摘要

基于图像处理、提升整数小波和信息隐藏理论

提出了具有双阀值的信息隐藏算法

阐述了实现信息隐藏的原理

并给出了具体算法及实现过程.该算法把秘密数据通过双阀值技术嵌入到图像整数小波变换后的高频子带的系数中.嵌入数据时

解决了小波反变换时的灰度值溢出问题

增加了相同载体下的信息隐藏的容量

而且提高了秘密信息的安全性.通过实验数据分析了该算法的阀值变化、嵌入容量和安全性等问题

结果表明:该方法提高了秘密信息的安全性和隐藏容量.

Abstract

Based on theories of lifting integer wavelet

image processing and information hiding

the authors propose an information hiding algorithm with two thresholds

introduce its principle and steps to achieve

and give the specific algorithm and implementation process.It embedded secret information in integer wavelet high frequency subband coefficient using two thresholds.When extracting the embedded data the gray value overflow problem is resolved during wavelet inverse transform

and increased size and security of secret information.It was analyzed the threshold value variation

size of secret data and security with experiment data etc.Experiments show the method can embed secret information in great size.The results show that this method increases the safety and hiding capacity of secret information.
