Principle of Steganography Tool BCS (Bilevel Compression by Using Steganography)
In this paper we make a new approach of compression used as a tool of steganography instead of make it as obstacle (BCS).The outline of BCS compression used two steps level 1 and level 2, level 1 is a new approach of compress images which depends on the fact that every paint has a limited colors, that make it reduce the physical size of repeating p
