Cheng Yushi


I’m a M.E. student in the College of Electrical Engineering, Zhejiang University. My research interests include usable security and privacy, biometric authentication and data mining. I prefer problems from the real-world. I tend to create unconventional solutions by identifying novel phenomenon and analyzing its underlying principles. I focus on personal privacy and, especially secret filming detection and prevention. I think it’s a serious problem at present and will keep working on it.
