| 摘 要： | 文章提出了一种基于混沌序列的DCT域盲数字水印嵌入和检测新算法。该算法以二值图作为水印．通过混沌序列确定水印信号嵌入位置，根据JPEG标准的量化表系数确定水印的嵌入强度．只有利用正确密钥才能提取水印，保证了算法的安全性；提取水印时不需要宿主图像，实现了盲水印技术。实验仿真表明了该算法简单易行且对常见的水印攻击有较好的鲁棒性和实效性。

| Abstract: | In this paper, a new algorithm for blind digital watermarking based on chaotic sequences is presented..It decides the place where watermarking is embedded through the chaotic sequences, and the watermarking is only retrieved through the right secret key. The retrieval of watermarking need not original image, so it is a blind watermarking algorithm, The intention of embedding watermarking is based on the JPEG qualtization table, which help to embed more information. The experimental results show that this algorithm is easy to perform and is robust to most common signal processing attacks and can meet demand of the watermarking to a certain extent. |
