The correct answer is Steganography

Key Points

  • Steganography is the practice of hiding a secret message within another message or a physical object.
  • It is often used to conceal information within digital images, audio files, or even text documents.
  • Unlike cryptography, which makes the content of a message unreadable to unauthorized users, steganography aims to make the existence of the message undetectable.
  • By embedding information in seemingly innocuous data, steganography allows for covert communication.

Additional Information

  • Cryptography: This is the practice of securing information by transforming it into a secure format. Encryption is a common method used in cryptography.
  • Forensics: This refers to the use of scientific methods and techniques to investigate crimes. Digital forensics involves the investigation of digital data.
  • Image rendering: This refers to the process of generating an image from a model by means of computer programs. It is not related to hiding information.
  • Darknet: The Darknet refers to a part of the internet that is not indexed by traditional search engines and requires specific software, configurations, or authorization to access. It is often used for anonymous communication and activities.
