摘　　要：将古籍数字化技术以及DCT和DWT域水印算法这三大良好的特性相互结合,提出一种基于DCT和DWT域水印算法的古籍数字化图像版权保护方法.为保护古籍数字化图像版权,对古籍数字化图像序列号顺序进行快速打乱,对打乱顺序的古籍数字化图像利用DWT域水印算法得到古籍数字化图像.实验结果表明:作为一种拥有安全性能高以及快速高效特性的版权保护方法,在低迭代次数的情况下,该算法能够取得良好的版权保护效果.In this paper,combined with the three characteristics of ancient book digitalization technology and DCT and DWT domain watermarking algorithm,and a protection technology of digital image copyright of ancient books based on DCT and DWT domain watermarking algorithm is proposed. In order to protect the copyright of the digital image of ancient books,the sequence of digital image sequence of ancient books is quickly disrupted,and the digital image of ancient books is obtained by using the DWT domain watermarking algorithm for digital images of ancient books in disorder order. The experimental results show that as a copyright protection method with high safety performance and fast and efficient characteristics,the algorithm can achieve good copyright protection effect at low iterations.
