Abstract
A contents databasememorizes the discriminating information for discriminating contents and the temporal information as to the time of content duplication associated with the discriminating information. A recording programacquires the discriminating information of contents to be duplicated and duplicates the contents in association with the acquired discriminating information and with the temporal information memorized in the contents database. This substantially prohibits duplication in large quantities without significantly impairing the interests of a user.
