| 摘 要： | 该文提出了一种新的有效的抗JPEG压缩的水印算法,对嵌入水印的图像做JPEG压缩,提取水印仍能保证很好的稳健性,并能抵抗一些常见的攻击。通过对图像做仿JPEG流程的处理,在DCT变换的直流系数上嵌入水印,对于各种常用的JPEG压缩量化因子,可以得到良好的水印嵌入效果。

| Abstract: | This paper proposes a new effective digital watermarking method that accepts JPEG lossy compression on the watermarked image to a pre-determined quality factor,and rejects malicious attacks.It embeds the watermark bits on the DC of the DCT transform coefficients,for most JPEG quality factor,the method is proved to be robust and effective. |
