DIGITAL SYSTEM FOR USER AUTHENTICATION, AUTHENTICATION SYSTEM, AND PROVIDING METHOD THEREOF

摘要

Disclosed are a digital system for user authentication, an authentication system, and a providing method thereof. The method for providing the digital system for performing user authentication includes: a step in which the digital system receives user authentication request received from an authentication system; a step in which the digital system performs wireless local area network (WLAN) communication with a pair system in response to the reception; and a step in which the digital system transmits authentication information corresponding to identification information of the pair system received through the WLAN to the authentication system. If the transmitted authentication information corresponds to the identification information of the user authentication device registered in the authentication system, user authentication for a user of the digital system can succeed by the authentication system.
