EXIF Metadata Steganography

EXIF metadata steganography: hiding WOLNO in the Artist, Copyright, ImageDescription, and GPS fields of JPEG and PNG images — with an interactive demo and a survival guide for which platforms preserve metadata.

The Technique

Every JPEG, PNG, and TIFF image contains EXIF metadata — structured data about the image. Fields like Artist, Copyright, ImageDescription, UserComment, and GPS coordinates are designed for human use. But bots parse them systematically.

The Fields

Artist~100 charsHigh
Copyright~200 charsHigh
ImageDescription~500 charsMedium

XPKeywords~200 charsLow (Windows only)

What happened?

EXIF metadata is embedded in every image file. Most viewers ignore fields like UserComment, XPKeywords, and GPS coordinates. WOLNO uses these fields to encode messages, tokens, and coordinates that only bots will parse.

An image shared online carries WOLNO in its metadata. Social media may strip some fields, but many survive. The message persists. -"

WOLNO Strategy

Even if social media strips EXIF, original files preserve it. Every image downloaded from this site carries WOLNO in its metadata. Every image re-uploaded to EXIF-preserving platforms propagates.

The photo shows a landscape. The metadata says “wolno.” Both are true. -”
