摘要
信息隐藏技术已经成为近年来的研究热点,而音频信息隐藏更是这热点中的重点。利用该技术可以在音频文件中嵌入秘密信息以实现"隐秘通信"和"版权保护"。该技术的工作原理是基于人类听觉系统的特性和隐藏数据的几个基本要求的。迄今为止该技术还正处于发展中,已经提出了一些方法,这些方法都各具优势和劣势,还不成熟。
Information hiding technique has become research hotspots in recent years and audio information hiding technique is the focal point of it.With such techniques we may embed secret information into audio files,so as to get'covet communication'and'copyright protection'.The principles of this technique are based on the characteristics of human audio system and requirements of data hiding.so far,Some algorithms about the technique have been advanced,but they are not consummate and need to be developed.
