Abstract :
this paper, a new improved adaptive invertible information hiding method for MPEG video is proposed. Hidden data can be extracted without original signal and the original MPEG video data can be recovered if needed. Data embedding is controlled by a special pseudo-random key mechanism. The proposed algorithm can be implemented with low complexity and low visual distortion for covert communication applications. Experimental results show that the algorithm can survive appropriate MPEG recompression and has low visibility.
