1 is a diagram illustrating an ordering system in an apartment building using a face image according to an embodiment of the disclosed technology. Referring to Figure 1, the system is composed of a management server 110 and a plurality of devices. The management server forms an internal network with a plurality of devices. In addition, terminals provided in stores of a plurality of small business owners around the apartment house are connected through an external network. That is, the order management server 110 serves to transmit a user's order request from a specific device inside the apartment house to a small business terminal outside the apartment house, and processes the order based on the user's face image. The order management server 110 may receive order information from a specific device among a plurality of devices through an internal network. Hereinafter, a specific device that transmits order information is referred to as a first device.

A plurality of devices are installed in each area inside the apartment house and receive order information according to the user's request. Here, the order information includes the type of service ordered by the user, the time at which the service was requested, and details of the service. In one embodiment, the type of service may be food delivery, a hair salon reservation, a request to visit a laundromat, etc., and the time requested for the service may be the time the food is delivered, the time to visit the hair salon, or the time the owner of the laundromat wants to visit. there is. In addition, the details of the service may be for a specific menu in the case of food delivery, and in the case of a hair salon reservation, it may be specific items such as cut, perm, dyeing, etc. Request for visiting a laundry or collection request for general laundry It may be specific items such as recognition, dry cleaning, or repair. The order information includes such information, and the user may input the order information through a first device among a plurality of devices.

The plurality of devices described above are installed in each area of the apartment house. For example, it may be installed in each household of the apartment house, the entrance door of the apartment house, the entrance door for each complex of the apartment house, the inside of the elevator of the apartment house, and each community center of the apartment house. As shown in FIG. 1, Area-1 may be the area where the entrance door of the apartment house is located, Area-2 may be the area where the door of the complex 1 is located, and Area 3 (Area-3) It may be the area where the entrance door of the 2nd complex is located. In addition to the above-mentioned zone, the devices may be installed anywhere inside the apartment house.

Meanwhile, a plurality of devices may be installed as a separate device for each zone or may be included in an existing device in the form of a program. For example, a plurality of devices may be installed in the form of separate kiosks or terminals in each household of an apartment house, an entrance door of an apartment house, an entrance door for each complex of an apartment house, inside an elevator of an apartment house, and a community center of the apartment house. Alternatively, a device installed in each household of an apartment house can be implemented as a program included in a door phone, and a device installed at the front door of an apartment house or an entrance door of a complex can be implemented as a program included in a device that controls gate opening and closing. Also, a device installed in an elevator of an apartment building or a community center may be a device in the form of a kiosk installed on a wall or standing, or may be implemented in the form of a program included in an existing device.

Meanwhile, the user may input order information through a device closest to his/her location. For example, if you are at home, you may input order information using a device installed in your household, or if you are in a community center, you may input order information using a device installed in the center. That is, the user can freely request an order at any place within the apartment house.

Meanwhile, when the order management server 110 receives the order information, it transmits a control signal to the first device to take a user's face image. This is to identify whether the user is one of the residents of the apartment house. The order management server performs a service of receiving requests for orders only from residents of apartment houses and delivering them to nearby small businesses. In the conventional case, in order to prove that you are a resident, you have to enter a password or go through an authentication procedure that requires a separate input, which causes inconvenience to the user. It is possible to receive To this end, cameras are provided in a plurality of devices, and the cameras can be driven according to a control signal from the order management server 110 . The order management server 110 transmits a control signal to the first device to photograph the user's face image.

On the other hand, the photographed face image is used to compare with the resident information previously stored by the order management server 110. The order management server 110 stores resident information for each of a plurality of residents in a database. In the resident information, not only the resident's face image, but also information such as the building, number, family relationship, and contact information may be stored together. The order management server 110 matches a plurality of face images included in a plurality of resident information with a user's face image.

Meanwhile, according to the matching result, the user may be identified as a resident or a non-resident. The order management server 110 identifies the user as a resident when one of the face images of a plurality of residents matches the face image of the user. In this case, the received order information is transmitted to the small business owner. And if there is no matching face image, the user is identified as a non-resident. In this case, a control signal for resident registration may be transmitted to the first device. The first device may drive a camera according to each control signal to capture a user's face image or output an interface for resident registration.

Meanwhile, the order management server 110 may process payment according to order information using the user's face image. As an embodiment, the order management server may check a user's online account among online accounts for a plurality of users and pay a cost according to the order information using the balance in the account. That is, payment can be made using the user's face image without using a password or authentication code input by the user. The order management server is connected to the cost management server 120 that stores information on a plurality of online accounts. Like a plurality of devices, the cost management server 120 may be one node on the internal network of an apartment building. When the order management server 110 identifies the user as a resident according to the matching result, the cost management server 120 may request payment according to the order information to the cost management server 120 .

