Abstract

<P>PROBLEM TO BE SOLVED: To provide a mobile terminal device capable of being set to a suppressed state without burdening its user, and very convenient for the user. <P>SOLUTION: Identification information is prevented from being leaked to or acquired illegally by a third person, since the identification information is not sent out from an IC tag 105 until coincidence of key information with collation information is confirmed by a collating portion 103. Moreover, the user can make the mobile terminal device into the suppressed state without bearing a burden, since the IC tag 105 is automatically made into a disapproval state in which the identification information can not be sent out, if a predetermined condition, a condition that a trade has finished satisfactorily, a condition that a trade has not finished within a predetermined period of time fixed by a timer portion 106 because of some cause, or the like for example is detected afterwards to have been satisfied, even if a coincidence output is output from the collating portion 103, and the IC tag once becomes in a state capable of sending the identification information out from the tag 105. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a portable terminal device provided with an IC tag, a transaction system using the same, and a method for controlling the portable terminal device.

Conventionally, many proposals have been made to efficiently conduct commercial transactions using a portable terminal device equipped with an IC tag. For example, when a customer has a contactless IC tag storing a customer information for identifying the person and a mobile phone and pays the money at the cash register at the store after shopping, the contactless IC tag The customer is identified by communicating with the IC tag, and payment is made within the credit limit according to the customer's designation according to the purchase amount. In this case, if there is no problem with the credit, the checkout machine provided at the store will send a list of purchased products and the total amount to the customer's mobile phone as an email, and the customer will reply with an email indicating approval. If so, the transaction ends. Along with this, the customer reads the content of the non-contact IC again at the exit gate, and in this case, it is confirmed by the record of the settlement machine that the settlement of the corresponding customer has been completed. (For example, refer to Patent Document 1). Moreover, in this patent document 1, it is supposed that the personal authentication means which confirms that the person who performs payment is the principal can be added.
JP 2003-187334 A

  However, in the prior art, including the invention described in Patent Document 1, it is impossible to determine whether the customer information stored in the IC tag is the owner, and the portable terminal device provided with the IC tag. If it is lost or stolen, there is a risk of unauthorized use due to impersonation by others.

  In order to avoid this, it is conceivable to add a personal authentication means as suggested in Patent Document 1. As the personal authentication means, for example, a method of using a password to force the mobile terminal device body to be set in a suppressed state is also conceivable. However, simply adding identity authentication means requires the user to operate the mobile terminal device itself in a restrained state and carry it in anticipation of theft or loss, which is very large for the user. It will be burdensome. Therefore, in practical use, it is difficult for users to expect use in such a suppressed state. Therefore, if a mobile terminal device that is not in a suppressed state is passed to a third party, it may be illegally used as in the past. Also, carrying the mobile terminal device in a state where it cannot be used (that is, in a suppressed state) impairs the convenience for the user.

  The present invention has been made in view of the above points, and uses a portable terminal device that is capable of setting the suppression state of the portable terminal device without burdening the user and that is highly convenient for the user. It is an object of the present invention to provide a transaction system and a method for controlling a portable terminal device.

  In order to solve such a problem, the present invention is a portable terminal device that transmits an identification signal for identifying a user from an IC tag, and stores key information acquisition means for acquiring key information and verification information corresponding to the key information. A collation information storage means, a collation means for detecting a match / mismatch between the key information from the key information acquisition means and the collation information from the collation information storage means, and a match detection from the collation means, A control unit that enables transmission of the identification information from the IC tag, and an identification information transmission suppression that prohibits transmission of the identification information from the IC tag when a predetermined condition is satisfied after receiving a coincidence detection from the verification unit Means.

  According to the present invention, since the identification information stored in the IC tag is output only after the key information of the key information acquisition means matches the previously stored verification information, the identification information is illegally transmitted from the IC tag. In addition, the burden for putting the portable terminal device in a suppressed state is small, and the security of the portable terminal device can be enhanced without impairing the convenience for the user.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

(Embodiment 1)
FIG. 1 is a block diagram of mobile terminal apparatus 100 according to Embodiment 1 of the present invention.

  The mobile terminal device 100 includes a key information acquisition unit 101, a verification information storage unit 102, a verification unit 103, a control unit 104, an IC tag 105, and a timer unit 106.

  The key information acquisition unit 101 acquires and stores information for identifying the user himself / herself. In this specification, information given to identify the user is referred to as key information. This key information has a correspondence relationship with the collation information stored in advance in the collation information storage unit 102. The match / mismatch between the key information and the collation information is output to the IC tag 105 via the control unit 104.

  The IC tag 105 includes an IC memory 107 in which identification information for identifying the user of the mobile terminal device 100 is stored, and an antenna 108 for receiving power from outside and transmitting / receiving signals to / from the outside. ing.

  The control unit 104 receives the coincidence signal from the collation unit 103, sets the determination storage unit 109 in a set state, and outputs a permission signal for permitting activation to the IC tag 105. On the other hand, the mismatch signal from the matching unit 103 is output to the control unit 104 via the OR circuit 110, the determination storage unit 109 is reset, and the control unit 104 outputs a non-permission signal that immobilizes the IC tag 105. .

