Description

[Technical Field]

[0001] The present invention relates to a face authentication system. [Background technology]

[0002] With the recent spread of digital transformation (DX), the range of applications for facial recognition technology is expanding. The main advantages of facial recognition are the convenience and improved security of the authentication process. Unlike knowledge authentication or possession authentication, facial recognition is a form of biometric authentication, and does not require memorization of passcodes or the carrying of personal items. Furthermore, since human facial shapes vary widely, it is difficult for others to imitate. Furthermore, contactless use makes it hygienic and particularly effective as a measure against infectious diseases. Furthermore, technology that can handle changes in environmental illuminance and age has reached a practical level, ensuring stable authentication accuracy. These characteristics make facial recognition promising for application in a wide range of fields. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Publication No. 2023-5614 Summary of the Invention [Problem to be solved by the invention]

[0004] The above-mentioned Patent Document 1 discloses a facial recognition system for apartment buildings. The facial recognition system in Patent Document 1 is designed so that each dwelling unit in the apartment building is a rental property, and a PM (tenant management company) manages the entry and exit of residents, etc.

[0005] On the other hand, in cases such as condominiums, where the management association made up of the owners of each unit manages the building and assets themselves or decides on an outsourced management company, the management entity and responsibility for the facial recognition system become unclear.

[0006] In view of these problems, the present invention provides a facial authentication system that does not require management by a management company or the like, and that can be safely started by residents alone, and that can change users. [Means for solving the problem]

[0007] In order to solve the above problems, the facial authentication system of the present invention comprises a face registration means for registering a user's facial image or facial data that is processed data thereof, a photographing device installed near the front door of a dwelling unit in an apartment building, a resident registration means for registering the user as a resident of the dwelling unit, an authentication means for comparing the face photographed by the photographing device with the facial data of the resident, and a resident tool that is a user interface for the face registration means and the resident registration means, and the user account of the resident tool is handed over to the resident of the dwelling unit along with a key to the front door, and the user account of the resident tool is pre-registered for each dwelling unit in the apartment building.

[0008] A user account for the resident tool, which is equipped with a facial registration means and a resident registration means, is created for each dwelling unit, and by handing over that user account along with the front door key to the resident, the resident can begin using the facial recognition system safely and independently. Furthermore, when changing the user of the facial recognition system from the current resident to a new resident, the current resident can simply hand over the user account to the new resident, and this can be done between the parties without the involvement of the management company. In this case, the new resident changes the password to something unique after handing over the user account.

[0009] In addition, in order to solve the above problem, the face authentication system of the present invention comprises a face registration means for registering a user's face image or face data that is processed data thereof, a photographing device installed near the front door of a dwelling unit in an apartment building, a resident registration means for registering a user as a resident of the dwelling unit, an authentication means for comparing the face photographed by the photographing device with the face data of the resident, a resident tool that is a user interface for the face registration means and the resident registration means, and an administrator tool that is a user interface for approving registration operations by the resident registration means, wherein the user account of the resident tool and the user account of the administrator tool are different user accounts, the user account of the administrator tool is handed over to the resident of the dwelling unit along with the front door key, and the user account of the administrator tool may be registered in advance for each dwelling unit in the apartment building.

[0010] A separate administrator tool is prepared to approve resident registration, and a user account for the administrator tool is created in advance for each apartment. This user account is then handed over to the resident along with the front door key, allowing the resident to begin using the facial recognition system safely and independently. Furthermore, when changing the user of the facial recognition system from the current resident to a new resident, the current resident can simply hand over the administrator tool user account to the new resident, allowing this to be done between the parties without the involvement of the management company. In this case, the new resident changes the password for the administrator tool user account to their own unique one after the handover.

[0011] In addition, in order to solve the above problem, the face authentication system of the present invention comprises a face registration means for registering a user's face image or face data that is processed data thereof, a photographing device installed near the front door of a dwelling unit in an apartment building, a resident registration means for registering a user as a resident of the dwelling unit, an authentication means for comparing a face photographed by the photographing device with the resident's face data, and a resident tool that is a user interface of the face registration means, and in order to execute the resident registration means, the user account of the resident tool must be granted execution authority for the resident registration means, or the user account must be set as the destination of a temporary passcode issued when the resident registration means is executed, and the execution authority for the resident registration means and the destination of the passcode are set on a unit-by-unit basis in the apartment building, and a resident of any of the dwelling units may be configured to be able to transfer the execution authority or the setting of the destination of the passcode to the user account of another person.

