| 摘 要： | 摘要信息隐藏的核心是隐写容量和隐秘信息的安全性。采用批量二值图像和图像分块技术，提出了一种符合Cachin安全性定义的批量二值图像隐写模型。在满足静态Markov链和独立嵌入的条件下，分析了批量二值图像隐写的容量，并证明了基于K-L散度的批量二值图像隐写的安全性。批量二值图像隐写的容量与载体数、图像分块等相关性实验的验证和分析表明，本模型具有一定的理论和应用价值。

| Abstract: | The core of steganographic research is capacity and security of hiding information. According to Cachin'definition of security and properties of binary image block of host image, batch steganographic model of binary images was presented. Batch steganographic capacity of binary images was summarized, when satisfying static markov chain and mutually independent of embedding in covers. Security of the model was proved under certainly condition. The experimental results and analysis show that the model satisfies steganographic requirement for security. The research results are helpful for theory and application. |
