The information output system, authentication system, terminal system, information output method, and program according to the first to third embodiments will be described below with reference to the drawings. Figures 1 to 6 referred to in the following first to third embodiments are all schematic diagrams, and the ratios of sizes and thicknesses of the components in the figures do not necessarily reflect the actual dimensional ratios.

(Embodiment 1)
(1) Overview First, an overview of an information output system 3, an authentication system 9, a terminal system 1, an information output method, and a program according to the first embodiment will be described with reference to FIG.

As shown in FIG. 1, the information output system 3 and terminal system 1 according to the first embodiment are used in an intercom system 10 together with multiple (two in the illustrated example) intercom master units 2. That is, the intercom system 10 according to the first embodiment includes the terminal system 1, multiple intercom master units 2, and the information output system 3.

In the apartment complex intercom system described in Patent Document 1 above, when a room number is entered to call a room, facial recognition is performed using a facial image registered in association with the room number, with the aim of improving security. However, the apartment complex intercom system described in Patent Document 1 is premised on measures against burglaries in which unauthorized calls are made multiple times, and facial recognition is performed after the room number is entered and the call is answered. Therefore, while security is improved, there is a problem of reduced convenience.

Therefore, the information output system 3 and the terminal system 1 according to the first embodiment can suppress a decrease in convenience while maintaining the security of the intercom system 10 by adopting the following configuration.

That is, the information output system 3 according to the first embodiment includes a first acquisition unit 311, a second acquisition unit 312, and an output unit 313. The first acquisition unit 311 acquires first information input to an input unit 15 provided in a first area 71, which is a shared area of the collective facility 7. The second acquisition unit 312 acquires second information related to an image captured by an imaging unit 13, which includes at least a part of the first area 71 in its imaging range. The output unit 313 outputs third information based on an authentication result of the second information for the authentication information associated with the first information. The first information includes information for identifying the second area 72, which is an exclusive area of the collective facility 7. The second information includes image information of visitors to the collective facility 7.

The terminal system 1 according to the first embodiment is a terminal system provided in the first area 71, which is a shared area of the collective facility 7. The terminal system 1 includes an input unit 15, an imaging unit 13, and an output unit 111. The input unit 15 accepts input of specific information for identifying the second area 72, which is an exclusive area of the collective facility 7. The imaging unit 13 captures a specific image including a visitor. The output unit 111 outputs authentication information used for authentication based on the specific image. In the terminal system 1, when the input unit 15 accepts input of specific information, at least one of an imaging process in which the imaging unit 13 captures a specific image and an output process in which the output unit 111 outputs authentication information is executed.

The terminal system 1 according to the first embodiment is a terminal system provided in the first area 71, which is a shared area of the collective facility 7. The terminal system 1 includes an input unit 15, an imaging unit 13, and a notification unit 112. The input unit 15 accepts input of specific information for identifying the second area 72, which is an exclusive area of the collective facility 7. The imaging unit 13 captures a specific image including a visitor. When the input unit 15 accepts input of specific information, the notification unit 112 notifies at least one of the fact that the imaging unit 13 will capture a specific image and that the visitor will be authenticated based on the specific image.

According to the above configuration, the second information is authenticated using the authentication information associated with the first information (specific information) input to the input unit 15. This makes it possible to improve security compared to the case where the second information is authenticated using all authentication information. In addition, since the second information can be authenticated simply by inputting information (specific information) for identifying the second area 72 to the input unit 15, it is also possible to suppress a decrease in convenience. In other words, according to the information output system 3 and the terminal system 1 of the first embodiment, it is possible to suppress a decrease in convenience while maintaining security. Furthermore, since it is only necessary to compare the authentication information associated with the first information with the second information, it is also possible to shorten the time required to authenticate the second information.

The information output system 3 according to the first embodiment, together with the authentication unit 314, constitutes an authentication system 9. That is, the authentication system 9 according to the first embodiment includes the information output system 3 and the authentication unit 314. The authentication unit 314 executes authentication of the second information against the authentication information. According to such an authentication system 9, it is possible to suppress a decrease in convenience while maintaining security.

The information output system 3 according to the first embodiment is one aspect that embodies the information output method according to the first embodiment. That is, the information output method according to the first embodiment has a first acquisition step, a second acquisition step, and an output step. In the first acquisition step, first information input to the input unit 15 provided in the first area 71, which is a common area of the collective facility 7, is acquired. In the second acquisition step, second information regarding an image captured by the imaging unit 13, which includes at least a part of the first area 71 in its imaging range, is acquired. In the output step, third information based on the authentication result of the second information for the authentication information associated with the first information is output. The first information includes information for identifying the second area 72, which is an exclusive area of the collective facility 7. The second information includes image information of visitors to the collective facility 7. According to such an information output method, it is possible to suppress a decrease in convenience while maintaining security.

The information output method according to the first embodiment can be embodied by a program. That is, the program according to the first embodiment is a program for causing one or more processors to execute the information output method according to the first embodiment. Such a program makes it possible to suppress a decrease in convenience while maintaining security.

In this disclosure, the term "collective facility" refers to a structure that is a collection of multiple facilities and includes multiple facilities within one building. In this disclosure, the term "facility" refers to residential facilities used for residential purposes, as well as non-residential facilities such as stores (tenants), offices, welfare facilities, educational facilities, hospitals, and factories. Non-residential facilities also include restaurants, amusement parks, hotels, inns, kindergartens, nurseries, and community centers. In other words, the collective facility 7 may be a collective housing complex such as an apartment building, or a non-residential facility such as an office building. Furthermore, the collective facility 7 also includes facilities in which residential facilities and non-residential facilities are mixed, such as stores on the lower floors and residences on the upper floors. In this embodiment, as an example, it is assumed that the collective facility 7 is a collective housing complex (such as an apartment building) that includes multiple residences.

