An Analysis of Reversible Data Hiding Techniques in Images

Abstract

The reversible data- hiding fashion conceals some sensitive information in an image for secure communication. Only an authorised party may decrypt the concealed communication and recreate the cover image. The strategies put forth by different experimenters haven't yet been suitable to reflect a picture with a high embedding rate and advanced reconstructed image quality. In this exploration, certain significant reversible data- caching strategies are addressed and a system is proposed that can enhance the quality of the reconstructed image, the embedding capacity, and the denoising of the image. This approach can offer a secret data transfer that's further authentic, private, and dependable. Keywords: Embedding rate, Encryption, Prediction error, PSNR, Reversible data-hiding, Steganography
