New ShieldFont disrupts AI scrapers by altering web text for bots

A new font called ShieldFont has been developed to combat unauthorized AI data scraping. Created by designers Isaque Seneda and Gabriel Abrucio, ShieldFont subtly alters words on webpages through ligatures, making the text nonsensical to AI scrapers while remaining perfectly readable for human users. This method aims to disrupt the collection of training data without resorting to more easily detectable or reversible techniques. AI

IMPACT This tool offers a novel technical workaround for website owners to protect their content from unauthorized AI training data collection.
