High-efficiency and Non-permutated Image Secret Sharing Scheme
Rui Guo · Jisuanji gongcheng · 2010
Aiming at the problem that the image should be permutated before it is shared,based on(t,n) threshold multi-secret sharing theory,a non-permutated image secret sharing scheme is proposed.It makes use of the n+1 participator’s secret shadow as a gene to participate in sharing and recovering.The gap between the adjacent pixels is increased effectively.This scheme doesn’t need added secret key transmission.It is easy to be extended and the size of each shadow image is reduced to 1/t of the secret image.Experimental result proves this scheme is feasible.
