KR-102961977-B1 - ACCESS CONTROL APPARATUS AND METHOD USING USER TERMINAL

Abstract

An access control device and an access control method using a user terminal are disclosed. An access control device capable of short-range communication with a user terminal according to one embodiment of the present invention comprises: a first communication unit that transmits a device identification code to the user terminal; a second communication unit that receives an authentication code from the user terminal; and a control unit that opens and closes a door after authenticating the authentication code. The authentication code is generated by an authentication server connected to the user terminal via a network in response to a request from the user terminal and transmitted to the user terminal.

Description

Access control apparatus and access control method using user terminal The present invention relates to an access control device and an access control method using a user terminal. More specifically, the invention relates to an access control device and an access control method in which the access control device receives an authentication code generated by an authentication server from a user terminal connected to an authentication server via a network and authenticates it to open an access door. In modern society, the importance of access control is increasing day by day due to user safety and security concerns in multi-unit dwellings such as apartments and officetels, accommodations such as hotels, and research facilities of the state or corporations. Furthermore, with the growth of the delivery and transportation industries, there is a growing trend of increased frequency and necessity for one-time visits by employees in these sectors. However, most currently commercialized access control systems unlock doors using methods such as password entry, card key tagging, or intercom calling to control access. Therefore, if passwords are used to facilitate access to the aforementioned facilities, there is a risk of password exposure to an unspecified number of people, as access control devices are typically installed in public places. Furthermore, using card keys may result in the inconvenience of having to carry the key at all times, as well as issues regarding card loss and the additional costs incurred due to such loss; conversely, using intercoms may lead to restricted access due to the absence of an administrator.