(2) Details Next, a detailed configuration of the intercom system 10 including the terminal system 1 and the information output system 3 according to the first embodiment will be described with reference to FIG.

As shown in FIG. 1, the intercom system 10 includes a terminal system 1, multiple (two in the illustrated example) intercom master units 2, and an information output system 3. The intercom system 10 also includes an entrance door 6. The intercom system 10 is installed in a collective facility 7. The collective facility 7 is, for example, a collective housing complex such as an apartment building.

The collective facility 7 includes a first area 71, a plurality of (two in the illustrated example) second areas 72, and a third area 73. The first area 71 is a common area of the collective facility 7, for example, a lobby of an apartment building serving as the collective facility 7. Each of the plurality of second areas 72 is an occupied area of the collective facility 7, for example, each dwelling unit of the apartment building serving as the collective facility 7. The third area 73 is a common area of the collective facility 7, for example, a manager's room of the apartment building serving as the collective facility 7.

(2.1) Terminal System The terminal system 1 is, for example, a lobby intercom (intercom handset) installed in the first area 71 of the collective facility 7. That is, the terminal system 1 is a terminal system provided in the first area 71, which is a shared area of the collective facility 7. The terminal system 1 is connected to the information output system 3 via a first transmission line 41. The first transmission line 41 is, for example, a twisted pair wire, but is represented by a single line in Fig. 1. The same applies to Figs. 3 and 5 described below.

The terminal system 1 includes a control unit 11, a display unit 12, an imaging unit 13, a call unit 14, an input unit 15, a communication unit 16, and a memory unit 17.

The control unit 11 mainly comprises a computer system having one or more processors and one or more memories. In the terminal system 1, the functions of the control unit 11 (including the output unit 111 and the notification unit 112 described below) are realized by the one or more processors executing a program recorded in the memory. The program may be pre-recorded in the memory, may be provided via a telecommunications line such as the Internet, or may be recorded on a non-temporary recording medium such as a memory card and provided. The control unit 11 is configured to control the display unit 12, the imaging unit 13, the call unit 14, and the communication unit 16 separately.

As shown in FIG. 1, the control unit 11 has an output unit 111 and an alarm unit 112.

The output unit 111 outputs authentication information. The authentication information is information used for authentication based on a specific image, and includes, for example, features extracted from a face image. The specific image is an image captured by the imaging unit 13, and is an image that includes a visitor (a visitor or a resident) to the collective facility 7. When the input unit 15 described below receives the specific information, the output unit 111 executes an output process that outputs the authentication information.

The notification unit 112 executes at least one of a first notification process and a second notification process when the input unit 15 described below accepts input of specific information. The first notification process is a process of notifying that the imaging unit 13 will capture a specific image. The second notification process is a process of notifying that the authentication unit 314 of the information output system 3 described below will authenticate the visitor based on the specific image. In this embodiment, the notification unit 112 executes both the first notification process and the second notification process when the input unit 15 accepts specific information, but for example, the notification unit 112 may execute only the first notification process or only the second notification process.

The control unit 11 also executes an extraction process to extract facial features of the visitor from the specific image captured by the imaging unit 13. The control unit 11 then creates second information including the facial features of the visitor. That is, the second information is information about the image (specific image) captured by the imaging unit 13, and includes image information (feature features) of the visitor to the collective facility 7. Furthermore, the control unit 11 reads out corresponding authentication information from the storage unit 17 based on the first information (specific information) input via the operation unit 151 described below. The control unit 11 then creates a communication signal including the first information, the second information, and the authentication information, and causes the communication unit 16 to transmit the created communication signal to the information output system 3.

The display unit 12 includes a display device such as a liquid crystal display or an organic EL (Electro Luminescence) display. The display unit 12 displays, for example, an image of a visitor captured by the imaging unit 13. The display unit 12 also displays a message to the visitor. If the terminal system 1 is equipped with a touch panel display, the touch panel display may function as both the display unit 12 and the input unit 15.

The imaging unit 13 is configured to capture a specific image. The specific image is an image that includes a visitor or the like located in front of the terminal system 1. That is, the imaging range of the imaging unit 13 is set to include at least a part of the first area 71. The imaging unit 13 includes a solid-state imaging element and a lens. The solid-state imaging element is, for example, a two-dimensional image sensor such as a CCD (Charge Coupled Devices) image sensor or a CMOS (Complementary Metal-Oxide Semiconductor) image sensor. The imaging unit 13 outputs an output signal of the solid-state imaging element to the control unit 11 as a video signal. When specific information is input to the input unit 15 described below, the imaging unit 13 executes imaging processing to capture a specific image.

The intercom unit 14 includes a speaker and a microphone. The intercom unit 14 is configured to be able to communicate with the intercom unit 23 of each of the multiple intercom master units 2.

