  FIG. 1 is a diagram illustrating an example of an appearance of a mobile terminal device 100 according to an embodiment of the present invention. 1A is a perspective view from the front direction, and FIG. 1B is a perspective view from the back direction.

  As illustrated in FIG. 1, the mobile terminal device 100 includes a first housing (upper housing) 501 and a second housing (lower housing) 502. These two casings 501 and 502 can be opened and closed with each other by being foldably connected via a hinge portion 503.

  A display portion 518 (107 in FIG. 2) and a speaker 504 (105 in FIG. 2) are arranged on the surface 501A of the first housing 501 that faces the second housing 502 in the folded state (closed state). . A key group 517 and a microphone 505 (106 in FIG. 2) are arranged on the surface 502A of the second housing 502 facing the first housing 501 in the closed state.

A non-contact IC chip unit 506 (109 in FIG. 2) is built in the second housing 502. The non-contact IC chip unit 506 includes an IC chip 510 on which a communication circuit or the like is formed, and an antenna 520 (112 in FIG. 3) formed by wiring on a circuit board.
A telescopic antenna 507 (AT1 in FIG. 2) for performing wireless communication with a base station of a mobile phone network is disposed on the hinge portion 503 of the second housing 502.
A side key 519 for an IC chip, which will be described later, is disposed on the side surface in the longitudinal direction of the second housing 502.

FIG. 2 is a block diagram illustrating a configuration example of the mobile terminal device 100 according to the embodiment of the present invention.
2 includes a wireless communication unit 101, a key input unit 103, an audio processing unit 104, a speaker 105, a microphone 106, a display unit 107, a storage unit 108, and a non-contact IC chip. Unit 109 and control unit 120.

  The wireless communication unit 101 performs processing related to wireless communication with a base station of a mobile phone network. For example, the transmission data output from the control unit 120 (terminal control unit) is subjected to a predetermined modulation process to be converted into a radio signal and transmitted from the antenna AT1. In addition, a predetermined demodulation process is performed on the radio signal received by the antenna AT 1 to reproduce the received data and output it to the control unit 120.

The key input unit 103 includes, for example, a power key, a call key, a numeric key, a character key, a direction key, a determination key, and keys to which various functions are assigned, and when these keys are operated by the user. Then, a signal corresponding to the operation content is generated and input to the control unit 120 as a user instruction.
A key group 517 and side keys 519 in FIG. 1 are included in the key input unit 103.

  The audio processing unit 104 processes an audio signal output from the speaker 105 and an audio signal input from the microphone 106. That is, the audio signal input from the microphone 106 is subjected to signal processing such as amplification, analog-digital conversion, encoding, and the like, converted into digital audio data, and output to the control unit 120. Further, the audio data supplied from the control unit 120 is subjected to signal processing such as decoding, digital-analog conversion, amplification, and the like, converted into an analog audio signal, and output to the speaker 105.

  The display unit 107 is configured using a display device such as a liquid crystal display panel or an organic EL panel, for example, and displays an image corresponding to a video signal supplied from the control unit 120. For example, various information and images such as the telephone number of the callee at the time of outgoing call, the telephone number of the other party at the time of incoming call, the contents of received mail and outgoing mail, date, time, remaining battery level, standby screen, etc. are displayed.

  The storage unit 108 stores various data used for processing in the control unit 120. For example, in the processing of the computer program provided in the control unit 120, the address book for managing personal information such as telephone numbers and e-mail addresses, audio files for playing ringtones and alarm sounds, various setting data, and program processing Holds temporary data that is used.

  The storage unit 108 is configured by, for example, a non-volatile storage device (non-volatile semiconductor memory, hard disk device, optical disk device, etc.), a randomly accessible storage device (eg, SRAM, DRAM), or the like.

  The non-contact IC chip unit 109 performs non-contact communication with an external reader / writer device 600 by electromagnetic coupling. For example, when the non-contact IC chip unit 109 receives an AM modulation signal emitted as an electromagnetic wave from the external reader / writer device 600, the non-contact IC chip unit 109 returns a response to the reader / writer device 600 by a method such as load modulation. Information is exchanged with the writer device 600.

