Computer Forensics


Abstract :

Forensic computing is the process of identifying, preserving, analyzing and presenting digital evidence in a manner that is legally acceptable.(Rodney Mckemmish 1999).

From the above definition we can clearly identify four components:-

IDENTIFYING
This is the process of identifying things such as what evidence is present, where and how it is stored, and which operating system is being used. From this information the investigator can identify the appropriate recover ....etc

Abstract:A nantenna (nanoantenna) is a nanosopic rectifying antenna, an experimental technology being developed to convert light to electric power. The concept is based on the rectenna (rectifying antenna), a device used in wireless power transmission. A re-ctenna is a specialized radio antenna which is used to convert radio waves into direct current electricity. Light is composed of electromagnetic waves like radio waves but of much smaller wavelength. A nantenna is a very small rectenna the size of a light wave, fabricated using nanotechn ....etc

Abstract
As Internet access becomes a basic necessity, alternative ways to go on-line without a computer will be required by mobile professionals, the visually impaired, and people without access to computers. Voice/speech based interface options will become an important part of the overall solution to access the Internet content. As the need for an alternative access method to the Internet has become evident, progress continues to be made by technologists to provide such solutions.
One key area of focus has been voice-based technology, ....etc

Artificial Intelligence is all about bringing Common Sense, Expert Knowledge, and Superhuman Reasoning to Computers. For the most part, AI does not produce stand-alone systems, but instead adds knowledge and reasoning to existing applications, databases, and environments, to make them friendlier, smarter, and more sensitive to user behavior and changes in their environments. In the domain of Artificial intelligence, various problem-solving techniques have been developed. Though working towards the common goal of making a computer 'intelligent', ....etc

Security System using Biomatrics
Introduction:
Biometrics refers to the automatic identification of a person based on his/her physiological or behavioral characteristics. This method of identification is preferred over traditional methods involving passwords and PIN numbers for various reasons: the person to be identified is required to be physically present at the point-of-identification; identification based on biometric techniques obviates the need to remember a password or carry a token.
With the increased use of c ....etc

Ping of death:Denial of Service Attacks-An Emerging Vulnerability for the Connected Network
abstract
denying access to essential
services by legitimate users is the main aim of the increasing new types of attacks in internet. This maybe through methods like crashing servers or routers, overwhelming the network with huge traffic to degrade the traffic. a readily available software program is all that one needs to launch a denial of service attack(DoS).

How IP Works
Computers share information over the Internet usin ....etc

Data Compression

Abstract :

It is very interesting that data can be compressed because it insinuates that information that we generally pass on to each other can be said in shorter information units (infos). Instead of saying yes a simple nod can do the same work, but by transmitting lesser data. In his 1948 paper, A Mathematical Theory of Communication, Shannon established that there is a fundamental limit to lossless data compression. This limit, called the entropy rate, is denoted by H. The exact value of H depends on the informatio ....etc

Abstract
The nanowires its small gold squares or spirals placed in a specially processed form of polyethylene, to the material used in plastic bags. While others have succeeded in inventing antennas that collect energy from low frequency regions of the electromagnetic spectrum, such as microwaves, infrared rays have proven to be more elusive.

Description of Nanoantenna

Part of the reason is that the properties of the materials change drastically in high frequency wavelengths. The researchers studied the behavior of various ....etc

Abstract
The electronic commerce with digital content over the open, unsecured network like the Internet provides opportunities as well as risks for content providers. So far, most content providers of media and entertainment content such as music, film, or print content have not been successful or profitable in charging consumers for their products. Nor have they been successful in creating the technology frameworks required to remunerate on the one-hand content owners and on the other hand protect against piracy. T ....etc
