In this paper, a content-based encryption scheme for wireless H.264 video in the compressed domain is proposed. First, the information of prediction mode, motion vector and prediction residual energy is extracted from H.264 bitstream and then jointly utilized to compute measures to classify the complexity of the video content in terms of texture and motion. Then according to the classification results, videos with different content features are encrypted with selective encryption in different… CONTINUE READING
