Abstract:
1. A visible light communication system comprising: a visible light communication device configured to transmit at least one piece of unique ID information by visible light communication; a communication terminal assigned with unique terminal identification information, and configured to receive the at least one piece of unique ID information by the visible light communication; a first server configured to memorize the unique terminal identification information assigned to the communication terminal, and to perform wireless communication through a medium of an electric wave with the communication terminal; and at least one second server assigned with unique server identification information, and configured to memorize service information corresponding to the at least one piece of unique ID information, and to perform wireless communication through another medium of another electric wave with the communication terminal, wherein the communication terminal comprises: a communication module configured to perform the visible light communication and the wireless communication; and a control module configured to memorize the unique server identification information, and to provide a service to a user, the service corresponding to the service information, wherein the first server is configured to memorize the unique server identification information assigned to the at least one second server, and to authenticate the communication terminal and the at least one second server, when the unique terminal identification information and the unique server identification information that are received from the communication terminal match the unique terminal identification information and the unique server identification information that are memorized in the first server, respectively, wherein the communication module is configured to transmit the at least one piece of unique ID information received from the visible light communication device, the unique server identification information received from the control module, and personal information included in the communication terminal, to the first server by the wireless communication, after the communication terminal is authenticated by the first server through the unique terminal identification information, wherein the first server is configured to memorize the personal information, and when the at least one piece of unique ID information, the unique server identification information, and the personal information that are received from the communication module by the wireless communication match the at least one piece of unique ID information, the unique server identification information, and the personal information that are memorized in the first server, respectively, the first server is configured to generate an authentication code, and transmit the authentication code and the unique terminal identification information to the communication module and the at least one second server by the wireless communication, wherein the communication module is configured to receive the authentication code transmitted by the first server, and then to transmit the at least one piece of unique ID information and the unique terminal identification information to the at least one second server by the wireless communication, wherein the at least one second server is configured to reply the authentication code and the service information to the communication module, when the unique terminal identification information received from the communication module matches the unique terminal identification information received from the first server, and wherein the communication module is configured to output the service information received from the at least one second server, to the control module, when the authentication code received from the first server matches the authentication code received from the at least one second server.
