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.
Registering the attendances of students have became 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 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 students will be stored in the module with a unique id.
To register their attendance the students have to scan their image
which is then verified with the image present in fingerprint module and
their attendance is registered for that day.
This scanner is interfaced to 8051 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 list of absentees for that day.
