Abstract
Provided is a network system which is capable of smooth remote control of appliances in a household while improving the security. A household server for controlling home appliances and an external server for mediating between the household server and a user terminal are set on an Internet. The household server gives a right to access only to the external server that is registered in advance. When accessed by the user terminal, the external server performs user authentication and, if the access is authenticated as from an authorized user, specifies which household server is to be used by the user, and makes an access request to the corresponding server. The household server checks whether the access request is valid or not and, when the access request is found as a result to be valid, allows the user terminal to input a control instruction through the intermediation of the external server.
