ABSTRACT

E-Attendance+ Management System deals with the maintenance of the students attendance details. It is generates

the attendance of the student on basis of presence in class. It is maintained on the daily basis of their attendance. The

staffs will be provided with the separate username & password to make the students status. The staffs handling the

particular subjects responsible to make the attendance for all students. Only if the student present on that particular

period, the attendance will be calculated. Concerned subject teacher will enter the attendance corresponding to the

subject and then automatically total attendance and percentage of attendance will be calculated by E-Attendance+

Management System. This system will also provide the facility to teachers to upload a file on the server, view a file

on the server and they can also download a file. Teacher can also upload some matter that is of great interest to

students like they can upload some research papers regarding current topics which they think students should go

through them to enhance their knowledge. Teacher can also generate the monthly report and a mail will be send to

those students who are having short attendance. This system also tries to bridge the gap between the teacher and the

student. It provides facility to teacher to interact with the students and gave them the required instructions so that

students can work according to that. Students can view their attendance in their corresponding subjects and came to

know that whether they are having short attendance or not. They can the documents, pdfs uploaded by the teachers

and can download them. Students can also interact with teacher and ask their doubts regarding syllabus , projects,

sessionals and exams.

INTRODUCTION

1.1OBJECTIVE:

E-Attendance+ Management System is a web applicationdeveloped for maintaining the attendance of the studenton the daily basis in the collage. Here the staffs, who are handling the subjects, will be responsible to mark the

attendance of the students. Each staff will have a separate username and password . An accurate report based on the

student attendance is generated . This system will also help in evaluating attendance eligibility criteria of a student.

Report of the students attendance can be generated and mail will be send to those who are having short attendance.

Teacher can upload files for students and can also view and download the uploaded files. Students will have the

facility of viewing their attendance and they can download the files uploaded by teacher . Motive is also to bridge

the interaction gap between teacher and student by providing the interaction session between teacher and student.

By E-Attendance+ System we are trying to reduce the manual work to keep record of attendance of students.

Student will get notified by mail if he/she is having short attendance so that he/she can improve his/her attendance to

become eligible for exam. Teachers can manage attendance using computerized data management so that paperwork

can be eliminated. Generate attendance reports any time which help teachers to know whether a student a eligible for

exams.

2. SYSTEM ANALYSIS

2.1 INTRODUCTION

Analysis can be defined as breaking up of any whole so as to find out their nature, function etc. It defines design as

to make preliminary sketches of; to sketch a pattern or outline for plan. To plan and carry out especially by artistic

arrangement or in a skillful wall. System analysis and design can be characterized as a set of techniques and

processes, a community of interests, a culture and an intellectual orientation.

The various tasks in the system analysis include the following.

Understanding application.

Planning.

Scheduling.

Developing candidate solution.

Performing trade studies.

Performing cost benefit analysis.

Recommending alternative solutions.

Selling of the system.

Supervising, installing and maintaining the system.

This system manages to the analysis of the report creation and develops manual entry of the student attendance. First

design the students entry form , staff allocation and time table allocation forms. This project will helps the

attendance system for the department calculate percentage and reports for eligibility criteria of examination .The

application attendance entry system will provide flexible report for all students.

2.2 EXISTING SYSTEM

The Existing system is a manual entry for the students. Here the attendance will be carried out in the hand written

registers. It will be a tedious job to maintain the record for the user. The human effort is more here. The retrieval of

the information is not as easy as the records are maintained in the hand written registers. At the end of the session

calculating the net attendance of students is tedious and time consuming task. Students have to ask from teachers

their attendance in subjects so that they can keep track of their attendance which is also a time consuming task and

headache for teachers and students. Notes given by the teacher to students sometimes not able to reach the whole

class due to miscommunication between students and between student and teacher.

