摘要：
In this paper, we propose scrambling and descrambling techniques for privacy protection of moving objects in video surveillance system. The methodswere embedded on H.264 encoder and decoder during macroblock based motion estimation of the P and B frames. An adaptive Peano-like scan technique with pyramid structure is introduced in order to dealwith scrambling information for both of frequency and spatial domains. Our algorithm is implemented in ffmpeg h264 decoder and x264 encoder.