[0012] By dividing the authority to execute the resident registration means and the destination of the passcode for each dwelling unit, and by transferring the above-mentioned authority for that dwelling unit to the resident's user account when the front door key is handed over, the resident can safely begin using the facial recognition system on his or her own.In addition, when changing the user of the facial recognition system from the current resident to a new resident, the above-mentioned authority can be transferred from the current resident's user account to the new resident's user account, and this can be done between the parties without the intervention of the management company.

[0013] In addition, in order to solve the above problem, the face authentication system of the present invention comprises a face registration means for registering a user's face image or face data which is processed data thereof, a photographing device installed near the front door of a dwelling unit in an apartment building, a resident registration means for registering a user as a resident of the dwelling unit, an authentication means for comparing a face photographed by the photographing device with the resident's face data, a resident tool which is a user interface of the face registration means, a security token which is a tangible object delivered to a resident of the house and is a device, instrument, or information medium for proving that the resident is a resident of the house, and a fixed code which is an encoded code, a key consisting of a string of characters, or a key consisting of numbers which is delivered to the resident of the house together with the security token, and the resident registration means may be configured to require, when registering a resident, that the user performing the registration operation be in possession of the security token and to input the fixed code. [Effects of the Invention]

[0014] In this way, the face authentication system of the present invention does not require management by a management company or the like, and residents can safely start using the system or change users on their own. [Brief explanation of the drawings]

[0016] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. The facial authentication system F described below is an example of the facial authentication system of the present invention installed in a condominium, which is a multi-family housing complex. When a user registers themselves as a resident of the condominium, the facial authentication system F confirms through property authentication that the person performing the registration operation is a resident of one of the dwelling units. This allows the resident alone to safely start using the facial authentication system F or change users, without the need for identity verification by a management company or the like. Hereinafter, this feature of the facial authentication system F and other associated features will be described using an embodiment as an example.

[0017] <System Overview> 1 is a use case diagram showing an overview of a face authentication system F of this embodiment. The face authentication system F of this embodiment is mainly composed of a server device 20, a user application 30 (resident tool), and an authentication device 40. The authentication device 40 of this embodiment is installed near the dwelling door (front door) of each dwelling unit in an apartment building and near the common entrance door (entrance door of the apartment building).

[0018] The user application 30 is a dedicated application installed on a resident's smartphone (user terminal). The user application 30 is a UI (user interface) that allows the resident to register their facial data in the facial authentication system F and to register themselves as a resident of the apartment building. The authentication device 40 is a device that photographs the face of oncoming people, compares and authenticates the photograph with registered facial data, and unlocks the entrance door and apartment door. The server device 20 communicates with the user application 30 and the authentication devices 40, processes various registration requests from residents, and distributes facial data of legitimate residents to each authentication device 40. Note that the term "resident" here may also include prospective residents who are in the process of moving in.

[0019] Figure 2 is an image diagram showing an example of use of the face authentication system F. Figure 2(a) shows an example of use of an authentication device 40 installed at the entrance door 19 of an apartment building. Figure 2(b) shows an example of use of an authentication device 40 installed at the dwelling door 11 of each dwelling unit 10.

[0020] As shown in FIG. 2(a), an authentication device 40a for the entrance door 19 is installed on a decorative pillar at the common entrance. Residents of the apartment building can open the entrance door 19 by photographing their face with the camera 41 (photographing device) of the authentication device 40a. Also, as shown in FIG. 2(b), an authentication device 40b for the dwelling door 11 is installed adjacent to each dwelling door 11. Residents of each dwelling unit 10 can unlock the dwelling door 11 by photographing their face with the camera 41 of the authentication device 40b. The dwelling door 11 is also equipped with a cylinder lock 111, so residents can also unlock the dwelling door 11 with a key.

[0021] In this way, each resident of the apartment building can use facial recognition to unlock the entrance door 19 and the apartment door 11, so they can enter and exit the apartment building or the apartment 10 without, for example, having to carry a key or memorize a passcode.

