🧠 How LSB Steganography Works

Least Significant Bit (LSB) steganography hides your message by modifying the least important bits of image pixels. This creates imperceptible changes that are invisible to the human eye but can store secret data.

🎯 Imperceptible

Changes only the last bit of each color channel, creating differences of ±1 in RGB values

🔐 Secure

Messages are encrypted and distributed across multiple pixels, making detection difficult
