ABSTRACT:
A fingerprint input apparatus includes an image sensor which responds to scattered light emanating from a finger. The scattered light is generated inside a finger having a fingerprint pattern in accordance with external light. The sensor may be a two-dimensional image sensor made of a large number of light-receiving elements arranged in a two-dimensional array or a one-dimensional sensor made of a large number of light-receiving elements arranged in a line-type array. In the latter case, the fingerprint is input by swiping the finger across the image sensor and reconstructing the fingerprint image. The fingerprint input apparatus is used to control use of a variety of devices, including electronic devices such as cellular telephones and personal computers, and access to buildings, rooms, safes and the like. The fingerprint input apparatus makes possible the elimination of personal identification numbers (PINs) and signatures in a variety of transactions.
