【Abstract】 A digital watermarking algorithm based on image compression standard JPEG and human visual system is proposed, which embeds data in compression field. In order to improve the robustness, a new method of double bits is also proposed. Experimental results show that the proposed watermarking scheme is very robust against cutting, filtering, noise and compression, especially JPEG compression.更多还原
