Description

  The present invention relates to a portable terminal equipped with a non-contact IC card function unit and a method for unlocking the non-contact IC card function unit.

  Electronic commerce using a mobile phone equipped with a non-contact IC card function unit is rapidly spreading. A cellular phone equipped with a non-contact IC card function unit is highly convenient because electronic money shopping can be performed simply by bringing the terminal close to an external reader (reader / writer) without using the communication function of the cellular phone. However, if a mobile phone equipped with a non-contact IC card function unit is left behind, there is a risk that a third party may use electronic money. Furthermore, because of the non-contact type, even when the user has a mobile phone, electronic information and electronic money may be stolen without the user's knowledge. For example, in a crowded train, etc., a third party who puts an external reading device in a bag closes the user's mobile phone with a non-contact IC card function unit, so that the electronic information from the mobile phone with a non-contact IC card function unit There is a risk that electronic money will be stolen.

  Therefore, it is desirable to lock the non-contact IC card function unit in a normal state and release the lock when using the non-contact IC card function unit so that the non-contact IC card function unit can be used. In Patent Document 1, as a technique for locking and unlocking the non-contact IC card function unit, the non-contact IC card function unit is normally locked, and when the input code number matches the registered code number, the lock is performed for a predetermined time. Mobile terminals to be released have been proposed.

  In Patent Document 2, as a method for unlocking a contact type IC card function, a personal identification number input with a keypad is a first key, and a rhythm such as light tapping with a finger detected by a pressure-sensitive element is second. There has been proposed an IC card that is used as a key and unlocks the contact IC card function when the first key and the second key coincide with each other. In the IC card of Patent Document 2, after inserting the IC card into the POS terminal and inputting the personal identification number using the keyboard of the POS terminal, the IC card is once pulled out from the POS terminal, and the IC card is tapped with a finger. The electronic commerce is executed by inserting it again into the POS terminal.

And a control means for releasing the lock of the non-contact IC card function unit when the two match.

  An unlocking method according to the present invention is an unlocking method for a portable terminal equipped with a non-contact IC function unit whose function is locked in a normal state, and a storage step for storing a first vibration pattern; An acceptance step for accepting a request for unlocking the IC card function unit, a detection step for detecting a tapping applied to the portable terminal, and a recognition for recognizing the second vibration pattern from the detected tapping when the request is accepted And a step of comparing the first vibration pattern and the second vibration pattern, and releasing the lock of the non-contact IC card function unit when both match each other.

  In the portable terminal and the unlocking method according to the present invention, the non-contact IC card function unit is locked so as not to function in a normal state. Therefore, even if a mobile terminal is misplaced or a third party intentionally brings an external reading device close to the user's mobile terminal in a crowded train, the electronic information and electronic money of the mobile terminal are illegally used or stolen. Can be prevented.

  In addition, when the user makes an unlock request using the reception unit of the mobile terminal, the second vibration pattern is recognized, and the second vibration pattern is recognized as the first vibration pattern stored in the mobile terminal. When the vibration pattern matches, the non-contact IC card function unit is unlocked.

  Since this portable terminal can be brought close to the external reading device after unlocking the non-contact IC card function part in advance, the usage time of the external reading device can be shortened, and Only one approach is required. Therefore, the convenience of the non-contact IC card function unit is not lowered.

(First embodiment)
FIG. 1 shows the configuration of an electronic information exchange system using a portable terminal according to the first embodiment of the present invention. In FIG. 1, an electronic information transfer system 1 includes a mobile terminal 2 equipped with a non-contact IC card function unit, an external reading device 3, a communication network 4, and a provider server 5. Here, the function of the non-contact IC card function unit of the portable terminal 2 is locked in a normal state.

  When the user performs electronic commerce with the provider server 5 using the non-contact IC card function unit of the mobile terminal 2, first, the mobile terminal 2 is released from the non-contact IC card function unit using the operation unit as an accepting unit. After that, a predetermined push is applied to the portable terminal 2. When a predetermined push is applied to the mobile terminal 2, the non-contact IC card function unit of the mobile terminal 2 is unlocked. After the non-contact IC card function unit is unlocked, the user brings the mobile terminal 2 close to the external reader 3 and performs electronic commerce with the provider server 5 via the communication network 4.

