Finger Print Based Online Voting System Using Microcontroller

This paper proposes a new method of an online voting system using Steganography. Steganography merge Cover image (Template image) and Secret key, this produces a Stego image which is similar to Template image. To cast a vote, a voter logs in to the system by scanning the fingerprint. If authenticated by the fingerprint match then the voter is allowed to log in to the voting system by entering pin number and secret key. The system will create the stego image by embedding the secret key and pin number. Now this stego image will be sent securely to the server for voter authentication. At the server side, the secret key and pin number from database stego image and voter’s stego image is extracted and compared to perform the voter authentication function. Once authentication is complete, the voter will be allowed to vote. In this work 8051 Microcontroller is used as the controller unit. This system includes RF module, GSM. Every user should have unique code for RF module. This provides additional security for voting. GSM Modem is connected to a computer.GSM send counted votes to Election Controller with particular time to avoid manual counting, this reducing the counting time. This system greatly reduces the risks as the hackers have to find the secret key, fingerprint image, which makes the election procedure to be secure against a variety of fraudulent behaviours.
