JPEG steganography schemes take the effects of embedding in the spatial domain tend to exhibit higher security and introduce less artifacts that can be captured by the prevalent steganalyzers ensuing the paradigm, this work proposes a new plan of the distortion measure for JPEG steganography by incorporating the statistics of both the spatial and DCT domains. The spatial statistics of the decompressed JPEG images are firstly well characterized with distortion measures of some efficient steganography schemes in the spatial domain and the resulting embedding entropies of spatial blocks in arrangement with DCT blocks be then transformed into the DCT domain to obtain the distortion measures for JPEG steganography. Investigational cost demonstrate that the normal system outflanks impressively other best in class JPEG steganography schemes and UERD, for the most effective feature set GFR at present, and rivals them used for other characteristic sets.