  Next, the portable terminal 2 will be described with reference to FIG. FIG. 2 is a block diagram of the mobile terminal 2. In FIG. 2, the portable terminal 2 includes an operation unit 25, a non-contact IC card unit 26, a vibration detection unit 27, and a control unit 30.

  The operation unit 25 receives a request for unlocking the non-contact IC card unit 26 from the user and notifies the control unit 30 of the request. The non-contact IC card unit 26 transmits / receives electronic information to / from the external reading device 3, and updates the electronic information based on the transmission / reception result. Here, the operation of the non-contact IC card unit 26 is locked in a normal state. The vibration detection unit 27 detects a press applied to the mobile terminal 2, converts it into a voltage, and outputs it.

  The control unit 30 stores the first vibration pattern registered in advance, and recognizes the second vibration pattern from the voltage output from the vibration detection unit 27 when the operation unit 25 is notified of acceptance of the unlocking request. Then, the first vibration pattern is compared with the stored first vibration pattern. And when both correspond, the lock | rock of the non-contact IC card part 26 is cancelled | released.

  Next, a method for recognizing the second vibration pattern from the pressing applied to the portable terminal 2 and a method for comparing the first vibration pattern and the second vibration pattern will be described with reference to FIG.

  When the user presses the portable terminal 2 with a predetermined rhythm with a fingertip or the like, the vibration detection unit 27 outputs a voltage indicating a change as shown in FIG.

  The control unit 30 starts recognizing the vibration pattern when the operation unit 25 is notified of acceptance of the unlock request. Thereafter, the first detected voltage change occurrence (voltage rise) is set as the starting point of the voltage change pattern. Then, the voltage change pattern is recognized from the time change of the voltage value. Furthermore, if the next voltage is not detected after a predetermined time has elapsed since the voltage change pattern was detected, the last detected voltage is used as the end point of the voltage change pattern, and the vibration pattern is recognized. Exit.

  Note that the vibration pattern recognition may be ended by the user explicitly inputting the vibration pattern recognition end using the operation unit 25.

  Then, the control unit 30 binarizes (digitizes) or N-values (standardizes) the recognized voltage change pattern. The voltage change pattern that has been digitized and standardized is defined as a second vibration pattern. 3B and 3C show a state where the recognized voltage change pattern is digitized and standardized.

  When it is only necessary to recognize and output only the added hitting interval as a vibration pattern, a binarized (digitized) vibration pattern may be obtained as shown in FIG. Further, when the strength of pressing is recognized and output as a vibration pattern, an N-value (standardized) vibration pattern may be obtained as shown in FIG.

  Here, the unlocking vibration pattern (first vibration pattern) registered in advance is also stored in a digitalized or standardized state. Then, the determination of whether or not the first vibration pattern and the second vibration pattern are identical takes the difference between the two vibration patterns that have been digitized or standardized, and when the difference is smaller than a predetermined threshold, It is determined that the first vibration pattern matches the second vibration pattern. Note that the comparison between the first vibration pattern and the second vibration pattern gives a temporal allowable value within a range where both can be recognized as being similar.

  As described above, since the operation of the non-contact IC card unit 26 is locked in the normal state, the mobile terminal 2 according to the first embodiment is locked by a third party when the mobile terminal 2 is misplaced or a crowded train or the like. However, even when the external reading device 3 is brought close to the mobile terminal 2, it is possible to prevent the electronic information and electronic money from being illegally used or stolen from the mobile terminal 2.

  In addition, when the user performs a predetermined operation using the operation unit 25 of the mobile terminal 2, the control unit 30 recognizes the hit given by the user as the second vibration pattern and compares it with the first vibration pattern. To do. And when the 1st vibration pattern and the 2nd vibration pattern correspond, the lock | rock of the non-contact IC card part 26 is cancelled | released.

Since the non-contact IC card unit 26 is unlocked in advance and then brought close to the external reading device 3, the usage time of the external reading device 3 can be shortened and the proximity to the external reading device 3 can be performed only once. That's it. Therefore, the convenience of the non-contact IC card function unit is not lowered.

