Abstract:
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.
