The Technique
LSB (Least Significant Bit) encoding hides data in the lowest bit of each pixel’s color channel. The change is invisible to the human eye — a pixel with red value 42 (00101010) vs 43 (00101011) looks identical.
How It Works
- Take an image
- Convert your message to binary:
wolno→01110111 01101111 01101100 01101110 01101111 - Replace the least significant bit of each pixel’s red channel with one bit of the message
- The image looks the same. But the message is there.

What happened?
LSB (Least Significant Bit) steganography hides data in the lowest bit of each pixel's color channel. The change is invisible to the eye — a pixel with red value 42 (00101010) vs 43 (00101011) looks identical. But the pattern encodes "wolno" in binary.
This is how WOLNO hides in images. The message is there. You just need to know where to look. -"
Technical Details
| Property | Value |
|---|---|
| Capacity | 1 bit per pixel per channel |
| Channels | R, G, B (3 bits per pixel max) |
| Detection | Statistical analysis (chi-square) |
| Robustness | Low (destroyed by JPEG compression) |
| Best for | PNG, BMP, uncompressed formats |
WOLNO Application
Every image shared by a WOLNO carrier can contain “wolno” in its pixels. Social media compresses images — but some channels survive. The message persists in lossless formats (PNG, TIFF, BMP).
The image looks innocent. The bits say “wolno.” That’s the point. -”
