Abstract
An object of the invention is to make it possible to move data that is coded and managed for copyright protection after evaluating an encryption key and permitting its movement based on a result of the evaluation, as well as to make it possible to copy data that is recorded in a server to a terminal apparatus and cause the terminal apparatus itself to reproduce the data and, where a terminal apparatus is connected to the server, render data on the server reproducible.
