摘要
隐秘通信系统的核心是信息隐藏技术 ,它着眼于被隐藏信息本身的不可探测性。近年提出的很多图像空域信息隐藏方法 ,绝大多数都在隐秘对象中遗留了嵌入信息的统计痕迹 ,为隐秘分析提供了便利。该文推导构建安全隐秘通信系统的条件 ,基于图像直方图保持的数据映射方法提出一种安全的隐秘通信系统方案 ,实验结果表明 ,该系统能够有效地阻止目前流行的统计检测分析。
The main technique for steganographic system is information hiding in which the existence of the hidden message should not be detectable. Many methods for information hiding into the spatial field of images are proposed in recent years. However, most of them make the stego-objects contain detectable statistic artifacts due to message embedding that can be used by the steganalyser. In this paper,the condition to construct a secure steganographic system is derived, and a secure scheme of steganographic system is presented based on histogram preserving data mapping. Experimental results show that the system can effectively prevent the current statistic steganalysis.
