Reversible data hiding (RDH) in compression domain is an important research issue in the security of digital multimedia. Obtaining a high embedding rate and a low compression rate are the main goals of compression domain RDH. This paper proposes a novel RDH scheme to improve joint neighboring coding (JNC) scheme. In embedding process, the first index SC 1st(More)
In this paper, a novel reversible data hiding scheme which utilizes SMVQ prediction indices to embed secret data is proposed. As a result, it improves Yang’s work, which takes advantage of counts of indices in data embedding. Our approach enhances the prediction of SMVQ, resulting in a more concentrated distribution of indices. Based on the distribution of(More)
