Recent study has found out that after multiple times of recompression, the
DCT coefficients of JPEG image can form an embedding domain that is robust to
recompression, which is called transport channel matching (TCM) method. Because
the cost function of the adaptive steganography does not consider the impact of
modification on the robustness, the modified DCT coefficients of the stego
image after TCM will change after recompression. To reduce the number of
changed coefficients after recompression, this paper proposes a …
