摘要

Data hiding is a technique which embeds secret data into cover media. It is important to multimedia security and has been widely studied. Recently, some researchers paid attention to reversible data hiding methods. The proposed schemes are able to reconstruct the original image from the embedded index when embedded data are extracted. In this paper, we propose a new reversible method in vector quantization (VQ) compressed images. Our scheme takes advantages of the relationship of neighboring blocks to achieve reversibility. Compared to past studies, for example, Wang et al.'s method, the experimental results show that the proposed method outperforms the past one in terms of higher compression rate and larger c [apacity.
