| Research Abstract |
Multi-modal person authentication algorithm based on signature writing behavior was developed in this study. The developed algorithm uses not only pen tip trajectory (online signature), but also dynamic pen-holding style information, which includes how to hold a pen, and how to move a pen using a hand. These information can be extracted from a signature writing image sequences captured by a single camera. Therefore, we can improve recognition accuracy without increasing data capturing sensor. We analyzed the image sequences and extracted useful features for person authentication. Combination of these extracted features improves authentication accuracy.
