Why Your Healthcare RAG Pipeline Is Leaking PHI (And How to Fix It)
Why Your Healthcare RAG Pipeline Is Leaking PHI
Most healthcare organizations believe their AI assistant is secure once they restrict who can log in.
Unfortunately, that's only part of the story.
Modern healthcare AI applications rely on Retrieval-Augmented Generation (RAG), where patient records, physician notes, insurance claims, and medical documents are embedded into vector databases to power intelligent search.
But what happens to Protected Health Information (PHI) during that process?
In this video, we break down one of the most overlooked security risks in enterprise AI and explain why login restrictions alone cannot protect sensitive healthcare data.
You'll learn:
✔ Why PHI gets stored inside vector databases
✔ Why developers, testers, and support teams can unintentionally access patient information
✔ Why traditional access control doesn't solve the problem
✔ How tokenization preserves AI accuracy while protecting patient identities
✔ How Context-Based Access Control (CBAC) ensures only authorized users see sensitive data
If you're building AI applications for healthcare, insurance, life sciences, or any regulated industry, this architecture is essential.

Would you trust an AI assistant with patient records if developers and testers could still access the underlying PHI?
