摘要
随着网络安全和数字技术的快速发展 ,信息隐藏越来越受到各个领域的重视。信息隐藏与信息加密不同 ,它着眼于隐藏信息本身的存在 ,通常被解释为把信息隐藏于其它信息当中。文中介绍了信息隐藏的有关概念 ,建立了基于熵的信息隐藏理论模型 ,提出了实现信息隐藏的一些新算法 。
Information hiding, as an emerging technology, is different from information encryption technology. We propose using the concept of entropy to construct a theoretical model of information hiding; Section 2 explains our proposal in some detail. Section 3 explains our information hiding algorithm. This algorithm consists of two parts: hiding (subsection 3.1) and de hiding (subsection 3.2). Fig 2 shows how video information about a missile can be successfully hidden by our information hiding algorithm based on entropy.
