Abstract

Digital image steganography suffers from poor security and small embedded capacity.Based on Bernstein polynomial transform and K-L divergence

a batch steganographic algorithm for image sharing was proposed to achieve double covers information hiding.Bernstein polynomial and the approximation of nth operator was proved

relationship between maximum payload of sharing image and sharing operator was obtained

and security constraints of batch stegosystem were discussed.The approach to image sharing and recovering was studied completing image sharing in decomposed sub-graphs.The security of the algorithm was analyzed.The experimental results showed that the steganographic method satisfies Cachin's definition of security.
