摘要
信息隐藏和检测技术已日趋重要且应用广泛熏隐藏分析的目的在于检测媒体中隐藏的信息。本文针对JPEG图像文件的隐藏检测技术应用熏介绍了几种典型的隐写术的原理和弱点。通过对相关隐藏算法的研究分析熏讨论了基于统计特性的检测隐藏信息的方法熏并在结论中给出了相关的实验结果。
Techniques for information hiding and detecting have become increasingly more important and widespread. The aim of steganalysis is to detect messages hidden in media. For the application of detecting messages hidden in JPEG images file, the principles and shortcomings of several typical steganographic methods are discussed in this paper. Through researches of related hiding schemes, we discussed the approach of detecting stego information based on statistical feature and presented related experimental results in the end.
