Reversible data hiding in encrypted images with secret sharing and hybrid coding

Reversible data hiding in encrypted images (RDHEI) is an essential security technique. Most RDHEI methods cannot perform well embedding capacity and security. To address this issue, we propose a new method using Chinese remainder theorem-based secret sharing (CRTSS) hybrid coding. Specifically, coding first proposed for RDH to achieve high capacity. At the content owner side, novel iterative encryption designed conduct block based perfectly preserving spatial correlation of original blocks their blocks. Then, CRTSS with constraints exploited generate multiple image shares, which correlations are also preserved. Meanwhile, provides good properties method. Since there strong each share, data-hider can exploit improving On receiver even if some shares corrupted/missing, be losslessly recovered as long enough uncorrupted marked obtained. Experiment results show that outperforms state-of-the-art methods, including (SS) terms
