A Lossless Secret Image Sharing Scheme Based on Steganography

In this paper, a new lossless secret sharing method based on steganography is proposed. The new scheme generates shares from the cover image and secret image, and then embeds the shares into the cover image obtaining stego-shadow images based on 24-ary notational system. Experimental results have demonstrated that the proposed secret sharing scheme achieves high quality of the stego-shadow images and high embedding capacity. In addition, it can recover both the original secret image and cover image losslessly.
