大容量的信息隐藏算法

High Capacity Information Hiding Algorithm

提出一种基于空间域的自适应多平面位的信息隐藏算法,该算法计算复杂度低、信息隐藏量大。实验表明在不影响图像视觉效果的前提下,其信息隐藏量比LSB算法大,并具有更高的安全性。该算法的主要思想是对每个像素点进行判断,根据HVS的特性,在最高非0有效位后的指定位(y)开始嵌入隐藏信息,嵌入到另一个指定位(z)为止。

A hiding information algorithm of adaptive multiple plane-bit based on space domain is proposed,which has low computing complexity and large information capacity hidden.Experimental results show hiding information capacity of this algorithm is much larger than LSB algorithm,and security is much higher than LSB algorithm.It＇s main idea is to judge every pixel point so that hiding information will be embedded from specified bit（y）behind the highest non-zero effective bit until another specified bit（z）according to HVS＇s property.
