摘要
信息隐藏是一门正在迅速发展的学科,广泛应用于秘密数据通信、知识产权保护等领域。从音频信息隐藏MP3Stego出发,分析了各种MP3Stego的检测攻击技术,然后通过对MP3Stego隐藏特性的研究,提出了一种检测MP3Stego的新方法。这种方法通过计算MP3文件中part23、stuffingBits的统计量,可以准确检测出经过MP3Stego处理的MP3文件。实验证明,该方法简单有效,可以用于实现MP3Stego信息隐藏的检测。
Information hiding is the art and science of communicating in such a way that the presence of a message cannot be detected. It can be used for secret communicating and copyright marking and receives more attention from the research community and from industry today. This paper introduced the audio information hiding techniques first, with an emphasis on MP3Stego, then introduced the existing MP3Stego attacking and detecting techniques. After analyzing the properties of MP3Stego, a new detecting method was found. This method can detect mp3 files produced by MP3Stego correctly by calculating the statistic of part23 and stuffingBits in mp3 files. The experiments proved that this method is effective and can be used to detect MP3Stego.
