Secure Multi-Party Computation with Robust Reversible Watermarking in Encrypted Images Using AES Cryptosystem

Reversible watermarking research has increasingly concentrated on enhancing its robustness to resist attacks during digital media transmission because of the increasing development of network media. In reversible watermarking, the important components are the watermark's durability and the cover image's ability to maintain secrecy. In this paper, a secure multi-party computation (MPC) with robust reversible watermarking in encrypted images is proposed. We can share any text information embedded in an image by encrypting the image with a secret key, and then only the authorized user can access the data. The Pixel Repetition Method is used to perform pre-processing on the image after it has been taken as input. Payload capacity, visual quality, and attack protection are increased by the LSB information hiding algorithm of images using a secret key. It combines information hiding and cryptography to increase security and identity authentication based on digital signature and encryption technology. Its premise is the receiver's extraction of concealed data using the reverse process of System. Finally, through the safety and PSNR (peak signal-to-noise ratio) comparison experiment, the enhanced LSB image steganography algorithm makes use of encryption technology and is better than the standard LSB image steganography method in terms of security and PSNR.
