摘要：This paper proposes a data hiding method by secret sharing. The proposed method embeds a k-bit secret digit in a secret message (i.e., a bit stream, a secret image) into a cover pixel of a grayscale cover image at a time by generating two shadow pixels. The two shadow images produced by the proposed scheme are meaningful. The experimental results show that the proposed scheme achieves good visual quality of shadow images at various hiding capacities. Furthermore, after the secret message has been losslessly extracted, the original cover image can be completely restored pixel by pixel. ? 2009 IEEE.