The input unit 15 accepts the input of specific information (first information). The specific information includes information for identifying the second area 72, which is an exclusive portion of the collective facility 7, and includes, for example, a room number assigned to the dwelling unit as the second area 72. The input unit 15 includes an operation unit 151. The operation unit 151 is configured to accept operations by visitors, etc. The operation unit 151 is, for example, an input interface having a plurality of push button switches and a touch panel, etc. In this embodiment, the operation unit 151 has a call button and a confirmation button as the plurality of push button switches. The call button is a button that is operated when calling the second area 72 associated with the specific information after inputting the specific information. The confirmation button is a button that is operated when confirming (registering) the input specific information after inputting the specific information. The visitor inputs the specific information (first information) by performing a predetermined operation on the operation unit 151. That is, the first information includes information (room number) input by the visitor's operation on the operation unit 151.

The communication unit 16 includes a communication interface for communicating with each of the communication units 25 of the multiple intercom master units 2. The communication unit 16 is connected to the transmission processing unit 32 of the information output system 3 via the first transmission path 41. The communication unit 16 transmits communication signals such as audio signals and video signals to each intercom master unit 2 via the information output system 3. Furthermore, the communication unit 16 receives communication signals such as audio signals and control signals from each intercom master unit 2 via the information output system 3. Here, the communication signal from the terminal system 1 includes information (e.g., address information, etc.) for identifying the intercom master unit 2. Therefore, only the intercom master unit 2 to which address information that matches the address information included in this communication signal is assigned can receive the communication signal.

The storage unit 17 is composed of a readable and writable memory such as a flash memory. The storage unit 17 stores, for example, video data of a video (image) captured by the imaging unit 13. The storage unit 17 also stores the above-mentioned authentication information (feature amount of a facial image) and the first information in association with each other. The storage unit 17 may be an internal memory of the control unit 11.

(2.2) Intercom Master Unit Each of the multiple intercom master units 2 is installed in a corresponding one of the multiple second areas 72 in the collective facility 7, for example. Each of the multiple intercom master units 2 is connected to the information output system 3 via a second transmission path 42. The second transmission path 42 is composed of a trunk line 421 and multiple (two in the illustrated example) branch lines 422. The trunk line 421 is connected to the information output system 3. Each of the multiple branch lines 422 is connected to a corresponding one of the multiple intercom master units 2. Each of the multiple branch lines 422 branches off from the trunk line 421. A splitter 5 is provided at each branch point of the multiple branch lines 422. The second transmission path 42 is, for example, a twisted pair line, but is represented by a single line in FIG. 1. The same applies to FIGS. 3 and 5 described below.

Each of the multiple intercom master units 2 includes a control unit 21, a display unit 22, a call unit 23, an operation unit 24, a communication unit 25, and a memory unit 26.

The control unit 21 mainly comprises a computer system having one or more processors and one or more memories. In each intercom master unit 2, the functions of the control unit 21 are realized by one or more processors executing a program recorded in the memory. The program may be pre-recorded in the memory, may be provided via a telecommunications line such as the Internet, or may be recorded and provided on a non-temporary recording medium such as a memory card. The control unit 21 is configured to control the display unit 22, the call unit 23, and the communication unit 25 separately.

The display unit 22 includes a display device such as a liquid crystal display or an organic EL display. The display unit 22 displays, for example, an image of a visitor captured by the imaging unit 13. More specifically, when the intercom master unit 2 is in a state in which it can make a call (communicate) with the terminal system 1, the display unit 22 displays an image of a visitor captured by the imaging unit 13 of the terminal system 1 with which it is to communicate. Note that, when each intercom master unit 2 is equipped with a touch panel display, the touch panel display may function as both the display unit 22 and the operation unit 24.

The communication unit 23 includes a speaker and a microphone. The communication unit 23 is configured to be able to communicate with the communication unit 14 of the terminal system 1.

The operation unit 24 is configured to accept operations from residents of each dwelling unit, etc. The operation unit 24 has at least a call button. The call button is a button for starting communication with the terminal system 1 (a call with a visitor) in response to a call from the terminal system 1. In other words, when the call button is pressed while the communication unit 25 is receiving a call signal to call a resident, a voice call becomes possible between the terminal system 1 and each intercom master unit 2.

The communication unit 25 includes a communication interface for communicating with the communication unit 16 of the terminal system 1. The communication unit 25 is connected to the information output system 3 via the main line 421, the branch line 422, and the splitter 5. The communication unit 25 transmits communication signals such as audio signals and control signals to the terminal system 1 via the information output system 3. Furthermore, the communication unit 25 receives communication signals such as audio signals and video signals from the terminal system 1 via the information output system 3.

The storage unit 26 is composed of a readable and writable memory such as a flash memory. The storage unit 26 stores, for example, video data of the video (image) captured by the imaging unit 13. The storage unit 26 also stores identification information (for example, address information) assigned to the corresponding intercom master unit 2. The storage unit 26 may be an internal memory of the control unit 21.

(2.3) Information Output System The information output system 3 is, for example, a control device installed in the third area 73 of the collective facility 7. The information output system 3 includes a control unit 31, a transmission processing unit 32, and a storage unit 33.

The control unit 31 is mainly composed of a computer system having one or more processors and one or more memories. In the information output system 3, the functions of the control unit 31 (including a first acquisition unit 311, a second acquisition unit 312, an output unit 313, and an authentication unit 314 described below) are realized by one or more processors executing a program recorded in the memory. The program may be pre-recorded in the memory, may be provided via a telecommunications line such as the Internet, or may be recorded on a non-temporary recording medium such as a memory card and provided. The control unit 31 is configured to control the transmission processing unit 32.

As shown in FIG. 1, the control unit 31 has a first acquisition unit 311, a second acquisition unit 312, an output unit 313, and an authentication unit 314.