[0022] <Functional configuration> 3 is a layout diagram showing the functional configuration of the face authentication system F. Each function of the face authentication system F will be described below with reference to FIG.

[0023] 3, the authentication device 40 and user application 30 of the face authentication system F are network-connected to the server device 20. In this embodiment, the authentication device 40 and user application 30 transmit and receive data to and from the server device 20 via the Internet.

[0024] As described above, the user application 30 is a dedicated application installed on the resident's smartphone. The user application 30 may take the form of a smartphone application, dedicated software installed on the resident's PC, or a web service provided using a web browser. The user application 30 includes a camera 31 that captures the resident's face and an operation panel 32 that performs various operations on the facial authentication system F. In this embodiment of the facial authentication system F, the resident's smartphone is used as the UI for the facial authentication system F, thereby improving usability compared to using dedicated equipment whose operation is unknown. Furthermore, by reducing the amount of dedicated equipment required to use the facial authentication system F, the implementation costs of the facial authentication system F and the management burden on residents are reduced.

[0025] The server device 20 of this embodiment includes a user registration program 21 (face registration means), a user database 25, a resident registration program 22, and token data 27. Hereinafter, a resident from the perspective of the facial authentication system F will also be referred to as a "user" as appropriate. The user registration program 21 is a program that registers a facial image P of a user of the facial authentication system F and registers user data 26, which is the user's personal information and attribute information, in the user database 25. The resident registration program 22 is a program that registers a user as a resident of one of the dwelling units 10 in an apartment building in which the facial authentication system F is installed. The token data 27 is data used to verify that the person performing the registration operation is a legitimate resident. Specifically, the token data 27 is data such as the serial number, secret key, and one-time password of the hardware token 26 described below. The server device 20 distributes the facial image P of a user registered as a resident of one of the dwelling units 10 to the authentication device 40a of the entrance door 19 and the authentication device 40b of the dwelling door 11 of that dwelling unit 10.

[0026] The server device 20 of this embodiment is a virtual server constructed using a cloud hosting service. The construction method of the server device 20 is not limited to a cloud server, and the server device 20 may be an on-premise server installed in a LAN of a business operator that provides the face authentication system F or in a LAN of an apartment building.

[0027] Each authentication device 40 has a camera 41 that captures the face of an oncoming person and an authentication program 42 that compares and authenticates the face captured by the camera 41 with a pre-registered face template T. The face template T here is biometric data for comparison that extracts features of a face image P distributed from the server device 20, and may also be called a face vector, feature amount, face map, etc. in addition to being called a face template. Each authentication device 40 converts the face image P distributed from the server device 20 into a face template T using the same algorithm as the authentication program 42, and stores the converted face template T. In other words, the face authentication system F of this embodiment is a so-called edge-type face authentication system.

[0028] The physical layout of each function shown in FIG. 3 is merely an example and is not limited to the configuration of this embodiment. The layout of these functions can be changed as appropriate depending on the characteristics, size, number of users, budget, and other implementation and operational constraints and requirements of the facility where the face authentication system F is installed. For example, the authentication program 42 and face template T may be stored in the server device 20, creating a cloud-based face authentication system. In this case, it is also possible to delegate the face matching and authentication functions to an external service. It is also possible to install an operation panel 32 on the authentication device 40 and have the UI functions of the user application 30 stored in, for example, each authentication device 40b.

[0029] <How to hand over the property> Fig. 4 is an image diagram illustrating a method for handing over a dwelling unit 10. In order for a resident to start using the facial authentication system F, the resident must create a user account 30a for the facial authentication system F and register himself / herself as a resident of one of the dwelling units 10. When registering a resident, the resident registration program 22 of the facial authentication system F in this embodiment checks whether the user performing the registration operation has a hardware token 36 (security token).

[0030] When the dwelling unit 10 is handed over in this embodiment, as shown in Figure 4(a), if the dwelling unit 10 is a new property, the developer hands it over to the prospective resident (property buyer), or if the dwelling unit 10 is a used property, the current resident hands it over to the new resident along with a key 39 for the dwelling unit door 11, as shown in Figure 4(a). The hardware token 36 is a device that displays a one-time password (temporary passcode).

