Description

Beacon-based access control system and method thereof

The present invention relates to a beacon-based access control system and method therefor. More particularly, it relates to a system capable of improving user convenience by automating access control of a user using a Bluetooth-based beacon, and a method of operating the system.

In multi-unit houses such as apartments and officetels, the communal entrance is normally closed, restricting the entry of outsiders. In addition to the common entrance, a door is installed in a place where only authorized users can enter, and access by unauthorized persons is restricted.

In order to open the door of the common entrance, the most common method is to enter a password through the lobby phone. However, in the password input method, the user's convenience is lowered because the input action itself is cumbersome. In addition, since the risk of password leakage is high, the security effect cannot be regarded as high.

In order to improve the user convenience problem, a technology for providing a resident with a radio frequency identification (RFID) or near field communication (NFC) card and allowing the door to be opened through card reading has been proposed. However, since the presented technology also requires a user action such as taking out a card and tagging the card, the user convenience problem is still unresolved.

Accordingly, there is a need for an access control system that can improve user convenience by automatically opening the door when the user approaches the door without requiring a specific action for access from the authorized user.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Advantages and features of the present invention and methods of achieving them will become apparent with reference to the embodiments described below in detail in conjunction with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, but may be implemented in various different forms, and only these embodiments allow the disclosure of the present invention to be complete, and common knowledge in the art to which the present invention pertains It is provided to fully inform those who have the scope of the invention, and the present invention is only defined by the scope of the claims. Like reference numerals refer to like elements throughout.

Unless otherwise defined, all terms (including technical and scientific terms) used herein may be used with the meaning commonly understood by those of ordinary skill in the art to which the present invention belongs. In addition, terms defined in a commonly used dictionary are not to be interpreted ideally or excessively unless clearly defined in particular. The terminology used herein is for the purpose of describing the embodiments and is not intended to limit the present invention. In this specification, the singular also includes the plural unless specifically stated otherwise in the phrase.

As used herein, "comprises" and/or "comprising" refers to the presence of one or more other components, steps, operations and/or elements mentioned. or addition is not excluded.

Hereinafter, some embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 illustrates an exemplary environment in which a beacon-based access control system according to some embodiments of the present invention may be built. In particular, FIG. 1 shows an example of controlling entry and exit of a household resident through a target door installed in a common entrance.

The common entrance shown in FIG. 1 refers to an entrance connecting indoors and outdoors in a multi-family house such as an apartment or officetel. Although the common entrance is generally installed on the first floor of a building, it may be installed in a passageway connected to an underground or above-ground parking lot depending on the structure of the building.

Typically, the lobby phone 10 is installed adjacent to a common front door, and is used for calling a specific household, for performing authorization authentication required to open the common front door, and the like. The authorization authentication is performed by, for example, password input, fingerprint recognition, RFID or NFC tagging. However, as described above, since the enumerated authorization authentication method requires an active user action (e.g. tagging action, password input, etc.), the user's convenience is reduced. In particular, in the case of a place where the same person frequently enters and exits, such as a common entrance, the user may feel more inconvenient because the exemplified action has to be performed every time the user enters and exits.

According to some embodiments of the present invention, automatic access control may be performed without requiring a user action by using a beacon device, the user terminal 20 possessed by the user, and a server communicating with the user terminal 20 . That is, when the user approaches the target door (eg, the common front door), the door opening may be performed automatically. Accordingly, the user can enter and exit the target door more conveniently and safely.

The beacon device is installed adjacent to the target door. For example, the beacon device may be installed in the lobby phone 10 . Hereinafter, for convenience of explanation, the description will be continued by taking as an example that a beacon device is installed in the lobby phone. However, the scope of the present invention is not limited thereto.

In addition, the access control system according to some embodiments of the present invention may be built in various places other than the common entrance hall where access control for the target door is performed according to access authority. For example, it may be utilized when controlling the entrance and exit of a parking lot. However, for convenience of description, the description will be continued by taking as an example that the access control system is built in a common entrance.

Hereinafter, the configuration and operation of the beacon-based access control system according to some embodiments of the present invention will be described in detail.

2 is a block diagram of a beacon-based access control system according to a first embodiment of the present invention.

