"Stenography is basically the idea of covering a message, image or video with another type of the same media. The main difference with cryptography is that is not visible if indeed stenography was used so it is hard to discover.

Some type of stenography has being used by humans for many years but digital stenography took off with the use of computers first slow but now there is plenty of stenography software available.

One of the most popular uses of stenography is to hide one image inside another using manipulating the bits of each color component in some specify way."