[0031] The hardware token 36 is provided with a three-dimensional code Q (fixed code) for identifying the individual hardware token 36, and this three-dimensional code Q is also handed over together with the hardware token 36. Here, the three-dimensional code Q may be any information that can uniquely identify the hardware token 36, that is, information that is specific to each hardware token 36, and may be any other encoded code such as a two-dimensional code, a key consisting of a character string, or a key consisting of a numerical value.

[0032] Furthermore, in this embodiment, the hardware token 36 is prepared for each dwelling unit 10. In other words, the serial number and secret key of the hardware token 36 are associated with one of the dwelling units 10. The resident registration program 22 registers a user who possesses the hardware token 36 as a resident of the dwelling unit 10 associated with that hardware token 36. In this embodiment, since a hardware token 36 is prepared for each dwelling unit 10, the resident of each dwelling unit 10 can independently start using the facial recognition system F or change the user of the facial recognition system F for that dwelling unit 10 from the current resident to a new resident.

[0033] When a resident registers himself / herself as a resident of one of the dwelling units 10, the resident scans the three-dimensional code Q with the camera 31 of the user application 30 to have the resident registration program 22 recognize the identity (serial number, etc.) of the hardware token 36, and then enters the one-time password displayed on the hardware token 36 to prove that he / she possesses the hardware token 36. As a result, the resident registration program 22 determines that the user performing the operation is a legitimate resident and registers the user as a resident of the dwelling unit 10.

[0034] In this way, in the facial authentication system F of this embodiment, the resident registration program 22 confirms possession of the hardware token 36 at the time of registration, thereby preventing resident registration by unrelated third parties and allowing only legitimate users to register as residents of the dwelling unit 10. In particular, the use of the hardware token 36, which is a tangible object, increases the security level of resident registration to the authentication strength of property authentication. This eliminates the need for identity verification by a management company or the like, allowing residents to safely begin using the facial authentication system F on their own. Furthermore, when changing the user of the facial authentication system F from the current resident to a new resident, the current resident can simply hand over the three-dimensional code Q and the hardware token 36 to the new resident, and this can be done between the parties without the intervention of a management company or the like.

[0035] <Registration process> 5 is a sequence diagram showing the process of various registration operations for the face authentication system F. Here, the processes will be explained in the order of user registration, resident registration, and co-housemate registration for the face authentication system F.

[0036] (User registration) When a resident registers a user account 30a in the facial authentication system F, the resident first installs the user application 30 on his / her smartphone and sets a user ID and password. Then, the resident inputs his / her personal information and facial image P through the user application 30. The user registration program 21 stores the input user data 26 such as the user ID and the facial image P in the user database 25. This completes user registration in the facial authentication system F.

[0037] (Resident Registration) When a user registers himself / herself as a resident of one of the dwelling units 10, the user first performs a prescribed operation for resident registration in the user application 30. The resident registration program 22 of the server device 20 receives this operation and requests the user to read the three-dimensional code Q. When the user scans the three-dimensional code Q at hand with the camera 31, the resident registration program 22 identifies the individual hardware token 36 from the restored data of the three-dimensional code Q and requests the user to enter a one-time password. When the user enters the one-time password displayed on the hardware token 36 at hand, the resident registration program 22 checks whether the password is correct. If the one-time password is correct, the resident registration program 22 determines that the user is the owner of the hardware token 36 (authentication successful) and distributes a facial image P of the user to each authentication device 40. Each authentication device 40 converts the facial image P distributed from the server device 20 into a face template T and notifies the server device 20 of the completion of the registration process. The resident registration program 22 receives this notification and notifies the user of the completion of resident registration.

[0038] As described above, in the face authentication system F of this embodiment, the process of registering a user of the face authentication system F and the process of registering the user as a resident of the dwelling unit 10 are separate processes. In this embodiment, being a resident of the dwelling unit 10 is set as one attribute of the user's user account 30a. Furthermore, although the one-time password displayed by the hardware token 36 of this embodiment is primarily a password consisting of numbers, it is also possible to display other passwords, such as a temporary three-dimensional code, a two-dimensional code, a temporary passphrase consisting of text, or a temporary one-stroke pattern.

