Biometric Authentication System Using Fingerprint Identification

Security has became the fundamental research field now a days. Finger print, iris, face, speech are the fundamental parameters that can help in designing a biometric authentication system. These kinds of systems are helpful in recognizing the identity of the authenticated person. The finger print based biometric authentication system is the most successful one due to simple nature of acquiring the image and uniqueness associated with it. An embedded system design that can acquire the finger print image, store on board level and allow the access to restricted resources is presented here. In this technique the first thing is the enrollment of the finger print and at the later stage authentication procedure is performed. The system is proposed to be designed with ARM microcontroller from Philips. The LPC2148 from ARM 7 series is a 32 bit microcontroller having capability of serial peripheral and UART interface for interfacing finger print sensor module. The optical finger print sensor module SM630 has been used. The finger print can be scanned and used to for the authentication of the person. E2PROM is used to store data of the person to be authenticated.
