" Practical Approach of Steganography " by Ms. Sakina Zariwala, SVIFS, SVVV, Indore

Steganography is the art and science of writing hidden messages in such a way that no one, apart from the sender and intended recipient, suspects the existence of the message, a form of security through obscurity.The word steganography is of Greek origin and means "concealed writing" from the Greek words steganos meaning "covered or protected", and graphy in meaning "writing". "Steganography means hiding one piece of data within another".
