Abstract:
An identity verification device for use with a computer-based system, the system being used in connection with an image that is generated on a reference surface by a user, the identity verification device comprising:a stylus including a tip operative to generate the image when contacting the reference surface, the stylus further including a fingerprint sensor operative to capture at least one fingerprint image of the user,a memory containing a first reference fingerprint image and a second reference fingerprint image, anda processor in electrical communication with the fingerprint sensor of the stylus and the memory, the processor generating a first identity verification signal responsive to a comparison of a first captured fingerprint image and the first reference fingerprint image,wherein the processor receives an instruction from the system to generate a second identity verification signal, the second identity verification signal being responsive to a comparison of a second captured fingerprint image and the second reference fingerprint image,a second fingerprint image sensor on the stylus in electrical communication with the processor, wherein the second fingerprint image sensor is positioned to capture a second fingerprint image during capture of the first fingerprint image by the first fingerprint sensor, and wherein the processor generates the identity verification signal based at least in part by comparing the second fingerprint image and a second reference fingerprint image.
