中文摘要：

针对贺兰山岩画文物数字图像的保护和安全问题,为防止这些文物数据在网上共享时被非法拷贝或用于其他途径,在文物图像中批量嵌入相同水印.文中提出采用FDCT滤波矩阵实现离散余弦变换,将水印的低频和中频信号嵌入到原始图像的中频系数中.实验结果表明：该算法速度快并具有较好的鲁棒性.

英文摘要：

This paper focus on the digital watermark technology and try to protect the copyright and securities of Mount Helan rock painting. In order to prevent the 2D relic data shared in Internet from being illegally copied or used with some other purpose, this algorithm batch embed the same color images as watermark information into the relic images. The algorithm finished discrete cosine transform by using FDCT and embedded low frequency and intermediate frequencyt of watermark into intermediate frequency of relic image. The result indicates that the algorithm is rapid and robustness.
