A keyboard for cooperation with a keystroke and behavioral biometric analyzer, including a blank translucent surface for use as an input device, a capacitive layer mounted underneath the translucent surface, for enabling detection of touch location and touch pressure on the translucent surface, a projection system for dynamically projecting a visual layout of keys of a keyboard on the translucent surface, and a biometric generator, coupled with the capacitive layer, configured to receive user input in conformance with the projected layout of keys, and to generate therefrom a time series of touch location and touch pressure data, for use as data by a keystroke and behavioral biometric analyzer.
