Dynamic selective information hiding based on search order coding withn low bit rate

摘要

A low bit rate information hiding scheme is important for efficient communication. According to our observation, in a search order coding based (SOC based) hiding method, the case distribution generated from different images and from different secret strings is different. Based on this characteristic, we designed a dynamic selective, SOCbased, information hiding scheme to achieve a desirable compression effect. That is, depending on different case distributions, we used different coding modes to