The first acquisition unit 311 acquires the first information (specific information) input to the input unit 15 of the terminal system 1. As described above, the terminal system 1 is provided in the first area 71, which is the common area of the collective facility 7. That is, the first acquisition unit 311 acquires the first information input to the input unit 15 provided in the first area 71, which is the common area of the collective facility 7. The first information includes information input by a visitor operating the operation unit 151 of the input unit 15, and includes, for example, the room number of the dwelling unit as the second area 72.

The second acquisition unit 312 acquires the second information. The second information is information relating to an image captured by the imaging unit 13, and includes, for example, image information of a visitor to the collective facility 7. More specifically, the second information includes facial features of the visitor extracted from the image (specific image) captured by the imaging unit 13. The second information is used to authenticate the visitor in the authentication unit 314 described below.

The output unit 313 outputs the third information. The third information is information based on the authentication result of the second information against the authentication information. More specifically, the third information includes result information indicating whether or not authentication of the visitor using the second information was successful. As described above, the authentication information is information for comparison with the facial features of the visitor contained in the second information, and is associated with the first information.

The authentication unit 314 performs authentication of the second information against the authentication information. More specifically, the authentication unit 314 compares the features of the face image included in the authentication information with the features of the face of the visitor included in the second information to determine whether the visitor is registered. Here, in this embodiment, as described above, the authentication information and the first information are associated with each other. Therefore, the authentication unit 314 performs authentication of the second information using only the authentication information associated with the first information. Therefore, compared to the case where all the authentication information stored in the storage unit 17 of the terminal system 1 is compared with the second information, it is possible to improve the authentication accuracy and shorten the authentication time. In this embodiment, as described above, the information output system 3 includes the authentication unit 314, and the authentication system 9 is configured by the information output system 3. That is, the authentication system 9 includes the information output system 3 and the authentication unit 314 that performs authentication of the second information against the authentication information.

The transmission processing unit 32 is connected to the communication unit 16 of the terminal system 1 via the first transmission path 41. The transmission processing unit 32 is also connected to the communication units 25 of the multiple intercom master units 2 via the second transmission path 42. The transmission processing unit 32 receives a communication signal transmitted from the communication unit 16. The transmission processing unit 32 then transmits the communication signal to the intercom master unit 2 of the dwelling unit (second area 72) corresponding to the address contained in the received communication signal. The transmission processing unit 32 also receives a communication signal transmitted from the communication unit 25 and transmits the received communication signal to the terminal system 1. In other words, the information output system 3 is a relay system that connects the intercom master unit 2 of the dwelling unit that is called by a visitor to the terminal system 1 and relays communication (calls) between the two.

The memory unit 33 is composed of a readable and writable memory such as a flash memory. For example, the memory unit 33 stores the room numbers assigned to each dwelling unit (second area 72) in association with the address information assigned to each intercom master unit 2. The memory unit 33 may be an internal memory of the control unit 31.

(2.4) Entrance Door The entrance door 6 is provided between a first area 71 and a plurality of second areas 72 in the collective facility 7. That is, the entrance door 6 is a door that separates the lobby as the first area 71 from each dwelling unit as the second area 72. As shown in FIG. 1 , the entrance door 6 has an electric lock 61. The electric lock 61 is electrically connected to the information output system (lobby intercom) 3. This makes it possible for the information output system 3 to control the locking and unlocking of the entrance door 6. That is, if the entrance door 6 is an automatic door, the information output system 3 can control the entrance door 6 to open the entrance door 6, which is in a closed state by default.

(3) Information Output Method Next, details of the information output method according to the first embodiment will be described with reference to Fig. 2. The information output method according to the first embodiment is embodied in the information output system 3, and therefore, hereinafter, the information output method will be described with reference to the operation of the information output system 3. Fig. 2 is a sequence diagram showing an example of the basic operation (information output method) of the information output system 3 according to the first embodiment.

A visitor who visits the collective facility 7 inputs the first information (room number of the residence to be visited) using the operation unit 151 of the input unit 15 of the terminal system 1 (input step S111). In the terminal system 1, when the input unit 15 accepts the input of the first information, the control unit 11 causes the imaging unit 13 to capture a specific image including the visitor (imaging step S112). In this case, it is preferable to cause the notification unit 112 to execute the first notification process before the imaging unit 13 executes the imaging process. In addition, the control unit 11 reads out authentication information associated with the first information from the storage unit 17 based on the first information input to the input unit 15. In addition, the control unit 11 creates second information including the facial features of the visitor from the specific image captured by the imaging unit 13. Then, the control unit 11 creates a communication signal including the first information, the second information, and the authentication information, and causes the communication unit 16 to transmit the created communication signal to the information output system 3 (output step S113).

In the information output system 3, the control unit 31 acquires the first information, the second information, and the authentication information contained in the communication signal from the terminal system 1 (acquisition step S114). More specifically, the first acquisition unit 311 acquires the first information and the authentication information, and the second acquisition unit 312 acquires the second information. Note that the authentication information may be acquired by the second acquisition unit 312. In this embodiment, the acquisition step S114 is the first acquisition step and the second acquisition step in the information output method.

