隐写分析应用中的谱估计方法比较及性能分析
Spectral Estimation Methods Comparison and Performance Analysis on a Steganalysis Application
摘要：
隐写术是一门艺术和科学，它以一种除了预期的接收者之外没有人知道消息的存在的方式编写隐藏的消息。在当今世界，它被广泛用于保护信息。本文介绍了传统的谱估计方法。通过比较所有的谱估计方法，每个方法的性能分析进行检查。最后，利用这些性能分析，简要的频谱估计方法的优点和缺点。我们还给出了一个将信息隐藏到声音信号中的隐写演示，并通过频谱估计方法从声音中提取信息（即信息信号的真实频率）。
英文摘要：
Steganography is the art and science of writing hidden messages in such a way that no one apart from the intended recipient knows of the existence of the message. In today's world, it is widely used in order to secure the information. In this paper, the traditional spectral estimation methods are introduced. The performance analysis of each method is examined by comparing all of the spectral estimation methods. Finally, from utilizing those performance analyses, a brief pros and cons of the spectral estimation methods are given. Also we give a steganography demo by hiding information into a sound signal and manage to pull out the information (i.e, the true frequency of the information signal) from the sound by means of the spectral estimation methods.
