利用图像进行信息压缩和隐藏

The Method of Hiding Compressed Information in Image

简要介绍了信息加密技术和信息隐藏技术思想,提出了一隐一密、先压缩后隐藏的进一步优化信息隐藏技术的方法,并设计了一种简单易行的信息嵌入算法,完整地介绍了信息隐藏与恢复的过程,实现了一个利用图像进行信息压缩和隐藏的系统,取得了良好的效果。

Firstly,information encryption and hiding techniques are briefly presented and a new method that optimizes information encryption technique is put forward.In the method,the secret information is hided with unique encryption key and first compressed then hided.Furthermore,a kind of easy information embedding algorithm is designed and infor-mation hiding and resuming processes are completely introduced.Finally,this paper completes a system of hiding com-pressed information in image.The system proves that the method of hiding compressed information in image is effective and practical.
