Current Research

    Implicit Authentication

  1. My current research focuses on the structural improvement of implicit authentication, e.g, how to improve its authentication accuracy and EER given multiple sensors. My research not only uses just one or two sensors in the smart devices but considers all the sensors available in the device. Since it is a general improvement, my research can be applied to many different schemes proposed by other researchers, e.g., gait-, touch-, and lighter meter-based user authen tication.

  2. I am also interested in the user identification using behavioral data and related techniques. In my recent resaerch, some techniques in psychology have been adopted to improve the accuracy of the authentication system.

    Cloud Security

  1. My research in cloud security mainly focuses on DDoS attacks and associated defense mechanisms. Currently, my research aims to provide a robust system that can protect the cloud from various attacks using a botnet.
