Secret sharing is an alternative method for protecting an image by dividing it into multiple encrypted shares. When sufficient shares are collected, the image can be losslessly recovered. In this paper, secret sharing is adopted to reversible data hiding in encrypted images. A basic model by using secret sharing for reversible data hiding in encrypted images is firstly introduced. Then, an image encryption...
