Description

  The present invention relates to an authentication system, an authentication server, an authentication method, and a program for confirming / certifying an identity.

  In many cases, a visiting visitor must prove the identity of the visitor to the visitor who receives the visitor at the place of visit. The only way for a visitor to prove his / her identity to an unspecified responder is to present his / her identification card or the like possessed by the visitor.

  However, since the respondent cannot determine whether the presented ID is credible, it cannot determine whether the visitor's identity is correct.

  Visitors can only verify their identity by self-reporting.

  There is biometric authentication as a reliable method for proving identity, but when this method is used, important biometric information must be disclosed to unspecified majority.

  In view of this, a system has been considered in which a visitor registers a visit schedule in advance and authenticates using biometric information as to whether or not the contents coincide with the contents registered at the visit destination (see, for example, Patent Document 1).

  In addition, a technique has been considered in which information for visitor authentication is transmitted in advance to the reception side of the visited site, and the visitor is authenticated on the reception side at the time of reception (for example, patent document) 2).

  In addition, a technique is conceived in which user biometric information is stored in advance in a database, and user authentication is performed using only biometric information stored in a matching portion designated by the user in the database ( For example, see Patent Document 3.)

JP 2003-114923 A JP 2003-108751 A JP 2007-11885 A

  However, the system described in Patent Document 1 has the following problems.

  In mail delivery, etc., only the address is known, or the address information may be delivered in an incomplete state, and it is difficult to uniquely identify the visited place. Even if you can identify the destination, you must know the system the visitor uses and make a visit reservation on that system, or make a reservation on all the systems that the visitor may be using. I must. Moreover, since it is necessary to register in advance, there is a possibility that a sudden change of a visitor or a visit destination cannot be handled.

  Further, the technique described in Patent Document 2 also has a problem that a reservation must be made in advance, which takes time. In addition, since the reception side holds personal information such as biometric information that should be kept secret for authentication of biometric information and the like, personal information may flow unnecessarily.

  Further, in a situation where a visitor cannot identify a visit destination, an authentication method that can be easily used even in a situation where an unspecified visitor proves his / her identity to an unspecified responder is required.

  Moreover, in the technique described in Patent Document 3, there is a problem that the user cannot receive authentication except in a place where a system for performing authentication is provided.

  An object of the present invention is to provide an authentication system, an authentication server, a certification method, and a program that solve the above-described problems.

  The attendant terminal 200 is a terminal possessed by an attendant who handles a visitor at a visit destination of the visitor. In addition, the client terminal 200 has a communication function.

  The authentication server 300 authenticates the visitor based on the voice data transmitted from the responder terminal 200. In addition, after performing authentication, the authentication server 300 transmits visitor information about the visitor to the receiver terminal 200.

  FIG. 2 is a diagram illustrating an example of an internal configuration of the visitor terminal 100 illustrated in FIG. 1.

  As shown in FIG. 2, the visitor terminal 100 shown in FIG. 1 is provided with a voice recognition unit 101 and a communication unit 102. FIG. 2 shows only the components related to the present invention among the components of the visitor terminal 100 shown in FIG.

  The voice recognition unit 101 recognizes a voice input from the outside and outputs it as voice data to the communication unit 102.

  The communication unit 102 transmits the voice data output from the voice recognition unit 101 to the authentication server 300. In addition, the communication unit 102 may transmit visitor terminal identification information given to the visitor terminal 100 in advance, which can identify the visitor terminal 100, to the authentication server 300.

  FIG. 3 is a diagram showing an example of the internal configuration of the customer terminal 200 shown in FIG.

  As shown in FIG. 3, the receiver terminal 200 shown in FIG. 1 is provided with a voice recognition unit 201, a communication unit 202, and a display unit 203. FIG. 3 shows only the constituent elements related to the present invention among the constituent elements of the receiver terminal 200 shown in FIG.

  The voice recognition unit 201 recognizes a voice input from the outside and outputs it as voice data to the communication unit 202.

  The communication unit 202 transmits the voice data output from the voice recognition unit 201 to the authentication server 300. In addition, the communication unit 202 outputs the visitor information transmitted from the authentication server 300 to the display unit 203.

