The functional components of the door phone slave unit 11 include an audio input / output unit 111 and a video input / output unit 112. The voice input / output unit 111 transmits the voice signal of the visitor collected by the microphone 114 to the doorphone master unit 12, receives the voice signal output from the doorphone master unit 12, and outputs it to the speaker 115. In addition, the video input / output unit 112 transmits a video signal of a visitor photographed by the camera 113 to the intercom base unit 12.

  The door phone device 13 is a server system (or a collection of server systems) that performs control for realizing communication between the communication terminal 20 and the door phone slave unit 11. As functional components of the door phone device 13, an audio input / output unit 131, a video input / output unit 132, a reception unit (reception unit) 133, an authentication unit (authentication unit) 134, and a communication unit (communication unit) 135 are provided. A face information storage unit 136, a communication destination information storage unit 137, and an address information storage unit 138.

  The voice input / output unit 131 is a part that transmits and receives voice signals to and from the door phone slave unit 11. Specifically, the voice input / output unit 131 receives a visitor's voice signal output from the doorphone slave unit 11 via the doorphone master unit 12 and the communication terminal received via the communication network 30. 20 audio signals are transmitted to the doorphone master unit 12. The voice input / output unit 131 outputs the received voice signal of the visitor to the communication unit 135.

  The video input / output unit 132 is a part that receives a video signal from the door phone slave unit 11. Specifically, the video input / output unit 132 receives a video signal of a visitor output from the doorphone slave unit 11 via the doorphone master unit 12. In addition, the video input / output unit 132 outputs a video signal of the visitor to the reception unit 133 and the communication unit 135.

  The receiving unit 133 is a part that receives a video signal that is biometric information of a visitor from the doorphone slave unit 11 via the video input / output unit 132. The visitor's biometric information includes a visitor's face image, fingerprint image, palm print image, retina image, iris image, etc., but the face image is preferably used in that the configuration of the doorphone slave unit 11 is simple and obtainable. It is done. In addition, the reception unit 133 converts the received video signal into authentication data having a predetermined data format, and outputs the authentication data to the authentication unit 134. Note that the conversion of the data format of the video signal may be performed in the doorphone slave unit 11 or the doorphone master unit 12.

  The authentication unit 134 is a part that authenticates a visitor using the authentication data output from the reception unit 133. Specifically, the authentication unit 134 performs authentication processing with reference to matching information stored in advance in the face information storage unit 136. The face information storage unit 136 stores matching information, which is data that characterizes the person to be authenticated, and person-to-be-authenticated person specifying information for specifying the person to be authenticated. For example, as the matching information, data representing facial features such as eyes, nose, mouth, contour, data representing iris patterns, retinal patterns, and the like are used. Further, as the person-to-be-authenticated person specifying information, “Mr. A” that specifies the person characterized by the matching information can be cited.

  The authentication unit 134 extracts feature data necessary for the authentication process from the authentication data, performs a predetermined calculation on the feature data, and collates the feature data with the matching information. When it is determined that the feature data and the matching information match by this collation, the authentication unit 134 outputs the authentication result information “success” and the authentication target identification information corresponding to the matching information to the communication unit 135. To do. On the other hand, if the authentication unit 134 determines that the feature data and all the matching information stored in the face information storage unit 136 do not match, the authentication unit 134 outputs authentication result information “failure” to the communication unit 135.

  The communication unit 135 is a part that requests connection to a specific communication terminal based on the authentication result by the authentication unit 134. More specifically, when the authentication result information is “successful”, the communication unit 135 refers to the communication destination information storage unit 137 and acquires a communication destination telephone number that identifies the communication terminal of the connection destination. This communication destination telephone number is registered in advance corresponding to the authentication-subjected person identification information that is the authentication result of the authenticator. FIG. 2 is a configuration diagram illustrating an example of data stored in the communication destination information storage unit 137. As shown in the figure, in the communication destination information storage unit 137, a communication destination telephone number for specifying a connection destination communication terminal is stored in association with the authenticated person identification information. For example, when the authenticated person identification information is “Mr. A”, the communication unit 135 uses the telephone number “090-5XXX” of the communication terminal 20 that is the communication destination telephone number corresponding to the authenticated person identification information “Mr. A”. -1234 ". Note that if there is no communication destination telephone number corresponding to the authentication-subjected user identification information, the communication unit 135 stops the subsequent processing.

