authentication processing result is obtained, and the authentication processing is performed by this. For example, the result of the authentication calculation (second authentication calculation result) output from the unlocking device 20 is converted into a jig (emulation of the unlocking device). (E.g., a device that rates), it is difficult to generate illegally, and the effect of preventing unauthorized use of the mobile phone 10 by a third party can be obtained.

[0048]

As described above, according to the present invention, a lock release code for authenticating an operator is output from the portable telephone to the lock release device, so that the lock release device outputs the lock. Since the authentication calculation result based on the release code is output to the mobile phone, and based on the authentication calculation result, the mobile phone performs authentication processing of the operator of the mobile phone. The transition from the locked state to the unlocked state is performed in real time, and the power consumption of the unlocking device can be significantly reduced.

According to the present invention, when the power of the mobile phone is turned on, the first authentication calculation result generated inside the mobile phone and the second authentication calculation result generated inside the lock release device are compared. When the first and second authentication calculation results match in the mobile phone, the operator is determined to be a specific user by performing authentication determination. This makes it difficult to produce an unauthorized lock release device, and has the effect of preventing the unauthorized use of the mobile phone by a third party to a high degree.

According to the present invention, when the power of the mobile phone is turned on, the first authentication calculation result and the specified unlock code generated inside the mobile phone and the identification code stored in advance in the mobile phone are stored. Generated by performing a predetermined authentication operation with ID information indicating the user of
The authentication calculation result is obtained by using the unlock code supplied from the mobile phone inside the unlock device and the ID information indicating the specific user stored in the unlock device in advance, to the predetermined authentication. Since it is configured to be generated by performing an operation, there is an effect that it is difficult to generate (imitate) the first or second authentication calculation result illegally.

According to the present invention, the authentication process is performed every time a series of operations (key input, etc.) in response to the operation processing request to the mobile phone is performed. , Etc.), the use of a mobile phone by anyone other than a specific user (authorized owner, etc.) due to missetting or misplacement of the key input, etc., that the mobile phone alone has become impossible. effective.

According to the present invention, when the power of the mobile phone is turned on, the lock release code generated inside the mobile phone is used as a random number, so that the first or second authentication calculation result is incorrectly generated (imitation). Has the effect of making it more difficult to do

According to the present invention, when the authentication process is performed continuously for a predetermined number of times and no authentication is determined, the emergency contact information of one or more emergency contacts registered in the mobile phone in advance is obtained. Since it was configured to automatically call the number and notify that the mobile phone was abused,
Since the specific user (authorized user) of the mobile phone is notified that the mobile phone is being used illegally, the function (service) of the mobile phone is determined by the specific user. ) Can be promptly executed.

According to the present invention, by receiving the unlock code from the portable telephone, the main power of the unlock device which has been in the power saving standby state is started up. This has the effect of significantly reducing consumption.

According to the present invention, the strength of a signal (a weak radio wave or the like) used for communication between the mobile phone and the unlocking device is minimized according to the communication situation.
The power consumption of each of the mobile phone and the unlocking device in communication between the mobile phone and the unlocking device can be minimized, and this has the effect of minimizing the consumption of batteries and the like.

According to the present invention, the maximum intensity of a signal (a weak radio wave or the like) used for communication between the mobile phone and the unlocking device is configured such that the reach of the signal is about 1 m. Since the consumption of batteries and the like in each of the mobile phone and the unlocking device can be further reduced, and the maximum power consumption in the communication between the mobile phone and the unlocking device can be roughly grasped, it is used in the unlocking device. There is an effect that the life of a battery or the like can be simulated with a certain degree of accuracy.
