结合快速编码的F5隐写算法改进
Improvement of F5 algorithm combined with fast coding
摘要
Abstract
Digital steganography is an important way for secret communication,and F5 steganographic algorithm proposed by Westfeld is an excellent steganography in DCT domain.The main steps of F5 steganographic algorithm is introduced,the matrix encoding and embedding process are analyzed.Its defects are pointed out and the caution is analyzed.Then the original matrix encoding of F5 steganographic algorithm is replaced by fast coding which has a lower rate of modification,and the original embedding process is also changed.Experiments show that the new improved algorithm has improvement in both security and capacity.关键词
