Authentication system and method for vehicles

A method for accessing a vehicle and/or a function of the vehicle, the method comprising: - illuminating the object with patterned infrared illumination; - generating at least one pattern image of the object while the object is being illuminated by the patterned infrared illumination; - determining if the object corresponds to a living human based the at least one pattern image; and - allowing the object to access the vehicle and/or the function of the vehicle based on de- termining that the object corresponds to a living human.
