Abstract
A server is configured to manage second positional information, which shows a location of the lighting device, so that the second positional information is associated with the ID information of the lighting device. The server is configured to determine whether or not the ID information received from the receiving terminal is justifiable based on the second positional information, which corresponds to the ID information received from the receiving terminal, and the first positional information, which is received from the receiving terminal. The server is configured to reply, to the receiving terminal, the service information corresponding to the ID information received from the receiving terminal when determining that the ID information received from the receiving terminal is justifiable. The server is configured not to reply the service information to the receiving terminal when determining that the ID information received from the receiving terminal is not justifiable.
