# Browser extension security for clinical portals, EHRs, and healthcare research.

How clinicians, medical students, and researchers can safely use AI Chrome extensions on public biomedical literature (PubMed, NCBI) while protecting PHI on clinical portals.

> **Best fit:** Best for healthcare professionals, medical students, and compliance officers setting browser extension boundaries between PubMed research and EHR portals.

## Technical Permission Audit

- **Manifest Key:** `Chrome Site Access Allowlist + Minimal Context`
- **Chrome Install Warning:** Restrict via chrome://extensions -> 'On specific sites' or 'On click'
- **Risk Level:** Higher

```json
// In chrome://extensions -> Vezz me -> Details -> Site access:
// Choose "On click" or allowlist public medical literature domains:
// - https://pubmed.ncbi.nlm.nih.gov/*
// - https://pmc.ncbi.nlm.nih.gov/*
```

### Legitimate Uses
- Explaining clinical trial biostatistics, pharmacology mechanisms, and guidelines on PubMed, PMC, and StatPearls

### Red Flags to Watch For
- Highlighting Protected Health Information (PHI / patient identifiers) in an EHR and sending it to consumer AI endpoints without a HIPAA BAA
- Extensions that automatically read every open tab in the background while an EHR tab is open

**How Vezz me handles this:** Vezz me is strictly user-triggered (never reads background tabs) and works seamlessly with Chrome's 'On specific sites' allowlist so you can enable it on PubMed/NCBI while blocking it completely on hospital EHR domains.

## Step-by-step workflow

1. **Never highlight Protected Health Information (PHI)**: Consumer AI browser extensions should only be used on de-identified educational concepts, medical textbooks, and public clinical studies—never on patient charts.
2. **Scope Chrome site access to public literature domains**: In `chrome://extensions`, set site access to 'On click' or allowlist `*.ncbi.nlm.nih.gov` so the extension cannot run on internal hospital portals.
3. **Use Minimal context when looking up a single drug or lab term**: Minimal context sends only the highlighted drug name or physiological term without surrounding page text.

## Clean separation between medical study and clinical charting

Medical students and residents frequently have PubMed, UpToDate, and an EHR portal open on the same workstation.

- Because Vezz me never scrapes background tabs, having another tab open does not expose it
- Using Chrome's built-in site access controls lets you hard-restrict extensions away from internal `.local` or EHR domains
- Ideal for unpacking statistical endpoints, biochemical pathways, and board-prep vignettes

## Frequently asked questions

### Is Vezz me a HIPAA Business Associate for patient records?

No. Vezz me is a reading and research assistant for web content, academic literature, and documentation—do not select or submit Protected Health Information (PHI) or patient-identifiable data.
