Research of spatial LSB-based detection of hidden messages LIU Qiong-qiong, PING Xi-jian (Institute of Information Engineering,Information Engineering University,Zhengzhou 450002,China) Abstract:Detection of hidden messages in images is foundation of steganalysis,which is of great importance for both the network information security and the improvement of security of steganographic algorithms. At the basis of steganographic algorithms based on spatial images ,this paper introduces the steganalysis principle and some detection methods ,then evaluates these methods.Finally,future direction in steganalysis development is pointed out,and prospect of
steganalysis is expected.
