摘要：
A data processing circuit and method which can process content data in an enhanced efficiency is disclosed. A right information processing section produces, based on utilization right information which indicates a utilization right of content data, key data to be used for a data process of the content data and adds a use object of the key data for utilizing the content data to the produced key data to produce processing use information. A temporary storage section temporarily stores the processing use information. A data processing section compares control information supplied from the outside and the use object included in the processing use information temporarily stored in the temporary storage section and performs, in response to a result of the comparison, a data process for the content data using the key data included in the processing use information.
