Intercom Over LAN

Java Project Definition

        Our project is to implement Intercom over LAN. In this our main aim is to transmit and receive voice data over local area network. The data can be from a file on disk or from a microphone connected to a computer. The resulting software can act as a substitute for existing Intercom in organizations having Local Area Network.

Brief Description. 

VOIP is a technology in which the voice data is transferred over IP network. In our project we are implementing same. For this users has to specify computer name or ip address of the destination computer, so that data reaches the destination We have to implement transmission and reception in between two computers. 

        As our work is to transmit and receive the voice data over LAN so we will divide our problem mainly in two sub problems, which is transmission and reception. So we will write two separate subroutines for each. For communication both subroutines will be running on each computer at the same time.

In our project we are implementing following functionalities:

1. Voice Chat

2. Media File transmission.

3. Automatic Storing of  all Incoming Calls.

4. Calls Forwarding

5. Online friend’s list 

Technology

 Java 2, Java Media Framework (JMF) API.

For developing the above mentioned software we will use JAVA. We have chosen to program in JAVA because of the vast ready made networking libraries which we can use. Java is a “simple , object –oriented , distributed , interpreted , robust , secure, architecture neutral , portable , high – performance , multithreaded  and dynamic language.”

                                     The other main points of using JAVA are that the Java Media Framework (JMF) API provides the support for media capture, transmission, reception and also additional control over media processing and rendering. It also provides a plug-in architecture that provides direct access to media data and enables JMF to be more easily customized. 

“DATA WAREHOUSE”: An Implementation ,Supporting Decision making And Report Generation 

Tools used to implement this are as follows: 

1. SQL SERVER 2000 Ent Edition: It is used to implement the data warehouse which acts as data repository to which data is supplied from all the data sources. It is the offline data base that is updated as per the schedule defined by the administrator.

2. SQL Analysis SERVER: It hosts the OLAP server which contains the multidimensional data that is used by the client for generating the reports based on his queries submitted to it.

3. Microsoft Inter Development Environment: Used for creating the Front end Which is the basic GUI an d the reports generated are also displayed using this tool. .

ADD ONS: 

1. BACKUP: Standby server is implemented for the main data ware house repository.

2. E-mail compatibility using the exchange server.

3. Security: Is defined as per the specifications on the SQL SERVER 2000 and Windows 200 server family.

“COVERT COMMUNICATION BETWEEN USING DIGITAL IMAGES” 

SPONSORED by

technology 

        We have implemented the hiding of data in digital images in spatial domain ( Least Significant Bit (LSB))  and in transform domain (Discrete Cosine Transform (DCT)). We have used Visual C++ to implement the LSB part and for the DCT we have used MATLAB.

 Brief DESCRIPTION    

In the past decade,  steganography was present in various forms e.g. shaving of the head, using invisible ink etc… Steganography as we all know is hiding the very existence of data which separates from the encryption of data in which the data which is transferred is always visible   in some unreadable form.

In today’s world or the digital era we are giving steganography new bounds. By this line  we mean that we are hiding the important message of the user in the digital image, then transferring the stego-image ( image  + data ) to the other end where the original message can be extracted using the user authentication.

The intruder is thus unaware of the communication taking place between the intended users. Hence we enhance the security of the message against any tampering, leakage, modification etc… Thus we are providing a very efficient software in today’s world which preserves the original message at any cost which can be used for many purposes such as :

“COPYRIGHT PROTECTION OF COLORED IMAGES USING DIGITAL WATERMARKING” 

ABSTRACT 

 

      Research in digital data hiding was first triggered by its potential use for copyright protection of multimedia data exchanged in digital form. In this kind of application, usually termed digital watermarking, a code conveying some important information about the legal data owner, or the allowed users of data, is hidden within the data itself, instead of being attached to the data as a header or a separate file. The need to carefully hide the information within the host data is explained by the desire not to degrade the quality of the host signal, and by the assumption that it is more difficult to remove the information needed for copyright protection without knowing exactly where it is hidden.

      In our project we are specifically dealing with the digital colored images as this field has not been explored much and till date most of the work done is concerned with the gray images.

      Thus we can conclude that the study of digital watermarking and this project are going to produce many fruitful results in the very near future for the human race in the field of science and technology which will be used for security purposes which is every body’s need in today’s world.

SYNOPSIS 

 

Project Statement:- 

 

     We are implementing Watermarking Technique for Copyright Protection of colored images. In this we will be embedding a copyright message in the image which will check the authenticity of the legal owner.

          Network Security Solutions (India) Ltd. 

 

Technology:- 

 

     In this project we are using “C” language for the coding on linux platform .The format of the image being used is PPM format.

      We will also be using the concepts of DSF (trees) for storing the sub bands. We will be using some tools such as NetPBM library for various functions like converting jpeg format to PPM format etc.

Brief Project Desctiption:- 

 

      In our project we are using Discrete Wavelet Transform (DWT) technique for embedding and extraction of the watermark.DWT is the most recent technique which has many advantages over the previous techniques like DCT , DFT etc. 

The various stages of the technique are as follows:-

1.      Signature Generation: The mark is a sequence of pseudo random numbers     

 

            which are generated using a seed which in turn is calculated on the basis of the   

            textual message to be embedded. 

 

2.      Decomposition: The host image is decomposed to obtain a multi-resolution

      approximation image using three level DWT.

3.      Coefficient Selection: The coefficients of LL sub band are selected.

4.      Embedding: The watermark is embedded in the approximation image(LL sub

            band ) using the additive embedding  formula:

         F`(i,j) = F_mean + ( F(i,j) – F_mean ) * ( 1 + α * w_i ) 

 

       Where,

                  F_mean  is the average value of all the coefficients.

                  α  is weighting factor.

                  w_i is the watermark.

5.      Extraction: The blind watermark extraction is used which does not need the              

 

            original image. 

 

Platform:- 

      Linux Operating systems.
