Watermarking Digital Audio Seminar Report

Introduction to Watermarking Digital Audio Seminar Topic:

Water marking is the process of embedding information into a signal (Audio (or) video) that is difficult to remove the information is carried in the form of signal. If the signal is copied then the information is also copy. A signal may carry several different water marks at the same time. The protection is very important to water mark. Here we are discussing one of the techniques of audio watermarking (SSW). In this technique a narrow band signal is transmitted over a much large bandwidth so that the signal energy presented in any signal frequency is undetectable, and it has a feature that it destroy such watermark requires noise of high amplitude to be added to all frequency bins.

Audio watermarking salient features:

There are some special features for the audio watermarking that s transparent, robust, efficient and independent. It may be classified in two ways.

  1. Temporal watermarking
  2. Special watermarking.

Temporal watermarking:

In this watermarking system the watermark are hidden into the digital audio signals in the time domain.

 Special watermarking:

In this system transfer of frequency is applied such as FFT, SCT & Digital water.

A bit of audio watermarking application:

DC level schema is applied for the audio watermarking. In this schema the DC level shifting in which water mark is embedded by shifting the DC level of the audio signal. And the audio signal does not need the original signal and the watermark. There is no robustness for the frequency marking for filtering as watermark is embedded to all frequency bands. The spread spectrum scheme (SSS) can provide protection against the MP3 compression. A seminar has been prepared in that seminar it is concluded that the watermark can be embedding onto an audio signal wit out detection but being perceived as required.

MCA Seminar Topic on Modern Applications of Object-Oriented Languages

Introduction to Modern Applications of Object-Oriented Languages:

Vortex is an optimizing compiler intended to produce high quality coda for programs written in a heavily-object-oriented style. To achieve this vortex includes a number of intra- and inter procedural static analyses that can exploit knowledge about the whole program being compiled, it includes inter procedural class analysis, class hierarchy analysis, and exhaustive class testing, and profile-guided optimizations such as receiver class prediction &selective specialization.

Object oriented languages are becoming increasingly popular for the development of software systems of all kinds, five object oriented languages namely small talk, java, php, c++, and python were chosen.

Introduction:

Object oriented programming languages include several feature that can be used to make programs more reusable & extensible. Classes support the construction of encapsulated abstract data types, inheritance allows one abstract data type to be implemented as an incremental modification of one or more existing abstract data type. Dynamic dispatching it is a level of indirection between client and implementation . In this it allows a single piece of client code to multiple different  implementation.

Programmers design the application by putting together different pieces of already written code. Each piece of coed is called object. Object can have properties like color, shape , size and data type. Programming with object is quite like working with real-world object.

 Main features that are available in modern object oriented languages are thread visibility, dynamic binding, exception handling. Data structures consisting of includes the inheritance, modularity, polymorphism and encapsulation.

Materials and methods:

Object oriented development:

This system development is an extension of structured programming. It emphasize the benefits of modular and reusable computer code and modeling real-world object.

Object oriented programming is 95% philosophy   and 5% technology.

Concepts of object oriented:

There are 4 properties

  1. Inheritance
  2. Encapsulation
  3. Polymorphism
  4. Abstraction

Latest CSE Seminar Ideas on CDPD technology in Mobile computing

Introduction to  CDPD technology in Mobile computing :

Mobile computing is a computer interaction in which the data is transmitted via computer. Mobile computing involves mobile communication, mobile hardware as well as mobile software .The mobile computing principle is to send and receive the data across the cellular networks.

Mobile data communication it allows the user to transmit data from remote location to other remote location (or) fixed location .This is the biggest problem for the business people. The mobile data communication is dominated by the technology called CDPD.

CDPD networks allow the mobile users to connect to the network across a fixed link and a packet switched system.

CDPD has a sleep mode which allows the device to save the power when not in use.

Existing cellular network architecture:

A cellular network consists of mobile units linked together to switching equipment, which inter connect the different parts of the networks and allow access to the fixed public switched telephone network (PSTN). The tech is hidden from view, it is incorporated in a number of transceivers called base station (BS).

