Abstract H.264/AVC video is one of the most popular multimedia and has been widely
used as the carriers of video steganography. In this paper, a novel motion vector (MV)
based steganographic algorithm is proposed for the H.264/AVC compressed video
without distortion. Four modules are introduced to eliminate the distortion caused by the
modifications of motion vectors and guarantee the security of the algorithm. In the
embedding block, the motion vector space encoding is used to embed a (2n+1)-ary
notational number into an n-dimension vector composed of motion vectors generated
from the selection block. Scrambling is adopted to disturb the order of… More >
