Thumb Impression Operated Locking System for Multiple User

The use of fingerprint identification has been employed in law enforcement for about a security. A fingerprint locking system using picmicrocontroller uses fingerprint recognition system as a process of verifying the fingerprint image to open the electronic lock. This research highlights the development of fingerprint verification system using PIC18F4520 Verification is completed by comparing the data of authorized fingerprint image with incoming fingerprint image. The fingerprint image will first go through the data base and filtering process es through which the information about it is obtained. Then the information of given fingerprint image will undergo the comparison process to compare it with authorized fingerprint image. In this system, the fingerprint module has trained to learn and identify whether the incoming fingerprint image is genuine or forgery. A much broader application of fingerprint is for personal authentication, for instance to access a computer, a network, an ATM-machine, a car or a home.
