基于调色板图像的隐写算法研究

Research on Algorithm of Steganography Based on Palette Image

摘要: 一般调色板图像的颜色种类比较少,用此类静态图像制作隐秘图像安全性较差。为了提高信息隐藏的安全性,提出一种新颖而又简洁的调色板图像的颜色对构造算法。实验证明:用这种算法构造的以颜色对为基础进行嵌入的隐秘图像,在抗攻击能力上显著强于同类的嵌入算法。

Abstract: There are fewer colors in palette images than in true color images.Stego images may have poor security if they come from embedding message into palette images. Hence,a novel color pairs constructing algorithm is proposed to improve the security of information mioling.The simulation results verify the effective of the present algorithm in the security.
