e/Steganographic filesystem

Information
has gloss	eng: Steganographic file systems are a kind of file system first proposed by Ross Anderson, Roger Needham, and Adi Shamir. Their paper proposed two main methods of hiding data: in a series of fixed size files originally consisting of random bits on top of which vectors could be superimposed in such a way as to allow levels of security to decrypt all lower levels but not even know of the existence of any higher levels , or an entire partition is filled with random bits and files hidden in it.
