Abstract
In a data processing apparatus and method, watermark information embedded in data can be detected even if the data is subjected to various processing. The apparatus includes a processor for processing data, an output unit for outputting the data processed by the processor, a measurement unit for measuring and determining a processing record of the processed data, and a controller for controlling the operation of the processor based on the processing record.
Claims32