Next, in the information output system 3, the authentication unit 314 of the control unit 31 performs authentication of the visitor using the authentication information and the second information (authentication step S115). More specifically, the authentication unit 314 compares the features of one or more facial images included in the authentication information with the features of the visitor's face included in the second information, and determines that the authentication of the visitor has been successful if the authentication information contains features that match the features of the visitor's face. Also, the authentication unit 314 determines that the authentication of the visitor has failed if the authentication information does not contain features that match the features of the visitor's face. In this case, it is preferable to have the notification unit 112 perform the second notification process before performing the authentication process by the authentication unit 314. Then, the control unit 31 creates a communication signal including the authentication result (third information) of the authentication unit 314, and causes the transmission processing unit 32 to transmit the created communication signal to the terminal system 1 (output step S116). Also, if the authentication of the visitor has been successful, the control unit 31 transmits an unlocking signal to the front door 6 (transmission step S117). Then, at the front door 6, the electric lock 61 is unlocked in accordance with the unlocking signal from the information output system 3 (unlocking step S118). In this embodiment, the output step S116 is the output step in the information output method.

In FIG. 2, the image capturing step S112 is executed after the input step S111, but the input step S111 may be executed after the image capturing step S112. Also, in FIG. 2, the transmission step S117 is executed after the output step S116, but the output step S116 may be executed after the transmission step S117.

(4) Effects In the information output system 3 and the terminal system 1 according to the first embodiment, the second information is authenticated using authentication information associated with the first information (specific information) input to the input unit 15. This makes it possible to improve security compared to the case where the second information is authenticated using all authentication information. In addition, in the information output system 3 and the terminal system 1 according to the first embodiment, the second information can be authenticated by simply inputting information (specific information) for identifying the second area 72 to the input unit 15, so that it is also possible to suppress a decrease in convenience. That is, according to the information output system 3 and the terminal system 1 according to the first embodiment, it is possible to suppress a decrease in convenience while maintaining security.

In addition, in the information output system 3 and terminal system 1 according to the first embodiment, it is only necessary to compare the authentication information associated with the first information with the second information, so that it is possible to reduce the time required to authenticate the second information.

In addition, in the terminal system 1 according to the first embodiment, when specific information (first information) is input to the input unit 15, the notification unit 112 executes the first notification process and the second notification process. This makes it possible to notify the visitor before the imaging process by the imaging unit 13 or the authentication process by the authentication unit 314 is executed.

(5) Modifications The first embodiment is merely one of various embodiments of the present disclosure. Various modifications of the first embodiment are possible depending on the design, etc., as long as the object of the present disclosure can be achieved.

In the imaging step S112, a specific image including a visitor is captured. In the output step S113, authentication information used for authentication based on the specific image is output. In the control method of the terminal system 1, when input of specific information is accepted in the input step S111, at least one of the imaging step S112 of capturing a specific image and the output step S113 of outputting authentication information is executed. According to such a control method of the terminal system 1, it is possible to suppress a decrease in convenience while maintaining security.

In addition, a control method for a terminal system 1 according to one embodiment is a control method for a terminal system 1 provided in a first area 71, which is a shared area of a collective facility 7. The control method for the terminal system 1 includes an input step S111, an imaging step S112, and a notification step. In the input step S111, input of specific information (first information) for identifying a second area 72, which is an exclusive area of the collective facility 7, is accepted. In the imaging step S112, a specific image including a visitor is captured.

According to such a control method for a terminal system 1, it is possible to suppress a decrease in convenience while maintaining security.

In addition, one embodiment of the program is a program for causing one or more processors to execute the control method of the terminal system 1. Such a program makes it possible to suppress a decrease in convenience while maintaining security.

Below, we list some variations of the first embodiment. The variations described below can be combined as appropriate.

The terminal system 1, the intercom master unit 2, and the information output system 3 (authentication system 9) in the present disclosure include, for example, a computer system. The computer system is mainly composed of a processor and a memory as hardware. The processor executes a program recorded in the memory of the computer system to realize the functions of the terminal system 1, the intercom master unit 2, or the information output system 3 (authentication system 9) in the present disclosure. The program may be pre-recorded in the memory of the computer system, may be provided through a telecommunication line, or may be recorded and provided in a non-transitory recording medium such as a memory card, an optical disk, or a hard disk drive that can be read by the computer system. The processor of the computer system is composed of one or more electronic circuits including a semiconductor integrated circuit (IC) or a large-scale integrated circuit (LSI). The integrated circuits such as IC or LSI referred to here are called different names depending on the degree of integration, and include integrated circuits called system LSI, VLSI (Very Large Scale Integration), or ULSI (Ultra Large Scale Integration). Furthermore, a field-programmable gate array (FPGA) that is programmed after the manufacture of the LSI, or a logic device that allows reconfiguration of the connection relationship within the LSI or reconfiguration of the circuit partition within the LSI, can also be used as a processor. The electronic circuits may be integrated into one chip, or may be distributed among multiple chips. The chips may be integrated into one device, or may be distributed among multiple devices. The computer system referred to here includes a microcontroller having one or more processors and one or more memories. Therefore, the microcontroller is also composed of one or more electronic circuits including a semiconductor integrated circuit or a large-scale integrated circuit.

Furthermore, it is not essential that the multiple functions of the terminal system 1, the intercom master unit 2, or the information output system 3 (authentication system 9) are concentrated in one housing. The components of the terminal system 1, the intercom master unit 2, or the information output system 3 (authentication system 9) may be distributed across multiple housings. Furthermore, at least some of the functions of the terminal system 1, the intercom master unit 2, or the information output system 3 (authentication system 9) may be realized by the cloud (cloud computing), etc.

