Hiding data. The method of secret services. Steganography
Description
"You probably know that to protect sensitive data, you need to store it on an encrypted device. But here's the problem - encryption is visible to the naked eye. An intruder may not be able to get inside, but he will definitely know that you have something valuable stored on your disk. And in some situations, storing encrypted data can be unsafe in itself.
But what if the data is not only encrypted, but also hidden so that no one knows about its existence? This is what steganography is dedicated to - a way to transmit and store information so that no one knows about its existence. This approach appeared in ancient times, was part of the spy craft for many hundreds of years, and in our time has become one of the sections of computer science: digital steganography. You will learn how it works - and you can even try to use it."
