Abstract
A data distribution device distributes a plurality of sets of data to a user one set of data at a time intermittently at intervals. Every time derived data obtained using the data are generated by the user, a registration device for user registers derived data generation history information indicating that the derived data are generated in a history management database. A derived data generation history information monitor examines whether or not derived data generation history information is registered in the history management database at a predetermined timing and, when no derived data generation history information is registered, suspends subsequent distribution of the data from the data distributor to the user.
