Touch panel with integrated fingerprint sensors based user identity management

In this paper, to enhance identity acquisition procedures in smartphones and make the process transparent to the user, a novel User Identity Sensing approach leveraging the unified fingerprint enabled touch panel that combines multiple capacitive TFT based fingerprint sensors directly with the touch screen panel of the smartphone is proposed. The solution passively fulfills mobile users identity management during natural user-device touch interactions and requires neither password nor extra actions from the user, which makes it highly user friendly. To demonstrate the feasibility of such a unified, user identity sensing based design, an investigation of the hardware metrics is performed. Simulation experiments are conducted to evaluate the system with touch data collected from 25 smartphone users. The resulting observations and simulation results provide guidance for an efficient design of the hardware and criteria that need to be satisfied for the development of an operational prototype.
