[0028] Next, embodiments of the present invention will be described with reference to the drawings. The present invention is not limited to the following embodiments. In the following drawings, the same parts are denoted by the same reference numerals. Furthermore, the descriptions of the embodiments can be mutually incorporated unless otherwise specified, and the configurations of the embodiments can be combined unless otherwise specified.

[0029] [Embodiment 1] 1 is a block diagram showing an example of the configuration of a visitor identity verification device 10 of this embodiment. As shown in FIG. 1, the device 10 includes a matching target information acquisition unit 11, a master information extraction unit 12, an identity verification unit 13, and No. 1 The device 10 includes an output unit 14. The device 10 may further include a notification unit 15 as an optional configuration. The above-mentioned units are connected to each other by, for example, an internal bus.

[0030] The device 10 may be, for example, a single device including the above-described units, or a device in which the units can be connected via a communication network. The device 10 can also be connected to an external device (described later) via the communication network. The communication network is not particularly limited and any known network can be used, for example, a wired or wireless network. Examples of the communication network include the Internet, the World Wide Web (WWW), a telephone line, a Local Area Network (LAN), a Storage Area Network (SAN), a Delay Tolerant Networking (DTN), a Low Power Wide Area Network (LPWA), and a Local 5G (L5G). Examples of wireless communication include Wi-Fi (registered trademark), Bluetooth (registered trademark), Local 5G, and LPWA. Examples of the wireless communication include direct communication between devices (Ad Hoc communication), infrastructure communication, and indirect communication via an access point. The device 10 may be incorporated into a server as a system. The device 10 may be, for example, a personal computer (PC, for example, desktop or notebook type) on which the program of the present invention is installed, a smartphone, a tablet terminal, a wearable terminal, etc. Furthermore, the device 10 may be in the form of cloud computing or edge computing, for example, in which at least one of the units is located on a server and the other units are located on a terminal.

[0031] 2 shows an example of a block diagram of the hardware configuration of the device 10. The device 10 may include, for example, a central processing unit (CPU, GPU, etc.) 101, a memory 102, a bus 103, a storage device 104, an input device 105, an output device 106, a communication device 107, etc. Note that these are merely examples, and the hardware configuration of the device 10 is not limited to these as long as it is capable of executing each of the above-mentioned units. Each unit of the hardware configuration of the device 10 is connected to each other via a bus 103 and each interface (I / F).

[0032] The central processing unit 101 is responsible for overall control of the device 10. In the device 10, the central processing unit 101 executes, for example, the program of the present invention and other programs, and also reads and writes various information. Specifically, for example, the central processing unit 101 controls a matching target information acquisition unit 11, a master information extraction unit 12, an identity verification unit 13, No. 1 It functions as an output unit 14 and a notification unit 15.

[0033] The bus 103 can also be connected to, for example, an external device. Examples of the external device include an external storage device (such as an external database), an external input device, and an external output device (such as an external display device or an external printer). The device 10 can be connected to an external network (the communication line network) by, for example, a communication device 107 connected to the bus 103, and can also be connected to other devices via the external network.

[0034] The memory 102 may be, for example, a main memory (primary storage device). When the central processing unit 101 performs processing, the memory 102 reads various operating programs, such as the program of the present invention, stored in the storage device 104 (described later), and the central processing unit 101 receives data from the memory 102 and executes the programs. The main memory may be, for example, a RAM (random access memory). Alternatively, the memory 102 may be, for example, a ROM (read only memory).

[0035] The storage device 104 is also referred to as an auxiliary storage device, for example, in contrast to the main memory (primary storage device). As described above, the storage device 104 stores an operating program including the program of the present invention. The storage device 104 may be, for example, a combination of a recording medium and a drive that reads and writes data from and to the recording medium. The recording medium is not particularly limited and may be, for example, an internal or external type, such as a hard disk (HD), CD-ROM, CD-R, CD-RW, MO, DVD, flash memory, or memory card. The storage device 104 may be, for example, a hard disk drive (HDD) or a solid state drive (SSD) in which the recording medium and drive are integrated.

[0036] In the present device 10, the memory 102 and the storage device 104 can also store various information such as log information, information acquired from an external database (not shown) or an external device, information generated by each process of the present device 10, and information used when the present device 10 executes each process. Note that at least a portion of the information may be stored, for example, in an external server other than the memory 102 and the storage device 104, or may be stored in a distributed manner across multiple terminals using blockchain technology or the like.

