UNDERSTAND THE IDEA

Steganography

THE CONCEPT

A least-significant-bit demonstration can store a bit by changing a channel value from 200 to 201. Real image formats and processing may destroy that bit; this is a concept model.

YOUR MISSION

Choose a bit, hide it in a blue-channel value, then reveal the stored bit.
