Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, we propose a new user authentication method based on statistical analysis of keystrokes. First of all, we measure the time a key pressed and the time a key released, and compute the feature of keystrokes using digraph (typing keys of two successive letters). Next, we sort the typing samples of the digraphs by their duration, and compare the sorted samples with the profile data collected in advance by using kendall tau rank correlation coefficient. We have performed experiments by this method and have attained good results.
