A novel transform-domain image watermark based on cepstrum analysis is proposed in this paper. A complex cepstrum-based scheme is developed to embed a gray-level image in the one-dimensional cepstrum components of the original image signal. Computer simulation results show that the proposed algorithm is imperceptible and is robust to most watermarking attacks, especially to image cropping, JPEG compression and multipliable noise.
