A hand-held device having a body with a pressure-sensitive exterior surface. At least a portion of the pressure-sensitive exterior surface is designed to be grasped by a user's hand. The pressure-sensitive surface contains a plurality of pressure sensors operative to provide an output signal proportional to a pressure applied by the user's hands to the exterior surface of the hand-held device at the area the pressure sensor is located. The device also includes a memory for storing the output signals provided by the plurality of pressure sensors and a processor for comparing the output signals provided by the plurality of pressure sensors against stored pressure profile signatures for positively identifying the user.
