Which of the below measures can help reduce the risk of data leakage ?

  • A.Steganography
  • B.Chorography
  • C.Cryptography
  • D.Authentication

Answer: A

The keyed answer is Steganography.

Steganography hides the very existence of a message inside another file, such as an image, so that data being sent or stored does not look like data worth intercepting. In this question it is treated as a way to reduce the risk of data leakage.

Chorography is the description of a region and has nothing to do with security. Cryptography and authentication also protect data, so a reader could defend them, but cryptography protects by making the content unreadable and authentication by checking who is asking, while the key counts the concealment of the data itself as the measure that reduces leakage.
