What is Steganography?

Steganography is the procedure by which files or information can be transmitted secretly by embedding them in images or audio files. Cryptographic concepts can be used to supplement steganography by first encrypting the message and then hiding it in the image.

For the ordinary user only an image is visible but to the sender and receiver, a message is hidden in the picture which  can be unearthed only by using special steganographic tools.

In the video illustration  below, we can see that a text file is embedded inside the ‘snowman’ image. There are several steganography tools available like QuickStego, Xiao Steganography, OpenStego and so on which helps us to embed secret files in images or audio files.
