Visual secret sharing (VSS) scheme is an image sharing scheme that divides a secret pixel into several sub pixels (the number of sub pixels is called the pixel expansion) and the secret image is visually revealed without additional computations. However the contrast of recovered image is poor and thus the VSS framework is always a research issue and not a practical scheme. In this paper, we introduce a new framework which prioritizes the pixels with different pixel expansions to reconstruct a high-quality image for practical use. Also, integrating the optical character recognition with the proposed VSS scheme we show a new automated visual authentication scheme.
