基于软判决相关攻击的信息隐藏方法研究

Research on Information Hiding Techniques Based on Soft-Decision Correlation Attacks

提出一种基于软判决相关攻击重建同步的信息隐藏方法,根据图像自身的内容,采用特征点提取和Delaunay三角剖分算法得到同步信息,该信息与秘密信息经过卷积码编码,嵌入到图像不同分量中频系数上。实验表明,该方法对仿射变换、长宽比改变、高斯噪声,图像压缩等攻击都具有强鲁棒性。

Proposes the simultaneous reconstruction information hiding techniques based on soft-decision correlation attacks. According to the image of their own content, uses the feature points extrac- tion and Delaunay triangulation algorithm to get the synchronization information, the information and confidential information can be embedded in the different frequency coefficients of different components of the images through the convolution coding. Experiment shows that the method has strong robustness on affine transformation, changing the aspect ratio, Gaussian noise, image compression and other attacks.
