JP5262967B2 - Mobile terminal, authentication method and program - Google Patents

Description

  The present invention relates to a mobile terminal that authenticates a caller, an authentication method, and a program.

  In recent years, a “caller number notification” service that displays a caller's telephone number when a call is received has become widespread. By using the “caller ID notification” service, it is possible to identify who the incoming call is from.

  However, since the caller number can be set to “not notify” in the service, when “not notify caller number” is set, the caller cannot be specified by display.

  In such a situation, in order to identify the other party, there is no choice but to confirm the voice of the other party with the ear of the recipient. However, there is a limit to specifying the other party with the human ear. For this reason, recently, crimes such as “I'm fraudulent”, such as making a phone call while pretending to be a relative and cheating money, have also occurred frequently.

  In view of this, there has been considered a system for authenticating a call partner by comparing the voice print data of the call partner's voice with previously stored voice print data (see, for example, Patent Document 1).

JP 2006-38955 A

  However, in a system such as that described in Patent Document 1, even if the other party is not authenticated, the voice from the receiver may be transmitted to the sender. In this case, there is a problem that information on the receiving side is known to an unknown call partner.

  The objective of this invention is providing the portable terminal, authentication method, and program which solve the subject mentioned above.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a diagram showing an embodiment of a portable terminal of the present invention.

  As shown in FIG. 1, this embodiment includes a memory 101, a receiving unit 102, a voiceprint data creating unit 103, a user identification information reading unit 104, a display unit 105, and a sound collection control unit 106. Yes. FIG. 1 shows only the constituent elements according to the present invention among the constituent elements of the portable terminal 100.

  The memory 101 stores in advance the voice print data of the other party and user identification information that can identify the other party in association with each other.

  FIG. 2 is a diagram showing an example of correspondence between voiceprint data stored in the memory 101 shown in FIG. 1 and user identification information.

  In the memory 101 shown in FIG. 1, registered voiceprint data and user identification information are stored in association with each other as shown in FIG.

  The registered voiceprint data is voiceprint data created by the voiceprint data creation unit 103 from the voice received from the other party. In FIG. 2, the registered voiceprint data is displayed as “data A” or the like, but this is displayed for convenience of explanation, and the voiceprint data itself is actually stored. Further, a plurality of registered voiceprint data may be stored for one user identification information. It goes without saying that the plurality of registered voiceprint data are voiceprint data of one person, but are created with a plurality of patterns (under the environment).

  The user identification information is information that can identify the calling party (user) that has emitted the voice that is the basis of the registered voiceprint data. Note that the user identification information may be information that allows the person who operates the mobile terminal 100 to identify the call partner, and may be a name, a nickname, or the like.

  For example, registered voiceprint data “Data A” and user identification information “Taro Nihon” are stored in association with each other. This indicates that the voice print data of “Taro Nihon” is registered as “Data A”. Also, registered voiceprint data “Data B” and user identification information “Kanto Hanako” are stored in association with each other. This indicates that voice print data of “Kanto Hanako” is registered as “Data B”. Also, registered voiceprint data “data C” and user identification information “Jiro Tokyo” are stored in association with each other. This indicates that the voice print data of “Jiro Tokyo” is registered as “Data C”.

  FIG. 3 is a diagram showing another example of association between voiceprint data stored in the memory 101 shown in FIG. 1 and user identification information.

  As shown in FIG. 3, the memory 101 shown in FIG. 1 stores registered voiceprint data, user identification information, a telephone number, and an e-mail address in association with each other. The correspondence between the user identification information, the telephone number, and the e-mail address may be a commonly used telephone directory. The phonebook is associated with registered voiceprint data.

  The registered voiceprint data is the same as that shown in FIG.

  The user identification information is the same as that shown in FIG.

  The telephone number is the telephone number of the other party.

  The e-mail address is the e-mail address of the call partner.

  For example, registered voiceprint data “data A”, user identification information “Taro Nihon”, telephone number “09011111111”, and e-mail address “nihon@aa.ne.jp” are stored in association with each other. This means that the voice print data of “Taro Nihon” who owns the terminal whose telephone number is “09011111111” and whose e-mail address is “nihon@aa.ne.jp” is registered in “Data A”. Show. In addition, registered voiceprint data “data B”, user identification information “Kanto Hanako”, telephone number “08099999999”, and e-mail address “hanahana@bb.ne.jp” are stored in association with each other. This is because the voiceprint data of “Kanto Hanako” who owns the terminal whose telephone number is “08099999999” and whose e-mail address is “hanahana@bb.ne.jp” is registered in “Data B”. Show. Also, registered voiceprint data “data C”, user identification information “Jiro Tokyo”, telephone number “090555555555”, and e-mail address “jiro@cc.ne.jp” are stored in association with each other. This is because the voiceprint data of “Jiro Tokyo” who owns the terminal whose telephone number is “090555555555” and whose e-mail address is “jiro@cc.ne.jp” is registered in “Data C”. Show.

  The receiving unit 102 receives voice from the other party during a call. In addition, the receiving unit 102 outputs the received voice to the voiceprint data creating unit 103.

  The voiceprint data creation unit 103 creates voiceprint data from the voice output from the reception unit 102. Any method for creating voiceprint data may be used. In the process of registering voiceprint data, the created voiceprint data is written into the memory 101 as registered voiceprint data. In the process of authenticating voiceprint data, the generated voiceprint data is output to the user identification information reading unit 104 as authentication voiceprint data.

