Steganographic coding technique is an advanced research hotspot in the field of multimeida steganog-raphy which can effectively improve the security and robustness of steganography. Recent advances in stegano-graphic coding based on linear codes are reviewed in this paper. Regarding the challenges posed by the rapid de-velopment of steganalysis ,the key steganographic coding methodology——— matrix embedding is concluded as three developmental stages:aiming at reducing the modification,aiming at selecting the modification area,and aiming at minimizing the distortion. Then,with the unceasing expansion of application environment for steganog-raphy,it is indicated that matrix embedding in multicast communications and that in conjunction with linear cod-ing for enhancing the robustness are the new trends of steganographic coding technique.
