摘要

A robust color image watermark scheme using kinoform is proposed. The kinoform has relatively less information than regular computer-generated hologram (CGH) as a watermark image embedded in a color Lena. The kinoform is transformed into a non-cascade iterative encrypted kinoform watermark with non-cascade phase retrieve algorithm and random fractional Fourier transform. This kinoform watermark is embedded in the color cover image, which can be extracted with the only right phase key and right fractional order, and reconstructed to represent original watermark image. In color image, our experimental results have been shown in high security, good imperceptibly, and robustness to resist attacks, such as noise, compression, cropping and so on.
