The server may perform visitor authentication using, for example, unique information of the service provider. In this case, in the terminal of the service provider, for example, an App distributed from the server to provide a non-face-to-face service according to an embodiment may be installed. The service provider drives an app installed in the terminal and transmits its own information to the server, so that visitor authentication through the server is performed. The unique information of the service provider may include, for example, at least one of biometric information and a service digital ID of the service provider. The biometric information of the service provider may include, for example, an image of at least one of the service provider's face, fingerprint, iris, and vein, and a voice of the service provider, but is not limited thereto. As will be described in detail below, Digital ID (DID) is used in an identity authentication system based on blockchain technology, and allows users to directly control and manage their personal information such as their name and age. Digital ID can also be called 'distributed ID'.

The server controls the door lock to be opened and closed by reproducing information about the card key through the smart key provided to the service provider based on the success of the visitor authentication performed in step 230 (240). Here, 'reproducing information on the card key' may be understood to include an emulate operation of imitating or surrogate execution of information on the card key (more specifically, UID and data of the card key). . In addition, 'controlling the door lock to open and close' means that the server does not directly open and close the door lock, but indirectly controls the door lock to open and close by reproducing information about the card key through the smart key provided to the service provider. can

In step 240 , if the visitor authentication is successful, the server may download information about the card key stored in the secure cloud. The server may transmit information about the downloaded card key to the smart key provided to the service provider through the service provider's terminal so that the UID and data of the card key can be emulated through the smart key.

In this case, the information on the card key may be activated and played from the smart key when the service provider succeeds in visitor authentication, for example, and may be initialized from the smart key as the connection between the server and the terminal of the service provider is disconnected. In addition, the smart key is coupled to the terminal of the service provider, and may operate through interworking with the server. The smart key may be provided, for example, in the form of a Universal Serial Bus (USB) coupled to a terminal of a service provider, but is not limited thereto. The smart key may include, for example, a communication interface for communication with a door lock. The communication interface is, for example, Wi-Fi communication, Bluetooth communication, Zigbee communication, infrared communication, LTE communication, 5G communication, Z-wave communication, Ultra-Wide Band ; UWB) communication, and RFID (Radio Frequency IDentification) communication may include at least one.
