In this thesis, we implement a fingerprint identification system using a digital signal processor (DSP). First, we perform computer simulations on the adopted fingerprint verification algorithm. Two sources of fingerprint images were tested, the first set is adopted from the database of Fingerprint Verification Competition 2000(FVC2000). The second set is acquired by the sensor LTT-C500 manufactured by LighTuning Tech. Inc. Because of its fillister design which puts natural constraint on the position of the finger so that the errors incurred during the acquisition process are minimized, the identification rate has been greatly improved. Next, the acquired fingerprint images which are of size pixels are transmitted following the serial transmission protocol to the SDRAM of the DSP. After the processes of preprocessing, feature extraction, and matching, the results are shown on a LED where the green light and the red light indicate success and failure of the fingerprint identification task, respectively. Experiments demonstrate that the feasibility of the implemented fingerprint identification system.
