Feasibility StudyMotivation:

The present Voting system, i.e. the system using EVMs (electronic Voting machines) has

successfully replaced the old system that used paper ballets. Now, as the e-world is

spreading like a wildfire, time has come to apply the online concept to the present Voting

System. This would not only increase the percentage of votes cast, but will also bring down

the cost of conducting elections. Also, people who do not live in their hometowns will be able

to cast votes, thus further increasing the percentage of votes cast and giving us better or

more accurate and precise results.

Input Assumptions:

All the voters have their Unique ID. All voters are literate. All voters have access to the internet. Voters will need to register using their unique ID before they can vote. All voters will have a secret password, which will be generated at the time of

registration.

Problem Definition:

The conventional voting system using EVMs is easier and safer than ballets, but still itscostlier as Voting centers are formed and people assigned to overlook the entire process

are given TAs and DAs out of the government reservoir.

Not all voters can cast vote as many of them live in other towns and cities. People have to travel long distances to cast their votes. The additional cost of counting of votes. The wait and delay in the results. The cost of security provided for the EVMs.

Objective:

The online Voting system is a user Friendly online software, where users can register and log

in to cast their Votes without the hassle of travelling to a voting centre. The main objective is

to maintain a record of all the voters and conduct online polls during election period.

7/30/2019 Ovs Final Edit 23 04 12 (1)

5/44

ONVS 5

Maintain records of all the citizens. Keep records of the eligible vote bank of a particular election being conducted at a given

time.

Keep a record of the votes cast for all the candidates.

Keep a record of all the votes cast. Give result as soon as the end of elections. Calculate the percentage of votes cast. An educational tour will be given to all the users at the time of registration. User manuals will be provided several days before elections. One person can vote only once, though they can log in again to see who they cast vote

for.

The administrators input all the information about the Candidates before polling opensand can change it after one poll for reuse of the software.

The administrators have access to all the data input by voters. At the end of elections, the administrators can announce the winners right away. Voters can change their password after they log in.

1.6 Overview:

The rest of the SRS is organized as follows:

Section 2 gives an overall description of the sw. It determines the level of proficiency whichis expected from user, some general constraints while making this sw and making some

assumption and dependencies.

Section 3 gives special requirement which the sw is expected to deliver. Functional

requirements and some design constraints are also given.

Section 4 gives some possible future extensions of the system.

2. Overall Description2.1 Product Perspective:

The online National Voting system is a self contained system that manages all the on goings

of national or regional elections. From maintaining database to conducting elections in a

fruitful manner, and then giving results right away. The election commission will appoint the

authorized body to view, maintain and change the data regarding voters and candidates.

2.2 Product Functions:

3. Specific Requirements3.1Functional Requirements:

We describe the functional Requirements using Various Use cases:

3.1.1 Use Case Name: Voter RegistrationPrimary Actor: Voter

Pre-Requisite: Internet Connection, A genuine user with his unique ID for Registration.

Purpose: Registering the Voter to the Database

Main Scenario:

Voter enters the system homepage. He clicks the register now button. The system prompts the application form. He fills in the necessary information related with him in the application form. He sends the request for registration by using send button. If the information is correctly entered the system prints a successful message. Otherwise, it prints appropriate error message, redisplays the application form.

Alternative Scenario: Null

3.1.2 Use Case name: Update VotersPrimary Actor: Administration

Pre Requisite: Internet Connection, Updated Database

Purpose: To update the newly added Voters to Database and remove or edit information

about existing Voters.

Main Scenario:

Admin selects on Update Voters from menu and displays that page Admin click on Update Now button The system checks online voters with respect to upcoming elections voters list

7/30/2019 Ovs Final Edit 23 04 12 (1)

12/44

ONVS 12

If the voter exists in the list, the system updates the voter with respect to officialvoter information.

If the voter does not exist in the list, the system deletes that voter fromdatabase.

Alternative Scenario: Null

3.1.3 Use Case name: Log In/ Log OutPrimary Actor: User

Pre Requisite: Internet connection, UID and Password

4. Future ExtensionsEarlier EVM system of conducting elections took up a lot of time and resources. Using an

online system will strive to save both. Some more extensions are -Security: Sensitive data is protected from unwanted access by users. Appropriate

technology and implementing strict user access-criteria.

Provide good performance and ability to scale the server: The web application server

should provide good performance and ability to manage performer technique such as, faster

and easy access, reliability, etc.

Centralized database: CD will enable efficient management of data.

Safety and reliability: By incorporating a robust and proven RDBMS (SQL) into the

system, reliable, performance and integrity of data is ensured. There must be a power

backup for server system.

Voting without having to travel: Voters living outside India who have Indian citizenship

can also cast their vote.
