In this paper, the authors propose a highly secure secret sharing scheme for multimedia image communication. The proposed scheme may used for generation of n number shares of a secret image. Both the construction and revealing of shares are based on LSB subtraction. In previously proposed schemes were surfers from several problems. Like in case of images having completely single color other than the color black, the shares were having strip patterns rather than being random or pixel expansion. The proposed scheme is applicable for any size of image, has no pixel expansion and can reconstruct the secret image precisely.
