A dedicated hardware for fingerprint authentication

Biometric systems are defined as systems exploiting automated methods of personal recognition based on physiological or behavioural characteristics. Among these, fingerprints are very reliable biometric identifiers. Trying to fasten the image processing step makes the recognition process more efficient, especially concerning embedded systems for real-time uthentication. In this work we propose an FPGA-based architecture that efficiently implements the high computationally demanding core of a matching algorithm.