  The display unit 203 displays visitor information output from the communication unit 202. The display unit 203 only needs to be able to display information in a recognizable manner, and may be a general display, for example.

  FIG. 4 is a diagram illustrating an example of an internal configuration of the authentication server 300 illustrated in FIG.

  As illustrated in FIG. 4, the authentication server 300 illustrated in FIG. 1 includes a database 301, a reference availability setting unit 302, an authentication unit 303, and a transmission unit 304. FIG. 4 shows only the components related to the present invention among the components of the authentication server 300 shown in FIG.

  The database 301 stores (registers) information related to visitors in advance.

  FIG. 5 is a diagram showing an internal structure of the database 301 shown in FIG.

  As shown in FIG. 5, the database 301 shown in FIG. 4 stores permission information, identification information, voice data, and visitor information in association with each other. The identification information, voice data, and visitor information are information stored in advance. Further, the permission information is information set by the reference availability setting unit 302.

  The permission information is information indicating whether identification information, voice data, and visitor information associated with the permission information can be referred to. In FIG. 5, “Yes” is indicated when reference is possible, and “No” is indicated when reference is impossible. Here, “can be referred to” indicates that the authentication unit 303 can refer to the voice print based on the voice data transmitted from the receiver terminal 200. That is, the authentication unit 303 cannot perform authentication using the identification information whose reference information is “No”, the association information of the voice data, and the visitor information.

  The identification information is information that can identify a visitor who emits the voice of the voice data associated with the identification information. For example, it may be a predetermined keyword such as a name, or may be visitor terminal identification information given in advance to the visitor terminal 100 possessed by the visitor.

  The voice data is voice data emitted by a visitor indicated by visitor information associated with the voice data. The voice data includes the voiceprint information of the visitor, and the authentication unit 303 performs voiceprint authentication using the voice data.

  The visitor information is information about a visitor who has the visitor terminal 100. It is not specified what kind of information it is, but it is information that can prove the identity of the visitor. For example, as shown in FIG. 5, the name of the visitor or the name of the company to which the visitor is stored may be stored. Moreover, the data of the visitor's face photograph may be included.

  The correspondence shown in FIG. 5 will be described as an example. The permission information “OK”, the identification information “A”, the voice data “a”, and the visitor information “Taro Yamada, XX Express” correspond to each other. Attached and stored. This is because the identification information for identifying the visitor emitting the voice of the voice data “a” is “A”, the visitor information is “Taro Yamada, XX Express”, and this correspondence can be referred to. Is shown. Further, permission information “NO”, identification information “B”, voice data “b”, and visitor information “Jiro Nihon, XX Transportation” are stored in association with each other. In this case, the identification information for identifying the visitor emitting the voice of the voice data “b” is “B”, the visitor information is “Jiro Nihon, XX Transportation”, and this correspondence cannot be referred to. It is shown that. In addition, permission information “No”, identification information “C”, voice data “c”, and visitor information “Saburo Kanto, ΔΔ Corporation” are stored in association with each other. This is because the identification information for identifying the visitor who emits the voice of the voice data “c” is “C”, the visitor information is “Kaburo Saburo, △△ Inc.”, and this correspondence cannot be referred to. It shows that there is. Further, permission information “OK”, identification information “D”, voice data “d”, and visitor information “Tokyo Hanako, □□ Electric Power” are stored in association with each other. This is because the identification information for identifying the visitor emitting the voice of the voice data “d” is “D”, the visitor information is “Tokyo Hanako, □□ Electric Power”, and this correspondence can be referred to. Is shown.

  In addition, the reference availability setting unit 302 sets whether or not the association stored in the database 301 can be referred to based on the identification information transmitted from the visitor terminal 100. Specifically, “permission information” associated with identification information that matches the identification information transmitted from the visitor terminal 100 is set to “permitted”. In addition, “permission information” that is “permitted” is set (updated) to “denied” at a predetermined timing. The predetermined timing may be after a predetermined time has elapsed after the “permission information” becomes “permitted”, or a predetermined signal is transmitted from the visitor terminal 100. The timing may be different, and is not particularly specified here.

