Aiming at the encryption of the secret information in image steganography scheme
the article applies Kerckhoffs’ principle in image steganography.Based on the comparison between encryption and steganography
the article analyzes the importance of Kerckhoffs’ principle.In order to reduce the exposure probability of the stego
the secret information is hidden in a set of cover-images.The scheme uses encryption arithmetic to resist the attackers’ cryptanalysis.Analyses show that the image steganography scheme introduced in this article can improve the security of the image steganography scheme and keep the information secret.
