Steganography

Steganography definition

Steganography is a method or technique that both cybercriminals and ordinary organizations use to hide information within regular files or messages. You can use steganography to hide secret information from hackers and people who shouldn’t see that information. The files and messages pass through the network like any regular files and messages would. And when they reach the end user, the user can extract them. Once they’re extracted, the end user can read the hidden information safely. Many people use steganography and encryption together to further protect the information they want to send from hackers and unauthorized users. Some examples include hiding messages in audio files, video games, and photos.
