摘要

提出了一种新的基于多策略的数字图像盲水印算法。水印嵌入到原始图像的多分辨率小波变换域中。该算法在扩频技术的基础上加入了新的技术，提高了鲁棒性、隐蔽性和安全性。该方法是将不同分辨率的多幅水印交叉嵌入到小波变换域中。结果表明，恢复的水印在各种攻击后都表现出较好的性能。

A new DWT & multi-strategy watermark embedding algorithm

A novel blind digital image watermarking algorithm based on multi strategy is put forward in this paper. The watermark is embedded in multi-resolution wavelet transform domain of the original image. Based on spread spectrum techniques, the algorithm is composed of new technique to improve robustness, imperceptibility and security. In this technique, we interlace several copies of watermark in different resolution to embed in wavelet transform domain. As a result the recovered watermark is shown better performance after various attacks.
