COMPUTER FUNDAMENTALS

Detailed explanation-1: -Steganography is the technique of hiding secret data within an ordinary, non-secret, file or message in order to avoid detection; the secret data is then extracted at its destination. The use of steganography can be combined with encryption as an extra step for hiding or protecting data.

Detailed explanation-2: -Steganography is the science of hiding information. The goal of cryptography is to make data unreadable by third parties, whereas the goal of steganography is to hide the data from third parties.

Detailed explanation-3: -Hidden messages on a paper written in secret inks. Hidden messages distributed, according to a certain rule or key, as smaller parts (e.g. words or letters) among other words of a less suspicious cover text. This particular form of steganography is called a null cipher.

Detailed explanation-4: -Steganography implements an encryption technique in which communication takes place by hiding information. A hidden message is the combination of a secret message with the carrier message. This technique can be used to hide the message in an image, a video file, an audio file or in a file system.