Existing cellular networks based on circuit- switching consists of base station (BS), base station controllers, switching centers, gateways etc. In this base station the physical transmission with fast power control & wireless scheduling and the base station controllers most of the radio resource management. So, when mobile terminal moves to another cell it needs another base station.

 Data communication: (DC)

 Exchange of data from one system to other system it has wide range of applications including file transfer, inter connection between wide area networks, facsimile (fax) electronic mail, access to the internet. The network used in DC is PSTN, leased-lines and ISDN (integrated services date network) and ATM (Asynchronous Transfer mode). These networks are analogy digital using tech such as circuit- switching packet-switching etc.

CDPD technology:

The mobile data communication market is dominated by a technology called CDPD. Its principle lies the usage of the idle time in between existing voice signals that are being sent across the cellular network.

The advantage of this system is that the idle time is very helpful for the business people.

Extending Grids with Cloud Resource Management for Scientific Computing Seminar Report

Introduction to Extending Grids with Cloud Resource Management for Scientific Computing Seminar Topic:

Extending Grids with Cloud Resource Management for Scientific Computing explains about using  super computers, scientific computing is constant to the next levels such as cluster computing, Meta computing. Grid computing gained the high popularity in the field of scientific computing. Scientific computing is a traditional high work load.

Today in this generation cloud computing is emerging as the paradigm for the next generation of large scale scientific computing, the cloud computing has the four main advantages they are

  1. The cloud cannot buy their own hardware they promote the concept of leasing remote resources which frees from permanent maintenance costs and eliminate the burden of hardware.
  2. Cloud technology reduces cost of installation by removing extra hardware applications that need to be added to super computer but fulfills recruitment. To the resources needed. Through the new concept of “scaling-by credit card”.
  3. The concept of hardware virtualization can represent a significant breakthrough automatic and scalable deployment of complex scientific software.
  4. The provision of resources through business relationships contains specialized data Centre companies in offering reliable services which existing grid infrastructure fail to deliver. For scientific applications there exist several integrated environments for transparent programming and high performance.

Background concepts:

There are several workflow execution middle wares for grid computing, it is used to support the new type of cloud infrastructure.

ASKALON:

ASKALON is a grid application. In this the user composes workflow application at a high level of abstraction using a UML graphical modeling tool. The abstract workflow is given in a XML form to the ASKALON middleware services for transparent execution on to the grid.

CLOUD COMPUTING:

It is used for the provisioning services through internet which are built like utilities. The most popular interpretation of cloud computing is infrastructure as a service (iaas).  Iaas provides modern hardware facilities to customers that pay only for what you use effectively.

Virtualization in (iaas) is distributed, automatic, scalable, deployment, installation and maintenance software.

Latest Technical Seminar Topics for CSE 2012 on Antivirus Sandbox

Introduction to  Antivirus Sandbox  Seminar Topics:

Overview:

From the  invention of computer,  there is Malware in the files which destroys the working speed of system called virus. As now the technology develops the new viruses emerges and malicious are develops in the software. Many Antivirus have invented to prevent this malware but it can bear and prevent the encrypting virus. So here we have invented the new Antivirus software called Sandbox.

This protect the documents and creative files from these encrypted virus by checking for the malware before downloading the file through the temporary folder. There are different types of malware like virus, Trojan horse, Worm.

Sandbox:

Sandbox is the computer security that runs the untrusted application and malware documents using the four components.  The building components are the documents that is to be tested, Sandbox container, sandbox controller, system resources.

Working of Sandbox:

The sandbox works based on two applications namely trusted and untrusted application. The trusted application can be accessible since the contents are fully trusted. But untrusted application should be processed in the sandbox. The sandbox works under the restriction such that the application should under the sandbox manager. The sandbox manager alerts the user if any sensitive resources are present in the application. This software works on its own simulation in different platforms. Sandbox gives compact resources for the strange programs to run according to the instruction. It avoids the boot up process through freezing process. The virus works and get manipulates in the simulated area through the thread process. The sandbox avoid this using APIs. If the files processed beyond the restricted area the simulated norman sandbox denies the application and makes it unworkable. 

