Healthcare Partnership · Case Study — Secure Document Access

One secure link, zero portal logins for clinical review

A leading U.S. supplier of home-delivered urologic and ostomy products needed to share AI-verified clinical orders with outside physicians, payers and billing auditors without emailing PHI. 10Decoders built a token-gated, zero-footprint viewer that opens any order and its extracted data in under a second from a single expiring link.

Overview

Extraction was fast. Sharing was the bottleneck.

The client's AI pipeline already read incoming faxes, prescriptions and medical records in seconds, checking signatures, 90-day supply boxes and diagnosis-to-product matches. The slow part came next: getting that verified document in front of physicians, discharge planners, payers and auditors who had no account on the internal platform.

The old options were emailing PDFs or forcing outside reviewers through portal sign-ups. 10Decoders replaced both with a signed, expiring hyperlink that opens the original document and its AI-extracted data side by side, logs every view, and leaves nothing behind on the reviewer's device.

Under the Hood

Built on verifiable security, not trust

HMAC-SHA256

Signed Tokens

Every link carries a signed token checked against server secrets; any tampering is rejected.

JWT

Scoped Access

Tokens embed the document ID and expiry, so a link opens one order and nothing else.

TTL Expiry

Self-Closing Links

Links expire automatically after a set window, closing the exposure window without manual cleanup.

In-Memory

Zero Local Footprint

Documents stream into memory only; nothing is cached, stored or written to the viewer's device.

Authentik SSO

Federated Staff Access

Internal staff sign in through enterprise SSO and Active Directory; partners use token-only access.

Audit Log

Full Traceability

Token creation, clicks, PDF views and JSON exports are logged with time, IP and document ID.

Doctors won't manage another password, and PHI can't ride in an email.

The Challenge

  • Verified orders were shared as unencrypted PDF email attachments.
  • Outside clinicians refused to create and remember yet another portal login.
  • Exported PDFs lost their link to the AI-extracted data and signature checks.
  • Shared copies had no expiry and no record of who opened them.

Our Approach

  • Replace attachments with signed, tokenized hyperlinks generated by the pipeline.
  • Make access one click on any browser or phone, with no account or VPN.
  • Show the original document and extracted data together in one synced viewer.
  • Expire every link automatically and log every view for HIPAA audits.

The Approach

The Solution

As soon as the pipeline finishes an order, it generates a unique URL carrying a signed token with the file ID and an expiry time. The link goes out in the automated processing report. When an authorised reviewer clicks it, the server validates the token and renders the full view in under a second.

The reviewer sees the original multi-page PDF on one side and the structured data on the other: patient details, clinician orders and compliance tags. Clicking any field jumps the PDF to the exact page and spot it came from, so a physician or auditor can confirm an order without hunting through the file.

What We Built

Four parts, one secure workflow

01

Token Generation Service

Signs HMAC tokens with file ID and expiry for every processed order and embeds them in unique URLs.

02

Zero-Footprint Viewer

Server-rendered HTML viewer that streams document and data into memory and loads in under 800 ms.

03

Synced Compliance Layout

Page-wise signature, supply-checkbox and handwriting cards linked to exact positions in the PDF.

04

Access & Audit Layer

SSO federation for staff, token-only access for partners, and a full HIPAA-ready event log.

The Shift

What changed for the team

1

No More PHI by Email

Emailing raw medical PDFs to outside reviewers was eliminated entirely.

2

Zero Credential Overhead

No external portal accounts to provision, reset or support.

3

Sub-Second Load Times

Full document and extraction views render in under 800 milliseconds.

4

Days Down to Minutes

Orders that once waited days on outside verification can clear for shipment in minutes.

5

Audit-Ready by Default

Every fulfilment decision is backed by a logged, human-verifiable signature view.

6

Works on Every Screen

Responsive layout runs cleanly on workstations, tablets and clinical mobile devices.

Delivery, Security & IP
