Abstract

We proposes a multipurpose image watermarking algorithm which embeds visible watermark and invisible watermark into an original image. This is to satisfy the two characteristics of copyright notification of the visible watermark and copyright protection of the invisible watermark. The visible watermark's transparency is highlighted to be easily identified in contrast to the original image and the invisible watermark is embedded in a spatial domain.