Advantages of Sandbox:

  1. Supports many Application Program Interface.
  2. Works on many threads simultaneously.
  3. Detect malicious programs.
  4. Supports networks and messaging action.

The another most important application is protection of Day Zero Attack. This is done by proactive monitor. The stranger file entering the computer is desperate and prevent the infection from the danger. After this analysis the system will decide whether the file can enter or dispatch.

Sandbox safe pattern:

There are many models that operates in different environment. They are :

 1.Java Applets,

2. Security system.

3. Unix system.

4. Virtual emulator.

This Sandbox is more preferable than any other techniques like Digital Signature. Since DS scans the file but Sandbox process and operate on the virus files and can works on both trusted and untrusted model.

Seminar on Storage Area Networks

Introduction to  Storage Area Networks Seminar Topic:

Presently, in many organisations the storage capacity is increasing in a very big rate.  Network storage solutions are the one which can cure this state and provide a flexible connecting storage. There are three storage technologies available i) DAS ii) SAN iii) NAS.

In Direct Attached Storage, the Data is stored in hard disk which is attached to the individual server.  The data stored in the individual servers cannot be accessed when the server fails. Storage Area Network is a Network dedicated for storage devices. Additional Storage devices can also be attached to this network. Network Attached Storage is a local area network the data stored in the individual system connected to the LAN can be accessed.

Fibre Channel interface are used in Storage Area Network for Enterprise class storage arrays. With internal connection many modest priced storage array are available. Storage Arrays are the Logical unit for the host servers appears as a disk volume. Many number of external Fibre channel interface are available in Storage arrays in order to connect the host to the disk. Storage array controllers also provide features such as snapshots, clones, mirroring.

Centralised Backup System is linked to SAN to allow operational features in backup and restore operations.  Present backup systems are different, complex and very difficult to manage. The growth of internet, email, personal devices and integrated business made the data growth and there is a need to store and retrieve them.

As the Value of each data varies, Data Categorisation Strategy method is used to categorise the data into High criticality, Medium criticality, Low criticality and some time Mission critical/continuously available.

Reduced hardware costs, Reduced manage storage, Increased productivity, 24hours availability are some of the benefits of the Storage Area Network. But Installation and the configuration of this network is very difficult and time consuming one.

Technical Seminar on Blue Eyes Technology

Introduction to Technical Seminar on Blue Eyes Technology:

The ability of the first generation RADARS are limited to detect only the object and they cannot sense the speed of the object.  From which we can only measure the echo on the screen and it don’t provide us much accuracy.

The intensity of the sound means the frequency of the sound waves seems to change when either the source or the observer are in relative motion. This wat we called as Doppler’s effect.

First the signal is sent from the unit to the moving object and then it receives the one which get reflects back. The speed of the object is obtained by comparing the signal sent and the one which we received.

Anti-radars: i) jamming device ii) detectors. Jamming Devices – SHF oscillators help in transmitting the signals to the speed cameras and collapse the measurement. Besides that the RADAR can detect these jamming signals and signal the police about this. A detector as a simple SHF receiver. These contain a microwave detector and alarm.

RADAR is not affected by rain or any other weather condition. Mist doesn’t have any relative motion with respect to radar and so there no affect in the measurement. The range of the RADAR to sense the speed of the object depends on i) the power of SHF oscillators’ ii) sensitivity of the detector. Power is low in oscillators and which are used in radars. The main problem in the Detector is signaling to noise ratio. RADAR works when a object nears it.

When several objects are moving at several speeds encounter at the RADAR shows the resulting Doppler signal consist of a mixture of signals at various frequencies. Presently the device gets collapsed and determines it as faulty. But now there are systems like DSP, to measure the speed of several objects simultaneously.
