摘　　要：作为信息安全保护和版权保护的重要手段,信息隐藏技术在20世纪后得到了迅速发展,目前可大致分为两种类型:可逆信息隐藏和不可逆信息隐藏。本文总结了信息隐藏技术及其发展脉络,并对多种信息隐藏算法进行性能分析,就三种不可逆算法——LSB算法、NEC算法、DCT算法,和两种可逆算法——像素直方图平移算法、相邻像素差构造直方图算法,共五种算法采用定量分析方式进行算法性能的探究,并对五种算法的不可感知性、鲁棒性和信息容量进行纵向比较,探究实现可逆信息隐藏的代价。As a necessary approach of information security and copyright protection, information hiding technology has developed rapidly since the 20th century, and can be roughly divided into two types: reversible information hiding and irreversible information hiding. The paper summarizes the information hiding technology and its development, and mainly analysis the performance of five information hiding algorithm, which contain three kinds of irreversible algorithm-the LSB algorithm, NEC and DCT algorithm, and two reversible algorithmpixel histogram translation algorithm, adjacent pixel difference histogram construction algorithm. In this paper, quantitative analysis is adopted to compare the performance of the algorithms by longitudinal measurement of imperceptibility, robustness and information capacity, and explore the cost of realizing reversible information hiding.
