Etymology: Steganography comes from Ancient Greek "steganos," meaning "covered" or "roofed," and "-graphy," from "graphein," "to write." Put together, it literally means "covered writing," which is a fitting description of a method that hides a message inside something else rather than encrypting it into visible gibberish. The idea predates the modern word considerably. Hiding a message in plain sight is an old strategy, and the Greek root points to the same concern: concealing writing under a cover. The "-graphy" element is shared with many English words for writing and recording methods, so the term reads as a straightforward combination of a Greek adjective for covering and a suffix for the act of writing. Modern usage applies the word to hiding data within images, audio, or other digital media, where the carrier file looks ordinary to anyone who does not know to look for the concealed content.