2.3 PROPOSED SYSTEM:

To overcome the drawbacks of the existing system, the proposed system has been evolved. This project aims to

reduce the paper work and saving time to generate accurate results from the students attendance. The system

provides with the best user interface. With the help of this system student can also be notified via mail if they are

having short attendance and students can also see their attendance whenever they want without asking the teacher to

see their attendance. The efficient reports can be generated by using this proposed system. Teacher can also upload

documents containing the required data or can upload the syllabus also. Interaction between teacher and student is

also provided by system to bridge the gap between teachers and students.

2.3.1Advantages of Proposed System

It is trouble-free to use.

It is relatively fast approach to enter attendance.

Is highly reliable,approximate result from user.

Best user interface.

Efficient reports.

4. SOFTWARE DESCRIPTION

4.1 Wamp Server

Stands for "Windows, Apache, MySQL, and PHP ". WAMP is a variation ofLAMP for Windows systems and is

often installed as asoftwarebundle (Apache, MySQL, and PHP). It is often used forweb development and internal

testing, but may also be used to serve live websites. The most important part of the WAMP package is Apache (or

"Apache HTTP Server") which is used run theweb server within Windows. By running a local Apache web server

on a Windows machine, a web developer can test webpages in aweb browser without publishing them live on the

Internet.

WAMP also includesMySQL andPHP,which are two of the most common technologies used for creatingdynamic

websites[3]. MySQL is a high-speed database, while PHP is a scripting language that can be used to access data

from the database. By installing these two components locally, a developer can build and test a dynamic website

before publishing it to a public web server. While Apache, MySQL, and PHP are open source components that canbe installed individually, they are usually installed together. One popular package is called "Wamp Server " which

provides a user-friendly way to install and configure the "AMP" components on Windows.

4.2 HTML

HTML or Hyper Text Markup Language is the standardmarkup language used to create web pages[1]. HTML is

written in the form of HTML elements consisting of tags enclosed in angle brackets (like ). HTML tags most

commonly come in pairs like and , although some tags represent empty elements and so are unpaired, for

example. The first tag in a pair is the start tag, and the second tag is the end tag (they are also called opening

tags and closing tags). A web browser can read HTML files and compose them into visible or audible web pages.

The browser does not display the HTML tags, but uses them to interpret the content of the page. HTML describes

the structure of a website semantically along with cues for presentation, making it a markup language rather than

a programming language. HTML elements form the building blocks of all websites. HTML allows images and

objects to be embedded and can be used to create interactive forms. It provides a means to create structured

documentts by denoting structural semantics for text such as headings, paragraphs, lists, links, quotes and other

items. It can embed scripts written in languages such as JavaScript which affect the behavior of HTML web

pages.Web browsers can also refer to Cascading Style Sheets(CSS) to define the look and layout of text and other

material. When you are browsing a website, your browser (Firefox, Chrome, Internet Explorer etc.) reads an HTML

file in the background, understands the code written in the file and accordingly displays the webpage.Just like you

read a page in a book written in English and your brain automatically understands what it means, a browser also

reads a webpage written in HTML and understands what it needs to show to the user.The HTML head element is a

container for global information about the document. It is placed at the top of the document, inside the html element

but before the HTML body element. Some of the tags that can also be added in head tag.

The tag defines the title of the document:

title-head tag

The tag is used to define style information for an HTML document.

Body{background-color:black;}

A simple example to print this is a paragraph :

this is a paragraph

The entire webpage content is inserted between the and the tags.The text between the and

describe the visible page content.The text between the

and
is the main content of the webpage.
This webpage is designed to output the following text "This is a paragraph".

4.3 CSS

Cascading Style Sheets (CSS) is astyle sheet language used for describing the look and formatting of a document

written in amarkup language.While most often used to change the style ofweb pages and user interfaces written

inHTML andXHTML, the language can be applied to any kind ofXML document, includingplain

XML,SVG andXUL.Along with HTML andJavaScript,CSS is a cornerstone technology used by most websites to

create visually engaging webpages, user interfaces forweb applications, and user interfaces for many mobile

applications.

