Which technique is used to hide the information in a picture?

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.
