摘　　要：DCT域的图像数字水印算法具有不可察觉性,有较好的鲁棒性,实现了二值图像嵌入的过程。通过实验表明,该算法能够进行D/A、A/D转换及量化等信号处理和有损JPEG压缩、滤波,也能进行一般的几何变换,安全性较高。Digital watermarking algorithm based on DCT domain is not easily detected and has high robustness.Inaddition,it realizes the embedded process by using binary image.This algorithm experiment results show that this algorithm has high safety when it does signal processing,for example D/A convert、A/D convert and quantization,and does the JPEG lossy compressing、filtering and ordinary geometric translation.
