Biometric finger print based voting machine using ATmega328P microcontroller

Abstract In this paper, an approach of designing of a finger print based voting system using fingerprint module and ATmega328P is presented. First we are having one database which will store all the valid information of user such as Aadhar Card Number, finger print (linked with Aadhar Card) & Voter card number. Now during the Voting time, using the individual login credentials the user will fill all his/her details in registration form. This registration details will be verified by the details feed earlier in database, if all the details of the voter matches with the server feed information the user can move for voting process otherwise it will end the process. After reaching at voting process, user will first verify his/her fingerprint pattern and then he can vote. Here the user will be recognized by his/her unique fingerprint pattern. Since the finger print pattern is not same for any two persons. So, the voter can’t vote twice or more. This system also give permission to admin to get the result just after the election completes. And allow admin to change/delete the data after completing the election result.
