  However, in a conventional system, a person other than the owner or a registrant (for example, a family member) uses the mobile terminal device illegally due to loss or theft of the mobile terminal device equipped with an IC tag. There is a risk that data such as personal information is transmitted from the IC tag. Simply mounting an IC tag on a portable terminal device increases the convenience of the owner or registrant, but requires careful attention regarding use and management.

  You can use a password to suppress the operation of the mobile terminal device body, but for practical purposes, when the owner or registrant expects theft or loss and carries the mobile terminal device body in a suppressed state beforehand There is little possibility that a portable terminal device equipped with an IC tag is used illegally if it is in the hands of a third party. On the other hand, carrying around in a state where the mobile terminal device cannot be used (that is, in a suppressed state) impairs user convenience.

  The present invention has been made in view of this point, and an object of the present invention is to provide a mobile terminal device with an IC tag that improves security without impairing user convenience.

  The portable terminal device of the present invention includes an acquisition unit that acquires authentication information, a storage unit that stores verification information to be verified against the authentication information, a verification unit that matches the authentication information and the verification information, and the verification A configuration is adopted that includes control means for permitting transmission of notification information when authentication information matches the verification information, and an IC tag for transmitting the notification information.

  According to the present invention, since the transmission of the IC tag is permitted only when the authentication information acquired by acquiring the authentication information matches the collation information stored in the storage means, the portable terminal device can be used without being used. Even if not, information is not illegally transmitted from the IC tag by a third party, so that it is possible to provide a portable terminal device with an IC tag that improves security without impairing the convenience of the user.

  The gist of the present invention is that the authentication information acquired by acquiring the authentication information and the collation information stored in the storage means are not matched until the IC tag transmission is permitted, and the security of the user is not impaired. Is to improve.

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

  First, a configuration of a mobile terminal device including the non-contact IC tag according to the present embodiment will be described with reference to FIG.

  As illustrated in FIG. 1, the mobile terminal device 100 includes an authentication information acquisition unit 101, a control unit 102, a storage unit 103, a verification unit 104, and an IC tag 105.

  The authentication information acquisition unit 101 is, for example, an input device such as a character input button when the authentication information is a password, and is a scanner or an infrared sensor when the authentication information is a fingerprint pattern or a vein pattern. The authentication information section acquisition unit 101 is a sound collecting device such as a microphone when the authentication information is voice information, and an optical scanner such as a camera when the authentication information is a retina pattern.

  When the authentication information acquisition unit 101 acquires the authentication information, the authentication information acquisition unit 101 sends the authentication information to the control unit 102.

  When the control unit 102 acquires the authentication information from the authentication information acquisition unit 101, the control unit 102 sends a verification command signal instructing the verification information and the verification information stored in the storage unit 103 to be verified to the verification unit 104. The storage unit 103 stores in advance verification information of the same type as the authentication information acquired by the authentication information acquisition unit 101. This verification information stores authentication information acquired in advance using the authentication information acquisition unit 101. It is.

  When the verification unit 104 receives the authentication information and the verification command signal from the control unit 102, the verification unit 104 acquires the verification information from the storage unit 103 and performs verification between the authentication information and the verification information. When the verification information matches the verification information as a result of the verification, the verification unit 104 sends a verification match signal to the control unit 102. On the other hand, when the authentication information and the verification information do not match, verification unit 104 sends a verification mismatch signal to control unit 102.

  When the control unit 102 receives the verification coincidence signal from the verification unit 104, the control unit 102 outputs an operation permission signal to the IC tag. On the other hand, when receiving the verification mismatch signal from the verification unit 104, the control unit 102 outputs an operation non-permission signal to the IC tag 105.

  The IC tag 105 becomes operable when it receives an operation permission signal from the control unit 102. In this operable state, when an electromagnetic wave for generating electric power necessary for operation is received by an antenna (not shown) included in the IC tag 105, the IC tag 105 stores a storage unit (see FIG. The information stored in (not shown) is transmitted.

  When the IC tag 105 is supplied with power from the power source of the mobile terminal device 100 main body, when the operation permission signal is received from the control unit 102, that is, when the IC tag 105 becomes operable, the IC tag 105 may transmit information stored in a storage unit (not shown). Further, the IC tag 105 may be configured to repeatedly transmit information when the IC tag 105 is in an operable state and is in a state where the operating conditions are met.

