Abstract
The present invention improves user-friendliness and protect content with increased reliability when judging whether network devices belong to the same home network. While the connection to a network is established, each network device uses a peripheral device information collection unit to collect peripheral device information indicating which ones of devices are connected to the network, and store the collected information in a peripheral device information storage unit as home network information. When the belonging of a remote device is to be judged, the home network information stored in the remote device is received. A peripheral device information collation unit collates the received home network information with the home network information stored in the peripheral device information storage unit to judge whether the remote device belongs to the same network as the local device.