Referring to FIG. 2 , the access control system may be configured to include a lobby phone 100 , a user terminal 200 , and a server 300 . However, this is only a preferred embodiment for achieving the object of the present invention, and it goes without saying that some components may be added or deleted as needed. In addition, it should be noted that each of the components of the beacon-based access control system shown in FIG. 2 represents functionally separated functional elements, and at least one component may be implemented in a form that is integrated with each other in an actual physical environment. do. Hereinafter, each component of the access control system will be described.

In the access control system according to the first embodiment, the lobby phone 100 is installed in a common entrance and performs a function of controlling the opening/closing operation of a target door and at the same time, a device that periodically or aperiodically transmits a Bluetooth-based beacon message to be. Precisely, the beacon device mounted on the lobby phone 100 transmits a beacon message and broadcasts a BLE (bluetooth low energy) type beacon message. The configuration and operation of the lobby phone 100 will be described later with reference to FIG. 14 .

In the access control system according to the first embodiment, the user terminal 200 is a terminal possessed by a user who enters through the target door. The user terminal 200 transmits a response message to the server 300 in response to receiving the beacon message. If a Bluetooth-based beacon message can be received, the user terminal 200 may be implemented as any device, such as a wearable device such as a smart phone, a tablet PC, or a smart watch. In particular, FIG. 2 illustrates a case in which a plurality of user terminals 200a to 200n exist as a plurality of users each possess the terminal 200 as an example.

In the access control system according to the first embodiment, the server 300 is a computing device that performs authorization verification for a user in response to receiving the response message and determines whether to open or close a target door. The computing device may be a notebook computer, a desktop computer, a laptop computer, etc., but is not limited thereto, and may include all types of devices equipped with calculation means and communication means. The configuration and operation of the server 300 will be described later with reference to FIG. 15 .

For reference, although the server 300 is illustrated as a single computing device in FIG. 2 , it may be implemented as a cloud system including a plurality of computing devices depending on the scale of the system.

In the access control system according to the first embodiment, the lobby phone 100 and the server 300 may communicate through, for example, a network in a building. However, FIG. 2 only shows an example of the present invention, and the scope of the present invention is not limited thereto.

In the access control system, the user terminal 200 and the server 300 may communicate through a network. The network will usually be implemented as a wireless network, such as a mobile radio communication network or Wibro (Wireless Broadband Internet), but the scope of the present invention is not limited thereto.

So far, the beacon-based access control system according to the first embodiment of the present invention has been described with reference to FIG. 2 . Next, an operation process of the access control system according to the first embodiment will be described with reference to FIG. 3 .

3 is a flowchart illustrating an operation process of an access control system according to an embodiment of the present invention.

Referring to FIG. 3 , in step S100 , the lobby phone 100 transmits a beacon message. For example, the lobby phone 100 broadcasts a beacon message periodically or aperiodically.

The beacon message includes identification information (hereinafter, referred to as “first identification information”) of the target door. The first identification information is used to identify a target door to be controlled. In addition, the first identification information is used to verify whether the user has access to the target door. This is because the user's access right may be set differently for each target door.

The first identification information may be defined as, for example, an ID of a target door, a location of the target door, and the like, but the first identification information is not limited to the listed examples. As long as the target door can be identified, any information may be used as the first identification information.

According to an embodiment of the present invention, as shown in FIG. 4 , the first identification information may be recorded in the proximity UUID field 51 of the beacon message 50 . 4 shows a format of a standard beacon message, which is obvious to those skilled in the art, and a description thereof will be omitted.

Meanwhile, according to an embodiment of the present invention, the transmission distance of the beacon message may be set differently for each time zone. For example, the transmission distance of the beacon message may be set to a relatively long distance during the daytime, and set to a relatively short distance during the night time. This can be understood in consideration of the fact that night time is generally vulnerable to security. In this embodiment, the setting of the transmission distance may be performed by the server 300 or the lobby phone 100 . For example, the server 300 may adjust the transmission distance of the beacon message for each time zone. Alternatively, information on a transmission distance of a beacon message for each time zone may be preset in the lobby phone 100 , and the lobby phone 100 may adjust a transmission distance of a beacon message according to the set information.

Referring back to FIG. 3 , in step S110 , in response to the reception of the beacon message, the user terminal 200 transmits a response message to the server 300 . In more detail, without user intervention, a dedicated app preloaded on the user terminal 200 transmits the response message to the server 300 .

