摘要:
A secret information setting device includes a generation instruction receiving unit receiving a secret information generation instruction from a user; a secret information generation unit generating the secret information in response to the secret information generation instruction received with the generation instruction receiving unit; a secret information storage unit storing the secret information generated by the secret information generation unit; a secret information transfer unit transferring the secret information stored in the secret information storage unit to the plurality of appliances; and a secret information deleting unit deleting the secret information stored in the secret information storage unit when a predetermined condition is satisfied.
摘要:
To provide, without requiring a user to have special knowledge or to pay a high cost, a communication apparatus which enables detection of an apparatus present on a different network in a router multistage network comprising a plurality of routers. When a communication apparatus (101) cannot detect, on a network thereof, a desired apparatus, the communication apparatus requests a connection support server (001) securing communication paths with all the apparatuses on a home network, to relay an apparatus detection request. The connection support server (001) transfers the request to relay the apparatus detection request, to an arbitrary apparatus belonging to a different network from the network to which the communication apparatus (101) belongs, and the arbitrary apparatus, by proxy, performs an apparatus detection, and transfers information about a detected apparatus to the connection support server (001). By obtaining the information from the connection support server (001), the communication apparatus (101) detects the apparatus on the different network.

A low cost communication apparatus enables detection of an apparatus present on a different network in a router multistage network having a plurality of routers. When a communication apparatus cannot detect, on a network thereof, a desired apparatus, the communication apparatus requests a connection support server securing communication paths with all the apparatuses on a home network, to relay an apparatus detection request. The connection support server transfers the request to relay the apparatus detection request, to an arbitrary apparatus belonging to a different network from the network to which the communication apparatus belongs, and the arbitrary apparatus, by proxy, performs an apparatus detection, and transfers information about a detected apparatus to the connection support server. By obtaining the information from the connection support server, the communication apparatus detects the apparatus on the different network.
