Abstract: Encoding method for steganographic codes based on GF(3) is presented. A ternary steganographic code is obtained through ternary steganographic Golay codeswhich is better than binary codes. This paper proposes a fast algorithm based on ternary Golay steganographic codes. This algorithm can reduce computational complexity of encoding, improves the efficiency of the steganographic algorithm.
