Computers know a single language: binary, yet they translate every single one of their bits into any human comprehensive interpretation. They show us words in any desired language, movies, images, while for them they only represent a huge string of 0s and 1s.
Steganography, important branch of cryptography, takes huge advantages of the computers' 'native' language and offers a great technique to those who value confidentiality and privateness of their communication. Steganography 'melts' data1 into data2 and, if done correctly, provides a result that is identically to data2.
No computer or foreign eye could know that data1 is present in the result and furthermore could not retrieve data1.
