Invisible Communication: The Art of Steganography

You can hide secret messages inside innocent photos and nobody would ever know they're

there. This is steganography, the art of invisible communication. Unlike encryption

that scrambles your message into obvious gibberish, steganography hides it in plain sight.

The most common method changes the last bit of pixel data in an image, making changes so

tiny your eye can't detect them. A red pixel stays red, but now carries

your secret. Think of cryptography as a locked safe that everyone sees. Steganography is

invisible ink on a normal postcard. Journalists in oppressive regimes actually use this to bypass

censorship by hiding messages in vacation photos. The best part? Combine both methods.
