New Fonts Designed to Evade AI Detection

Researchers are developing new fonts that are readable by humans but designed to be unreadable or nonsensical to AI bots, aiming to protect human-written text from automated analysis.

One such font, Decoy Font, uses a hybrid imaging technique with two layers: a clear foreground and a blurred background. This allows for hidden messages, like "Sorry Robot" appearing over "Happy Human."

MixFont's earlier attempt, Ghost Font, used moving words over a shifting background, demonstrating AI perception limits even though it required video format.

The inspiration for Ghost Font came from founder Eric Lu's frustration with AI incorrectly summarizing private text messages.

Another approach, ShieldFont, scrambles about half of the "content words" in text with random words. This makes the text nonsensical to bots, with over 90% being rejected by quality filters.

ShieldFont's creators aim to prevent AI models from stealing human writing, emphasizing that writing involves deliberate choices and effort.

These font developments reflect a growing desire among people to defend against the increasing presence and capabilities of AI in daily life.
