Abstract
In an apparatus for embedding an electronic watermark, a determining unit determines whether a specified area that is specified is present in image data. A text/non-text detecting unit detects a text area and a non-text area in the image. The specified area is at least one of the text area and the non-text area as an area. The embedding unit embeds an electronic watermark into the specified area.