  The non-contact IC card unit 26 includes a non-contact IC chip unit 261 and a non-contact communication unit 262. The non-contact communication unit 262 transmits / receives electronic information read from the non-contact IC chip unit 261 to / from the external reading device 3. Then, the electronic information recorded in the non-contact IC chip unit 261 is rewritten based on the transmitted / received electronic information. Here, the non-contact IC chip unit 261 is locked so that access such as reading and rewriting of electronic information cannot be performed in a normal state. Then, when the user gives a predetermined push to the mobile phone 10, the lock is released only for a certain period.

  The vibration detection unit 27 is driven by a command from the control unit 30, and outputs the voltage output from the vibration sensor 21 to the control unit 30.

  The timer 28 is a general timer, starts timing in response to an instruction from the controller 30, and notifies the controller 30 of "predetermined time" when a predetermined time has elapsed.

  The storage unit 29 includes a ROM (Read Only Memory), a RAM (Random Access Memory), an SD memory (Secure Digital Memory), a flash memory, and the like, and stores various information. In the second embodiment, the storage unit 29 stores a vibration pattern for unlocking the non-contact IC card unit 26. Further, a first predetermined time for unlocking the non-contact IC chip unit 261 (non-contact IC card unit 26) and a second predetermined time for driving the vibration detection unit 27 are stored. The first predetermined time and the second predetermined time will be described later.

  The control unit 30 controls each unit. When the operation unit 25 is notified of acceptance of the unlocking request, the vibration detection unit 27 is driven, and the vibration pattern is recognized from the voltage output from the vibration detection unit 27. Then, the recognized vibration pattern is compared with the vibration pattern for unlocking the non-contact IC card unit 26 stored in the storage unit 29. If the two match, the lock of the non-contact IC card unit 26 is performed. Is released.

  Here, the vibration pattern for unlocking the non-contact IC card unit 26 is registered by the user when the user first uses the non-contact IC card function unit. Further, the user can set a time (first predetermined time) for unlocking the non-contact IC card unit 26. The flow of registration of the vibration pattern for unlocking and registration for the first predetermined time will be described with reference to FIG.

  First, the operation unit 25 detects that the user intends to use the non-contact IC card function unit for the first time or that the user has selected to register / update the vibration pattern using the operation button 15 of the mobile phone 10. Then, the control unit 30 is notified of "vibration pattern registration / update request" (S101). In response to the “vibration pattern registration / update request”, the control unit 30 displays on the LCD 13 (or the LCD 18) a prompt to give the mobile phone 10 a push with the mobile phone 10 closed (S102). Further, the vibration detection unit 27 is driven (S103). The user taps the hit area 20 of the mobile phone 10 according to the display on the LCD 13 (or LCD 18).

  The vibration detection unit 27 outputs the voltage output by the vibration sensor 21 in response to the user's pressing to the control unit 30 (S104). The control unit 30 recognizes the vibration pattern from the voltage output from the vibration detection unit 27 and temporarily registers it in the storage unit 29 as a vibration pattern for temporary registration (S105).

  Next, the control unit 30 displays on the LCD 18 for prompting the user to make a confirmation hit on the mobile phone 10 (step 106). When the user presses the pressing area 20 of the mobile phone 10 again according to the display on the LCD 18, the vibration sensor 21 and the vibration detection unit 27 output a voltage corresponding to the pressing, and the control unit 30 recognizes it as a vibration pattern for confirmation. (Step 107). Furthermore, the control unit 30 compares the vibration pattern for confirmation with the vibration pattern for temporary registration temporarily registered in the storage unit 29 and determines whether or not they match (step 108).

  If the confirmation vibration pattern and the temporary registration vibration pattern match in step 108, a display for instructing the user to open the mobile phone 10 is displayed on the LCD 18. Then, after detecting the open state of the mobile phone 10, a display for confirming whether or not the vibration pattern for temporary registration is registered as the vibration pattern for unlocking the non-contact IC card unit 26 is displayed on the LCD 13 (step 109). . When the user selects “Register”, the temporary registration vibration pattern temporarily registered in the storage unit 29 is registered in the storage unit 29 as a vibration pattern for unlocking the non-contact IC card unit 26. (Step 110).

