Geochronos File Sharing Application Using CloudIJERA Editor
Accessing, running and sharing applications and data at present face many challenges. Cloud Computing and Social Networking technologies have the potential to simplify or eliminate many of these challenges. Social Networking technologies provide a means for easily sharing applications and data. Now a day’s people want to be connected 24x7 to the world around them. Networking and Communication have come together to make the world a small place to live in. People want to be in constant touch with their subordinates where ever they are and avail emergency services whenever needed. In this paper we present an on-line/on-demand interactive application service (Software as a Service). The service is built on a cloud computing basement that provisions virtualized application servers based on user demand. An open source social networking platform is leveraged to establish a portal front-end that enables applications and results to be easily shared between users. In the proposed system users can access the documents uploaded into the cloud by others and provide any data they have in hand to other users through the same cloud. This also allows the users to have an interactive session through the chat screens present in the cloud. The paper also highlights some major security issues existing in current cloud computing environment.
Web engineering focuses on the methodologies, techniques, and tools that are the foundation of Web application development and which support their design, development, evolution, and evaluation.

Like a Server Operating System (SOS) and a Cloud Operating System (COS) are responsible for computing resources. In a server the OS is responsible for managing the various hardware resources inside a server’s frame. A Web Operating System serves the same purpose like traditional server does. Instead of managing a single machine’s resources, a cloud Operating System is responsible for managing the cloud infrastructure. But unlike a traditional Operating System, a Web Operating System has to do everything at scale. In present paper we would discuss and study Web OS.

Abstract—Cloud computing model is used for enabling
convenient as well as on-demand network access to a shared pool
of computing resources that can be quickly allocated and deployed
with minimum efforts.
Online compilers using cloud computing eliminates the
problem of portability and storage space. This model provides the
programmer the capability of using different compilers and to
pick up the fastest and most convenient tool to compile the code
and debug the program. Moreover, the web-based application
being proposed can be used remotely through any network
connection and it provides platform independence. The
error/output of the code is store in the most convenient and
efficient way. Also, the manual process of installing the compiler
on each computer is avoided. By using this application we can also
conduct online practical examination.

I. INTRODUCTION
We are proposing a model for a cloud-based education
system to provide a platform for students, teachers and the
university which can aid in the learning process. Our system
consists of many modules such as online compilers, live
practical examinations and automated attendance-taking and
online study materials. The student just needs to login to his/her
account and can make use of the available facilities. Similarly,
provisions are made for faculty access. Our Computer Assisted
Education model is based on cloud computing and its different
services.
At the core of our system the following modules are present:
a) Online compilers for compiling programming
languages such as C, C++ and Java etc.
b) A live practical examination module which can aid in
real-time conducting of a university practical
examination.
c) An automated attendance-taking system with which
the faculty member can take attendance with the help
of a user friendly app.
d) Important notice uploading feature for the university
as well as the institute.
e) Study materials such as presentations, PDF files and
links to educational resources.
The cloud based system being proposed can be deployed
in colleges and can even be scaled up to the university level.
The system can efficiently manage various aspects of the
education process. It is centralized and thus all the students of
a college or a university can efficiently make use of a single
system for all purposes.
The system being proposed will make use of the cloud
infrastructure which itself will provide the distributed computer
system features. The implementation of the infrastructure is
abstracted from our system and we only have to concern
ourselves with how to deploy our application on the cloud.
The proposed system overcomes the major drawbacks in the
traditional manual method of the education process. Moreover,
as technology improves day by day, we must advance our
learning methodologies along with it. The system helps in
achieving these goals. Efficient maintenance and management
can be achieved using the proposed system.
II. RELATED WORK
A. Cloud Computing
Cloud computing is evolution of utility and grid
computing. Utility computing delivers the renting of on
demand-computer resources. While grid computing provides a
high-performance system by combining multiple computing
resources, distributed in various locations over the net, to
compute very big computational problems. IT technologies
such as Service Oriented Architecture, Virtualization models
are also used in key concepts of cloud computing. It delivers
IT resources, such as networks, servers, storage, software,
applications, and documents. Cloud computing can provide
various additional features such as flexibility, scalability,
accessibility, high performance, reduces operating costs and
implements green environment. It allows users to access any
resources by paying for what they need, rather that purchasing
the resources directly.
The National Institute of Standards and Technology
(NIST), has defined five essential characteristics, three service
models, and four deployment models in its definition of cloud
computing. The five essential characteristics consist of on-
demand self-service, rapid elasticity, measured service, wide
network access, and resource pooling. The four deployment
models are public, hybrid, community, and private cloud.
Finally, the three service models include Infrastructure as a
Service (IaaS), Platform as Service (PaaS), and Software as a
Service (SaaS).
B. Online Compiler
Compiler runs a program and converts them from text to
executable format. To install compiler manually on each
system requires lot of physical work and space. As soon as the
program is compiled it becomes platform dependent.

