| Abstract;A method for scrambling MPEG video is proposed. Scrambling is done by exchanging the motion vector (MV) in the MPEG bitstream. Proposed method directly deal with the MPEG bitstream and exclusive MPEG encoders are unnecessary. The size of scrambled bitstream will not increase and image quality is maintained after descrambling. Since there are no MVs, intra frames are not modified and can be used for database and image search. Moreover, the MPEG bitstream structure is maintained and the scrambled bitstreams can be decoded by the standard MPEG video decoder. We demonstrate the effectiveness of this method by showing the simulation results of image quality and size of bitstream. (author abst.) |
