Steganography ,from the Greek, means covered or secret writing, and is a long-practiced form of hiding information. Although related to cryptography, they are not the same. Steganography's intent is to hide the existence of the message, while cryptography scrambles a message so that it cannot be understood.

Steganography includes a vast array of techniques for hiding messages in a variety of media. Among these methods are invisible inks, microdots, digital signatures, covert channels and spread-spectrum communications. Today, thanks to moder ....etc

Choreography



Choreography, in a Web services context, refers to specifications for how messages should flow among diverse, interconnected components and applications to ensure optimum interoperability. The term is borrowed from the dance world, in which choreography directs the movement and interactions of dancers.

Web services choreography can be categorized as abstract, portable or concrete:

*
In abstract choreography, exchanged messages are defined only according to the data type and transmission sequence.
*

Definition
Embedded system is a combination of computer hardware, software and, perhaps, additional mechanical parts, designed to perform a specific function.

Embedded systems are usually programmed in high level language that is compiled (and/or assembled) into an executable (machine) code. These are loaded into Read Only Memory (ROM) and called firmware, microcode or a microkernel. The microprocessor is 8-bit or 16-bit.The bit size refers to the amount of memory accessed by the processor. There is usually no operating system and ....etc

Quantum Information Technology

The subject of quantum computing brings together ideas from classical information theory, computer science, and quantum physics. This document aims to summarize not just quantum computing, but the whole subject of quantum information theory. It turns out that information theory and quantum mechanics fit together very well. In order to explain their relationship, the paper begins with an introduction to classical information theory .The principles of quantum mechanics ....etc