  The user identification information reading unit 104 searches the memory 101 for registered voiceprint data that matches the authentication voiceprint data output from the voiceprint data creation unit 103. In addition, when the registered voiceprint data matching the authentication voiceprint data can be searched from the memory 101, the user identification information reading unit 104 reads the user identification information stored in association with the registered voiceprint data from the memory 101. read out. In addition, the user identification information reading unit 104 outputs the read user identification information to the display unit 105. If the registered voiceprint data matching the authentication voiceprint data cannot be retrieved from the memory 101, the user identification information reading unit 104 outputs a message to that effect to the display unit 105.

  When the user identification information is output from the user identification information reading unit 104, the display unit 105 displays the user identification information. When the fact that the registered voiceprint data could not be retrieved is output from the user identification information reading unit 104, that fact (for example, “no matching voiceprint data exists”) is displayed. The display unit 105 may be a general display.

  The sound collection control unit 106 controls the function of a sound collection function (for example, a microphone) included in the mobile terminal 100. In the process of authenticating voiceprint data, the sound collection control unit 106 disables the sound collection function from when the mobile terminal 100 starts a call until the display unit 105 displays the user identification information.

  Below, the authentication method in this form is demonstrated. The authentication method (process) described below may be automatically performed when a call is started, or when a predetermined operation is performed by a person who operates the mobile terminal 100 It may be implemented only for this.

  FIG. 4 is a flowchart for explaining an authentication method in portable terminal 100 shown in FIG.

  When the call is started (step S1), it is determined whether or not the registration function is ON (valid) (step S2). Whether or not the registration function is ON may be determined when a predetermined operation is performed by a person who operates the mobile terminal 100 when the call is started or during the call. For example, the registration function may be turned on when a predetermined key (for example, “0” key) is pressed when an incoming call is received or during a call.

  If it is determined that the registration function is ON, voiceprint data registration processing is performed (step S3).

  On the other hand, if it is determined that the registration function is not ON, voiceprint data authentication processing is performed (step S4).

  Below, the voiceprint data registration process of step S3 is demonstrated.

  FIG. 5 is a flowchart for explaining the voiceprint data registration process in step S3 of FIG.

  First, voiceprint data is created by the voiceprint data creation unit 103 as registered voiceprint data from the voice received by the receiving unit 102 (step S31). At this time, the call partner may be asked to say a predetermined phrase (for example, “Hello” or “Yes yes”) and the registered voiceprint data may be created from the voice.

  Then, the created registered voiceprint data is written into the memory 101 by the voiceprint data creation unit 103 (step S32). At this time, it is stored in the memory 101 in association with the user identification information of the calling party that has emitted the voice.

  Below, the voiceprint data authentication process of step S4 is demonstrated.

  FIG. 6 is a flowchart for explaining the voiceprint data authentication process in step S4 of FIG.

  First, the sound collection function provided in the portable terminal 100 is disabled by the sound collection control unit 106 (step S41). Here, the sound collection function may be disabled by the sound collection control unit 106 only when the incoming call from the other party is a caller ID non-notification.

  Subsequently, voiceprint data is created from the voice received by the receiving unit 102 as authentication voiceprint data by the voiceprint data creating unit 103 (step S42).

  Then, registered voiceprint data that matches the authentication voiceprint data created by the voiceprint data creation unit 103 is searched from the memory 101 by the user identification information reading unit 104 (step S43). Here, even if the registered voiceprint data that does not completely match the authentication voiceprint data is not searched, the authentication voiceprint data and the registered voiceprint data are compared at an arbitrary point, and both are compared with a preset threshold value or more. If a match is found, it may be determined that registered voiceprint data matching the authentication voiceprint data has been found.

  When registered voiceprint data matching the authentication voiceprint data is retrieved (Yes in step S44), user identification information stored in association with the retrieved registered voiceprint data is stored in the memory by the user identification information reading unit 104. 101 is read out (step S45).

  Then, the user identification information read from the memory 101 is displayed on the display unit 105 (step S46).

  FIG. 7 is a diagram illustrating an example of a screen of the display unit 105 on which user identification information is displayed.

  As shown in FIG. 7, the display unit 105 displays the user identification information read from the memory 101, that is, the other party's user. In the example shown in FIG. 7, the user identification information read from the memory 101 is “Nippon Taro” and “Taro Nihon is a phone call” is displayed.

  Further, after the user identification information is displayed on the display unit 105, the sound collection function of the portable terminal 100 is validated by the sound collection control unit 106 (step S47).

  On the other hand, when the registered voiceprint data that matches the authentication voiceprint data is not searched (No in step S44), the fact that the search was not possible is displayed on the display unit 105 (step S48).

  FIG. 8 is a diagram illustrating an example of a screen of the display unit 105 that displays that the user identification information could not be searched.

  As shown in FIG. 8, the display unit 105 displays that user identification information could not be retrieved. In the example shown in FIG. 8, “No matching voice print data” is displayed.

  If the authentication process described with reference to FIGS. 4 to 6 is not performed, a general call can be made.

  The above-described processing of the mobile terminal 100 may be performed by a logic circuit manufactured according to the purpose. Further, a program in which processing content is described as a procedure may be recorded on a recording medium readable by the portable terminal 100, and the program recorded on the recording medium may be read by the portable terminal 100 and executed. The recording medium readable by the portable terminal 100 refers to a removable recording medium such as a memory card that can be attached to the portable terminal 100, a memory such as a ROM or a RAM built in the portable terminal 100, an HDD, or the like. . The program recorded on the recording medium is read by a CPU (not shown) in the portable terminal 100, and the same processing as described above is performed under the control of the CPU. Here, the CPU operates as a computer that executes a program read from a recording medium on which the program is recorded.

  In this way, the mobile terminal has a voiceprint collation function, and by making the judgment result clear to the user, it is possible to prevent the user from being damaged by fraud etc. It is possible to prevent the other party from knowing the user information.
