摘要 提出了一种新的图像隐藏方案,该方案糅合了多重秘密共享思想与LSB算法,生成的影子图像约为秘密图像的1/t,从而减小了载体图像的容量。本方案允许任意选取(t-1)次多项式的模数p,并根据该模数p将秘密图像的若干个像素点拼接成一个数据单元,有效克服了Thien方案中秘密图像需进行置乱处理的缺陷。此外,本方案构造的多项式明显少于Thien方案和LiBai方案。 Combining multi-secret sharing with Least Significant Bit （LSB） algorithm, a new image hiding scheme was proposed. This scheme reduced the size of each shadow image to become nearly 1/t of the secret image＇s, consequently reduced the size of cover images. According to （t - 1） polynomial modulus p which was arbitrary, this scheme spliced some pixels of the secret image into a data unit so that the drawback was overcome that the image should be permutated before it was shared. Besides, the amount of polynomials in this scheme is smaller than that of Thien＇s and Li Bai＇s.
