“…, N is the discrete time index given by the acquisition device and N is the time duration of the signature in sampling units. Although pen inclination trajectories have shown some discriminative capabilities in other works (Hangai et al, 2000;Sakamoto et al, 2001;Pacut and Czajka, 2001), the use of these two functions in our system degrades the verification performance (as it is shown in Section 4.4.1). As a result, the basic function set consists of x n , y n and p n .…”

“…As a result, some researchers have stopped using pen pressure, [15], pen altitude, and pen azimuth [16] or have expressed concern about using pen inclination features [17]. On the other hand, some researchers have proposed algorithms taking account of pen inclination features and reported improved performance [18]- [20]. We also reported improved performance using pen pressure and inclination features [14].…”

“…The pressure measure is either taken at the pen tip [2,14] or by four sensors in each corner of the writing tablet [5]. However, the underlying authentication algorithms are proprietary and cannot be evaluated.…”

“…Besides handwriting digitizing devices that deliver signals for writing position and pressure, new approaches are described in [10,5]. Signals are being sampled using either force / acceleration sensors [10] or by calculating the pen angle using pen height and position at the pen top [5].…”
