Steganography Presentation For Students

Steganography is the science and art of concealing the existence of information. It conceals the meaning or content of the existence message. Steganographic systems hide the messages within images or any other digital objects and these messages are invisible. There are two basic principles, i.e., files which have digitized images or sound can be changed to an extent in order to function properly and the inability of human to difference minor changes in image colors or sound quality. The image can be of 16-bit sound, 8-bit or 24-bit image.

Steganography Presentation For Students is to establish conceal communication is very important nowadays with the vast growth of the Internet. The process of steganography is mostly implemented on images. It is the art and science of writing hidden messages such that only recipient knows existence of the message.

 Steganography is used widely in historical times like hidden messages in wax tablets, hidden messages on messenger’s body, and hidden messages on paper in secret links.

This formula provides pieces of the steganographic process:

Cover_medium(image/audio files) + hidden_data + stego_key=stego_medium.

Modern techniques of steganography are hidden text within Web pages, hiding files in plain sight, and null ciphers. These types of steganography are used in conjunction with cryptography such that the information is doubly protected.

The most widely used application of steganography is digital watermarking. It is used to maintain the confidentiality of important information, to protect the data from possible sabotage, theft, and also used for illegitimate reasons. Steganography is still a new idea. It is difficult to detect the large text file within an image.

Conclusion:

Steganography is an effective and fascinating method of hiding data which is used throughout history. There are many reasons to use data hiding that include watermarking for passwords or key processes. However, this technology is easy to implement but difficult to detect.

Voice over Internet Protocol (Voip)

Though Voice over Internet Protocol (VOIP) came into existence several years back, it recently has begun to take off as a public switched telephone networks (PSTN). This technology reduces costs with the help of single IP network to support data and voice applications. Service providers are also attracted by VoIP’s revenue potential. VoIP or Internet telephony is a technology which allows phone calls over the Internet.

 It is necessary to know the basic network functions which allow voice services possible. Here is brief description how PSTN and VoIP networks use. Database services locate endpoints and translate between the addressing schemes in two networks. Signaling to coordinate the actions of the multiple networking components to complete a call between two endpoints. Call connect and disconnect mechanisms to transport audio content. Coder-decoder (CODEC) operations to convert analog waveforms to digital.

 Packet switching sends a small chunk of data from one system to another which is called a packet. The payload is a piece of the e-mail, a music file or any type of file. The computer sends the packet to a router and router sends the packet to another router and so on.

 A typical VoIP network has five major components. They are VoIP phones, consoles and other devices, Call Processing Server/PBX, Media/PSTN-to-VoIP Gateways, IP network, and Session Border Controllers (SBCs). The VoIP network needs media gateways to perform the CODEC functions, i.e., analog-to-digital conversion of voice traffic to create voice IP packets.

Conclusion:

Deploying VoIP is not a simple technology though VoIP is an attractive alternative to traditional PSTN voice services. Before having a VoIP solution, organizations must have required functionality and the potential issues to deploy a VoIP network. It is surely this protocol flexibility which makes VoIP-based voice systems more useful than legacy voice systems. For designing their VoIP solution, Organizations should also remember about latency, jitter, bandwidth, packet loss, reliability, and security issues.

Seminar on Underwater Wireless Communication

Technical Student Seminar on Underwater Wireless Communication is a flourishing research field of wireless communications. Applications like oceanographic data collection, AUVs(autonomous underwater vehicles),underwater radio, transmission of video and audio signals by real time monitoring emphasized to overcome the present limitations.

Wireless is a used to describe the telecommunication with which the electromagnetic waves carry the signal over the communication path. The signals are not radio signals as electromagnetic waves propagate at a short distance so acoustic waves are used that propagate at a long distance. To overcome some impediments, here is an existence of underwater wireless communication. Necessity of underwater wireless system includes temporary experiments, breaking of wires, significant cost for deployment, and experiment over long distances.

Acoustic modems employ advanced modulation scheme and channel equalization to combat multiple paths to have improved signal to noise ratio. A high performance error detection and correction coding scheme is employed which reduces the bit error rate to less than 10-7. Parts of an acoustic modem are DSP board (Digital Signal Processing Board), AFE board (Analog Front End Board), and DC/DC converter.

Underwater networks consist of a number of sensors and vehicles which are deployed to do collaborative monitoring tasks on a given area. There is a traditional approach for ocean bottom monitoring is to deploy underwater sensors which record data and then recover the instruments. With this method, real time monitoring is not possible and failures happen. It can overcome by connecting underwater instruments with the help of wireless links.

Conclusion:

Beside development of the underwater wireless communication, there is an immense scope. Hence more research of the ocean bottom still remains unexploded. Therefore, the main objective about this emerging field is to overcome the present limitations such as the environmental effects on the noise performance of acoustic systems. It is highly affected by heterogeneities of the water column, variations of sound velocity versus depth, temperature and salinity, multiple and random sea reflections and significant scattering by fish, bubble clouds and plankton.

Web Search Engines Seminar For Students

Web Search Engines Seminar For Students is a program that is designed to locate stored data on the World Wide Web (WWW). Search engine indexes are complex and similar. The quality of the indexes breaks or makes the quality of search results.

The large number of users navigates the Web via search engines. It is more likely to display thousands of responses by typing a keyword or phrase and a handful are near to what we searching are located on secondary search pages. A web search engine helps a person to retrieve a number of references that match the content.

The first Web search engine was “Wandex”, collected by the World Wide Web Wanderer and other early search engine is Aliweb and the first “full text” crawler-based search engine was WebCrawler.

 The steps which are involved in processing search engine are Document Gathering-done by Crawlers, spiders, Document Indexing-done by Indexer, Searching, and Visualisation of results. The most emerging technologies in today’s network are Google, yahoo, MSN etc.

 The few challenges include that the web is growing faster than present technology search engine can possibly index, search engine has to revisit periodically, generated sites can be slow or difficult to index, sites are not indexable by search engines and this phenomenon is called invisible web, sites make use of tricks to manipulate the search engine to display them as the first result returned for some keywords. This may lead to search results being polluted.

Conclusion:

The usage of a search engine depends on the relevance of the results it gives back. The methods of search change from time to time as Internet usage changes with new techniques evolve. Most search engines help methods to grade the results to provide the “best” results first. There are other types of search engine that enterprise search engines that search on intranets, personal search engines that search individual personal computers, and mobile search engines.
