What is Hidden information?

Hidden information is like a secret message inside your favorite toy that you didn’t know was there.

Imagine you have a puzzle box, it looks simple on the outside, but when you open it, there’s a special surprise inside. Hidden information works in a similar way: it's something that isn't obvious at first, but if you look closely or use the right tool, you can find out what it is.

Think of your backpack, it has books, snacks, and maybe even your lunch. But sometimes, there’s also a note from your friend tucked inside. That note is like hidden information, it wasn’t obvious at first, but if you look carefully or check the right place, you can find it.

Just like how you might use clues to solve a mystery, computers and people sometimes use special ways to uncover hidden information. For example, when you send a message online, there might be hidden information in the background that helps keep your message safe or makes it faster.

It's not magic, it’s just a clever way of hiding something until it's time to find it!
