A pixel contractible secret sharing scheme(2n,2n)based on Boolean operation and Arnold tronsform is proposed to decrease the burdens of participants.This scheme divides an image into 2npieces(shares)in such a way that each piece has the size of 1/2nof the original image and only all shares are available can we restore the original image without any quality loss.Comparative study shows the effectiveness and performance of the proposed algorithm.
