Abstract

The reversible data embedding is emerging due to its various watermarking and steganography applications. The requirement of reversibility may lead to more modifications to the cover content which result in the trade off between the visual quality and embedding capacity. In this paper we propose a reversible data embedding scheme for MPEG-4 video, striking the trade off, which embeds the data into non-zero AC coefficients of quantized DCT blocks. The experimental results show that the proposed scheme improves both the visual quality and embedding capacity.
