Abstract: Abstract This innovative reversible data-hiding algorithm ensures that The starting image could transform inton entirely restored by not visible distortion once the hidden data is extracted. The project specifically targets Invisible data infusion with reversible restoration utilizing advanced techniques like Improved Pixel Value Ordering and Pairwise PEE. This project, which covers photos, undergoes initial segmentation into a non-overlapping block of uniform size. Subsequently, within every block, pixels value an organized in increasing sequence. Using this ordered sequence, the second biggest or small pixels value predicts the large or small values, respectively, yielding two distinct prediction errors. These errors are subsequently utilized to construct the data embedding process for each block, ensuring effective concealment of information within the image. The system embeds secret data into images while ensuring high visual quality, offering a comprehensive performance evaluation. This method can be applied to various business applications where information hiding plays a crucial role.
