Biometrics is the term given to the use of biological traits or behavioral characteristics to identify an individual. The traits may be fingerprints, hand geometry, facial geometry, retina patterns, voice recognition, and handwriting recognition. In this paper we have used thumb impression for the purpose of voter identification or authentication. As the thumb impression of every individual is unique, it helps in maximizing the accuracy. A database is created containing the thumb impressions of all the voters in the constituency. Illegal votes and repetition of votes is checked for in this system. Hence if this system is employed the elections would be fair and free from rigging. Thanks to this system that conducting elections would no longer be a tedious and expensive job.


The design of the system consists of the following important parameters. 1. Scanning- using DSP Processor
2. Searching- based on the principle of GOOGLE SEARCH
3. Networking- all the election booths are connected in a network 4. Data transfer– using telephone lines..

The only pre-requisite for the use of this finger print scanner is a personal identification card. We hope that this system proves to be efficient and enables the people to be smarter in choosing their leaders.


The main aim in designing this product is to provide the concept of the personal identity for each individual. This is extended to a special case of electronic voting machine concept. The summary of the design can be briefly explained diagrammatically as follows.

Fig-1.1 : Block Diagram of Design
As initially at time of distributing voting cards. At the time of voting, the option of the voter is taken along with the finger print. The finger print taken by the scanner is sent to the DSP chip through an in-built A/D converter. The processed image is transferred to hard disk with biasing of SDRAM. The option entered by the voter is transferred to chip through DEMUX and is stored in the memory. If the transferred image is matched with any of the records in the data base, then the interrupt is given by the HARD DISK to DSP chip. Then the option is considered in the count. After the acquisition of the count this is transmitted to the HOST computer or central server using telephone lines. As the count of each party is transmitted to the HOST from all the VOTING MACHINES present in the constituency, the HOST will add parallel count of particular party and makes the final count of each party in ascending order. The final count is transferred to the main HOST (head quarters) using either telephone lines or radio waves.

The detailed description of each and every internal unit in the VOTING SYSTEM is given below. It can be divided in to the following main categories.


The finger print scanner consists of the following parts:

1. FINGER PRINT SENSOR: This is used to scan the thumb impression. The data obtained from this is analog in nature. This is transferred to the A/D converter for further processing. 2. A/D CONVERTER: This is used to convert the analog data from the SENSOR into the digital data and transfer it to...
