Abstract

This paper deals with a modified method of the dynamic time warping and feature points to extract various important information of the signature for the dynamic signature verification. We could achieve lower equal error rate, small and efficient feature points and fast processing time for the notification.

본 논문에서는, 동적 서명의 여러 가지 중요한 특징을 잘 반영할 수 있는 특징 정보를 추출하였고, 두 패턴을 비교하는 방법에서는 기존의 DTW 방법에서의 문제점을 개선하여 제안된 DTW 방법을 사용함으로써, 낮은 오류율(본인 거부율, 타인 수락률), 적은 량의 특징 정보, 빠른 처리 속도 등에서의 성능을 개선하였다.
