Abstract
A terminal (140) attaches a client ID and a whole or a part of LT to a backup request and sends them to a right management server (710). A right management server (710) verifies the client ID to see when the entity originating the request is an registered user, and it also verifies data identification ID on the LT to see when right data is the one issued by the server for the registered user, and then performs backup for the right data when the right data is the one issued by the server. The terminal (140) attaches the client ID to a restoration request and sends them to the right management server (710). The right management server (710) checks a user ID from the client ID, and then restores the right data to the terminal (140), which is backed-up in association with the user ID.
