A study on Automatic Parameter Estimation Method for Continuous Authentication Algorithm DPTM

Abstract

In this paper, we examined the optimal class interval width for each user in order to auto- matically estimate the class interval width that determines the probability used in the DPTM continuous authentication algorithm. In the experiment, we performed the DPTM-based continuous authentication using multiple class interval widths, and examined whether the class interval width with the highest continuous authentication evaluation is different for each user. As a result, we found that the optimal class interval width differs for each user, indicating the importance of automatic estimation of the optimal class interval width.
