摘要(Abstract)：

为提高图像水印的安全性,在空域中模仿转盘密码锁的工作方式进行密钥计算.在嵌入水印前,利用旋转变换矩阵和向量平移公式模拟转盘密码锁的上锁;在检测水印前,模拟转盘密码锁的解锁,上锁和解锁的计算结果决定水印嵌入与检测的位置.在DCT域中采用差分方法对水印进行嵌入与检测.利用一种自适应算法进行水印强度调节,在图像的不同分块区域嵌入不同的水印强度.在水印检测时,利用一种具有优先级的膨胀算法辅助水印的复原.检测结果表明:该方法能够较好地抵抗4位以上的量化攻击、83级以上的JPEG压缩攻击、均值在82以下的高斯噪声攻击和46.07%以下的几何裁剪攻击,安全性好、抗攻击性强.

关键词(KeyWords)：图像水印;高安全性;自适应;抗攻击性;DCT变换
