    摘要： An electronic watermark embedding apparatus and an electronic watermark embedding method can severally deal with both of the resistance property of an electronic watermark and the prevention of image quality deterioration. Electronic watermark information of a high importance level is embedded in a component having a strong resistance property, and electronic watermark information of a low importance level is embedded in a component exerting little influence on an image quality. As a result, the electronic watermark information to be embedded in the component having a strong resistance property is limited to that of a high importance level. Moreover, the image quality deterioration can be suppressed in comparison with the case of embedding all pieces of information, and the electronic watermark information of low importance level is embedded in the component having a weak resistance property but exerting little influence on an image quality.