FIG. 3 is a diagram illustrating an example of the configuration of the non-contact IC chip unit 109.
The non-contact IC chip unit 109 illustrated in FIG. 3 includes an antenna 112, a transmission / reception unit 113, an encryption processing unit 114, a storage unit 115, and an IC chip control unit 116.

  The transmitter / receiver 113 demodulates the baseband signal from the signal received by the antenna 112, reproduces the clock signal based on the carrier component of the received signal, decodes the baseband signal in synchronization with the clock signal, and receives the received signal. Get the data. Further, the transmission data supplied from the IC chip control unit 116 is encoded to generate a transmission signal, and the antenna 112 is driven according to the transmission signal to transmit information to the reader / writer device 600.

  The encryption processing unit 114 performs processing related to encryption and decryption of information exchanged with the reader / writer device 600.

The storage unit 115 stores an encryption key necessary for starting communication with the reader / writer device 600 and various confidential information.
The storage unit 115 also stores electronic money information and the like. Specifically, it is money amount information, and the amount is charged by communication with the reader / writer device 600 or communication connected to an electronic money management server (not shown) using the wireless communication unit 101.

The IC chip control unit 116 (wireless communication control unit) communicates with the reader / writer device 600 based on a predetermined communication protocol, and performs processing for exchanging information. For example, the reader / writer device 600 is connected to an authentication device (not shown), and transmits a random number encrypted with a predetermined encryption key in the authentication device to the non-contact IC chip unit 109. The IC chip control unit 116 uses the encryption key stored in the storage unit 115 to decrypt the encrypted random number using the encryption processing unit 114 and returns it to the reader / writer device 600. The authentication device compares the random number returned to the reader / writer device 600 with the original random number to determine whether or not the non-contact IC chip unit 109 has a properly registered encryption key.
Further, when purchasing a product or the like, communication with the reader / writer device 600 is performed, and the IC chip control unit 116 performs processing for subtracting the amount corresponding to the purchased product from the storage balance of the storage unit 115.

  The antenna 112 functions as a coil and is excited and electromagnetically coupled when receiving electromagnetic waves from the reader / writer device 600. A transmission signal generated by fluctuations in electromagnetic wave intensity from the reader / writer device 600 is received by the antenna 112, and the reception signal is extracted from fluctuations in the induced electromotive force on the antenna 112 side by the transmission / reception unit 113 and the IC chip control unit 116. . In addition, the transmission / reception unit 113, the encryption processing unit 114, the storage unit 115, and the IC chip control unit 116 may be driven by a power source on the mobile phone 100 side or by an induced electromotive force from the antenna 112.

The control unit 120 comprehensively controls the overall operation of the mobile terminal device 100. That is, various processes of the mobile terminal device 100 (voice calls performed via a circuit switching network, creation and transmission / reception of e-mails, browsing of Internet websites, etc.) are appropriately performed according to the operation of the key input unit 103. The operation of each unit described above (transmission / reception of signals in the wireless communication unit 101, input / output of audio in the audio processing unit 104, display of images on the display unit 107, etc.) is controlled.
For example, the control unit 120 includes a computer that executes processing based on a program (operating system, application, etc.) stored in the storage unit 108, and executes the above-described processing according to a procedure instructed in this program.

The control unit 120 controls prohibition and cancellation of communication by the non-contact IC chip unit 109. That is, when the side key 519 as the first operation means is not pressed, the control unit 120 prohibits communication by the non-contact IC chip unit 109.
Specifically, when restricting wireless communication of a non-contact IC (RFID), the control unit 120 blocks power supply to the non-contact IC control unit. That is, the wireless communication is restricted by cutting off the power source on the mobile phone 100 side or the supply path of the induced electromotive force from the antenna 112 side. Further, it is also possible to simply send a control signal that instructs the non-contact IC control unit not to perform wireless communication.
As described above, by prohibiting the communication of the non-contact IC chip unit 109 unless the user intentionally operates the key, the non-contact IC chip unit 109 and the reader / writer device 600 are automatically operated without the user's intention. To prevent communication.

