The author introduces the LSB algorithm and Logistic mapping principle,and proposes a new improved algorithm for hiding LSB image information.This algorithm uses the chaotic characteristics of logistic mapping to scramble the image,and uses the logistic parameter u to make the image generate two sequences.Then,operation and the secret information comparison are implemented to determine whether to modify the LSB bit to realize steganography of the information.The algorithm makes full use of the image pixel high bit information and has strong adaptive ability.The experimental results show that t...
