Abstract
Abstract An image data encoding system has a discrete cosine transformer for discrete cosine transforming the original image, an electronic watermark data embedding circuit for embedding the electronic watermark data in the data that has been transformed by the discrete cosine transformer, and a data selector for selecting the output signal of the discrete cosine transformer or the output signal of the electronic watermark data embedding circuit. Another image data encoding system has an electronic watermark embedding circuit for embedding electronic watermark data selected from a plurality of types of electronic watermark data to the digital image data, wherein at least one of the plurality of types of electronic watermark data is predetermined electronic watermark data that does not affect the digital image data even if the electronic watermark data is embedded in the digital image data.
