New tool detects hidden text in documents before AI agents read them

By PulseAugur Editorial · [1 sources] ·

A new tool called HiddenContent.ai has been developed to detect hidden text within documents that could be exploited by AI agents. This issue is significant because hidden text, such as white text on a white background or text in a tiny font, can be read by AI models but is invisible to human readers. A study found that about 1 in 100 résumés contained such hidden prompts, and legal cases have already emerged where individuals faced consequences for using this technique.