Meanwhile, the cost management server 120 may store an online account for each resident. The cost management server 120 may use the balance of each user's online account to settle management costs for each user. That is, it is possible to settle the cost of using the service ordered by the user and the management fee together. Residents of apartment houses can open their own online accounts in advance and store them in the cost management server 120, and can process payments using face images whenever payment occurs.

On the other hand, when the order management server confirms that the order information is the resident's order information, it transmits the order information to the terminal of the first small business store according to the order information among the plurality of terminals each provided in the stores of the plurality of small business owners outside the apartment house connected to the external network. convey Stores of a plurality of small business owners are stores located outside the apartment house, and each store is provided with terminals capable of receiving order information. Terminals provided in each store may use terminals such as smartphones, tablets, general PCs, and laptops. The order management server transmits order information to a store terminal of a specific small business according to the type of service included in the order information. For example, terminal a in FIG. 1 may be a terminal of a restaurant, terminal b may be a terminal of a beauty salon, and terminal c may be a terminal of a laundry. The order management server may identify which store to send the order according to the information included in the order information. For example, order information may be transmitted to a store terminal of a specific small business according to the type of service included in the order information. Hereinafter, the small business owner receiving the order information is referred to as the first small business owner.

Meanwhile, the order management server may transmit the face image of the user requesting the order information together with the order information to the terminal of the first small business owner. That is, the first small business owner can identify who the person who placed the order is, and when visiting the user's residence, the service can be accurately provided without being confused with others.

The first small business owner may prepare a service that can be provided according to the order information transmitted to the terminal. For example, if the user's order information relates to food delivery, the requested menu may be cooked and packaged. The first small business owner may visit the apartment complex and request access in order to provide the prepared service.

Meanwhile, similar to the process of receiving the user's order information, a face image may be taken even when the first small business owner requests access. The first small business owner may request access through a second device among a plurality of devices, and the second device may take a face image of the first small business owner according to a control signal from the order management server. The captured image is transmitted to the order management server. When the order management server receives the face image of the first small business owner, it transmits it to the first device. Similar to the case of forwarding the order information to the first small business owner, the user requesting the order may check the face image of the first small business owner transmitted to the first device. Therefore, the service according to the order information can be received without confusing the first small business owner who is scheduled to visit soon with another person.

Meanwhile, the order management server 110 may output route information on the screen of the second device so that the first small business owner can grasp the exact destination. The route information includes a route from the location of the second device to the user's residence. If the user inputs the order information to receive service at the location of the device for which the order information is input, a route from the location of the second device to the first device may be output as route information.

Meanwhile, the order management server includes a resident database for storing resident information on a plurality of residents and a visitor database for storing visitor information on a plurality of visitors. The user's face image is stored in the resident database. And the visitor database stores the face image of the first small business owner. The order management server can store the face images of residents and visitors separately in this way, and can set a long storage period for the face images stored in the visitor database for safety in the apartment house.

2 is a flowchart of a method for ordering in an apartment building using a face image according to an embodiment of the disclosed technology. Referring to FIG. 2, the ordering method in the apartment house includes the step 210 of the order management server receiving the user's order information input to the first device among the plurality of devices installed in each area inside the apartment house, the order management server Step 220 of sending a control signal to the first device to photograph a user's face image, receiving the user's face image, and matching it with a plurality of pre-stored resident information (220). Sending order information to a store terminal of a first small business according to the order information among store terminals of small business owners of (230), receiving an access request from a first small business from a second device among a plurality of devices (240) and transmitting, by the order management server, route information from the location of the second device to the residence of the user to the second device (250).

In step 210, the order management server receives order information of the user from a first device among a plurality of devices connected to the network. The first device is a device installed in a specific area in an apartment building, and may be a device installed in a user's residence or a device installed in a community center. The user may input order information according to the user interface output on the screen of the device. The order information includes the type of service ordered by the user, the time at which the service was requested, and details of the service.

In step 220, the order management server transmits a control signal to the first device to photograph the user's face image. A camera is installed in the first device and the plurality of devices, and the camera can be driven according to a control signal transmitted from the order management server to capture a user's face image. The first device transmits the captured image to the order management server through the network. The order management server matches the transmitted face image with a plurality of face images included in a plurality of pre-stored resident information. If there is a matching face image, the order management server may identify the user as one of the residents as a matching result. If a matching face image does not exist, it may be identified as a non-resident. If the user is identified as a non-resident, the user may be a resident who has not registered in advance, so the process for resident registration can be guided. For example, a control signal may be transmitted to the first device to output an interface for resident registration.

