1. A live human detection system, comprising: a camera for capturing a plurality of current images of a human subject; a data storage device for storing a plurality of stored images of the human subject, each stored image including at least one of features of at least one eye of the human subject and data created from an image of at least one eye of the human subject; a subject identification device; and a processor coupled to the data storage device, the camera, and the subject identification device, the processor including instructions which, when executed by the processor, cause the processor to: receive a subject identification from the subject identification device; capture a plurality of current images from the camera, those images including at least one initial image, at least one intermediate image, and at least one later image, where at least one of the plurality of current images can be both an initial image and an intermediate image and at least one other of the plurality of current images can be both an intermediate image and a later image; convert each of the plurality of current images received from the camera to greyscale if the plurality of current images are in color; detect at least one of the eyes of the subject in each of the plurality of current images; determine whether an ocular region including one of the detected eyes in the at least one initial image matches a corresponding open eye in at least one of the stored images of the subject; determine whether an ocular region including one of the detected eyes in at least one intermediate image matches a corresponding closed eye in at least one of the stored images of the subject; determine whether an ocular region including one of the detected eyes in at least one later image matches the corresponding open eye in at least one of the stored images of the subject; and conclude that the subject is live and an approved subject if the ocular region including the at least one eye in the at least one initial image matches the corresponding open eye in at least one of the stored images of the subject, the ocular region including the at least one eye in at least one intermediate image matches a corresponding closed eye in at least one of the stored images of the subject, and ocular region including the at least one eye in at least one later image matches the corresponding open eye in at least one of the stored images of the subject.
