Steganography is the practice of concealing a file, message, image, or video within another file, message, image, or video. Generally, the hidden messages appear to be or be part of something else: images, articles, shopping lists, or some other cover text.
This post would cover Steganography in Kali Linux — Hiding data in image. You can pretty much use the same method to hide data in Audio or Video files. In digital steganography, electronic communications may include steganographic coding inside of a transport layer, such as a document file, image file, program or protocol. Media files are ideal for steganographic transmission because of their large size.

For example, a sender might start with an innocuous image file and adjust the color of every th pixel to correspond to a letter in the alphabet, a change so subtle that someone not specifically looking for it is unlikely to notice it. The advantage of steganography over cryptography alone is that the intended secret message does not attract attention to itself as an object of scrutiny.
Plainly visible encrypted messages—no matter how unbreakable—arouse interest, and may in themselves be incriminating in countries where encryption is illegal. Thus, whereas cryptography is the practice of protecting the contents of a message alone, steganography is concerned with concealing the fact that a secret message is being sent, as well as concealing the contents of the message.
