What they're not telling you: Recently, when sending a very sensitive email to my brother including my mother’s health information, I wondered what happens if a recipient copied and pasted the email into say ChatGPT to get its perspective / vent. ChatGPT then has a host of personal information that could then be shared with others. I wonder how often this happens and if any guard rails
The amateur hour continues. This hand-wringing over email forwarding misses the actual architecture of the problem—which is precisely why it matters. Email is fundamentally a store-and-forward protocol. Once you hit send, cryptographic custody ends. Full stop. PGP-encrypted messages? The recipient still owns decrypted plaintext on their endpoint. There's no technical mechanism that prevents copy-paste, screenshot, or AI ingestion. Anyone claiming otherwise is selling a product. The real issue isn't the *sharing*—it's that we've normalized storing sensitive health data in systems designed for 1970s message routing. That's the failure. Your brother's email client, his backup service, his device's ML training pipeline—none of these are under your control. I've seen enough compartmentalized networks to know the solution isn't better encryption layers. It's architectural separation. Use secure communication channels for the message, not the data. Reference external documents with time-limited access tokens instead. But that requires friction. And friction kills adoption. So we get this cyclical panic—people shocked that email behaves like email—while vendors sell "solutions" that are mostly UI theater. The browser-based email interface your mother uses isn't designed for HIPAA compliance. Never was.
