The web’s newest weapon against AI scrapers is a font

“ShieldFont” aims to poison AI training data without making pages unreadable for people.

The top 3

  1. Most Common CAPTCHA Implementations: reCAPTCHA v2 (checkbox) and v3 (invisible score-based) are widely used, with reCAPTCHA v3 providing a frictionless user experience by returning a risk score without direct interaction.
  2. Advanced Bot Detection and Blocking: Sophisticated methods include Web Application Firewalls (WAFs), rate limiting, IP blocking, browser fingerprinting, and AI/machine learning-based traffic pattern analysis to identify and deter malicious bots.
  3. Innovative Font Obfuscation Methods: New techniques like ShieldFont employ OpenType ligature technology to display one set of words to humans while embedding decoy words in the HTML source code, making scraped data incoherent for AI models.
