Reversible Data Hiding Based On H.264/AVC Intra Prediction

This paper proposes a novel high capacity reversible image data hiding scheme using a prediction technique which is effective for error resilience in H.264/AVC. In the proposed method, which is based on H.264/AVC intra prediction, firstly the prediction error blocks are computed and then the error values are slightly modified through shifting the prediction errors. The modified errors are used for embedding the secret data. The experimental results show that the proposed method, called shifted intra prediction error (SIPE), is able of hiding more secret data while the PSNR of the marked image is about 48 dB.
