A Secret shearing Algorithm based on LSB Substitution

This paper proposed a highly secure secret sharing scheme for mul-timedia image communication. The proposed scheme may used for generation of n number shares of a secret image. Both the con-struction 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 applica-ble for any size of image, has no pixel expansion and can recon-struct the secret image precisely. The proposed scheme includes no matrix multiplication for construction of shares with computa-tional complexity equal to LSB method. The scheme can be di-rectly applied for any of the binary, grayscale or color image. Ex-perimental results show that the scheme is simple and effective
