Definition:

SMS based voting machine is type of

machine on which user can dial the

specific number from any land line or

mobile phone to cast his vote. Once

the user is connected to the voting

machine he can enter his password &

choice of vote.

4

Current Market Solution :

• Electronic Voting Machines ("EVM") are being used

in Indian General and State Elections to implement

electronic voting since 2004 elections.

• An EVM consists of two units:

• Control Unit

• Balloting Unit

•  The Control Unit is with the Polling Officer and the

Balloting Unit is placed inside the voting

compartment.

 

5

Introduction:

• Cell phone based voting machine is capable of saving

considerable printing stationery and transport of

large volumes of electoral material.

• It is easy to transport, store, and maintain.

• It completely rules out the chance of invalid votes.

• The aim of our project is to design & develop a mobile

based voting machine.

• In this project user can dial the specific number from

any

land line or mobile phone to cast his vote.

6

Cont..

•Once the user is connected to the voting machine he

can

enter his password & choice of vote.

•User is allotted 15 seconds to enter his password &

choice.

•Note that time limit is set accordingly.

CIRCUIT OPERATION

•The format is”*user password & candidate

number”.

•The controller has been programmed in such a way

that no user can vote more than once.

•When the message is sent ,GSM modem interface

with Max 232 which receives the message and

transmits this message to controller.

•Then according to the programme candidates

votes are incremented and the final result appears

on the lcd.

Components:• Gsm modem

• ATmega32

• Max 232 IC.

• Voltage regulator 7805.

GSM Module

12

The MAX232 is an integrated circuit that converts signals from an RS-232 serial port to signals suitable for use in TTL compatible digital logic circuits. The MAX232 is a dual driver/receiver and typically converts the RX, TX, CTS and RTS signals. The drivers provide RS-232 voltage level outputs (approx. ± 7.5 V) from a single + 5 V supply via on-chip charge pumps and external capacitors

Feasibility:

• This project is very feasible as it reduces the required time for voting.

• Provided the base data for scrutiny work on the day after the poll, as per ECI guideline

• Preserving data for analysis and future use

• Reports are collected directly from the Polling Stations to the State Head quarter through SMS message avoiding any time delay and increasing the accuracy.

15

Application and Purpose.• The EVM system is a longtime-consuming process and

very much prone to errors.

• This situation continued till election scene was

completely changed by electronic voting machine..

Cell phone based voting machine is capable of

saving considerable printing stationery and

transport of large volumes of electoral material. • SMS based voting system can be used in remote areas

where manual voting system is difficult to implement.

• This system can be used in colleges , society and various other places for elections.

16

Further Enhancements & developments.

The system can be further modified to enhance its

utility. The enhancements are:

• Number of candidates could be increased .

•  It can be interfaced with printer to get the hard

copy of the result almost instantly from the

machine itself.

• It can also be interfaced with the personal

computer and result can be stored in the central

server.

17

Cont..

• Once the result is on the server it could be relayed

on the network to various offices of the election

conducting authority. Thus our project can make

results available at any corner of the world in a

matter of seconds.

ADVANTAGES OF GSM basedVOTING MACHINEVOTING MACHINEy

Democracy: All and only the authorisedvoters can vote,and each eligible voter can vote no more than once.Voters can also choose not tovote.y

Privacy: All votes remain secret while voting takes placeand each individual vote cannot be linked by anyindividual or authority to the voter who casts it.y

Accuracy: The voting result accurately reflects voters·choices. In thiscase, no vote can be altered, duplicatedor eliminated without being detected.y

Fairness: No partial result is available before the finalresult comes out.y

Verifiability:where any voter can check that her ownvote hasbeen considered in the tally.