According to an embodiment of the present invention, the user terminal 200 transmits the response message to the server 300 rather than the lobby phone 100 . That is, the lobby phone 100 only broadcasts a beacon message and does not receive a response message from the user terminal 200 . Therefore, there is no need to perform a Bluetooth pairing process between the user terminal 200 and the lobby phone 100, and restrictions on the number of pairs do not apply to this embodiment. Accordingly, the access control system according to the embodiment of the present invention can be built without restrictions in an environment in which a large number of users exist.

The response message includes first identification information on the target door and identification information on the user (hereinafter referred to as “second identification information”). In this case, the second identification information may be, for example, a user ID, an ID of a user terminal, a phone number of the user terminal, etc., but the second identification information is not limited to the listed examples. As long as the user can be identified, any information may be used as the second identification information.

According to an embodiment of the present invention, as shown in FIG. 5 , in the response message 70 , in addition to the first identification information 75 and the second identification information 71 , the signal of the beacon message measured by the user terminal 200 . Intensity information 73 may be further included. The signal strength information 73 may be, for example, a received signal strength indicator (RSSI), but may be other information. According to an embodiment, the response message 70 may include signal strength information 73 and/or distance information between the user and the lobby phone 100 calculated using the signal strength of the beacon message. In addition, identification information such as a complex in which the user resides, a building, a lake, etc. may be further included.

Referring back to FIG. 3 , in step S120 , the server 300 verifies the access authority of the user who possesses the user terminal 200 . For example, the server 300 may determine whether the user who has transmitted the response message has the authority to access the target door by using the pre-registered user authority information. In more detail, the server 300 identifies the target door through the first identification information included in the response message, and identifies the user through the second identification information included in the response message. In addition, the server 300 determines whether or not the user has the authority to access through the target door using the pre-registered authority information of the user.

For reference, the user may pre-register permission information through a dedicated app mounted on the user terminal 200 (e.g., register as a resident of the household), and at this time, an appropriate authentication procedure may be performed.

In step S130 , the server 300 determines whether to open or close the target door using the verification result of step S120 .

In step S140 , in response to the decision to open the target door, the server 300 transmits a door open message to the lobby phone 100 . However, according to an embodiment, when the server 300 can directly control the target door, the server 300 may directly transmit a control message for opening the door to the target door. Also, when a separate device for controlling the target door exists, the server 300 may transmit the door open message to the separate device. Hereinafter, the description will be continued on the assumption that the lobby phone 100 performs a function of controlling the target door.

In step S150, the target door is opened. For example, as the lobby phone 100 transmits a door open signal to the target door, the target door may be opened.

So far, the configuration and operation of the beacon-based access control system according to the first embodiment of the present invention has been described with reference to FIGS. 2 to 5 . Next, a beacon-based access control system according to a second embodiment of the present invention will be described with reference to FIG. 6 .

6 is a block diagram of a beacon-based access control system according to a second embodiment of the present invention.

Referring to FIG. 6 , the access control system according to the second embodiment may be configured to further include a household phone 400 . In particular, FIG. 6 illustrates a case in which the generation phone 400 is installed in each of a plurality of households and the plurality of generation phones 400a to 400b exist as an example.

In the access control system according to the second embodiment, the household phone 400 may control the door lock installed on each household door. In addition, the household phone 400 may communicate with the server 300 and/or the lobby phone 100 through a building network.

In this embodiment, when the user's access right is verified, the server 300 inquires the pre-stored user's household information, and transmits a door lock release message to the household phone 400 in which the user resides by using the inquired household information. can do. For example, in response to the decision to open the target door installed in the common entrance, the server 300 may transmit a door lock release message to the household phone in which the user resides. According to the present embodiment, the user may not perform any action to open the door until the user arrives at the household in which he or she resides. Accordingly, user convenience can be further increased.

In addition, according to an embodiment of the present invention, the time at which the server 300 transmits the door lock release message may vary by using the distance from the common entrance to the household in which the user resides. For example, as the distance from the common entrance to the household increases, the door unlock message may be transmitted later. This is to prevent the household door from being opened before the user approaches the household in which he or she resides. According to this embodiment, the opening time of the household door can be minimized.

So far, the beacon-based access control system according to the second embodiment of the present invention has been described with reference to FIG. 6 . Hereinafter, a beacon-based access control system according to a third embodiment of the present invention will be described with reference to FIG. 7 .

