Open source project fools AI scrapers with poisoned font
ShieldFont, a new open-source project, has been released to protect written web content from unauthorized AI scraping bots through adversarial font poisoning. The technique alters font mapping or glyph rendering, allowing human readers to view standard text normally while automated scrapers and web crawlers extract corrupted, unreadable, or misleading data. The utility is available as an open-source tool for publishers and content owners seeking technical mechanisms to prevent automated ingestion of their text.
