This paper proposes a novel video steganography during motion estimation (ME). Compared with existing schemes using motion vector (MV) as the information carrier, the new approach has been enhanced from two aspects to improve steganographic security. First, to reduce the single change distortion, a technique called multi-path ME is introduced to generate optimized alternates for MV replacement. Secondly, to improve both the embedding and computational efficiencies, a flexible embedding structure is designed to perform matrix embedding.
