We presents a novel (2, 2) secret sharing (SS) scheme for all grayscale images. Generally, a secret image is distribute more than two shadow images, which are dealt out among participants. In order to find out secret image, participants print shadow images to transparent papers. Then, a secret image will appear as stacking transparent papers. The secret sharing scheme in this paper distribute secret image into natural grayscale images using multiplexer and data hiding scheme. After then, two participant have two shadow images respectively. The merit of the proposed scheme is that shadow images have small loss in aspect of the quality with steganographic features. Therefore, the proposed secret sharing scheme in this paper is not easily detected by attackers. The experiment result verified that the proposed scheme, obviously outperforms previous SS schemes.

본 논문은 회색(Gray-scale) 이미지를 기반으로 (2, 2) 비밀 공유(Secret Sharing) 계획을 제안한다. 일반적으로 비밀 공유 방법은 비밀 이미지를 두개이상의 이미지 (그림자 이미지: Shadow Image)로 분배한 후, 그림자 이미지를 참가자(비밀 공유하는 사람)에게 나누어준다. 이 후 참가자들이 비밀을 보기위해 k(k
