An Security Enhanced Spatial Steganography Based on HVS.

Abstract: This paper presents a secure spatial steganography system against some powerful spatial steganalysis by employing HVS characteristics and chaotic technique. Firstly, this paper gives the embedding model, and then specifies the two key points of the embedding model: HVS JND model and generation of embedding location, which make the proposed method more imperceptible and more anti-extracting. By the security analysis to the embedding model, the security of proposed method is proved. Finally, experimental results show our method''s better performance than conventional spatial embedding scheme. [Copyright &y& Elsevier]
