摘要
提出了一种针对JPEG图像Jsteg信息隐藏的改进算法。详细地介绍了JPEG图像Jsteg信息隐藏算法的理论和原理,针对该算法的不足提出了一种改进的算法,这种改进的算法能在极好地保持JPEG图像DCT系数中0的统计特性的同时,让系数0也能够携带秘密信息,从而增大了JPEG-Jsteg密写算法的嵌入量。
This paper presents an improved algorithm based on the JPEG-Jsteg information hidden and describes the principles and theories of the JPEG images Jsteg information hiding algorithm, an improved algorithm for the deficiencies of the algorithm, this improved algorithm can be excellent to maintain the statistical properties of the DCT coefficients of JPEG images while factor capable of carrying the secret information, thereby increasing the steganography algorithms in the JPEG-Jsteg embedded.
