An information hiding system based on reference matrix

Inspired from predecessors' work, in this paper, a data hiding system with good hiding quality is proposed. For one cover pixel pair, three binary secret bits can be embedded. Compared with the published work, we can explore embedding space fully and have achieved better hiding quality with acceptable embedding capacity. Moreover, there are multiple safeguards to ensure the security of the transmitted secret information and the calculation in this paper is simpler than the published ones.
