Electronic watermark system

Abstract

An electronic watermark system invisibly embeds watermark information into original image data and the watermarked image data is transferred to a first medium (504, 604). At the same time, the embedded watermark information is transferred to a second medium (505, 605). When a medium questioned is found, its watermark information can be easily identified by searching the second medium. Alternatively, the watermarked image data and the embedded watermark information are transferred to different storage areas (705, 706) of the same medium (704), respectively.
