Efficient high payload and Randomly selected sub-blocks image Steganography.

It has been a hot area of research in information and network security in which steganography has an efficient high payload and can hide much information.ERS(an Efficient high payload and Randomly selected sub-blocks image Steganography)is proposed.The experiment results show that the method can not only reduce change of cover image,but also improve the efficient high payload.ERS is simple.Its performance is better than others in the efficiency and security of information hiding.
