Security & Compliance

Patient identity never leaves the country — by design, not by policy.

Confer separates who the patient is from what the case is about at the data-model level, encrypts sensitive data at rest, de-identifies imaging before it can be shared, and records every access. Below is exactly how — with real before/after examples — and the regulatory frameworks each control maps to.

01 · The identity firewall

Identity and clinical data live in separate, encrypted stores

A consulting surgeon's view has no code path to the patient's identity — the wall is enforced in the architecture, not just hidden in the interface. Only the right column ever crosses a border.

Identified · stays in UAE · encrypted
  • Patient name
  • Emirates ID
  • Date of birth
  • Contact details
  • Original imaging
Never transmitted
Pseudonymous · shareable
  • Case reference (CNF-····-····)
  • Age · sex · laterality
  • Clinical summary & question
  • De-identified imaging

02 · Encryption at rest

Sensitive fields are AES-256-GCM encrypted in the database

Identifying fields are never stored in plain text. Each value is encrypted with AES-256-GCM (authenticated encryption) under a master key held outside the database. Lookups use a keyed one-way blind index, so we can find a record without ever storing the searchable value in the clear.

Try it — one-way hashing (live)
This computes a live SHA-256 hash in your browser to demonstrate one-way transformation. Confer's blind index uses a keyed variant (HMAC-SHA256) so the value can't be reversed or guessed even with the same input.

03 · Imaging de-identification

PHI is stripped from images before a case becomes shareable

DICOM files carry identity in their metadata tags; ordinary photos carry it in EXIF. Both are removed before the scrubbed copy is generated. Files that can't be safely auto-cleaned (burned-in annotations, PDFs) are held for manual review rather than shared.

Original DICOM tags
(0010,0010) PatientName = MANSOORI^AHMED
(0010,0020) PatientID = 784-1985-1234567
(0010,0030) BirthDate = 19850312
(0008,0090) RefPhysician = Dr S. Khan

04 · Access control & auditability

Least-privilege access, every action recorded

Role & per-case access

A surgeon sees a case only if they own it or were assigned it. The consultant view can never return identity fields.

WhatsApp OTP sign-in

No shared passwords. Access is tied to a verified phone; surgeons are onboarded and approved by an admin.

Immutable audit log

Every sign-in, view, send, upload, download, and opinion is timestamped with actor and object — encrypted at rest.

Session & request hardening

HTTPS-only, HSTS, strict Content-Security-Policy, CSRF tokens on every state change, secure same-site cookies.

05 · Data residency & cross-border transfer

Hosted in the UAE; transfers are gated by recorded consent

All data is stored on UAE-based servers. Routing a case to a surgeon outside the UAE is blocked until cross-border transfer consent is recorded — and even then, only the de-identified, pseudonymous record is sent, never patient identity.

In-country storage

Databases and encrypted files reside on UAE infrastructure.

Consent-gated routing

Cross-border send is refused server-side without a recorded consent for the destination country.

06 · Regulatory alignment

Controls mapped to the frameworks that apply

Confer is engineered to align with the requirements below. This describes implemented technical controls — it is not a certification.

FrameworkCore requirementHow Confer addresses it
UAE Federal Law No. 2 of 2019ICT in Health Fields Health data stored & processed inside the UAE; transfer abroad restricted. UAE-hosted storage; identity never transmitted; cross-border routing sends only de-identified data and is consent-gated.
UAE PDPLFederal Decree-Law No. 45 of 2021 Lawful basis, data minimisation, security, and subject rights over personal data. Encryption at rest, least-privilege access, minimisation (pseudonymous sharing), full audit trail, consent capture.
Abu Dhabi DOHHealth Information & Data Standards Protection, classification and traceability of health information. Identity/clinical separation, encrypted PHI, immutable access log for traceability.
HIPAA (US)Applies to a US recipient, not the UAE platform directly Safeguards for protected health information; de-identification standard. A US consulting surgeon receives a de-identified, pseudonymous case — reducing PHI exposure at the boundary.
Note. This page describes technical controls implemented in the platform for demonstration and explanation. It is not legal advice or a compliance certification. Formal compliance with UAE Federal Law No. 2/2019, the UAE PDPL, Abu Dhabi DOH / DHA policies, and any applicable foreign law (including HIPAA where a US party is involved) requires independent legal and information-security review, and — for cross-border health-data transfer — appropriate regulatory authorisation.
