Proposal of New Security System Using the Three-Dimensional Motion of the Finger

Abstract

In this paper, we propose a new authentication system that uses the motion of finger tracing a three-dimensional (3D) object by using 3D motion capture and 3D scenography. Specifically, it captures the 3D motion of a finger tracing a 3D object displayed on a 3D monitor, and carries out verification by comparing previously registered data with the captured data obtained from the 3D motion of the finger. As a first fundamental step in the development of this authentication system, an exploratory experiment was conducted using 3D scenography constructed by augmented reality (AR) projected onto a normal 2D monitor.
