小波分解在信息隐藏中的应用研究

Research on the application in information hiding with wavelet transform

从数字水印的频域研究法出发,提出了一种基于小波多分辨率分解的信息隐藏方法和步骤,并对其隐藏效果进行了分析.结果表明,这种方法不仅能很好地对信息进行隐藏,而且当隐藏信息的载体受到攻击时,仍能有效地提取出隐藏信息.

This paper proposes a method of hiding information based on multiresolution wavelet transform as viewed from the research method of digital watermarking frequency field, which can hide the information very well. The analysis of the hiding effects shows that this method also can protect the information against severe attacks.
