摘要
图像自适应隐写和隐写分析技术是近年来信息隐藏领域的研究热点和难点。自适应隐写通过自适应选择嵌入更改位置并结合高效编码方法提高了隐写安全性,而相应隐写分析技术主要通过捕捉图像统计特性改变来发现隐写行为。首先对图像自适应隐写的基本原理进行了介绍,然后梳理总结了图像自适应隐写和隐写分析技术的研究进展并指出了现有研究存在的问题,最后对图像自适应隐写和隐写分析技术研究进行了展望。
Adaptive image steganography and the corresponding steganalysis techniques are the popular research topics in information hiding. Adaptive steganography improves the security by selecting the embedding change positions adaptively and efficient coding methods while the steganalysis tries to detect the steganography embedding by capturing the changes of image statis- tics. First, the principle of adaptive image steganography is introduced. Then, the research sta- tus on adaptive image steganography and steganalysis techniques is summarized and the key is- sues are pointed out. Last, the trend in development of adaptive image steganography and stega- nalysis techniques is discussed.
