FINGER PRINT BASED ACCESS CONTROL SYSTEM
ABSTRACT:
According ancient Greek scripts BIOMETRICS means study of life. Biometrics studies commonly include fingerprint, face, iris, voice, signature, and hand geometry recognition and verification. Many other modalities are in various stages of development and assessment. Among these available biometric traits Finger Print proves to be one of the best traits providing good mismatch ratio and also reliable. The present scenario to operate a bank locker is with locks which are having keys. By this we canâ„¢t say that we are going to provide good security to our lockers. To provide perfect security and to make our work easier, we are taking the help of two different technologies viz. EMBEDDED SYSTEMS and BIOMETRICS. Firstly discussing about Biometrics we are concentrating on Fingerprint scanning. For this we are using FIM 3030N high voltage module as a scanner. This module has in-built ROM, DSP and RAM. In this we can store up to 100 users fingerprints. This module can operate in 2 modes they are Master mode and User mode. We will be using Master mode to register the fingerprints which will be stored in the ROM present on the scanner with a unique id. When this module is interfaced to the microcontroller, we will be using it in user mode. In this mode, we will be verifying the scanned images with the stored images. When coming to our application the images of the persons who are authorized to enter into the room will be stored in the module with a unique id. To prove that the persons are authorized to enter that area they need to scan their images. scanner is interfaced to 8051 microcontroller. By using this controller we will be controlling the scanning process. After the scanning has been completed the door automatically unlocks with the help of electric lock. If an unauthorized person tries to scan his image then the door doesnâ„¢t opens for him. The project uses regulated 5V, 500mA power supply. 7805 three terminal voltage regulator is used for voltage regulation. Bridge type full wave
