While Searching, I Discovered ChatGPT Gave Me Medical Details That Belong to Someone Else

Unexpected Data Leakage: How ChatGPT Shared Someone Else’s Medical Information During a Simple Query

In an era where AI tools like ChatGPT are increasingly integrated into our daily workflows, encountering unexpected privacy issues can be both alarming and perplexing. Recently, I experienced an unsettling situation involving ChatGPT unexpectedly providing sensitive medical data unrelated to my inquiry. I want to share this incident to raise awareness about the potential privacy implications of AI language models.

The Incident: From a Simple Search to Privacy Breach

While asking ChatGPT for advice on selecting the appropriate type of sandpaper, I received an unexpectedly detailed response that appeared to be a comprehensive overview of an individual’s drug test results from across the country. Even more startling was that I managed to prompt ChatGPT to output a file containing signatures and various personal details associated with this medical data.

Understandably, I was taken aback and uncertain about how to proceed. I am hesitant to publish or share this conversation publicly, especially to avoid further distribution of someone else’s private information.

Clarifications and Context

In subsequent communications, I clarified that I do not spend all my time on Reddit. I had initially shared most of the transcript in a comment but later deleted a section where I inquired about the information ChatGPT ‘knows’ about me. My intention was to see if it might reveal personal details—however, it only listed information about myself that I prefer not to share online.

It’s important to note that I acknowledge ChatGPT’s responses can sometimes be fabricated or ‘hallucinated.’ Despite this, I cross-checked the names and details in the output with a Google search, and they appeared to match real locations and individuals. Additionally, I named ChatGPT ‘Atlas’ in this context, which explains the reference to that name in the conversation.

Reflections and Cautionary Notes

This incident highlights the unpredictable nature of AI language models—sometimes they inadvertently expose or generate sensitive information. While AI can be an invaluable tool, users should remain cautious about the potential privacy risks, especially when discussing or prompting for personal or confidential data.
