A steganographic method based on tetris games
This paper proposed an undetectable steganographic method through Tetris games. The stegoed tetrimino sequence will be different in each game play, regardless of a secret message being changed or not. The proposed extraction process can automatically extract the secret message while the receiver plays Tetris. A simulator is given to demonstrate that the proposed method can work well on Tetris. A theoretic proof and some experimental results are given to show that the proposed method is undetectable.
