摘　　要：利用随机序列将水印信息嵌入到彩色载体图片绿色和蓝色分量的DCT系数中,提高了算法的安全性,同时在嵌入时将能量分散到4个相邻的DCT系数中,有效的提高了水印的不可见性和鲁棒性.In order to improve the security of the algorithm, watermarking information is embedded into the DCT coefficient of green and blue components of carrier image by using random sequence. At the same time,energy in embedding process is scattered into the four neighboring DCT coefficients to improve the invisibility and robustness of the algorithm.
