Abstract: This paper proposes a robust steganography method in H.264/AVC with secret sharing.The embedded secret data is first distributed as a specific polynomial,then we obtain a series of sub-secret and embed the sub-secret into each frame of the video with prediction mode and paired-coefficients.We can restore the complete hidden data by using the t sub-secrets of the video frames.The experiment results show that the method has the high frame loss and frame error robustness,when the random frame rate is less than or equal to 20%,the method can recover secret data completely.In addition,the method can avoid intra-frame distortion drift and has better visual concealment.
