Abstract This paper proposes a new constructive texture synthesis steganographic scheme
by compressing original secret messages. First, we divide the original message into multiple
bit blocks, which are transferred to decimal values and compressed into small decimal values
by recording their interval sign characters. Then, a candidate pattern is generated by
combining the given source pattern and boundary extension algorithm. Furthermore, we
segment the candidate pattern into multiple candidate patches and use affine transformation
algorithm to locate secret positions on a blank canvas, which are used to hide the sign
characters by mapping the candidate patches. Finally, we select the candidate… More >
