Signal Decoy Font — adversarial typography for human/machine dual messaging

Summary

Decoy Font uses optical illusion to convey different messages to human and machine vision systems. High-contrast outlined letterforms lure and mislead AI optical character recognition while humans read a different tonal pattern at distance or at small size. In the demonstration example the AI read SORRY ROBOT while humans read HAPPY HUMAN. The font was released by the creator of the Mixfont project and was covered by multiple outlets as a free, downloadable TTF typeface positioned as a tool against AI scraping.
