Communication plays very important role in this world and Digital communication has grown wildly. Conversations that happen through the internet between the source and destination are not secured always. Security is achieved by covering data within other files. This we call it as Steganography. Digital Steganography is hiding data within data. This process is done by covering a message in a carrier file and different algorithms are used to implement steganography.
