About steganography
Steganograpy comes from ancien greek "steganos" (hidden) and "graphein" (writing). It is the science of hiding secret messages within harmless contents (usually called carriers or covers).
Ancient techniques used invisible inks or letters spacing to dissimulate secret information.
Nowadays techniques rely on computers to hide secret information (such as files) within other files (images, text files, sounds, etc.).
