Practical polar coding method to minimize the embedding impact in steganography

This paper proposes a new practical polar coding methodology for constructing steganographic scheme. We use syndrome coding with binary embedding operation. The approach exploits the form of the syndrome, calculated from cover and secret message. A connection between the syndrome decimal value and the embedding changes position is established and enables defining a new steganographic algorithm. The wet paper codes can also be implemented using this method. Experimental results prove that the scheme minimize the embedding impact with a reduced time complexity compared to the first Polar Coding Steganography (PCS).