7 is a configuration diagram of a beacon-based access control system according to a third embodiment of the present invention. In particular, FIG. 7 illustrates an example in which the access control system is built in a large-scale facility in which a common entrance exists for each complex.

Referring to FIG. 7 , the access control system according to the third embodiment may be configured to further include gateways 510a to 510n for each complex. Also, sub-networks 500a to 500n may be configured for each complex. Each of the gateways 510a to 510n may relay communication between the sub-networks 500a to 500n of the corresponding complex and the server 300 .

In this embodiment, when the server 300 transmits a door open message to the lobby phone 100a installed adjacent to the target door, the door open message is transmitted to the lobby phone 100a through the gateway 510a of the sub-network 500a. ) is forwarded. Since the operation of the access control system according to the third embodiment is similar to that of the access control system according to the first embodiment, further description will be omitted.

So far, an access control system according to a third embodiment of the present invention has been described with reference to FIG. 7 . Hereinafter, some embodiments of the present invention that can be performed together with the access control operation in the above-described access control system will be described with reference to FIGS. 8 to 13 .

First, FIGS. 8 and 9 are diagrams for explaining a method of providing a notification service to an authorized user according to an embodiment of the present invention.

According to an embodiment of the present invention, a notification service may be provided through the lobby phone 100 to a user (hereinafter, referred to as an “authorizer”) who is granted access through authorization verification. Specifically, the server 300 may inquire a notification message related to the authorization by using the second identification information on the authorizer, and allow the inquired notification message to be provided through the lobby phone.

For convenience of understanding, it will be further described with reference to FIG. 8 , when an authorized person enters a household through a target door installed in the common entrance, for example, notification messages 151 and 153 regarding unreceived parcels are displayed. It may be provided through the lobby phone 100 . The notification message may be displayed on the lobby phone 100 like the message 151 or provided as a voice message through the lobby phone 100 like the message 153 . Although a courier receipt message is shown as an example of the notification message in FIG. 8 , this is merely an example for providing convenience of understanding, and may vary according to the location and/or user where the access control system is constructed.

According to an embodiment, the type of notification message, whether the notification message is provided, etc. may be implemented to be set by the user through a dedicated app mounted on the user terminal 200 . In this case, the user may provide a customized notification service for each user by setting the type of message for which the user wants to be notified through the dedicated app.

Meanwhile, according to an embodiment of the present invention, the notification service may operate to be provided only under certain conditions in consideration of the privacy of the authorizer. For example, the notification service may be provided only when there is no or few other users accessing the common entrance hall. In this case, the server 300 may determine whether the number of people present in the vicinity of the common entrance is less than or equal to a preset threshold, and determine whether to provide the inquired notification message using the result of the determination.

In this embodiment, the number of people present in the vicinity of the common entrance may be obtained through a surveillance image of a CCTV (closed circuit television) installed adjacent to the common entrance as shown in FIG. 9 . More precisely, the number of people located in the vicinity of the common entrance may be counted through video analytics for the surveillance image. Alternatively, the number of people may be determined using the number of different second identification information received for a preset time. However, since the number of different second identification information does not include a person possessing a user terminal that has not responded to the beacon message, somewhat inaccurate information may be derived.

According to an embodiment of the present invention, when other users exist in the vicinity of the common entrance, the manner in which the notification service is provided may be changed. For example, if other users exist around the common entrance, the notification message may operate to be provided to the user terminal 200 possessed by the authorizer in the form of a short messaging service (SMS), an app push notification, or the like.

So far, a method for providing a notification service according to an embodiment of the present invention has been described with reference to FIGS. 8 and 9 . According to the above description, various notification messages for a corresponding user, such as un-received parcel information, can be provided through the lobby phone 100, and thus the user's convenience can be improved. Hereinafter, a method for controlling a target door in consideration of a user's moving direction according to an embodiment of the present invention will be described with reference to FIG. 10 .

10 is a view for explaining a method of accurately controlling a target door in consideration of a user's moving direction according to an embodiment of the present invention.

According to an embodiment of the present invention, as shown in FIG. 10 , a plurality of beacon devices 100 , 630 , and 650 are installed at different positions adjacent to the target door. In addition, a beacon message is broadcast from each of the beacon devices 100 , 630 , and 650 . In this case, the beacon message includes identification information for each beacon device 100 , 630 , and 650 .

