信息隐藏是信息安全领域的重要研究内容之一。介绍了基于纠错码的信息隐藏的一般原理,阐述了主要实现方法。针对一种基于纠错码编码冗余的信息隐藏算法框架,给出了以JPEG图像为载体的实现方法,并分析了其特点。最后指出了值得进一步研究的问题。
Information hiding is one of the most important research subjects in the field of information security.This paper summarized several information hiding methods using error-correcting code,then proposed an algorithm based on the encoding redundancy of error-correcting code,and gave the realization in JPEG encoded images and the characteristics are analyzed.
