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 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 user’s 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 and displays on the LCD. If the scanned image is matched with the stored
image memory then it compares and displays authorized message. If the data is
not matched it displays unauthorized. For authorized persons, the door gets
opened and the person gets in after sometime the door gets closed. If it is an
unauthorized person it alerts the persons through a buzzer.
This scanner is interfaced to 89S52
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 doesn’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 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 remember any password
- 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
