ABSTRACT—Unified Modeling language (UML) is one of the important modeling languages used for the visual
representation of the research problem. UML uses object oriented design concepts and it is independent of specific
programming language. Unified Modeling Language is a popular technique for documenting and modeling system.
In the present paper, UML model is designed for the Election management system. We did a deep analysis and
design UML diagrams for election management system. We designed class, use case, sequence diagram etc using
rational software Architect tool.
Keywords—UML, EVM, Class Diagram & Sequence Diagram.
I.INTRODUCTION
A UML tool or UML modeling tool [1] is a
software application that supports some or all of the
notation and semantics associated with the Unified
Modeling Language (UML), which is the industry
standard general purpose modeling language for
software engineering.
UML tool is used broadly here to include application
programs which are not exclusively focused on UML,
but which support some functions of the Unified
Modeling Language, either as an add-on, as a
component or as a part of their overall functionality.
1.1Kinds of Functionality
UML tools support the following kinds of
functionality:
a) Diagramming
Diagramming in this context means creating and
editing UML diagrams; that is diagrams that follow
the graphical notation of the Unified Modeling
Language.
b) Round-trip engineering
Round-trip engineering refers to the ability of a UML
tool to perform code generation from models, and
model generation from code (a.k.a., reverse
engineering), while keeping both the model and the
code semantically consistent with each other.
c) Code generation
Code generation in this context means, that the user
creates UML diagrams, which have some connoted
model data, and the UML tool derives from the
diagrams parts or all of the source code for the
software system. In some tools, the user can provide a
skeleton of the program source code, in the form of a
source code template where predefined tokens are
then replaced with program source code parts during
the code generation process.
d) Reverse engineering
Reverse engineering in this context means, that the
UML tool reads program source code as input and
derives model data and corresponding graphical
UML diagrams from it.
II. PRODUCT FUNCTION
User: Operator
There is only one Operator for the system which
feeds all the details about the Constituencies, Polling
Booths and EVM machines. The particular Operator
has its own Id and Password by which he can log into
the system and feed all the information per
requirement. For more accuracy there is a profile
provided to the operator so that he can also feed up
his own details. Also he can update his profile as
required.
User: Administrator
There is an Administrator who has all access
permissions and he is only responsible for creating
another user which will be having access to the
system. Administrator can also update his/other
profiles. Administrator can also delete a user.

User: Assistant Returning Officer
Assistant Returning officer is the person who assists
the Returning Officer and gives relief to the
Returning Officer from his work, just by dividing his
work division wise. He is also provided an Id and
Password so that he can make use of the system.
User: Returning Officer
Returning Officer also known as District Election
Officer mainly collector is the supervisor of the
election at the district level. He is the man who
assigns duties to the Polling officer according to their
pay scale and designation. He generates first, second
training letter for the Polling Officers including
Presiding officer, first Polling officer, second Polling
officer, third Polling officer. He performs the
Randomization of the Polling officer and also for the
EVM machines. An lower level officer can also be
released from his duty having genuine reason by the
Returning officer. For this project a Returning Officer
will be provided an Id and password (given by
administrator) to fulfill the functional requirement.
III. USE-CASE MODEL SURVEY
Use-case for Administrator: To create, delete,
update and maintenance of users.
User: Observer
In an election to see how the process of election is
going on an observer is appointed. An observer can
have more than one polling booth in his observation.
The main duty of an observer is to check everything
if he finds any mistake than he can inform to higher
authorities and then higher authorities can take
action. So in short we can say he has the power to
dismiss any of the officers at any polling booth.
Related to this project an observer has to check the
randomization of the polling officer done by
Returning officer. Administrator provides an Id and a
password to the observer to use the system.
User: Chief Election Commissioner
Chief Election Commissioner is elected by president
of india and along with him two election
commissioner are also appointed. Now at state level
chief electoral officer is appointed by Chief election
commissioner. After that C.E.O of state will appoint
R.O, A.R.O. , Observer etc. In this project C.E.C. is
provided an Id and a Password by the administrator to
use the system.

Use-case for Observer: it is appointed by C.E.C to
observe election that will randomize polling officers
Use-case for CEC: Head at centre
Use-case for R.O. and A.R.O.: RO and ARO checks
details, Assign post to polling officer according to
pay scale, Randomise duties, Randomise E.V.M. The
details about the polling officers whom the duties will
be given to conduct the efficient voting at the polling
booths. The Polling officers will be assigned duties
according to their designation and pay scale. The
polling officers will be Presiding Officer, 1 st Polling
Officer, 2nd Polling Officer and 3rd Polling Officer
respectively according to their ranks.

VII. IMPLEMENTATION ISSUES
1. Taking Requirements seriously: voting systems
are like all other systems. In order to implement a
successful system it is not only required to
understand the requirements correctly; it is also
necessary to respect them. In order to have success
with voting technology, it has to be tailored to meet
the requirements of election organizers and voters
rather than those of the vendors.
2. Computer Knowledge: every user must aware
about computer that how to operate it.
3. Deployment of a Private Key: Having the voters
generate one-time key pairs on their web browsers
and having certificates on those keys issued on-line.
In practice we work with the model that each voter
receives a cryptic user identity and a one-time
password, based on which the certificate is issued online. The user identity and the password must be
received through two different channels in order to
provide a decent level of security. We consider two
physical letters with some days in between as the
most realistic option
4. Protection against Hackers: We will understand
the word hacker in a broader sense so that it includes
system administrators, who can completely
legitimately 21 observe and control computers of
voters remotely, as well as hackers breaking in
without permission. If a hacker observes the voting
process, he will not gain any information about the
candidate chosen, even if he has full control of the
computer of the voter. Furthermore, if he tampers
with the vote, the outcome will be uniformly
distributed on all candidates.
VIII. CONCLUSION
From the above, it is concluded that the UML Class
model
is a powerful model used to depict the software
development problems. In this paper, we have
presented a conceptual approach, based on the UML,
for the modeling of election management processes.
By UML we represents the system with structural
and behavioural language models and those designing
modeling include the architectural mechanical and
detailed design .Object oriented methodologies have
employed in the construction of the real time system.

5. Long Term Privacy: The universal variability
means that anybody can connect each voter to the
cipher text. Security is based on the assumption that it
is infeasible to decrypt the cipher text and see what
the voter has voted. In order to protect the privacy of
the voter, not just at the time of the election but also
several years into the future, the keys used for the
cryptosystem must be large.