  On the other hand, if the vibration pattern for confirmation does not match the vibration pattern for temporary registration in step 108, and if the user selects “do not register” in step 109, the mobile phone 10 is displayed on the LCD 18 or LCD 13 to the user. Is displayed to prompt the user to make a new press (step 111).

Next, the control unit 30 displays on the LCD 13 whether or not to set the unlock time (first predetermined time) of the non-contact IC card unit 26 to the user (step 112). If the user selects “SET”, a display prompting the user to input the unlock time is displayed on the LCD 13 (step 113). When the user inputs a numerical value according to the display on the LCD 13, the control unit 30 stores the input numerical value in the storage unit 29 as the unlocking time (first predetermined time) of the non-contact IC card unit 26 (step 114).
On the other hand, if the user selects “not set” in step 111, the numerical value set as the default is registered in the storage unit 29 as the unlock time of the non-contact IC card unit 26 (step 115). In the second embodiment, “30 seconds” is stored in the storage unit 29 as a lock release time (first predetermined time) by default.

  In the second embodiment, when the confirmation vibration pattern matches the temporary registration vibration pattern, the temporary registration vibration pattern temporarily stored in the storage unit 29 is displayed as a non-contact IC card unit. Although it is registered in the storage unit 29 as a vibration pattern for unlocking 26, the present invention is not limited to this. The first recognized vibration pattern can be registered as it is as a vibration pattern for unlocking the non-contact IC card unit 26, or after the user performs the hit three times or more and makes the determination a plurality of times, the optimum pattern is obtained. The vibration pattern can be registered as a vibration pattern for unlocking the non-contact IC card unit 26.

  In addition, when the user selects “not set” in step 111, “30 seconds” is registered as a lock release time by default, but the present invention is not limited to this. Registration of the unlocking time by the user may be required. Furthermore, the default registration time can be set to “20 seconds”, “5 minutes”, or the like.

  Further, if the unlock time of the non-contact IC card function unit is lengthened, there is a risk that the electronic information and electronic money of the mobile phone 10 are illegally used or stolen. Therefore, when the user sets the unlock time, it is desirable to limit the unlock time that can be registered to a few minutes at the longest.

  Next, a flow in which the user performs electronic commerce with the provider server 5 using the mobile phone 10 equipped with the non-contact IC card function unit will be described with reference to FIG.

  In FIG. 7, when the user performs electronic commerce with the provider server 5 using the mobile phone 10 equipped with the non-contact IC card function unit, the user first presses a predetermined operation button 15 of the mobile phone 10. By operating, the unlocking of the non-contact IC card unit 26 is started.

  In the case of a foldable mobile phone, it is desirable to use an operation button provided on the side surface or the outer surface of the case of the mobile phone so that the operation can be performed in a folded state. In the second embodiment, when the unlocking of the non-contact IC card unit 26 is started, the user operates the operation button 15 provided on the side surface of the lower housing 12. Further, the user gives a predetermined hit to the hit area 20 of the mobile phone 10.

  First, the operation unit 25 detects that the user has operated the predetermined operation button 15 and notifies the control unit 30 of a “lock release request” (step 201). Upon receiving the “unlock request”, the control unit 30 drives the vibration detection unit 27 and also drives the time measurement unit 28 to start time measurement of “second predetermined time” (step 202).

  During a period until the second predetermined time elapses (step 203), the vibration detection unit 27 outputs the voltage output by the vibration sensor 21 in response to the user's pressing to the control unit 30 (step 204). Then, the control unit 30 recognizes the vibration pattern from the voltage output from the vibration detection unit 27 (step 205), and compares the recognized vibration pattern with the unlocking vibration pattern stored in the storage unit 29. Then, it is determined whether or not they match (step 206). Here, the recognition from the voltage to the vibration pattern is performed by performing the same process as the process described in the first embodiment. If the recognized vibration pattern does not match the unlocking vibration pattern stored in the storage unit 29 and the “second predetermined time” has elapsed in step 203, the vibration detection unit 27. The output of the voltage from is terminated (step 207).