  Returning to FIG. 1, the communication unit 135 also converts the person-to-be-authenticated person identification information into the destination subaddress. This conversion is performed based on a conversion table stored in the address information storage unit 138. FIG. 3 is a configuration diagram illustrating an example of the conversion table stored in the address information storage unit 138. As shown in the figure, the person-to-be-authenticated person identification information “Mr. A” and the destination subaddress “10” are stored in association with each other. When the authentication target specifying information for specifying the visitor authenticated by the authentication unit 134 is “Mr. A”, the communication unit 135 refers to this conversion table and converts it to the destination subaddress “10”.

  Then, the communication unit 135 designates the communication destination telephone number acquired as described above as a destination address, and transmits a connection request signal to the communication network 30. Here, the communication unit 135 transmits a destination subaddress (visitor specifying information) for specifying the visitor authenticated by the authentication unit 134 to the communication terminal 20 together with the transmission of the connection request signal. The destination subaddress is transmitted by adding the destination subaddress “10” to the telephone number “090-5XXX-1234” of the communication terminal 20 included in the connection request signal.

  Further, when receiving a response signal from the communication terminal 20, the communication unit 135 connects to the communication terminal 20 and relays an audio signal and a video signal between the door phone slave unit 11 and the communication terminal 20. Specifically, the communication unit 135 transmits the audio signal transmitted from the door phone slave unit 11 via the audio input / output unit 131 to the communication terminal 20, and the audio signal transmitted from the communication terminal 20 is converted to the audio signal.

Upon receiving the authentication data from the receiving unit 133, the authenticating unit 134 acquires all matching information stored in the face information storage unit 136 (step S03). After that, the authentication unit 134 extracts feature data of a part necessary for authentication from the authentication data, and authenticates the visitor by sequentially comparing the feature data and matching information (step S04).

  When the communication unit 135 receives the authentication result information and the person-to-be-authenticated person identification information as the authentication result from the authentication unit 134, the communication unit 135 determines whether or not the authentication result information is “success” (step S05). If the authentication result information output from the authentication unit 134 is “success” (step S05; YES), the communication destination information storage unit 137 is referred to based on the authentication target person identification information, and the communication destination telephone number is set. Obtain (step S06). Further, the communication unit 135 converts the person-to-be-authenticated person identification information into the called sub address based on the conversion table stored in the address information storage unit 138 (step S07). Further, after adding the destination subaddress converted as described above to the destination address that is the acquired communication destination telephone number, the communication unit 135 transmits a connection request signal including the destination address and the destination subaddress to the communication network 30. (Step S08).

  On the other hand, when a connection request signal is received by the communication terminal 20 via the communication network 30, an incoming call display such as an image or a character corresponding to the destination subaddress is output to the display of the communication terminal 20 (step S09). . Thereafter, the communication terminal 20 waits for a response operation such as pressing of the incoming call button by the user (step S10). When the response operation is accepted in the communication terminal 20, a connection response signal is returned from the communication terminal 20 to the communication unit 135 (step S11).

  And the communication part 135 relays the audio | voice signal and video signal between the door phone subunit | mobile_unit 11 and the communication terminal 20 after receiving a connection response signal from the communication terminal 20 (step S12). Thereby, the bidirectional | two-way audio | voice communication between the doorphone subunit | mobile_unit 11 and the communication terminal 20 and the video communication from the doorphone subunit | mobile_unit 11 to the communication terminal 20 are implement | achieved.

  Hereinafter, the effect of the door phone system 10 which is 1st Embodiment of this invention is demonstrated.

  According to the door phone system 10 configured as described above, biometric information such as a visitor's face image is received, and the biometric information and matching information characterizing the person to be authenticated are collated to authenticate the visitor. The connection request signal is transmitted to the communication terminal 20 based on the authentication result. Thereby, while specifying a visitor rapidly, generation | occurrence | production of the data communication for the visitor identification in the communication terminal 20, and generation | occurrence | production of unnecessary communication traffic with a visitor are suppressed.

