基于分形艺术图形的密写术

Steganography based on fractal art images

密写术作为信息隐藏的一个重要分支,是近年来研究的热点领域之一。目前高校和研究机构已经提出了许多基于图像、视频、音频和文本载体的密写算法,然而这些载体具有各自内在的统计特性,这些统计特性的变化给攻击者提供了很好的检测依据。分形艺术图形生成简单,并且具有可以控制产生特性各异的统计特征的特点。因此提出以分形艺术图形作为载体进行信息隐藏的密写新算法。理论和实验结果表明,以分形艺术图形作为隐藏载体,具有传统载体无法比拟的优点。该研究结果对拓宽密写算法的研究具有现实意义。

As an important subdiscipline of information hiding, steganography is one of important research fields in recent years. Now universities and research communities have put forward a lot of steganography algorithms based on images, videos, audios and texts. But these carriers have inherent statistical characteristics, the change of which may provide good basis for attackers. The creation of fractal art images is simple, and the created images have different statistical characteristics which can be controlled. A new steganography algorithm is presented based on fractal art images. The theory and result of experiments indicate that fractal art images as hidden carriers exceed the traditional carders, The result has practical significance to extend the research of steganography.
