Space reservation technique at distributed level for hiding reversible data in the encrypted images

Reversible information hiding (RDH) in protected images is now receiving greater attention from the study team. Since it safeguards the privacy of supplemental information while still being a covered media, it is attractive for application in analytics, online clouds, diagnostic devices, and other disciplines. This study proposes an original method for irreversible data hiding in secret picture (RDH-EI). After securing your cover image, our method uses the tactic of assigning adequate space for the additional data. We begin by identifying suitable blocks for data occlusion in various parts of the image. Before the photo is encoded, some of the S-box of these chunks are supported into other areas of the image to employ a high-performance traditional RDH approach. Once the image has been encrypted, these LSB-planes are used to hide further data. Restoration of the original cover image and error-free supplementary information extraction are often guaranteed. The proposed strategy is quite straightforward and simple to comprehend. Experiments' results show that our method is superior to traditional ones for embedding concealment in protected images.
