Voting System for Rigging-Free Governing


This kit voting system for rigging- free governing examines policies regarding the electronic approach and development toward electronic data storage and transmission. The person at the polling booth needs to scan his finger by placing the finger on the fingerprint reader. This fingerprint reader reads the details from the tag. This data is passed to the controlling unit for the verification. The controller reads the data from the reader and compares this data with the already stored information and the person is allowed to open the gate if the fingerprint matches the database. If not, a message is displayed on LCD and the person is not allowed. LCD is used to display the related messages.

In the kit voting system for rigging- free governing examines, the fingerprint scanner is there to scan the fingerprint and create a database. The microcontroller can ask it anytime to check the validity of the preset finger placed on it. If the user is valid then only the microcontroller allows the user to vote


Recently, during the state assembly elections in India, many parties and their representatives who were candidates for their respective local assembly raised their concern over the insecurity of EVMs across the state.

According to many accusations and media reports, the EVMs which were used during the state elections had been hacked and many voters had cast more than one vote due to which one party won easily by the majority.

This has led to a lot of research and development in the field of manufacturing secured machines. The machines need to have a simple and less power consuming backend technology as the EVMs have to be used all around the country. This means the machines should efficiently work even in areas with minimum power resources and should be simple as most of the target audience does not have exposure to electronics technology.

Keeping the issues in mind, we have developed an important and integral part of an electoral voting system which is the voter interface kit to demonstrate the overall voting process in a simplified manner.

Working Principle

Optical fingerprint recognition module fingerprint reader R305

This is an optical biometric fingerprint reader/sensor (R305) module with TTL UART interface for direct connections to a microcontroller UART. The user can store the fingerprint data in the module and can configure it in 1:1 or 1: N mode for identifying the person. This module can directly interface with any 3.3V or 5V microcontrollers, but a suitable level converter/serial adapter is required for interfacing with the serial port of a PC.

Working Principle

Fingerprint processing includes two parts, fingerprint enrollment and fingerprint matching (the matching can be 1:1 or 1: N). When enrolling, the user needs to enter the finger two times. The system will process the two-time finger images, generate a template of the finger based on processing results and store the template. When matching, the user enters the finger through optical sensor and system will generate a template of the finger and compare it with templates of the finger library.

For 1:1 matching, system will compare the live finger with specific template designated in the Module; for 1: N matching, or searching, the system will search the whole finger library for the matching finger. In both circumstances, the system will return the matching result, success or failure.

Brief Description

The system can be powered up with 12V 1A ac or dc power supply. The rectifying and filtering circuit is embedded in the system. The communication link between the fingerprint scanner and the microcontroller is the UART communication. The system can be upgraded and hence can be connected to the system where there can be a large database.
