Yang and Ciou recently proposed a two-in-one image secret sharing scheme (TiOISSS), which can easily preview a vague image by human eyes, but also provide a perfect reconstruction of the original image by computation. However, their scheme cannot recover the lossless image by computation as they claimed. In this paper, we resolve the problem of lossless reconstruction. In addition, we improve the visual quality of the previewed image. Also, we introduce a new definition of contrast to evaluate the visual quality of the previewed image. Compared with Yang and Ciou’s TiOISSS, our scheme can gain the lossless secret image and meantime enhance the contrast of previewed image.
► Pointing out two weaknesses in Yang and Ciou’s TiOISSS.
► Proposing a lossless TiOISSS.
► Proposing an enhanced scheme to improve the visual quality of the previewed image.
► Introducing a new definition of contrast to evaluate the visual quality.
