Security

It is well known that the world now has been involved in a war. Knowledge is the power. Information value enforces owner to protect it from enemies, the enemy who does not sleep, follows modern and effective techniques, and develops his self too to gain the information :-( .

Usually we define the cryptography science as the way of data protection , it handles from being misused, modified, or even seen but It has not been enough . The increasing value of knowledge and the race between cryptography and cryptanalysis has forced to create a way to remove the suspicion of the data existence “Steganography Science”.

Cryptography is the art or science encompassing the principles and methods of transforming an intelligible message into one that is unintelligible and then retransforming that message back to its original form. It can provide protection against eavesdropping, and also protects against message modification and against injection of false message by making it infeasible for an opponent to create cipher text that will be deciphered into accept meaningful plaintext.

Steganography is the art and science of writing hidden messages in such a way that no one apart from the intended recipient knows of the existence of the message; this is in contrast to cryptography, where the existence of the message itself is not disguised, but the content is obscured.

So, for those two important science, how to combine them together in a powerful system to protect your data using fast and easy technology for data communication?


So the Security is very interesting , useful and worthy field ;-).