Conversely, in embodiment 1, at least some of the functions of the terminal system 1, the intercom master unit 2, or the information output system 3 (authentication system 9), which are distributed among multiple devices, may be consolidated within one housing. For example, some of the functions distributed among the terminal system 1 and the information output system 3 (authentication system 9) may be consolidated into the terminal system 1.

In the first embodiment, the first acquisition unit 311 acquires the first information by inputting the first information into the input unit 15. However, for example, the first acquisition unit 311 may acquire the first information by inputting a specific input into the input unit 15 after the first information is input into the input unit 15. The specific input is an input for confirming the first information input into the input unit 15. In this case, it is preferable that the specific input is different from the input for calling a person in the second area 72. That is, as described above, the operation unit 151 of the input unit 15 preferably has a confirmation button for confirming the input of the first information in addition to a call button for calling a person in the second area 72. In this case, when the confirmation button is pressed after the first information is input into the input unit 15, the first information input into the input unit 15 is transmitted from the terminal system 1 to the information output system 3, and the first acquisition unit 311 acquires the first information. According to this configuration, it is possible to cause the first acquisition unit 311 to acquire the first information without calling a dwelling unit as the second area 72.

In addition, when the first information is input to the input unit 15 and then a specific input is input to the input unit 15, instead of the first acquisition unit 311 acquiring the first information, the authentication unit 314 may execute the authentication, and the output unit 313 may output third information including the authentication result of the authentication unit 314. In this case, the first acquisition unit 311 acquires the first information between the input of the first information to the input unit 15 and the input of the specific input. With this configuration, it is possible to have the authentication unit 314 execute the authentication without calling up the dwelling unit as the second area 72.

In the first embodiment, the imaging unit 13 performs the imaging process after the notification unit 112 performs the first notification process, and the authentication unit 314 performs the authentication process after the notification unit 112 performs the second notification process. In contrast, the imaging unit 13 may perform the imaging process without the notification unit 112 performing the first notification process, or the authentication unit 314 may perform the authentication process without the notification unit 112 performing the second notification process. That is, in the terminal system 1, when the input unit 15 accepts input of specific information, the imaging unit 13 may perform at least one of an imaging process in which the imaging unit 13 captures a specific image and an output process in which the output unit 111 outputs authentication information. In this case, it is possible to omit the notification unit 112.

In the first embodiment, the terminal system 1 includes an imaging unit 13, and an image captured by the imaging unit 13 is used to authenticate a visitor. However, the image used to authenticate a visitor may be configured to be input to the terminal system 1 from outside. In this case, it is possible to omit the imaging unit 13.

In the first embodiment, the information output system 3 includes the authentication unit 314, and the information output system 3 constitutes the authentication system 9, but for example, the terminal system 1 may include the authentication unit, and the terminal system 1 may constitute the authentication system 9. That is, the authentication system 9 may include the above-mentioned terminal system 1 and an authentication unit that performs authentication of a visitor based on a specific image captured by the imaging unit 13. Even in this case, it is possible to suppress a decrease in convenience while maintaining security.

In the first embodiment, the authentication information is a feature extracted from a face image, but the authentication information is not limited to a feature and may be a face image.

In the first embodiment, the call button and the confirmation button are included in multiple push button switches, but at least one of the call button and the confirmation button may be included in a touch panel.

In the first embodiment, the control device installed in the third area 73 of the collective facility 7 functions as the information output system 3, but for example, at least one of the first acquisition unit 311, the second acquisition unit 312, and the output unit 313 of the information output system 3 may be provided in the terminal system 1 functioning as a lobby intercom. Furthermore, at least one of the first acquisition unit 311, the second acquisition unit 312, and the output unit 313 of the information output system 3 may be provided in the intercom master unit 2. In other words, the information output system may be composed of the control device, the lobby intercom, and the intercom master unit 2.

(Embodiment 2)
3, the terminal system 1 according to the second embodiment differs from the terminal system 1 according to the first embodiment in that the input unit 15 includes a wireless communication unit 152 in addition to an operation unit 151. Hereinafter, the same components as those in the first embodiment will be denoted by the same reference numerals and the description thereof will be omitted as appropriate.

(1) Configuration The terminal system 1 of embodiment 2 includes a control unit 11, a display unit 12, an imaging unit 13, a call unit 14, an input unit 15, a communication unit 16, and a memory unit 17, as shown in FIG. 3 .

The input unit 15 includes an operation unit 151 and a wireless communication unit 152. As described above, the operation unit 151 is an input interface having, for example, a plurality of push button switches and a touch panel.

The wireless communication unit 152 is configured to communicate with the information terminal 8. The wireless communication unit 152 communicates with the information terminal 8 using wireless signals. The information terminal 8 is, for example, a smartphone carried by the visitor. The visitor inputs the first information to the information terminal 8 in the first area 71 of the collective facility 7. As described above, the first information is information for identifying the second area 72, which is an exclusive portion of the collective facility 7, and is, for example, the room number of one of the residences. Then, when the visitor performs a predetermined operation (transmission operation) on the information terminal 8, the first information input to the information terminal 8 is input (transmitted) to the input unit 15 via the wireless communication unit 152. In other words, the first information includes information received by the wireless communication unit 152 from the information terminal 8 carried by the visitor.

As described above, the storage unit 17 is composed of a readable and writable memory such as a flash memory. The storage unit 17 stores, for example, video data of a video (image) captured by the imaging unit 13. The storage unit 17 also stores the above-mentioned authentication information (feature amount of a facial image) and the first information in association with each other. The storage unit 17 also stores the first information transmitted from the information terminal 8 together with the time when the first information was received. The storage unit 17 may be an internal memory of the control unit 11.