CSS is designed primarily to enable the separation of document content from document presentation, including

elements such as thelayout,colors, andfonts.This separation can improve contentaccessibility, provide more

flexibility and control in the specification of presentation characteristics, enable multiple HTML pages to share

formatting by specifying the relevant CSS in a separate .css file, and reduce complexity and repetition in the

structural content, such as semantically insignificant tables that were widely used to format pages before consistent

CSS rendering was available in all major browsers. CSS makes it possible to separate presentation instructions from

the HTML content in a separate file or style section of the HTML file. For each matching HTML element, it

provides a list of formatting instructions. For example, a CSS rule might specify that "all heading 1 elements should

bebold," leaving pure semantic HTML markup that asserts "this text is a level 1 heading" without formatting code

.This separation of formatting and content makes it possible to present the same markup page in different styles for

different rendering methods, such as on-screen, in print, by voice (when read out by a speech-based browser

orscreen reader) and on Braille-based, tactile devices. It can also be used to display the web page differently

depending on the screen size or device on which it is being viewed. While the author of a web page typically links

toa CSS file within the markup file, readers can specify a different style sheet, such as a CSS file stored on their own

computer, to override the one the author has specified. If the author or the reader did not link the document to a style

sheet, the default style of the browser will be applied.The CSS specification describes a priority scheme to determine

which style rules apply if more than one rule matches against a particular element. In this so-called cascade,

priorities or weights are calculated and assigned to rules, so that the results are predictable.CSS (Cascading Style

Sheets) defines various ways to style HTML elements. We can use CSS with html in 3 ways:

External - using an external CSS file.

Internal or Embedded - using the element in the tag

Inline - using the style attribute in HTML elements

4.4 PHP

PHP, Hyper Text Preprocessor , is aserver-side scripting language designed forweb developmentbut also used as

ageneral-purpose programming language[2]. As of January 2013, PHP was installed on more than 240

millionwebsites (39% of those sampled) and 2.1 millionweb servers.Originally created byRasmus Lerdorf in

1994, thereference implementation of PHP (powered by theZend Engine)is now produced by The PHP Group.

PHP code can be simply mixed withHTML code, or it can be used in combination with

varioustemplating engines andweb frameworks. PHP code is usually processed by a PHPinterpreter, which is

usually implemented as a web server's nativemodule or aCommon Gateway Interface (CGI) executable. After the

PHP code is interpreted and executed, the web server sends resulting output to its client, usually in form of a part of

the generated web pagefor example, PHP code can generate a web page's HTML code, an image, or some other

data. PHP has also evolved to include acommand-line interface (CLI) capability and can be used

instandalonegraphical applications.The canonical PHP interpreter, powered by the Zend Engine, is free

software released under thePHP License.PHP has been widely ported and can be deployed on most web servers on

almost everyoperating system andplatform, free of charge.Despite its popularity, no written specification or

standard exists for the PHP language; instead, the canonical PHP interpreter serves as a de facto standard. However,

work on creating a formal specification has started in 2014.PHP is an acronym for 'Hypertext Preprocessor', which is

a server side scripting language that can be embedded in html to create dynamic web pages.In simpler terms, HTML

code decides the look of a website, while the PHP code decides its functionality.'' are the opening and

closing tags in which the entire PHP code is written. Any file containing PHP code must be saved with a .php

extension so as to direct the browser that the file is a PHP document.

A simple PHP code to print PHP code on the screen:

A PHP session variable is used to store information about a new session and change its settings. Session variables

have information about a user which is used across multiple web pages. The session data is stored on the server.

A example to demonstrate the concept of storing a session variable and how to retrieve it:

4.5 MySql

MySQL is the world's second most widely used open-sourcerelational database management system . It is named

after co-founderMichael Widenius's daughter,. SQLphrase stands forStructured Query Language. The MySQL

development project has made itssource code available under the terms of theGNU General Public License,as well

as under a variety ofproprietary agreements. MySQL was owned and sponsored by a singlefor-profit firm,

theSwedishcompanyMySQL AB,now owned byOracle Corporation. MySQL is a popular choice of database for

use in web applications, and is a central component of the widely usedLAMP open source web application software

stack (and other'AMP' stacks). LAMP is an acronym for "Linux,Apache,MySQL,Perl/PHP/Python.

