拉格朗日插值方法在数值信息隐藏与分析中的应用

Using Lagrange Interpolation Method in Information Hiding Analysis and Application

目前的信息传送绝大部分是基于互联网开展的,而由TCP/IP理论构建的互联网从机理上就无法保证传送的信息安全。为此,本文尝试采用数值逼近的经典理论-拉格朗日插值方法,展开数值信息隐藏与分析地研究。通过对传送数据加入前向干扰项、后向干扰项以及隐藏区间的方法,实现真实数值信息隐藏在海量的传送数据之中。不采用本文专有的信息分析方法,通过海量传送数据是无法还原出真实数值信息的。

The current information transmission are mostly based on Internet, and the TCP / IP theory to build the Internet from mechanism cannot guarantee the transmission of information security. Therefore, this paper attempts to use the numerical approximation of the classical theory of Lagrange interpolation method, information hiding and analysis research. Based on the transmission of data prior to joining to distractors, posterior to the distractors, and hide the interval method, realizes the true data hidden in the transmission of data. Not using our proprietary information analysis method, through the transmission of data is not a real data.
