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.
Registering the attendances of students has become a hectic work as sometimes
their attendance may be registered or missed. To overcome this problem i.e. to
get the attendances registered perfectly 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. When coming to our application
the images of the citizens will be stored in the module with a unique id. To poll
their vote the citizens have to scan their image which is then verified with the
image present in fingerprint module and their vote will be updated.
This scanner is interfaced to AT89S52
microcontroller through max232 enabling serial communication. By using this
controller we will be controlling the scanning process. After the scanning has
been completed the result is stored in the microcontroller. By simply pressing
a switch we can get the details of the polling.
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.
