Guide to Steganography
One of the oldest ways to keep a secret or transport a private message is something called steganography, which is the art of writing or encoding a hidden message so that nobody is able to translate it, except the sender and the one who receives the message. This means that people can use steganography to send messages without having to worry that someone else is able to translate them. In the early days, the writing of hidden messages was done on paper only, but in the digital age, people are using steganography and watermarks to hide messages in all kinds of computer files, like recordings or images.
