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 can’t say
that we are going to provide good security to our lockers. To provide perfect
security and to make our work more easy 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
locker 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.
This scanner is interfaced to AT89S52
microcontroller. By using this controller we will be controlling the scanning
process. After the scanning has been completed the person has to enter the
unique id which is given to him to open his locker with the help of a keypad.
Immediately the locker will be opened. After the work has been completed if a
switch is pressed the locker will be closed again. If an unauthorized person
tries to scan his image then an indication will be given by a buzzer which is
interfaced to the controller. If an authorized person forgets his id he will be
given 3 chances to re-enter the id.
This project uses regulated 5V, 500mA
power supply. 7805 three terminal voltage regulator is used for voltage
regulation. Bridge type full wave rectifier is used to rectify the ac out put
of secondary of 230/12V step down transformer.

Advantages:
- Sophisticated security
- No manual errors
- No false intrusion
- Need not to carry ant card
- Others cannot steel the user’s entry key
Scopes for
Advancements:
- GSM modem can be connected to this unit to communicate to security department, in case of unauthorized entry trials.
Applications
- Industries are using finger print modems for access control, Stores, attendance recording, and machine operation authentication.
- Banks and ATM
- Voter Identification and electoral enrollment
- Personal Computers
- Automotives and high end cars
