cryptography, coding, secret writing, steganographynoun
act of writing in code or cipher
Specifically: The branch of cryptography in which messages are hidden inside other messages; -- used commonly for the process of hiding messages inside a computerized image file, as for example hiding the name and copyright notice of the owner of an image as protection against violation of the copyright.
The practice of hiding messages, so that the presence of the message itself is hidden, often by writing them in places where they may not be found.
Specifically: the use of small files in computers to communicate secret information.
Etymology: From στεγανός + γράφω
Samuel Johnson's Dictionary
The art of secret writing by characters or cyphers, intelligible only to the persons who correspond one with another. Nathan Bailey
Etymology: στεγανὸς and γϱάφω.
Steganography ( (listen) STEG-ə-NOG-rə-fee) is the practice of representing information within another message or physical object, in such a manner that the presence of the information is not evident to human inspection. In computing/electronic contexts, a computer file, message, image, or video is concealed within another file, message, image, or video. The word steganography comes from Greek steganographia, which combines the words steganós (στεγανός), meaning "covered or concealed", and -graphia (γραφή) meaning "writing".The first recorded use of the term was in 1499 by Johannes Trithemius in his Steganographia, a treatise on cryptography and steganography, disguised as a book on magic. Generally, the hidden messages appear to be (or to be part of) something else: images, articles, shopping lists, or some other cover text. For example, the hidden message may be in invisible ink between the visible lines of a private letter. Some implementations of steganography that lack a shared secret are forms of security through obscurity, and key-dependent steganographic schemes adhere to Kerckhoffs's principle.The advantage of steganography over cryptography alone is that the intended secret message does not attract attention to itself as an object of scrutiny. Plainly visible encrypted messages, no matter how unbreakable they are, arouse interest and may in themselves be incriminating in countries in which encryption is illegal.Whereas cryptography is the practice of protecting the contents of a message alone, steganography is concerned with concealing the fact that a secret message is being sent and its contents. Steganography includes the concealment of information within computer files. In digital steganography, electronic communications may include steganographic coding inside of a transport layer, such as a document file, image file, program, or protocol. Media files are ideal for steganographic transmission because of their large size. For example, a sender might start with an innocuous image file and adjust the color of every hundredth pixel to correspond to a letter in the alphabet. The change is so subtle that someone who is not specifically looking for it is unlikely to notice the change.
Steganography is the practice of concealing a file, message, image, or video within another file, message, image, or video. It's a form of security technique that is used to keep information hidden from unintended recipients. The primary goal of steganography is to prevent detection of the hidden information by obscuring it in an unusual communication medium.
the art of writing in cipher, or in characters which are not intelligible except to persons who have the key; cryptography
Etymology: [Gr. stegano`s covered (fr. ste`gein to cover closely) + -graphy.]
Steganography is the art and science of writing hidden messages in such a way that no one, apart from the sender and intended recipient, suspects the existence of the message, a form of security through obscurity. The word steganography is of Greek origin and means "concealed writing" from the Greek words steganos meaning "covered or protected", and graphei meaning "writing". The first recorded use of the term was in 1499 by Johannes Trithemius in his Steganographia, a treatise on cryptography and steganography disguised as a book on magic. Generally, messages will appear to be something else: images, articles, shopping lists, or some other covertext and, classically, the hidden message may be in invisible ink between the visible lines of a private letter. The advantage of steganography over cryptography alone is that messages do not attract attention to themselves. Plainly visible encrypted messages—no matter how unbreakable—will arouse suspicion, and may in themselves be incriminating in countries where encryption is illegal. Therefore, whereas cryptography protects the contents of a message, steganography can be said to protect both messages and communicating parties.
Chambers 20th Century Dictionary
steg-an-og′ra-fi, n. the art of writing in cipher or secret characters.—n. Steganog′raphist, one who writes in cipher. [Gr. steganos, concealed—stegein, to cover, graphein, to write.]
