基于数位信息的信息隐藏方法
A Method of Information Hiding Based on the Digital-Position Information
-
摘要: 描述了一种基于数字位置信息的信息隐藏方法,给出了一个单位增广矩阵,并在此基础上给出了具体算法.该方法若用单个数位信息,在n=2m-1时,嵌入效率可达到m,有较高的数据嵌入效率;若用多个数位组合信息,可在保持嵌入效率不变的条件下,数据嵌入率近似等于1(n较大时),在相同比特数的宿主信息中,可嵌入较多的隐藏信息,可用于流媒体等信息量较大信息的隐藏.文中所述的方法,计算复杂度不高,易于硬件实现,已用微型计算机在局域网上进行了模拟实验,获得了较好的实验结果.Abstract: This paper presents a method of information hiding based on the digital-position information, bringing forward an augmented identity matrix and a definite arithmetic upon it. In this method, if the single digital-position information is used, embedding efficiency can achieve m when n = 2m -1. And if the multi-digital-position information is used, data embedding rate can almost reach 1 when n is big enough, with the condition of an unchanged embedding efficiency. So more information can be hided in the host information with same bits and it can be used in stream multimedia, hidings with great information, etc. The proposed method with low computing complexity can be realized easily. Satisfying experimental results are gained on PC and LAN
