The presentation summarized an online voting system project developed by 4 students. It included an introduction to the online voting technique and its key features like registration and login. It justified the project by explaining how it would reduce time and costs while increasing voter turnout. It presented the data flow diagrams, database tables, and screenshots of the system. It discussed testing measures and security issues addressed. Potential future enhancements were proposed like improved password changing and biometric authentication.

3. ABOUT ONLINE VOTING SYSTEM
•Online Voting System is an online voting technique
•Citizens above 18 years of age can vote online
ONLINE VOTING
TECHNIQUE
•Registration is mainly done by the system administrator
VOTING REGISTRATION
•If invalid/wrong details are submitted, then the citizen
will not be registered to the system.
REGISTRATION
VALIDATION
•After registration, the voter is assigned a secret Login
ID and password to log into the system
LOGIN AND VOTE
CASTING
•During voting, the voters can enjoy online vote services
without going to vote center physically.
ENJOY SERVICES

4. PROJECT JUSTIFICATION
•OVS will reduce the time spend making long queues at
the polling stations during voting.
LESS EXPENSIVE AND
LESS TIME CONSUMING
•It enable the voters to vote from any part of the globe
as explained since this is an online application
available on the internet.
CAN VOTE FORM ANY
PART OF THE GOLOBE
•Less effort and less labor intensive, as the primary cost
and focus primary on creating, managing, and running
a secure web voting portal.
LESS EFFORT AND LESS
LABOUR INTENSIVE
•It will increase the number of voters as individuals will
find it easier and more convenient to vote, especially
those abroad.
INCREASED NUMBER
OF VOTERS
•Cases of vote miscounts shall also be solved since at
the backend of this system resides a well-developed
database
MISCOUNT OF VOTES
WILL BE SOLVED

5. PROJECT REQUIREMENTS
•Registration of the voter will be done by the ELECTION
AUTHORITY
VOTER REGISTRATION
•ELECTION AUTHORITY can change the information any
time if required.
ELECTION AUTHORITY
•Registration of the Voter depends upon the information
filled by the user manually to the ELECTION AUTHORITY
INFORMATION FILLED
BY THE VOTERS
•Voter is given a unique Login ID and PASSWORD.
UNIQUE ID AND
PASSWORD
•In the DATABASE information of every voter is stored.
•Database shows the information of every user
DATA STORAGE

6. DATA FLOW DIAGRAM (DFD)
•In this diagram, voters/ general public, candidates and
administrators functions are presented.
BLOCK DIAGRAM
•In this diagram, voters sign in with user and password;
and administrators access to the system is presented.
ACTIVITY DIAGRAM
•This DFD is represented the whole system as a single
process for the administrators/ admin users.
FIRST LEVEL DFD
(FOR ADMIN)
•This DFD is represented the whole system as a single
process for the voters.

22. TESTING AND SECURITY
•All the modules are being separately tested.
UNIT TESTING
•All the components are being separately tested.
a. Accessibility Testing b. Functional Testing
SYSTEM TESTING
•Not only outsider (such as voters and attackers) but
also insider (such as system developers and
administrators
SECURITY ISSUE:
INSIDER & OUTSIDER
•Inheritance of some objects in the source code are
unsuitable. These errors caused the voting system to
crash.
SECURITY ISSUE:
UNSTABLE SYSTEM
•We can design our system to transmit data without
network.
•limit voter to input particular data, so that we can
prevent the command injection.
SECURITY ISSUE
SOLUTIONS

23. FUTURE ENHANCEMENT
•Ensure more security concern during password
changing of voters/ public access.
PASSWORD
CHANGING
•Mandatory finger printing options for each users
could be introduced for more security concern.
FINGER PRINTING
•Cornea Detection options for each users should be
introduced for more security concern.
CORNEA DETECTION
The Online Voting System (OVS) platform can be made
more secure by using the following methods