  The “prohibition of communication” includes not only the case where communication of all information in the non-contact IC chip unit 109 is prohibited, but also the case where communication is restricted to specific information. For example, communication is prohibited for specific confidential information stored in the storage unit 115, but transmission / reception with the reader / writer device 600 is permitted for other information.

  Further, the control unit 120 has a clock function, and prohibits communication by the non-contact IC chip unit 109 even when the side key 519 is pressed during a preset time period. For example, when the non-contact IC chip unit 109 is used as a commuter ticket, communication of the non-contact IC chip unit 109 is prohibited except for a time zone during which the user commutes on a daily basis. This prevents others who do not know the prohibited time zone from using the non-contact IC chip unit 109 easily.

Further, the control unit 120 counts the number of times of communication of the non-contact IC chip unit 109 within a predetermined time, and when the number reaches a preset upper limit value, the non-contact even if the side key 519 is pressed. Communication by the IC chip unit 109 is prohibited. This prevents the non-contact IC chip unit 109 from being illegally used indefinitely in a state not intended by the user.
For example, a non-contact communication for confirming a commuter pass contract for passing through a commuter pass ticket gate and a non-contact communication for an addition / subtraction of an electronic money function that can be used by charging the storage unit 115 are separated. If the non-contact communication is determined only when communication is performed by the control unit 120 and the electronic money function is communicated, the convenience as a commuter pass is not impaired at all.

Further, the control unit 120 prohibits communication by the non-contact IC chip unit 109 even when the side key 519 is pressed when the number of communication of the non-contact IC chip unit 109 reaches a preset upper limit value for each time zone. To do. By setting limits on the time zone and the number of times of communication, unauthorized use of the non-contact IC chip unit 109 by others is made more difficult.
In other words, it may be set that it can be used twice in the morning work hours and only twice in the evening work time, and the non-contact communication is allowed only within the set time and within the set number of times. You may make the control part 120 perform.

However, in the case where the time zone and the number of communication times are set as described above, it is more convenient that the user can freely release the limit.
Next, when non-contact communication is prohibited, the control unit 120 sets a predetermined password by using another key (second operation unit) of the key input unit 103 while the side key 519 is pressed. If input, the prohibition of communication of the non-contact IC chip unit 109 is released.
In this case, if a number different from the predetermined password is input, or if the predetermined password is not input within a certain time, the control unit 120 continues prohibition after that and does not contact As a condition for canceling the prohibition of communication by the IC chip unit 109, in addition to pressing the side key 519, the input of a personal identification number may always be requested. As a result, if a person who attempts unauthorized use of the non-contact IC chip unit 109 inputs an incorrect password, the communication prohibition of the non-contact IC chip unit 109 cannot be lifted simply by pressing the side key 519. Will improve.

  Needless to say, the conditions for releasing the restriction such as the time zone and the number of times and the restriction target as described above are stored and managed in the storage unit 108 when set by the key human power unit 103 or the like.

  On the contrary, the control unit 120 does not input a predetermined password by another key (second operation unit) of the key input unit 103 even when the side key 519 (first operation unit) is being pressed. May always prohibit communication by the non-contact IC chip unit 109. As a result, in order to cancel the prohibition of communication by the non-contact IC chip unit 109, it is always required to input a personal identification number in addition to pressing the side key 519, so that the security is improved.

  Further, the control unit 120 controls notification of the notification-related unit such as the screen of the display unit 107 so as not to notice that the input of the above-described password is requested. That is, the same key of the key input unit 103 is operated in the same manner in a state where the communication prohibition of the non-contact IC chip unit 109 can be canceled by inputting the personal identification number and a state where the prohibition cannot be canceled even if the personal identification number is input. In this case, the display state of the display unit 107 and the output sound of the speaker 105 (that is, the notification of the notification unit) are controlled to be the same so that the two states cannot be discriminated. In other words, for example, even if reception of a password is started by pressing the side key 519 or the like, the notification unit is controlled so that this cannot be determined from the notification state of the notification unit. Accordingly, since it is impossible to grasp from the notification state of the notification unit that the communication prohibition of the non-contact IC chip unit 109 can be canceled by inputting the personal identification number, security resistance against an unauthorized user attack is improved.

