I am a Ph.D. student at the University of Wisconsin-Madison, majoring in computer engineering. My advisor is Prof. Younghyun Kim at the Wisconsin Embedded Systems and Computing (WISEST) Lab. I also actively work with Prof. Fawaz at WI-PI on various research challenges in the security & privacy of IoT and human-centered applications. My page at WISEST Lab can be accessed through this link.
Living with my childhood dream, I enjoy inventing, designing, and building ‘future gadgets’ that serve user needs by unconventional computing techinques and devices.
We are seeking to bridge the gap of user privacy in human-centered sensing. Eye tracking enables a more immersive experience for today’s user interface, while its rich information is exposed, inducing privacy concerns about users’ interest, health, identity, etc. Through the on-going project, we are exploring the opportunity to design real-time privacy control knob for eye-tracking in mixed-reality.
We developed a novel solution, Velody, for user authentication in smart homes using unique vibration responses from users’ hands. Thanks to the nonlinear properties in hand-surface vibration, Velody can generate a large number of secret keys resilient to various attacks and accurately authenticate users in less than one second. This work is presented at ACM CCS 2019.
