Abstract

Abstract: LSB steganography is easy to implement hiding much information.So，it is a hot area of research in the information and network security.There are some analysis algorithms of LSB，such as SPA.A structured information hiding algorithm is proposed.It is able to analyze some properties of the adjacent pixels pairs in the image.Based on the properties，a structure of adjacent pixels is found.The structure doesn’t influence the statistic properties of the image.The experimental results show that the method can resist the attack of SPA and its performance is better than others in the efficiency and security of information hiding.

Key words: information hiding, structure of adjacent pixels, Structured Information Hiding Algorithm（SIHA）

摘要： LSB信息隐藏以其隐藏信息量大、隐藏方法简单等优点，成为信息安全领域研究的一个热点。针对LSB信息隐藏，出现了SPA方法等分析方法。通过分析SPA方法，提出了一种结构化的信息隐藏算法。该算法分析相邻像素结构体性质，找到一种相邻像素结构体。该结构体能够保持图像的统计性质。实验证明：该算法不仅能够有效地抵抗SPA统计分析方法，而且实现简单、计算量小，性能优于其他算法。
