The high embedding steganographic method based on general multi-EMD

The hidden secret message capacity, stego-image quality and security are three important conditions for data hiding technology. According to these requirements, an effective security protection with high hiding capacity steganographic method based on general multi-EMD is proposed in this paper. The major contribution of this method is not to need more complicated embedded steps when the secret data is embedded and additional information when the secret data is recovered, respectively. From our simulation results, the proposed scheme not only maintains the original data hiding requirements but also achieves higher capacity than Kuo-Wang scheme.