5. PROJECT DESCRIPTION

5.1 PROBLEM DEFINITION:

This system developed will reduce the manual work and avoid redundant data. By maintaining the attendance

manually, then efficient reports cannot be generated. The system can generate efficient weekly,consolidate report

based on the attendance. As the attendances are maintained in registers it has been a tough task for admin and staff

to maintain for long time. Instead the software can keep long and retrieve the information when needed. This

system will also send a notification to students via mail if student is having short attendance. With the help of this

system teacher can also upload a file, view file and download a file. This also provides the facility of interaction

between students and teachers.

5.2 PROJECT OVERVIEW

Attendance Management System basically has three main modules for proper functioning. Admin module has rights for creating any new entry of faculty and student details.

Teacher has rights of making daily attendance, upload documents(assignments, syllabus).

Student can see his/her attendance and access uploaded documents after logging into his/her account. He

will be notified whenever any document gets uploaded or if he/she has short attendance.

Interaction(i.e chat) between teachers and students

Report can be generated by teacher which will show status of attendance of lectures, tutorials and net total

for that student and mail will be sent to the student if attendance is short.

5.3

MODULE DESCRIPTION

The system should be designed in such a way that only authorized people should be allowed to access some

particular modules. The records should be modified by only administrators and no one else. The user should

always be in control of the application and not the vice versa.The user interface should be consistent so that the

user can handle the application with ease and speed. The application should be visually, conceptually clear.

5.3.1 ADMINISTRATOR MODULE

Student Details

o In this module administrator can add student.

o Administrator can retrieve information about student such as subjects allotted to student and

other personal detail about the student.

Staff Details

o In this module administrator can add a faculty.

o Administrator can retrieve information about faculty such as subjects allotted to student

and other personal detail about the student.


15/36

15

5.3.2 STAFFS MODULE

Attendance detail

It assists the staff to mark attendance to the students for their subject. Staff can view attendance ,add

attendance and can also add medical benefits if any. This will authenticate the staff before making the entry

by asking for email id and password. Email id and password entered by the staff are matched to one stored

in the database corresponding to the requested user and if they matches person is logged in otherwise an

error message will be displayed to the user and will be headed back to the index page.

Report details

o Faculty can generate a report of the subject.

o A notification will be send to the students via mail if they are having short attendance.

Interaction Details

o

Teacher can interact with students answer their queries over the chat.

o He can upload documents(assignment, syllabus etc.) for students which they can see and download

by logging in.

o He can also see the already uploaded documents.

5.3.3 STUDENT MODULE

Attendance detail

Student can view the attendance of his/her subject by logging in .

Interaction details

o

Student can interact with teacher and can get the response to his/her queries.

o Student can also download the uploaded documents.

6. FEASIBILITY STUDY

Feasibility analysis begins once the goals are defined. It starts by generating broad possible solutions, which are

possible to give an indication of what the new system should look lime. This is where creativity and imagination are

used. Analysts must think up new ways of doing things- generate new ideas. There is no need to go into the detailed

system operation yet. The solution should provide enough information to make reasonable estimates about project

cost and give users an indication of how the new system will fit into the organization. It is important not to exert

considerable effort at this stage only to find out that the project is not worthwhile or that there is a need significantly

change the original goal.

Feasibility of a new system means ensuring that the new system, which we are going to implement, is efficient

and affordable. There are various types of feasibility to be determined. They are:

6.1 Economically Feasibility:

Development of this application is highly economically feasible. The only thing to be done is making an

environment with an effective supervision.It is cost effective in the sense that has eliminated the paper work

completely. The system is also time effective because the calculations are automated which are made at the end of

the month or as per the user requirement.

