Steganography based on Minimizing Embedding Impact function and HVS

In order to improve the security of Steganography System, according to the principle of Minimizing Embedding Impact, make use of Syndrome-Trellis Codes which is near-optimal embedding and Human Visual System, this paper proposed a distortion function used for Minimizing Impact for Embedding in discrete wavelet transform domain. The approach analysed the influences of luminance, frequency and texture masking factor to the cover distortion impact, and make sure that the embedding impact to the cover minimizing and centralize in un-sensitivity domain. Experiment result show that the proposed approach maintains a good visual quality of stego image and can improve the embedding efficiency and security evidently with the use of Minimizing Embedding Impact in wavelet domain.
