Abstract:
A system for managing handwritten signatures, comprising:(a) a graphic tablet for signaling position coordinates of a stylus during manual movement thereof relative to a writing surface;(b) a clock circuit for periodically initiating position measurements by the graphic tablet at predetermined fixed time intervals;(c) a first computer processor electrically interfaced with the tablet, the processor being programmed for receiving a multiplicity of the coordinates during the manual movement of the stylus, and storing respective sets of the coordinates in sequential order as an electronic signature while preserving a time relation between coordinates, the electronic signature forming a time history of the stylus movement; and(d) means for comparing the electronic signature with a reference signature, comprising the computer processor having a graphic display implemented for simultaneously displaying the electronic signature and the reference signature with corresponding cursors being positioned along a line segment of the signature and oriented perpendicular to the line segment, and the computer being further implemented for moving the cursors in response to operator input.