6.2 Technical feasibility:

The technical requirement for the system is economic and it does not use any other additional Hardware and

software. Technical evaluation must also assess whether the existing systems can be upgraded to use the new

technology and whether the organization has the expertise to use it.

6.3 Operational feasibility:

The system working is quite easy to use and learn due to its simple but attractive interface. User requires no special

training for operating the system. Technical performance include issues such as determining whether the system can

provide the right information for the Department personnel student details, and whether the s ystem can be organized

so that it always delivers this information at the right place and on time using intranet services. Acceptance revolves

around the current system and its personnel.

11. SECURITY

Data encryption is a process of creating secret message formats for data that is stored on computer files. Within

computer software there are multiple encryption techniques available for data files. These techniques are typically

known as encryption algorithms. Each algorithm has unique benefits and usage patterns based on the type of data

and level of protection desired.Unencrypted data is information that can be easily read by acomputer or person.

When data is created on a computer it isautomatically saved in an unencrypted format. This data issaved on

computers or fileservers and can easily be accessedby would-be hackers on the Internet. Encryption techniques are

special processes designed to convert the readable datainto the equivalent of gibberish.Encryption patterns and

standards are managed by the National Institute of Standards and Technology (NIST).

In this system, security is provided by not storing the passwords as in string format but before storing the passwords

in the database a hashing algorithm is provided to convert the password to some encrypted format and then storing

the password in database.

A cryptographic hash function is ahash function which is consideredpractically

impossible to invert, that is,to recreate the input data from its hashvalue alone. These onewayhashfunctions have

been called "theworkhorses ofmodern cryptography".[1]The input data is often called themessage, and the hash

value is oftencalled the message digest or simply thedigest.

The ideal cryptographic hash functionhas four main properties:

Itis easy to compute the hashvalue for any given message.

It is infeasible to generate a message that has a given hash.

It is infeasible to modify a message without changing the hash.

It is infeasible to find two different messages with the same hash.

Hashing is a type of algorithm which takes any size of data and turns it into a fixedlength

of data[5]. This is often used to ease the retrieval of data as you can shorten large amounts of data to a shorter string

(which is easier tocompare). For instance lets say you have a DNA sample of a person, this would consist of a large

amount of data (about 2.23.5 MB), and you would like to find out to who this DNA sample belongs to. You could

take all samples and compare 2.2 MB of data to all DNA samples in the database, but comparing 2.2 MB against 2.2

MB of data cant take quite a while, especially when you need to traverse thousands of samples. This is where

hashing can come in handy, instead of comparing the data, you calculate the hash of this data (in reality, several

hashes will be calculated for the different locations on the chromosomes, but for the sake of the example lets

assume its one hash), which will return a fixed length value of, for instance, 128 bits. It will be easier and faster to

query a database for 128bits than for 2.2 MB of data. The main difference between hashing and encryption is that a

hash is not reversible.

Some hashing algorithms you may encounter are:

MD5

SHA1

SHA2

MD5

MD5 is a hashing algorithm which is still widely used but cryptographically flawed as its prone to collisions. MD5

is broken in regard to collisions, but not in regard of preimages or secondpreimages. The first attacks on MD5 were

published in 1996, this was in fact an attack on the compression of MD5 rather than MD5 itself. In 2004 atheoretical

attack was produced which allowed for weakening the preimage resistance property of MD5. Inpractice the attack is

way too slow to be useful.

SHA

SHA or Secure Hashing Algorithm is a family of cryptographic hash functions published by the National Institute of

Standards and Technology (NIST) as a U.S. Federal Information Processing Standard (FIPS).

Currently threealgorithms are defined:

SHA1:

A 160bit hash function which resembles the earlier MD5algorithm. This was designed by the National Security

Agency (NSA) to be part of the Digital Signature Algorithm. Cryptographic weaknesses were discovered in

SHA1,and the standard was no longer approved for most cryptographic uses after 2010.

