Hiding the data in the Video is still an important research issue, but the problem with the traditional mechanisms it leads to the distortion and error prone. However, most of the video data hiding methods utilize uncompressed video data. Recent video data hiding techniques are focused on the characteristics generated by video compressing standards. Motion vector based schemes have been proposed for MPEG Algorithms. In this paper, the authors present a new data hiding scheme for H.264, MPEG encoded video sequences. Embedding takes place during the encoding process and utilizes the advanced inter prediction features of the encoder.
