Patent attributes
The organism authenticating apparatus 71 of this invention comprises a means that fixes the position of a hand or a finger of a hand, an infrared ray radiating means 97 that radiates infrared rays, an infrared ray image input means 91 that is placed at the opposite side of said hand or said finger of a hand with regard to said infrared ray radiating means, an organism recognizing means that recognizes that the organism is live, a processing means that processes data that are inputted by said infrared ray image input means so that it collates them with image data that are registered in advance and an output means that outputs the result of processing carried out by said processing means. By using this invention, it becomes possible to obtain a clear blood vessel pattern image by a compact size apparatus by using an infrared ray source and by capturing the passed-through infrared ray image of the organism, and it becomes possible by using an organism recognizing means to prevent false authentication.
