Abstract

reversible data hiding, or RDH for short. Within the scope of this paper, we provide a high-capacity RDH-EI method that uses embedding on so many layers. In most cases, it involves three distinct players: the receiver, the info hider, and the material owner. The image has been scrambled inside its original form by the owner of both contents using data encryption. After encryption, there is still the potential for the one who hid the data or the cloud owner to insert extra data into it. The embedded information and the reference image could be retrieved without any loss on the receiving end. This part of the study proposes a method for encrypting images based on a rotation and substitution cipher. During the permutations step, the image's pixels are muddled using the Gingerbreadman map. During the replacement stage, the image's pixels are bit-wise XOR-ed with the output sequence generated by the Rivest Cipher 5 (RC5) stream cipher method. Unaware of the original image's information, the encryption process can insert private documents into image disparities reversibly via a modification to the two-dimensional difference histogram. Furthermore, the information collection and the image restoration processes are absolute, with no error. The outcomes of the investigations prove that the strategy can be implemented effectively and successfully. There are additional security evaluations discussed in this study, including key sensitivity.