In response to the reception of the beacon message, the user terminal 200 transmits a response message further including signal strength information of each beacon message and identification information of the beacon devices 100 , 630 , and 650 to the server 300 .

In response to the reception of the response message, the server 300 determines the moving direction of the user using signal strength information of the beacon messages transmitted from each of the plurality of beacon devices 100 , 630 , and 650 . More precisely, the server 300 determines the movement direction of the user by using the degree of change in the signal strength information of each beacon message and the positions of the beacon devices 100 , 630 , and 650 identified through the identification information. In this case, the positions of the beacon devices 100 , 630 , and 650 may be preset information. A method of determining a moving direction by receiving a plurality of signals is a matter that can be clearly understood by those skilled in the art, and a description thereof will be omitted.

In the present embodiment, the server 300 controls the target door using the determined moving direction of the user. For example, even if the user is an authorized person whose access authority is verified, if the moving direction does not accurately face the target door, the server 300 may not open the target door. Alternatively, the server 300 may transmit the door opening message to the lobby phone 100 when the moving direction of the authorized person accurately faces the target door. According to the present embodiment, since the opening and closing timing of the target door can be more accurately determined, the accuracy of access control can be improved.

Meanwhile, according to another embodiment of the present invention, the server 300 may control the target door by determining the moving speed of the user. Specifically, the server 300 may determine the moving speed of the user using the first signal strength information received at the first time point and the second signal strength information received at the second time point from the user terminal 200 . Also, the server 300 may determine the opening or closing time of the target door by determining the moving speed. For example, when an authorized person approaches the target door quickly, the server 300 may provide a safe access service by allowing the target door to be opened quickly. As another example, when an authorized person approaches the target door slowly, the server 300 may minimize the opening time of the target door by allowing the target door to be opened after a certain point in time. Accordingly, the safety of the facility in which the access system is constructed may be improved.

So far, a method of controlling the target door using the moving direction and/or moving speed of the user has been described with reference to FIG. 10 . Hereinafter, a method of controlling a target door using a user type according to an embodiment of the present invention will be described with reference to FIG. 11 .

11 is a flowchart of a method of determining an opening time of a target door using a user type according to an embodiment of the present invention.

Referring to FIG. 11 , in step S210 , the server 300 determines the type information of the user who has the user terminal 200 . In this case, the type information may be defined using various factors such as, for example, demographic information, whether or not to ride a vehicle, whether or not to possess a wheelchair, which may vary according to embodiments.

In an embodiment, the type information of the user may be determined using the received second identification information of the user. More specifically, the user registers his/her user type information through a dedicated app mounted on the user terminal 200, and the server 300 uses the second identification information to query the type information of the previously registered user. User type information can be obtained.

In an embodiment, the user's type information may be determined using image analysis information for a surveillance image obtained from CCTV. In this case, the CCTV means a CCTV installed adjacent to the target door. For example, the server 300 may obtain demographic information of a user through image analysis of a surveillance image, and determine user type information using the obtained demographic information.

In step S230 , the server 300 determines the opening time of the target door using the user type information determined in step S210 . For example, when the user is a user in a wheelchair, the opening time of the target door may be determined as a relatively long time. As another example, even when the user is an elderly person, the opening time of the target door may be determined to be a relatively long time. This is because it may take a relatively long time for the user to complete entry through the target door.

In step S250 , the server 300 controls the target door to be opened for the opening time determined in step S230 .

So far, a method of determining the opening time of the target door using the user's type information has been described with reference to FIG. 11 . As described above, the opening time of the target door may vary according to the type of user. For example, in the case of a type of user that takes a lot of time until entry and exit is completed (eg, an elderly person, a user in a wheelchair, etc.), the user's safety may be secured by maintaining the opening time of the target door long. For another example, in the case of a type of user that takes a short time until entry and exit (e.g. a male in his twenties, etc.), the security of the facility may be improved by keeping the opening time of the target door short.

Meanwhile, according to an embodiment of the present invention, when a plurality of target doors are installed around the lobby phone, the target door to be controlled may be identified using the user's type information. For example, when a common front door and a parking lot entrance are installed around the lobby phone, the type of the user is determined depending on whether the vehicle is boarded, and in the case of the user riding in the vehicle, the parking lot entrance door may be identified as a control target. Whether or not to board the vehicle may be determined through, for example, analysis of CCTV surveillance images.

