Online voting

1. INTRODUCTION
1.1 SYNOPSIS
The project titled “Online Voting System” is designed using ASP.NET as front end and SQL
SERVER as back end.
This project deals with voting in online. We can implement this software in a campus,
society or the State . This project mainly contains three levels, users Administrator, super wiser
of a booth and members. The Voters are thoroughly scrutinized and high end security system is
implemented , for maintaining a transparent and smooth Vote casing procedure.
Modules of the Project
1. Administrator
a. Creating Candidate
b. Confirm Members
c. Count Vote
d. Result
2. Users
a. Member registration
b. View Candidates
c. Voting

PROJECT DESCRIPTION
MODULE DESIGN
The proposed system consists of two modules,
• Administrator Module
• User Module
USER (VOTER) MODULE
User interface consists of a login name and unique password using which he/she can login into
the Online Voting System. This will be supplied by the administrator to the user. Once the user has
logged in, he has the privilege to view the names of the candidates listed by the administrator, view the
results after the termination date of the election. The user module constitutes only one sub module:
Authentication & Voting
• Each voter is provided with unique username and password manually by the administrator. The
voter uses the username and password for login and exercise the fundamental right of voting. if
incorrect username and password entered, the access to is denied to the user. And also voter is
allowed to vote only once. This is the security feature provided against external access of the
system.
• After login the voter enters the voter home page ,which provides the links :
Candidate List
This facilitates the voter to view the candidate names, the constituency name, their symbol
and their party name.

Vote
This provides the voter with a list of candidate with in his/her constituency along with
selection option (radio button) to select the preferred candidate from the list. If the voting date is
before termination date, the vote goes valid else goes invalid.
View Results
This provides graphical and user friendly representation of the votes obtained by each
candidate. It includes the percentage of the votes obtained by each candidate. But the result can be
viewed only after the termination date of the election.
Logout
This provides an option for the voter to quit the session ,while in the voter home page.
ADMINISTRATOR MOD
Administrator interface consists of a login name and unique password using which admin
can login into the Online Voting System. Administrator has the main control of the system. By logging
into the page it can perform the following tasks.
Add Candidate
Here the admin can add the list of candidates in the election. It includes candidates name,
address.gender,party, party symbol etc. The candidates will be added to the list only after completing
the procedures.
Add Voter
Here the voters can be added to the database. The voters have also the privilege to check the voters
list from the homepage. The voters details includes name, address, gender, age, constituency, image etc.

Add Election
Here the election to be conducted is selected. To add an election the constituency should be selected
and termination date of election should be specified.
Add Constituency
The constituency that is going to conduct election should be selected.
Voters List
Here we can view the voters list. Each constituency will be having separate voters list.
Candidate List
The list of candidates participating in the election can be seen. It includes the candidates name, party
name and party symbol.
The sub-modules of administrator are:
 Voting Structure,
 Voters Registration
 Candidate Registration
 Counting & Categorization of Results
Voting Structure
Here the eligible voters who are permitted to login to the system can utilize the right to vote.
Each voter can register a single vote to a candidate’s favour in his/her constituency. The security
measures taken within the system prevents them from exercising their votes again i.e. the second vote
by the same user goes invalid. The starting and ending dates of the election are specified by the
administrator. The user must have an identity card and he must be in voters list.

Voters Registration
The registration procedure of all the eligible voters .This registration process is done by the
administrator. According to voters database each voter is provided with a unique identification codes
which includes username and password.
The details of the voters include username, password, name, address, gender, constituency,
image etc.With the voter registration, thus producing the voter list with the given information of the
voters. The voter list can be viewed by anyone accessing the webpage. The admin can view the voter list
with in his homepage.
Candidate Registration
The registration of the candidates in each constituency is done by the administrator. The details
of the candidate includes name, address, gender ,his/her constituency, party and image. With the
candidate registration, thus producing the candidate list with the given information of the candidates.
The candidate list can be viewed by admin and the vote within their respective homepages. According to
candidates database (manual) each details of the candidates are stored in database controlled by the
admin including candidates details.
Counting & Categorization of Results
When the voter votes, the number of votes obtained by the selected candidate is incremented
by 1.The result is published only after the voting process is over. It is accessible from the next day after
the termination date. Here we depict the result in the graphical representation according to the
percentage of vote obtained by the candidate. Result can be viewed by everyone who visits into the site
without any authentication problem. A link to view the result is kept in the index page and both admin
and voter can view the result in their respective homepages. When the user clicks the “RESULT” link,
before the termination date of theelection, “Result not Published yet” Message will be displayed. The
result comes with their party symbol on the top of the graph representing the percentage of vote
obtained by each candidate.

CONCLUSION
In Performing Analysis, Design, Coding and Implementation we had made success in
matching the system objectives with the goals of the organization. The newly developed system
consumes less processing time and productivity is increased. Since the Navigation is
maintained throughout the system they are much user-friendlier. Even a Novice user can use
this System.
