Steganography is used to hide messages in emails, which are sent from one person to another. The sender and recipient both have to be aware of the hidden message for it to be effective.

Steganography has been around since ancient times and it has been used in many different ways. For example, ancient Greeks would use a wax tablet to hide messages inside of it with charcoal dust that would be removed later.

Email Steganography: Types and Examples

  • Image Based Steganography: This type of steganography uses images to hide the message. It is most commonly used by sending an image with text in a text file attachment. This allows the recipient to view the image while they can't read the text, so it makes it difficult for them to detect that there is anything hidden in the image.
  • Text Based Steganography: This type of steganography hides messages within normal text files, usually by embedding a secret message into an innocuous-looking string of characters or by replacing some letters with symbols

Email steganography is the practice of hiding a message within an email. The purpose of this is to save time and reduce the risk of detection.
