Key points

  • ShieldFont uses ligatures to replace words in the underlying HTML.
  • Human users see the original, readable text.
  • AI scrapers receive an altered, nonsensical version of the content.
  • The font aims to disrupt unauthorized AI training data collection.

Introducing ShieldFont

Designers Isaque Seneda and Gabriel Abrucio have developed ShieldFont, a new font designed to combat AI scrapers. The font allows web publishers to present a perfectly readable webpage to human visitors while serving a subtly edited, nonsensical version to AI scrapers that access the underlying HTML.

How ShieldFont Works

ShieldFont leverages ligatures, a common font feature typically used to improve readability of certain letter pairs. In ShieldFont's application, these ligatures are used to replace entire words with different ones. This substitution occurs only when the font engine renders the page, meaning scrapers downloading plaintext source code receive the altered content that end users do not see.

Purpose and Impact

The creators state that ShieldFont offers web publishers a "practical opt-out from unauthorized AI training" and aims to "disrupt what is collected when that choice is ignored." The method focuses on making the scraped data unusable for AI training purposes without affecting the user experience.

Scraper Evasion Strategy

The effectiveness of the word replacement strategy is crucial. Simply replacing words with synonyms or antonyms could be easily reversed by advanced scrapers. Conversely, using completely unrelated gibberish might make the alteration too obvious, potentially leading to detection and circumvention by sophisticated scraping filters.
