Decoy Font
TL;DR
Decoy Font is a TTF font designed to obscure text from AI by embedding decoy letters within each character. It utilizes separate spatial frequencies to create a visual illusion that confuses AI models when reading text.
✦ Why It Matters
Engineers can implement Decoy Font in applications to protect sensitive information from AI text analysis.
Key Takeaways
- Download Decoy Font for personal or commercial use.
- Experiment with the font to test its effectiveness against AI models.
- Consider using similar techniques for private messaging.
- Explore extending Decoy Font to support additional languages.
How It Works
Decoy Font utilizes a clever optical illusion by combining different spatial frequencies to represent two letters in the same space. The foreground features thin outlines, while the background is a blurred mass, allowing the hidden message to be discerned from a distance.
This technique confuses AI models that typically analyze text by focusing on the most distinct visual elements.
