In this paper, a channel selection rule for YASS （Yet-Another-Secure-Steganography） is proposed. Secret message embedding imposes distortion to the cover image. The larger the distortion, the less secure the stegano...

For steganalysis of JPEG images, features derived in the embedding domain appear to achieve a preferable performance. However, with the existing JPEG steganography, the minor changes due to the hidden secret data are ...
