Abstract: 隐密技术是指将信息隐藏于其他载体之中并应用于秘密通信的技术。作为其对抗技术，隐密分析是指用于检测、分析甚至破译互联网上隐密信息的技术。为设计高精度JPEG图像定量隐密分析算法，将定量隐密分析看成多元函数拟合问题，利用能有效反映DCT系数相关性的共生特征度量不同秘密信息嵌入量下的数据变化，并应用支持向量回归技术拟合25维共生特征与秘密信息隐藏量之间的函数关系，提出新的定量隐密分析模型。实验结果表明，本文模型对JSteg、F5、Outguess、MB1四种典型JPEG隐密算法均可设计出较高精度的定量隐密分析算法，且定量隐密分析性能远优于已有同类算法。
I am not a star professor, but I am working on the road to a star professor of tomorrow. For this reason, self-motivated graduate students are desired to my research group. Self-motivated attitude and initiative are the most important characteristics in our laboratory. Students with preliminary knowledge on signal (image/video) processing and programming skills are most welcome. For your academic trip in my group, I will devote myself to training your FIVE abilities: Intellectual skills, Communication skills, Personality characteristics, Habit of work, Mechanical skills, which are considered as the most important abilities of a graduated student.