  Further, the control unit 102 may include a timer unit (not shown), and may perform control such that the operable state of the IC tag 105 does not continue for a certain period or more. In this control, for example, the IC tag 105 is configured to maintain the operable state while receiving the operation permission signal from the control unit 102, and the control unit 102 is configured to repeatedly transmit the operation permission signal for a certain period. Can be realized. In addition, this control is configured such that the IC tag 105 is kept in an operable state once receiving an operation permission signal from the control unit 102, and becomes inoperable when an operation non-permission signal is received. This can be realized by sending an operation non-permission signal after a certain period of time has passed since the operation permission signal was sent, or when a predetermined condition is satisfied.

  In addition, in order to avoid that the information on the authorized person registered in advance, that is, the verification information is changed by a third party, the information on the authorized person can be changed only once at the beginning or only by the authorized person. It is necessary to. For example, when changing the information of the permitter, the information of the permitter registered by the permitter is given again to the control unit 102 using the authentication information acquisition unit 101 and collated with the given information. It is only necessary that the collation information can be changed only when the collation unit 104 collates information and the collation is successful.

  Next, an example of an embodiment in which the mobile terminal device 100 is used for cashless settlement will be described with reference to FIG.

  In the case of cashless settlement of the mobile terminal device 100, the authentication information and the verification information are, for example, fingerprint information of a user permitted to use the mobile terminal device 100. Further, the information stored in the IC tag 105 is, for example, a cash card number, a personal identification number, or the like.

  First, a user who performs cashless settlement using the mobile terminal device 100 uses the authentication information acquisition unit 101 to read authentication information such as his / her fingerprint information.

  In step ST201, when authentication information is input from authentication information acquisition unit 101 (step ST201: YES), control unit 102 instructs verification of the authentication information and the verification information stored in storage unit 103. The command signal is sent to the verification unit 104.

  In step ST202, when the verification unit 104 receives the authentication information and the verification command signal from the control unit 102, the verification unit 104 acquires the verification information from the storage unit 103 and performs verification between the authentication information and the verification information.

  As a result of the collation, when the authentication information matches the collation information (step ST202: YES), the collation unit 104 sends the collation coincidence information to the control unit 102. When the control unit 102 receives the verification coincidence signal from the verification unit 104, the control unit 102 outputs an operation permission signal to the IC tag. Then, when the IC tag 105 receives the collation coincidence signal from the control unit 102, the IC tag 105 becomes operable, that is, the transmission operation is turned on (step ST203).

  Next, the IC tag 105 transmits information stored in a storage unit (not shown) included in the IC tag 105 (step ST204).

  Then, the control unit 102 sends an operation non-permission signal to the IC tag 105 after a certain period of time has passed since the operation permission signal was sent, or when a predetermined condition is satisfied, for example, when cashless settlement is completed. Then, the IC tag 105 is in an inoperable state, that is, the transmission operation is OFF (step ST205).

  On the other hand, when there is no input of authentication information from the authentication information acquisition unit 101 (step ST201: NO), and when the authentication information does not match the verification information (step ST202: NO), the IC tag 105 transmits information. The process ends without When there is no input of authentication information from the authentication information acquisition unit 101 (step ST201: NO), and when the authentication information and the verification information do not match (step ST202: NO), a standby state in which input from the user is always requested. Therefore, the process may return to step ST201.

  In the embodiment as described above, when the authentication information acquisition unit 101 is a scanner or the like that can read the user's fingerprint, when cashless settlement is performed using the mobile terminal device 100 including the IC tag 105, the settlement is performed. The user who wants to perform authentication causes the authentication information acquisition unit 101 to read his / her fingerprint by placing his / her finger. The portable terminal device 100 collates the fingerprint of the given user with the fingerprint of the authorized person registered in advance, and if the collation of the fingerprint is successful, the transmission operation of the IC 105 is permitted, and if the collation fails, the IC tag The control 105 may perform control not to perform the communication operation.

  In the above-described embodiment, when the authentication information acquisition unit 101 is a near-infrared sensor capable of reading the vein pattern of the user's finger, the user who wants to perform cashless settlement uses his / her information as his / her own information. Similar to the case of reading a fingerprint, the mobile terminal device 100 can read a finger vein pattern using the authentication information acquisition unit 101. The mobile terminal device 100 may determine whether or not the person is a permitted person based on the given information, and may control the communication operation for the IC tag 105.

