Explanation
Steganography is the practice of hiding secret information within an ordinary, non-secret file or medium - such as embedding a message inside an image file - so that the existence of the message itself is concealed. This differs from encryption, which obscures the content but not the existence of a message. Transport encryption (A) secures data in transit. Hashing (C) produces a one-way fingerprint and cannot embed messages. A digital signature (D) verifies authenticity and integrity but does not hide data inside another file.
