PRIVATE INSTANT MESSAGING

Abstract

Instant messaging (IM) and chat are technologies that facilitate near real-

time text based communication between two or more participants over a network.

It is important to understand that what separates chat and instant messaging from

technologies such as e-mail is the perceived synchronicity of the communication

by the user - Chat happens in real-time before your eyes. For this reason, some

people consider communication via instant messaging to be less intrusive than

communication via phone. However, some systems allow the sending of messages

to people not currently logged on (offline messages), thus removing much of the

difference between Instant Messaging and e-mail.

Instant Messaging allows instantaneous communication between a numberof parties simultaneously, by transmitting information quickly.

IM allows effective and efficient communication, featuring immediate

receipt of acknowledgment or reply. In certain cases Instant Messaging involves

additional features, which make it even more popular.

The project deals with the development of small instant messaging tool over the

intranet. This will be used with in the small private network.

Activity Control system

Abstract

Activity Control System (ACTITIME) is a time collection software that is streamlined

for billing and invoicing purposes. ACTITIME allows time tracking for customer andproject related tasks. After being collected the data can then be exported for invoicegeneration.

The major tasks, which are performed by the current project are:

1. Create user accounts2. Register billing types (optionally)3. Register customers4. Register projects

5. Add tasks

After completion of these steps we will be ready to submit time-track.

Create user accounts

Login as the Root system user for initial set up of user accounts. To log inprovide username 'root' and password 'manager'.

The Root is a pre-defined system user that always has all access rights exceptthe right for time-track submission. Access rights of the Root user cannot be modified.

The Root user cannot be deleted.

For security purposes change the predefined password of the Root user beforeproceeding with data setup. To change password of the Root user follow theinstructions listed in the section

Add system users and grant them access rights necessary for their everydaywork.

Each user can be granted one or more access rights. The role executed by auser, as well as the category a user belongs to, depend on the access rights granted tothe user. There are no pre-defined user categories (or roles) in ACTITIME. We need togrant a user those access rights that are necessary for his/her everyday work, and thatis all.

If you are going to track overtime, enable overtime tracking when creating useraccounts. Otherwise it is recommended to keep overtime tracking disabled because thiswill simplify interfaces for the time-track submission.

Register billing types (optionally)

If you are going to classify tasks using billing types, create the necessary billingtypes now.

You can skip this step and return to creation of billing types later. In this case allcreated tasks will be associated with the default billing type. If you decide to use non-default billing types, you will have to update this association for all existing tasks aftercreation of the billing types. ,Register customers

ACTITIME collects time expenses for tasks associated with particular project andcustomer. So before creation of tasks you should register at least one customer andone project.

Register projects

Before adding tasks you should create at least one project associated with a customerregistered on the previous step.

ABSTRACT

Attendance through SMS

This system helps the college management to communicate the details of

the attendance and marks to the parents through SMS. This system makes use of

the database built using biometric finger print reader for the attendance.

Then by generating reports on each day it will identify the students who

have less percentage of attendance than the required aggregate percentage .It sends

the messages to the mobiles of the parents about the attendance and marks details.

Apart from this whenever the parents want to know about their students

attendance and marks they can directly login into the site or they can send

message to the administrator by giving that particular students registration number

and they can get return message.

ABSTRACT

AJAX BROWSER

We propose a new web browser for Ajax approach with asynchronous communication

model. Our web browser can improve the operationality that is equivalent to the operationality of

desktop applications without revising program codes of the web applications.

When the user requests for a page, the browser displays the HTML page according to the

source code given by the server. When we click Refresh button, the browser does not load the

whole page again as in classic web application model. Instead, the server compares the existing

page and the requested page and maintains the differences in a difference table. Only those parts

of the page where changes occurred are loaded.

Our browser has the following features

(1) No change of client programs and server programs of web applications,

(2) Asynchronous communication with web servers,

(3) Partial screen update replaces click, wait and refresh user interaction model.

MODULES:

1. Parsing:

HTML source is analyzed by a parser based on HTML tags. Syntax trees are

generated by the parser. Nodes of the syntax tree mean HTML tags; leaves of the syntax tree

mean text contents such as String, numerical, and JavaScript codes.

2. Generating JavaScript:

The original HTML source does not have a function of partial updating.

Therefore, new JavaScript codes are added to the original HTML source. The JavaScript codes


6/24

refer to the difference table. JavaScript codes including innerHTML method are inserted to the

original HTML source.