using Cloud Computing” [1]: This system provides two layer
in its architecture, lower layer and upper layer consisting of
clients and servers respectively. The system is platform
dependent and works on windows as well as linux operating
system. It reduces information overhead for the end-user, also
has greater flexibility, reduced total cost of ownership and on-
demand services with other advantages. The project provides
online compilers for institution or organization, also provides
database to store codes. It uses OCC (Online Centralized
Compiler) technology.

: Three tier
architecture of cloud computing model is used to build this
system. The architecture consists of data layer, business layer
and application layer. Data layer contains account information
of users. Business layer acts as decision making, while
Application layer acts as interface. A feature called Code
Document Object Model (CodeDom) is provided by .NET
framework. This system is platform dependent and works on
windows operating system. It uses Code-Dom technology.
III. ONLINE COMPILER
An online compiler is a compiler which is deployed on the
Internet. It can be deployed using a web-based application. A
compiler is a computer program (or a set of programs) that
transforms source code written in a programming language (the
source language) into another computer language (the target
language), with the latter often having a binary form known as
object code.
Organizing files is a major issue in software development.
Students have to compile and run many programs every day and
they need to store these files on flash drives. Students often lose
their data when they misplace their flash drives. This is why we
are proposing a cloud based solution. Moreover, programs can
be compiled from anywhere with just a computer and an
internet connection. Students need to focus only on the coding
process and not on unnecessary tasks like installing of software
like compilers. Auto-save capabilities can create a backup of
the code which is useful in case the internet connection fails.
Programming can be done using any device and the output can
be viewed on the device as we are using a web browser to
display it.
IV. PROPOSED SYSTEM
A. Proposed System
The proposed system is a web-based application that
consists of modules such as online compilers (which are
deployed on the cloud), department-wise notice module, an
attendance taking application, practical examinations module.
A web page will provide a user friendly UI for the student.
Each student will have their own account and will be able to
access their files through a user id-password combination. Once
the user is authenticated, he will be able to access the modules
discussed above. A text editor on the webpage will be used to
type the code that needs to be executed. Once the user finishes
typing the code, he can click on the submit button which will
run a PHP script on a web hosting server that sends a file
consisting of the typed code to the cloud. The online compilers
are deployed on the cloud and they compile the code and store
the output in a file. The output file is retrieved by the PHP script
running on the web hosting server and is displayed on the
webpage.
The practical examination module is a novel technique
which will allow colleges to conduct practical examinations
online. The advantage of using this module is that it will be
harder for students to cheat during the examinations. Also,
problem statements will be assigned to students such that two
adjacent students will not get the same problem statement.
Fig. 1. Proposed System
To design the web-based application, a webpage will be
created containing links to different modules. PHP will be used
to link cloud services to the web-based application. Educational
institutes and any individual can access the web-based
application through their personal accounts. Privileges will be
assigned on the basis of the designation of the individual.
1) Product perspective:
a) User account: The system allows the user to create
their accounts in the system. Some of the user
accounts have special privileges such as teacher or
institution level privileges.
b) Number of users being supported by the system: The
system is able to support a large number of online
users at a time.
c) User Interfaces
d) Web-based UI, Android application UI
e) Software interfaces
2) Memory Constraints:
Cloud based model does not have any memory constraints,
if there is more traffic we have to pay the cloud service provider
more for server space.
B. Modules
The major inputs to the system would be in the form of text
and through clicking on buttons in the GUI. Output of the
system is compiled code, attendance records.

