Steganography, derived from the Greek, literally means, “Covered writing". It is the
science of hiding information in ways that prevent the detection of hidden messages.
Digital technology gives us new ways to apply steganographic techniques, including
one of the most trickery that of hiding information in multimedia likes image, audio and
video. It includes a huge array of secret communications methods that conceal the message's
very existence. These methods include invisible inks, microdots, character arrangement,
digital signatures, covert channels, and spread spectrum communications. Steganography and
Cryptography are cousins in the spycraft family. Cryptography scrambles a message so it
cannot be understood while Steganography hides the message so it cannot be seen.
A message in ciphertext, for instance, might arouse suspicion on the part of the recipient
while an “invisible" message created with steganographic methods will not.
The purpose of the presented white paper is to provide momentary information in the
area of Steganography with illustrations of some methods for Steganography. Providing and
evaluating steganographic methods with experiments. In this article image files are discussed
and how to hide information in them
