stego-, steg-, stegano- +

(Greek: covering, covered, to cover; roof; by extension, secret, secret writing, applied to a secret code, codes, or ciphers that are hidden)

Closely related to Latin tego-, techo-, "to cover".

In invertebrate zoology, overlaid with two series of spines.
Obstruction of a nasal passage.
Analyzing and deciphering steganographic or secret writing.
A cryptogram or coded message.
A secret message that is hidden in a bigger one in such a way that other people are not aware of its presence or contents; for example, a message might be hidden somewhere in an image by changing the least significant bits to be the message bits.
steganographic, steganographical
A reference to or a description of a secret message that is hidden in an image, an audio, or a video file.

It is used instead of an encryption (secret code) and it takes advantage of unused bits within a computer file structure or secret bits which are mostly undetectable if altered.

A steganographic message can go secretly to its destination, unlike encrypted messages, which although they may be undecipherable without the decryption key, they can be identified as being encrypted or some kind of a coded secret message.

Someone who practices the art of writing in cipher.
steganography (s) (noun)
1. Defined in dictionaries as the art of writing in ciphers or characters that are not intelligible, except to the persons who correspond with each other; cryptography (secret writing).
2. The art and science of communicating in a way that hides the existence of the communication: Steganography attempts to hide messages inside other harmless messages in such a way that third parties cannot even detect the existence of the concealed message or secrets.
3. The science of communicating in a way that hides the existence of the actual communication.

The practice of steganography involves hiding information in a wider bandwidth carrier of secrets.

Steganography covers the techniques used in digital watermarking schemes as an example from modern digital techniques, one could put the text of a message in the blank spaces in an image file.

4. In cryptography, steganography refers to not only obfuscating (encrypting) data or secrets, but hiding the fact that it even exists.
5. The art and science of hiding information by embedding secret messages within other, seemingly harmless messages: Shrinking the secret text of steganography until it is the size of a dot and then putting it in an unsuspected place; such as, the dot on top of a letter "i" in some innocuous or harmless letter.
6. Etymology: from Greek steganos, "covered, concealed, or protected" + graphein, "to write".