  The timer unit 106 is activated by the coincidence signal from the collation unit 103, outputs after a predetermined time, and resets the determination storage unit 109 of the control unit 104 via the OR circuit 110. The OR circuit 110 receives a cash settlement completion confirmation signal from the settlement machine 111. Details of the settlement machine 111 will be described later.

  The identification information stored in the IC memory 107 of the IC tag 105 is unique information for identifying the mobile terminal device 100 in transactions such as cashless settlement using the mobile terminal device 100, and is a credit card. Or the card number of a cash card.

  The key information of the key information acquisition unit 101 and the collation information of the collation information storage unit 102 include an ID number that can identify the user, a personal identification number that only the user knows, and fingerprint information that is information about the physical characteristics of the user. Voiceprint information, retinal patterns, vein patterns, etc. can be used.

  FIG. 2 is a flowchart for explaining the operation of mobile terminal apparatus 100 according to Embodiment 1. Hereinafter, the operation of the mobile terminal device 100 will be described with reference to FIGS. 1 and 2.

  First, the mobile terminal device 100 determines whether key information has been input from the outside (ST201). If the determination result is YES, the key information acquisition unit 101 acquires key information and outputs it to the collation unit 103. Accordingly, the collation information storage unit 102 outputs collation information stored in advance to the collation unit 103.

  Collation section 103 collates whether or not the key information matches the collation information (ST202). If a match is detected as a result of the collation (ST202: YES), collation section 103 outputs a permission signal indicating that activation of IC tag 105 is permitted to control section 104 (ST203).

  In step ST203, the following control is executed in addition to the activation control of the IC tag 105 described above. That is, the timer unit 106 is activated in response to the coincidence output from the collation unit 103. The timer unit 106 outputs a time-up signal when a predetermined time, which is predetermined as a sufficient time for completing the transaction once started, has elapsed. Furthermore, in this step ST203, the control state of the portable terminal device 100 is set so that the end is detected when the transaction ends. For example, when the user selects cashless settlement and the settlement machine 111 finishes the settlement, and the settlement machine 111 outputs a confirmation signal indicating the completion of the cashless settlement, this is detected by the mobile terminal device 100. .

  The permission signal from the collation unit 103 sets the determination storage unit 109 of the control unit 104 and outputs the set output of the determination storage unit 109 to the IC tag 105. Accordingly, the IC tag 105 is permitted to operate and becomes operable. This state is shown as step ST204 in FIG.

  When the IC tag 105 that has become operable in step ST204 receives electromagnetic waves from the outside by the antenna 108 and obtains drive power and establishes drive power for driving a circuit such as the IC memory 107, the IC tag 105 is connected to the antenna 108. The identification information stored in the IC memory 107 is transmitted to the outside via (ST204). Accordingly, the mobile terminal device 100 can transmit an identification signal necessary for the transaction to the outside.

  In FIG. 2, step ST203 is shown separately. This is because the mobile terminal device 100 does not receive electromagnetic waves from the outside even if the control unit 104 or the like, the previous stage of the IC tag 105 in FIG. Even if it cannot be received, the permission state is stored, and if the operation is permitted, the IC tag 105 is immediately operated.

  In this way, the identification information is transmitted from the IC tag 105 and the transaction is terminated. For example, when the user selects cashless settlement and the settlement operation is terminated, a settlement end signal is input from the settlement machine 111 to the mobile terminal device 100. Is done. Alternatively, even when the transaction end signal is not input due to some accident or the like, the timer unit 106 outputs a time-up signal when a predetermined time has elapsed after the permission signal is issued by the verification unit 103. The generation of these transaction end signals and time-up signals is constantly monitored as described above (ST203).

  In step ST205, the settlement end signal from the settlement machine 111 and the time-up signal from the timer unit 106 reset the determination storage unit 109 via the OR circuit 110. Thereby, even if the IC tag 105 is set to the transmission permission state of the identification signal and the transaction is once started, the identification signal is not transmitted from the IC tag 105 when the settlement is completed and the transaction is completed. In addition, when the transaction condition once confirmed by the permission signal from the verification unit 103 cannot be confirmed for some reason, the time from the timer unit 106 is reached if a predetermined time elapses after the permission signal is generated. The up signal is output and the identification signal is not transmitted so that it is not permitted. As a result, the risk that the identification signal is transmitted from the IC tag 105 over a long period of time unexpected by the user and used illegally is reduced.

  Thus, automatically setting the determination storage unit 109 to the reset state by the output of the timer unit 106 means that the portable terminal device 100 is automatically set to the suppression state with respect to the transmission of the identification information of the IC tag 105. This improves the convenience of the user.

  In FIG. 1, the mismatch output that is output when the mismatch between the key information and the verification information is detected by the verification unit 103 is also input to the determination storage unit 109 via the OR circuit 110 as a reset output. This is because once a coincidence output occurs, if a disagreement is detected for some reason, transmission of an identification signal from the IC tag 105 is prohibited, and safety priority control of the transaction is performed.

