Abstract

Existing robust reversible watermarking methods usually have poor visual quality or unstable robustness and reversibility, implies that reversibility cannot be assured even in lossless channel. In this paper, a novel robust reversible watermarking method is proposed. In the proposed method, bit plane manipulation is applied to hide watermark bits in bit planes that are lesser affected by attacks. Region filtering is also adopted to find blocks that result in low variance for watermark embedding to further increase its robustness. Experimental results show that our method has improved performances compared with state-of-the-art technology, better surviving bit rate, a robustness measure, is obtained in the proposed algorithm.
