Intra-frame distortion drift is a big problem of data hiding in H. 264/AVC video streams.
Based on a thorough investigation of this problem, a novel readable data-hiding algorithm,
which can embed data into the quantized discrete cosine transform (DCT) coefficients of I
frames without bringing any intra-frame distortion drift into the H. 264/advanced video coding
(AVC) video host, is presented in this paper. We exploit several paired-coefficients of a 4 \,*\,
4 DCT block to accumulate the embedding induced distortion. The directions of intra-frame …

A robust data hiding algorithm for H. 264/AVC video streams without intra-frame distortion drift

This paper presents an improved H. 264/AVC data hiding method based on without
Distortion Drift technique and BCH syndrome coding technique. The without Distortion Drift
technique in this paper is that we exploit several paired-coefficients of a 4 4 DCT block to
accumulate the embedding induced distortion and use the directions of intra-frame
prediction to avert the distortion drift. The BCH syndrome coding technique is that we
encode the embedded data by BCH coding before hiding data. The experimental results …
