Abstract

In an embodiment, a method for authenticating a user of a car includes: transmitting a plurality of radiation pulses through a predetermined portion of a surface of the car towards a portion of a hand of the user using a millimeter-wave radar; receiving a reflected signal from the portion of the hand using the millimeter-wave radar; generating a fingerprint signature based on the reflected signal; comparing the fingerprint signature to a database of authorized fingerprint signatures; and authorizing the user based on whether the fingerprint signature matches an authorized fingerprint signature of the database of authorized fingerprint signatures.
