Abstract
It is unknown what information terminals and how many information terminals are connected to one contracted information terminal. Accordingly, contents licensed to use by only family members of one household may be used by other persons. In view of such a situation, it is necessary to create secure environments. The present invention manages subterminals registered in all main terminals in a subterminal management part of a host device, and confirms validity of registration and deregistration by contract-time personal authentication information managed in a main terminal contract management part. Thereby, contents can be delivered only to reliable home networks.
