Conventional (t, n) secret image sharing schemes share a secret image to n shared images, where any t shared images recovers the secret image. Among these shared images, noise-like properties easily draw attacker attention. Embedding shared images in meaningful cover images thus efficiently reduces attacker attention. This paper presents a different-expansion technique based invertible secret image sharing scheme that allows participants to perfectly restore the secret image and cover images. The proposed scheme also contains a lossy property which means that cover images do not have to be perfectly recovered to share larger secret images. The proposed scheme performs well with M-ary number systems, allowing users to determine the trade-off between covered image quality and secret image size. Experimental results show that the proposed scheme shares a large secret image and has good covered image quality.

“…The essential idea is to use a polynomial function of order k -1 to construct n image shares, in which the size of each share image is only 1/k times of the original image, but the computational complexity is the same as in Samir's scheme. This work attracted many researchers to propose different techniques which are given in references [4][5][6][7]. But in [3] T h i e n and L i n proposed a method in which the pixels having a value greater that 251, are truncated into 250.…”

“…In the scheme, the size of generated shadow images is only 1/r of that of the original image, which is advantageous in subsequent storage and transmission. Following the work of Thien and Lin, certain image sharing schemes [4][5][6] have been proposed to reduce the size of the shadow images.…”

In this study, a new (r, n)-threshold secret image sharing scheme with low information overhead for images is provided, which has a low distortion rate, and is more applicable for light images. A secret image is encoded into n noise-like shadow images to satisfy the condition that any r of the n shares can be used to reveal the secret image, and no information on the secret can be revealed from any r -1 or fewer shares. The size of the shadow images is relatively small. The experimental results show the effectiveness of the proposed scheme.
