stego

What is the main goal of steganography?

• To encrypt data for confidentiality

• To compress data for transmission

• To hide the existence of data

• To authenticate data origin

Which of the following best describes an overt message in steganography?

• The publicly available file carrying hidden data

• The hidden secret message

• The encryption key

• The algorithm used for embedding data

Which of the following is a major difference between cryptography and steganography?

• Steganography makes data unreadable; cryptography hides it

• Cryptography hides the existence of data; steganography encrypts it

• Cryptography makes data unreadable; steganography hides its existence

• Both are identical in purpose

Which of the following can be used as a host file in steganography?

• Only text files

• Image, audio, or video files

• Only PDF files

• Only image files

Insertion-based steganography hides data by:

• Replacing existing bits with secret data

• Encrypting data before hiding

• Inserting data at specific locations within a host file

• Generating new files from scratch

Which of the following techniques is commonly used in insertion-based steganography?

• Least Significant Bit (LSB) modification

• Vigenère cipher

• RSA Key Pair

• Diffie-Hellman

Grammar-based steganography hides data by:

• manipulating grammatical structure of sentences
• hiding data in images
• encrypting data with passwords
• using color patterns in text

In the new classification scheme, which of the following is not a type of steganography?

• generation

• hashing
• substitution

• Insertion

Substitution steganography works by:

• hiding the secret message in plain sight
• encrypting the cover medium
• replacing bits of the cover medium with bits of the secret message
• compressing the secret message into the cover medium

Generation steganography is different because it:

• focuses on embedding information within the generation process of content
• relies on physical concealment of messages
• emphasizes encryption of data before transmission
• focuses on hiding information in images
