Information-processing device
First Claim
1. An information-processing device comprising:
- a first interface configured to transmit content to a first communication unit through a network;
a second interface 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 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 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.

Abstract
An information-processing device includes a first interface configured to transmit content to a first communication unit through a network, a second interface 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 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 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.
