Authentication of individuals is rapidly becoming an important issue. The authors have previously proposed a pen-input on-line signature verification algorithm incorporating pen-position, pen-pressure and pen-inclination trajectories. This paper proposes an algorithm with three new features: (i) Incorporation of pen-velocity trajectories, (ii) A new distance measure between two signatures, and (iii) A new efficient algorithm for computing the distance measure. Preliminary experimental result looks encouraging.