[0037] The device 10 may further include, for example, an input device 105 and an output device 106. Examples of the input device 105 include an input device for inputting characters, numbers, and position information, such as a digitizer (touch panel, etc.), a keyboard, or a mouse; an input device for inputting images, such as a scanner or an imaging device (camera); or an input device for inputting sound, such as a voice recognition device. Examples of the output device 106 include a display device (LED display, LCD display, etc.), a printer, a speaker, etc.

[0038] Next, an example of the visitor identity verification method of this embodiment will be described with reference to the flowchart of Fig. 3. The visitor identity verification method of this embodiment is implemented, for example, using visitor identity verification device 10 of Fig. 1 as follows. Note that the visitor identity verification method of this embodiment is not limited to use of visitor identity verification device 10 of Fig. 1. Furthermore, the steps in parentheses in Fig. 3 are optional steps.

[0039] In the following description, the matching target information acquisition step can be performed by, for example, a matching target information acquisition unit 11, the master information extraction step can be performed by, for example, a master information extraction unit 12, the identity confirmation step can be performed by, for example, an identity confirmation unit 13, and No. 1 The output process may include, for example, No. 1 The output unit 14 can execute this, and the notification step can be executed by the notification unit 15, for example.

[0040] First, the verification target information acquisition unit 11 acquires verification target information related to a visitor from a handset of an intercom device as a request for verifying the identity of the visitor (S11a). The intercom device is not particularly limited and may include a base unit for responding to calls from visitors and a handset for calling the visited person (staying person), as long as the base unit and the handset are connectable. The request may be output from the handset after a communication path between the handset and the base unit is established, or may be output from the handset before the communication path is established. The communication path between the handset and the base unit is established, for example, when the visitor operates the handset and presses a call button or a room number. On the other hand, a communication path between the handset and the base unit may be established when the identity of the visitor is verified by the identity verification unit 13 (described later). The device 10 and the handset and / or the base unit may be connected in advance via the communication network.

[0041] The matching target information includes biometric information of the visitor. The biometric information is not particularly limited and may be, for example, information such as a face image, fingerprints, irises, bone structure, and voice, and any two or more of these may be used as the biometric information. The matching target information is, for example, information detected by the slave unit and output from the slave unit. The matching target information acquisition unit 11 may, for example, acquire the matching target information directly from the slave unit, or may acquire it indirectly via a database or another device (such as a server).

[0042] Next, the master information extraction unit 12 extracts master information related to the registrant (S12). For example, when the master information extraction unit 12 acquires the matching target information, the master information extraction unit 12 extracts the master information. For example, the master information extraction unit 12 may extract the master information from the storage device 104, or may extract the master information from an external storage device or database. That is, the master information may be stored in advance in the storage device 104, or may be stored in an external storage device or database.

[0043] The master information includes biometric information of the registrant. The biometric information is, for example, the same as described above. Note that the type (e.g., facial image) of the biometric information in the matching target information acquired by the matching target information acquisition unit 11 and the type (e.g., facial image) of the biometric information in the master information extracted by the master information extraction unit 12 may or may not match. The match may be a complete match or a partial match. If the type of biometric information does not match, for example, the identity verification unit 13 described below determines that the visitor is not the registrant (this may also be considered identity verification failure, authentication failure, etc.).

[0044] Next, the identity verification unit 13 verifies the matching target information with the master information to verify the identity of the visitor (S13). Specifically, the identity verification unit 13 verifies at least the biometric information of the matching target information with the biometric information of the master information. Then, for example, if the matching results in a partial or complete match between the biometric information, the identity verification unit 13 authenticates the visitor as the registrant (this is also referred to as successful identity verification or successful authentication). On the other hand, for example, if the matching results in a mismatch or complete mismatch between at least one piece of biometric information, the identity verification unit 13 determines that the identity verification has failed. Furthermore, for example, the identity verification unit 13 may also determine that the identity verification has failed if the matching target information cannot be acquired. For example, the identity verification unit 13 may perform the matching again on the matching target information for which the identity verification has failed. Then, if the re-matching results in a partial or complete match between the biometric information, the identity verification may be determined to have succeeded.

