This paper is theoretically to prove that our proposed IIDH (image interpolation based data hiding) schemes have the better stego image quality than Jung and Yoo's IIDH scheme. Jung and Yoo's IIDH scheme is very cost-effective, so we use simple addition approach such as LSB substitution and OPAP to enhance PSNR of stego image. We analytically estimate PSNR of three IIDH schemes: Jung and Yoo's IIDH scheme, the proposed IIDH scheme using LSB, and the proposed IIDH scheme using OPAP. The proposed IIDH scheme using OPAP has the same embedding capacity of Jung and Yoo, and meanwhile has the higher PSNR than that of Jung and Yoo's IIDH scheme.
