独立分量分析(ICA)是一种基于高阶统计量的信号分析方法,它可以找到隐含在数据中的独立分量,已广泛应用于信号处理领域。信息隐藏是一种新兴的技术,其目的在于将秘密信息隐藏于另一非机密信息中。本文提出一种新的信息隐藏技术,即将ArnOld置乱后的秘密图像嵌入到载体图像中,再利用ICA算法从中提取出秘密图像。仿真结果表明该算法有效可行。Independent Component Analysis(ICA)was widely used in signal processing,which is a signal analysis method based on signal's high order cumulants,it can find out the latent independent components in data.Information hiding technology is a new method in information processing;the hiding information is embed in public information.This paper introduces an algorithm based on ICA for information technology.This paper embeds the cryptogrammic hiding image in public image,then using ICA algorithm to abstract the hiding image.The results of emulation indicate this algorithm is available and feasible
