    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.

    摘要: A signal processing circuit and apparatus is disclosed which can prevent illegal utilization of content data with a higher degree of certainty. A hardware module controls utilization of content data based on right information of the content data. A nonvolatile memory stores a first check value for checking the compatibility of an apparatus identifier transferred from an apparatus in which the hardware module is incorporated and a second check value for checking the compatibility of the right information of the content data. The hardware module checks the compatibility of the transferred apparatus identifier based on the apparatus identifier and the first check value, checks the compatibility of the right information in response to the right information and the second check value and controls the utilization of the content data based on the right information in response to results of the checks.
