Abstract :
A new fingerprint identification scheme is proposed for a single-chip fingerprint sensor and identifier. In this scheme, the identifying circuit is composed of a pixel array, and this circuit can correct the deviation of the sensed image´s location and compare the images by using the parallel processing of these pixels. Applying this circuit to a single-chip fingerprint sensor and identifier confirms 100-ms 6.2 mJ fingerprint identification. This scheme realizes the fingerprint identification system on a single chip
