基于图像的信息隐藏安全性分析

信息隐藏是一种新兴的信息安全技术,在信息战、数字媒体的知识产权保护和票据防伪等方面有许多重要的应用。但作为一门信息安全领域的学科,对它的安全性一直没有系统的理论研究。我们结合信息隐藏算法的相关知识,对基于图像的空域LSB隐藏算法和DCT变换域算法的安全性进行了分析,希望能对安全性的理论研究有所帮助。

The security analysis based on images information hiding

Information hiding is an rising information security technology,which has been more and more important in the fields ,such as information war, the protection of information property right of digital media and anti-fabricated ticket. But as a new subject in the field of information security,there has not been systematic theory research on it's security.Based on related knowledge of information hiding algorithmic,we analyse the security of LSB hiding algorithmic based on image and DCT domain commutation algorithmic.we hope to give a help for security theory research.
