This paper proposed 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

The proposed scheme includes no matrix multiplication for construction of shares with computational complexity equal to LSB method. The scheme can be directly applied for any of the binary, grayscale or color image. Experimental results show that the scheme is simple and effective.
