The aim of this research is to propose a novel method for Reverse Data Hiding (RDH) based on the Knight's tour algorithm, and to implement it using MATLAB 2013a version for encryption and decryption. RDH is a technique of embedding data into an image in a way that the original image can be restored without any visual distortion. The proposed method exploits the properties of the Knight's tour algorithm, which is a mathematical problem that involves finding a sequence of moves of a knight on a chessboard such that the knight visits every square exactly once. The proposed algorithm uses the Knight's tour to generate a sequence of indices that correspond to the pixels of the cover image, and uses these indices to embed the secret data. The proposed algorithm is evaluated using various metrics such as Peak Signal to Noise Ratio (PSNR) and Mean Square Error (MSE), Root Mean Square Error (RMSE) to measure the quality of the stego image. The results show that the proposed method achieves high levels of security and invisibility, and can be used for various applications that require secure data transmission and storage.