The control unit 120 may arbitrarily set the above-described communication prohibited time zone, the upper limit value of the number of communication times, a password, and the like according to the setting information input from the key input unit 103. Further, according to the setting information, a key (IC chip key) as a first operation means to be pressed to use the non-contact IC chip unit 109 may be assigned to a key other than the side key 519. . This prevents others who do not know the assignment of the IC chip key from using the non-contact IC chip unit 109 easily.
In addition, the control unit 120 may change the allocation of the IC chip key for each predetermined time period in accordance with the setting information input from the key input unit 103. As a result, the key for the IC chip can be changed according to the time zone, such as a side key in the morning and a clear key in the evening, so that it becomes more difficult for another person to use the non-contact IC chip unit 109.

  The key assigned as the first operation means for the IC chip has the same apparent process before and after the assignment. That is, if the key assigned as the first operation means is the address book call key, the control unit 120 controls to display that the address book is called when operated not only before the assignment but also after the assignment. This makes it very difficult to grasp a clue to cancel the prohibited state of the IC card function, making unauthorized use of the non-contact IC card unit 109 even more difficult.

  As described above, in the state where communication by the non-contact IC is prohibited, since the normal operation is performed only by operating the first operation means, an operation for releasing is entered even if the notification is confirmed. I don't know if it is. Further, when the password is input by the numeric keypad as the second operation means after the first operation means is operated in this way, the function originally assigned to the first operation means is first processed. Thereafter, the operation corresponding to the input of the ten key that is subsequently pressed is visually executed. That is, the key assigned as the first operation means for the IC chip in the state where the first operation means is operated has the same apparent process before and after the assignment. For example, if the key assigned as the first operation means is an address book call key, the control unit controls to display that the address book is called when operated not only before the assignment but also after the assignment. Thereby, it is configured so that it is not known at a glance whether or not the release operation is performed. When the correct password is input within a certain period of time, the control unit 120, when canceling the prohibition of communication by the non-contact IC chip unit 109, the screen display of the display unit 107, the sound of the speaker 105, and a vibrator (not shown) Etc.), the user is notified of the cancellation of the communication prohibition.

  As an example of keys assigned as the first operation means, a side key, a clear key, and an address book call key are shown, but other keys may be used. However, when the control unit 120 performs a process of executing the function originally assigned to the operated first operating unit in accordance with the operation, the first operating unit includes a power key (the power is turned off). ), A call key (because a call is subsequently made for a number input by the numeric keypad), and a camera key (because the camera is activated) are not preferable.

  Here, the operation of the mobile terminal device according to the present embodiment having the above-described configuration will be described with reference to the flowchart shown in FIG.

  When communication with the non-contact IC chip unit 109 is prohibited (step ST105), the control unit 120 monitors whether or not an IC chip key (for example, the side key 519) is pressed (step ST110).

  When the IC chip key is pressed, control unit 120 determines whether or not it is currently locked (step ST145). Here, the locked state indicates a state in which the communication prohibition of the non-contact IC chip unit 109 cannot be removed unless a password is entered in addition to pressing the IC chip key.

  In addition to the determination of the lock state, the control unit 120 determines whether or not the current time is in a predetermined prohibition time zone for prohibiting communication of the non-contact IC chip unit 109 (step ST120), and the prohibition time zone It is also determined whether the number of communications of the non-contact IC chip unit 109 performed within (or within a predetermined time) exceeds the limit number (step ST125).

  As a result of the above determination, when the lock state is not set, the current time is not the prohibited time zone, and the number of communication times does not exceed the limit, the control unit 120 performs a predetermined notification that the communication prohibition of the non-contact IC chip unit 109 is released. The operation is notified (step ST150), and the IC chip function is validated (step ST155). For example, the user is notified that the non-contact IC chip unit 109 can be used by the screen display of the display unit 107, the sound of the speaker 105, the light emission of the light emitting unit (not shown), the vibration of the vibration unit (not shown), etc. To do.

