About Me

I'm currently a postdoctoral fellow in Department of Computer Science and Technology, Hong Kong University of Science and Technology (HKUST). I work with Prof. Qian Zhang in Huawei-HKUST Invovation Lab.
I received my Ph.D. degree in computer science in Sep. 2017 and M.Phil degree in Computer Science in June 2013 from HKUST. Before that, I got B.S degree in Computer Science from South China University of Technology (SCUT) in June 2008.

Research Interest

I'm currently working on building mobile applications or security systems based on physical/biological data analysis. I'm also interested in big data analaysis in moible networks, and QoE-based optimazation.

Recent Work

Secure Pairing through EMG.

Electromyogram (EMG) is the electrical activity caused by human muscle contraction. The random and subtle characteristics of EMG make it an excellent source of secret key. We propose a system that can securely pair wearable devices by exploiting the EMG signal as random source. Extensive evaluation results indicate our system can provide a better security than existing pairing schemes and achieving a competitive secret bit generation rate of 5.51 bit/s while maintaining a success matching rate of 88.84%.

VibID: User Identification through Bio-Vibrometry, IPSN'16

VibID is a novel user identification for wearable devies, which uses a low-cost vibration motor and accelerometer to simulate an unobtrusive vibration to users’ arms and capture corresponding bio-responses. By exploring the body response to vibrations of different frequencies, VibID can distinguish users with an accuracy above 91% and is robust to various confounding factors.
