Since current versions of Reversible Data Hidden in Encrypted Images (RDH-EI) rely on a single data-hider, recovering the original image will not be possible in the event that the data-hider is compromised.

摘要

Since current versions of Reversible Data Hidden in Encrypted Images (RDH-EI) rely on a single data-hider, recovering the original image will not be possible in the event that the data-hider is compromised. In order to address this problem, this study suggests a unique RDH-EI paradigm that is based on covert sharing and includes multiple data-hiders. The original image is divided into several encrypted copies of identical size and distributed to several data-hiders in order to conceal data. To obtain the corresponding tagged encrypted image, every data-hider can separately embed information into the encrypted image. If sufficient annotated encrypted images are gathered from unhurt data-hiders and enough single data-hiders are placed at risk to potential harm, the original image can be recovered not any loss. This makes the original image’s preservation stronger. We offer two coupled scenarios and two different cases for one of the proposed paradigm’s four potential uses. We create a separable RDH-EI approach with enormous capacity depending on the suggested model. The experimental outcomes demonstrate the effectiveness of the suggested approach.