[0045] and, No. 1 The output unit 14 outputs the result of the identity verification to at least one of the slave device and the master device as a response to the request (S14), and the process ends (END). No. 1 The output unit 14 may output the response using a communication path established in advance between the device 10 and the child device and / or the parent device. If the request is output from the child device after the communication path between the child device and the parent device is established, No. 1 The output unit 14 may, for example, output the response only to the child device. The response output to the child device may, for example, be output to the parent device via the communication path. In this way, by outputting the response to the parent device using the communication path that has already been established, the processing load on the device 10 can be reduced. On the other hand, for example, if the request is output from the child device before the communication path between the child device and the parent device is established, No. 1 The output unit 14 may output the response to both the slave device and the master device. No. 1For example, the output unit 14 may output the response only to the child device or only to the parent device. No. 1 The output unit 14 performs the output using, for example, an output device 106 .

[0046] The identity verification unit 13 may, for example, control the connection of the communication path between the slave unit and the master unit depending on the result of the identity verification. Specifically, for example, when the identity of the visitor can be verified (when identity verification is successful), the identity verification unit 13 may establish a communication path between the slave unit and the master unit. On the other hand, for example, when the identity of the visitor cannot be verified (when identity verification is unsuccessful), the identity verification unit 13 may not establish a communication path between the slave unit and the master unit or may cut off an already established communication path. This makes it possible to control the master unit not to respond when a suspicious person visits, for example, thereby reducing the inconvenience and anxiety of the visitor.

[0047] The matching target information acquisition unit 11 may further acquire, for example, visiting destination information (S11b). The step (S11b) may be executed in parallel with the step (S11a), or may be executed at any time before the step (S14). The visiting destination information may be information that is pre-stored in the slave unit, or may be information that can be acquired by the slave unit through an operation by the visitor. Specifically, the information is information that allows the device 10 to identify the visiting destination of the visitor, such as, for example, the identification information of the slave unit, the identification information of the master unit corresponding to the slave unit, and the room number entered into the slave unit. Then, when the visiting destination information is acquired, No. 1 The output unit 14 may output the result of the identity verification to at least one of the slave device and the master device corresponding to the visited destination information. No. 1 The output unit 14 outputs the result of the identity verification to the slave device having the identification information. In this way, by acquiring the visit destination information, it is possible to newly specify the output destination of the response.

[0048] The verification target information and the master information may further include attribute information of the visitor or the registrant. The visitor's attribute information may include, for example, affiliation information (company ID (identifier), employee ID, etc.), name, gender, age, etc. The types of attribute information in the verification target information and the master information may or may not match. The match may be a complete match or a partial match. When acquiring the visitor's attribute information, the master information extraction unit 12 may, for example, identify and extract corresponding master information from multiple pieces of master information based on the attribute information. Multiple pieces of master information may be identified. That is, the master information extraction unit 12 may narrow down the master information. This makes it easy to search for the corresponding master information from multiple pieces of master information. Furthermore, since only the master information to be used for verification can be extracted in this way, the processing speed of the verification can be improved. Furthermore, if the master information cannot be identified, the identity verification unit 13 may, for example, deem identity verification unsuccessful.

[0049] Furthermore, if the visitor's attribute information is included, the identity verification unit 13 may, for example, perform a check based on the biometric information and a check based on the attribute information. The order of the checks is not particularly limited. For example, if at least one of the checks fails, the identity verification unit 13 determines that the identity verification has failed. By performing such multi-stage checks, the legitimacy of the visitor's identity verification result can be further increased.

[0050] If the identity verification unit 13 fails to verify the identity, No. 1 The output unit 14 may output the matching target information to a storage device (for example, the storage device 104, an external storage device, a database, etc.). No. 1 The output unit 14 may, for example, output the date and time information and the matching target information in association with each other. No. 1The matching target information output by the output unit 14 is stored. On the other hand, even if the identity verification unit 13 succeeds in the identity verification, the matching target information may be output to the storage device in the same way as in the case of failure. When the output is performed in both the case of success and the case of failure, for example, the result of the identity verification and the matching target information may be output in association with each other.

[0051] The device 10 may further include, for example, a reporting unit 15. For example, when the identity verification unit 13 fails to verify the identity of the visitor at least twice within a certain period of time, the reporting unit 15 may report the presence of the visitor to a pre-set contact (S15). The contact is not particularly limited, and may be, for example, a housing complex management company, the police, a security company, etc. The reporting method may be, for example, but is not limited to, transmitting information including the verification target information. Furthermore, the reporting unit 15 may report the contact not only when the visitor (resident, etc.) fails to verify the identity twice or more times, but also upon instruction from the visitor (resident, etc.) via the base unit. In this way, the device 10 can report a person who has failed to verify the identity multiple times as a suspicious person to the contact and provide information.