  The authentication unit 303 searches the voice data transmitted from the terminal for the responder 200 from the correspondence stored in the database 301 and which can be referred to (“permission information” is “possible”). That is, the voiceprint authentication of the visitor is performed by searching the database 301 for voice data that matches the voice data transmitted from the terminal 200 for the visitor.

  The transmission unit 304 transmits the visitor information associated with the voice data searched by the authentication unit 303 to the receiver terminal 200.

  Hereinafter, a verification method for verifying the identity of a visitor in the first embodiment will be described.

  FIG. 6 is a sequence diagram for explaining a certification method for proving the identity of a visitor in the first embodiment. The scene is a scene in which a visitor possessing the visitor terminal 100 visits an attendant possessing the respondent terminal 200. In addition, there is a scene in which the visitor terminal 100 and the attendant terminal 200 are present at a position where the visitor terminal 100 and the attendant terminal 200 can recognize the voice uttered by the visitor.

  First, when the voice is recognized by the voice recognition unit 101 of the visitor terminal 100 by the voice of the visitor (step S1), the visitor identification information is transmitted from the communication unit 102 to the authentication server 300. (Step S2). This voice may be, for example, a voice in which a visitor gives his / her own name to an attendant. In that case, there is no need to speak specially.

  Further, as described above, the identification information transmitted here may be a word (keyword) uttered by the visitor, or may be the visitor terminal identification information of the visitor terminal 100. As long as the person can be identified. However, this identification information must be the same as the “identification information” stored in the database 301. A plurality of pieces of identification information may be used. For example, a combination of a visitor name and a keyword, or a combination of a visitor name and visitor terminal identification information may be used. At this time, these combinations need to be stored in the database 301 in advance. By using the combination, the search range can be narrowed down.

  When the identification information is transmitted from the visitor terminal 100 to the authentication server 300, the “permission information” stored in the database 301 in association with the identification information is stored in the database 301 based on the identification information. “Yes” is set (step S3). Thereby, it is possible to refer to the audio data associated with the identification information. For example, when the identification information transmitted from the visitor terminal 100 is “A”, the permission information associated with the identification information “A” stored in the database 301 is set to “permitted”. The FIG. 5 shows a case where the permission information associated with the identification information “A” is set to “permitted”. In the example shown in FIG. 5, the identification information “D” is transmitted from another visitor terminal, and the permission information associated with the identification information “D” is set to “permitted”. Has been.

  On the other hand, when the voice is recognized by the voice recognition unit 201 of the receiver terminal 200 (step S4), the recognized voice is transmitted as voice data from the communication unit 202 to the authentication server 300 (step S5). At this time, the voice recognized in step S4 is the same as the voice recognized by the visitor terminal 100 in step S1.

  When voice data is transmitted from the receiver terminal 200 to the authentication server 300, voice authentication is performed by the authentication unit 303 based on the voice data (step S6).

  The processing in step S6 will be specifically described.

  When voice data is transmitted from the receiver terminal 200, the voice data stored in the database 301 in the authentication unit 303 is associated with “permitted information” that is “permitted”. Therefore, a search is made for data that matches the voice data transmitted from the receiver terminal 200. For example, in the example illustrated in FIG. 5, the association in which the permission information is “OK” is that the audio data is “a” and the audio data is “d”. Therefore, when the voice data transmitted from the terminal 200 for the customer is “a”, a search is made for the voice data “a” from the two sets of associations.

  When an association whose voice data is “a” is searched, the visitor information (corresponding to the voice data “a”) of the correspondence is read from the database 301 by the transmission unit 304, and the responder (Step S7).

  When visitor information is transmitted from the authentication server 300 to the receiver terminal 200, the visitor information is displayed on the display unit 203 of the receiver terminal 200 (step S8).

  FIG. 7 is a diagram illustrating an example of display of visitor information on the display unit 203 of the receiver terminal 200.

  As shown in FIG. 7, the visitor information (see FIG. 5) stored in the database 301 is displayed on the display unit 203 shown in FIG. Here, “Name: Taro Yamada, Company name: XX Express” is displayed. In this way, the display unit 203 displays information that can verify the identity of the visitor transmitted from the authentication server 300. As described above, in addition to the information shown in FIG. 7, when visitor face photo data is transmitted from the authentication server 300, the face photo may be displayed.