[0039] (Cohabitant registration) The face authentication system F of this embodiment is equipped with a housemate registration program 23 that allows a user registered as a resident to additionally register housemates, such as family members, living in the dwelling unit 10. This function allows all family members, even in households with small children, to use the face authentication system F. To register a housemate, the resident inputs the housemate's personal information and face image P through the user application 30. The housemate registration program 23 receives this operation and distributes the housemate's face image P to each authentication device 40. Each authentication device 40 converts the face image P distributed from the server device 20 into a face template T and notifies the server device 20 that the registration process is complete. The housemate registration program 23 receives this notification and notifies the user that the housemate registration is complete. As a result, each authentication device 40 compares the captured face not only with the resident's face template T but also with the housemate's face template T.

[0040] <Unsubscription process> FIG. 6 is a sequence diagram showing the process of canceling resident registration in the face authentication system F. In this embodiment of the face authentication system F, the resident registration program 22 also serves as the cancellation function (registration cancellation means). There are two main methods for canceling resident registration: one is to delete only the resident registration associated with the operator's (resident's) own user account 30a (individual cancellation), and the other is to delete all residents and co-residents registered for the residence 10, including other user accounts 30a such as previous residents (bulk cancellation). Each method will be explained below in this order.

[0041] (Individual cancellation) When a resident wants to unlock the resident registration of a resident or housemate associated with their own user account 30a, the resident performs an individual unlocking operation in the user application 30. The resident registration program 22 of the server device 20 receives this request and instructs each authentication device 40 to delete the face template T of the resident or housemate associated with the user account 30a. Each authentication device 40 deletes or invalidates the face template T instructed by the server device 20 and notifies the server device 20 of the completion of the deletion process. The resident registration program 22 receives this notification and notifies the resident that the registration cancellation is complete.

[0042] (Bulk cancellation) When canceling all resident registrations of residents and cohabitants registered for a residence 10, the resident first performs a prescribed operation for a bulk cancellation operation in the user application 30. The resident registration program 22 of the server device 20 receives this operation and requests the user to scan a three-dimensional code Q. When the resident scans the three-dimensional code Q in their hand with the camera 31, the resident registration program 22 identifies the individual hardware token 36 from the three-dimensional code Q and requests the resident to enter a one-time password. When the resident enters the one-time password, the resident registration program 22 checks whether it is correct. If the one-time password is correct, it determines that the user is the owner of the hardware token 36 (authentication successful) and instructs each authentication device 40 to delete all face templates T for that residence unit 10. In response to this instruction, each authentication device 40 deletes or invalidates all face templates T for the residence unit 10 and notifies the server device 20 of the completion of the deletion process. The resident registration program 22 receives this notification and notifies the resident of the completion of the bulk cancellation.

[0043] In this way, in the face authentication system F of this embodiment, a user who is registered as a resident of a dwelling unit 10 can also cancel the resident registration of the user account 30a that was previously registered as a resident of that dwelling unit 10. This allows the new resident to smoothly change the resident registration on their own, even if the previous resident forgot to cancel the resident registration or was unable to cancel it for some reason. Note that the resident can optionally and individually cancel the resident registration of a co-resident associated with the resident's own user account 30a.

[0044] <Modification> In the above embodiment, a hardware token 36 is used as a tangible object, i.e., a security token, that proves that the person is a resident of the dwelling unit 10. A security token that can be used with the facial authentication system F is a unique tangible object associated with the dwelling unit 10, and it is sufficient if its possession can be confirmed electronically. In addition to the hardware token 36, it may also be, for example, a card or hardware with an integrated IC chip, or a computer peripheral device on which unique specific data is recorded.

[0045] 4(b) is a diagram illustrating a modification of the above embodiment, in which an NFC-compliant IC card 37 or a USB token 38 is used instead of the hardware token 36. In the above embodiment, because the hardware token 36 only has the function of displaying a one-time password, it was necessary to identify the individual hardware token 36 by the three-dimensional code Q. When an IC card 37 or a USB token 38 is used instead of the hardware token 36, data for identifying the individual can be included in the IC card 37 or the USB token 38, so there is no need to use the three-dimensional code Q.

[0046] Fig. 7(a) is a sequence diagram showing the resident registration process when an IC card 37 is used as the security token. Fig. 7(b) is a sequence diagram showing the resident registration process when a USB token 38 is used as the security token. In each example of Fig. 7, the only difference is the possession that the resident registration program 22 uses to verify the legitimacy of the user; other configurations of the face authentication system F are the same as those of the above embodiments.

