Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, we propose a high capacity MSB prediction-based method with sufficient reversibility for data hiding in encrypted images. First, as preprocessing of data hiding, the proposed method introduces markers and flags to the payload and encrypted image, respectively. Additionally, by defining precise conditions for MSB prediction, our method can guarantee the perfect reversibility. Experimental results show the effectiveness of the proposed method in terms of reversibility and hiding capacity.