  On the other hand, when the recognized vibration pattern matches the vibration pattern for unlocking, the control unit 30 releases the lock of the non-contact IC chip unit 261 of the non-contact IC card unit 26 and notifies the timer unit 28 of the “first” The timing of “1 predetermined time” is started (step 208). Further, the control unit 30 controls the display unit 23 to display on the LCD 18 that electronic commerce is possible (step 209).

  After confirming the display that electronic commerce is possible, the user brings the mobile phone 10 equipped with the non-contact IC card function unit close to the interface unit 7 of the external reading device 3. Then, during a period until the first predetermined time elapses (step 210), the non-contact communication unit 262 transmits and receives electronic information to and from the external reader 3 based on the electronic information read from the non-contact IC chip unit 261. By doing so, an electronic commerce transaction is carried out with the provider server 5 (step 211).

  When the “first predetermined time” has elapsed, the control unit 30 locks the non-contact IC chip unit 261 of the non-contact IC card unit 26 again (step 212).

  In step 209, the LCD 18 notifies the user that electronic commerce is possible, but the present invention is not limited to this. It is possible to notify the user that electronic commerce is possible by causing the LED 19 to emit light or outputting sound from the speaker 14.

  In the second embodiment, the punching region 20 is formed on the outer surface of the upper housing 11, but the present invention is not limited to this. The punching area 20 may be formed on the lower housing 12 or the side surface or bottom surface of the mobile phone 10. Furthermore, the range in which the user's tapping can be detected by the vibration sensor 21 is set as the tapping region 20, and a clear region may not be set. Furthermore, the present invention is not limited to the concave shape, and the pressing region 20 may be formed of ceramic or the like in order to reduce the sound generated when the user performs the pressing.

  In the second embodiment, the foldable mobile phone 10 is applied as a mobile terminal, but the present invention is not limited to this. You may apply to mobile phones, such as a straight type and a slide type, and may apply to portable terminals, such as PDA (Personal Digital Assistant), PHS, and a portable game machine.

  As described above, the mobile phone 2 according to the second embodiment is locked so that the non-contact IC chip unit 261 cannot be accessed in a normal state. Accordingly, even if the mobile phone 10 is left behind or a third party intentionally brings the external reading device 3 close to the user's mobile phone 10 in a crowded train, electronic information and electronic money are illegally used from the mobile phone 10. Can be prevented from being stolen or stolen.

  Further, the lock of the non-contact IC chip portion 261 is released when the user applies a predetermined hit to the hit area 20 of the mobile phone 10. By forming the punching area 20 on the outer surface of the upper casing 11 of the mobile phone 10, the user does not need to change the folding mobile phone 10 from the closed state to the open state, and the user can press the folded mobile phone 10 in the folded state. can do. Therefore, the convenience of the non-contact IC card function unit is not impaired by the unlocking action.

  If the “second predetermined time” has elapsed in step 203, the operation button 15 provided on the side surface of the lower housing 12 is erroneously operated by terminating the output of the voltage from the vibration detection unit 27. Thus, the unnecessary voltage output and vibration pattern recognition started can be terminated. Therefore, it is possible to prevent wasteful consumption of electric power.

  Furthermore, since the user can set the unlocking time (first predetermined time), the unlocking of the non-contact IC card function unit can be performed appropriately in accordance with the usage style of the user's mobile phone 10.

  The above-described embodiment has been described by taking as an example the case of executing an application that directly transfers electronic money by the non-contact IC card function unit. However, in order to further improve the convenience of the contactless IC card function part, for applications that do not involve the direct transfer of electronic money, such as automatic ticket gate passing by commuter pass use and entrance / exit management, The lock may be automatically released or the lock may not be applied. For example, when communication is performed with an external reading device without unlocking and an application that does not directly exchange electronic money as described above is identified, a function for automatically unlocking may be added. In addition, the user may be able to set the mobile terminal so that the user is not normally locked for each application.
