Abstract

In this paper we propose a scheme of watermarking which embeds into a color image a color watermark from the L*a*b* color space. The scheme resists geometric attacks (e.g., rotation, scaling, etc.,) and, within some limits, JPEG compression. The scheme uses a secret binary pattern to modify the chromatic distribution of the image.