  As described above, according to the first embodiment, since the identification information is transmitted from the IC tag 105 only after the matching between the key information and the verification information is confirmed by the verification unit 103, the identification information is leaked to a third party. Or being illegally acquired. In addition, even if a match output is output from the collating unit 103 and the identification information can be sent from the IC tag 105 once, a predetermined condition, for example, a condition that the transaction has been completed successfully, or some cause When it is detected that a transaction has not been completed within a predetermined time determined by the timer unit 106, the IC tag 105 is automatically disabled so that identification information cannot be transmitted. It is possible to put the mobile terminal device in a suppressed state without any burden, and it is possible to increase the security of the mobile terminal device without impairing the convenience for the user.

(Embodiment 2)
Next, a second embodiment of the present invention will be described. FIG. 3 is a block diagram of mobile terminal apparatus 300 according to Embodiment 2. 3, the same parts as those in FIG. 1 are denoted by the same reference numerals, and detailed description thereof is omitted.

  Compared to the first embodiment, the second embodiment is different in that key information is stored in advance in an IC tag 302 formed separately from the mobile terminal device 300. The IC tag 302 has the same configuration as that of the IC tag 105 in Embodiment 1 in that an antenna is built in and key information stored in the built-in IC chip is transmitted to the outside with power received by the antenna. The key information is read into the key information acquisition unit 301 by bringing the key information storage IC tag 302 configured in this way closer to the mobile terminal device 300. The IC tag reader / writer 303 is a device provided in the vicinity of the checkout machine 111, and reads and writes information stored in the IC tag. The IC tag reader / writer 303 has a built-in antenna 304, and the antenna 304 can supply power to the key information storage IC tag 302 and transmit / receive signals. The antenna 304 is also used to supply power to the IC tag 105 and receive an identification signal.

  FIG. 4 is a schematic diagram showing the relationship between the key information storage IC tag 302 and the mobile terminal device 300 in the second embodiment. The key information storage IC tag is built in a ring 400 that is an accessory worn on the user's index finger. When the user holds the mobile terminal device 300 in the palm of the hand, the key information storage IC tag 302 becomes a mobile terminal. The key information can be read by approaching the key information acquisition unit 301 built in the apparatus 300.

  Now, when the user wearing the ring 400 grasps the portable terminal device 300 and approaches the IC tag reader / writer 303, the electromagnetic wave from the antenna 304 is received by the key information storage IC tag 302, and the power of the key information storage IC tag 302 is supplied. Is established, the key information storage IC tag 302 sends the user's key information stored in advance to the outside. Accordingly, key information is acquired by the key information acquisition unit 301 built in the mobile terminal device 300.

  When the key information is acquired by the key information acquisition unit 301, this key information is verified with the verification information stored in the verification information storage unit 102, and control operations such as whether or not this transaction is possible are described below. This is the same as the case of 1.

  In the case of the second embodiment, the user can input a key only by bringing the key information storage IC tag 302 and the mobile terminal device 300 close to each other, such as holding the key information storage IC tag with the palm of the finger. Therefore, the user does not need to input special key information, and the convenience for the user is improved. In addition, it is possible to force the user to make a transaction only when the key information storage IC tag and the mobile terminal device 300 are brought close to each other, and within the allowable range from the user's burden. Can be realized relatively easily. Therefore, as soon as the key information storage IC tag 302 and the mobile terminal device 300 are separated from each other by a predetermined distance, a mismatch signal (non-permission signal) from the matching unit 103 in FIG. 3 is output to the determination storage unit 109 via the OR circuit 110, The control unit 104 is reset and the IC tag 105 is immobilized, so that the mobile terminal device 300 can be easily operated with an emphasis on transaction safety.

  In the second embodiment, the key information storage IC tag 302 is shown as a non-contact type IC tag, but this is formed in a so-called memory card type and is carried by a card slot provided in a part of the portable terminal device 300. The terminal device 300 may be detachable.

  In each of the above embodiments, the key information and the corresponding verification information include so-called ID numbers and passwords given to each user, or so-called biometrics such as fingerprint / voice / retinal or vein patterns. It can be adopted.

  In FIG. 4, the mobile terminal device 300 is shown as a foldable mobile phone. In this case, when the user inputs an ID number or a password as key information, the input key of the mobile phone can be used. In addition, when using voice or a voiceprint as key information, a sound collection unit such as a microphone of a mobile phone can be used.

  A key information acquisition unit 101 may be configured by incorporating a near-infrared sensor into a normal mobile phone, and a user may be identified by a vein pattern.

  In addition, it is safe to update the verification information periodically or from time to time when it is used for transactions. In this update operation, the verification unit 103 detects that the key information matches the verification information. It should be allowed in some cases.

  INDUSTRIAL APPLICABILITY The present invention is useful for improving security without sacrificing user convenience when used for transactions using a mobile terminal device.
