There are several components involved with steganography. Which of the following refers to a file that has hidden information in it?

A.
Stego-medium

B.
Concealment cipher

C.
Carrier

D.
Payload

Explanation:
C: Steganography is a method of hiding data in another media type so that the very existence of the data is concealed. Only the sender and receiver are supposed to be able to see
the message because it is secretly hidden in a graphic, wave file, document, or other type of media. The message is not necessarily encrypted, just hidden. Encrypted messages can
draw attention because it tells the bad guy, “This is something sensitive.” A message hidden in a picture would not attract this type of attention, even though the exact same secret
message can be embedded into this image. Steganography is a type of security through obscurity. The components involved with steganog-raphy are the carrier, stego-medium, and
payload. The carrier is a signal, data stream, or file that has hidden information inside of it. In other words, it carries the payload.
A is incorrect because the stego-medium is the medium in which the information is hidden in steganography. If the message were held within a graphic, the stego-medium could be
JPEG or TIFF. If the message were embedded within a file, the stego-medium could be a Word document. A stego-medium can be a graphic type, wave file type, document type, or
other type of media.
B is incorrect because a concealment cipher is a type of steganography method that involves putting a message within a message. It is a way to hide a secret message within
something familiar from the world around us. This answer does not specify a specific component of steganography but is a specific type of steganography.
D is incorrect because the payload is the information that is to be concealed and transported through the use of steganography. The payload is the actual information that the sender
wants to keep secret.