In step 230, the order management server delivers the order information to the store terminal of the first small business owner matching the order information of the user among a plurality of small business owners around the apartment house. The order management server may transmit order information to a terminal provided in the store of the first small business owner through the Internet network. Here, the store terminal may use a POS terminal in the store or a terminal provided separately to receive online order information. The order management server may determine the type of service included in the order information and transmit the order information to a store of a first small business among a plurality of small business owners. Of course, in the process of inputting order information, by entering the store address or trade name of a specific small business owner, it is possible to determine which store terminal to deliver the order information to. In addition, order errors can be prevented by transmitting the face image of the user requesting order information together.

Steps 210 to 230 described above are a process of delivering order information, and steps 240 and 250 below correspond to a process in which the first small business owner provides a service according to the order information to the user.

In step 240, the order management server receives an access request of the first small business from a second device among a plurality of devices. The first small business owner may visit the user by preparing a service according to the order information. More specifically, it may visit the user's residence to provide ordered food, products, or services. In general, multi-unit dwellings such as apartments and officetels are often prevented from entering outsiders to enhance security. Since the first small business owner also corresponds to an outsider, access can be requested through the device in order to enter the apartment house. For example, access can be requested by pressing the call bell of the second device installed at the entrance of the apartment.

Meanwhile, when the access request is received, the order management server may check whether the first small business has visited according to the order information. For example, if the user's order information is stored for a certain period of time and a request for access from the first small business owner is received, an interface for confirming the order information may be output to the second device, which is a device at a location at which the first small business owner requested access. Access of the first small business may be allowed by scanning the receipt and comparing with stored order information, or by comparing pre-stored resident information on a user with visitor information input by the first small business owner. Alternatively, information on the user's face image received together with the order information may be transmitted to the second device, and the order management server may allow access based on this. When the order management server receives the order information transmitted by the first small business owner and the user's face image, it is possible to identify whether the first small business owner is an outsider visiting to provide services by matching the pre-stored order information and face image. By following this process, malicious orders can be prevented or invalid orders can be checked.

Meanwhile, the second device may take a face image of the first small business owner under the control of the order management server and transmit it to the order management server. The order management server may transmit the face image of the first small business owner to the user's device to check the face of the person providing the service requested by the server. For example, when ordering food, the face of the person delivering the food may be checked in advance so as not to be confused with another resident's order.

In step 250, the order management server transmits route information for the visit to the second device when confirming that the first small business owner is a visitor for providing services according to the order information. Route information refers to a route from the location of the second device to the user's residence. The first small business owner can accurately move to the user's location based on route information output on the screen of the second device.

3 is a block diagram of an order management server according to another embodiment of the disclosed technology. Referring to FIG. 3 , the order management server 300 includes a communication device 310 , a storage device 320 and an arithmetic device 330 .

The communication device 310 forms a network with a plurality of devices and receives user order information through the network. The communication device may form an internal network of an apartment house in a wired or wireless manner. The communication device may be implemented as a TCP IP-based device connected through a general Internet line.

The storage device 320 stores a plurality of resident information. Resident information includes face images of each resident. The storage device 320 may be implemented as a memory of an order management server. For example, it may be implemented as a mass information storage device such as HDD or SSD.

The arithmetic unit 330 matches a plurality of face images included in a plurality of resident information with a user's face image. The computing device may be implemented as a CPU or AP of the order management server. The arithmetic device 330 may determine whether the user is a resident by checking whether any of the previously stored face images of the resident information matches the face image of the user. When it is confirmed that the user is a resident, the arithmetic device 330 transmits the order information to the store terminal of the small business through the communication device 310 .

Meanwhile, the space order management server 300 described above may be implemented as a program (or application) including an executable algorithm that may be executed on a device such as a computer. For example, it may be a program that is installed in a device such as a computer that already exists in a management office or computer room of an apartment building or is executed on such a computer. The program may be stored and provided in a temporary or non-transitory computer readable medium.

A non-transitory readable medium is not a medium that stores data for a short moment, such as a register, cache, or memory, but a medium that stores data semi-permanently and can be read by a device. Specifically, the various applications or programs described above are CD, DVD, hard disk, Blu-ray disk, USB, memory card, ROM (read-only memory), PROM (programmable read only memory), EPROM (Erasable PROM, EPROM) Alternatively, it may be stored and provided in a non-transitory readable medium such as EEPROM (Electrically EPROM) or flash memory.

Temporary readable media include static RAM (SRAM), dynamic RAM (DRAM), synchronous DRAM (SDRAM), double data rate SDRAM (DDR SDRAM), and enhanced SDRAM (Enhanced SDRAM). SDRAM, ESDRAM), Synchronous DRAM (Synclink DRAM, SLDRAM) and Direct Rambus RAM (DRRAM).

