Abstract

An authenticator displays identification information based on device addresses transmitted from terminals. A user selects a terminal among the terminals based on the displayed identification information. A device address of the selected terminal is transmitted to a service providing device, and then added to a registration list. When a service providing device receives a service request from a terminal, the service providing device provides a requested service to the terminal if the device address of the terminal is listed in the registration list.
