FINGER PRINT BASED ACCESS CONTROL SYSTEM
According to 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 can’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 the fingerprints of up to 100 users. This module can operate in 2 modes i.e., 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.
This application will be mostly used in organizations, banks etc. The persons who are the employees of that particular organization will be asked to scan their images for the first time they enter into the organization. After that, whenever the employee tries to enter into the organization, he has to scan his image to prove that he is an authorized person to the organization. Thus, the fingerprint module scans the image and sends it to the microcontroller. The microcontroller reads the image, compares the image with the already stored images in the database.
If the scanned image matches the stored image, the person is asked to enter the password using the keypad to enter into the company through the main door. This password will be provided to the employee by the company. If the password matches, the person is allowed to enter into the office through the main door. The main door will be opened by rotating the stepper motor fixed to it. The door closes automatically after a small delay. If it is not matched, indication is given to alert the buzzer.
APPLICATIONS OF FINGER PRINT:
- Secure logins via keyboard modules
- User identification at kiosks
- Biometric door locks
- Credit card security
- Weapon activation
- Theft protection
- KEIL COMPILER
- FINGER PRINT MODULE
- DOOR LOCKER
