Abstract
A data processing system is disclosed which is equipped with a secure user friendly input system. The input system comprises an array of horizontal and vertical conductor supported on a flexible, transparent overlay membrane secured to the viewing surface of the display of an individual workstation and a remotely sensed personal stylus. The stylus is equipped to receive electromagnetic signals from the array and transmit signals containing information concerning the stylus position on the overlay and stylus ID to a receiver at the workstation. The input system also includes a control processor operating in stored program instructions which control the detection and log-on procedures for the remotely sensed personal stylus.