3. The system provides the following modules:
1) Automated Attendance Application:
Taking attendance is a manual and tedious task for teachers
in colleges as they have to carry separate books to maintain
attendance records. Moreover, many errors are introduced in
the attendance data.
An Android application would be installed on the teachers’
smartphone. This Android application provides features such as
single-click attendance, a simple user interface and cloud-
syncing, the disadvantages of the manual method can be
overcome. Statistical information in the form of reports can be
produced using the collected data such as average attendance of
a student for the past few months.
A backup of the attendance can be stored on the cloud to
ensure reliability of the data. Also, the attendance details can
be viewed on a smartphone or any other device. We can add
more features to this application in the feature, such as SMS
notifications- which will be sent to a student to warn him/her
that his attendance is below the minimum.
2) Notice Uploading:
The online portal will allow uploading of important notices
and instead of all the notices being centralized, each department
will have its’ own department-specific notices. Students can
stay up-to-date with the latest updates from the university.
This module allows a student from the Computer
Engineering department, for example, to view notices regarding
the Computer Engineering department. The student does not
need to search for his particular departments’ notices.
Teachers will have special privileges which can be used
to upload the notices. Students will have restricted access so
that they can only download the notices and not modify them.
Currently, the university does not have a department-specific
notice system. This makes it difficult to find his/her
departments’ notices. All these disadvantages can be avoided
by incorporating this module into the system.
3) Learning/Study Material:
The learning material module would include: Subject-wise
PPTs, textbooks and reference books in a PDF format, video
tutorials, code samples, practice tests.
Students have to run helter-skelter to obtain study material.
Sometimes, just a few days before the exam. This module will
contain all the necessary study material which can be
downloaded by the student. Faculty members may even upload
a PPT of their lectures. This greatly helps the student in the
learning process because even if he/she missed a few points,
he/she can obtain a complete transcript of the lecture.
4) Online Practical Examination:
This module is an important feature of the system which
enables colleges to conduct cheat-proof practical examinations
online. Since a webpage is being used for conducting the
practical examination, any event that happens on that particular
page can be detected- such as minimizing, closing, or switching
tabs. Also, insertion of external flash drives can also be
detected. All attempts to cheat are logged and are submitted to
the invigilator.
Traditionally, the external examiner needs to visit each
students’ computer to check their code. As everything is
centralized, the external examiner just needs to login to his/her
private account and check the code. This saves both time and
energy and improves efficiency in the conducting of practical
examinations.
This module uses online compilers to compile code. The
interface provides text editor, various GUI buttons, output
window, timer etc. Features of online practical examination
module:
a) Allotment of Problem Statement: Problem statements
are alloted automatically .Virtual chart of Lab is generated
through ip-address of systems present in lab. This chart is then
used to allot problem statement in such a way that no two
consecutive systems are allotted same problem.
b) External drive detection: Logs are checked
continuously to detect any connected external flash drive. If any
drive is detected, the system will inform invigilator and also
will not allow that student to continue exam untill invigilator
allows.
c) Switching Tabs: This problem arises with online
compiler, as students can use internet to cheat in examination.
This module detects switching of tabs by constantly monitoring
logs generated by respective browser.
d) Timer: With this feature, a fixed time can be provided
automatically for examination.
e) Storage: Programs executed by students are stored
automatically on cloud and can be accessed by invigilator and
external examiner.
C. User Profiles
1) Students:
Lowest level of privileges and permissions for student
accounts. Students can compile their code, view notices,
download study material and check their attendance through the
web portal.
2) Faculty Members:
Higher level of privileges and permission that students.
Faculty members can generate reports of monthly attendance
and can upload important study material. Faculty members can
start a practical examination session through which students
can be tested.
D. Functioning
The initial state is for logging in, here the user is
unauthenticated and must enter his/her username and password
to get authenticated. New users can register by providing details
like email id, mobile number, name, roll-no etc.
Another state is the examination state. Here, students
implement programs in an editor, the code is compiled and
executed and the output can be viewed. In this state, the cheat-
proof security measures are implemented to ensure students
cannot copy. Students can also save data like programs to their
accounts to view later.

uploaded by faculty members in an organized manner
CONCLUSION
In this paper, a cloud based education system formed by
integration of various modules such as online compilers, an
automated attendance application, notice uploading and
practical examination modules is proposed.
Compilers do not need to be installed on individual
computers and students’ only need to login to their accounts to
access the compilers.
This system saves both time and effort of colleges, faculty
members and students by managing all the aspects of the
education process on the cloud.
FUTURE SCOPE
The proposed system can be extended to support additional
features such as:
The Android attendance application can store all of the data
on the cloud, so that the data does not need to be stored on the
teachers’ device. The Android attendance application can also
have a feature to send an SMS to a student with his/her
attendance for the month, eliminating the need for students to
keep checking the notice board for attendance notices. Students
can send an SMS to the system and their respective attendance
is replied back in the form of an SMS.
The online compiler module can be extended for more
programming languages such as Python, Ruby etc. Colleges
host many events annually and other college students are
sometimes allowed to participate in such events. Traditionally,
students from one college have to campaign at other colleges.
Using the online portal, colleges can post events publicly and
can access a larger audience.
The cloud based system can be scaled up for use by many
universities and can prove to be a viable alternative to the
traditional method of education. Education must evolve with
the available technology, this system helps to achieve this goal.