3. Searching difference:

With comparing the two syntax trees, difference between the two web pages is detected. If

partial update of the web page is required, a difference table is generated. The difference table

includes the difference node information such as tag name, ID, tags properties, text

4. Updating partially:

According to the difference table, a current web page added JavaScript codes updates

partially. In order to update, the current web page accesses to the difference table at constant

intervals. The reason of the constant accessing to the difference table is that the current web page

in the Main block is executed independently from the communication with a web server in the

Sub block. In the Sub block in the model, communication with the web server occurs

corresponding to events such as clicking reload button or automatic reload. In short, the

Main block and the Sub block in the model are executed independently each other. Only

accessing to the difference table is a relationship between the two blocks. Therefore, the

asynchronous communication with web servers can be achieved.

Abstract

Title: Compressor and De-Compressor

In computer science and information theory, data compression or source coding is the

process of encoding information using fewer bits (or other information-bearing units) than anunencoded representation would use through use of specific encoding schemes. One popularinstance of compression with which many computer users are familiar is the ZIP file format,

which, as well as providing compression, acts as an archiver, storing many source files in a

single destination output file.

As with any communication, compressed data communication only works when both the

sender and receiver of the information understand the encoding scheme. For example, this text

makes sense only if the receiver understands that it is intended to be interpreted as charactersrepresenting the English language. Similarly, compressed data can only be understood if the

decoding method is known by the receiver.

Compression is useful because it helps reduce the consumption of expensive resources,

such as hard disk space or transmission bandwidth. On the downside, compressed data must be

decompressed to be used, and this extra processing may be detrimental to some applications. For

instance, a compression scheme for video may require expensive hardware for the video to bedecompressed fast enough to be viewed as it's being decompressed (the option of decompressing

the video in full before watching it may be inconvenient, and requires storage space for the

decompressed video). The design of data compression schemes therefore involves trade-offsamong various factors, including the degree of compression, the amount of distortion introduced

(if using a lossy compression scheme), and the computational resources required to compress and

uncompress the data.

Modules:

Compression Module: This module is used to compress any file to save the disk space. This

includes the usage and implementation of data compression algorithm for the compression of the

files.

De compression Module: This module will take the compressed file as the input and generates or

rebuilds the original file by the implementation of de compression algorithm.

Technologies Used:

Programming Language: Java (Java SDK version 1.5.0)

Operating System: Microsoft Windows Xp with Service Pack 2

ABSTRACT

CRYPTOGRAPHY

When a number of computers are interconnected to form a network, the protectmechanisms within the individual computers become inadequate to ensure the security of data

communications across the network. Preventing the disclosure of original message is not the only

aspect of security in data communication systems; others include protection against alterationsand introduction of false messages.

Cryptography has appeared as the best measure for data security in computer

communication systems by transforming the original data into an unintelligible form. It servesas a countermeasure to passive wiretapping attacks and also as a foundation on which

countermeasures against active wiretapping can be constructed.

There is a strong need for the general tools of utility, which can convert a plain text-fileinto a cipher file and vice-versa, for every user who intend to transfer/ receive text/data on the

network. For this purpose, I implemented the cryptographic techniques as general tools of utility,

which can be used to encrypt / decrypt the files, which roam on the network.

In this project "Implementation of cryptographic techniques for secure file

transfer" three very popular cryptographic techniques: /. Transposition Cipher 2. SubstitutionCipher and 3. RSA (Rivest, Shamir & Adleman) public key cryptographic scheme are

implemented in software written in 'C'.

1. Implementation of Transposition Cipher

In this implementation, the original plain text is transformed by changing the

positions of characters of message plain text. A keyword of 8 characters length is used

to transform the message text and written to the destination file.

The encrypted file may be transferred to the destination where the file is read and arranged

according to the 8-character-key, which is then written on to a file. This file contains the original

message plain text.

2.Implementation of Substitution Cipher

In this implementation, the original plain text is transformed by substituting each character ofthe message plain text by another character. A mono-alphabetic substitution is used in this

implementation.


10/24

Here the key taken is 52 characters length, which contains all the small case and capital

letters of English text, which are used for substitution.

3.Implementation of RSA (Rivest, Shamir & Adleman) public key Cryptographic scheme

Firstly, two large prime numbers p and q, each about 100 decimal digits long are selected and

their product n = p*q is obtained. Then Eulers function z = (p -1) (q - 1) is computed.Choose a number relatively prime to z and call it d. Find e such that e x d = 1 mod z.

To encrypt a message P, compute C = Pe

(mod n). To decrypt C, compute P = Cd

(mod n).

