FINGERPRINT BASED ELECTRONIC VOTING SYSTEM
According to 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. To provide perfect security and to make our work easier, 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 the fingerprints of up to 100 users. This module can operate in 2 modes i.e., 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.
The main aim of this project is to avoid rigging completely. Electronic voting systems have come into picture to prevent rigging up to the maximum extent. But even there may be some malfunctions during elections. Thus, fingerprint based electronic voting system has been designed. When a person wants to register himself in the voter list, he has to provide his complete details along with his fingerprint image. Thus, when the same person comes to poll his vote during the elections, he needs to give his fingerprint image before polling his vote. Thus, the system scans his fingerprint image, compares the image with the already stored image. If both the images are matched, the person can enter into the room to poll his vote. The door will be opened when the switch is pressed by the polling officer. If not, the system simply alerts the buzzer not allowing the voter to poll his vote. LCD is used to display the related messages. There is three buttons for three parties. We can poll votes through respective switches.
Here we use 8051 as a microcontroller with 5v DC Power supply. Serial (UART) protocol is primary concern here. The heart of this project is Bio metric module which works on serial (UART) protocol. 16X2 LCD display is connected to microcontroller through digital I/O pins.
