SECURITY COMMUNICATION APPARATUS USING VISIBLE LIGHT COMMUNICATION

摘要

A user terminal receives a security code signal by using visible light communication (VLC) in a section in which security is previously authenticated and connects a network by authenticating the security with the received security code signal. A light/security code transmission unit outputs each light signal to a plurality of sections and synthesizes the security code signal and the corresponding light signal of a predetermined security authentication section among the sections. A plurality of user terminals is selectively positioned in the sections; receives the light signal; and connects the network by authenticating the security code when the security code is extracted in the light signal. A network connection unit receives the security code from the user terminals and authenticates the security code. The network connection unit connects the corresponding user terminal of the authenticated security code to the network.
