A Reversible Data Hiding Method in Compressible Encrypted Domain for OpenEXR Images
Noa Kikuchi, Shoko Imaizumi (Chiba Univ.) EMM2023-84
Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, we propose a method to achieve high-capacity reversible data hiding (RDH) for OpenEXR images with compressible encryption. In the proposed method, an Encryption-then-Compression (EtC) system is introduced for encryption so that the dynamic range of the original image is preserved. In the encrypted domain, an RDH process based on prediction error expansion is applied. The proposed method is characterized by its ability to decrypt without data extraction on the decryption side. In the simulation, we evaluate the hiding capacity, the
compression efficiency by JPEG XT, and the image quality of the marked images to confirm the effectiveness of the proposed method.
