Abstract:
1. A system for protecting video content comprising: computer memory comprising a stored set of instructions for processing video data; and at least one microprocessor configured to process the video data according to the stored set of instructions, the stored set of instructions configured to: receive encoded video data from a video source, said video data comprising at least one video frame; apply at least one wavelet transform to a selected frame of the at least one video frame k iterations to generate image data Pk and associated support spaces, where k is an integer greater than 1, wherein each of said iterations re-represents a preview of the previous iteration as a quarter-size preview, together with three quarter-size support spaces; separate said image data Pk into dataset A and modified image Pk′; wherein reproduction of the selected frame of the at least one video frame requires said dataset A and said modified image data Pk′; re-encode and compress said dataset A of said image data Pk; apply data-hiding operation to said re-encoded and compressed dataset A to generate a modified dataset A′ such that dataset A requires a key for reconstruction from dataset A′; re-encode and compress said modified image Pk′; and output at least one video stream comprising a frame header, said modified dataset A′ and said re-encoded and compressed modified image Pk′.
