| Abstract: | This paper proposes a novel application of an on-line signature verification system to embedded OS, such as personal digital assistant (PDA). When PDA starts up, the system can function automatically for user authorization. As far as is known, PDA holds an embedded OS and a limited memory. Accordingly, it selects modified dynamic time warping (DTW) as a matching algorithm and extracts position and velocity as features. Preliminary experimental result looks encouraging. |