4 is a diagram illustrating a device provided in an apartment house. Referring to FIG. 4 , a plurality of devices installed in each area of an apartment house are provided with displays, and an interface for inputting order information or capturing a face image may be output to a specific area of the display. For example, an interface for inputting order information may be output in area 401, and an interface for photographing a face image may be output in area 402. In area 401, a plurality of types of services to be ordered may be output, and the user may select one of them. In addition, by tapping or swiping the display or selecting a keypad area output on the display, the service request time can be set. Further, by selecting one or more of the lists for a plurality of details, details of a service to be ordered may be input. When the input of order information is completed in area 401, a face image may be captured according to an interface output in area 402. The device may use an additional means for accurate photographing so that the user's face image can be matched with the face image of pre-stored resident information. For example, a guide voice for accurate photographing may be output using a speaker or a guide message may be output on a display.

Meanwhile, as shown in FIG. 4 , since an image captured by a camera is output in an area 402 , the user can self-confirm whether or not the user's face is accurately captured. The actual camera may be provided at a specific location of the device, and a face image may be captured using a plurality of cameras as needed. For example, two left and right stereo cameras may be used to identify whether a real user is being photographed.

5 is a diagram illustrating transmission of route information. The order management server may transmit route information from the second device installed at the location of the small business owner requesting access to the residence of a resident to receive service to the second device.

Meanwhile, some devices among a plurality of devices may also serve to control opening and closing of the gate, and the order management server may control opening and closing of the gate by transmitting a control signal to these devices. For example, if the user is a resident living in Complex 2, the order management server may transmit route information to the screen of the device where the small business is located and transmit a control signal for opening and closing the gate to a device installed at the door of Complex 2. Of course, since the device installed at the door of Complex 1 or the community center did not receive the control signal, small business owners cannot enter and exit. When the small business owner approaches the door of Complex 2, the device can open the gate. The gate is provided with a means for recognizing a person's approach, such as an infrared sensor, and the gate can be opened only when a control signal is received from the order management server. If a small business owner misunderstands and approaches the gate installed at the entrance of complex 1, the gate may not be opened because the control signal is not received from the order management server even if the infrared sensor detects human access. In this way, by delivering order information of residents using face images and providing route information to small business owners who visit to provide services, various convenient services for residents can be provided and there is an effect of activating local commercial districts around apartment houses.

6 is a diagram illustrating a process of making a payment using a face image. Referring to FIG. 6 , a resident in an apartment house may perform payment based on a face image according to the following steps.

In step 610, the user requests an order using the nearest device. The user may request an order by inputting order information using the first device.

In step 620, the first device captures a face image to be used for payment of the user. The first device may capture a user's face image according to a control signal transmitted from the order management server. Of course, when an order is requested, a face image may be photographed by automatically driving a camera without receiving a separate control signal.

In step 630, the first device transmits the face image to the order management server connected to the network. Considering the security issue of biometric information, the first device may encrypt and transmit the face image in a form decipherable by the order management device.

In step 640, the order management server may identify whether the user is a resident or not based on the transmitted face image. For example, if there is a match among a plurality of face images included in a plurality of resident information stored in the resident database, the user may be identified as a resident. If the user is identified in this way, the order management server may request payment from the cost management server. For example, the order management server may extract feature information included in the face image and transmit the order information and feature information together to the cost management server. Of course, the process of extracting the feature information of the face image may be performed in the cost management server.

In step 650, the cost management server performs payment based on the user's order information and feature information extracted from the face image. The expense management server may directly process the process for payment of expenses or may request payment to a financial service provider server such as a credit card company. In the case of directly handling the payment process, the user's online account already provided for payment of the management fee can be used to deduct the cost associated with the payment. Of course, when the balance is lower than the payment cost, a notification of payment failure may be transmitted to the first device to notify the user. The cost management server may store the feature information extracted from the user's face image in advance as an authentication means for payment, and may process the payment by comparing it with the transmitted feature information. The cost management server transmits details about the success or failure of the payment to the order management server.

In step 660, the order management server transmits the order information to the store terminal of the small business according to the transmitted payment details. As described above, the store terminal of the small business owner can use a terminal installed in the store or a smartphone of the small business owner. The order management server includes a database that stores information about a plurality of small business owners around the apartment house. Then, the order information is transmitted to a specific small business matching the order information in the small business database or to a terminal of a specific small business designated according to the order information. According to this process, the user can process the payment according to the order using the face image without going through a separate input process or authentication process for payment.

The method and system for ordering in an apartment building using a facial image according to an embodiment of the disclosed technology have been described with reference to the embodiment shown in the drawings to aid understanding, but this is only exemplary, and those skilled in the art Those who grow up will understand that various modifications and other equivalent embodiments are possible from this. Therefore, the true technical scope of protection of the disclosed technology should be defined by the appended claims.