(2) Operation Next, the operation of the terminal system 1 and the information output system 3 will be described with reference to FIG.

When a visitor to the collective facility 7 comes in front of the terminal system 1, the control unit 11 causes the imaging unit 13 to capture a specific image including the visitor (imaging step S211). While positioned in front of the terminal system 1, the visitor inputs first information into the information terminal 8. When the visitor then performs a predetermined operation on the information terminal 8, the first information input into the information terminal 8 is input into the input unit 15 via the wireless communication unit 152 (input step S212).

In the terminal system 1, the control unit 11 stores the first information input to the input unit 15 in the storage unit 17 together with the time when the first information was received (storage step S213). If the first information is input to the input unit 15 within a first period after the imaging unit 13 captures the specific image (determination step S214), the control unit 11 reads out authentication information associated with the first information from the storage unit 17 based on the first information input to the input unit 15. The control unit 11 also creates second information including facial features of the visitor from the specific image captured by the imaging unit 13. The control unit 11 then creates a communication signal including the first information, the second information, and the authentication information, and causes the communication unit 16 to transmit the created communication signal to the information output system 3 (output step S215).

In the information output system 3, the control unit 31 acquires the first information, the second information, and the authentication information contained in the communication signal from the terminal system 1 (acquisition step S216). More specifically, the first acquisition unit 311 acquires the first information and the authentication information, and the second acquisition unit 312 acquires the second information. Note that the authentication information may be acquired by the second acquisition unit 312. In this embodiment, the acquisition step S216 is the first acquisition step and the second acquisition step in the information output method.

Next, in the information output system 3, the authentication unit 314 of the control unit 31 performs authentication of the visitor using the authentication information and the second information (authentication step S217). More specifically, the authentication unit 314 compares the features of one or more facial images included in the authentication information with the features of the visitor's face included in the second information, and determines that the authentication of the visitor has been successful if the authentication information contains features that match the features of the visitor's face. Also, the authentication unit 314 determines that the authentication of the visitor has failed if the authentication information does not contain features that match the features of the visitor's face. Then, the control unit 31 creates a communication signal including the authentication result (third information) of the authentication unit 314, and causes the transmission processing unit 32 to transmit the created communication signal to the terminal system 1 (output step S218). Also, if the authentication of the visitor has been successful, the control unit 31 transmits an unlocking signal to the front door 6 (transmission step S219). Then, at the front door 6, the electric lock 61 is unlocked in accordance with the unlocking signal from the information output system 3 (unlocking step S220). In this embodiment, the output step S218 is the output step in the information output method.

Here, in FIG. 4, the input step S212 is executed after the imaging step S211, but the imaging step S211 may be executed after the input step S212. In this case, it is preferable that the authentication unit 314 is configured to execute the authentication process when the imaging unit 13 captures a specific image within a predetermined time after the first information is input to the input unit 15. Also, in this case, the authentication unit 314 may be configured to execute the authentication process when the imaging unit 13 captures a specific image within a predetermined time after the first acquisition unit 311 acquires the first information. Also, in FIG. 4, the transmission step S219 is executed after the output step S218, but the output step S218 may be executed after the transmission step S219.

In the information output system 3 and terminal system 1 according to the second embodiment, the second information is authenticated using authentication information associated with the first information (specific information) input to the input unit 15. This makes it possible to improve security compared to the case where the second information is authenticated using all authentication information. In addition, in the information output system 3 and terminal system 1 according to the second embodiment, the second information can be authenticated simply by inputting information (specific information) for identifying the second area 72 to the input unit 15, so that it is also possible to suppress a decrease in convenience. In other words, the information output system 3 and terminal system 1 according to the second embodiment make it possible to suppress a decrease in convenience while maintaining security.

In addition, in the information output system 3 according to the second embodiment, it is possible to perform authentication of a visitor only when the first information is input to the input unit 15 within a first period after the imaging unit 13 captures a specific image. On the other hand, if the first information is not input to the input unit 15 within a first period after the imaging unit 13 captures a specific image, for example, the notification unit 112 may be configured to notify that effect (for example, "The input of the first information cannot be confirmed", "Authentication is not possible", etc.).

In the second embodiment, the information terminal 8 is a smartphone. However, the information terminal 8 is not limited to a smartphone and may be, for example, a tablet terminal or a PDA (Personal Digital Assistant).

In the second embodiment, authentication of a visitor is performed when the first information is input to the input unit 15 within a first period after the imaging unit 13 captures a specific image. However, for example, authentication of a visitor may be performed when the first acquisition unit 311 acquires the first information within a second period after the imaging unit 13 captures a specific image. That is, in the information output system 3, when the first information is input to the input unit 15 within the first period or when the first acquisition unit 311 acquires the first information within the second period, authentication of the second information against the authentication information is performed, and the output unit 313 outputs the third information. The first period is the period from when the imaging unit 13 captures a specific image to when the first information is input to the input unit 15. The second period is the period from when the imaging unit 13 captures a specific image to when the first acquisition unit 311 acquires the first information.

The various configurations (including modified examples) described in embodiment 2 can be used in appropriate combination with the various configurations (including modified examples) described in embodiment 1.

(Embodiment 3)
5, the terminal system 1 according to the third embodiment differs from the terminal system 1 according to the second embodiment in that the terminal system 1 according to the third embodiment includes a detection unit 18. Hereinafter, the same components as those in the second embodiment will be denoted by the same reference numerals and the description thereof will be omitted as appropriate.