SHA2:A family of two similar hash functions, with different block sizes, known as SHA256 and SHA512. They differ in

the word size: SHA256uses 32bitwords where SHA512uses 64bitwords. Thereare also truncated versions of each

standardized, known as SHA224and SHA384.These were alsodesigned by the NSA.

Password hashing requires the following properties:

Have a unique salt per password (salt may only be used once across the database containing allpassword

hashes) to prevent a bruteforce attack of compromising the data in one run.

Fast on software (executing the function once must be relatively fast)

Slow on hardware (executing the function concurrently should be slow, this to prevent brute forcing on

distributed systems).

12. Conclusion

The developed Web-Based Student Attendance System using php ,html and css will significantly improve the

current manual process of student attendance recording and tracking system, especially in a university or school

environment. The system promotes a semi-automated approach in capturing the student attendance, i.e. by marking

attendance manually by teacher on portal. In addition, a number of other advantages are gained by having an online

web-based system, acting as a central repository of student attendance record. Firstly all processes of managing the

student attendance record are performed online, allowing administrators and lecturers to view or modify the users

data through any computer via the web browser, as long as they are connected to the Internet. This way, no specific

software installation is required. The captured student attendance data are also processed and analyze automatically

with less risk of data loss, compared to a manual filing approach. Specific to lecturers or teachers, they can easily

monitor their students attendance online and this could improve the quality of teaching since less time is needed to

manage the student attendance record.

The developed system can be improved and upgraded further, e.g. by extending

the system with new features and modules or by improving the web-interface layout with new display style. Better

yet the system can be enhanced further to offer another significant enhancement where the system can be extended

to monitor staff attendance record. The Attendance Management System fully meets the objectives of the system

which it has been developed. The system has reached a steady state where all bugs have been eliminated. The

system is operated at a high level of efficiency and all the teachers and user associated with the system understands

its advantage. This system solves the problem of not only attendance recording but also other things related to it. It

will automatically sent an email to students whose attendance is going short so they try not to miss classes further. It

will sent mail after submission of attendance to notify students who are about to detain. There is always a problem

of mis-communication between teachers and students, some students didnt get the whole information and irritate

teachers by calling them. An official chat facility for them in students can not only chat but can also see what other

students have said to that teacher. Students can view and download documents uploaded by teachers. It was

intended to solve as requirement specification. The E-Attendance System is planned to overcome the problems

occurred in the current existing system. So this is completely flexible, interactive and informative system which

comes quite handy and also cost effective.

13. Future Scope

E-Attendance system is an efficient and easy way to record attendance. It is a very flexible system for handling as

well as improving. It has a wide future scope. This system is database dependent. Attendance System can be

upgraded to become database independent . So it can run on any system whether its oracle, Mysql etc. We can make

it more informative by adding other informations. We can introduce sessional marks, marks of teacher assessment

along with attendance marks , so it will become internal marks Compiler also. So students will be able to see their

internal marks at the end of session . As teachers can upload documents i.e assignments, syllabus , date sheet of final

exams and result can also be shared. Notification will be sent when they are uploaded.

System can be made more student friendly. A separate section for students can

be created in which they can upload documents and share notes. More student details can be added in student

database and can add some features and make a student portal. Attendance system can be made more flexible by

integrating an android based e-attendance app. But this system is manual dependent on marking attendance by

teacher. Instead of marking attendance manually, we use other techniques :-

1)

Barcode system

2) Finger-print system

3) Facial recognition system

4)

Distance measuring system

Scan barcode of id card of student. Separate database of students will be created for it . In face recognition,

photogragh of student will also be required in database. Distance measuring system measures distance between

teacher and student via tracking their phones location using GPRS. If it less than 50m than that student will be

marked present otherwise will be marked absent.

It will also prevent proxy system , manual error in marking attendance. Above

techniques can be integrated with android application . So e-attendance android app integrated with above

technologies can be created . To keep an extra check on students, we can also add functionality for students to

submit assignments on the portal. A deadline check system would be there which can be programmed to either

reject assignments submitted after last date or deduct marks for assignment according to delay in number of days.
