Recently, many data embedding schemes using the quantized DCT coefficients have been proposed for achieving the robustness. However, most of the schemes lack to strike a trade off between the embedding capacity and the visual quality. Achieving more embedding capacity by maintaining the visual quality has become a challenging task. Most of the DCT based data embedding schemes result in various visual distortions for not considering the HVS characteristics while embedding. The widely used visual quality measure PSNR is not sufficient to assess the quality of the distorted image/video content. However, the HVS based visual quality metrics PSNR-HVS and PSNR-HVS-M are very much suitable when the data is embedded in the DCT domain. We propose a reversible data embedding scheme which embed the data during the process of MPEG-4 compression of video. Experimental results show that the proposed scheme achieves higher embedding capacity and better visual quality in terms of HVS based metrics.
