Steganographic file system

A steganographic file system is a way of hiding files and information inside of other files so that it looks like nothing is there. Think of it like a secret treasure map hidden inside of a regular picture. Just like with a treasure map you need the right instructions to be able to get the secret message and find the treasure. With a steganographic file system, a special software program helps you hide and find the secret information. You can hide your sensitive files and data inside of any type of file, such as music, pictures, or videos, and no one will be able to tell it’s there unless they have the special program that helps you access it.
