摘要
In this study, a new (r, n)-threshold secret image sharing scheme with low information overhead for images is provided, which has a low distortion rate, and is more applicable for light images. A secret image is encoded into n noise-like shadow images to satisfy the condition that any r of the n shares can be used to reveal the secret image, and no information on the secret can be revealed from any r - 1 or fewer shares. The size of the shadow images is relatively small. The experimental results show the effectiveness of the proposed scheme.
