Abstract
Image Steganography is one of the most well-known methods where a top-secret data is embedded into the pixels of an image by altering some of its pixel values. Reversible Image Steganography is used extensively due to its property of reconstructing the original cover image without any loss. Various studies have been conducted to achieve stego image with high Embedding capacity, less time complexity, high imperceptibility, and robustness. Keeping the necessary parameters under consideration, we conducted our study on Reversible Image Steganography to achieve better Peak Signal to Noise Ratio (PSNR) value or high Embedding capacity which helps us in analyzing the quality. We have analyzed PSNR ratio and compared it with the standard tests ensuring the quality of the embedded image. Also, we have provided an overview of numerous Reversible Picture Steganography techniques based on compression, encryption, higher capacity, quality, and performance.
