Steganography deals with composing hidden messages so that only the sender and the receiver know that the message even exists. Since nobody except the sender and the receiver knows the existence of the message, it does not attract unwanted attention. Steganography was used even in ancient times and these ancient methods are called Physical Steganography. Some examples for these methods are messages hidden in messages body, messages written in secret inks, messages written on envelopes in areas covered by stamps, etc. Modern Steganography methods are called Digital Steganography. These modern methods include hiding messages within noisy images, embedding a message within random data, embedding pictures with the message within video files, etc. Read full article on Steganography here.
