Explanation
Steganography is the practice of concealing information within another non-secret file or message (such as an image, audio, or video) so that the existence of the hidden data is not apparent to a casual observer. Unlike encryption, which scrambles data so it cannot be read, steganography hides the fact that a message exists at all. Key escrow is a system where encryption keys are held by a third party. A rootkit is malware that provides hidden privileged access. An offset is a memory addressing concept.
