Question

Which of the following correctly describes steganography? Select all that apply.

A). It is a type of security through obscurity.
B). Steganography is a hashing technique
C). Steganography is more secure than encryption.
D). Media files are often used for steganography

Answer 1

Steganography is a method of hiding data within other non-secret files, serving as security through obscurity. It is not a hashing technique and its security compared to encryption is debatable. Media files are often used for steganographic purposes.

Step-by-step explanation:

Steganography is a digital technique used to hide messages or data within other non-secret, public files so that the presence of the hidden message is not apparent. It can be seen as a form of security through obscurity, which is a concept where the security of a system relies on its details being unknown to potential attackers.

Let's address each point provided:

• A) is correct - steganography is indeed a type of security through obscurity.
• B) is incorrect - steganography is not a hashing technique; hashing is used to transform data into a fixed-size value or a hash, while steganography involves embedding data into another file or data stream.
• C) is debatable - steganography may not necessarily be more secure than encryption, as they serve different purposes. Encryption protects the content of a message, whereas steganography hides the existence of the message.
• D) is correct - media files, like images or audio files, are commonly used for steganography, because their large sizes and complex data patterns can easily hide additional information without noticeable changes.
