A secret image sharing scheme for light images
Kuang‐Shyr Wu · EURASIP Journal on Advances in Signal Processing · 2013
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.