  By referring to the visitor information displayed on the display unit 203, the responder can confirm the identity of the visitor. From the viewpoint of the visitor, the visitor information displayed on the display unit 203 can prove the visitor's identity.

Thereafter, the permission information set in step S3 to “permitted” stored in the database 301 is set to “not permitted” by the reference permission setting unit 302 (step S9). As described above, the timing of setting “No” may be after a predetermined time has elapsed after the permission information becomes “Yes”, or may be set in advance from the visitor terminal 100. This timing may be the timing at which this signal is transmitted, and is not particularly defined here.
(Second Embodiment)
Next, a second embodiment of the present invention will be described. The configuration of the authentication system is the same as that shown in FIG.

  FIG. 8 is a diagram illustrating an example of an internal configuration of the visitor terminal 100 according to the second embodiment.

  As shown in FIG. 8, the visitor terminal 100 according to the second embodiment includes a voice recognition unit 101, a communication unit 102, and a position information acquisition unit 103.

  The voice recognition unit 101 is the same as that shown in FIG.

  In addition to the functions shown in FIG. 2, the communication unit 102 transmits the location information of the visitor terminal 100 output from the location information acquisition unit 103 to the authentication server 300.

  The position information acquisition unit 103 acquires position information where the visitor terminal 100 exists. Further, the position information acquisition unit 103 outputs the acquired position information to the communication unit 102. The method by which the location information acquisition unit 103 acquires the location information where the visitor terminal 100 exists is not defined here. For example, the terminal 100 for visitors may be provided with a GPS (Global Positioning System) function and acquired by the function.

  FIG. 9 is a diagram illustrating an example of an internal configuration of the client terminal 200 according to the second embodiment.

  As shown in FIG. 9, the receiver terminal 200 according to the second embodiment includes a voice recognition unit 201, a communication unit 202, a display unit 203, and a position information acquisition unit 204.

  The voice recognition unit 201 is the same as that shown in FIG.

  The display unit 203 is the same as that shown in FIG.

  In addition to the functions shown in FIG. 3, the communication unit 202 transmits the location information of the client terminal 200 output from the location information acquisition unit 204 to the authentication server 300.

  The position information acquisition unit 204 acquires position information where the receiver terminal 200 exists. Further, the receiver terminal 200 outputs the acquired position information to the communication unit 202. The method by which the location information acquisition unit 204 acquires location information where the receiver terminal 200 exists is not defined here. For example, like the position information acquisition unit 103 illustrated in FIG. 8, the receiver terminal 200 may be provided with a GPS function and acquired by the function.

  FIG. 10 is a diagram illustrating an example of an internal configuration of the authentication server 300 according to the second embodiment.

  As shown in FIG. 10, the authentication server 300 according to the second embodiment includes a database 301, a reference availability setting unit 302, an authentication unit 303, a transmission unit 304, and a range determination unit 305. .

  The database 301 is the same as that shown in FIG.

  The reference availability setting unit 302 is the same as that shown in FIG.

  The authentication unit 303 is the same as that shown in FIG.

  The transmission unit 304 transmits visitor information to the receiver terminal 200 based on the determination result of the range determination unit 305 in addition to the functions shown in FIG. Specifically, the visitor information is transmitted to the responder terminal 200 only when the range determining unit 305 determines that the visitor terminal 100 is within a predetermined distance range from the responder terminal 200.

  The range determination unit 305 receives the location information of the visitor terminal 100 together with the identification information from the visitor terminal 100, and the location information of the visitor terminal 200 together with the voice data from the attendant terminal 200. Based on the location information of the visitor terminal 100 and the location information of the attendant terminal 200 that has transmitted the voice data that can be referred to by the identification information transmitted from the visitor terminal 100, It is determined whether the service terminal 100 is within a predetermined distance range from the client terminal 200.

  Below, the certification | authentication method which proves the identity of the visitor in 2nd Embodiment is demonstrated.

  FIG. 11 is a sequence diagram for explaining a proving method for proving the identity of a visitor in the second embodiment. The scene is a scene in which a visitor possessing the visitor terminal 100 visits an attendant possessing the respondent terminal 200. In addition, there is a scene in which the visitor terminal 100 and the attendant terminal 200 are present at a position where the visitor terminal 100 and the attendant terminal 200 can recognize the voice uttered by the visitor.

