| 1. An information-processing device comprising:
a first interface configured to transmit content to a first communication unit through a network;
a second interface for a short-range communication and configured to receive a first unique identification allocated to the
first communication unit from a second communication unit and transmit a second unique identification allocated to the information-processing
device to the second communication unit;
an identification list configured to store at least one unique identification which is transmitted from the second communication
unit through the second interface; and
an identification judgment unit configured to determine whether the first unique identification received through the first
interface is stored in the identification list;
wherein, when a unique identification of another communication unit is stored in the identification list, the another communication
unit has to be located within the range of the short-range communication and has performed mutual authentication with the
second communication unit,
wherein when the identification judgment unit determines that the unique identification of the first communication unit is
stored in the identification list, the first interface allows the content to be transmitted to the first communication unit.