[0047] As shown in FIG. 7(a), when performing resident registration using an IC card 37, the user first performs a specified operation for resident registration in the user application 30. The resident registration program 22 in the server device 20 receives this operation and requests the user to read the IC card 37. When the user scans their IC card 37 with the NFC reader of their smartphone, the resident registration program 22 checks the data of the scanned IC card 37. If the IC card 37 is valid (authentication successful), the resident registration program 22 distributes the user's facial image P to each authentication device 40 on the dwelling door 11 and entrance door 19 associated with the IC card 37. The subsequent process is the same as in the above embodiment.

[0048] As shown in Figure 7(b), when performing resident registration using a USB token 38, the user connects the USB token 38 to their PC and performs a specified operation for resident registration, for example, from the user application 30 of a web service. The resident registration program 22 of the server device 20 receives this operation and checks the data of the USB token 38 connected to the PC. If the USB token 38 is valid (authentication successful), the facial image P of the user is distributed to each authentication device 40 on the dwelling door 11 and entrance door 19 associated with the USB token 38. The subsequent process is the same as in the above embodiment.

[0049] <Other embodiments> 8 and 9 are diagrams illustrating another embodiment of the face authentication system of the present invention. In the following description, only the differences from the above embodiment will be described. Parts not specifically described may be considered to be the same as or similar to the above embodiment. Furthermore, components with the same reference numerals as the above embodiment are the same as or similar to the components of the above embodiment. Furthermore, in the following description, for convenience, the above embodiment will also be referred to as the "main embodiment."

[0050] FIG. 8 is an image diagram illustrating a method for handing over a dwelling unit 10 in another embodiment. FIG. 9 is a sequence diagram showing the process of resident registration using an administrator application 50 (administrator tool). In the above embodiment, the security level of resident registration in the face authentication system F is increased to the authentication strength of possession authentication by using a hardware token 36. On the other hand, the method of identity verification in the face authentication system of the present invention is not limited to possession authentication. Each of the embodiments described below is an example in which identity is verified by access control of the user account of the face authentication system, without using a tangible security token or token data 27.

[0051] (Another embodiment 1) In the above embodiment, the user application 30, the user account 30a, and the server device 20 that constitute the face authentication system F are not limited to use within one apartment building, but are designed to be shared with face authentication systems in other facilities. On the other hand, in the example of FIG. 8(a), the user account 30a is limited to use within one apartment building, and a user account 30a is prepared in advance for each dwelling unit 10. In other words, in the example of FIG. 8(a), the user account 30a is a user account dedicated to the face authentication system of that apartment building (hereinafter referred to as "face authentication system Fb" for convenience), and will not be used outside of the face authentication system Fb.

[0052] In the example of FIG. 8(a), when the property is handed over, the user account 30a of the facial authentication system Fb is handed over along with the key 39. That is, the user ID and password of the user account 30a for the dwelling unit 10 are notified to the prospective resident. After the user account 30a is handed over, the prospective resident changes the personal information, attribute information, and password of the user account 30a to their own. The prospective resident can use this user account 30a to register themselves as a resident of the dwelling unit 10 and to register cohabitants. In the example of FIG. 8(a), the resident registration program 22 determines that a person is a resident of the dwelling unit 10 by knowing the user ID and password of the user account 30a. Therefore, possession of a security token or the like is not required for various operations. Alternatively, when resident registration or bulk cancellation is performed, a one-time password may be sent by push notification to the user app 30, or the one-time password may be sent to the email address or phone number (SMS receiving number) set in the user account 30a and input.

[0053] 8(a), a user account 30a of the user application 30 is created for each dwelling unit 10, and the user account 30a is handed over to the prospective resident together with the key 39, allowing the resident alone to safely begin using the facial authentication system Fb. Also, when changing the user of the facial authentication system Fb from the current resident to a new resident, the current resident can hand over the user account 30a to the new resident, and this can be done between the parties without the intervention of the management company.

