Steganography - English Definition & Meaning

Definition

Steganography is the art of concealing a message within another, seemingly harmless, message. Unlike cryptography, which encrypts the message, steganography hides its existence altogether. Think of it as hiding a secret inside a picture 🖼️. Steganography can involve embedding a message in an image, audio file, or even a text document. The goal is to make the hidden message undetectable to the casual observer. It's like a magic trick where the secret is hidden in plain sight. Steganography is used to protect sensitive information without raising suspicion.

Etymology

The word "steganography" comes from the Greek words "steganos" (covered, concealed) and "graphein" (to write). So, it literally means "covered writing." The practice of steganography dates back to ancient times. Historical examples include messages hidden in wax tablets or tattooed on shaved heads. Modern steganography uses digital techniques to hide messages within various file formats. It has become increasingly sophisticated with the advent of computers and the internet. Imagine a hidden message only visible under a special light!
