%X Based on chaotic sequences and discrete fractional Fourier transform, a digital watermarking algorithm is proposed, and its resistance to attacks is simulated. The results show that the algorithm is easy to realize, and is robust to the attacks from JPEG compression, noise perturbation and filtering.
