| 摘 要： | 通过对SPA方法和SIHA算法的分析,提出了一种扩展结构化的LSB信息隐藏算法（an extened struc-tured steganography based on adjacency pixel,ESSA）。通过分析图像相邻像素结构体,找到相似的相邻像素结构体,根据这些相邻像素结构体的统计性质变化来隐藏信息。实验证明：该算法不仅能够有效的抵抗SPA统计分析方法,而且实现简单、计算量小,隐藏优于其他算法。

| Abstract: | An extened structured steganography based on adjacency pixel（ESSA） was proposed by analyzing the SPA algorithm and SIHA algorithm.ESSA can be used to analyze some properties of the image fixel pairs.Based on the properties,a monotonous sequence of restoration was found.The sequence can keep the statistic properties of the pair unchanged.The experiment results show that the method can resist the attack of SPA and its performance is better than that of others in the efficiency and hiding capacity of information hiding. |
