图像信息隐藏的理论安全性研究

Study on theoretical security of information-hiding based on images

根据图像隐写分析的特点,对图像信息隐藏过程所引起的载体视觉特征和统计特征,特别是高阶统计特征的变化进行约束,改进并丰富了信息隐藏系统理论安全的经典模型——假设检验模型,并将其应用于具体图像信息隐藏的安全性分析中,实现了对图像信息隐藏系统安全强度的测评。

According to the characteristics of steganalysis, to restrict the visual and statistical, especially the high-level characteristic of the image carrier, the classical model called model based on the theory of hypothesis and proof-test was consequently improved and enriched. Then, the improved one was applied to the security analysis of specific hidden image information, thus testing of the security of information hiding system was accomplished.
