Fingerprint based Patient Information System:

Fingerprinting is the process of identification based on the impressions made by the  fingers.  The impressions
consist of patterns  formed by ridges that cover the skin of the  fingertips.  Fingerprints provide one of the most
reliable methods of  identification.  No person’s fingerprint is identical to any other human being. In most cases,
fingerprints  remain the same throughout any person’s lifetime. Ridges on the person’s fingerprints only change
as a result of surgery, disease, or an accident.

In our project we are using a scanner. It will scan the finger print of patient. Then this image is given to personal
computer  using  USB  port  where  patient’s  database is maintained. In this database contains the information
regarding the patient like, the patients previous problem, medicine, checking data, current patient condition, the
patient's  medicine. If  any  emergency occurs, PC passes the information to the microcontroller via the parallel
port  which  alarms  the buzzer  and  displays  in LCD display.  Here  front  end  of project is in visual basic,our
microcontroller programming is done in embedded C.

Biometric Door Access Control and Attendance Maintenance System:

With the advent in technology, the existing systems are developed to have in built intelligence. This is of greater
importance in places where human identity is required. The manual authentication and human intervention of the
present  systems  has  been  replaced  by  digital means. Of all the digital systems, the Embedded Technology
predominates as it overcomes the drawbacks of all the existing mechanical and electronic systems.

Our  project “Involuntary Biometric Door Access Control and Attendance Maintenance System”  will manage  the
security  system  of any office, industry and any secured place. Here we are using scanner for taking finger  print
and  the  scanner  is  connected  with  the  PC.  Fingerprint is checked by the PC to find there is any match, if it
matches with already saved fingerprints.PC will send some signal to serial port that's received by microcontroller
which will drive the motor to open the door, at the same time maintaining the attendance for future reference.

Biometric Sensors based Digital Voting System:

With the advent in technology, the existing systems are developed to have in built intelligence. This is of greater
importance in places where human identity is required. The manual authentication and human intervention of the
present  systems  has  been  replaced  by  digital means. Of all the digital systems, the Embedded Technology
predominates as it overcomes the drawbacks of all the existing mechanical and electronic systems.

Our  project  “ Bio Metric Recognition System  Based  Digital Voting System ”  is  very  useful  to  recognize  the
authenticated person.In personal computer citizen finger print,name and other data’s are maintained.In our project
finger print scanner  is  connected  to PC via USB port. Person finger print is captured and given to PC where new
finger print is compared with  authenticated  finger prints, if it matches it will give some binary value to parallel port
that  is  given to microcontroller.Controller accepts the data and displays the authentication and will also be ready
to accept  the  voting. If  any unauthenticated person comes for voting, PC will give some other binary value to the
controller, which displays unauthentication of the person along with the alarm.
