The technology of a digital watermarking that can embed copyright information in valuable images has come to be paid attention. Therefore, we propose a new digital watermarking method using the Smearing-Desmearing transformation and show the algorithm. The Smearing-Desmearing transformation is a new transformation that watermark information is spread on the whole of an image. In our method, we can easily calculate how much the method degrades the quality of the watermarked image from embedded watermark energy.