[0052] According to this embodiment, the visitor's biometric information is used to confirm their identity, thereby ensuring the legitimacy of their identity. Furthermore, according to this embodiment, the visitor's identity can be confirmed without the visitor and the visited person meeting face-to-face, ensuring the safety of the visited person even if the visitor is suspicious. Furthermore, in this embodiment, the master information is stored in a storage device that can be accessed from the company to which the visitor belongs, for example, so that the visitor's identity can be confirmed even if the visit is unexpected for the visited person.

In the present embodiment, an apartment building is exemplified as the destination of the waiting person, but this is not limiting.

Unless otherwise specified, the description of the hardware configuration in the first embodiment can be applied to the units in the hardware configuration of the parent device 20 and the child device 30.

[0060] As shown in Fig. 6, in the base unit 20, the central processing unit 101 functions as a notification unit 21 and a response unit 22. As shown in Fig. 7, in the handset 30, the central processing unit 101 functions as a calling unit 31, a detecting unit 32, No. 2It functions as an output unit 33, an acquisition unit 34, and a notification unit 35.

[0061] Next, an example of the base unit side information processing method of this embodiment will be described based on the flowchart of Fig. 8. The base unit side information processing method of this embodiment is implemented as follows, for example, using base unit 20 of Fig. 5. Note that the base unit side information processing method of this embodiment is not limited to use of base unit 20 of Fig. 5. Also, the steps in parentheses in Fig. 8 are optional steps.

[0062] In the following, the notification step can be performed by the notification unit 21, and the response step can be performed by the response unit 22, for example.

[0063] In the base unit-side information processing method of this embodiment, when a communication path with the handset 30 is established, the notification unit 21 notifies the handset 30 that it has been called (S21), and the method ends (END). The establishment of a communication path with the handset 30 can be, for example, when the handset 30 is operated or when the identity of the visitor is confirmed by the identity confirmation unit 13 of the visitor identity verification device 10, as described above. The notification method is not particularly limited, and may include a sound (such as a sound emitted by the base unit 20 or the visitor's voice obtained by the handset 30) or a video captured by the handset 30. For example, in addition to notifying the visitor that the call has been made, the notification unit 21 may obtain the result of the identity verification output from the visitor identity verification device 10 and notify the visitor (visitor, etc.) of the result of the identity verification. The method of notifying the visitor of the result of the identity verification is not particularly limited. For example, the result of the identity verification may be displayed on a display device (output device 106), or a specific sound, a lamp light, or the like may be used.

[0064] If the base unit 20 includes a response unit 22, the response unit 22 enables, for example, the visited person (visitor, etc.) to respond to the call (S22). The method of response is not particularly limited. The response unit 22 enables the response, for example, by enabling a call between the visitor and the waiting person.

[0065] For example, when the visitor identity verification device 10 outputs, together with the notification, that the identity verification has failed, the response unit 22 may ask the visited person whether or not to answer the call. The confirmation may be performed by displaying a message on the display device (output device 106) asking whether or not to answer the call, but is not limited to this. Then, the response unit 22 takes either of two actions, for example, answering the call or not answering the call, according to the visitor's instructions.

[0066] For example, the base unit 20 may be capable of transmitting an instruction to the visitor identity verification device 10 to make the notification in accordance with an instruction from the person visited.

[0067] Next, an example of the slave device side information processing method of this embodiment will be described based on the flowchart of Fig. 9. The slave device side information processing method of this embodiment is implemented as follows, for example, using the slave device 30 of Fig. 5. Note that the slave device side information processing method of this embodiment is not limited to use of the slave device 30 of Fig. 5. Also, the steps in parentheses in Fig. 9 are optional steps.

[0068] In the following, the calling step can be performed by, for example, a calling unit 31, the detecting step can be performed by a detecting unit 32, and No. 2 The output process may include, for example, No. 2 The output unit 33 can perform the process, the acquisition step can be performed by, for example, the acquisition unit 34, and the notification step can be performed by, for example, the notification unit 35.

[0069] In the slave-side information processing method of this embodiment, first, the calling unit 31 executes a process of calling the base unit 20 (S31). The process is not particularly limited, and known techniques can be used. In the process, a communication path with the base unit 30 may be established, or may not be established as described above.

