Mixfont releases Decoy Font to mislead AI

Decoy Font is a free, experimental TrueType font designed by Mixfont to obscure text from automated AI scrapers and optical character recognition (OCR) systems. Using a hybrid image technique, the font overlays high-frequency decoy outlines for machine vision with low-frequency blurred letterforms readable only by humans.

// ANALYSIS

While Decoy Font is a clever typographic experiment, it offers security through obscurity rather than robust protection, as advanced vision models with basic prompting or spatial-frequency filtering will easily bypass it.

  • Uses the classic Einstein/Marilyn Monroe hybrid image technique to split human and machine perception based on spatial frequency.
  • The release as a TTF font makes it highly accessible compared to other anti-AI techniques that rely on dynamic video elements.
  • It is not a cryptographically secure method; any model trained or prompted to analyze low-frequency backgrounds will easily decode the hidden message.
  • Highly effective as a lightweight captcha alternative or a deterrent against automated visual scrapers.
