摘要：This paper proposed an improved data hiding steganographic scheme using Sudoku puzzle, which can be utilize to identify least distortion pixel value of selected pixel from the digital image with respect to secret digit. The scheme calculates three components for the selected pixel from the Sudoku puzzle based on the secret digit. The proposed scheme does not affect the visual quality of the stego-image. This work is simulated in the MAT LAB and presented results. The performance of scheme is compared with the existing methods with respect to image distortion. The quality of the steg-image is also verified using image assessment parameters PSNR and MSE.
