Secret Color Images Sharing(2,n)-Threshoid Scheme with Multiple Shares
Dongmei Niu · Information Security and Communications Privacy · 2009
A secret color images(2,n)-threshold scheme based on XOR operation is proposed in reference[2].The algorithm of this scheme is very simple and easy to implement,and however,the quality of the recovered image is not so satisfactory.In this paper,the reason of distortion is discussed first,and then a secret color images sharing(2,n)-threshold scheme with multiple shares is presented.In the scheme,more shares are distributed to participants,thus to improve the quality of secret image recovering.Experiments and analysis indicate that the proposed scheme could improve the quality of recovered image while maintains the security and simplicity of the algorithm.