In the above-described embodiment, when the authentication information acquisition unit 101 is an optical scanner such as a camera that can read a human retina pattern, the cashless settlement using the portable terminal device 100 including the IC tag 105 is performed. Sometimes, the user causes his / her retina pattern to be read by the authentication information acquisition unit 101 as his / her information. The portable terminal device 100 collates the given retinal pattern with the retinal pattern of the authorized person registered in advance, and controls the communication operation of the IC tag 105 according to the collation result. In other words, the control of permitting the communication operation of the IC tag 105 may be performed if the retina pattern collation is successful, and the IC tag 105 may be controlled to suppress the communication operation if the collation fails. The mounting of a camera on a portable terminal device has already been put into practical use, and in addition to this, the present invention can be realized in combination with an image processing technique for extracting a retinal pattern.

  In the above-described embodiment, when the authentication information acquisition unit 101 is a sound collection device that can acquire sound, the user can acquire authentication information as his / her information during cashless settlement using the IC tag 105. The user's voice is acquired from the unit 101. The mobile terminal device 100 collates the given voice with voice information such as the volume, sound quality, and voiceprint of the authorized person registered in advance, and controls the communication operation of the IC tag 105 according to the collation result. That is, if the voice collation is successful, the communication operation of the IC tag 105 may be permitted, and if the collation fails, the IC tag 105 may be controlled not to perform the communication operation. Since a sound collection unit such as a microphone is always equipped for a call that is an original function of the mobile terminal device, it is not necessary to newly equip the authentication information acquisition unit 101 and is close to the method of realizing the present invention. One of the methods.

  In the above-described embodiment, when the authentication information acquisition unit 101 is an input device that can acquire a personal identification number, such as a character input button for inputting alphanumeric characters, hiragana, kanji, etc., the IC tag 105 At the time of cashless settlement using the user, the user inputs the personal identification number from the authentication information acquisition unit 101 as his / her information and gives it to the portable terminal device 100. The mobile terminal device 100 collates the given password with the password of the authorized person registered in advance, and controls the communication operation of the IC tag 105 based on the result of the comparison. That is, if the collation of the password is successful, the communication operation of the IC tag 105 is permitted, and if the collation fails, the IC tag 105 may be controlled not to perform the communication operation. Since an input unit such as a character input button is always provided for operation and incoming / outgoing calls in the mobile terminal device, there is no need to newly provide an input unit as the authentication information acquisition unit 101, and the method for realizing the present invention This is one of the methods close to.

  In the above-described embodiment, the time for the communication operation of the IC tag 105 is limited from the time when the identification of whether or not the person is a permitted person until the time when the cashless checkout is completed within a preset time. May be given. In other words, in the case where there is a time difference until the authorized person is identified in the mobile terminal device 100 and actual cashless settlement is performed (for example, the cashless settlement is performed at the station ticket gate using the retina pattern as the identifying means). ), The user who wants to perform cashless check-up can confirm whether or not the user is authorized in advance and allow transmission / reception of the IC tag 105.

  Next, an example of the external configuration of the mobile terminal device 100 will be described with reference to FIGS. 3 and 4.

  As shown in FIGS. 3 and 4, the mobile terminal device 100 has a structure that can be folded in two.

It is installed.

  In addition, the mobile terminal device 100 has an authentication information acquisition unit 101B (for example, a camera), an input button as the authentication information acquisition unit 101C, and an authentication information acquisition unit 101D as shown in FIG. A microphone and an IC tag 105B are provided.

  Note that either one of the IC tag 105A and the IC tag 105B may be provided. Further, when both the IC tag 105A and the IC tag 105B are provided, the IC tag 105A or the IC tag 105B depending on the state of the communication terminal device 100 (for example, the folded state and the expanded state). It is good also as composition which operates.

  As described above, according to the present embodiment, the IC tag 105 is operable only after the authentication information from the authentication information acquisition unit 101 matches the verification information stored in the storage unit 103. A non-contact IC tag that improves security without sacrificing user convenience because information is not illegally transmitted from the IC tag 105 to a third party even if the portable terminal device cannot be used. An attached mobile terminal device can be provided.

  Note that the mobile terminal device 100 may include one unit or a plurality of units listed as the authentication information acquisition unit 101. When it is set as the structure provided with two or more, the portable terminal device 100 can improve a specific precision by specifying an authorized person using a some judgment result.

  Further, in the method for realizing the present invention, the means for specifying the permitter is not limited to the one using the above-mentioned PIN or biometric technology, but the cashless is determined by some information given to the mobile terminal device by the user. Any means may be used as long as it is determined whether or not the person has the right to perform checkout, and as a result, the IC tag communication operation is permitted or suppressed.