  First, when the voice is recognized by the voice recognition unit 101 of the visitor terminal 100 by the voice of the visitor (step S11), the visitor acquired by the visitor identification information and position information acquisition unit 103 The location information of the user terminal 100 is transmitted from the communication unit 102 to the authentication server 300 (step S12). At this time, the timing of acquiring the location information of the visitor terminal 100 by the location information acquisition unit 103 is arbitrary. For example, it may be acquired at a predetermined cycle, or may be acquired at the timing when the voice in step S11 is recognized.

  The identification information transmitted here may be a word (keyword) uttered by the visitor as in the first embodiment, or may be the visitor terminal identification information of the visitor terminal 100. Anything that can identify a visitor is acceptable. However, this identification information must be the same as the “identification information” stored in the database 301. A plurality of pieces of identification information may be used. For example, a combination of a visitor name and a keyword, or a combination of a visitor name and visitor terminal identification information may be used. At this time, these combinations need to be stored in the database 301 in advance. By using the combination, the search range can be narrowed down.

  When the identification information and the position information are transmitted from the visitor terminal 100 to the authentication server 300, the reference availability setting unit 302 stores the identification information in association with the identification information in the database 301 based on the identification information. The “permission information” is set to “permitted” (step S13). Thereby, it is possible to refer to the audio data associated with the identification information. For example, when the identification information transmitted from the visitor terminal 100 is “A”, the permission information associated with the identification information “A” stored in the database 301 is set to “permitted”. The FIG. 5 shows a case where the permission information associated with the identification information “A” is set to “permitted”. In the example shown in FIG. 5, the identification information “D” is transmitted from another visitor terminal, and the permission information associated with the identification information “D” is set to “permitted”. Has been.

  On the other hand, when a voice is recognized by the voice recognition unit 201 of the terminal 200 for the responder (step S14), the recognized voice is transmitted as voice data from the communication unit 202 to the authentication server 300 (step S15). At this time, the voice recognized in step S14 is the same as the voice recognized by the visitor terminal 100 in step S11. Further, the location information of the client terminal 200 acquired by the location information acquisition unit 204 is transmitted from the communication unit 202 to the authentication server 300. At this time, the position information acquisition unit 204 can arbitrarily acquire the position information of the receiver terminal 200. For example, it may be acquired in a predetermined cycle, or may be acquired at the timing when the voice in step S14 is recognized.

  When the voice data and the position information are transmitted from the receiver terminal 200 to the authentication server 300, voice print authentication is performed by the authentication unit 303 based on the voice data (step S16).

  The specific process of step S16 is the same as the process of step S6 in the first embodiment.

  Subsequently, the visitor terminal (in this case, the visitor terminal 100) that has transmitted the identification information associated with the searched voice data is used by the visitor terminal (in this case, the visitor terminal 100). It is determined by the range determination unit 305 whether or not it exists within a preset distance range from the terminal 200 for the attendee (step S17). This is the location information of the visitor terminal 100 transmitted from the visitor terminal 100 in step S12, and the location information of the visitor terminal 200 transmitted from the responder terminal 200 in step S15. Is determined based on

  In step S17, when the range determination unit 305 determines that the visitor terminal 100 is within the preset distance range from the responder terminal 200, the visitor information associated with the searched voice data is displayed. The data is read from the database 301 by the transmission unit 304 and transmitted to the client terminal 200 (step S18).

  When the visitor information is transmitted from the authentication server 300 to the receiver terminal 200, the visitor information is displayed on the display unit 203 of the receiver terminal 200 (step S19).

  Thereafter, the permission information set in step S13 to “permitted” stored in the database 301 is set to “not permitted” by the reference permission setting unit 302 (step S20). As described above, the timing of setting “No” may be after a predetermined time has elapsed after the permission information becomes “Yes”, or may be set in advance from the visitor terminal 100. This timing may be the timing at which this signal is transmitted, and is not particularly defined here.

  Note that the processing of the authentication server 300 described above may be performed by a logic circuit manufactured according to the purpose.
