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

Summary

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