[0070] Next, the detection unit 32 detects information to be matched regarding the visitor (S32). The information to be matched is the same as that described above. The detection may be performed using, for example, an imaging device or various sensors (input device 105). For example, a fingerprint may be detected when the visitor presses a button on the handset 30.

[0071] The order of the steps (S31) and (S32) is not particularly limited, and they may be performed in parallel, or the step (S32) may be performed first.

[0072] and, No. 2 The output unit 33 outputs the matching target information as a request for verifying the identity of the visitor (S33), and the process ends (END). The request may be output, for example, when the calling unit 31 executes a process to call the base unit 20. The request is output, for example, to the visitor identity verification device 10. No. 2 The output unit 33 may output, for example, video and sound input by the input device 105 to the parent device 20. No. 2 The output unit 33 performs the output using, for example, the output device 106 .

[0073] If the handset 30 includes an acquisition unit 34, the acquisition unit 34 may acquire the visited destination information from the visitor, for example. The acquisition unit 34 can acquire the visited destination information (e.g., the room number of the visited destination) by, for example, the visitor pressing a button on the handset 30. Then, the handset 30 establishes a communication path with the base unit 20 based on the visited destination information. However, as described above, the establishment of a communication path between the base unit 20 and the handset 30 is not limited to this.

[0074] When a communication path with the base unit 20 is established and / or when the visited person answers the call, the calling unit 31 may enable, for example, a call between the visiting person and the waiting person. This allows the visitor and the visited person to converse with each other via the base unit 20 and the handset 30.

[0075] If the slave unit 30 includes an acquisition unit 34 and a notification unit 35, the acquisition unit 34 may, for example, acquire the result of the identity verification output from the visitor identity verification device 10 after the step (S33) (S34). Then, the notification unit 35 may, for example, notify the visitor of the result of the identity verification (S35). The method of notifying the result of the identity verification is not particularly limited and is the same as described above. The notification unit 35 may, for example, notify the master unit 20 of the result of the identity verification.

[0076] (Interphone system device 100) The intercom system device 100 and the visitor identity verification method using the intercom system device 100 will be described in more detail with reference to FIG. 4, but this is merely an example and the present invention is not limited thereto.

[0077] The company terminal 50 registers the biometric information and attribute information of employees in advance in the database 40 as master information ((1) in FIG. 4).

[0078] Visitor A inputs the destination information and attribute information into handset 30 of the intercom device at the visitor's location ((2) in FIG. 4). After that, video and a facial image of visitor A are captured by imaging device 108 of handset 30 ((2) in FIG. 4). Then, the facial image of visitor A and the attribute information are transmitted as a request for identity verification from handset 30 to visitor identity verification device 10 (server) via the communication network ((3) in FIG. 4). Meanwhile, after inputting the destination information, a communication path is established between handset 30 and base unit 30 based on the destination information.

[0079] Based on the attribute information, the visitor identity verification device 10 narrows down the master information in the database 40 to one that matches the attribute information. Then, the visitor identity verification device 10 verifies the master information against the information to be verified and performs identity verification ((4) in FIG. 4). The visitor identity verification device 10 outputs the result of the identity verification to the slave device 30 that sent the request ((3) in FIG. 4).

[0080] The slave device 30 acquires the result of the identity verification and notifies the master device 20 of the result of the identity verification and the video captured by the imaging device (input device 105) via the communication path ((5) in FIG. 4).

[0081] The base unit 20 acquires the identity verification result and the video from the sub-unit 30 and notifies visitor B of these ((6) in FIG. 4). Visitor B checks the identity verification result and decides whether to answer visitor A's call. Visitor B may, for example, instruct visitor identity verification device 10 to make the notification via base unit 20 as necessary (for example, if the identity verification result is unsuccessful). Then, visitor identity verification device 10 notifies the contact person. As a result, a person who receives the notification (for example, security guard C) will be dispatched to the visitor's location.

[0082] According to the intercom system device and visitor identity confirmation method of this embodiment, similarly to the first embodiment, it is possible to confirm the identity of the visitor and ensure the legitimacy of the visitor's identity.

In the present invention, "procedure" may be read as "processing." The program of this embodiment may be recorded, for example, on a computer-readable recording medium. The recording medium is, for example, a non-transitory computer-readable storage medium. The recording medium is not particularly limited, and examples thereof include a read-only memory (ROM), a hard disk (HD), an optical disk, etc.
