摘　　要：提出了一种基于JPEG图像压缩标准和人类视觉系统的数字水印算法,在压缩域内嵌入水印.为了进一步增强水印算法的鲁棒性,又提出了双位嵌入法.实验结果表明,该算法对剪切、滤波、噪声和压缩,尤其是JPEG压缩,都有很好的鲁棒性.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.
