In this paper, we propose an algorithm for hiding (DNA Deoxyribonucleic acid) sequence in H.264/AVC video. The DNA sequence is first encrypted by a rule before hiding, and then we embed encrypted DNA sequence into the quantized discrete cosine transform (QDCT) coefficients of the 4x4 macroblocks (MBs) of Intra-frames (I-frames). To avert the distortion drift, we use the directions of I-frame prediction. By using all paired-coefficients that meet -1, 0 and 1, we do not need use any threshold for limiting the capacity of embedded data. The experimental results show that the proposed algorithm has improved with other existing algorithms in term embedding capacity.
