Flick Authentication



Physical biometrics technologies are introduced to the login process on smart devices. However, many of them have several disadvantages: requirement of embedding special sensor, limited environment to use and copy of key information for authentication. In this research, we proposed, Flick Authentication, a new biometrics technique which can capture user's inimitable behavioral features in his/her spontaneous flick reactions on a touch-screen display for unlocking the device when it wakes up.


Intelligent Systems Science Lab, University of Hyogo [4/2014 - 3/2018]
  • Project Researcher [4/2016 - 3/2018]
    Student Researcher (as Master's Student) [4/2014 - 3/2016]
  • Advisor: Prof. Haruhiko Nishimura (Graduate School of Applied Informatics, University of Hyogo)

  • Developed a new biometrics technique with captured behavioral features in spontaneous flick reactions on a touch-screen display for screen unlocking. Patent pending.
