This paper presents implementation of Digital Water marking for video sequences using 3D-DCT Approach. In this method Water Mark (WM) is embedded in the DCT domain of uncompressed video sequences by modifying the 3D-DCT Coefficients in each 8 x 8 blocks of individual frames. Mid-range frequency coefficients are selected to insert the WM. In this, WM is spread in both frequency and spatial domain of video stream since each block contains both temporal and spatial information of video. Secret key… CONTINUE READING