[0054] (Another embodiment 2) In the example of FIG. 8(b), as in the main embodiment, the user account 30a is also used in a facial authentication system of another facility. In the example of FIG. 8(b), when the property is handed over, the authority 60 to execute the resident registration program 22, the cohabitant registration program 23, and the like is handed over along with the key 39. The execution authority 60 is divided for each dwelling unit 10, and the prospective resident is granted only the execution authority 60 for that particular dwelling unit 10. By granting this execution authority 60 to the user account 30a, the prospective resident can register themselves as a resident of that dwelling unit 10 and register cohabitants. In the example of FIG. 8(b), the resident registration program 22 determines that the user is a resident of that dwelling unit 10 when the execution authority 60 is granted to the user account 30a. Therefore, various operations do not require the possession of a security token or the like.

[0055] Here, instead of or in addition to the execution authority 60, when the resident registration program 22 performs resident registration or bulk cancellation, it is also possible to change the setting of the destination to which a temporary passcode is sent to the prospective resident's user account 30a. The passcode may be sent, for example, by push notification to the user application 30, or to an email address or telephone number (SMS receiving number) set in the user account 30a.

[0056] In this way, in the example of FIG. 8(b), the execution authority 60 for the resident registration program 22 and the settings for the destination of the passcode D are divided for each dwelling unit, and these settings for that dwelling unit 10 are transferred to the prospective resident's user account 30a along with the transfer of the key 39, allowing the parties involved to safely begin using the facial authentication system on their own. Furthermore, when changing the user of the facial authentication system from the current resident to a new resident, the execution authority 60 and the settings for the destination of the passcode can be transferred between the parties involved without the intervention of the management company by transferring the execution authority 60 and the settings for the destination of the passcode from the current resident's user account 30a to the new resident's user account 30a. Possible methods for transferring the execution authority 60 and the settings for the destination of the passcode include, for example, the current resident or developer displaying a 3D code for transfer on the screen of their own user app 30 and scanning it with the prospective resident's user app 30, or the current resident or developer specifying the destination user account 30a in their own user app 30 and setting a simple password, which the prospective resident's user account 30a receives and enters the password separately notified to them.

[0057] (Other embodiment 3) In the example of FIG. 8(c), as in the main embodiment, the user account 30a is also used in face authentication systems at other facilities. In the example of FIG. 8(c), an administrator tool 50, which is a UI for performing approval operations for requests such as resident registration from the user application 30, is provided in addition to the user account 30a of the user application 30. An administrator account 50a, which is a user account for the administrator tool 50, is provided for each dwelling unit 10. In the example of FIG. 8(c), when the property is handed over, the administrator account 50a for that dwelling unit 10 is handed over along with the key 39. In other words, the user ID and password for the administrator account 50a are notified to the prospective resident. After the administrator account 50a is handed over, the prospective resident changes the password for the administrator account 50a to their own.

[0058] FIG. 9 shows the resident registration process in the example of FIG. 8(c). When a resident performs a resident registration operation using the user application 30, the request is sent to the administrator application 50. The resident logs in to the administrator application 50 using the administrator account 50a and approves their request. This causes the resident registration program 22 to distribute the user's facial image P to each authentication device 40. In the example of FIG. 8(c), the resident registration program 22 also determines that the resident is a resident of the dwelling unit 10 by knowing the user ID and password of the administrator account 50a. Therefore, possession of a security token or the like is not required for various operations, but for security reasons, a temporary passcode may be sent to the administrator account 50a when approval is made using the administrator tool 50.

[0059] As such, in the example of Figure 8(c), a separate administrator tool 50 is prepared to perform approval operations for the resident registration program 22, and an administrator account 50a of the administrator tool 50 is created for each dwelling unit 10. Then, by handing over the administrator account 50a along with the key 39 to the prospective resident, the resident can safely begin using the facial recognition system on their own. Also, when changing the user of the facial recognition system from the current resident to a new resident, by handing over the administrator account 50a from the current resident to the new resident, this can be done between the parties without the intervention of the management company.

[0060] Although the embodiments of the present invention have been described above, the scope of the present invention is not limited thereto, and various modifications can be made without departing from the spirit of the invention. For example, although the above embodiments are examples in which the face recognition system of the present invention is introduced into a condominium, the face recognition system of the present invention can also be applied to, for example, detached houses for sale, rental properties, etc. [Explanation of symbols]