The pair of positive integers (e, n) is termed as the encryption key and the corresponding pair of

integers (d, n) as the decryption key. Each user makes his encryption key public, i.e., known to

everyone on the network and keeps the corresponding decryption key secret with himself

This program is used to encrypt data files and decrypt the encrypted files. As data securitymechanisms can generally be developed independently of

ABSTRACT

Electronic descriptive examination managing system is a computerized way of

conducting present day paper-based descriptive examinations in a university byproviding much user-friendliness to students, staff, invigilators and administrator.

Every student has to submit his user-id, course, year of study, branch, and subject-

code details before taking the exam. This system eliminates the use of paper from

question paper setting to viewing results by the student and also provides the

security to the answer sheets from illegal modifications.

The actors involved are:

1. Student

2. Staff

3. Invigilator

4. Administrator.

After entering into the system, student has to answer the question paper in

the text area provided to him for each question. After writing the exam, the student

submits the exam. To protect the answer sheet from illegitimate modifications, the

system converts it into PDF before storing in the server. Depending on the subject

code, answer sheets belonging to a particular subject are automatically uploaded to

corresponding staffs user. Staff member who is going to correct this particular

subject can access these answer sheets by logging into his user-id. After evaluating

the paper, marks are allotted for each answer depending on his performance. These

marks will be entered into the database by the staff after correcting the paper.

Invigilator logs into the system to authenticate the exam written by the student. He

gives feedback regarding absentees, debarred candidates, technical problems etc to

the system.

After evaluation is carried out, students can view the marks obtained for

each subject, and for each question in each subject.

Administrator is the main person who maintains the system. He performs

main functions like entering and maintaining student details, staff details,invigilator details and exam settings. This system enables us to conduct the exam

process completely from the allocation of invigilators, allocation of staff for

evaluating each subject, allotting marks, viewing marks etc. The main advantage of

the system is that it provides security to the answer sheets written by students.

Abstract

Hiding Info using Video Steganography

The project entitled Video Steganography is the application developed to embed an video file in

another video signal. It is concerned with embedding information in an innocuous cover Speech

in a secure and robust manner. This system makes the Files more secure by using the concepts

Steganography and Cryptography.

Steganography, poor cousin of Cryptography is the art of hiding messages inside other messages

such that the very existence of the message is unknown to third party. The goal of cryptography

is to make data unreadable by a third party, the goal of Steganography is to hide the data from a

third party Through the use of advanced computer software, authors of images and software can

place a hidden trademark in their product, allowing them to keep a check on piracy. This is

commonly known as watermarking. Hiding serial numbers or a set of characters that

distinguishes an object from a similar object is known as finger printing. Together, these two are

intended to fight piracy. The latter is used to detect copyright violators and the former is used to

prosecute them. But these are only examples of the much wider field of Steganography.

The cover data should not be significantly degraded by the embedded data, and the embedded

data should be as imperceptible as possible. The embedded data should be as immune as possible

to modifications from intelligent attacks or anticipated manipulations. Thus it is necessary that

the hidden message should be encrypted.

Job Scheduling and Status Tracking

ABSTRACT

Job scheduling & Status tracking system is a web based application which helps a

workgroup to keep track of tasks (jobs) via a shared central resource.

Job Management is todays most advanced job scheduling application designed to automate

critical IT processes and workloads intelligently across disparate systems and applications to

render business processes securely and reliably.

The data is stored centrally on the server, which make it especially suitable for distributed

teams who can use just the web browser to access it. No local software needs to be installed on

the client system and all web browsers are support.

The main objective of the system is to prioritize the job schedules and allow us to meet

promise dates. Status tracker focuses on workers report on what they have completed, and the

materials they have used in real time. Using terminals out on the shop floor, bar coding, or web-

based reporting, employees can directly enter their time and materials for the jobs they are

working on.

The actual cost of the employees time, materials cost and status of a job is available for

management analysis. Exception reporting when a job is not running as scheduled.Inventory is

also updated.The application itself can be installed virtually on webserver.

Mobile Banking

In todays age of new opportunities and emerging technologies, there is

a new communications infrastructure to transform the way business is

done. Using simple and cheaper hardware such as mobiles and handhelddevices we can communicate & also we can do business transactions. It

provides much better mobility than PCs. Technology is moving towards

mobiles which has wide spread usage and acceptability. Lot of protocols

and softwares has been developed. We are connecting the mobile to

bank database using WML (Wireless Markup Language) scripts and java

technology.

This opportunity is mobile commerce, and it will drive new levels ofintense competition in the finance industry. Mobile commerce achieves

this by removing the traditional restrictions of geographical location and

high entry costs. This time the result on the finance industry will be led

by a new weapon i.e., the mobile phone.

We are providing a wide range of mobile banking for individual clients,

including balance checking, amount transfer, stop payment, request

check book, mini statement, etc.
