xGovBridge: Cross-Border Health Data Transfer

15 Seconds to First Data Share

Traditional government data sharing requires manual PKI setup, agency registration, share routing configuration, and compliance infrastructure. xgovbridge collapses this to 15 seconds with zero-click accept, 90 seconds with one-line CLI, and 10 minutes with deploy buttons.

Zero-Click Setup (15 seconds)

# 1. Set invite code (from platform onboarding email)
export XGOVBRIDGE_INVITE_CODE=XGB-abc123

# 2. Initiate your first cross-agency data share (auto-accepts invite)
npx @private.me/xgovbridge share \
  --recipient did:key:z6MkDOJ... \
  --data ./case-file.json \
  --threshold 2 \
  --classification LES

What happens:

1. Invite auto-accepted from XGOVBRIDGE_INVITE_CODE env var
2. Agency DID generated and saved to .env
3. Data split via XorIDA (2-of-3 default)
4. Shares distributed to authorized agencies
5. FOIA audit trail initialized
6. Ready for threshold reconstruction

Total time: ~15 seconds

CLI Setup (90 seconds)

# Install CLI globally
npm install -g @private.me/xgovbridge

# Initialize (generates agency DID, saves to .env)
xgovbridge init

# Share your first dataset
xgovbridge share \
  --recipient did:key:z6MkDOJ... \
  --data ./intelligence-report.json \
  --threshold 2 \
  --classification LES

# Output:
# ✅ Data split (2-of-3)
# ✅ Shares distributed to FBI, DOJ, DHS
# ✅ FOIA audit trail initialized
# ✅ Data ID: data_abc123

Deploy Button Setup (10 minutes)

Click one button to provision bridge server + audit logging + FOIA-compliant infrastructure:

Includes:

• Bridge server (K-of-N authorization, share routing)
• FOIA-compliant audit trail (immutable, timestamped)
• Agency registration dashboard
• Jurisdiction enforcement (US-only data residency)
• Classification-based access control (UNCLASSIFIED/LES/FOUO)

The Problem

Cross-border health data transfers between the EU and US are legally complex and technically risky. The EU-US Data Privacy Framework requires adequate safeguards that most organizations cannot demonstrate.

Clinical trials, telemedicine, and health research require sharing patient data across borders. GDPR restricts EU health data transfers to jurisdictions with adequate protection — a standard that shifts with political decisions.

Existing solutions use contractual Standard Contractual Clauses (SCCs) that provide legal, not technical, protection. Schrems II demonstrated that legal frameworks alone are insufficient.

The Old Way

The PRIVATE.ME Solution

xGovBridge provides technical safeguards for cross-border health data: Xshield multi-channel routing splits data across jurisdictions, xRedact minimizes PII, and DID identity authenticates both ends.

Health data is routed via Xshield across multiple independent channels in different jurisdictions. No single jurisdiction holds complete patient data. xRedact strips PII to the minimum required for the specific use case.

DID identity authenticates sending and receiving institutions. Every transfer is HMAC-logged with jurisdiction metadata for GDPR compliance. Data Processing Agreements are cryptographically bound to specific data scopes.

The New Way

How It Works

xGovBridge combines Xshield (multi-jurisdiction routing), xRedact (PII minimization), and DID authentication for cross-border health data compliance.

Use Cases

Integration

import { HealthBridge } from '@private.me/xgovbridge';

const bridge = await HealthBridge.create({
  senderDid: euHospitalDid,
  recipientDid: usResearchDid,
  jurisdictions: ['DE', 'IE', 'US'],
  redactLevels: ['L1', 'L2']
});

Security Properties

Verifiable Data Protection

Every operation in this ACI produces a verifiable audit trail via xProve. HMAC-chained integrity proofs let auditors confirm that data was split, stored, and reconstructed correctly — without accessing the data itself.

Ship Proofs, Not Source

xGovbridge generates cryptographic proofs of correct execution without exposing proprietary algorithms. Verify integrity using zero-knowledge proofs — no source code required.
