摘要： 在比较了当前各种经典音频隐藏算法的优缺点及其无法抵抗的攻击算法后，提出了一种非常有效的mp3 文件中隐藏秘密信息的算法，它将数据隐藏在一个复合空间内。和现有算法相比，它具有更高的隐藏率、健壮性和不可感知性，能有效抵抗统计攻击。

Abstract: After a comparison of modern audio steganography algorithms’ merits and demerits and their respective attack methods, this paper presents a highly effective algorithm embedding secret text in mp3 files by hiding the clandestine bit in a composite mode other than in the LSB of some variable. In contrast to the listed ones, the mp3hide puts up competitive robustness, imperceptibility, and hiderate and capability to be immune to statistics-based attack method.
