Steganography

Steganography is the practice of hiding information within other data so that the presence of the message is concealed. Unlike encryption, which makes content unreadable, steganography makes it invisible by embedding information into digital files like images, audio, or videos in a way that doesn't alter their appearance or sound. This technique is used for secure communication, preventing unauthorized detection of messages. The key idea is to embed data subtly, so only someone aware of the hidden message knows where to look, providing an additional layer of privacy and security in digital exchanges.
