About Me

I'm currently a final-year Ph.D student 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.

Before I joined HKUST as a Ph.D student, I received my MPhil degree in Computer Science from Hong Kong University of Science and Technology(HKUST) in June 2013, and B.S degree in Computer Science from South China University of Technology (SCUT) in June 2008.

Research Interest

My research topic is security design for mobile systems. I mainly focus on building security systems/applications for mobile devices by leveraging physical/biological data analysis. I'm also interested in big data analaysis in moible networks, and QoE-based video-streaming optimization.

Recent Work

Secure Pairing through EMG, SenSys'16

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.
