Security of watermark was ensured by preprocessing watermark information through simulating the generation of Fourier transform holographic watermark encryption and by reconstruction of encrypted holographic watermark. The watermark was embedded based on transform domain in the DCT-DWT and the luminance component L of the uniform color space CIELab, which can improve the invisibility of the watermark; the algorithm using encrypted holographic has strong robust against cut attack, and belongs to the blind extraction of watermark technology. The experimental results showed that the embedded watermark image can meet the visual requirements, and also meet the objective evaluation criteria; the reconstructed watermark image is clear and the authenticity of images can be judged accurately.
