Authentication of individuals is rapidly becoming an important issue. This paper proposes a new nonlinear algorithm for pen-input on-line signature verification incorporating pen-position, pen-pressure and pen-inclinations trajectories. A preliminary experiment is performed on a database consisting of 1849 genuine signatures and 3174 skilled† forgery signatures from fourteen individuals. Since no fine tuning was done, this preliminary result looks very promising.
