摘要：User location information provides additional layer of security to a system. The location information of a user is an important attribute that can be used in authentication systems. Legitimate user has to be physically resides within a restricted area to gain access. With the growth of wireless communication technologies that use radio waves, determination of user location for indoor environment is very challenging. Radio signal can penetrate walls; thus it is not easy to verify location information within a restricted area as small as a room. In this paper, we propose a location-based authentication system that is cost-effective and user friendly. The proposed system uses common infrastructure such as LED lightbulb and smartphone. To verify the location of the user, visible light communication technology via the LED lightbulb is used.
