摘要：Reversible Watermarking methods are common now days in multimedia for copyright protection, which gives robustness by preserving no damage to cover image. But there are problems in reversibility, robustness and invisibility with the usual methods. To overcome these problems, this paper proposes an improved reversible watermarking using wavelet domain statistical quantity histogram enhancement and clustering (WDSQH-EC) method. Proposed method builds new embedding and extraction process and also security provision is done with a key generation. The results are satisfactory in terms of invisibility, robustness and reversibility. In embedding the watermark the enhancement on pixel-wise is done to increase practical applicability and also trade-off between robustness and invisibility. This method shows effectiveness when enhancement has been done. It has to provide more strong when more compressions and unintentional attacks had taken.
