Abstract

Abstract: The evaluation of the steganography performance draws wide attention from the public in the research of the information hiding.This paper proposes a feature-based method to evaluate the JPEG image steganography techniques by contrasting the features abstracted from the images before and after embedding secret messages.In the multi-feature processing，it uses the Principal Component Analysis（PCA） to get the evaluation value.

Key words: information hiding evaluation, image features, Principal Component Analysis（PCA）

摘要： 在基于图像的信息隐藏研究过程中，人们对信息隐藏性能的评价十分关注。提出了一种基于特征的JPEG图像信息隐藏隐蔽性的评价方法。此方法首先提取信息隐藏前后的JPEG图像的特征，对这些特征处理后进行作差得到特征改变量，然后将得到的多维特征改变量进行主成分分析法综合评价，从而实现对隐藏方法隐蔽性的评价。
