A Security Scheme Based on ARQ Technology for Image Hidden Communication
Yijun Ding · Microcomputer applications · 2009
Two questions must be solved in Image Hidden Communication based on data hiding,which hidden data can't be detected and is transmitted reliably on initiative attack.In this paper,information of image is expressed in terms of generalized information entropy,and constraint condition that the hidden data can't be detected is given.We solve the question that hidden data is transmitted reliably with ARQ technology in error control of communication.Detection of error and detection code for ARQ technology is proposed,and error detection ability of the code is proved.The scheme is suitable for Image Hidden Communication in public communication channel with high communication traffic,and make hidden communication reliable in the case of not all bits in m-bit hidden data are error.
