摘要 结合小波变换技术,提出一种新的脆弱水印算法。为了提高该算法的安全性,在生成水印信息和检测水印时映射到每个小波系数,并运用混沌理论,在提取水印时实现盲检测。实验结果表明,该方法在保证水印不可见的同时,能精确验证出图像数据中每个像素点的变化,具有良好的验证功能。 Combining with wavelet transform, a new fragile watermark algorithm is proposed. This new watermark algorithm adopts chaos theory for the purpose of security. The new algorithm realizes blind detection in the process of watermark extraction. The experimental results show that this algorithm can detect every change on pixel level, while the watermark remains invisibly.