  Further, since connection is requested from the communication unit 135 to the communication terminal 20 only when the authentication is successful, generation of useless communication traffic can be further suppressed.

  Further, since the user of the communication terminal 20 can respond to the connection request after referring to the incoming call display and confirming the visitor, unnecessary communication traffic is suppressed, and a visitor having a high necessity for dialogue is provided. A quicker response to is possible.

  Furthermore, since the communication unit 135 requires connection to a communication terminal registered in advance according to the visitor authentication result, for example, connection to a different communication terminal depending on the success or failure of the authentication, the visitor specifying result, etc. And flexible response to visitors.

[Second Embodiment]
A door phone system according to a second embodiment of the present invention will be described below. In addition, the same code | symbol is attached | subjected about the component which is the same as that of 1st Embodiment, or equivalent, and the description is abbreviate | omitted.

  FIG. 5 is a schematic configuration diagram of a door phone system 210 showing a second embodiment of the present invention. The main difference between the door phone system 210 and the door phone system 10 according to the first embodiment described above is that the visitor authentication is performed based on the voice of the visitor, and the door phone system 10 regardless of the success or failure of the authentication. The connection is requested from the communication terminal to the communication terminal. Hereinafter, only the difference of the door phone device 213 having components different from those of the door phone system 10 will be described.

  When the voice input / output unit 231 receives a visitor's voice signal from the door phone slave unit 11, the voice input / output unit 231 outputs the voice signal to the reception unit 233 and the communication unit 235. In addition, when the video input / output unit 232 receives a video signal of a visitor from the doorphone slave unit 11, the video input / output unit 232 outputs the video signal to the communication unit 235.

  The receiving unit 233 receives an audio signal, which is biometric information of a visitor, from the door phone slave unit 11 via the audio input / output unit 231.

Processes of S206 will be described.

  When the door phone slave unit 11 accepts the pressing of the push button by the visitor, it collects the voice of the visitor by the microphone 114 and transmits the voice signal to the door phone device 213 (step S201).

  The receiving unit 233 of the door phone device 213 receives the visitor's voice signal via the door phone master unit 12 and the voice input / output unit 231 and converts it into authentication data in a predetermined data format (step S202). When the authentication unit 234 receives the authentication data from the reception unit 233, the authentication unit 234 acquires all matching information stored in the voice information storage unit 236 (step S203). Thereafter, the authentication unit 234 performs a predetermined calculation on the authentication data, and then authenticates the visitor by sequentially comparing the calculation result with the matching information (step S204).

  The communication unit 235 refers to the communication destination information storage unit 237 based on the authentication result information and the person-to-be-authenticated person identification information, and acquires a communication destination telephone number (step S205). Further, the communication unit 235 converts the combination of the authentication result information as the authentication result and the person-to-be-authenticated person identification information into the destination subaddress based on the conversion table stored in the address information storage unit 238 (step S206).

  Also by the door phone system 210 described above, the voice data of the visitor is received, and the visitor is authenticated by collating the voice data with matching information characterizing the person to be authenticated, and connected to the communication terminal 20 after the authentication. A request signal is transmitted. Thereby, while specifying a visitor quickly, generation | occurrence | production of the data communication for the visitor specification in the communication terminal 20 is suppressed.

  Further, the communication unit 235 transmits information related to the visitor authentication result together with the connection request signal for the communication terminal 20. With such a configuration, since the user of the communication terminal 20 can respond to the connection request after confirming the authentication result, unnecessary communication traffic is suppressed.

  In addition, this invention is not limited to embodiment mentioned above. For example, in the door phone systems 10 and 210, authentication is performed based on a video signal or audio signal of a visitor, but this is not limited to a specific authentication method. For example, authentication may be performed by password authentication using a push button or the like of the door phone slave unit 11, or fingerprint authentication or palm print authentication based on a visitor's fingerprint image or palm print image may be performed.

  In the intercom systems 10 and 210, the destination subaddress is determined based on the person-to-be-authenticated identification information. However, the destination subaddress may be determined based only on the success or failure of the authentication.
