Steganography hiding data in images
An investigator at Corsewall Electronics finds that an employee has been sending ordinary-looking vacation photos to a personal account. Analysis shows design files hidden inside the image data. Which technique was used?
- A.Steganography
- B.Salting
- C.Key escrow
- D.Tokenization
Show answer and explanation
Correct answer: A. Steganography
Why: Steganography conceals data inside other files, such as images or audio, so the hidden content is not apparent. Tokenization replaces sensitive values with tokens, and key escrow stores copies of encryption keys with a trusted party. Salting adds random data to passwords before hashing.