(1) Configuration As shown in FIG. 5 , the terminal system 1 according to the third embodiment includes a control unit 11, a display unit 12, an imaging unit 13, a call unit 14, an input unit 15, a communication unit 16, a memory unit 17, and a detection unit 18.

The detection unit 18 is configured to detect the information terminal 8. For example, the detection unit 18 transmits a beacon signal at regular time intervals, and detects the information terminal 8 based on the radio wave strength of a response signal from the information terminal 8 to the beacon signal. More specifically, the detection unit 18 detects that the information terminal 8 is within a predetermined range when the radio wave strength of a response signal from the information terminal 8 to the beacon signal is equal to or greater than a predetermined threshold.

(2) Operation Next, the operation of the terminal system 1 and the information output system 3 will be described with reference to FIG.

When a visitor to the collective facility 7 comes in front of the terminal system 1, the control unit 11 causes the imaging unit 13 to capture a specific image including the visitor (imaging step S311). While positioned in front of the terminal system 1, the visitor inputs first information into the information terminal 8. When the visitor then performs a predetermined operation on the information terminal 8, the first information input into the information terminal 8 is input into the input unit 15 via the wireless communication unit 152 (input step S312).

In the terminal system 1, the control unit 11 stores the first information input to the input unit 15 in the storage unit 17 together with the terminal information (e.g., address information) of the information terminal 8 that transmitted the first information and the time when the first information was received (storage step S313). Next, when the first information is input to the input unit 15 within a first period after the imaging unit 13 captures a specific image (first determination step S314), the control unit 11 determines whether the information terminal 8 detected by the detection unit 18 matches the information terminal 8 that transmitted the first information (second determination step S315). Then, when the information terminal 8 detected by the detection unit 18 matches the information terminal 8 that transmitted the first information, the control unit 11 reads out the authentication information associated with the first information from the storage unit 17 based on the first information input to the input unit 15. The control unit 11 also creates second information including the facial features of the visitor from the specific image captured by the imaging unit 13. Then, the control unit 11 creates a communication signal including the first information, the second information, and the authentication information, and causes the created communication signal to be transmitted from the communication unit 16 to the information output system 3 (output step S316).

In the information output system 3, the control unit 31 acquires the first information, the second information, and the authentication information contained in the communication signal from the terminal system 1 (acquisition step S317). More specifically, the first acquisition unit 311 acquires the first information and the authentication information, and the second acquisition unit 312 acquires the second information. Note that the authentication information may be acquired by the second acquisition unit 312. In this embodiment, the acquisition step S317 is the first acquisition step and the second acquisition step in the information output method.

Next, in the information output system 3, the authentication unit 314 of the control unit 31 performs authentication of the visitor using the authentication information and the second information (authentication step S318). More specifically, the authentication unit 314 compares the features of one or more facial images included in the authentication information with the features of the visitor's face included in the second information, and determines that the authentication of the visitor has been successful if the authentication information contains features that match the features of the visitor's face. Also, the authentication unit 314 determines that the authentication of the visitor has failed if the authentication information does not contain features that match the features of the visitor's face. Then, the control unit 31 creates a communication signal including the authentication result (third information) of the authentication unit 314, and causes the transmission processing unit 32 to transmit the created communication signal to the terminal system 1 (output step S319). Also, if the authentication of the visitor has been successful, the control unit 31 transmits an unlocking signal to the front door 6 (transmission step S320). Then, at the front door 6, the electric lock 61 is unlocked in accordance with the unlocking signal from the information output system 3 (unlocking step S321). In this embodiment, the output step S319 is the output step in the information output method.

Here, in FIG. 6, the input step S312 is executed after the imaging step S311, but the imaging step S311 may be executed after the input step S312. In this case, it is preferable that the authentication unit 314 is configured to execute the authentication process when the imaging unit 13 captures a specific image within a predetermined time after the first information is input to the input unit 15. Also, in this case, the authentication unit 314 may be configured to execute the authentication process when the imaging unit 13 captures a specific image within a predetermined time after the first acquisition unit 311 acquires the first information. Also, in FIG. 6, the transmission step S320 is executed after the output step S319, but the output step S319 may be executed after the transmission step S320.

In the information output system 3 and terminal system 1 according to the third embodiment, the second information is authenticated using authentication information associated with the first information (specific information) input to the input unit 15. This makes it possible to improve security compared to the case where the second information is authenticated using all authentication information. Furthermore, in the information output system 3 and terminal system 1 according to the third embodiment, the second information can be authenticated simply by inputting information (specific information) for identifying the second area 72 to the input unit 15, so that it is also possible to suppress a decrease in convenience. In other words, the information output system 3 and terminal system 1 according to the third embodiment make it possible to suppress a decrease in convenience while maintaining security.

In addition, in the information output system 3 according to the third embodiment, it is possible to perform authentication of the visitor only when the information terminal 8 detected by the detection unit 18 matches the information terminal 8 that has transmitted the first information. On the other hand, when the information terminal 8 detected by the detection unit 18 does not match the information terminal 8 that has transmitted the first information, for example, the notification unit 112 may be configured to notify that fact (for example, "information terminals do not match", "authentication not possible", etc.).

The various configurations (including modified examples) described in embodiment 3 can be adopted in appropriate combination with the various configurations (including modified examples) described in embodiments 1 and 2.