Hereinafter, with reference to FIG. 12 , a method of controlling a target door by further using a face recognition result according to an embodiment of the present invention will be described.

12 is a flowchart of a method of determining whether to open or close a target door by further using a user's face recognition result according to an embodiment of the present invention.

According to an embodiment of the present invention, additional verification as to whether the user possessing the user terminal 200 corresponds to the user indicated by the second identification information included in the response message may be performed through face recognition. Alternatively, even if a user does not possess the user terminal 200 , determination as to whether the user corresponds to an authorized person having access right may be performed through face recognition. Hereinafter, a process in which the face recognition is performed will be briefly described.

Referring to FIG. 12 , in step S310 , the server 300 acquires image information about the user. For example, surveillance image information about the user may be acquired through a CCTV installed adjacent to the target door. As another example, image information about the user may be acquired through the camera of the lobby phone installed adjacent to the target door.

In step S330, the server 300 performs face recognition for the user. For example, face recognition may be performed by matching a pre-stored face DB with a face image analyzed through a surveillance image.

In step S350, whether the target door is opened or closed is determined further using the face recognition result. For example, when the user indicated by the face recognition result (ie, the current owner of the user terminal 200) and the original owner of the user terminal 200 are different, the server 300 controls the target door to remain closed can do. For another example, even when the user does not possess the user terminal 200 , when it is determined as a user having access authority as a result of face recognition, the server 300 may control the target door to be opened.

According to the above-described embodiment, when the user terminal 200 is hijacked, access of unauthorized persons is restricted through face recognition, so that the security of the facility in which the access control system is constructed can be improved. In addition, even when the user terminal 200 is not carried, the target door can be automatically opened through face recognition, and thus user convenience can be improved.

Hereinafter, a method of determining whether to open or close the target door in consideration of an unauthorized person around the target door will be described with reference to FIG. 13 . In particular, FIG. 13 illustrates a case in which the authorized person 710 and the non-authorized person 730 exist together around the common entrance as an example.

Referring to FIG. 13 , in this embodiment, the server 300 determines whether or not an unauthorized person 730 without access authority exists around the target door, and uses the result of the determination to determine whether the target door is opened or closed. decide

In an embodiment, the existence of the unauthorized person may be determined using a comparison result between the number of different second identification information received for a preset time and the number of people present in the vicinity of the target door. For example, in the exemplary diagram shown in FIG. 13 , the number of different second identification information is “one” of identification information received from the terminal of the authorizer 710, and the number of people around the target door is “two people”. ", it can be determined that there is one unauthorized person 730.

The number of people present around the target door may be determined using a surveillance image acquired through a CCTV 610 installed adjacent to the target door as shown in FIG. 13 . Alternatively, it may be determined using a proximity sensor installed adjacent to the target door. A method of counting the number of people from a surveillance image and/or a method of determining the number of people using a proximity sensor is already obvious to those skilled in the art, so a description thereof will be omitted.

In an embodiment, whether the unauthorized person exists may be determined using a face recognition result. For example, when face recognition is performed using a surveillance image obtained through a CCTV 610 installed adjacent to the target door, and there is a user 730 who cannot be recognized, it is determined that an unauthorized person exists. can

In this embodiment, the server 300 may decide to keep the target door closed in response to determining that an unauthorized person is present. Accordingly, the access of unauthorized persons following the authorized person may be restricted, and the security of the facility may be improved.

Meanwhile, according to an embodiment of the present invention, even when an unauthorized person exists, the server 300 may operate to open the target door in response to separate access request information received from the user terminal 200 .

In this case, the access request information may be any information that is automatically transmitted to the server 300 as the user terminal 200 recognizes a predetermined user behavior. The predetermined user action may be variously defined as, for example, clicking the screen of the user terminal 200, shaking the user terminal 200 up/down, left/right, etc., and any recognizable action It is free even if it is designated as an action.

For reference, the user may be implemented to register a user action that triggers the transmission operation of the access request information by using a dedicated app installed in the user terminal 200 . According to the present embodiment, when a user who does not have a user terminal, a friend of the authorized person, a delivery driver, etc. exist around the common entrance, the authorized person performs only the most convenient action set by the authorized person so that the target door installed in the common entrance is installed. can be made open. Accordingly, user convenience and security for facilities can be secured at the same time.
