Natural Steganography in JPEG Compressed Images
2018
IS&T International Symposium on Electronic Imaging Science and Technology
In natural steganography, the secret message is hidden by adding to the cover image a noise signal that mimics the heteroscedastic noise introduced naturally during acquisition. The method requires the cover image to be available in its RAW form (the sensor capture). To bring this idea closer to a practical embedding method, in this paper we embed the message in quantized DCT coefficients of a JPEG file by adding independent realizations of the heteroscedastic noise to pixels to make the