  On the other hand, control unit 120 starts input of a personal identification number in the locked state, when the current time is a prohibited time zone, or when the number of communications exceeds the limit (step ST130). However, at this time, information indicating that an operation for canceling the prohibition of non-contact communication is being performed is not displayed on the display unit 107 at all.

When the input of the password is started, the control unit 120 monitors the operation of the key input unit 103 (step ST135).
When a personal identification number is input within a predetermined time from the input start time of step ST130 (step ST135), and the personal identification number matches that previously registered in the storage unit 108 (step ST140), the control unit 120 performs communication. The cancellation of the prohibition is notified (step ST150), and the IC chip function is enabled (step ST155).
On the other hand, when a password is not input within a predetermined time from the input start time of step ST130 (step ST135), or when the input password does not match that registered in the storage unit 108 (step ST140). Then, the control unit 120 shifts to the locked state (step ST145) and maintains the communication prohibition of the non-contact IC chip unit 109 (step ST170).

  When the IC chip function is enabled (step ST155), the control unit 120 monitors whether or not the IC chip key is pressed (step ST160). When the IC chip key is no longer pressed (that is, when the user removes his / her finger from the key), control unit 120 performs a predetermined notification operation (step ST165), and again prohibits communication of non-contact IC chip unit 109 ( Step ST170).

  As described above, according to this embodiment, when the IC chip key (for example, the side key 519) is not pressed, communication by the non-contact IC chip unit 109 is prohibited. Accordingly, it is possible to reliably prevent the non-contact IC chip unit 109 and the reader / writer device 600 from automatically communicating with each other in a state not intended by the user. For example, it is possible to effectively prevent an act of accessing data of the non-contact IC chip unit 109 without using the IC card skimmer or the like without the user's knowledge.

  Further, according to the present embodiment, by restricting the use of the IC chip function according to the time zone and the number of communications, it becomes impossible for others to use the non-contact IC chip unit 109, so that security can be improved.

  Furthermore, since the restriction on the time zone and the number of communication can be arbitrarily set according to the setting information, the security level of the IC chip function can be freely set according to the daily behavior of the user. For example, in a time zone in which the IC chip function is frequently used, the prohibition state can be canceled by simply pressing the IC chip key, but in other time zones, the prohibition state cannot be canceled unless a password is entered. In addition, it is possible to make adjustments such as loosening the limit on the number of communications particularly in a high-usage time zone and constricting the limit on the number of communications in a time zone where no use is planned. Thereby, it is possible to improve convenience while ensuring sufficient security against unauthorized use.

  Also, if the password entered for canceling the communication prohibition of the non-contact IC chip unit 109 is wrong or the password is not entered within a predetermined time, the password is entered in addition to pressing the IC chip key. By providing a lock state in which the non-contact IC chip unit 109 cannot be used unless it is performed, sufficient security can be ensured even if it is lost or stolen.

  Moreover, according to the present embodiment, the person who tries to illegally use the IC chip function by controlling the screen of the display unit 107 so as not to notice that the input of the personal identification number has been requested, In addition to not knowing the password, it is impossible to grasp that the input of the password is required, so that the security can be further improved.

  As mentioned above, although an example of embodiment of this invention was demonstrated, this invention is not limited only to said form.

  In the embodiment described above, a key (push button) is cited as an example of an operation unit for canceling communication prohibition of the non-contact IC chip unit 109, but the present invention is not limited to this. That is, the operation means is arbitrary, and may be a dial, a slide switch, a pressure sensitive switch, a touch panel, or the like.

  In the above-described embodiment, the personal identification number is given as an example of information input to cancel the communication prohibition of the non-contact IC chip unit 109, but the present invention is not limited to this. For example, the communication prohibition of the non-contact IC chip unit 109 may be canceled based on biological information input using a device that reads a fingerprint or a vein pattern.
