Recently, several encryption algorithms have been proposed, which are applied to MPEG-2 video streams. These algorithms try to optimize the encryption process and improve encryption speed by exploiting the spatial and temporal properties of video retrieval and display process. As a new branch of encryption, transparent scrambling has its own merits and… CONTINUE READING
